These questions persist despite the fact that development in marine invertebrates has been ... tantalizing questions remain concerning origins and ecologies of larvae. This book brings together a wide-ranging collection of chapters on marine invertebrate larvae which overall suggest that there are likely

Sex, size and isotopes: cryptic trophic ecology of an apex predator, the white shark Carcharodon carcharias

Demographic differences in resource use are key components of population and species ecology across the animal kingdom. White sharks (Carcharodon carcharias) are migratory, apex predators, which have ... range. Understanding their ecology is key to ensuring that management strategies are effective. Here, we carry out the first stable isotope analyses of free-swimming white sharks in South Africa. Biopsies
