The reproductive diversity of extant cartilaginous fishes (class Chondrichthyes) is
extraordinarily broad, reflecting more than 400 million years of evolutionary history. Among …

Understanding mating systems is a pillar of behavioural ecology, placing the complex
interactions between females and males into a reproductive context. The field of multiple …

Sawfishes (Family Pristidae) constitute one of the most threatened families of marine fish,
and substantial management efforts are required to stabilize and recover their populations …

Understanding the fundamental reproductive biology of a species is the first step toward
identifying parameters that are critical for reproduction and for the development of assisted …

Multiple paternity appears to be a common trait of elasmobranch mating systems, with its
occurrence likely driven by convenience, due to females seeking to minimize the stress of …

Reptile embryos have recently been observed moving within the egg in response to
temperature, raising the exciting possibility that embryos might behaviorally thermoregulate …

Female multiple mating provides the opportunity for sexual selection to continue after
gamete release, generating strong selection on male reproductive traits. In particular, in …

Reproducing sharks must provide their offspring with an adequate supply of nutrients to
complete embryonic development. In oviparous (egg-laying) sharks, offspring develop …

Sexual dimorphisms are abundant in natural systems; however, their ecological and
evolutionary significance have largely been neglected with respect to Chondrichthyes. A …

In this study, multiple paternity (MP) was investigated in three commercially important shark
species, common smoothhound Mustelus mustelus, dusky shark Carcharhinus obscurus …
