serological survey of avian influenza virus infection in non-avian wildlife in xinjiang, china.we conducted a serological survey to detect antibodies against avian influenza virus (aiv) in gazella subgutturosa, canis lupus, capreolus pygargus, sus scrofa, cervus elaphus, capra ibex, ovis ammon, bos grunniens and pseudois nayaur in xinjiang, china. two hundred forty-six sera collected from 2009 to 2013 were assayed for antibodies against h5, h7 and h9 aivs using hemagglutination inhibition (hi) tests and a pan-influenza competitive elisa. across all tested wildlife species, 4.47 % harbored ...201626733295
119 assessment of ovarian follicular dysplasia utilizing ultrasound and histologic examination.a slaughterhouse study commissioned by florida cattleman's association in 2007 identified ovarian follicular dysplasia (ofd) as a primary cause of infertility in florida beef cows. ovaries with ofd have progressive bilateral development of solid clustered follicles containing multiple call-exner bodies that originate in the rete ovarii and the hilar region, and progress into the cortex to eventually form bilateral sertoli-type granulosa theca cell tumours (gtct). the objectives of this study wer ...201628278916
escherichia coli o157:h7 in wild boars (sus scrofa) and iberian ibex (capra pyrenaica) sharing pastures with free-ranging livestock in a natural environment in spain.wild ungulates have greatly increased in abundance and range throughout europe. this new situation presents a concern for public health because many wild ungulates are known reservoirs of zoonotic pathogens.201525807206
campylobacter shared between free-ranging cattle and sympatric wild ungulates in a natural environment (ne spain).campylobacter infections are a public health concern and an increasingly common cause of food-borne zoonoses in the european union. however, little is known about their spill-over from free-ranging livestock to sympatric wild ungulates, especially in regards to uncommon campylobacter species. in this study, we aim to determine the prevalence of c. coli, c. jejuni and other c. spp. in game ungulates (wild boar sus scrofa and iberian ibex capra pyrenaica) and free-ranging sympatric cattle in a nat ...201424595731
fertilization capacity of cryopreserved iberian ibex epididymal sperm in a heterologous in vitro fertilization assay.in vitro fertilization (ivf) can be used to assess the fertilization capacity of sperm. heterologous ivf may be useful when assessing that of wild animals as it is often difficult to obtain adequate numbers of naturally corresponding oocytes. the aim of the present study was to assess the fertilization capacity of frozen-thawed ibex epididymal spermatozoa via heterologous ivf involving the oocytes of prepubertal domestic goats. the effect on fertilization and embryo development of adding oestrou ...201524286139
oestrosis in asiatic ibex (capra sibirica): a case report and molecular characterization of larvae.three third-instar oestrus larvae were found in the frontal sinus of an adult female asiatic ibex (capra sibirica) in the tian shan mountain range, kyrgyzstan. the larvae were identified as oestrus ovis based on morphology and after sequencing and analyzing a fragment of the cytochrome oxidase i (coi) gene. in light of this identification and the fact that asiatic ibex and livestock are sympatric in many areas in central asia, we discuss the risks of interspecific parasite spillover.201728288765
molecular analyses reveal unexpected genetic structure in iberian ibex populations.genetic differentiation in historically connected populations could be the result of genetic drift or adaptation, two processes that imply a need for differing strategies in population management. the aim of our study was to use neutral genetic markers to characterize c. pyrenaica populations genetically and examine results in terms of (i) demographic history, (ii) subspecific classification and (iii) the implications for the management of iberian ibex.201728135293
influence of seasonality and stimulus of oestrous does in bucks' aggressiveness.aggressiveness is directly related to testosterone concentration, which varies with seasons and in response to female stimulation. the aim was to determine if the frequency and pattern of agonistic interactions between bucks varies seasonally and in response to oestrous female stimulation. in the first study we characterized the pattern of agonistic interactions during feeding throughout a whole year in groups of iberian ibex bucks; and in the second study, we determined the influence of oestrou ...201627744086
description and experience: how experimental investors learn about booms and busts affects their financial risk taking.a few years ago, the world experienced the most severe economic crisis since the great depression. according to the depression baby hypothesis, people who live through such macroeconomic shocks take less financial risk in their future lives (e.g., lower stock market participation). this hypothesis has previously been tested against survey data. here, we tested it in a simulated experimental stock market (based on the spanish stock index, ibex-35), varying both the length of historical data avail ...201627771540
evaluation of three enzyme-linked immunosorbent assays for sarcoptic mange diagnosis and assessment in the iberian ibex, capra pyrenaica.sarcoptic mange is a contagious skin disease caused by the mite sarcoptes scabiei, affecting different mammalian species worldwide including the iberian ibex (capra pyrenaica), in which mortalities over 90 % of the population have been reported. no efficient diagnostic methods are available for this disease, particularly when there are low mite numbers and mild or no clinical signs. in this study, three enzyme-linked immunosorbent assays (elisa) developed for dog (elisa a), cantabrian chamois (r ...201627769278
what shapes fitness costs of reproduction in long-lived iteroparous species? a case study on the alpine ibex.the fitness costs of reproduction can be masked by individual differences, and may only become apparent during adverse environmental conditions. individual differences, however, are usually assessed by reproductive success, so how fitness costs are influenced by the interplay between the environmental context and overall individual differences requires further investigation. here, we evaluated fitness costs of reproduction based on 15 yr of monitoring of individual alpine ibex (capra ibex) durin ...201627008789
toxic and essential element concentrations in iberian ibex (capra pyrenaica) from the sierra nevada natural park (spain): reference intervals in whole blood.iberian ibex (capra pyrenaica) blood samples from the sierra nevada natural park (spain) were analyzed to establish concentrations of toxic and essential elements. samples (whole blood from 32 males and 34 females) were taken from wild animals and the concentrations of inorganic elements considered as (1) non-essential and toxic (pb, cd and as), (2) essential but potentially toxic (cu, zn and mn) and (3) occasionally beneficial (b, cr, al and ni), as well as (4) essential minerals (ca, na, k, p, ...201626687500
sex-biased severity of sarcoptic mange at the same biological cost in a sexually dimorphic ungulate.in sexually dimorphic species, male susceptibility to parasite infection and mortality is frequently higher than in females. the iberian ibex (capra pyrenaica) is a sexually dimorphic mountain ungulate endemic to the iberian peninsula commonly affected by sarcoptic mange, a chronic catabolic skin disease caused by sarcoptes scabiei. since 1992, sarcoptic mange affects the iberian ibex population of the sierra nevada natural space (snns). this study aims at exploring whether mange severity, in te ...201526555065
sarcoptic mange breaks up bottom-up regulation of body condition in a large herbivore population.both parasitic load and resource availability can impact individual fitness, yet little is known about the interplay between these parameters in shaping body condition, a key determinant of fitness in wild mammals inhabiting seasonal environments.201526546209
lungworms in alpine ibex (capra ibex) in the eastern alps, italy: an ecological approach.host-parasite relationships have been frequently investigated in mountain dwelling ungulates, though mostly focusing on gastrointestinal nematodes. on the contrary, very few studies were conducted on broncopulmonary nematodes, which may result in severe parenchymal lesions and act as predisposing factor for multifactorial pneumonia. the epidemiological and ecological features of lungworms infecting an alpine ibex population in the eastern alps, italy, were non-invasively investigated by means of ...201526476915
successful ultrarapid cryopreservation of wild iberian ibex (capra pyrenaica) spermatozoa.a method for cryopreserving wild ibex sperm at high cooling rates was developed. to design a freezing solution based on tris, citric acid, and glucose (tcg), two preliminary experiments were performed using glycerol (gly) and dimethyl sulfoxide (dmso) at different concentrations (5%, 10%, 20%). the 10% gly + 10% dmso combination reduced (p < 0.05) frozen-thawed sperm motility, which reached a minimum when 20% gly + 20% dmso was used. in the second experiment, sperm tolerance to three sucrose con ...201526316218
molecular characterization of bot flies, oestrus spp., (diptera, oestridae), from domestic and wild bovidae hosts.the identification of oestrus spp. larvae from bovidae hosts is a difficult task due to the great morphological similarity between species. the lack of unambiguous identification criteria could have also serious epidemiological implications since domestic and wild hosts are sympatric in many natural areas. in order to accurately identify the oestrus parasitizing hosts, we characterized two different genetic markers, 28s (rrna) and coi, in larvae collected from domestic sheep and goats, european ...201526298510
sarcocystis oreamni, n. sp. (apicomplexa: sarcocystidae) from the mountain goat (oreamnos americanus).numerous species of sarcocystis have been reported from wild ruminants, but none has been named from the rocky mountain goat (oreamnos americanus). mature sarcocysts were found in frozen muscle samples of three of seven mountain goats from alaska, usa. two morphological types of sarcocysts were found; one had sarcocystis cornagliai-like sarcocysts, previously named from the alpine ibex (capra ibex) from europe. two other goats were infected with a new species, sarcocystis oreamni. sarcocystis or ...201526255900

acute phase proteins increase with sarcoptic mange status and severity in iberian ibex (capra pyrenaica, schinz 1838).sarcoptic mange is a contagious skin disease caused by sarcoptes scabiei, affecting both domestic and wild mammals, including the iberian ibex (capra pyrenaica), a medium-sized mountain ungulate almost endemic to the iberian peninsula. acute phase proteins (apps) could be an indicator of sarcoptic mange disease and severity in iberian ibex. serum samples from 131 healthy and sarcoptic mange-affected iberian ibexes were collected from 2005 to 2012 in sierra nevada natural space in southern spain. ...201526227139
physiological responses and characteristics of sperm collected after electroejaculation or transrectal ultrasound-guided massage of the accessory sex glands in anesthetized mouflons (ovis musimon) and iberian ibexes (capra pyrenaica).the objective was to characterize the stress response and the seminal parameters obtained with electroejaculation (ee) or transrectal ultrasound-guided massage of the accessory sex glands (tumasg) in two captive but nondomestic ruminants, the mouflons and the iberian ibex under general anesthesia. in mouflons, the physiological responses (heart and respiratory rate, rectal temperature, cortisol, creatine kinase, potassium and glucose concentrations) changed similarly with both procedures. the tu ...201526174035
assessing the impact of capture on wild animals: the case study of chemical immobilisation on alpine ibex.the importance of capturing wild animals for research and conservation projects is widely shared. as this activity continues to become more common, the need to assess its negative effects increases so as to ensure ethical standards and the validity of research results. increasing evidence has revealed that indirect (physiological and behavioural) effects of capture are as important as direct risks (death or injury) and that different capture methodologies can cause heterogeneous effects. we inve ...201526111118
genetic rescue: a safe or risky bet?small and isolated populations face threats from genetic drift and inbreeding. to rescue populations from these threats, conservation biologists can augment gene flow into small populations to increase variation and reduce inbreeding depression. spectacular success stories include greater prairie chickens in illinois (westermeier et al. ), adders in sweden (madsen et al. ) and panthers in florida (johnson et al. ). however, we also know that performing such crosses risks introducing genes that m ...201526013990
ibex: an open infrastructure software platform to facilitate collaborative work in radiomics.radiomics, which is the high-throughput extraction and analysis of quantitative image features, has been shown to have considerable potential to quantify the tumor phenotype. however, at present, a lack of software infrastructure has impeded the development of radiomics and its applications. therefore, the authors developed the imaging biomarker explorer (ibex), an open infrastructure software platform that flexibly supports common radiomics workflow tasks such as multimodality image data import ...201525735289
descriptive analysis of sperm head morphometry in iberian ibex (capra pyrenaica): optimum sampling procedure and staining methods using sperm-class analyzer ®.sperm morphology has been identified as one characteristic which can be useful in prediction of fertility in a species. the development of computer automated sperm morphometry analysis allows for objective analysis of sperm head dimensions. the aim of the current study was to develop an optimum sampling procedure to characterize the iberian ibex (capra pyrenaica) sperm head morphometrically. fresh semen from 11 males was collected using transrectal ultrasonic-guided massage of accessory sex glan ...201525721563
age-specific reproductive success and cost in female alpine ibex.in female mammals, reproduction requires high energy expenditure because of gestation and lactation, possibly leading to a fitness cost. several studies, however, failed to find the expected negative correlation between current and future reproductive success, likely because of individual heterogeneity in reproductive potential. we compared reproductive performance and costs of reproduction for 40 female alpine ibex in one established population with 29 females translocated from the same populat ...201525543851
neanderthal exploitation of ibex and chamois in southwestern europe.there is increasing evidence that neanderthals had a diverse and flexible diet. they exploited a wide range of resources from large proboscideans to small animals like turtles, rabbits, and marine species. here, we discuss the importance of ibex and chamois in neanderthal hunting strategies. the exploitation of both animals has traditionally been regarded as typical of homo sapiens hunting behavior but was not a feature of neanderthal behavior, which was thought to have focused on other kinds of ...201525481629
direct and indirect causal effects of heterozygosity on fitness-related traits in alpine ibex.heterozygosity-fitness correlations (hfcs) are a useful tool to investigate the effects of inbreeding in wild populations, but are not informative in distinguishing between direct and indirect effects of heterozygosity on fitness-related traits. we tested hfcs in male alpine ibex (capra ibex) in a free-ranging population (which suffered a severe bottleneck at the end of the eighteenth century) and used confirmatory path analysis to disentangle the causal relationships between heterozygosity and ...201525392468
distinguishing disease effects from environmental effects in a mountain ungulate: seasonal variation in body weight, hematology, and serum chemistry among iberian ibex (capra pyrenaica) affected by sarcoptic mange.our study focuses on the iberian ibex (capra pyrenaica) from the sierra nevada natural space (southern spain), where sarcoptic mange is an endemic disease and animals are affected by a highly seasonal environment. our aim was to distinguish between disease and environmental influences on seasonal variation in body weight, hematology, and serum biochemistry in iberian ibex. we sampled 136 chemically immobilized male ibexes. the single effect of mange influenced hemoglobin, hematocrit, mean corpus ...201525380360
sperm selection by capripure(®) density-gradient centrifugation versus the dextran swim-up procedure in wild mountain ruminants.this study compares the effectiveness of two methods of sperm selection - capripure(®) density-gradient centrifugation (dgc) and dextran swim-up (dsu) - in semen samples from iberian ibex (capra pyrenaica) and european mouflon (ovis musimon). during the increasing photoperiod, capripure(®) dgc improved the percentage of sperm with progressive motility (p<0.05) in ibexes, and selected 60.6% of the initial total number of spermatozoa contained in the ejaculate samples. in mouflon, capripure(®) dgc ...201425064561
cryopreservation of epididymal sperm from ibexes (capra pyrenaica) using short equilibration time with glycerol.two experiments were conducted to study the effect of shortening the equilibration time with the cryoprotectant glycerol before freezing epididymal sperm recovered postmortem from iberian ibex. in the first experiment, the standard equilibration time of 3 hours was compared with 2 hours, and subjective sperm motility and quality of movement were greater (p < 0.05) in the latter group. in the second experiment, reducing the equilibration time from 2 hours to 15 minutes did not affect sperm motili ...201424938799
sperm characteristics and heterologous in vitro fertilisation capacity of iberian ibex (capra pyrenaica) epididymal sperm, frozen in the presence of the enzymatic antioxidant catalase.the aim of this work was to evaluate the protective effect of catalase (cat) on frozen/thawed ibex epididymal sperm recovered post mortem, and to detect any harmful effect this might have on sperm fertilisation capacity. epididymal spermatozoa were diluted using a tris-citric acid-glucose medium (tcg) composed of 3.8% tris (w/v), 2.2% citric acid (w/v), 0.6% glucose (w/v), 5% glycerol (v/v), and 6% egg yolk (v/v). sperm masses from the right epididymis were diluted with tcg medium, while those f ...201424699464
postural laterality in iberian ibex capra pyrenaica: effects of age, sex and nursing suggest stress and social information.most studies of lateralized behaviour have to date focused on active behaviour such as sensorial perception and locomotion and little is known about lateralized postures, such as lying, that can potentially magnify the effectiveness of lateralized perception and reaction. moreover, the relative importance of factors such as sex, age and the stress associated with social status in laterality is now a subject of increasing interest. in this study, we assess the importance of sex, age and reproduct ...201424611891
global anisotropies in tev cosmic rays related to the sun's local galactic environment from ibex.observations with the interstellar boundary explorer (ibex) have shown enhanced energetic neutral atom (ena) emission from a narrow, circular ribbon likely centered on the direction of the local interstellar medium (lism) magnetic field. here, we show that recent determinations of the local interstellar velocity, based on interstellar atom measurements with ibex, are consistent with the interstellar modulation of high-energy (tera-electron volts, tev) cosmic rays and diffusive propagation from s ...201424526313
influences of mating group composition on the behavioral time-budget of male and female alpine ibex (capra ibex) during the rut.during the rut, polygynous ungulates gather in mixed groups of individuals of different sex and age. group social composition, which may vary on a daily basis, is likely to have strong influences on individual's time-budget, with emerging properties at the group-level. to date, few studies have considered the influence of group composition on male and female behavioral time budget in mating groups. focusing on a wild population of alpine ibex, we investigated the influence of group composition ( ...201424416453
european springtime temperature synchronises ibex horn growth across the eastern swiss alps.direct effects of climate change on animal physiology, and indirect impacts from disruption of seasonal synchrony and breakdown of trophic interactions are particularly severe in arctic and alpine ecosystems. unravelling biotic from abiotic drivers, however, remains challenging because high-resolution animal population data are often limited in space and time. here, we show that variation in annual horn growth (an indirect proxy for individual performance) of 8043 male alpine ibex (capra ibex) o ...201424341995
reliability of an elisa test for diagnosing oestrosis in iberian ibex.oestrosis is one of the most prevalent parasitosis affecting the iberian ibex, capra pyrenaica . to date, both the diagnosis of oestrosis and the determination of the intensity of parasitism require the use of invasive methods (necropsy), which necessarily limit research possibilities. we analyzed the immune humoral response (igm and igg) against oestrus ovis l. excretory/secretory larval antigens in 32 sera taken from iberian ibex from the sierra nevada natural space (southern spain). three ant ...201424299554
the use of radio-collars for monitoring wildlife diseases: a case study from iberian ibex affected by sarcoptes scabiei in sierra nevada, spain.wildlife radio tracking has gained popularity during the recent past. ecologists and conservationists use radio-collars for different purposes: animal movement monitoring, home range, productivity, population estimation, behaviour, habitat use, survival, and predator-prey interaction, among others. the aim of our present study is to highlight the application of radio-collars for wildlife diseases monitoring. the spread of wildlife diseases and the efficacy of management actions for controlling t ...201323965311
alpine ibex males grow large horns at no survival cost for most of their lifetime.large horns or antlers require a high energy allocation to produce and carry both physiological and social reproductive costs. following the principle of energy allocation that implies trade-offs among fitness components, growing large weapons early in life should thus reduce future growth and survival. evidence for such costs is ambiguous, however, partly because individual heterogeneity can counterbalance trade-offs. individuals with larger horns or antlers may be of better quality and thus ha ...201323774947
variation in lithic technological strategies among the neanderthals of gibraltar.the evidence for neanderthal lithic technology is reviewed and summarized for four caves on the rock of gibraltar: vanguard, beefsteak, ibex and gorham's. some of the observed patterns in technology are statistically tested including raw material selection, platform preparation, and the use of formal and expedient technological schemas. the main parameters of technological variation are examined through detailed analysis of the gibraltar cores and comparison with samples from the classic mouster ...201323762312
consequences of snowy winters on male mating strategies and reproduction in a mountain ungulate.alternative mating tactics (amts) are intrasexual variants in mating behaviour of several species ranging from arthropods to mammals. male amts coexist between and within populations. in particular, male ungulates rarely adopt just one tactic throughout their lifetime. tactics commonly change according to internal factors (age, body size, condition) and external conditions (weather, resources, predation, animal density). however, the influence of weather has not yet been investigated in upper ve ...201323669063
photoperiod and melatonin treatments for controlling sperm parameters, testicular and accessory sex glands size in male iberian ibex: a model for captive mountain ruminants.this study examines whether photoperiod and/or melatonin treatments can improve sperm variables outside the breeding season in the iberian ibex-a model species for wild mountain ruminants-thus helping in the collection of high quality sperm beyond the normal breeding season for depositing in genetic resource banks. adult iberian ibex males (n=17) were divided into four treatment groups: (1) controls under the natural photoperiod (control group; n=4), (2) treatment with melatonin implants on dece ...201323664101
approximate bayesian computation for modular inference problems with many parameters: the example of migration rates.we propose a two-step procedure for estimating multiple migration rates in an approximate bayesian computation (abc) framework, accounting for global nuisance parameters. the approach is not limited to migration, but generally of interest for inference problems with multiple parameters and a modular structure (e.g. independent sets of demes or loci). we condition on a known, but complex demographic model of a spatially subdivided population, motivated by the reintroduction of alpine ibex (capra ...201323301635
birds of a feather: neanderthal exploitation of raptors and corvids.the hypothesis that neanderthals exploited birds for the use of their feathers or claws as personal ornaments in symbolic behaviour is revolutionary as it assigns unprecedented cognitive abilities to these hominins. this inference, however, is based on modest faunal samples and thus may not represent a regular or systematic behaviour. here we address this issue by looking for evidence of such behaviour across a large temporal and geographical framework. our analyses try to answer four main quest ...201223029321
a novel approach for choosing summary statistics in approximate bayesian computation.the choice of summary statistics is a crucial step in approximate bayesian computation (abc). since statistics are often not sufficient, this choice involves a trade-off between loss of information and reduction of dimensionality. the latter may increase the efficiency of abc. here, we propose an approach for choosing summary statistics based on boosting, a technique from the machine-learning literature. we consider different types of boosting and compare them to partial least-squares regression ...201222960215
effect of acepromazine and haloperidol in male iberian ibex (capra pyrenaica) captured by box-trap.short-acting neuroleptic drugs are used to prevent adverse effects of stress in wildlife. we compared the effect of acepromazine and haloperidol in iberian ibex (capra pyrenaica) captured with box-traps. we captured 23 male iberian ibex at the national game reserve of ports de tortosa i beseit, northeastern spain, march 2003-june 2005. seven animals received 0.1 mg/kg of acepromazine maleate, eight received 0.33 mg/kg of haloperidol and eight animals acted as controls. clinical, hematologic, and ...201222740543
role of testosterone and photoperiod on seasonal changes in horn growth and sperm variables in the iberian ibex: a model for polygynous wild bovids.this work examines the effect of testosterone secretion and photoperiod on seasonal changes in horn growth and sperm variables in the iberian ibex (capra pyrenaica), here used as a model for polygynous wild bovids. the hypothesis that high levels of testosterone provide an endocrine signal that inhibits horn growth in autumn was tested by assessing the effect of cyproterone acetate (ca), an anti-androgen, administered in october - coinciding with the period of natural increases in plasma testost ...201222645301
the heliosphere's interstellar interaction: no bow shock.as the sun moves through the local interstellar medium, its supersonic, ionized solar wind carves out a cavity called the heliosphere. recent observations from the interstellar boundary explorer (ibex) spacecraft show that the relative motion of the sun with respect to the interstellar medium is slower and in a somewhat different direction than previously thought. here, we provide combined consensus values for this velocity vector and show that they have important implications for the global int ...201222582011
standardizing the double-observer survey method for estimating mountain ungulate prey of the endangered snow leopard.mountain ungulates around the world have been threatened by illegal hunting, habitat modification, increased livestock grazing, disease and development. mountain ungulates play an important functional role in grasslands as primary consumers and as prey for wild carnivores, and monitoring of their populations is important for conservation purposes. however, most of the several currently available methods of estimating wild ungulate abundance are either difficult to implement or too expensive for ...201222231373
coprological analyses on apparently healthy alpine ibex (capra ibex ibex) from two swiss colonies.to provide baseline parasitological data for health surveillance in free-ranging alpine ibex (capra ibex ibex), we assessed the endoparasite population and level of parasitism in apparently healthy ibex. faecal samples from 148 ibex were collected between 2006 and 2008 in two different swiss ibex colonies. they were analysed by coprology, including combined sedimentation/flotation method, sedimentation method, baermann funnel technique and ziehl-neelsen staining. gastrointestinal parasites and l ...201222119388
seasonal variation in reproductive physiological status in the iberian ibex (capra pyrenaica) and its relationship with sperm freezability.the present work examines the relationship between seasonal changes in testicular function, accessory gland size, and horn growth in iberian ibexes, as well as the relationship between these changes and the resistance of ibex spermatozoa to freezing-thawing. the size of the bulbourethral glands and seminal vesicles showed pronounced monthly variation (p < 0.001), which was correlated positively with the plasma testosterone concentration (p < 0.001) and scrotal circumference (p < 0.001). the size ...201121855981
global observations of the interstellar interaction from the interstellar boundary explorer (ibex).the sun moves through the local interstellar medium, continuously emitting ionized, supersonic solar wind plasma and carving out a cavity in interstellar space called the heliosphere. the recently launched interstellar boundary explorer (ibex) spacecraft has completed its first all-sky maps of the interstellar interaction at the edge of the heliosphere by imaging energetic neutral atoms (enas) emanating from this region. we found a bright ribbon of ena emission, unpredicted by prior models or th ...200919833923
structures and spectral variations of the outer heliosphere in ibex energetic neutral atom maps.the interstellar boundary explorer (ibex) has obtained all-sky images of energetic neutral atoms emitted from the heliosheath, located between the solar wind termination shock and the local interstellar medium (lism). these flux maps reveal distinct nonthermal (0.2 to 6 kilo-electron volts) heliosheath proton populations with spectral signatures ordered predominantly by ecliptic latitude. the maps show a globally distributed population of termination-shock-heated protons and a superimposed ribbo ...200919833918
direct observations of interstellar h, he, and o by the interstellar boundary explorer.neutral gas of the local interstellar medium flows through the inner solar system while being deflected by solar gravity and depleted by ionization. the dominating feature in the energetic neutral atom interstellar boundary explorer (ibex) all-sky maps at low energies is the hydrogen, helium, and oxygen interstellar gas flow. the he and o flow peaked around 8 february 2009 in accordance with gravitational deflection, whereas h dominated after 26 march 2009, consistent with approximate balance of ...200919833917
width and variation of the ena flux ribbon observed by the interstellar boundary explorer.the dominant feature in interstellar boundary explorer (ibex) sky maps of heliospheric energetic neutral atom (ena) flux is a ribbon of enhanced flux that extends over a broad range of ecliptic latitudes and longitudes. it is narrow (approximately 20 degrees average width) but long (extending over 300 degrees in the sky) and is observed at energies from 0.2 to 6 kilo-electron volts. we demonstrate that the flux in the ribbon is a factor of 2 to 3 times higher than that of the more diffuse, globa ...200919833916
comparison of interstellar boundary explorer observations with 3d global heliospheric models.simulations of energetic neutral atom (ena) maps predict flux magnitudes that are, in some cases, similar to those observed by the interstellar boundary explorer (ibex) spacecraft, but they miss the ribbon. our model of the heliosphere indicates that the local interstellar medium (lism) magnetic field (b(lism)) is transverse to the line of sight (los) along the ribbon, suggesting that the ribbon may carry its imprint. the force-per-unit area on the heliopause from field line draping and the lism ...200919833915
a mass analysis technique using coincidence measurements from the interstellar boundary explorer-hi (approximately 0.3- approximately 6 kev) detector.nasa's interstellar boundary explorer (ibex) mission, scheduled to launch in october 2008, will make the first observations of charge exchange energetic neutral atoms (enas) produced near the edge of the heliosphere. ibex will measure these enas with two ultra-high sensitivity, single-pixel ena sensors in the energy range of approximately 0.01- approximately 2 kev (ibex-lo) and approximately 0.3- approximately 6 kev (ibex-hi), respectively. the primary purpose of ibex is to measure hydrogen enas ...200819044461
computer programs: onesamp: a program to estimate effective population size using approximate bayesian computation.the estimation of effective population size from one sample of genotypes has been problematic because most estimators have been proven imprecise or biased. we developed a web-based program, onesamp that uses approximate bayesian computation to estimate effective population size from a sample of microsatellite genotypes. onesamp requires an input file of sampled individuals' microsatellite genotypes along with information about several sampling and biological parameters. onesamp provides an estim ...200821585773
the ion-optical prototype of the low energy neutral atom sensor of the interstellar boundary explorer mission (ibex).the direct measurement of the energetic neutral atoms originating from the heliospheric termination shock and beyond as well as neutral interstellar gas penetrating into the heliosphere requires a very sensitive neutral particle imaging instrument in the energy range of 10-1000 ev. we present the development of the prototype of the low energy sensor for the interstellar boundary explorer (ibex) mission: ibex-lo is a neutral particle mass spectrometer dedicated to the measurement of energetic neu ...200718163739
differences in biomarkers of type ii collagen in atrophic and hypertrophic osteoarthritis of the hip: implications for the differing pathobiologies.cartilage destruction in osteoarthritis (oa) involves the excessive degradation and increased synthesis of cartilage matrix macromolecules including type ii collagen (cii) and proteoglycans. the lack of osteophytes (atrophic form of oa) has been shown to be a disease severity factor in hip oa. since osteophyte formation involves endochondral ossification and a cartilage intermediate, atrophic oa may also exhibit differences in cartilage turnover compared to hypertrophic oa. cartilage serum bioma ...200717055306
infrared balloon experiment: improved instrumental configuration and assessment of instrument performance.during the 2002 environmental satellite envisat mid-latitude validation campaign, a new upgraded configuration of the infrared balloon experiment (ibex) fourier transform spectrometer, which had its first flight in 1978, performed a stratospheric balloon flight across the mediterranean sea. among the substantial upgrades made to the instrument, the use of photon-noise-limited detectors permitted us to reach the theoretical limits in terms of signal-to-noise ratio. also, important modifications w ...200616512548
an evaluation of the application of infrared thermal imaging to the tele-diagnosis of sarcoptic mange in the spanish ibex (capra pyrenaica).the application of infrared thermal imaging to the diagnosis of sarcoptic mange in the wild spanish ibex (capra pyrenaica) was evaluated. seventy-three ibexes (35 males, 38 females) of varying ages were studied. each animal was observed using conventional binoculars (ot) to detect lesions characteristic of mange. infrared thermography (ir) was then performed and the resultant image judged negative or positive. the distance from the thermograph to the animal was measured, and the animal killed. s ...200212383630
post-cambrian trilobite diversity and evolutionary faunasa cluster analysis of the stratigraphic distribution of all ordovician trilobite families, based on a comprehensive taxonomic database, identified two major faunas with disjunct temporal diversity trends. the ibex fauna behaved as a cohort, declining through the ordovician and disappearing at the end-ordovician mass extinction. in contrast, the whiterock fauna radiated rapidly during the middle ordovician and gave rise to all post-ordovician trilobite diversity. its pattern of diversification ma ...19989632387

immobilization of captive nubian ibex (capra nubiana) with butorphanol-midazolam-medetomidine or butorphanol-azaperone-medetomidine and atipamezole reversal.seventeen captive nubian ibex (capra nubiana) were immobilized for transportation and/or hoof trimming, deworming, and vaccinations. of these, 11 were immobilized with a combination of butorphanol (0.13±0.03 mg/kg), midazolam (0.13±0.03 mg/kg), and medetomidine (0.13±0.03 mg/kg) (bmm), and 6 were immobilized with a combination of butorphanol (0.11±0.03 mg/kg), azaperone (0.22±0.06 mg/kg), and medetomidine (0.11±0.03 mg/kg) (bam) by intramuscular injection. induction and recovery times were recor ...201526056882
nutritional ecology of dimorphic herbivores: digestion and passage rates in nubian ibex.we compared forage digestion and passage rates among three groups of nubian ibex (capra ibex nubiana) - mature males, non-lactating females, and lactating females - to test hypotheses relating intraspecific digestive ability to body mass and reproduction costs. we hypothesized that large males (60 kg) would exhibit longer forage retention times and more complete digestion of fermentable cell walls than adult females (23 kg). we tested these predictions by measuring digestion and retention of a g ...199628307302
terrain preferences in the play behavior of siberian ibex kids (capra ibex sibirica).play behavior was studied in a captive group of siberian ibex at the chicago zoological park. the hypothesis that physical training effects were at least partially responsible for the evolution of play in this species was tested by noting the amounts of play which occurred on flat and on sloped surfaces. the kids showed a clear preference for play on sloped terrain, even though this choice resulted in considerably greater risks. the danger involved in highly active locomotor play performed on st ...1977602463
postepizootic persistence of asymptomatic mycoplasma conjunctivae infection in iberian ibex.the susceptibility of the iberian ibex (capra pyrenaica) to mycoplasma conjunctivae ocular infection and the changes in their interaction over time were studied in terms of clinical outcome, molecular detection, and igg immune response in a captive population that underwent a severe infectious keratoconjunctivitis (ikc) outbreak. mycoplasma conjunctivae was detected in the iberian ibex, coinciding with the ikc outbreak. its prevalence had a decreasing trend in 2013 that was consistent with the c ...201728526790
identification and characterization of mycoplasma feriruminatoris sp. nov. strains isolated from alpine ibex: a 4th species in the mycoplasma mycoides cluster hosted by non-domesticated ruminants?the genus mycoplasma, a group of free-living, wall-less prokaryotes includes more than 100 species of which dozens are primary pathogens of humans and domesticated animals. mycoplasma species isolated from wildlife are rarely investigated but could provide a fuller picture of the evolutionary history and diversity of this genus. in 2013 several isolates from wild caprinae were tentatively assigned to a new species, mycoplasma (m.) feriruminatoris sp. nov., characterized by an unusually rapid gro ...201728611743
monitoring of schmallenberg virus in spanish wild artiodactyls, 2006-2015.schmallenberg disease is an emerging disease that affects domestic and wild ruminants in europe. an epidemiological survey was carried out to assess exposure to schmallenberg virus (sbv) in wild artiodactyls in spain between 2006 and 2015. a total of 1751 sera from wild artiodactyls, including 1066 red deer, 304 fallow deer, 192 mouflon, 109 wild boar, 49 roe deer and 31 spanish ibex were tested for antibodies against sbv by elisa and confirmed by virus neutralization test. sbv was not detected ...201728813443
revision of the alycaeidae of china, laos and vietnam (gastropoda: cyclophoroidea) i: the genera <i>dicharax</i> and <i>metalycaeus</i>.this is the first part of the revision of the alycaeidae of china, laos and vietnam. here we revise the species hitherto classified in chamalycaeus möllendorff, 1897 (genera dicharax and metalycaeus in this study). we show that no chamalycaeus live in the region, and the alycaeid species of the investigated region can be classified into five genera: alycaeus baird, 1850, dicharax kobelt & möllendorff, 1900, dioryx benson, 1859, metalycaeus pilsbry, 1900 and pincerna preston, 1907. we propose dio ...201729242453
histopathology, microbiology and the inflammatory process associated with sarcoptes scabiei infection in the iberian ibex, capra pyrenaica.sarcoptic mange has been identified as the most significant infectious disease affecting the iberian ibex (capra pyrenaica). despite several studies on the effects of mange on ibex, the pathological and clinical picture derived from sarcoptic mange infestation is still poorly understood. to further knowledge of sarcoptic mange pathology, samples from ibex were evaluated from histological, microbiological and serological perspectives.201729202802
sarcoptes scabiei alters follicular dynamics in female iberian ibex through a reduction in body weight.normal development of the ovarian cycle is a key factor in ensuring female reproductive success. sarcoptes scabiei has been shown to induce changes in host physiology, although the effects of this mite on the female reproductive cycle are still unknown. in an attempt to clarify this issue, the number of ovarian structures (primary follicles, secondary follicles, graaf follicles, corpus luteum and corpus albicans) in female iberian ibex (capra pyrenaica) affected by sarcoptic mange was explored b ...201728807285
evaluation of oxidant/antioxidant balance in iberian ibex (capra pyrenaica) experimentally infested with sarcoptes scabiei.oxidative stress (os) is an imbalance between radical-generating and radical scavenging activity, resulting in oxidation products and tissue damage. although some studies have been done in other species, there is a lack of information about the oxidative/antioxidant status in the iberian ibex (capra pyrenaica) affected by sarcoptic mange. to clarify this fact, albumin, catalase (cat), glutathione peroxidase (gsh-px), superoxide dismutase (sod), paraoxonase-1 (pon-1), glutathione reductase (gr), ...201728606327
linking seasonal home range size with habitat selection and movement in a mountain ungulate.space use by animals is determined by the interplay between movement and the environment, and is thus mediated by habitat selection, biotic interactions and intrinsic factors of moving individuals. these processes ultimately determine home range size, but their relative contributions and dynamic nature remain less explored. we investigated the role of habitat selection, movement unrelated to habitat selection and intrinsic factors related to sex in driving space use and home range size in iberia ...201829318021
population genomics analyses of european ibex species show lower diversity and higher inbreeding in reintroduced populations.restoration of lost species ranges to their native distribution is key for the survival of endangered species. however, reintroductions often fail and long-term genetic consequences are poorly understood. alpine ibex (capra ibex) are wild goats that recovered from <100 individuals to ~50,000 within a century by population reintroductions. we analyzed the population genomic consequences of the alpine ibex reintroduction strategy. we genotyped 101,822 genomewide single nucleotide polymorphism loci ...201829387150
predicting herbivore faecal nitrogen using a multispecies near-infrared reflectance spectroscopy calibration.optimal management of free-ranging herbivores requires the accurate assessment of an animal's nutritional status. for this purpose 'near-infrared reflectance spectroscopy' (nirs) is very useful, especially when nutritional assessment is done through faecal indicators such as faecal nitrogen (fn). in order to perform an nirs calibration, the default protocol recommends starting by generating an initial equation based on at least 50-75 samples from the given species. although this protocol optimis ...201728453544
toxoplasma gondii in sympatric domestic and wild ungulates in the mediterranean ecosystem.toxoplasma gondii is a zoonotic protozoan of worldwide distribution. the present study provides information on risk factors affecting t. gondii infection in domestic and free-ranging wild ungulates sharing habitats in mediterranean ecosystems in spain. serum samples from 482 extensively reared domestic ruminants and 2351 wild ungulates were tested for t. gondii antibodies using the modified agglutination test (mat, cut-off 1:25). toxoplasma gondii seroprevalence was 41.2% of 194 sheep, 18.6% of ...201829344801

sociospatial structure explains marked variation in brucellosis seroprevalence in an alpine ibex population.in a context of (re)emerging infectious diseases with wildlife reservoirs, understanding how animal ecology shapes epidemiology is a key issue, particularly in wild ungulates that share pathogens with domestic herbivores and have similar food requirements. for the first time in europe, brucellosis (brucella melitensis), a virulent zoonosis, persisted in an alpine ibex (capra ibex) population and was transmitted to cattle and humans. to better understand disease dynamics, we investigated the rela ...201729142204
on the possible role of ticks in the eco-epidemiology of coxiella burnetii in a mediterranean ecosystem.ruminant livestock is the main reservoir of coxiella burnetii (cb), but little is known about the role of wildlife and ticks in its epidemiology. the iberian ibex (capra pyrenaica, schinz 1838) population of "ports de tortosa i beseit" (ne spain) suffers intense tick infestations and low reproduction rates. this study aims to (1) assess the relationship between infection in ibexes (detection of serum antibodies and/or of cb dna in tissues) and cb dna presence in ticks hosted by the same ibexes; ...201829478883
the diagnostic activity on wild animals through the description of a model case report (caseous lymphadenitis bycorynebacterium pseudotuberculosisassociated withpasteurellaspp and parasites infection in an alpine ibex -capra ibex).the diagnostic activity on wild animals implies a hard laboratory protocol where multiple disciplines, from biology to pathological anatomy until the biotechnological techniques, must be integrated to establish the causes of death. to demonstrate these concepts, the analytical approach adopted for an alpine ibex (capra ibex) found dead in a mountain area of north western italy was described. the animal showed sub-costal and lymph nodes collections of green-yellow pus, fibrinous pleuropneumonia a ...201729392118
effect of two cooling protocols on the post-thaw characteristics of iberian ibex sperms.the rate at which lethal intracellular ice forms during sperm cryopreservation is highly dependent on the cooling protocol. the present work compares two cooling protocols for use with iberian ibex (capra pyrenaica) sperm by assessing the effects on the motility, viability, and size of frozen-thawed sperm cells. ejaculates, obtained from six adult ibex males via transrectal, ultrasound-guided massage of the accessory sex glands plus electroejaculation if necessary, were cooled via either 1) prot ...201829352980
