TLDR
Investigation of genetic diversity among populations of the Japanese giant flying squirrel Petaurista leucogenys found that ancestral populations of this group recently expanded their distribution in a short time, possibly after the last glacial stage.Abstract:
To investigate genetic diversity among populations of the Japanese giant flying squirrel Petaurista leucogenys, the mitochondrial DNA control region sequences (1,052–1,054 bases) were determined in 37 specimens from 17 localities on the Honshu, Shikoku, and Kyushu Islands of Japan. Of the 37 animals examined, 24 haplotypes were identified. All haplotypes from Kyushu consisted of 1,052 bases, whereas those from Honshu and Shikoku consisted of 1,054 bases including two insertions, except for three haplotypes (which had 1,052 or 1,053 bases). Phylogenetic relationships reconstructed using neighbor-joining and maximum parsimony methods indicated that P. leucogenys is essentially separated into three major lineages: Group A consisting of a single haplotype from Kyushu, Group B consisting of some haplotypes from Kyushu and one haplotype from Honshu, and Group C consisting mostly of haplotypes from Honshu and Shikoku. Animals with the Kyushu haplotypes were split into two lineages (Groups A and B), sugg...read more

TL;DR: This book is based on a symposium organized by the Entomological Society of America in 1980 and will prove to be an important book in bringing together recent research on the mating systems of orthopterans, and discussing their behaviour in the light of current theory in behavioura].

The influence of climatic oscillations during the Quaternary Era on the genetic structure of Asian black bears in Japan.
TL;DR: The extant genetic structure of the Asian black bear populations arose as follows: first, populations became small and genetic drift decreased genetic diversity in the northern area during the last glacial period, whereas large continuous populations existed in the southern part of central Japan.

TL;DR: Nesting colonies of Japanese loggerheads are genetically distinct and that Japanese females show precise natal homing on an ecological time scale, indicating that all loggerheads inhabit the North Pacific are derived from Japanese beaches.

Estimating the molecular evolutionary rates of mitochondrial genes referring to Quaternary ice age events with inferred population expansions and dispersals in Japanese Apodemus
TL;DR: The faster and slower evolutionary rates of Cytb can account for divergences associated with the last and earlier glacial maxima, respectively, in the phylogenetic inference of murine rodents.

Genetic diversity and population divergence in fragmented habitats: Conservation of Idaho ground squirrels
TL;DR: Habitat restoration appears to be the most desirable conservation strategy for NIDGS populations and low genetic diversity observed in SIDGS may warrant supplementation of isolated populations through translocations or captive breeding to mitigate further loss of genetic variability.

Confidence limits on phylogenies: an approach using the bootstrap.
TL;DR: The recently‐developed statistical method known as the “bootstrap” can be used to place confidence intervals on phylogenies and shows significant evidence for a group if it is defined by three or more characters.

A simple method for estimating evolutionary rates of base substitutions through comparative studies of nucleotide sequences.
TL;DR: Some examples were worked out using reported globin sequences to show that synonymous substitutions occur at much higher rates than amino acid-altering substitutions in evolution.
