Pea crabs, Dissodactylus primitivus, inhabit multiple echinoid (heart urchin) hosts. Male and
female crabs move among hosts in search for mates, and both sexes mate multiple times …

The mating systems of symbiotic crustaceans vary broadly, ranging from monogamy to
polygamy to promiscuity. This disparity in mating systems coupled with wide differences in …

Explanations for the evolution of male-biased size dimorphism (MBSSD) traditionally focus
on male competition and female choice, overlooking the alternative that larger males may be …

For polyandrous species where females have sperm storage structures, males develop
several strategies to avoid sperm competition and thus to maximize the number of eggs …

The use of alternative male mating tactics can determine the strength of sexual selection on
male traits and have implications for sexual dimorphism. We examined size-based mating …

Populations of a single species may vary substantially in sexually selected traits. However,
the majority of studies investigating such variation across populations have focused on traits …

Brachyuran crabs of the family Pinnotheridae De Haan are a classic example of symbiotic
lifestyle. Here, we described the host‐use pattern, relative growth and sexual dimorphism of …

The fiddler crab Uca mjoebergi mates both underground in male-defended burrows and on
the surface near female-defended burrows. The reproductive tract of Uca species facilitates …

While the four species of horseshoe crabs share many common reproductive traits with
respect to their reproductive systems, they do differ with respect to their mating behavior …

Consistent differences among females in mating with one (monandrous) or multiple males
(polyandrous) may be a product of male behavior or may reveal the existence of female …
