the european bison (bison bonasus) as an indicatory species for the circulation of tick-borne encephalitis virus (tbev) in natural foci in poland.tick-borne encephalitis (tbe) is one of the most common zoonotic diseases in europe transmitted by ixodidae vectors. while small mammals such as bank voles and ticks constitute the main reservoirs for virus transmission, large sylvatic species act as a food source for ticks. cervids such as roe deer and red deer are considered sentinel species for tbe in natural foci. in addition, an increase of the population size and density of large wild mammals in an area corresponds to an increase in the ti ...202134358779
detection of tick-borne pathogens in red deer (cervus elaphus), united kingdom.deer represent a major vertebrate host for all feeding stages of the hard tick ixodes ricinus in the united kingdom (uk), and could play a role in the persistence of tick-borne pathogens. however, there have been few studies reporting the presence of babesia spp. and anaplasma phagocytophilum in deer in the uk, and those that detected babesia were unable to confirm the species. to address this, we have investigated blood samples from red deer (cervus elaphus) for the presence of tick-borne patho ...202134070977
a survey of shared pathogens at the domestic-wild ruminants' interface in doñana national park (spain).a cross-sectional study was carried out to evaluate shared pathogens that can be transmitted by close or non-close contact at the domestic-wild ruminants' interface. during summer-autumn 2015, a total of 138 cattle and 203 wild ruminants (red deer, cervus elaphus, and fallow deer, dama dama) were sampled in doñana national park (dnp, south-western spain), a mediterranean ecosystem well known for the interaction network occurring in the ungulate host community. pestiviruses, bovine respiratory sy ...202133900033
schmallenberg virus, cyclical reemergence in the core region: a seroepidemiologic study in wild cervids, belgium, 2012-2017.schmallenberg virus emerged in 2011 in europe. the epicentre of primordial spreading was the region straddling germany, the netherlands and belgium. one of the key questions is whether the newcomer would establish a lasting presence on the continent. the apparent seroprevalence in southern belgium wild deer populations was followed for 6 years. two years of intense circulation were revealed, 2012 and 2016, characterized by a peak seroprevalence in the two studied populations (capreolus capreolus ...202133949132
long-term determinants of the seroprevalence of the bluetongue virus in deer species in southern spain.bluetongue is a vector-borne disease affecting domestic and wild ruminants, with a major socioeconomic impact. endemic circulation of the bluetongue virus serotype 4 (btv-4) and btv-1 have occurred in spain since 2004 and 2007, respectively. however, epidemiological studies have seldom been approached from a long-term perspective in wild ruminants. a total of 881 deer (red deer and fallow deer) were necropsied from 2005 to 2018 as part of the dnp health-monitoring program. serum samples were tes ...202134280654
mammalian orthoreovirus (mrv) is widespread in wild ungulates of northern italy.mammalian orthoreoviruses (mrvs) are emerging infectious agents that may affect wild animals. mrvs are usually associated with asymptomatic or mild respiratory and enteric infections. however, severe clinical manifestations have been occasionally reported in human and animal hosts. an insight into their circulation is essential to minimize the risk of diffusion to farmed animals and possibly to humans. the aim of this study was to investigate the presence of likely zoonotic mrvs in wild ungulate ...202133546342
shedding of mycobacterium caprae by wild red deer (cervus elaphus) in the bavarian alpine regions, germany.the number of natural infections with mycobacterium caprae in wildlife and in cattle in the bavarian and austrian alpine regions has increased over the last decade. red deer (cervus elaphus) have been recognized as maintenance reservoir; however, the transmission routes of m. caprae among and from naturally infected red deer are unknown. the unexpected high prevalence in some hot spot regions might suggest an effective indirect transmission of infection. therefore, this study was undertaken to d ...202031512795
valuing biodiversity attributes: a choice experiment design.this study seeks to estimate household's willingness to pay for biodiversity conservation in dachigam national park, which houses the last viable population of asiatic black bear and the hangul (which is the only surviving sub-species of red deer in the world). a survey based on choice experiment method was carried out at dachigam national park, an area that is threatened by several anthropogenic pressures. a set of attributes, such as endangered species, national park area and research and educ ...202032648162
endozoochorous dispersal by herbivores and omnivores is mediated by germination conditions.vertebrate-mediated seed dispersal is probably the main long distance dispersal mode. through endozoochory, large mammals act as mobile links between habitats within and among forest patches. along with other factors, their feeding regimes do affect their contribution as dispersal vectors. we conducted a cross-species comparative experiment involving two herbivores, red deer and roe deer; and two opportunistic omnivores, wild boar and brown bear, all occurring in the forest and steppe-forest eco ...202032867734

identifying maintenance hosts for infection with dichelobacter nodosus in free-ranging wild ruminants in switzerland: a prevalence study.footrot is a worldwide economically important, painful, contagious bacterial foot disease of domestic and wild ungulates caused by dichelobacter nodosus. benign and virulent strains have been identified in sheep presenting with mild and severe lesions, respectively. however, in alpine ibex (capra ibex ibex), both strains have been associated with severe lesions. because the disease is widespread throughout sheep flocks in switzerland, a nationwide footrot control program for sheep focusing on vi ...202031917824
temporal and spatial spread of hypoderma actaeon infection in roe deer from peninsular spain determined by an indirect enzyme-linked immunosorbent assay.the host switching of hypoderma actaeon (diptera: oestridae), a specific parasite of red deer (cervus elaphus), towards roe deer (capreolus capreolus) has been recently reported in spain. to provide information about the temporal and spatial spreading of h. actaeon infection in roe deer, 244 serum samples from animals hunted in spain between 2013 and 2018 were analysed by an indirect enzyme-linked immunosorbent assay. the overall seropositivity was 13.9%. seropositivity was higher in continental ...202031444796
characterisation of faecal staphylococci from roe deer (capreolus capreolus) and red deer (cervus elaphus) and their susceptibility to gallidermin.our current knowledge of microbiota in wild ruminants is limited. the goal of this study was to evaluate staphylococcal species in red and roe deer for various attributes (haemolysis, dnase, and urease activities; lactic acid and biofilm production; and antibiotic profile) and their susceptibility to gallidermin. sixteen staphylococcal strains were identified from faeces of 21 free-living animals (9 adult female cervus elaphus-red deer and 12 young female capreolus capreolus-roe deer) sampled by ...202030710249
pressure algometry validation and determination of efficacy of articaine hydrochloride ring block in antler removal in red deer (cervus elaphus).new zealand deer farming centres on the production of meat and velvet antler. velvet antler removal is a painful procedure and currently, new zealand animal welfare regulations dictate surgical removal of velvet antlers under lignocaine anaesthesia. to improve our knowledge on the efficacy and duration of other local anaesthetics to mitigate pain after antler removal, it is important to accurately assess and quantify pain arising from antler removal. therefore, the current study was designed to ...202033153106
the dark ventral patch: a bimodal flexible trait related to male competition in red deer.sexual signals play a central role in male-male competition in polygynous species. in red deer (cervus elaphus), male's ventral area become dark during the rutting season due to urine spraying behaviour and retains many chemical compounds potentially revealing individual features. here we investigate the variation in size of this trait, exploring its relationship with age and male competitive features such as antlers or body size, as well as populational level of intrasexual competition for mate ...202033151970
the importance of individual movement and feeding behaviour for long-distance seed dispersal by red deer: a data-driven model.long-distance seed dispersal (ldd) has strong impacts on the spatiotemporal dynamics of plants. large animals are important ldd vectors because they regularly transport seeds of many plant species over long distances. while there is now ample evidence that behaviour varies considerably between individual animals, it is not clear to what extent inter-individual variation in behaviour alters seed dispersal by animals.202033133610
bilateral antler sequestration above the coronet in a red deer (cervus elaphus) stag-insights into the process of antler casting.this paper reports a case of delayed velvet shedding and bilateral premature antler casting above the coronets in a young adult red deer stag from germany. based on the established role of testosterone in the control of the antler cycle, the antler abnormality is considered to have been the result of a (temporary) androgen deficiency. the basal surfaces (separation planes or seals) of the cast antlers were markedly concave. scanning electron microscopy revealed that the separation plane was dens ...202033128478
plantain (plantago lanceolata) reduces the environmental impact of farmed red deer (cervus elaphus).the objective of this study was to evaluate the effect of plantain (plantago lanceolata l.) on water dynamics and balance, as well as nitrogen (n) excretion by red deer (cervus elaphus l.) as a potential forage tool to reduce negative environmental impacts. this experiment used a crossover design with red deer (n = 8) in metabolism crates to determine how fresh-cut herbage diets of either plantain or ryegrass (lolium perenne l.) compared in terms of dry matter intake (dmi), diet digestibility, w ...202033123680
transstadial transmission from nymph to adult of coxiella burnetii by naturally infected hyalomma lusitanicum.coxiella burnetii (derrick) philip, the causative agent of q fever, is mainly transmitted by aerosols, but ticks can also be a source of infection. transstadial and transovarial transmission of c. burnetii by hyalomma lusitanicum (koch) has been suggested. there is a close relationship between this tick species, wild animals and c. burnetii but the transmission in a natural environment has not been demonstrated. in this study, we collected 80 engorged nymphs of h. lusitanicum from red deer and w ...202033113791
temporal trends (1953-2012) of toxic and essential elements in red deer antlers from northeastern deer antlers have a number of advantages that make them a unique material for monitoring trace elements. as antlers are shed and regrown every year, results of toxicological investigations can be applied to a particular region and time. we analyzed the content of four toxic (pb, cd, hg, as) and three essential (cu, zn, fe) trace elements in 254 red deer antler samples spanning between 1953 and 2012. age of stags did not influence concentrations of analyzed elements in antlers, except for zn ...202033113660
interspecific interactions among functionally diverse frugivores and their outcomes for plant reproduction: a new approach based on camera-trap data and tailored null models.the study of plant-frugivore interactions is essential to understand the ecology and evolution of many plant communities. however, very little is known about how interactions among frugivores indirectly affect plant reproductive success. in this study, we examined direct interactions among vertebrate frugivores sharing the same fruit resources. then, we inferred how the revealed direct interspecific interactions could lead to indirect (positive or negative) effects on reproductive success of fle ...202033064761
elk population dynamics when carrying capacities vary within and among herds.population and land management relies on understanding population regulation and growth, which may be impacted by variation in population growth parameters within and among populations. we explored the interactions between variation in carrying capacity (k), intrinsic population growth rate (r), and strength of density dependence (β) within and among elk (cervus elaphus) herds in a small part of the geographic range of the species. we also estimated stochastic fluctuations in abundance around k ...202032994437
impact of freeze-thaw cycles on die-off of e. coli and intestinal enterococci in deer and dairy faeces: implications for landscape contamination of watercourses.characterising faecal indicator organism (fio) survival in the environment is important for informing land management and minimising public health risk to downstream water users. however, key gaps in knowledge include understanding how wildlife contribute to catchment-wide fio sources and how fio survival is affected by low environmental temperatures. the aim of this study was to quantify e. coli and intestinal enterococci die-off in dairy cow versus red deer faecal sources exposed to repeated f ...202032987924
comparative metabolomics study revealed difference in central carbon metabolism between sika deer and red deer antler.the antler regeneration has been well studied for the past two decades and adopted in the regenerative medicine model for studying on developmental biology. despite our growing knowledge of functional molecules regulating antler regeneration, we still do not know whether antler from different deer species possess the exact same mechanism or not. our previous comparative study between sika deer and red deer suggests that the metabolic pathways between them are profoundly different based on protei ...202032908856
