We propose a practical concept that distinguishes the particular kind of weaponry that has
evolved to be used in combat between individuals of the same species and sex, which we …

Comprising extant species, Macrobrachium is the most speciose caridean genus in
Palaemonidae. It is generally considered as a monophyletic clade that lives exclusively in …

We report on the population dynamics and reproductive traits of an ornamental crustacean,
the spotted porcelain crab Porcellana sayana. Reproductive biology was examined between …

Some crustaceans show variations of their reproductive biology within their geographical
distribution, and knowledge about such variations is important for the comprehension of their …

Understanding variation in trait allometry and the drivers of variation in sexually selected
traits is a major theme in evolutionary biology. The static allometries of sexually selected …

The life history of insular gecarcinid crabs is divided into a marine larval and an adult phase,
adapted to the terrestrial environment. As adults, individuals migrate seasonally to locations …

Theory predicts that monogamy is adaptive in resource-specialist symbiotic crustaceans
inhabiting relatively small and morphologically simple hosts in tropical environments where …

Decapod crustaceans develop secondary sexual structures, such as large chelipeds for
weaponry and/or display in males and a wider pleon for incubating eggs in females. These …

Hard-shell-mating is the typical way that semi-terrestrial and terrestrial crabs copulate, when
females reproduce with a hard carapace during the intermoult period and the couples have …

Contesting scarce resources can trigger the evolution of specialized morphological
structures (ie, animal weapons). While most research focus on male weapons, females …
