Subject:
Martes; genetic variation; genotype; lakes; microsatellite repeats; mountains; population structure; rivers; Japan; Russia
Abstract:
... To assess the genetic variation and population structure of the sable Martes zibellina on eastern Hokkaido, Japan, we analyzed genotypes of 12 microsatellite loci on 48 individuals. Genotypes for all individuals examined were found to be different from each other. Mean observed and expected heterozygosites and allelic richness were calculated to be 0.52 (0.02–0.80), 0.58 (0.02– 0.79) and 5.49, res ...

Abstract:
... Rivers are habitats favored by insectivorous bats. The Japanese large-footed bat (Myotis macrodactylus) is one of such species strongly associated with rivers. To clarify the population structure and migration pattern of M. macrodactylus, mitochondrial DNA (mtDNA) phylogeography was investigated in 15 subpopulations along three rivers (Tokachi, Ishikari and Teshio Rivers) on Hokkaido Island, north ...

Subject:
Callichthyidae; Cichlidae; Lontra longicaudis; diet; ecology; feces; fish; foraging; rivers; seasonal variation; Brazil
Abstract:
... The scats of Lontra longicaudis are easily recognized in the field and provide basic information about its foraging ecology. Two questions were addressed regarding its diet: (I) Does the composition of prey vary temporally? (II) Does the dietary breath vary seasonally? We answered these questions based on scatological analyses. We carried out 12 field trips, once per month for a year, to collect s ...

Abstract:
... The diet and feeding habits of Eurasian otters (Lutra lutra) were studied by spraint analysis over a one year period on the four sections of the Jajrood River, eastern Tehran. Two methods were used to estimate the proportions of different prey consumed: frequency of occurrence and score-bulk estimate. The number of prey categories in a spraint varied between one and four. Fish, crabs, birds and in ...

A total of 852 sexually mature specimens of 24–44 local populations were grouped into 5–11 regions by countries, provinces of China, running directions of big rivers in south-western China and Myanmar, or islands. In A. peninsulae, significant pos ...

Abstract:
... Evolutionary history of Callosciurus squirrel species seems affected by geographical isolation by huge rivers in Southeast Asia. Geographical isolation by rivers may have influenced phylogeographical structure between and within Callosciurus species. In Sundaland, Southeast Asia, however, phylogeographical structure within Callosciurus species may be explained by geographical isolation among islan ...

Abstract:
... Accurate determination of the abundance and distribution of animals, particularly endangered species, is a fundamental requirement for understanding their ecology and has important applications for their conservation. In Bornean flooded forests, various approaches have previously been used to conduct primate census, including foot-based land surveys and boat-based river surveys at different times ...

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 ...

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 ...

Abstract:
... Taiwan was considered rabies-free for > 50 years until the disease reemerged in its ferret badger population (Melogale moschata) in 2013. Although it is still expanding slowly northward in eastern Taiwan, its spread in the west has thus far been halted by the Da-An River. To prevent diffusion of rabies, an immunization zone should be established along the epidemic boundary before further rabies ex ...

Abstract:
... The sika deer population on Yakushima Island exhibits high genetic diversity despite the small size of the island. We hypothesized that the high genetic diversity of the population had been maintained by the population structure, which included several subpopulations among which gene flow was limited. To test this hypothesis, we analyzed the spatial genetic structure of the population using 12 mic ...
