摘要: Few researches have been carried out on wild populations of small carnivores involving animals live trapping. Problems in field data collection make spatial and reproductive dynamics these species still not understood. This research used about only 14 trapped individuals, because the quoted problems, nevertheless results showed important preliminary considerations this topic. In study, genetic microsatellite methodology applied to natural weasel population produced data kinship dispersal patterns. All the 11 analyzed loci were found polymorphic, with an average number alleles per locus 5.36; estimated expected heterozygosity He (0.62) is at highest end range of other Mustela species. No significant deviations from Hardy-Weinberg equilibrium (p >=0.05). The analysis no full siblings one parent-off-spring pair: so 1.09% total possible pair wise comparisons (91) close genetic kinship. proportion related from the sampled was 14,2%
