Occurrence, food habits, and activity patterns of Eurasian otters Lutra lutra in northwestern Greece: implications for research and conservation

摘要: Eurasian otters (Lutra lutra) have experienced dramatic population declines that resulted in the extirpation of species from several parts their original distribution and led most European countries to initiate systematic monitoring management efforts. We present results a long-term study (2010–2012) this endangered northwestern Greece. Occurrence at Lakes Zazari Himaditida was assessed using standard sign surveys, dietary habits were investigated through spraint analysis, activity patterns studied automatic infrared cameras. Otter occurrence widespread throughout area continuous during period included presence family group. diet high proportion birds, nocturnal. More efforts development Species Action Plan are necessary ensure survival otter
