effect of egg yolk concentration on cryopreserving spanish ibex (capra pyrenaica) epididymal spermatozoa. | tris-egg yolk based diluents provide adequate cryoprotection for the sperm of most wild species in which they have been tested. the objective of the current study was to evaluate various tris-based diluents containing different concentrations of egg yolk, for the fertilizing ability of epididymal spermatozoa of the spanish ibex (capra pyrenaica) after freezing and thawing. for this purpose, we used heterologous in vivo fertilization by intrauterine insemination of domestic goats (capra hircus). ... | 2006 | 16631249 |
horn quality and postmortem sperm parameters in spanish ibex (capra pyrenaica hispanica). | the horns are secondary sexual characteristics used by males of many ungulate species for intra-sexual fights during the rut. thus, the dominant males with most developed horns are naturally selected for reproduction. several studies have suggested that the quality of the horn, in many wild ruminants, may be correlated with semen quality. the aim of the present study was to determine whether inter-individual differences in levels of horn asymmetry and horn size are related to differences in sper ... | 2007 | 16846702 |
seroprevalence of neospora caninum in non-carnivorous wildlife from spain. | serum samples from 1034 non-carnivorous wildlife from spain were tested for antibodies to neospora caninum by competitive screening enzyme linked immunosorbent assay (elisa) and confirmed by an indirect fluorescent antibody test (ifat). high agreement was observed between results in both techniques (kappa value higher than 0.9). prevalences of n. caninum antibodies positive by both techniques were 11.8% of 237 red deer (cervus elaphus), 7.7% of 13 barbary sheep (ammotragus lervia), 6.1% of 33 ro ... | 2007 | 16962706 |
sarcoptic mange and metapodial development in growing male iberian ibex (capra pyrenaica). | the effect of mange (sarcoptes scabiei) on metapodial growth was studied in 24 uninfested and 16 infested male iberian ibex from sierra nevada national park (southern spain). our results show that infested ibex had smaller metatarsal bones, lower body weight, and a delayed rhythm of ossification, by about 1 year. we conclude that skeletal development and body weight in the iberian ibex are sensitive to sarcoptic mange. | 2007 | 17110041 |
horn growth related to testosterone secretion in two wild mediterranean ruminant species: the spanish ibex (capra pyrenaica hispanica) and european mouflon (ovis orientalis musimon). | seasonal variations in the horn development and testicular activity of the spanish ibex (capra pyrenaica hispanica) (n=6) and european mouflon (ovis orientalis musimon) (n=5) were monitored to determine the role of increasing testosterone concentration on the arrest of horn growth during the rutting season. marked seasonal variations in the rate of horn growth (p<0.01) and testicular activity (p<0.001) were seen in both species, although the magnitude and timing of these changes were different ( ... | 2007 | 17123755 |
predicting fluctuations of reintroduced ibex populations: the importance of density dependence, environmental stochasticity and uncertain population estimates. | 1. development of population projections requires estimates of observation error, parameters characterizing expected dynamics such as the specific population growth rate and the form of density regulation, the influence of stochastic factors on population dynamics, and quantification of the uncertainty in the parameter estimates. 2. here we construct a population prediction interval (ppi) based on bayesian state space modelling of future population growth of 28 reintroduced ibex populations in s ... | 2007 | 17302840 |

detection of mycoplasma conjunctivae in the eyes of healthy, free-ranging alpine ibex: possible involvement of alpine ibex as carriers for the main causing agent of infectious keratoconjunctivitis in wild caprinae. | mycoplasma conjunctivae is considered the major cause of infectious keratoconjunctivitis (ikc) in alpine ibex (capra i. ibex) and chamois (rupicapra r. rupicapra). while it is known that domestic sheep can act as healthy carriers for m. conjunctivae, this question has not been addressed in wild ungulates so far. in this study, bacteriological investigations and field observations were performed to assess whether free-ranging alpine ibex can be healthy carriers of m. conjunctivae. among 136 ibex ... | 2009 | 18834681 |
rumen protozoal diversity in the spanish ibex (capra pyrenaica hispanica) as compared with domestic goats (capra hircus). | rumen protozoal diversity in the spanish ibex (si) was studied in males (n=4), females (n=7) and young (n=4) from the maestrazgo (spain) and contrasted with domestic goats (n=3; dg) of the same region. there were no differences among si types in protozoal concentration or in the number of protozoal species. only protozoa from the genus entodinium were observed in si (seven species), the highest numbers corresponding to e. damae, e. ovibos and e. parvum. dg harboured threefold more species than s ... | 2009 | 18929470 |
temperature constraints on foraging behaviour of male alpine ibex (capra ibex) in summer. | in arctic and alpine environments, warm summer temperatures may force a reduction in foraging time of large herbivores, whose tolerance for heat is lower than for species adapted to warmer weather. we constructed time budgets for marked ibex (capra ibex) males over two summers to test whether warm temperatures constrained foraging behaviour and forced altitudinal migrations. as daily temperature and solar radiation increased, feeding activity was reduced at midday and evening, but increased in t ... | 2009 | 18987895 |
high prevalence of antibodies against chlamydiaceae and chlamydophila abortus in wild ungulates using two "in house" blocking-elisa tests. | few data are available on the prevalence and relevance of chlamydiae in wild mammals, and even fewer studies have been conducted to determine the prevalence of chlamydophila abortus in wildlife hosts, most probably due to the absence of suitable species-specific serological assays for testing sera from wild animals. in light of this, we have developed two in-house blocking-elisa tests for detection of antibodies against chlamydiaceae and c. abortus in wild ungulates, and analyzed the relationshi ... | 2009 | 19010612 |
first birth of an animal from an extinct subspecies (capra pyrenaica pyrenaica) by cloning. | two experiments have been performed to clone the bucardo, an extinct wild goat. the karyoplasts were thawed fibroblasts derived from skin biopsies, obtained and cryopreserved in 1999 from the last living specimen, a female, which died in 2000. cytoplasts were mature oocytes collected from the oviducts of superovulated domestic goats. oocytes were enucleated and coupled to bucardo's fibroblasts by electrofusion. reconstructed embryos were cultured for 36h or 7d and transferred to either spanish i ... | 2009 | 19167744 |
cryopreservation of spanish ibex (capra pyrenaica) sperm obtained by electroejaculation outside the rutting season. | the effectiveness of electroejaculation for obtaining spanish ibex sperm samples for freeze preserving outside the rutting season was evaluated-the aim being to optimise biological resources for the establishment of germplasm banks. the effect of different egg yolk concentrations (6% or 12%, v/v) in diluents of different buffer composition (tris-citric acid buffer or tes-tris buffer) on frozen-thawed samples of the above also investigated. experiments were undertaken with six ibex males in febru ... | 2009 | 19233455 |
the mycoplasma conjunctivae genome sequencing, annotation and analysis. | the mollicute mycoplasma conjunctivae is the etiological agent leading to infectious keratoconjunctivitis (ikc) in domestic sheep and wild caprinae. although this pathogen is relatively benign for domestic animals treated by antibiotics, it can lead wild animals to blindness and death. this is a major cause of death in the protected species in the alps (e.g., capra ibex, rupicapra rupicapra). | 2009 | 19534756 |
analysing the isotopic life history of the alpine ungulates capra ibex and rupicapra rupicapra rupicapra through their horns. | the horn of ungulate grazers offers a valuable isotopic record of their diet and environment. however, there have been no reports of the spatio-temporal variation of the isotopic composition of horns. we investigated patterns of carbon (delta(13)c) and nitrogen (delta(15)n) isotopic composition along and perpendicular to the horn axis in capra ibex and rupicapra rupicapra rupicapra to assess the effects of animal age, within-year (seasonal) and inter-annual variation, natural contamination and s ... | 2009 | 19575404 |
revival of extinct species using nuclear transfer: hope for the mammoth, true for the pyrenean ibex, but is it time for "conservation cloning"? | recent accomplishments in the fields of nuclear transfer and genomics, such as the cloned offspring production from frozen mouse cells, cryopreserved at not too low temperatures without cryoprotectors; or the sequencing of wooly mammoth genome, have opened the opportunity for the revival of extinct species. as expected, they are receiving a lot of publicity in the media and also scientific attention. furthermore, it was recently published the "revival" of the first extinct subspecie: the pyrenea ... | 2009 | 19594389 |
bronchopulmonary nematode infection of capra pyrenaica in the sierra nevada massif, spain. | the present investigation examined the prevalence and abundance of bronchopulmonary nematodes in 213 randomly hunted iberian ibexes (capra pyrenaica) (87 females and 126 males) in the sierra nevada mountain range in spain between 2003 and 2006. post mortem examination revealed an overall prevalence of 72% for adult nematodes (cystocaulus ocreatus 44%, muellerius capillaris 44%, protostrongylus sp. 40%, and dictyocaulus filaria 4%). the abundances were 13.45+/-3.97, 5.18+/-2.49, 6.36+/-2.16, and ... | 2009 | 19596519 |
a palaeolithic map from 13,660 calbp: engraved stone blocks from the late magdalenian in abauntz cave (navarra, spain). | an engraved block from the cave of abauntz is interpreted as a magdalenian map in which the actual surrounding landscape, including mountains, rivers, and ponds, is represented. some possible routes or avenues of access to different parts of the geography are also engraved on the landscape. the engraving seems to reproduce the meandering course of a river crossing the upper part of side a of the block, joined by two tributaries near two mountains. one of these is identical to the mountain that c ... | 2009 | 19625071 |
influence of recovery method and microbial contamination on the response to freezing-thawing in ibex (capra pyrenaica) epididymal spermatozoa. | the method of sperm recovery may influence the initial quality of sperm samples and their response to freezing-thawing. the aim of the present work was to compare two methods for collecting epididymal spermatozoa in order to improve the quality of recovered sperm and reduce possible contamination. testes were obtained from 23 legally hunted, adult ibex males. the sperm mass of the right epididymis was collected by small longitudinal and transverse cuts made in the cauda epididymidis. the sperm m ... | 2009 | 19786008 |
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 ... | 2009 | 19833923 |
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 ... | 2009 | 19833918 |
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 ... | 2009 | 19833917 |
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 ... | 2009 | 19833916 |
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 ... | 2009 | 19833915 |
a strong genetic footprint of the re-introduction history of alpine ibex (capra ibex ibex). | a population's neutral genetic variation is a composite of its size, degree of isolation and demographic history. bottlenecks and founder events increase genetic drift, leading to the loss of genetic variation and increased genetic differentiation among populations. gene flow has the opposite effects. thus, gene flow can override the genetic patterns caused by founder events. using 37 microsatellite loci, we investigated the effects of serial bottlenecks on genetic variation and differentiation ... | 2009 | 19912536 |
acute phase protein response in alpine ibex with sarcoptic mange. | the acute phase proteins (app) are a group of serum proteins that change their concentration in animals following external or internal challenges, such as infection, inflammation or stress. the concentrations of four apps, including serum amyloid a (saa), haptoglobin (hp), alpha(1)-acid glycoprotein (agp) and ceruloplasmin (cp) were determined in serum collected from healthy alpine ibexes (capra ibex) and ibexes with sarcoptes scabiei mange. primary structures of all four apps were determined by ... | 2010 | 20036058 |
the influence of washing spanish ibex (capra pyrenaica) sperm on the effects of cryopreservation in dependency of the photoperiod. | extenders containing low concentrations of egg yolk are recommended for cryopreserving ibex spermatozoa. however, the phylogenetic relationship of the spanish ibex (capra pyrenaica) with domestic goats suggests that phospholipases in the seminal plasma may have a negative effect on the response to freezing-thawing when egg yolk-based diluents are employed. the aim of the current work was to determine how seminal plasma removal from spanish ibex semen, collected by electroejaculation over a perio ... | 2010 | 20092881 |
effect of sexual segregation on host-parasite interaction: model simulation for abomasal parasite dynamics in alpine ibex (capraibex). | we investigated whether sexual segregation might affect parasite transmission and host dynamics, hypothesising that if males are the more heavily infected sex and more responsible for the transmission of parasite infections, female avoidance of males and the space they occupy could reduce infection rates. a mathematical model, simulating the interaction between abomasal parasites and a hypothetical alpine ibex (capraibex) host population composed of its two sexes, was developed to predict the ef ... | 2010 | 20430029 |

assisted reproduction in mediterranean wild ruminants: lessons from the spanish ibex (capra pyrenaica). | despite apparent progress in reproductive technology as applied to wild ruminants, the success achieved in terms of the number of offspring that become healthy adults has remained low. difficulties often arise through a lack of knowledge regarding appropriate cryopreservation techniques, and indeed through a lack of detailed information on the reproductive physiology of the species in question. the spanish ibex (capra pyrenaica) is a wild caprid found exclusively in the mountains of iberia; only ... | 2010 | 21755689 |
sarcoptes scabiei: specific immune response to sarcoptic mange in the iberian ibex capra pyrenaica depends on previous exposure and sex. | host acquired immunity is a critical factor that conditions the survival of parasites. nevertheless, there is a shortage of data concerning inter-individual immunological inequalities in wild mammals. sarcoptic mange is a widespread parasitosis that severely affects mammals such as the iberian ibex (capra pyrenaica). despite some work on the subject, the immune response to sarcoptic mange infestation is still a complex and poorly understood phenomenon. to improve knowledge of the host-sarcoptes ... | 2010 | 19857492 |
genetic variability of haemonchus contortus (nematoda: trichostrongyloidea) in alpine ruminant host species. | genetic variability of the ovine parasite haemonchus contortus from the alpine area was investigated using mitochondrial dna (nd4 gene), internal transcribed spacers 1 and 2 and microsatellites, in order to assess whether cross-transmission between domestic and wild ruminants occurs. the dataset was composed of 78 individual adult male h. contortus collected from chamois (rupicapra r. rupicapra), roe deer (capreolus capreolus), alpine ibex (capra ibex ibex), domestic goat (capra hircus) and shee ... | 2010 | 19889245 |
freezability of iberian ibex (capra pyrenaica) spermatozoa according to the glycerolization temperature and plasma testosterone concentration. | ibex spermatozoa can be successfully frozen using glycerolated media. however, no information is available regarding the most effective method of glycerol addition in this species. the aim of the present work was to evaluate the effect of the glycerolization temperature on the response to freezing-thawing of ibex spermatozoa collected by electroejaculation. the effect of the interaction glycerolization temperature x plasma testosterone concentration was also evaluated. the spermatozoa used in th ... | 2010 | 20654610 |

characterization of mycoplasma isolated from an ibex (capra ibex) suffering from keratoconjunctivitis in northern italy. | in 2005 a mycoplasma species was isolated from ocular-conjunctival swabs from an adult male alpine ibex (capra ibex) from the valle d'aosta region, northern italy. the animal suffered from bilateral ocular discharge with diffuse inflammation, severe corneal involvement of the left eye and mild corneal opacity of the right eye. histologic examination revealed a keratoconjunctivitis characterized by lymphocytic and plasmacellular infiltration. laboratory investigations of the isolate included cult ... | 2010 | 20966258 |
negative effect of the arthropod parasite, sarcoptes scabiei, on testes mass in iberian ibex, capra pyrenaica. | testes mass is a key factor in male reproductive success and is potentially exposed to so-called 'parasitic castration'. this is the result of the direct destruction or alteration of reproductive cell lineages (parasitic castration sensu stricto), or the indirect detrimental effects - for example, via body condition - on the ability of progenitors to produce or rear offspring (parasitic castration sensu lato). there are enormous gaps in our knowledge on the effects of parasites on the testes of ... | 2010 | 21074328 |
epidemiological surveillance of bluetongue virus serotypes 1, 4 and 8 in spanish ibex (capra pyrenaica hispanica) in southern spain. | a cross-sectional study was carried out to assess the prevalence and circulation of bluetongue virus (btv) in spanish ibexes (capra pyrenaica hispanica). a total of 770 sera samples, 380 blood samples and 34 spleen samples were collected between 2006 and 2009 in andalusia (southern spain), a region and time period with a wide circulation of btv in livestock. thirty-one out of 770 (4.0%; ci(95%): 2.6-5.4) sera samples analyzed by elisa showed antibodies against btv. twenty-four out of 31 seroposi ... | 2010 | 21111545 |
prevalence of toxoplasma gondii and neospora caninum antibodies in spanish ibex (capra pyrenaica hispanica). | a cross-sectional study was carried out on spanish ibex populations in southern spain to assess the seroprevalence of toxoplasma gondii and neospora caninum and to investigate the risk factors associated with these infections. using the modified agglutination test, the seroprevalence to t. gondii was 27.5% (146/531; ci(95%), 23.7-31.3), and this seropositivity significantly increased with age. among adults, statistically significant differences were observed between geographical locations and ov ... | 2010 | 21159529 |
use of acepromazine for stress control in spanish ibex (capra pyrenaica) captured by drive-net. | capture and restraint can induce stress in wild animals and tranquilizers may be beneficial in preventing some of the more adverse effects. a short-acting neuroleptic agent (acepromazine) was assessed in 25 spanish ibexes (capra pyrenaica) captured by drive-net. the animals were divided into a control group (14 ibexes) and a treated group (11 ibexes). heart rate and rectal temperature, as well as haematological and biochemical parameters, were used to evaluate the effects of tranquilization duri ... | 2010 | 19071042 |
evidence of peste des petits ruminants virus (pprv) infection in sindh ibex (capra aegagrus blythi) in pakistan as confirmed by detection of antigen and antibody. | an outbreak resulting in mortality in sindh ibex (capra aegagrus blythi) was investigated. there was a history of about 36 deaths (both young and adult) during the period of 1 month. disease appeared in a generalized form, affecting the respiratory and digestive systems. major lesions were respiratory distress, pustules on and in the mouth, ocular-nasal discharges, and severe diarrhea. the most significant lesion was the oculonasal discharges and diarrhea. deaths were mainly due to blindness, an ... | 2011 | 21221782 |
genetic variants of anaplasma phagocytophilum in wild caprine and cervid ungulates from the alps in tyrol, austria. | the occurrence of genetic variants of anaplasma phagocytophilum was studied in wild ungulates from the northern and central eastern alps in tyrol, austria. for this purpose, spleen samples collected from 53 game animals during the hunting season 2008/2009 (16 roe deer [capreolus capreolus], 10 red deer [cervus elaphus], 16 alpine chamois [rupicapra r. rupicapra], 7 alpine ibex [capra i. ibex], and 4 european mouflons [ovis orientalis musimon]) were analyzed. thirty-five animals originated from t ... | 2011 | 21323423 |
epizootiologic investigations of selected abortive agents in free-ranging alpine ibex (capra ibex ibex) in switzerland. | in the early 2000s, several colonies of alpine ibex (capra ibex ibex) in switzerland ceased growing or began to decrease. reproductive problems due to infections with abortive agents might have negatively affected recruitment. we assessed the presence of selected agents of abortion in alpine ibex by serologic, molecular, and culture techniques and evaluated whether infection with these agents might have affected population densities. blood and fecal samples were collected from 651 ibex in 14 col ... | 2011 | 21719818 |
effect of post-mortem time on post-thaw characteristics of spanish ibex (capra pyrenaica) spermatozoa. | viable epididymal sperm can be obtained in the spanish ibex during 24h after death, but it has been observed a significant effect of the post-mortem time on fertility success, so only goats inseminated with semen recovery during the first 8h became pregnant. the aim of this study was to determine the effect of post-mortem time on epididymal semen samples from of spanish ibex. for this purpose, sperm samples from 36 males were collected at different post-mortem times, from 2 to 24h, and cryoprese ... | 2011 | 22014412 |
ibex-associated malignant catarrhal fever-like disease in a group of bongo antelope (tragelaphus eurycerus). | a private zoological facility experienced an outbreak of malignant catarrhal fever (mcf) in 3 bongo antelope (tragelaphus eurycerus). all cases were periparturient bongos that presented acutely anorectic beginning ∼6 weeks after being housed with a nubian ibex. disease quickly progressed to respiratory distress and death within 24-72 hours of onset of clinical signs. consistent gross findings in affected bongos were pulmonary edema and small pale tan foci in the livers. histological lesions incl ... | 2011 | 22194357 |
effects of anesthetic protocols on electroejaculation variables of iberian ibex (capra pyrenaica). | the effects of three intramuscular anesthesia protocols--detomidine 190 μg/kg plus ketamine 2 mg/kg, detomidine 270 μg/kg plus ketamine 1.4 mg/kg, and tiletamine 3.4 mg/kg plus zolazepam 3.4 mg/kg--on penis protrusion and ejaculation variables were compared in nine captive spanish ibex (capra pyrenaica) subjected to electroejaculation. body temperature, heart, and respiratory rates, as well as a number of plasma biochemical variables were also recorded prior to and during anesthesia. the detomid ... | 2011 | 20542308 |
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 ... | 2011 | 21855981 |
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 ... | 2012 | 23029321 |
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 ... | 2012 | 22960215 |
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 ... | 2012 | 22740543 |
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 ... | 2012 | 22645301 |
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 ... | 2012 | 22582011 |
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 ... | 2012 | 22231373 |
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 ... | 2012 | 22119388 |
seroprevalence and risk factors associated to mycobacterium bovis in wild artiodactyl species from southern spain, 2006-2010. | the control of bovine tuberculosis (btb) is at a critical point in the last stage of eradication in livestock. wildlife species recently have emerged infected with tb in europe, particularly ungulates in the iberian peninsula. epidemiological information regarding tb in wild ungulates including affected species, prevalence, associated risk factors and appropriate diagnostic methods need to be obtained in these countries. a cross-sectional study was carried out on wild artiodactyl species, includ ... | 2012 | 22523563 |
applicability of major histocompatibility complex drb1 alleles as markers to detect vertebrate hybridization: a case study from iberian ibex × domestic goat in southern spain. | hybridization between closely related wild and domestic species is of great concern because it can alter the evolutionary integrity of the affected populations. the high allelic variability of major histocompatibility complex (mhc) loci usually excludes them from being used in studies to detect hybridization events. however, if a) the parental species don't share alleles, and b) one of the parental species possesses an exceptionally low number of alleles (to facilitate analysis), then even mhc l ... | 2012 | 23006678 |
protection of spanish ibex (capra pyrenaica) against bluetongue virus serotypes 1 and 8 in a subclinical experimental infection. | many wild ruminants such as spanish ibex (capra pyrenaica) are susceptible to bluetongue virus (btv) infection, which causes disease mainly in domestic sheep and cattle. outbreaks involving either btv serotypes 1 (btv-1) and 8 (btv-8) are currently challenging europe. inclusion of wildlife vaccination among btv control measures should be considered in certain species. in the present study, four out of fifteen seronegative spanish ibexes were immunized with a single dose of inactivated vaccine ag ... | 2012 | 22666321 |
prey preference of snow leopard (panthera uncia) in south gobi, mongolia. | accurate information about the diet of large carnivores that are elusive and inhabit inaccessible terrain, is required to properly design conservation strategies. predation on livestock and retaliatory killing of predators have become serious issues throughout the range of the snow leopard. several feeding ecology studies of snow leopards have been conducted using classical approaches. these techniques have inherent limitations in their ability to properly identify both snow leopard feces and pr ... | 2012 | 22393381 |
