The scientific understanding of arthropod phylogeny and evolution has changed significantly
in recent decades. One of the most momentous alterations involved crustaceans, which are …

The morphology of Isoxys auritus Jiang, 1982 is reinterpreted in the light of abundant new
specimens from the Early Cambrian Chengjiang biota, South China. I. auritus was a …

While equal ratios of males and females are normal, crustacean sex ratios are frequently
biased. Here I review potential reasons for sex ratio biases in animals, and evaluate how …

Sexual dimorphism can evolve in response to sex-specific selection pressures that vary
across habitats. We studied sexual differences in subterranean amphipods Niphargus living …

Sex allocation theory predicts that the proportion of daughters to sons will evolve in
response to ecological conditions that determine the costs and benefits of producing each …

Two new species of Brueelia are described and illustrated. These new species and their
type hosts are: Brueelia sueta ex Pharomachrus pavoninus (Spix, 1824), the Pavonine …

While in most species the adult sex ratio is around 1: 1, it can be strongly skewed in some
species; some of this can be explained by ecological conditions and limits to dispersal. We …

The bivalved arthropod Branchiocaris? yunnanensis Hou, 1987 is redescribed on the basis
of new fossil material from the early Cambrian Chengjiang biota, South China. In total, 81 …
