Sex-specific metamorphosis of cypris larvae in the androdioecious barnacle Scalpellum scalpellum (Crustacea: Cirripedia: Thoracica) and its implications for the adaptive evolution of dwarf males. [PDF]
Androdioecy (co-existence of hermaphrodites and dwarf males) is a fascinating yet poorly understood phenomenon. The pedunculated barnacle Scalpellum scalpellum is an emerging model species for the system. In S.

Discriminating between the effects of founding events and reproductive mode on the genetic structure of Triops populations (Branchiopoda: Notostraca). [PDF]
Crustaceans that initially colonize a freshwater temporary pond can strongly bias the subsequent genetic composition of the population, causing nearby populations to be genetically distinct.

Reproductive biology of Talisia esculenta (Cambess.) Radlk. (Sapindaceae) [PDF]
The family Sapindaceae comprises species with different reproductive strategies and sexual systems; however, dioecy is rarer and has been little investigated in tree species. We analyzed the reproductive biology of Talisia esculenta (Cambess.) Radlk.

Pappea capensis: monoecious, dioecious or androdioecious?
Pappea capensis used to be regarded a dioecious plant. In this short communication, evidence is provided which shows that Pappea capensis is monoecious with a distinct male phase followed by a distinct female phase.

Evolution of outcrossing in experimental populations of Caenorhabditis elegans.
Caenorhabditis elegans can reproduce exclusively by self-fertilization. Yet, males can be maintained in laboratory populations, a phenomenon that continues to puzzle biologists.

Androdioecy Inferred in the Clam Shrimp Eulimnadia Agassizii (Spinicaudata: Limnadiidae) [PDF]
Abstract Androdioecy (mixtures of males and hermaphrodites) is a rare mating system in both the plant and animal kingdoms. Androdioecy has been described in three branchiopod species, and is best known from the clam shrimp Eulimnadia texana Packard.

The Maintenance of Gynodioecy and Androdioecy in a Metapopulation [PDF]
Males and females are at a selective disadvantage relative to hermaphrodites (cosexuals) in species with a colonizing habit, as only cosexuals are able to establish new colonies on their own. The implications of this disadvantage are assessed by means of a computer model of metapopulation dynamics, in which individual colonies are established through ...
