Summer home range, habitat use, movements, and activity patterns of river otters (Lontra canadensis) in the Killbuck Watershed, northeastern Ohio

摘要: Summer Home Range, Habitat Use, Movements, and Activity Patterns of River Otters (Lontra canadensis) in the Killbuck Watershed, Northeastern Ohio David A. Helon otters canadensis), one most aquatic Mustelids, are important components riparian systems an fur-bearing species. Several studies evaluating post-release survival movements have been conducted; however, there deficient long-term to determine status these river otter populations once established. During 2002 2003m 16 (7 female, 9 male) were trapped radio-tagged. Overall, mean female home range size was 802.4 ha male 1,101.7 ha. Mean similar between genders 2002, but greater for males than females during 2003. I found differences habitat use by based on compositional analysis a chi-square test. Marsh used frequently. movement distance ( × = 1.8 km) less (× 5.2 km). active 2201 1000 least 1001 1600 hours. This knowledge can be other parts upper Midwest aid management.
