shiga toxin subtypes associated with shiga toxin-producing escherichia coli strains isolated from red deer, roe deer, chamois, and ibex.a total of 52 shiga toxin-producing escherichia coli (stec) strains, isolated from fecal samples of six ibex, 12 chamois, 15 roe deer, and 19 red deer were further characterized by subtyping the stx genes, examining strains for the top nine serogroups and testing for the presence of eae and ehxa. eleven of the 52 strains belonged to one of the top nine stec o groups (o26, o45, o91, o103, o111, o113, o121, o145, and o157). eight stec strains were of serogroup o145, two strains of serogroup o113, ...201222891940
shedding of foodborne pathogens and microbial carcass contamination of hunted wild ruminants.to assess the shedding of selected bacterial foodborne pathogens, fecal samples from 239 hunted wild red deer, roe deer, chamois, and ibex were examined. all samples tested negative for salmonella spp. and l. monocytogenes, but other listeria species were occasionally found. of the 239 fecal samples, 32.6% tested positive for stx (shiga toxins), 6.7% for eae (intimin) and 13.8% for both stx and eae genes. among the 56 isolated shiga toxin-producing escherichia coli (stec) strains, 44.6% harbored ...201222503394
detection of antibodies in wild ruminants to evaluate exposure to liver trematodes.wild ruminants sharing pastures with domestic livestock are at risk of infection by liver trematodes. detection of antibodies provides a very useful tool to gain more knowledge about the distribution of these parasites. non-lethal methods are strongly encouraged for the analysis of the risk of infection among wild ruminants. a seroepidemiological survey was conducted to analyze exposure to hepatic trematodes ( fasciola hepatica and dicrocoelium dendriticum ) in wild ruminants from southern spain ...201222414166
emergence of atypical mycoplasma agalactiae strains harboring a new prophage and associated with an alpine wild ungulate mortality episode.the bacterium mycoplasma agalactiae is responsible for contagious agalactia (ca) in small domestic ruminants, a syndrome listed by the world organization for animal health and responsible for severe damage to the dairy industry. recently, we frequently isolated this pathogen from lung lesions of ibexes during a mortality episode in the french alps. this situation was unusual in terms of host specificity and tissue tropism, raising the question of m. agalactiae emergence in wildlife. to address t ...201222522685
occurrence, quantification, and genotyping of mycoplasma conjunctivae in wild caprinae with and without infectious keratoconjunctivitis.mycoplasma conjunctivae, the causative agent of infectious keratoconjunctivitis (ikc), was recently detected in asymptomatic alpine ibex (capra ibex ibex). this suggested that an external source of infection may not be required for an ikc outbreak in wildlife but might be initiated by healthy carriers, which contradicted previous serologic investigations in chamois. our aims were to 1) assess the prevalence of m. conjunctivae among asymptomatic ibex and alpine chamois (rupicapra rupicapra rupica ...201222740528
mycoplasma feriruminatoris sp. nov., a fast growing mycoplasma species isolated from wild caprinae.five mycoplasma strains from wild caprinae were analyzed: four from alpine ibex (capra ibex) which died at the berlin zoo between 1993 and 1994, one from a rocky mountain goat collected in the usa prior to 1987. these five strains represented a population different from the populations belonging to the 'mycoplasma mycoides cluster' as tested using multi locus sequence typing, matrix-assisted laser desorption/ionization time of flight mass spectrometry analysis and dna-dna hybridization. analysis ...201324016869
methicillin resistant staphylococcus aureus (mrsa) carriage in different free-living wild animal species in spain.methicillin-resistant staphylococcus aureus (mrsa) is a life-threatening pathogen in humans and its presence in animals is a public health concern. the aim of this study was to measure the prevalence of mrsa in free-living wild animals. samples from red deer (n=273), iberian ibex (n=212), eurasian griffon vulture (n=40) and wild boar (n=817) taken from different areas in spain between june 2008 and november 2011 were analyzed. characterization of the isolates was performed by spa typing, multi-l ...201323846031
pathogenic yersinia enterocolitica o:3 isolated from a hunted wild alpine ibex.occurrence of yersinia spp. in wild ruminants was studied and the strains were characterized to get more information on the epidemiology of enteropathogenic yersinia in the wildlife. in total, faecal samples of 77 red deer, 60 chamois, 55 roe deer and 27 alpine ibex were collected during 3 months of the hunting season in 2011. the most frequently identified species was y. enterocolitica found in 13%, 10%, 4% and 2% of roe deer, red deer, alpine ibex and chamois, respectively. interestingly, one ...201322697252
occurrence of mycobacterium avium subsp. paratuberculosis in fecal samples of hunted deer, chamois and ibex in switzerland. 201323985097
survey of bluetongue virus infection in free-ranging wild ruminants in switzerland.in 2006, bluetongue virus serotype 8 (btv-8) was detected for the first time in central europe. measures to control the infection in livestock were implemented in switzerland but the question was raised whether free-ranging wildlife could be a maintenance host for btv-8. furthermore toggenburg orbivirus (tov), considered as a potential 25th btv serotype, was detected in 2007 in domestic goats in switzerland and wild ruminants were considered a potential source of infection. to assess prevalences ...201323941229
mycoplasma conjunctivae in domestic small ruminants from high mountain habitats in northern spain.infectious keratoconjunctivitis (ikc) is a clinical condition affecting eyes of domestic and wild caprinae worldwide, and mycoplasma conjunctivae is considered the primary causative agent of ikc in sheep, goats and wild caprinae. domestic ruminants from high mountain habitats share grazing areas with wild mountain ungulates, such as chamois (rupicapra spp.), alpine ibex (capra ibex) and european mouflon (ovis aries musimon), and domestic sheep seem to act as m. conjunctivae reservoir. in this st ...201324330682
antimicrobial resistance in indicator escherichia coli isolates from free-ranging livestock and sympatric wild ungulates in a natural environment (northeastern spain).antimicrobial resistance was assessed in indicator escherichia coli isolates from free-ranging livestock and sympatric wild boar (sus scrofa) and iberian ibex (capra pyrenaica) in a national game reserve in northeastern spain. the frequency of antimicrobial resistance was low (0% to 7.9%). however, resistance to an extended-spectrum cephalosporin and fluoroquinolones was detected.201323892753
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
cryopreservation of aoudad (ammotragus lervia sahariensis) sperm obtained by transrectal ultrasound-guided massage of the accessory sex glands and electroejaculation.this study examines (1) the effectiveness of transrectal, ultrasound-guided massage of the accessory sex glands (tumasg) combined with electroejaculation for obtaining aoudad (ammotragus lervia sahariensis) sperm samples for cryopreservation, and (2) the effectiveness of a tris-citric acid-glucose-based medium (tcg; usually used for freezing ibex sperm) and a tes-tris-glucose-based medium (ttg; typically used in the cryopreservation of mouflon sperm) as sperm extenders. after tumasg, just one to ...201323158213
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
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
strong artificial selection in domestic mammals did not result in an increased recombination rate.recombination rates vary in intensity and location at the species, individual, sex and chromosome levels. despite the fundamental biological importance of this process, the selective forces that operate to shape recombination rate and patterns are unclear. domestication offers a unique opportunity to study the interplay between recombination and selection. in domesticates, intense selection for particular traits is imposed on small populations over many generations, resulting in organisms that d ...201425414125
prey preferences of the snow leopard (panthera uncia): regional diet specificity holds global significance for conservation.the endangered snow leopard is a large felid that is distributed over 1.83 million km(2) globally. throughout its range it relies on a limited number of prey species in some of the most inhospitable landscapes on the planet where high rates of human persecution exist for both predator and prey. we reviewed 14 published and 11 unpublished studies pertaining to snow leopard diet throughout its range. we calculated prey consumption in terms of frequency of occurrence and biomass consumed based on 1 ...201424533080
carriage of staphylococcus aureus by free-living wild animals in spain.the presence of methicillin-susceptible staphylococcus aureus (mssa) was analyzed in different free-living wild animals to assess the genetic diversity and predominant genotypes on each animal species. samples were taken from the skin and/or nares, and isolates were characterized by spa typing, multilocus sequence typing (mlst) and antimicrobial susceptibility testing. the proportion of mssa carriers were 5.00, 22.93, 19.78, and 17.67% in eurasian griffon vulture, iberian ibex, red deer, and wil ...201424907325
babesia spp. in european wild ruminant species: parasite diversity and risk factors for infection.babesia are tick-borne parasites that are increasingly considered as a threat to animal and public health. we aimed to assess the role of european free-ranging wild ruminants as maintenance mammalian hosts for babesia species and to determine risk factors for infection. edta blood was collected from 222 roe deer (capreolus c. capreolus), 231 red deer (cervus e. elaphus), 267 alpine chamois (rupicapra r. rupicapra) and 264 alpine ibex (capra i. ibex) from all over switzerland and analysed by pcr ...201424925474
brucella melitensis in france: persistence in wildlife and probable spillover from alpine ibex to domestic animals.bovine brucellosis is a major zoonosis, mainly caused by brucella abortus, more rarely by brucella melitensis. france has been bovine brucellosis officially-free since 2005 with no cases reported in domestic/wild ruminants since 2003. in 2012, bovine and autochthonous human cases due to b. melitensis biovar 3 (bmel3) occurred in the french alps. epidemiological investigations implemented in wild and domestic ruminants evidenced a high seroprevalence (>45%) in alpine ibex (capra ibex); no cases w ...201424732322
introgression from domestic goat generated variation at the major histocompatibility complex of alpine ibex.the major histocompatibility complex (mhc) is a crucial component of the vertebrate immune system and shows extremely high levels of genetic polymorphism. the extraordinary genetic variation is thought to be ancient polymorphisms maintained by balancing selection. however, introgression from related species was recently proposed as an additional mechanism. here we provide evidence for introgression at the mhc in alpine ibex (capra ibex ibex). at a usually very polymorphic mhc exon involved in pa ...201424945814
management of a caseous lymphadenitis outbreak in a new iberian ibex (capra pyrenaica) stock reservoir.in 2010, an iberian ibex (capra pyrenaica hispanica) stock reservoir was established for conservation purposes in north-eastern spain. eighteen ibexes were captured in the wild and housed in a 17 hectare enclosure. once in captivity, a caseous lymphadenitis (cla) outbreak occurred and ibex handlings were carried out at six-month intervals between 2010 and 2013 to perform health examinations and sampling. treatment with a bacterin-based autovaccine and penicillin g benzatine was added during the ...201425492129
finding a robust strain for biomethanation: anaerobic fungi (neocallimastigomycota) from the alpine ibex (capra ibex) and their associated methanogens.anaerobic fungi occupy the rumen and digestive tract of herbivores, where they play an important role in enzymatic digestion of lignocellulosic and cellulosic substrates, i.e. organic material that their hosts are unable to decompose on their own. in this study we isolated anaerobic fungi from a typical alpine herbivore, the alpine ibex (c. ibex). three fungal strains, either as pure culture (st2) or syntrophic co-culture with methanogens (st3, st4) were successfully obtained and morphologically ...201424384307
shedding of clostridium difficile pcr ribotype 078 by zoo animals, and report of an unstable metronidazole-resistant isolate from a zebra foal (equus quagga burchellii).clostridium difficile is an emerging and potentially zoonotic pathogen, but its prevalence in most animal species, including exhibition animals, is currently unknown. in this study we assessed the prevalence of faecal shedding of c. difficile by zoo animals, and determined the ribotype, toxin profile and antimicrobial susceptibility of recovered isolates. a total of 200 samples from 40 animal species (36.5% of which came from plains zebra, equus quagga burchellii) were analysed. c. difficile was ...201424467928
taenia multiceps brain cyst removal in two wild nubian ibex (capra nubianas).two wild adult nubian ibex (capra nubiana) were captured and admitted to the hebrew university veterinary teaching hospital with various neurologic signs, including alerted mentation, head tilt, and pathologic nystagmus. the lesion in the central nervous system was localized to the forebrain in one ibex and to the cerebellum of the other. both ibex's were diagnosed with brain cyst using computed tomography (ct). craniectomy was performed to remove the cysts, and both animals returned to their na ...201424712185
lack of evidence of spill-over of salmonella enterica between cattle and sympatric iberian ibex (capra pyrenaica) from a protected area in catalonia, ne spain.salmonella enterica is a zoonotic agent of worldwide importance found in a wide range of wild hosts. however, its prevalence in many popular game species has never been assessed. iberian ibex (capra pyrenaica) is the main game caprinae of the iberian peninsula and around two thousand individuals are hunted every year for trophy or for home consumption. in this work, 313 iberian ibexes from the ports de tortosa i beseit national game reserve (ne spain) were tested for salmonella enterica in faece ...201423217161
prevalence of subtilase cytotoxin-encoding subab variants among shiga toxin-producing escherichia coli strains isolated from wild ruminants and sheep differs from that of cattle and pigs and is predominated by the new allelic variant subab2-2.subtilase cytotoxin (subab) is an ab5 toxin produced by shiga toxin (stx)-producing escherichia coli (stec) strains usually lacking the eae gene product intimin. three allelic variants of subab encoding genes have been described: subab1, located on a plasmid, subab2-1, located on the pathogenicity island se-pai and subab2-2 located in an outer membrane efflux protein (oep) region. subab is becoming increasingly recognized as a toxin potentially involved in human pathogenesis. ruminants and cattl ...201525488108
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

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
