In shark populations, variation in sexual size dimorphism (SSD) appears to be related with
the reproductive mode. Here, we aimed to investigate the reproductive biology of the …

While sexual size dimorphism (SSD) is abundant in nature, there is huge variation in both
the intensity and direction of SSD. SSD results from a combination of sexual selection for …

Sharks, which maintain the role of top predator in aquatic ecosystems, have a reproductive
system and life history traits that are quite different from those of most teleosts, including …

Segregation of the sexes within a species is a widespread behavioural phenomenon in both
terrestrial and aquatic animals. In the marine realm, sexual segregation is exhibited by many …

Female scalloped hammerhead sharks move offshore at a smaller size than do males to
form schools composed primarily of intermediate size female sharks. This movement results …

Deep-water sharks exhibit species-specific reproductive strategies, which include
segregation by sex, size and reproductive stage. However, due to the wide spatial …

Large pelagic sharks are declining in abundance in many oceans owing to fisheries
exploitation. What is not known however is whether within-species geographical …

Most demographic models explicitly track the dynamics of a single sex. However, single-sex
models may lead to rather poor results when vital rates and other demographic parameters …

The cosmopolitan lamniform shark Carcharias taurus (commonly known as the ragged-
tooth, grey nurse or sand tiger shark) is threatened by overexploitation in parts of its range …

Restricted gene flow and reproductive philopatry are increasingly being described in marine
predators such as sharks. However, observing shark reproductive behaviour in situ is …
