Journal ArticleDOI
Phylogeography of the Russian flying squirrel (Pteromys volans): implication of refugia theory in arboreal small mammal of Eurasia.
TL;DR: A phylogeographical study of the Russian flying squirrel (Pteromys volans) was carried out using the complete mitochondrial (mt) cytochrome b gene sequences with special reference to the refugia theory for the arboreal traits of this species as mentioned in this paper.
Journal ArticleDOI
Seasonal variation of flight initiation distance in Eurasian red squirrels in urban versus rural habitat
TL;DR: Comparing the seasonal difference of flight initiation distance in Eurasian red squirrels Sciurus vulgaris between urban and rural areas in the Tokachi region, Hokkaido, Japan suggests that continuous supplementary feeding may have buffered the seasonality in anti-predator response.
Journal ArticleDOI
Decreased vigilance or habituation to humans? Mechanisms on increased boldness in urban animals
TL;DR: A simple framework to separate the two processes using two flight distance measures toward different approaching threats is proposed and suggests that, although urban individuals showed reduced vigilance, they could still assess different risk levels.
Journal ArticleDOI
Phylogenetic Relationships among Six Flying Squirrel Gener,a Inferred from Mitochondrial Cytochrome b Gene Sequences
TL;DR: Molecular phylogenetic trees constructed by neighbor-joining and maximum likelihood methods strongly indicated the closer relationship between Hylopetes and Petinomys with 100% bootstrap values, suggesting the early radiation in the evolution of flying squirrels.
Journal ArticleDOI
Relative importance of the environmental factors at site and landscape scales for bats along the riparian zone
TL;DR: In this paper, the authors investigated the relative importance of environmental factors on bat occurrence and abundance in riparian zones at site and landscape scales, and showed that streams adjacent to a well-developed broadleaved deciduous forest are important for night habitats of many bat species.
