Turtle mating systems: behavior, sperm storage, and genetic paternity.
As evidenced by the articles in this volume, a recent increase in interest in the mating systems of poikilothermic vertebrates has focused primarily on fishes, a few amphibians, and squamate reptiles. Turtles by contrast have received relatively little attention, yet they display a wide variety of mating behaviors and life-history characteristics that make them excellent candidates for addressi...
متن کاملWhy pair? Evidence of aggregative mating in a socially monogamous marine fish (Siganus doliatus, Siganidae)
Many species live in stable pairs, usually to breed and raise offspring together, but this cannot be assumed. Establishing whether pairing is based on mating, or an alternative cooperative advantage, can be difficult, especially where species show no obvious sexual dimorphism and where the act of reproduction itself is difficult to observe. In the tropical marine fishes known as rabbitfish (Sig...
متن کاملPhylogenetic perspectives on the evolution of functional hermaphroditism in teleost fishes.
Hermaphroditism is taxonomically widespread among teleost fishes and takes on many forms including simultaneous, protogynous, and protandrous hermaphroditism, bidirectional sex change, and androdioecy. The proximate mechanisms that influence the timing, incidence, and forms of hermaphroditism in fishes are supported by numerous theoretical and empirical studies on their mating systems and sexua...
متن کاملGenetic perspectives on the natural history of fish mating systems.
Molecular analyses of bird and mammal populations have shown that social mating systems must be distinguished from genetic mating systems. This distinction is important in fishes also, where the potential for extrapair spawning and intraspecific brood parasitism is especially great. We review studies on fishes that have used molecular markers to document biological parentage and genetic mating ...
متن کاملPatterns of Parental Investment and Sexual Selection in Teleost Fishes: Do They Support Bateman's Principles?
Bateman demonstrated differences in variance for fertility and mating success between the sexes, with males usually having a greater variance than females. Thus in general, male reproductive success increases with number of mates acquired. These results have been referred to as "Bateman's principles" and taken together with other parameters (e.g., relative parental investment) have been propose...
