Cím:	Effects of extensive fishpond management and human disturbance factors on Eurasian otter (Lutra lutra L. 1758) populations in Eastern Europe / Juhász Krisztina, Lukács Balázs András, Perpék Mónika, Nagy Sándor Alex, Végvári Zsolt
Dátum:	2013
Megjegyzések:	Wetland losses related to human activities in the past decades have caused heavy decline in thepopulation of the Eurasian otter (Lutra lutra Linnaeus) throughout Europe. As otters are often used as flagshipspecies for wetland conservation programmes, the understanding of their response to human disturbanceand environmental factors is essential to fine-tune conservation tools for managing artificial water bodies.In this study we estimate which wetland characteristics and human factors to what extent drive the spatialdistribution of otters. We investigated factors related to the habitat selection of Eurasian otters betweenDecember 2004 and January 2007 on 31 fishponds in the Hortobágy National Park, Eastern Hungary. Wehave shown that otter habitat selection is primarily governed by both disturbance-related characteristics andvegetation properties of fishponds, and not by humans. Moreover, we did not find the effects of artificialfisheries inputs or hunting pressures. Fishponds far from human settlements with large reed islands anddykes with trees are the key habitats for Eurasian otters. However, the presence of adjacent forests and grazingareas negatively affect the otter sign densities in fishponds.
