Insect male genitalia are among the fastest evolving structures of animals. Studying these
changes among closely related species represents a powerful approach to dissect …

Rapid speciation events, with taxa generated over a short time period, are among the most
investigated biological phenomena. However, molecular systematics often reveals …

Advances in phylogenomics contribute toward resolving long-standing evolutionary
questions. Notwithstanding, genetic diversity contained within more than a billion biological …

Aim Past glacial cycles have generated lineage diversity in alpine habitats, acting as a
climate‐driven species pump. It is not clear how much this process contributes to ecological …

Body shape and size diversity and their evolutionary rates correlate with species richness at
the macroevolutionary scale. However, the molecular genetic mechanisms underlying the …

Animal body size is involved in reproduction in various ways. Carabus japonicus exhibits
considerable variation in adult body size across geographical locations depending on the …

The monophyletic status of the genus Oreina as well as its phylogenetic relation to the
closely related genera Chrysolina, Crosita and Cyrtonus has been debated for several …

Genital morphology reveals rapid diversification among species, and species-specific
divergence in genital morphology may result in reproductive isolation and promote …

Extensive research in evolutionary biology has focused on the exaggeration of sexual traits;
however, the developmental basis of exaggerated sexual traits has only been determined in …

Simple Summary Taxonomic studies on a polymorphic species inhabiting a region with
relatively uniform environmental conditions (eg, the Arctic) should involve an integrative …
