Genetic structure and evidence for recent population decline in Eurasian otter populations in the Czech and Slovak Republics: implications for conservation

Popis výsledku v původním jazyce

Over the latter part of the 20th century, Eurasian otter Lutra lutra populations suffered dramatic declines, resulting in extinction or fragmentation of many populations. Part of the Czech otter population became totally isolated while the Slovak population remained partly connected to the relatively continuous central and eastern European otter distribution range. We examined the genetic structure and past demographic history of otters in the Czech and Slovak Republics, using microsatellites amplifiedfrom DNA extracted from tissue and faecal samples. A relatively high level of genetic differentiation was found between the Czech and Slovak populations (FST=0.154), supported by a perfect assignment in Bayesian cluster analysis. Evidence for recent population bottleneck was found by two different programmes in both populations. The results confirm that otter populations remain vulnerable to any violent demographic change and should remain a strongly protected species in both countries.
