european mink-polecat hybridization events: hazards from natural process?determining the significance of hybridization events raises essential issues both in conservation and in evolutionary biology. here, we report a genetic investigation of sympatric polecat and endangered european mink populations. although the two species were morphologically very similar, the european mink and the polecat were easily discriminated from allozymes and microsatellites and showed a high level of private alleles (effective number of alleles: mink=1.45 and polecat=3.09). nevertheless, ...200615653561
embryo development and embryo transfer in the european mink (mustela lutreola), an endangered mustelid species.the european mink is an endangered mustelidae species and thus requires effective conservation measures, although little is known about reproduction in this species. in particular, preimplantation development has not been studied and, therefore, embryonic development and the growth of embryos was documented in the present study for european mink using light and fluorescent microscopy. embryos develop in the oviducts and then migrate into the uterus on day 6 post coitum (p.c.) at the morula stage ...200616737639
conservation of the european mink (mustela lutreola): focus on reproduction and reproductive technologies.the european mink (mustela lutreola) is a small mammal, which belongs to the mustelidae family (carnivora). earlier, the range of distribution of this species encompassed much of the european continent. during the 20th century, the numbers of european mink declined and the range of its distribution became reduced to three fragmented populations; today this species faces extinction. the urgent necessity for effective conservation efforts to protect the european mink is accepted by the governmenta ...200818179633
mhc class ii variation in the endangered european mink mustela lutreola (l. 1761)--consequences for species conservation.the polymorphic major histocompatibility complex (mhc) has gained a specific relevance in pathogen resistance and mate choice. particularly the antigen-binding site (abs), encoded by exon 2 of the drb class ii gene, exhibits numerous alleles and extensive sequence variations between alleles. a lack of mhc variability has attributed to instances such as bottleneck effects or relaxed selection pressure and has a certain impact on the long-term viability of the species concerned. as a result of ser ...200919263000
the causes of the low breeding success of european mink (mustela lutreola) in captivity.high among-individual variation in mating success often causes problems in conservation breeding programs. this is also the case for critically endangered european mink and may jeopardize the long-term maintenance of the species' genetic diversity under the european mink eep program. in this study, breeding success of wild and captive born european minks at tallinn zoological garden are compared, and the mating behavior of the males is analyzed. results show that wild born males successfully mat ...201323426800
situation and context impacts the expression of personality: the influence of breeding season and test context.non-human animal personality is defined as consistent behavioural differences across time and situations/contexts. behaviours are, however, often plastic and to explain how plasticity and personality may coexist an adaptive framework has been developed. still, there is little information on how personality is impacted by situations and contexts on an individual level. we investigated this in the european mink (mustela lutreola) by performing a set of five experiments in two situations consisting ...201323988476

noninvasive monitoring of female reproductive hormone metabolites in the endangered european mink (mustela lutreola).this study examined the reproductive physiology of female european mink (mustela lutreola) to augment the available information on estrus, ovulation, and pregnancy with the long-term goal of supporting ex situ breeding management of this highly endangered species. fecal reproductive hormone metabolites were measured using eias for estrogen and 20-oxo-pregnane metabolites. seasonal hormone profiles were established. a comparison of hormone fluctuations in pregnant and nonpregnant females showed t ...201526324114
effects of environmental enrichment and stereotypic behavior on maternal behavior and infant viability in a model carnivore, the american mink (neovison vison).in several species, stress compromises maternal behaviors that are important for infant viability (e.g. licking and grooming). understanding how stress in captivity affects maternal behavior could therefore be beneficial, especially for carnivores in zoos and breeding centers where infant mortality is often high. we used a model carnivore--american mink--to test two hypotheses, namely that maternal investment and/or behavior is i. improved by environmental enrichment; and ii. compromised by ster ...201626536278
the influence of spatiotemporal conditions and personality on survival in reintroductions-evolutionary implications.personality exists in non-human animals and can impact fitness. there is, however, a shortage of empirical studies in certain areas within the field, and fundamental evolutionary theory on personality remains largely untested. for example, little is known on how variation in personality is maintained over evolutionary time. theory suggests that fluctuating selection pressures due to spatiotemporal variation in conditions, e.g. food availability, is a possible mechanism and a few studies have sho ...201727722799
reproductive parameters of critically endangered european mink (mustela lutreola) in captivity.founding captive populations is often the last chance for saving endangered species from extinction. ensuring successful reproduction is typically most critical for the maintenance of captive populations, with purposeful selection of individuals for breeding being one of the crucial aspects. comparable cross-species data on the determinants of reproduction success are most useful for solving problems in captive species programs. in the present study, we provide an overview of a 20-year captive b ...201728412080

phylogenetic relationships and divergence times among mustelids (mammalia: carnivora) based on nucleotide sequences of the nuclear interphotoreceptor retinoid binding protein and mitochondrial cytochrome b genes.phylogenetic relationships among 20 species-group taxa of mustelidae, representing mustelinae (mustela, martes, gulo), lutrinae (enhydra), and melinae (meles), were examined using nucleotide sequences of the nuclear interphotoreceptor retinoid binding protein (irbp) and mitochondrial cytochrome b genes. neighbor-joining and maximum-parsimony phylogenetic analyses on these genes separately and combined were conducted. while irbp performed better than cytochrome b in recovering more-inclusive clad ...200312655187
neoplasms and novel gammaherpesviruses in critically endangered captive european minks (mustela lutreola).the european mink (mustela lutreola) is a riparian mustelid, considered one of the most endangered carnivores in the world. alpha, beta and gammaherpesviruses described in mustelids have been occasionally associated with different pathological processes. however, there is no information about the herpesviruses species infecting european minks. in this study, 141 samples of swabs (oral, conjunctival, anal), faeces and tissues from 23 animals were analysed for herpesvirus (hv) using a pan-hv-pcr a ...202032619314
seroprevalence and b1 gene genotyping of toxoplasma gondii in farmed european mink in the republic of tatarstan, russia.toxoplasma gondii is a protozoan parasite that infects almost all species of mammals and birds, including fur-bearing animals. however, the prevalence of t. gondii among russian fur-bearing animals is unknown. in this study, the seroprevalence of t. gondii in european mink in russia was investigated. in total, 100, 119 and 61 serum samples were collected from a fur farm, located in the republic of tatarstan, russia, in autumn 2016, 2017 and 2018, respectively. the seroprevalence of t. gondii in ...202032004751
severe parasitism by versteria mustelae (gmelin, 1790) in the critically endangered european mink mustela lutreola (linnaeus, 1761) in spain.the riparian european mink (mustela lutreola), currently surviving in only three unconnected sites in europe, is now listed as a critically endangered species in the iucn red list of threatened species. habitat loss and degradation, anthropogenic mortality, interaction with the feral american mink (neovison vison), and infectious diseases are among the main causes of its decline. in the spanish foral community of navarra, where the highest density of m. lutreola in its western population has bee ...201830182257
[trichophyton mentagrophytes-from snow leopard to man : a molecular approach for uncovering the chain of infection].sources of infection for trichophyton (t.) mentagrophytes-a zoophilic dermatophyte-comprise pet rodents (guinea pigs, mice, rabbits) and sometimes cats. human infections due to dermatophytes after contact with zoo animals, however, are extreme rare. four zoo keepers from basel zoo were diagnosed to suffer from tinea manus and tinea corporis due to t. mentagrophytes. the 22-year-old daughter of one zoo keeper was also infected with tinea corporis after having worked in the snow leopard section fo ...201830120492
