invaded habitats globally. Ascidians are among the most notorious invaders in these …

Worldwide degradation of coral reef communities has prompted a surge in restoration
efforts. They proceed largely without considering genetic factors because traditionally, coral …

Patterns of population genetic variation have frequently been understood as consequences
of life history covariates such as dispersal ability and breeding systems (eg selfing). For …

The life histories of tropical reef corals (Scleractinia) include two traits that can strongly bias
mating systems towards inbreeding:(1) most species express both sexes simultaneously …

Although sexual antagonism may have played a role in forming some sex chromosome
systems, there appears to be little empirical or theoretical justification in assuming that it is …

The occurrence of self-fertilization in natural populations of hermaphroditic marine
invertebrates has seldom been documented. This is in contrast to plant systems where …

Preface xii an individual can be both a functional male and a female at the same time. In
some of these simultaneous hermaphrodites, an individual may alternate between male and …

Self‐compatible hermaphroditic organisms that mix self‐fertilization and outcrossing are of
great interest for investigating the evolution of mating systems. We investigate the evolution …

In July 2002 the southern hemisphere ascidian Corella eumyota was detected in the
northern hemisphere for the first time, attached to floating docks in two harbours in north …

Self-compatible, hermaphroditic marine invertebrates have the potential to self-fertilize in the
absence of mates or under sperm-limited conditions, and outcross when sperm is available …
