The Sprainting Behavior and Habitat Preference of the Eurasian Otter Lutra lutra Along a Montane Stream in South Korea

摘要: Although the Korean population of Eurasian otter (Lutra lutra) was designated as an endangered species, habitat and basic ecology otters have been rarely known. To ascertain sprainting behavior in freshwater investigate preferences, surveys along Ungok River Gyeongsangbuk-do, South Korea, were conducted for a 12-month period during 2002 2003. Seasonal fluctuations number spraints sites river identified. The peaked March. General linear models indicated site-dependency numbers sites. general mixed model that (or site) positively correlated with vegetations on riverbanks depth. human impact width significantly related to spraints, they did not show significant relationship Despite several coincidence studies Europe, by montane Korea suggested differences regional spatial level. This ecological information will assist investigation size help management otters.
