| genetic epidemiology of sarcoptes scabiei in the iberian wolf in asturias, spain. | during the last decades, attempts have been made to understand the molecular epidemiology of sarcoptes scabiei, and to detect and clarify the differences between isolates from different hosts and geographic regions. two main phenomena have been described: (i) host-taxon derived-sarcoptes mite infection in european wild animals (revealing the presence of three separate clusters, namely herbivore-, carnivore- and omnivore-derived sarcoptes populations in europe) and (ii) prey-to-predator sarcoptes ... | 2013 | 23664709 |
| 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 ... | 2017 | 28453544 |
| endemic occurrence of fasciola hepatica in an alpine ecosystem, pyrenees, northeastern spain. | fasciola hepatica is a liver parasite of ruminants whose distribution is determined by its intermediate host, the freshwater snail galba truncatula. in europe, f. hepatica is mostly associated with lowlands. infection from sympatric domestic reservoirs is rarely reported in wild mountain ungulates. this study explores f. hepatica in a multi-host system in a european alpine area. serum samples (n = 1,209) from pyrenean chamois (rupicapra p. pyrenaica), european mouflon (ovis aries musimon), domes ... | 2020 | 33012085 |
| self-clearance of pestivirus in a pyrenean chamois (rupicapra pyrenaica) population. | understanding the dynamics of host-pathogen interaction is key to the management of epidemics. a pestivirus belonging to the border disease virus group 4 emerged around 2001 in pyrenean chamois (rupicapra pyrenaica) in spain and france. the virus had significant demographic impact in some populations, but it was less harmful and more endemic in other places. the determinants of these local variations are still unclear. here, we documented empirical evidence of self-clearance of the virus in a ch ... | 2017 | 29148885 |
| long-term dynamics of mycoplasma conjunctivae at the wildlife-livestock interface in the pyrenees. | functional roles of domestic and wild host populations in infectious keratoconjunctivitis (ikc) epidemiology have been extensively discussed claiming a domestic reservoir for the more susceptible wild hosts, however, based on limited data. with the aim to better assess ikc epidemiology in complex host-pathogen alpine systems, the long-term infectious dynamics and molecular epidemiology of mycoplasma conjunctivae was investigated in all host populations from six study areas in the pyrenees and on ... | 2017 | 29016676 |
| tall grass invasion after grassland abandonment influences the availability of palatable plants for wild herbivores: insight into the conservation of the apennine chamois rupicapra pyrenaica ornata. | invasion of the tall grass brachypodium genuense was observed in an area of the central apennines (italy) where the population size of apennine chamois (rupicapra pyrenaica ornata) was in strong decline. since this dominant tall grass threatens biodiversity and forage quality, our hypothesis was that b. genuense abundance influenced that of palatable species for the chamois, depending on their functional traits and distribution patterns. our sampling design used plots of 10 × 10 m and 1 × 1 m to ... | 2016 | 26899738 |
| 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 ... | 2016 | 27769278 |
| detection of rickettsia helvetica in ixodes ricinus ticks collected from pyrenean chamois in france. | seventy-one ixodes ricinus ticks collected from pyrenean chamois (rupicapra pyrenaica) in the french pyrenees were tested by real-time polymerase chain reaction to detect the presence of rickettsia and bartonella. four ticks (6%) were positive for r. helvetica. the chamois carries infected ticks, and this enables the dissemination throughout the environment with this bacterium, a potential human pathogen. | 2012 | 23141107 |
| infectious keratoconjunctivitis in wild caprinae: merging field observations and molecular analyses sheds light on factors shaping outbreak dynamics. | infectious keratoconjunctivitis (ikc) is an ocular infectious disease caused by mycoplasma conjunctivae which affects small domestic and wild mountain ruminants. domestic sheep maintain the pathogen but the detection of healthy carriers in wildlife has raised the question as to whether m. conjunctivae may also persist in the wild. furthermore, the factors shaping the dynamics of ikc outbreaks in wildlife have remained largely unknown. the aims of this study were (1) to verify the etiological rol ... | 2017 | 28259139 |
| giardia duodenalis in alpine (rupicapra rupicapra rupicapra) and apennine (rupicapra pyrenaica ornata) chamois. | although chamois rupicapra spp. are the most abundant mountain ungulates in europe, no data are available on the presence of giardia duodenalis infecting these species. | 2015 | 26691178 |
| bluetongue virus serotype 1 in wild ruminants, france, 2008-10. | the persistence of bluetongue virus serotype 1 (btv-1) circulation was evaluated in red deer (cervus elaphus), roe deer (capreolus capreolus), mouflons (ovis ammon), and pyrenean chamois (rupicapra pyrenaica pyrenaica) sampled during two hunting seasons between september 2008 and february 2010 in the east pyrenean mountains, france. the prevalence of btv antibody in red deer was high and not significantly different between the two hunting seasons (50.9% and 49.6%, respectively). the prevalence o ... | 2012 | 23060507 |
| experimental infection with chamois border disease virus causes long-lasting viraemia and disease in pyrenean chamois (rupicapra pyrenaica). | since 2001, severe outbreaks of disease associated with border disease virus (bdv) infection have been reported in the pyrenean chamois. the disease is characterized by variable degrees of cachexia, alopecia and neurological manifestations prior to death. the aim of this study was to investigate this disease under experimental conditions. to assess viral virulence, humoral immune response, dissemination and probable routes of transmission, seven chamois (five seronegative and two seropositive to ... | 2011 | 21775580 |
| border disease virus shedding and detection in naturally infected pyrenean chamois (rupicapra pyrenaica). | pyrenean chamois (rupicapra pyrenaica) populations of the central and eastern pyrenees have been affected by severe outbreaks associated with border disease virus (bdv) since 2001. eight pyrenean chamois (7 males and 1 female) from 1 to 8 years of age with clinical signs consistent with bdv infection were studied. at necropsy, whole blood, tissue samples (skin, brain, prescapular lymph node, thyroid gland, lung, liver, spleen, kidney, small intestine, bone marrow, and testicle), urine, and nasal ... | 2010 | 20807933 |
| haematology and serum chemistry of pyrenean chamois (rupicapra pyrenaica) naturally infected with a border disease virus. | in 2005 and 2006 an outbreak of disease associated with border disease virus (bdv) infection caused high mortality in the pyrenean chamois (rupicapra pyrenaica) in the catalan pyrenees (ne spain). the aim of this study was to determine values for different haematological and serum biochemical analytes in 32 free-ranging pyrenean chamois affected by the disease and to compare them with those obtained from healthy chamois. in the affected chamois red blood cell counts, haemoglobin concentrations, ... | 2011 | 20656309 |
| experimental infection of pigs with border disease virus isolated from pyrenean chamois (rupicapra pyrenaica). | between 2001 and 2007, several outbreaks of disease associated with border disease virus (bdv) infection were reported in the central pyrenees (northeast spain) and were associated with a major reduction in chamois (rupicapra pyrenaica) populations. at the same time, wild boars (sus scrofa) from the same area were found to be seropositive to this pestivirus, without showing clinical signs. the present study examines the susceptibility of domestic swine and the course of the infection with a bdv ... | 2010 | 20453208 |
| diversity and evolution of the mhc-drb1 gene in the two endemic iberian subspecies of pyrenean chamois, rupicapra pyrenaica. | major histocompatibility complex class ii locus drb variation was investigated by single-strand conformation polymorphism analysis and sequence analysis in the two subspecies of pyrenean chamois (rupicapra pyrenaica) endemic to the iberian peninsula. low levels of genetic variation were detected in both subspecies, with seven different alleles in r. p. pyrenaica and only three in the r. p. parva. after applying the rarefaction method to cope with the differences in sample size, the low allele nu ... | 2007 | 17551521 |
| cerebral coeneurosis in chamois (rupicapra pyrenaica). | two cases of cerebral coeneurosis in chamois (rupicapra pyrenaica) from catalonia (northeastern spain) are described. this disease, of which few cases have been reported, may, in fact, be relatively frequent. although the characteristic symptom of the disease in sheep is circling, that symptom was not observed in this study. chamois may act as a host within the sheep-shepherd-dog cycle, but is probable that red fox (vulpes vulpes) also acts as a definitive host. | 1995 | 8546018 |
| prevalence of toxoplasma gondii antibodies in red deer (cervus elaphus) and other wild ruminants from spain. | serum samples from 441 red deer (cervus elaphus) and 161 other wild ruminant species, collected between 1993 and 2005 from six regions of spain were tested for antibodies against toxoplasma gondii by the modified agglutination test (mat). antibodies to t. gondii (mat 1:25 or higher) were detected in 15.6% of red deer. statistically significant differences were observed among sampling sites with seroprevalence in red deer from catalonia (42.2%) being significantly higher compared with other spani ... | 2006 | 16359801 |
| effect of perphenazine enanthate in pyrenean chamois (rupicapra pyrenaica). | perphenazine enanthate was used to allow adaptation to captivity in 11 pyrenean chamois (rupicapra pyrenaica). at the time of capture, all animals received 0.10 mg/kg of acepromazine maleate and 2.5 mg/kg of perphenazine enanthate intramuscularly. the effect was evaluated by means of three behaviors: alertness, defecation, and flight distance. the tranquilization and lack of fear of humans of all animals were determined and the usefulness of this long-acting tranquilizer for chamois adaptation t ... | 2013 | 24450074 |
| new insights on pestivirus infections in transhumant sheep and sympatric pyrenean chamois (rupicapra p. pyrenaica). | border disease virus (bdv) causes health and economic impact on livestock and is also of importance in wildlife conservation as it causes high mortality outbreaks in pyrenean chamois (rupicapra pyrenaica pyrenaica). pastoral practices are known as a main interspecies pathogen transmission. hence, the presence of pestivirus in transhumant sheep flocks and sympatric chamois was assessed in areas with different epidemiological scenarios of chamois bdv infections. moreover, the present study had als ... | 2018 | 29615262 |
| a novel epidemiological model to better understand and predict the observed seasonal spread of pestivirus in pyrenean chamois populations. | seasonal variations in individual contacts give rise to a complex interplay between host demography and pathogen transmission. this is particularly true for wild populations, which highly depend on their natural habitat. these seasonal cycles induce variations in pathogen transmission. the seasonality of these biological processes should therefore be considered to better represent and predict pathogen spread. in this study, we sought to better understand how the seasonality of both the demograph ... | 2015 | 26208716 |
| detection of porcine circovirus 3 in wildlife species in spain. | porcine circovirus 3 (pcv-3) is the third member of the family circoviridae, genus circovirus, able to infect swine. a high prevalence of viral dna has been recorded in wild boars. recently, pcv-3 dna was identified in italian wild ruminants. based on these previous results, this study assessed the frequency of pcv-3 dna detection in free-ranging ruminants and lagomorpha species in spain. in addition, the genetic characterization of the pcv-3 pcr-positive samples was performed. a total of 801 se ... | 2020 | 32369945 |
| distribution of pestivirus exposure in wild ruminants in spain. | a large-scale study was carried out to determine the prevalence of antibodies against pestivirus species in wild ruminants and describe their spatial variation in mainland spain. serum samples of 1,874 wild ruminants from different regions of this country were collected between the years 2000 and 2017. a total of 6.6% (123/1,874) animals showed antibodies against pestivirus by both blocking elisa (belisa) and virus neutralization tests (vnt). the prevalence of antibodies against pestiviruses was ... | 2020 | 32920992 |
| serosurveillance of schmallenberg virus in wild ruminants in spain. | schmallenberg disease (sbd) is an emerging vector-borne disease that affects domestic and wild ruminants. a long-term serosurvey was conducted to assess exposure to schmallenberg virus (sbv) in all the wild ruminant species present in mainland spain. between 2010 and 2016, sera from 1,216 animals were tested for antibodies against sbv using a commercial blocking elisa. the overall prevalence of antibodies was 27.1% (95%ci: 24.7-29.7). statistically significant differences among species were obse ... | 2020 | 32530115 |
| low sequence diversity of the prion protein gene (prnp) in wild deer and goat species from spain. | the first european cases of chronic wasting disease (cwd) in free-ranging reindeer and wild elk were confirmed in norway in 2016 highlighting the urgent need to understand transmissible spongiform encephalopathies (tses) in the context of european deer species and the many individual populations throughout the european continent. the genetics of the prion protein gene (prnp) are crucial in determining the relative susceptibility to tses. to establish prnp gene sequence diversity for free-ranging ... | 2018 | 29631620 |
| joint effects of weather and interspecific competition on foraging behavior and survival of a mountain herbivore. | weather variations have the potential to influence species interactions, although effects on competitive interactions between species are poorly known. both weather and competition can influence foraging behavior and survival of herbivores during nursing/weaning, a critical period in the herbivore life cycle. we evaluated the joint effects of weather and competition with red deer cervus elaphus on the foraging behavior of adult female apennine chamois rupicapra pyrenaica ornata in summer, and on ... | 2019 | 30936905 |
| mycoplasma conjunctivae in insect vectors and anatomic locations related to transmission and persistence. | mycoplasma conjunctivae is an obligate microparasite that causes infectious keratoconjunctivitis (ikc) in caprinae species. ikc is a long-recognised disease, but little attention has been paid to the mechanisms of transmission of the mycoplasma and its occurrence in locations other than the eyes. in this study, the presence of m. conjunctivae is assessed in the eyes, external ear canals (eec), nasal cavity, and vagina of host species as well as in potential vectors, which may be involved in the ... | 2019 | 30593383 |
| diversity of eimeria species in wild chamois rupicapra spp.: a statistical approach in morphological taxonomy. | wildlife is frequently infected by intestinal protozoa, which may threaten their fitness and health. a diverse community of eimeria species is known to occur in the digestive tract of mountain-dwelling ungulates, including chamois (genus rupicapra). however, available data on eimeria diversity in these taxa is at times inconsistent and mostly dated. in the present study, we aimed to revisit the occurrence of eimeria spp. in the alpine subspecies of the northern chamois (rupicapra rupicapra rupic ... | 2020 | 33173795 |
| a negative association between horn length and survival in a weakly dimorphic ungulate. | while all models of sexual selection assume that the development and expression of enlarged secondary sexual traits are costly, males with larger ornaments or weapons generally show greater survival or longevity. these studies have mostly been performed in species with high sexual size dimorphism, subject to intense sexual selection. here, we examined the relationships between horn growth and several survival metrics in the weakly dimorphic pyrenean chamois (rupicapra pyrenaica). in this unhunte ... | 2020 | 32211156 |
| sanitary emergencies at the wild/domestic caprines interface in europe. | population density and distribution of the four native european wild caprines (rupicapra rupicapra, rupicapra pyrenaica, capra ibex, capra pyrenaica) have increased in recent decades. the improved conservation status of this valuable wildlife, while a welcome event in general terms, is at the same time a matter of concern since, intuitively, frequent and tighter contacts with sympatric livestock imply a greater risk of cross-transmission of emerging and re-emerging pathogens, and offer unexpecte ... | 2019 | 31694211 |
| temporal variation in foraging activity and grouping patterns in a mountain-dwelling herbivore: environmental and endogenous drivers. | in temperate ecosystems, seasonality influences animal behaviour. food availability, weather, photoperiod and endogenous factors relevant to the biological cycle of individuals have been shown as major drivers of temporal changes in activity rhythms and group size/structure of herbivorous species. we evaluated how diurnal female foraging activity and grouping patterns of a mountain herbivore, the apennine chamois rupicapra pyrenaica ornata, varied during a decreasing gradient of pasture availabi ... | 2019 | 31330169 |
| comparing the accuracy of pcr-capillary electrophoresis and cuticle microhistological analysis for assessing diet composition in ungulates: a case study with pyrenean chamois. | the study of diet composition is required to understand the interactions between animal and plant ecosystems. different non-invasive techniques applied on faecal samples have commonly been used for such purposes, with cuticle microhistological analysis (cma) and emerging dna-based methods being the most relevant. in this work, we refined and optimized a qualitative dna-based approach combining pcr amplification of long trnl(uaa) and its2 fragments and capillary electrophoresis (pcr-ce), instead ... | 2019 | 31116750 |
| experimental infection with high- and low-virulence strains of border disease virus (bdv) in pyrenean chamois (rupicapra p. pyrenaica) sheds light on the epidemiological diversity of the disease. | since 2001, pyrenean chamois (rupicapra pyrenaica pyrenaica) populations have been affected by border disease virus (bdv) causing mortalities of more than 80% in some areas. field studies carried out in france, andorra, and spain have shown different epidemiological scenarios in chamois populations. this study was designed to confirm the presence of bdv strains of a high and low virulence in free-ranging chamois populations from pyrenees and to understand the implications of these findings to th ... | 2019 | 30963719 |
| detection of tick-borne pathogens in questing ixodes ricinus in the french pyrenees and first identification of rickettsia monacensis in france. | ticks are important vectors of several human and animal pathogens. in this study, we estimated the prevalence of important tick-borne infections in questing ticks from an area in southwestern france (hautes-pyrénées) inhabited by pyrenean chamois (rupicapra pyrenaica pyrenaica) experiencing high tick burden. we examined adult and nymph ticks collected by the flag dragging method from 8 to 15 sites in the pic de bazès during the years 2009, 2011, 2013 and 2015. pcr assays were conducted on select ... | 2019 | 30943150 |
| different effects of alpine woody plant expansion on domestic and wild ungulates. | changes in land-use and climate affect the distribution and diversity of plant and animal species at different spatiotemporal scales. the extent to which species-specific phenotypic plasticity and biotic interactions mediate organismal adaptation to changing environments, however, remains poorly understood. woody plant expansion is threatening the extent of alpine grasslands worldwide, and evaluating and predicting its effects on herbivores is of crucial importance. here, we explore the impact o ... | 2019 | 30737872 |
| seasonal diet composition of pyrenean chamois is mainly shaped by primary production waves. | in alpine habitats, the seasonally marked climatic conditions generate seasonal and spatial differences in forage availability for herbivores. vegetation availability and quality during the growing season are known to drive life history traits of mountain ungulates. however, little effort has been made to understand the association between plant phenology and changes in the foraging strategies of these mountain dwellers. furthermore, this link can be affected by the seasonal presence of livestoc ... | 2019 | 30673757 |
| demographic stochasticity drives epidemiological patterns in wildlife with implications for diseases and population management. | infectious diseases raise many concerns for wildlife and new insights must be gained to manage infected populations. wild ungulates provide opportunities to gain such insights as they host many pathogens. using modelling and data collected from an intensively monitored population of pyrenean chamois, we investigated the role of stochastic processes in governing epidemiological patterns of pestivirus spread in both protected and hunted populations. we showed that demographic stochasticity led to ... | 2018 | 30442961 |
| extender osmolality, glycerol and egg yolk on the cryopreservation of epididymal spermatozoa for gamete banking of the cantabric chamois (rupicapra pyrenaica parva). | germplasm banking is a key technology enabling the ex-situ conservation of wild species. however, cryopreservation protocols must be tested to assure the applicability of the banked material. the objective of this study was defining a range of parameters for the composition of a semen extender for cantabrian chamois epididymal spermatozoa (post-mortem collection). the freezing extender was based in a tes-tris-fructose buffer, modifying its composition in three experiments: osmolality of the buff ... | 2019 | 30408702 |
| effect of length of time post-mortem on quality and freezing capacity of cantabric chamois (rupicapra pyrenaica parva) epididymal spermatozoa. | genome resource banks are keystones in the ex-situ conservation of wild species. post-mortem (pm) collection of epididymal spermatozoa is an opportunistic and valuable source of germplasm, the time from the death of the animal limits its use. seeking to improve germplasm preservation strategies for the chamois (rupicapra sp.), the effect of pm time on epididymal sperm quality and freezability was studied using the cantabrian chamois. samples were classified according to pm collection time, up to ... | 2018 | 30301620 |
| from gestation to weaning: combining robust design and multi-event models unveils cost of lactation in a large herbivore. | the cost of current reproduction on survival or future reproduction is one of the most studied trade-offs governing resource distribution between fitness components. results have often been clouded, however, by the existence of individual heterogeneity, with high-quality individuals able to allocate energy to several functions simultaneously, at no apparent cost. surprisingly, it has also rarely been assessed within a breeding season by breaking down the various reproductive efforts of females f ... | 2017 | 28772345 |
| effects of season and postmortem changes on blood analytes in pyrenean chamois (rupicapra pyrenaica pyrenaica). | our objectives were to evaluate the effects of the 1) season, and 2) postmortem changes on serum biochemistries related with metabolism in pyrenean chamois (rupicapra pyrenaica pyrenaica). serum samples from 98 animals obtained from 2009 to 2012 were included. to investigate seasonal influences on blood parameters, the pyrenean chamois were captured in drive-nets during the feed abundant (fa; n=32) and food deficient (fd; n=35) seasons. to evaluate the possible differences in biochemistry analyt ... | 2017 | 28640711 |
| the physiological cost of male-biased parasitism in a nearly monomorphic mammal. | even though male-biased parasitism is common in mammals, little effort has been made to evaluate whether higher parasitic burden in males results in an extra biological cost, and thus a decrease in fitness. body condition impairment and the augmentation of oxidative stress can be used as indicators of the cost of parasite infections. here, we examined relationships between gastrointestinal and respiratory helminths, body condition and oxidative stress markers (glutathione peroxidase, paraoxonase ... | 2017 | 28431550 |

| onset of autumn shapes the timing of birth in pyrenean chamois more than onset of spring. | in seasonal environments, birth dates are a central component for a species' life history, with potential long-term fitness consequences. yet our understanding of selective pressures of environmental changes on birth dates is limited in wild mammals due to the difficulty of data collection. in a context of rapid climate change, the question of a possible mismatch between plant phenology and birth phenology also remains unanswered for most species. we assessed whether and how the timing of birth ... | 2016 | 26503480 |
| immobilizing the vulnerable apennine chamois (rupicapra pyrenaica ornata) with a low-dose xylazine-ketamine combination, reversed with idazoxan or atipamezole. | little information is available on chemical capture of the vulnerable subspecies within the genus rupicapra. low-dosage combinations of xylazine and ketamine were tested for immobilization of captive and free-ranging apennine chamois, rupicapra pyrenaica ornata (85 and 66 immobilizations, respectively) in a retrospective analysis. of the six dosage groups, all of them providing an acceptable level of immobilization, the optimal trade-off between safety and efficacy was found following administra ... | 2015 | 26056871 |
| male-biased gastrointestinal parasitism in a nearly monomorphic mountain ungulate. | pyrenean chamois (rupicapra pyrenaica pyrenaica) is a nearly monomorphic mountain ungulate with an unbiased sex-specific overwinter adult survival. few differences in gastrointestinal parasitism have been reported by coprology as yet. this study aims to assess diversity, prevalence, intensity of infection and aggregation of gastrointestinal nematodes in male and female adult chamois. we expect no differences in the parasite infection rates between sexes. | 2015 | 25888900 |
| the shared mitochondrial genome of rupicapra pyrenaica ornata and rupicapra rupicapra cartusiana: old remains of a common past. | mitochondrial dna (mtdna) has largely been used for species delimitation. however, mtdna introgression across species boundaries can lead to inconsistent phylogenies. partial sequences of the mitochondrial genome in the chamois, genus rupicapra, show the presence of three well differentiated clades, west (mtw), central (mtc) and east (mte), each with a geographically restricted distribution. the complete mtdnas of the clades mtw and mte (main representatives of the two currently considered speci ... | 2014 | 25047552 |
