Abstract As George Williams pointed out in 1975, although evolutionary explanations, based
on selection acting on individuals, have been developed for the advantages of simultaneous …

We used a combined analysis of one nuclear (28S rDNA) and three mitochondrial markers
(COI, 12S rDNA, 16S rDNA) to infer the molecular phylogeny of the Notostraca, represented …

Barnacles are exceptional in having various sexual systems (androdioecy, hermaphroditism,
dioecy) and with a high morphological diversity of males, though these are always minute …

'Living fossils', a phrase first coined by Darwin, are defined as species with limited recent
diversification and high morphological stasis over long periods of evolutionary time …

Since the development of the modular visualization environment, the users of such gen eral
software have had to face the problems of file input Simply put the range and complexity of …

This chapter compares two sexual systems: hermaphroditism (each individual can produce
gametes of either sex) and gonochorism (each individual produces gametes of only one of …

Australia has a very rich and diverse large branchiopod fauna with approximately 140
described or provisionally delimited species, but only one species of Triops, Triops …

Transitions in sexual system and reproductive mode may affect the course of sex
chromosome evolution, for instance by altering the strength of sexually antagonistic …

In this chapter, the diversity of sexual systems in the infraorder Caridea is summarized.
Caridean shrimps exhibit six different sexual systems: gonochorism (separate sexes), strict …
