Genetic Diversity of the Eurasian Otter (Lutra lutra) Population in Israel

摘要: The Israeli population of Eurasian otter (Lutra lutra) marks the Palearctic southern boundary species’ distribution in Levant. During 20th century, Israel experienced a dramatic decline due to anthropogenic habitat alterations. Currently, is estimated at about 100 individuals and defined as “Critically Endangered”. aim this research was characterize order determine its genetic diversity fragmentation state for conservation purposes. Monitoring spraint sites during 2000–2011 along active historic regions indicate both stable unstable subpopulations, mainly Jordan River. Four representing 57 individuals, were characterized by 12 microsatellites, previously used European populations. results indicated three subpopulations correlating with geographical regions: Hula Valley, Sea Galilee, Harod Valley. A moderate (F st = 0.087–0.123) found among suggesting sporadic interactions between from distinct locations Rift be very small, demographically remote genetically distinct, harboring unique alleles absent studied Therefore, immediate actions are recommended prevent deterioration isolated, unique, critically endangered Israel.
