Why do some animals mate with one partner rather than many? Here, I investigate factors
related to (i) spatial constraints (habitat limitation, mate availability),(ii) time constraints …

Size-selective male fisheries may result in sperm limitation whereby the number of sperm is
insufficient to fertilize all oöcytes produced by females. In eubrachyuran crabs, females have …

Elucidating the processes responsible for maintaining the population connectivity of marine
benthic species mediated by larval dispersal remains a fundamental question in marine …

Crustacean fisheries often preferentially or exclusively harvest males, resulting in selection
that alters sex ratios in fished populations. Sex-biased fisheries may occur when males are …

We examined the female reproductive system of the yellowline arrow crab Stenorhynchus
seticornis by means of histological and histochemical techniques. Mature specimens …

Observations of male mate choice are increasingly common, even in species with traditional
sex roles. In addition, female traits that bear the hallmarks of secondary sexual characters …

When mates are encountered sequentially, each encounter involves a decision whether to
reject the current suitor and risk not finding a better mate, or to accept them despite their …

Reproduction involves high energetic costs which are related to behaviour and gamete
production. In females energy allocation to gamete production has been well documented …

Selective harvest of male blue crabs Callinectes sapidus can reduce the operational sex
ratio and alter male mating history and behaviors, reducing the quantity of sperm females …

Many marine species are under high fishing pressure, which can cause alterations in their
mating systems and the structure of their populations. The spiny spider crab Maja …
