| isolation of pregnancy-associated glycoproteins from placenta of the american bison (bison bison) at first half of pregnancy. | this paper describes the successful purification and characterisation of pregnancy-associated glycoproteins (pag) extracted from placenta (3-4 months) of american bisons (amb). chorionic ambpag proteins were purified from foetal cotyledonary tissues (ct) and liquid cotyledonary-carrying proteins (lcp) leaking from damaged cells. our protocols successfully indicated the usefulness of ambpag protein identification, especially from lcp fraction. the ambpags were extracted, precipitated and eluted d ... | 2008 | 17543308 |
| pyric herbivory: rewilding landscapes through the recoupling of fire and grazing. | our understanding of fire and grazing is largely based on small-scale experimental studies in which treatments are uniformly applied to experimental units that are considered homogenous. any discussion of an interaction between fire and grazing is usually based on a statistical approach that ignores the spatial and temporal interactions on complex landscapes. we propose a new focus on the ecological interaction of fire and grazing in which each disturbance is spatially and temporally dependent o ... | 2008 | 19183203 |
| malignant catarrhal fever in a captive american bison (bison bison) in italy. | malignant catarrhal fever (mcf) is a fatal, systemic disease of cattle and other domestic and wild ruminants that, in europe, is caused by ovine herpesvirus 2 (ovhv-2). american bison (bison bison) are highly susceptible to the disease. an adult american bison, housed in a zoo in southern italy in close cohabitation with a group of domestic sheep (ovis aries aries) displayed clinical signs that resembled the acute form of mcf. by real-time polymerase chain reaction, ovhv-2 dna was detected intra ... | 2008 | 18987244 |
| patterns of genetic variation in us federal bison herds. | like many wide-ranging mammals, american bison (bison bison) have experienced significant range contraction over the past two centuries and are maintained in artificially isolated populations. a basic understanding of the distribution of genetic variation among populations is necessary to facilitate long-term germplasm preservation and species conservation. the 11 herds maintained within the us federal system are a critically important source of germplasm for bison conservation, as they include ... | 2008 | 19017265 |
| shapes of differential pulse voltammograms and level of metallothionein at different animal species. | metallothioneins play a key role in maintaining homeostasis of essential metalsand in protecting of cells against metal toxicity as well as oxidative damaging. exceptinghumans, blood levels of metallothionein have not yet been reported from any animalspecies. blood plasma samples of 9 animal species were analysed by the adsorptive transferstripping technique to obtain species specific voltammograms. quite distinct records wereobtained from the takin (budorcas taxicolor), while other interesting ... | 2007 | 28903235 |
| detection of mitochondrial dna from domestic cattle in bison on santa catalina island. | in 1924, 14 american bison (bison bison) were introduced to santa catalina island, california and sporadically supplemented thereafter with additional animals. to reduce the herd and its impact on native vegetation, over 2000 animals have been exported during the past four decades. today, the herd is estimated to contain around 250 individuals. genetic analysis was performed on 98 animals removed from the island in 2004. forty-four samples (45%) had domestic cattle mitochondrial dna (mtdna), 12 ... | 2007 | 17573784 |
| carnivore repatriation and holarctic prey: narrowing the deficit in ecological effectiveness. | the continuing global decline of large carnivores has catalyzed great interest in reintroduction to restore populations and to reestablish ecologically functional relationships. i used variation in the distribution of four holarctic prey species and their behavior as proxies to investigate the pace and intensity by which responses are lost or reinvigorated by carnivore repatriation. by simulating the presence of wolves (canis lupus), tigers (panthera tigris), and brown bears (ursus arctos) at 19 ... | 2007 | 17650259 |
| covariates affecting spatial variability in bison travel behavior in yellowstone national park. | understanding mechanisms influencing the movement paths of animals is essential for comprehending behavior and accurately predicting use of travel corridors. in yellowstone national park (usa), the effects of roads and winter road grooming on bison (bison bison) travel routes and spatial dynamics have been debated for more than a decade. however, no rigorous studies have been conducted on bison spatial movement patterns. we collected 121 380 locations from 14 female bison with gps collars in cen ... | 2007 | 17708218 |

| preliminary assessment of reproductive technologies in wood bison (bison bison athabascae): implications for preserving genetic diversity. | since the high prevalence of bovine tuberculosis and brucellosis in free-ranging wood bison in the canadian north poses a threat to nearby healthy bison populations, commercial bison and cattle ranches, and potentially to humans, there is considerable impetus to salvage the genetics of infected bison and maintain a disease-free herd. in that regard, there is a great need to develop appropriate reproductive technologies. therefore, the objective of this study was to develop protocols to produce a ... | 2007 | 17498795 |
| mhc-drb3 variation in a free-living population of the european bison, bison bonasus. | mhc genes play a crucial role in pathogen recognition and are the most polymorphic genes in vertebrates. loss of variation in these genes in bottlenecked species is thought to put their survival at risk. we examined variation at the mhc ii drb3 locus in the european bison, bison bonasus, a species that has undergone an extreme bottleneck: the current population originated from only 12 founders. we also tested for the association of drb3 genes with the incidence of posthitis, a disease affecting ... | 2007 | 17257111 |
| complete genomes and phylogenetic positions of bovine papillomavirus type 8 and a variant type from a european bison. | the dna of bovine papillomavirus (bpv) type 8 was extracted from papillomas on cattle kept in japan, and dna of bovine papillomavirus bpv-8-eb was extracted from a european bison (bison bonasus) born in italy and released into the wild in slovakia. the dna genomes of these bpvs were amplified using multiply primed rolling circle amplification and polymerase chain reaction, then characterized by direct sequencing method. the bpv-8 and bpv-8-eb genomes consisted of 7,791 base pairs (bp) and 7,773 ... | 2007 | 17265141 |
| resistance to malignant catarrhal fever in american bison (bison bison) is associated with mhc class iia polymorphisms. | the rhadinovirus ovine herpesvirus-2 (ovhv-2) is the most common causative agent of malignant catarrhal fever (mcf) in clinically susceptible ruminants including cattle and bison. american bison (bison bison) are highly susceptible to clinical mcf. nevertheless, approximately 20% of bison on ranches or in feedlots become infected with the virus without developing clinical disease. defining the genetic basis for differences in susceptibility between bison could facilitate development of improved ... | 2007 | 17326800 |
| intra-nasal inoculation of american bison (bison bison) with ovine herpesvirus-2 (ovhv-2) reliably reproduces malignant catarrhal fever. | sheep-associated malignant catarrhal fever (mcf) due to infection with ovine herpesvirus 2 (ovhv-2) is common in commercial herds of american bison ( bison bison). inability to propagate ovhv-2 in vitro has been a constraint on experimental studies of the disease. we sought to establish whether nasal secretions from sheep that shed ovhv-2 might induce the disease in bison and to define a minimum challenge dose. fourteen bison were nebulized with sheep nasal sections containing 10(3)-10(7) ovhv-2 ... | 2007 | 17846237 |
| mycobacterium avium subspecies paratuberculosis in bison (bison bison) from northern canada. | nested polymerase chain reaction (pcr) using the mycobacterium avium subspecies paratuberculosis (map)-specific region, locus 251, was used as a screening tool for the detection of map dna in fecal samples from northern canadian bison herds. further characterization of positive samples (26/835) was performed because map dna was found without signs of disease. strain typing, using pcr-restriction endonucleas assay (rea), was limited to two samples but revealed that the samples corresponded to a c ... | 2007 | 17984279 |
| prevalence of escherichia coli o157:h7 in the american bison (bison bison). | bison is becoming a popular meat source for consumers, but very little is known about the bison's status with respect to escherichia coli o157:h7. we conducted a study to determine the prevalence and identify virulence genes and pulsed-field genetic types of e. coli o157:h7 in bison. rectal contents and rectoanal mucosal swab (rams) samples were collected from a total of 342 bison at slaughter on seven different dates. isolation of e. coli o157:h7 was by enrichment, immunomagnetic separation, an ... | 2007 | 18044434 |
| historic distribution and challenges to bison recovery in the northern chihuahuan desert. | ecologists and conservationists have long assumed that large grazers, including bison (bison bison), did not occur in post-pleistocene southwestern north america. this perception has been influential in framing the debate over conservation and land use in the northern chihuahuan desert. the lack of an evolutionary history of large grazers is being used to challenge the validity of ranching as a conservation strategy and to limit the protection and reintroduction of bison as a significant compone ... | 2007 | 18173472 |
