Determining breeding status in green anacondas (Eunectes murinus): a condition index assuming isometry
JA Rivas - South American Journal of Herpetology, 2023 - BioOne
Capital breeders are animals that breed with the stored energy they have gathered prior to
the reproductive event. The amount of energy stored by a given individual can be quantified …

The intensity of sexual selection, body size and reproductive success in a mating system with male–male combat: is bigger better?
Body size is a key selected trait in many animal systems: larger size is sexually selected for
in males because it confers a reproductive advantage during contest competition for access …
