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 کاملMating behavior and the evolution of sperm design.
Sperm are the most diverse of all animal cell types, and much of the diversity in sperm design is thought to reflect adaptations to the highly variable conditions under which sperm function and compete to achieve fertilization. Recent work has shown that these conditions often evolve rapidly as a consequence of multiple mating, suggesting a role for sexual selection and sexual conflict in the e...
متن کاملEarly male reproductive advantage, multiple paternity and sperm storage in an amphibian aggregate breeder.
We tested whether the order in which males encounter females affects reproductive fitness in spotted salamanders (Ambystoma maculatum). Using mating chambers in the field, we allowed one male access to a female before a second male. We then used four microsatellite markers in paternity analyses of the resulting larvae. First males sired a significantly larger number of offspring than second mal...
متن کاملFunction of copulatory plugs in house mice: Mating behavior and paternity outcomes of rival males
Polyandry is widespread across animal taxa, and subjects males to intense post-copulatory sexual selection which favors adaptations that enhance a male’s paternity success, either by decreasing the risk of sperm competition and/or by increasing the competitiveness of the ejaculate. Copulatory plugs deposited by males are thought to have evolved in the context of sperm competition. However, expe...
