Phylogenomic analyses of hamsters (Cricetinae) inferred from GBS data and mitochondrial genomes.

Accurate species delimitation and identification is crucial for species conservation, providing a foundation for studies on evolutionary biology, ecology, and essentially all biological disciplines. The subfamily Cricetinae (Cricetidae, Rodentia), known as hamsters, is widely distributed in the Palearctic region. At present, there are nine genera and 18 species of hamsters are recognized worldwide, although the taxonomic status of certain taxa remains unclear.

Uncovering widespread Anthropocene dietary shifts in Chinese large mammalian herbivores.

The Anthropocene's human-dominated habitat expansion endangers global biodiversity. However, large mammalian herbivores experienced few extinctions during the 20th century, hinting at potentially overlooked ecological responses of a group sensitive to global change. Using dental microwear as a proxy, we studied large herbivore dietary niches over a century across mainland China before (1880s-1910s) and after (1970s-1990s) the human population explosion.

DNA barcoding and species delimitation of Chaitophorinae (Hemiptera, Aphididae).

Chaitophorinae aphids are widespread across Eurasia and North America, and include some important agricultural and horticultural pests. So, accurate rapid species identification is very important. Here, we used three mitochondrial genes and one endosymbiont gene to calculate and analyze the genetic distances within different datasets.

Review of the aphid genus Aspidophorodon Verma, 1967 with descriptions of three new species from China (Hemiptera: Aphididae: Aphidinae).

The aphid genus Aspidophorodon Verma, 1967 is reviewed, with descriptions of three new species from China, namely Aspidophorodon (Aspidophorodon) cornuatus Qiao sp. nov., Aspidophorodon (Aspidophorodon) musaicus Qiao sp.
