Habitat selection by river otters (Lontra canadensis) under contrasting land-use regimes

摘要: Habitat preferences of river otters (Lontra canadensis (Schreber, 1777)) are well known, but because most studies were conducted in regions with markedly low or high levels anthropogenic disturbances, it is not known how their habitat usage affected by varied disturbances and land-use regimes on a regional scale. We studied use eastern New Brunswick, Canada, an area having both protected disturbed riparian habitats. Using long-range winter transects, we documented activity-sign distribution along riverbanks relation to 12 factors 9 categories disturbances. variables at site activity signs stations 500 m intervals. used logistical regressions Akaike’s information criterion information–theoretic approach compare models determine the important involved.
