Distribution and habitat models of the Eurasian otter, Lutra lutra, in South Korea

摘要: Eastern populations of the Eurasian otter (Lutra lutra) have declined throughout Asia. Although South Korean government designated as an Endangered Species and Natural Monument, limited information exists on distribution habitat this top predator in riparian ecosystems at terminus its distribution. We documented modeled species using sign survey data collected 2009 2010. analyzed presence with 21 raster sets environmental niche modeling. evaluated 31 variables explanatory for logistic regression models that considered detection non-detection data. detected 83% (3,288 3,957) sites within 63% (680 1,074) cells. In our MaxEnt presence-only model, land cover type was main contributing factor to predicting suitability, secondary influences from isothermality, precipitation wettest month, elevation, temperature seasonality. Water quality human disturbance were significantly associated occurrence based model included Direct measures activity, such traffic volume price, better predictors than stationary factors density buildings. Our results suggest otters humans can coexist highly populated areas. characteristics Korea will assist management recovery projects natural anthropogenic environments.
