[genetic polymorphism of the amylases found in species of artiodactyla by means of polyacrylamide gel electrophoresis].three different types of isoenzymes, am1, am2 and am3 have been revealed by polyacrylamide gel electrophoresis (pag) and affine pag electrophoresis in artiodactyla. in cattle and pigs am2 isoenzyme is monomorphic, as shown by pag electrophoresis, and polymorphic in affine gel separation (two alloenzymes, am2a and am2b have been revealed). some of sheep have no am2 isoenzyme, which, apparently, account for the presence of minus-allele. am2 isoenzyme was not detected in saiga tatarica which are re ...19836189765
detection and control of rotavirus infections in zoo animals.fecal specimens from 15 exotic animal species, with and without diarrhea, were examined for the presence of rotavirus, bacterial enteropathogens, and intestinal parasites. a commercial enzyme-linked immunosorbent assay was used to detect antigens of rotavirus. rotavirus was detected in the feces of 20 (57%) of 35 of the animals, which included addax (addax nasomaculatus), nyala (tragelaphus angasi), saiga (saiga tatarica), white-tailed gnu (connochaetus gnou), greater kudu (tragelaphus strepsice ...19836315660
warble flies (hypodermatidae, oestridae) of some wild animals from mongolia and tuva.three species of warble flies pallasiomyia antilopum, oestromyia leporina and cephalopina titilator from four species of wild animals were found. hitherto unknown larva of the first instar of pallasiomyia antilopum (pallas, 1771) collected from the saiga (saiga tatarica l.) is described.19817227873
ancient specimens and dna contamination: a case study from the 12s rrna gene sequence of the "linh duong" bovid (pseudonovibos spiralis).in 1993, several unusual horn sheaths, collected in the south of vietnam, were regarded as evidence for a new mammal species, pseudonovibos spiralis. however, the taxonomic status of p. spiralis remains a highly controversial subject: firstly, it has been related to three different groups of the family bovidae: antilopini (gazelles), bovini (oxen, bisons, and buffaloes), and caprini sensu lato (goats, sheep and allies). secondly, certain horns have been shown to be faked. most recently, it has b ...200212046628

toxoplasmosis in nilgais (boselaphus tragocamelus) and a saiga antelope (saiga tatarica).three captive female nilgais (boselaphus tragocamelus) either showed late-term abortion or their newborn calves died within 2 days of birth. toxoplasma gondii dna was demonstrated in the brain and liver of each fetus and in one of the two neonates by single-stage polymerase chain reaction (pcr) with tgr1e and by seminested pcr with b1 gene. retrospectively, antibodies titers > or =640 to t. gondii by indirect fluorescence were found in the sera of all three female and one male nilgais. no other ...200415732596
helminths of saiga antelope in kazakhstan: implications for conservation and livestock production.saiga antelope (saiga tatarica) graze extensively on livestock pasture, potentially enabling transmission of a wide range of parasitic helminths between saigas and domestic ruminants. thirty-six of the 38 species of helminth that have been found in saigas in kazakhstan in the past have been found also in domestic livestock. we examined 133 saigas culled for meat in autumn 1997, and found three species of cestode and 12 nematodes (nine in the abomasum), but no trematodes or lungworms. the most ab ...200515827221
the 'big spenders' of the steppe: sex-specific maternal allocation and twinning in the saiga polygynous mammals, males generally benefit more from extra allocation of maternal resources than females. however, limitations to sex-specific allocation are usually ignored. we propose the 'allocation constraint' hypothesis, whereby maternal resource allocation is more likely to follow life-history predictions in single sex litters than in mixed sex litters, due to limitations in prenatal resource targeting. consequently, for polygynous species, males in mixed litters are likely to receive ...200717341456
human influence on distribution and extinctions of the late pleistocene eurasian megafauna.late pleistocene extinctions are of interest to paleontological and anthropological research. in north america and australia, human occupation occurred during a short period of time and overexploitation may have led to the extinction of mammalian megafauna. in northern eurasia megafaunal extinctions are believed to have occurred over a relatively longer period of time, perhaps as a result of changing environmental conditions, but the picture is much less clear. to consider megafaunal extinction ...200818199470
data on phylogenetic analyses of gazelles (genus gazella) based on mitochondrial and nuclear intron markers.the data provided is related to the article "phylogenetic analyses of gazelles reveal repeated transitions of key ecological traits and provide novel insights into the origin of the genus gazella" [1]. the data is based on 48 tissue samples of all nine extant species of the genus gazella, namely gazella gazella, gazella arabica, gazella bennettii, gazella cuvieri, gazella dorcas, gazella leptoceros, gazella marica, gazella spekei, and gazella subgutturosa and four related taxa (saiga tatarica, a ...201627054158
identification of ungulates used in a traditional chinese medicine with dna barcoding technology.horns of saiga antelope (saiga tatarica) have always been an ingredient of "lingyangjiao", a traditional chinese medicine (tcm). persistent hunting for saiga antelope has already threatened the survival of critical endangered populations in wild. to control the growing pressure, cites and chinese government have legislated for monitoring the trade of saiga horns. however, similar ungulate horns are difficult to identify by their morphological characteristics, which has impeded the law enforcemen ...201526140198
the arterial circle of the brain, its branches and connections in selected representatives of the antilopinae.the arterial circle of the brain, that is, the circle of willis, and its branches in ruminants have been chiefly described in farm animals and only in selected wild species. in view of the deficit of information about this vascular region in numerous other species of the ruminantia, the arteries of the encephalic base were analyzed in five antelope species representing different genera of the bovidae, antilopinae. specimens of the following species were examined: springbuck (antidorcas marsupial ...201525694115
globalization of the cashmere market and the decline of large mammals in central drivers of terrestrial ecosystems, humans have replaced large carnivores in most areas, and human influence not only exerts striking ecological pressures on biodiversity at local scales but also has indirect effects in distant corners of the world. we suggest that the multibillion dollar cashmere industry creates economic motivations that link western fashion preferences for cashmere to land use in central asia. this penchant for stylish clothing, in turn, encourages herders to increase lives ...201323866036
deep sequencing of plant and animal dna contained within traditional chinese medicines reveals legality issues and health safety concerns.traditional chinese medicine (tcm) has been practiced for thousands of years, but only within the last few decades has its use become more widespread outside of asia. concerns continue to be raised about the efficacy, legality, and safety of many popular complementary alternative medicines, including tcms. ingredients of some tcms are known to include derivatives of endangered, trade-restricted species of plants and animals, and therefore contravene the convention on international trade in endan ...201222511890
seroprevalence of infectious diseases in saiga antelope (saiga tatarica tatarica) in kazakhstan 2012-2014.286 serum samples were collected from three sub-populations of saiga in kazakhstan (betpakdala, ustyurt and volga-ural) between 2012 and 2014, and were tested for the presence of antibodies to brucella spp., bluetongue virus, peste des petits ruminants (ppr) virus, akabane virus, schmallenberg virus, chlamydophila, toxoplasma, mycobacterium avium subspecies paratuberculosis and coxiella burnetii (q fever). seropositives to coxiella burnetii of saiga were detected and the adjusted seroprevalence ...201627094147
missing saiga on the taiga.conservation biologists understand that linking demographic histories of species at risk with causal biotic and abiotic events should help us predict the effects of ongoing biotic and abiotic change. in parallel, researchers have started to use ancient genetic information (adna) to explore the demographic histories of a number of species present in the pleistocene fossil record (see, e.g. shapiro et al. 2004). however, adna studies have primarily focused on identifying long-term population trend ...201021050292
