| the first detection of the tick-borne encephalitis virus (tbev) rna in dermacentor reticulatus ticks collected from the lowland european bison (bison bonasus bonasus l.). | tick borne encephalitis virus (tbev) (flaviviridae, flavivirus) is the causative agent of tick-borne encephalitis (tbe), a potentially fatal neurological infection. the disease is endemic in a large region in eurasia, where is transmitted mainly by hard ticks: ixodes ricinus and i. persulcatus. it is known that also dermacentor reticulatus is involved in a circulation of tbev, but the knowledge of its importance in the tbe epidemiology is still insufficient. the białowieża primeval forest is loc ... | 2016 | 26751883 |
| relationships between antimicrobial resistance, distribution of virulence factor genes and the origin of trueperella pyogenes isolated from domestic animals and european bison (bison bonasus). | trueperella pyogenes is an opportunistic pathogen causing suppurative infections in livestock and wild animals. although this bacterium is known for a long time, our knowledge about its pathogenicity is still insufficient. in this study the relationships between antimicrobial resistance profiles, distribution of virulence factor genes and the origin of t. pyogenes isolates were investigated. isolates (n = 97) from various infections in domestic animals and european bison were studied. minimal in ... | 2016 | 27154538 |
| trypanosoma vivax in water buffalo of the venezuelan llanos: an unusual outbreak of wasting disease in an endemic area of typically asymptomatic infections. | trypanosoma vivax has been associated with asymptomatic infections in african and south american buffalo. in this study, t. vivax was analyzed in water buffalo (bubalus bubalis) from venezuela in a molecular survey involving 293 blood samples collected from 2006 to 2015 across the llanos region. results demonstrated constant infections (average 23%) during the years analyzed. in general, animals were healthy carriers of t. vivax with low levels of parasitemia and were diagnosed exclusively by tv ... | 2016 | 27884441 |
| histophilosis as a natural disease. | histophilus somni is responsible for sporadic disease worldwide in cattle and, to a lesser extent, in small ruminants, bighorn sheep (ovis canadensis), and north american bison (bison bison). the importance of h. somni diseases can be attributed to improved clinical and laboratory recognition, combined with the growth in intensive management practices for cattle. although outbreaks of bovine histophilosis can occur year-round, in northern and southern hemispheres, it is most frequent in late fal ... | 2016 | 26847357 |
| risk factors for mycoplasma bovis-associated disease in farmed bison (bison bison) herds in western canada: a case-control study. | north american bison producers have been attempting to control and prevent mycoplasma bovis-associated disease without the benefit of bison-specific knowledge. the objective of this study was to determine the clinical presentation of disease associated with m. bovis infection in western canadian farmed bison, and to identify herd-level risk factors for m. bovis-associated disease. bison producers (n=49) from western canada (manitoba, saskatchewan, alberta, and british columbia) were selected for ... | 2016 | 27317324 |
| mycoplasma bovis isolates recovered from cattle and bison (bison bison) show differential in vitro effects on pbmc proliferation, alveolar macrophage apoptosis and invasion of epithelial and immune cells. | in the last few years, several outbreaks of pneumonia, systemically disseminated infection, and high mortality associated with mycoplasma bovis (m. bovis) in north american bison (bison bison) have been reported in alberta, manitoba, saskatchewan, nebraska, new mexico, montana, north dakota, and kansas. m. bovis causes chronic pneumonia and polyarthritis syndrome (cpps) in young, stressed calves in intensively-managed feedlots. m. bovis is not classified as a primary pathogen in cattle, but in b ... | 2016 | 27016754 |
| in vitro antimicrobial susceptibility of mycoplasma bovis clinical isolates recovered from bison (bison bison). | mycoplasma bovis is a pathogen globally affecting cattle and bison herds, causing pneumonia, arthritis, mastitis, abortions, and other symptoms, leading to huge economic losses. many studies have been done regarding the antimicrobial susceptibility of m. bovis isolated from cattle, but no such study is available for isolates recovered from bison. for the first time, in vitro susceptibilities of 40 m. bovis clinical isolates collected from bison herds in canada are reported here. minimal inhibito ... | 2016 | 26854525 |
| estimating neospora caninum prevalence in wildlife populations using bayesian inference. | prevalence of disease in wildlife populations, which is necessary for developing disease models and conducting epidemiologic analyses, is often understudied. laboratory tests used to screen for diseases in wildlife populations often are validated only for domestic animals. consequently, the use of these tests for wildlife populations may lead to inaccurate estimates of disease prevalence. we demonstrate the use of bayesian latent class analysis (lca) in determining the specificity and sensitivit ... | 2016 | 27099713 |
| risk assessment and management of brucellosis in the southern greater yellowstone area (ii): cost-benefit analysis of reducing elk brucellosis prevalence. | recent cases of bovine brucellosis (brucella abortus) in cattle (bos taurus) and domestic bison (bison bison) of the southern greater yellowstone area (sgya) have been traced back to free-ranging elk (cervus elaphus). several management activities have been implemented to reduce brucellosis seroprevalence in elk, including test-and-slaughter, low-density feeding at elk winter feedgrounds, and elk vaccination. it is unclear which of these activities are most cost-effective at reducing the risk of ... | 2016 | 27836044 |
| anti-brucella antibodies in moose (alces alces gigas), muskoxen (ovibos moschatus), and plains bison (bison bison bison) in alaska, usa. | we used an indirect enzyme-linked immunosorbent assay (ielisa) and the rose bengal test (rbt) to test for anti-brucella antibodies in moose (alces alces gigas), muskoxen (ovibos moschatus), and plains bison (bison bison bison) from various game management units (gmus) in alaska, us, sampled from 1982 to 2010. a portion of the sera had previously been tested with the standard plate test (spt), the buffered brucella antigen (bba) card test, and the card test (card). no antibody-positive plains bis ... | 2016 | 26540335 |
| serological study of exposure to selected arthropod-borne pathogens in european bison (bison bonasus) in poland. | bison bonasus is an indigenous species of central and eastern europe with the largest wild population inhabiting białowieża primeval forest; however, free-living and captive european bison are reared in many countries around the world. despite that the european bison was rescued from the extinction after the first world war, it remains as endangered species. changing environment as well as human activity may have contributed to the observed increase of the risk of the emergence and re-emergence ... | 2016 | 27291825 |
| mitochondrial genome analysis reveals historical lineages in yellowstone bison. | yellowstone national park is home to one of the only plains bison populations that have continuously existed on their present landscape since prehistoric times without evidence of domestic cattle introgression. previous studies characterized the relatively high levels of nuclear genetic diversity in these bison, but little is known about their mitochondrial haplotype diversity. this study assessed mitochondrial genomes from 25 randomly selected yellowstone bison and found 10 different mitochondr ... | 2016 | 27880780 |
| novel graphical analyses of runs of homozygosity among species and livestock breeds. | runs of homozygosity (roh), uninterrupted stretches of homozygous genotypes resulting from parents transmitting identical haplotypes to their offspring, have emerged as informative genome-wide estimates of autozygosity (inbreeding). we used genomic profiles based on 698 k single nucleotide polymorphisms (snps) from nine breeds of domestic cattle (bos taurus) and the european bison (bison bonasus) to investigate how roh distributions can be compared within and among species. we focused on two len ... | 2016 | 27872841 |
| early cave art and ancient dna record the origin of european bison. | the two living species of bison (european and american) are among the few terrestrial megafauna to have survived the late pleistocene extinctions. despite the extensive bovid fossil record in eurasia, the evolutionary history of the european bison (or wisent, bison bonasus) before the holocene (<11.7 thousand years ago (kya)) remains a mystery. we use complete ancient mitochondrial genomes and genome-wide nuclear dna surveys to reveal that the wisent is the product of hybridization between the e ... | 2016 | 27754477 |
| lack of effects of ooplasm transfer on early development of interspecies somatic cell nuclear transfer bison embryos. | successful development of iscnt (interspecies somatic cell nuclear transfer) embryos depends on complex interactions between ooplasmic and nuclear components, which can be compromised by genetic divergence. transfer of ooplasm matching the genetic background of the somatic cell in iscnt embryos is a valuable tool to study the degree of incompatibilities between nuclear and ooplasmic components. this study investigated the effects of ooplasm transfer (ot) on cattle (bos taurus) and plains bison ( ... | 2016 | 27737629 |
| lessons for livestock genomics from genome and transcriptome sequencing in cattle and other mammals. | decreasing sequencing costs and development of new protocols for characterizing global methylation, gene expression patterns and regulatory regions have stimulated the generation of large livestock datasets. here, we discuss experiences in the analysis of whole-genome and transcriptome sequence data. | 2016 | 27534529 |
| foraging decisions underlying restricted space use: effects of fire and forage maturation on large herbivore nutrient uptake. | recent models suggest that herbivores optimize nutrient intake by selecting patches of low to intermediate vegetation biomass. we assessed the application of this hypothesis to plains bison (bison bison) in an experimental grassland managed with fire by estimating daily rates of nutrient intake in relation to grass biomass and by measuring patch selection in experimental watersheds in which grass biomass was manipulated by prescribed burning. digestible crude protein content of grass declined li ... | 2016 | 27547359 |
| influence of management and biological factors on the parasitic invasions in the wild-spread of blood-sucking nematode ashworthius sidemi in european bison (bison bonasus). | the full course of new parasite introductions in wild animals is difficult to accurately trace. we documented and analysed the invasive blood-sucking nematode ashworthius sidemi (trichostrongylidae) introduction and spread in european bison (bison bonasus) from the initial phase of its progression. in the polish part of the białowieża primeval forest (bpf) the parasite was first found in 2000. from 2002 to 2015, 165 culled bison were investigated. the prevalence and intensity of a. sidemi schulz ... | 2016 | 27761404 |
| resorptive depressions on a horn core of late pleistocene (mis 3) bison priscus (bovidae, mammalia) from northeastern germany. | this report describes an isolated right horn core of a fossil steppe bison (bison priscus) recovered from late pleistocene deposits near langsdorf in the federal state of mecklenburg-vorpommern (germany). ams radiocarbon dating provided an age of 45353±2894cal yr bp for the specimen. the horn core, which by morphological criteria belonged to a female, has two depressions in its basal portion that differ in size, shape, and depth. while depressions are known from horn cores of domestic cattle, sh ... | 2016 | 29539557 |
| elk resource selection and implications for anthrax management in montana. | anthrax, caused by the spore-forming bacterium bacillus anthracis, is a zoonotic disease that affects humans and animals throughout the world. in north america, anthrax outbreaks occur in livestock and wildlife species. vaccine administration in wildlife is untenable; the most effective form of management is surveillance and decontamination of carcasses. successful management is critical because untreated carcasses can create infectious zones increasing risk for other susceptible hosts. we studi ... | 2016 | 29887642 |
| space use and movement patterns in a semi-free-ranging herd of european bison (bison bonasus). | the successful reintroduction and restocking of the european bison demands a reliable knowledge of the biology of this species. yet little is known to date about the european bison, and empirical data remains insufficient to set up a reliable plan ensuring the reintroduction, maintenance and survival of populations in habitats that have been largely modified by human activity. studies of the ecology, social behaviour and management of bison are therefore crucial to the conservation of this speci ... | 2016 | 26841107 |
| developmental competence of 8?16-cell stage bison embryos produced by interspecies somatic cell nuclear transfer. | altered communication between nuclear and cytoplasmic components has been linked to impaired development in interspecies somatic cell nuclear transfer (iscnt) embryos as a result of genetic divergence between the two species. this study investigated the developmental potential and mitochondrial function of cattle (bos taurus), plains bison (bison bison bison) and wood bison (bison bison athabascae) embryos produced by iscnt using domestic cattle oocytes as cytoplasts. embryos in all groups were ... | 2015 | 25763855 |
| genome-wide association study for posthitis in the free-living population of european bison (bison bonasus). | about 5-6% of the european bison (bison bonasus) males are affected by posthitis (necrotic inflammation of the prepuce) and die in the wild forest. despite many years of study, pathogenesis of this disease has not yet been determined. the main aim of the study was to find snp markers significantly associated with the incidence of posthitis and mine the genome for candidate genes potentially involved in the development of the disease. | 2015 | 25585689 |
| the occurrence of anaplasma phagocyto- philum in wild bison from the bialowieza primeval forest in eastern poland. | the aim of the present study was to investigate the occurrence of anaplasma spp. in a group of 120 wild bison (bison bonasus) from the bialowieza primeval forest in eastern poland and to determine which species of anaplasma could infect these animals based on a pcr of a part of the 16s rrna gene followed by sequencing. the pcr technique showed the presence of 16s rrna anaplasma spp. genetic material in the blood of 22 from a total of 120 animals. dna amplification by means of the primers ehr 521 ... | 2015 | 26281444 |
| [mycobacterium infection in prehistoric humans: co-evolution in remote ages]. | the introduction of agriculture and animal husbandry at the end of the mesolithic era, despite enabling a significant demographic growth through an increase in food storage and availability, caused new infectious noxae to enter the pathocoenosis. however in the palaeolithic era, hunter-gatherers were already in contact with infectious diseases of animal origin, albeit episodically. modern biomedical technologies allow us to estimate, with better approximation, how long mankind has been in contac ... | 2015 | 25819058 |
| cross-reactivity of neutralizing antibodies among malignant catarrhal fever viruses. | some members of the gamma herpesvirus genus macavirus are maintained in nature as subclinical infections in well-adapted ungulate hosts. transmission of these viruses to poorly adapted hosts, such as american bison and cattle, can result in the frequently fatal disease malignant catarrhal fever (mcf). based on phylogenetic analysis, the mcf viruses (mcfv) cluster into two subgroups corresponding to the reservoir hosts' subfamilies: alcelaphinae/hippotraginae and caprinae. antibody cross-reactivi ... | 2015 | 26658281 |
| the infection of reintroduced ruminants - bison bonasus and alces alces - with anaplasma phagocytophilum in northern poland. | the north-eastern part of poland is considered an area of high risk for infection with tick-borne diseases, including with human granulocytic ehrlichiosis (hge) agents. the etiological agent of hge is anaplasma phagocytophilum. as the animal reservoir for a. phagocytophilum in the environment serve the species from cervidae and bovidae families. european bison (bison bonasus) and elk (alces alces) are the big ruminant species, reintroduced to the forests of middle europe after many decades of ab ... | 2015 | 26408585 |
| sequence analysis of bitter taste receptor gene repertoires in different ruminant species. | bitter taste has been extensively studied in mammalian species and is associated with sensitivity to toxins and with food choices that avoid dangerous substances in the diet. at the molecular level, bitter compounds are sensed by bitter taste receptor proteins (t2r) present at the surface of taste receptor cells in the gustatory papillae. our work aims at exploring the phylogenetic relationships of t2r gene sequences within different ruminant species. to accomplish this goal, we gathered a colle ... | 2015 | 26061084 |
| seasonal shifts in diet and gut microbiota of the american bison (bison bison). | north american bison (bison bison) are becoming increasingly important to both grassland management and commercial ranching. however, a lack of quantitative data on their diet constrains conservation efforts and the ability to predict bison effects on grasslands. in particular, we know little about the seasonality of the bison diet, the degree to which bison supplement their diet with eudicots, and how changes in diet influence gut microbial communities, all of which play important roles in ungu ... | 2015 | 26562019 |
| black-tailed prairie dogs, cattle, and the conservation of north america's arid grasslands. | prairie dogs (cynomys spp.) have been eliminated from over 95% of their historic range in large part from direct eradication campaigns to reduce their purported competition with cattle for forage. despite the longstanding importance of this issue to grassland management and conservation, the ecological interactions between cattle and prairie dogs have not been well examined. we address this issue through two complementary experiments to determine if cattle and prairie dogs form a mutualistic gra ... | 2015 | 25760377 |
| hunting the extinct steppe bison (bison priscus) mitochondrial genome in the trois-frères paleolithic painted cave. | despite the abundance of fossil remains for the extinct steppe bison (bison priscus), an animal that was painted and engraved in numerous european paleolithic caves, a complete mitochondrial genome sequence has never been obtained for this species. in the present study we collected bone samples from a sector of the trois-frères paleolithic cave (ariège, france) that formerly functioned as a pitfall and was sealed before the end of the pleistocene. screening the dna content of the samples collect ... | 2015 | 26083419 |
| observations on sporulation of eimeria bovis (apicomplexa: eimeriidae) from the european bison bison bonasus: effect of temperature and potassium dichromate solution. | the present study was designed to determine the influence of temperature and the addition of potassium dichromate solution (k2cr2o7) on the efficiency of sporulation of eimeria bovis (zublin, 1908), a coccidian species most commonly diagnosed in european bison bison bonasus (linnaeus). sporulation under conventional conditions (2.5% dichromate solution, 23 °c) was completed on the fourth day of incubation (control), whereas the oocyst development took two days more at the temperature of 18 °c, a ... | 2015 | 25960564 |
| development of a multiplex pcr for identification of dictyocaulus lungworms in domestic and wild ruminants. | dictyocaulus lungworms are the causative agents of parasitic bronchitis (dictyocaulosis) characterised by coughing and severe lung pathology in domestic and wild ruminants. the objective of this study was to design a simple molecular test that could detect of lungworm dna from both adult and larval lungworms and could distinguish between the most common dictyocaulus species found in cattle and in some species of wild ruminants. a multiplex pcr test with four novel primers targeting species-speci ... | 2015 | 26266883 |
| malignant catarrhal fever: an emerging disease in the african buffalo (syncerus caffer). | within the tribe bovini in the subfamily bovinae, the water buffalo (bubalus bubalis), american bison (bison bison), european bison (bubalus bonasus) and yak (bos grunniens) are recognized as species highly susceptible to malignant catarrhal fever (mcf). in contrast, the lack of reports describing clinical mcf in the african buffalo (syncerus caffer) whether free ranging or captive has led to a perception that african buffaloes are resistant to mcf. during the last decade, several cases of mcf i ... | 2015 | 23957274 |
| a serological and molecular study on the occurrence of mycoplasmas in european bison (bison bonasus) from two areas of eastern poland. | european bison (bison bonasus) from two different areas of eastern poland showing gross pathology possibly associated with mycoplasma infections were tested for ruminant mycoplasma species using serological and molecular methods. fifty-five samples, blood or tissue were collected from 28 animals during 2013-2014. six sera were positive for mycoplasma bovis. the elisa and complement fixation test for mycoplasma mycoides subsp. mycoides gave a few weak reactions, but were negative by immunoblottin ... | 2015 | 26812834 |
| bayesian analysis to evaluate tests for the detection of mycobacterium bovis infection in free-ranging wild bison (bison bison athabascae) in the absence of a gold standard. | we estimated the sensitivity and specificity of the caudal-fold skin test (cft), the fluorescent polarization assay (fpa), and the rapid lateral-flow test (rt) for the detection of mycobacterium bovis in free-ranging wild wood bison (bison bison athabascae), in the absence of a gold standard, by using bayesian analysis, and then used those estimates to forecast the performance of a pairwise combination of tests in parallel. in 1998-99, 212 wood bison from wood buffalo national park (canada) were ... | 2015 | 25973619 |
| hepatitis e virus antibody prevalence in wildlife in poland. | hepatitis e is an important public health problem mostly in developing but occasionally also in industrialized countries. domestic and wildlife animals are considered reservoirs of the hepatitis e virus (hev). since no information on the prevalence of autochthonous hev infections in human and animal in poland is available, the aim of the study was to investigate the hev seroprevalence of different wildlife species as potential virus reservoirs in the country. no hev antibodies were found in any ... | 2015 | 24655475 |
| european bison as a refugee species? evidence from isotopic data on early holocene bison and other large herbivores in northern europe. | according to the refugee species concept, increasing replacement of open steppe by forest cover after the last glacial period and human pressure had together forced european bison (bison bonasus)--the largest extant terrestrial mammal of europe--into forests as a refuge habitat. the consequent decreased fitness and population density led to the gradual extinction of the species. understanding the pre-refugee ecology of the species may help its conservation management and ensure its long time sur ... | 2015 | 25671634 |
| effect of reproductive seasonality on gamete quality in the north american bison (bison bison bison). | the objective was to investigate the effects of reproductive seasonality on gamete quality in plains bison (bison bison bison). epididymal sperm (n = 61 per season), collected during the breeding season (july-september), had significantly higher post-thaw total motility (36.76 ± 14.18 vs 31.24 ± 12.74%), and lower linearity (0.36 ± 0.06 vs 0.39 ± 0.04) and wobbliness (0.49 ± 0.04 vs 0.51 ± 0.03; mean ± sd) compared to non-breeding season (january-march) samples. representative samples (n = 4) fr ... | 2015 | 25529116 |
| persistent müllerian duct syndrome (pmds) in the polish free-ranged bull populations of the european bison (bison bonasus l.). | this study describes the diversity of vestigial male uteri of the european bison (eb) examined for: (1) morphology, (2) glycoprotein localization, (3) total protein and glycoprotein profiles, (4) steroid concentrations, and (5) pmds based on the mutation of amh and amhr2 genes. uteri of adult bulls (5-12 years old) were compared to a uterus of a juvenile female (6 months old). male uterine proteins were analyzed in parallel to secretory endometrial proteins of pseudo-pregnant pig (psend) and bsa ... | 2015 | 25498147 |
| sarcocystis cruzi infection in wood bison (bison bison athabascae). | endangered wood bison (bison bison athabascae) is the largest terrestrial mammal in the american continent. animal health is an important issue in their conservation, and sarcocystis cruzi may be a cause of clinical disease in bovidae. hearts of eight wood bison from alaska, usa were examined for sarcocysts by histology, transmission electron microscopy, pepsin digestion, and molecularly. sarcocystis bradyzoites were found in pepsin digests of all eight and sarcocysts were found in histologic se ... | 2015 | 25868849 |
| first steps into the wild - exploration behavior of european bison after the first reintroduction in western europe. | biodiversity is rapidly declining globally. one strategy to help to conserve species is to breed species in captivity and release them into suitable habitats. the way that reintroduced animals explore new habitats and/or disperse from the release site is rarely studied in detail and represents key information for the success of reintroduction projects. the european bison (bison bonasus l. 1758) was the largest surviving herbivore of the post-glacial megafauna in europe before it became extinct i ... | 2015 | 26605549 |
| genetic analysis of the henry mountains bison herd. | wild american plains bison (bison bison) populations virtually disappeared in the late 1800s, with some remnant animals retained in what would become yellowstone national park and on private ranches. some of these private bison were intentionally crossbred with cattle for commercial purposes. this forced hybridization resulted in both mitochondrial and nuclear introgression of cattle genes into some of the extant bison genome. as the private populations grew, excess animals, along with their his ... | 2015 | 26673758 |
| coronary arteries of the european bison (bison bonasus). | the european bison (bison bonasus) is an endangered species. more information on its anatomy is needed as only few studies have been published. this study is the first report on the morphology of the coronary vessels. given the anatomical similarity between the european bison and other ruminants, the results of this study can be applied to other species, including endangered ones. | 2015 | 26608615 |
| climatic warming and the future of bison as grazers. | climatic warming is likely to exacerbate nutritional stress and reduce weight gain in large mammalian herbivores by reducing plant nutritional quality. yet accurate predictions of the effects of climatic warming on herbivores are limited by a poor understanding of how herbivore diet varies along climate gradients. we utilized dna metabarcoding to reconstruct seasonal variation in the diet of north american bison (bison bison) in two grasslands that differ in mean annual temperature by 6 °c. here ... | 2015 | 26567987 |
| inducing ovulation in wood bison (bison bison athabascae) during the anovulatory season. | as part of the development of a germplasm biobank to preserve the genetic diversity of threatened wood bison (bison bison athabascae), a 2 × 2 factorial study was designed to determine the effects of ovulation induction agent and follicle maturity on the ovulatory response in wood bison during the anovulatory season. bison (n=32) were assigned randomly to four groups (n=8/group) and treated with either plh or hcg when a growing dominant follicle was either 8-9 mm or ≥10 mm. the ovaries were exam ... | 2015 | 26490189 |
| bilateral pneumothoraces following biv icd placement: a case of buffalo chest syndrome. | contralateral pneumothorax following device implantation on the left side has been reported in a few cases. the majority of contralateral pneumothoraces showed evidence of atrial perforation on computed tomography (ct), echocardiography, or chest x-rays and required lead revision. to the best of our knowledge there is only 1 other reported case of contralateral pneumothorax without evidence of macro-displacement of the atrial lead. in that case the patient experienced a right-sided pneumothorax ... | 2015 | 26431396 |
| bison distribution under conflicting foraging strategies: site fidelity vs. energy maximization. | foraging strategies based on site fidelity and maximization of energy intake rate are two adaptive forces shaping animal behavior. whereas these strategies can both be evolutionarily stable, they predict conflicting optimal behaviors when population abundance is in decline. in such a case, foragers employing an energy-maximizing strategy should reduce their use of low-quality patches as interference competition becomes less intense for high-quality patches. foragers using a site fidelity strateg ... | 2015 | 26378302 |
| recovering aspen follow changing elk dynamics in yellowstone: evidence of a trophic cascade? | to investigate the extent and causes of recent quaking aspen (populus tremuloides) recruitment in northern yellowstone national park, we measured browsing intensity and height of young aspen in 87 randomly selected aspen stands in 2012, and compared our results to similar data collected in 1997-1998. we also examined the relationship between aspen recovery and the distribution of rocky mountain elk (cervus elaphus) and bison (bison bison) on the yellowstone northern ungulate winter range, using ... | 2015 | 26236910 |

| to follow or not? how animals in fusion-fission societies handle conflicting information during group decision-making. | when group members possess differing information about the environment, they may disagree on the best movement decision. such conflicts result in group break-ups, and are therefore a fundamental driver of fusion-fission group dynamics. yet, a paucity of empirical work hampers our understanding of how adaptive evolution has shaped plasticity in collective behaviours that promote and maintain fusion-fission dynamics. using movement data from gps-collared bison, we found that individuals constantly ... | 2015 | 26013202 |
| tuberculosis and brucellosis in wood bison (bison bison athabascae) in northern canada: a renewed need to develop options for future management. | effective, long-term strategies to manage the threat of bovine tuberculosis and brucellosis spillback from northern, diseased bison to the canadian cattle herd and adjacent disease-free wood bison (bison bison athabascae) herds have eluded policy makers in recent decades. a controversial plan to depopulate infected herds and repopulate them with disease-free wood bison was rejected in 1990 because of significant public concern. since then, technical advances in vaccine technology, genetic salvag ... | 2015 | 25973624 |
| competition on the range: science vs. perception in a bison-cattle conflict in the western usa. | 1. competition between livestock and wild ungulates is commonly perceived to occur on shared rangelands. in the henry mountains (hm) of utah, a free-ranging population of bison bison bison has raised concerns among ranchers holding grazing permits on these public lands. bison are the most conspicuous potential competitors with cattle, but lagomorphs (mainly jackrabbits lepus californicus) are also abundant in this area. the local ranching community is applying political pressure on state and fed ... | 2015 | 25960573 |
| equivalence between step selection functions and biased correlated random walks for statistical inference on animal movement. | animal movement has a fundamental impact on population and community structure and dynamics. biased correlated random walks (bcrw) and step selection functions (ssf) are commonly used to study movements. because no studies have contrasted the parameters and the statistical properties of their estimators for models constructed under these two lagrangian approaches, it remains unclear whether or not they allow for similar inference. first, we used the weak law of large numbers to demonstrate that ... | 2015 | 25898019 |

| pharmacokinetics of tulathromycin after subcutaneous injection in north american bison (bison bison). | tulathromycin is approved for the treatment of respiratory disease in cattle and swine. it is intended for long-acting, single-dose injection therapy (draxxin), making it particularly desirable for use in bison due to the difficulty in handling and ease of creating stress in these animals. the pharmacokinetic properties of tulathromycin in bison were investigated. ten wood bison received a single 2.5 mg/kg subcutaneous injection of draxxin. serum concentrations were measured by liquid chromatogr ... | 2015 | 25772094 |
| influence of group size on the success of wolves hunting bison. | an intriguing aspect of social foraging behaviour is that large groups are often no better at capturing prey than are small groups, a pattern that has been attributed to diminished cooperation (i.e., free riding) in large groups. although this suggests the formation of large groups is unrelated to prey capture, little is known about cooperation in large groups that hunt hard-to-catch prey. here, we used direct observations of yellowstone wolves (canis lupus) hunting their most formidable prey, b ... | 2014 | 25389760 |
| bison grazing increases arthropod abundance and diversity in a tallgrass prairie. | how grazing-induced ecosystem changes by ungulates indirectly affect other consumers is a question of great interest. i investigated the effect of grazing by american bison (bos bison l.) on an arthropod community in tallgrass prairie. grazing increased the abundance of arthropods, an increase that was present in both herbivorous and carnivorous assemblages, but not in detritivores. the increase in herbivores and reduction in plant biomass from grazing resulted in an arthropod herbivore load alm ... | 2014 | 25198902 |
