Surprisingly, extant populations of the giant panda display average to high levels of CR and microsatellite diversity compared with other bear species, suggesting that the panda is not a species at an evolutionary "dead end," but in common with other large carnivores, has suffered demographically at the hands of human pressure.
Rapid and recent diversification patterns in Anseriformes birds: Inferred from molecular phylogeny and diversification analyses
Both molecular phylogeny and diversification analyses results support that Anseriformes birds underwent rapid and recent diversification in their evolutionary history, especially in modern ducks, which show extreme diversification during the Plio-Pleistocene.
Species Delimitation in the Genus Moschus (Ruminantia: Moschidae) and Its High-Plateau Origin
Phylogenetic analysis and molecular dating showed that the ancestor of the present Moschidae originates from Tibetan Plateau which suggested that the evolution of Moschus was prompted by the most intense orogenic movement of the Tibetan PlateAU during the Pliocene age, and alternating glacial-interglacial geological eras.
Complete sequence and gene organization of the mitochondrial genome of Asio flammeus (Strigiformes, strigidae)
The molecular-based phylogeny showed that the mitochondrial genome of Asio flammeus acted as the sister group to A. capensis and the supported Asio was the monophyletic group.
The Phylogeography and Population Demography of the Yunnan Caecilian (Ichthyophis bannanicus): Massive Rivers as Barriers to Gene Flow
The Bayesian simulations of population history based on microsatellite data pinpointed population decline in all populations since 19,123 to 1,029 years ago, demonstrating a significant influence of anthropogenic habitat alteration on I. bannanicus.
How much genetic variation is stored in the endangered and fragmented shrub Tetraena mongolica Maxim?
The results suggest that the Yellow River and Zhuozi Mountain range may not prevent pollination between populations, and it is surmised that the population demography of T. mongolica was likely to have been affected by early mankind activities.
Yangtze River, an insignificant genetic boundary in tufted deer (Elaphodus cephalophus): the evidence from a first population genetics study
The results indicated that the Yangtze River may not act as an effective barrier to gene flow in the tufted deer, and the population demography of the tuFTed deer was likely affected by Pleistocene climate fluctuations and ancient human activities.
Near-complete phylogeny of extant Crocodylia (Reptilia) using mitogenome-based data
This study proves that the diversification rate within Crocodylia began to increase from the Late Eocene and two diversification peak periods of Croc Codylia are disclosed, which is roughly consistent with the estimated crocodylian species richness through time.
The mitochondrial genome of pin-tailed snipe Gallinago stenura, and its implications for the phylogeny of Charadriiformes
Predicted secondary structures of tRNAs indicate that the sequences and structures of anticodon, amino acceptor, and TψC arms are highly conserved, and most nucleotide variation is restricted to dihydrouridine arms with obvious indel polymorphisms.
The reanalysis of biogeography of the Asian tree frog, Rhacophorus (Anura: Rhacophoridae): geographic shifts and climatic change influenced the dispersal process and diversification
The results of molecular dating, ancestral area reconstructions and LTT think the geographic shifts, the staged rapid rises of the Tibetan Plateau with parallel climatic changes and reinforcement of the Asian monsoons, possibly prompted a burst of diversification in Rhacophorus.
