Subject:
concrete; dams (hydrology); rivers; sediments; shrews; streams; surveys; Japan
Abstract:
... The concrete walls of check dams are considered a physical barrier for aquatic and semiaquatic animals that inhabit mountain streams. Traveling behaviors around concrete check dams by the Japanese water shrew Chimarrogale platycephalus, a semi-aquatic mammal, were directly observed via radio-tracking in Kamikoshi Stream in central Honshu, Japan. Traveling behaviors were mainly observed on the wet ...

Subject:
agricultural land; cameras; crop damage; deer; fences; habituation; rivers; urine; wolves
Abstract:
... Fences are the most effective defenses against crop damage by deer. If properly constructed and maintained, fences mitigate crop damage. However, it is difficult to enclose farmland completely when a fence crosses a river. This study evaluated the effectiveness of olfactory (wolf urine), visual (flashlight), and sound deterrents against deer at the intersection of river and fence. These deterrents ...

Lutra lutra; anthropogenic activities; endangered species; freshwater; habitat conservation; habitat preferences; habitats; linear models; population size; riparian areas; rivers; seasonal variation; streams; surveys; Europe; South Korea
Abstract:
... Although the Korean population of Eurasian otter (Lutra lutra) was designated as an endangered species, habitat and basic ecology of Korean otters have been rarely known. To ascertain sprainting behavior of the Eurasian otter in the freshwater habitat and investigate the habitat preferences, otter surveys along the Ungok River in Gyeongsangbuk-do, South Korea, were conducted for a 12-month period ...
