▪ Abstract The movement of individuals defines a spatial neighborhood that can help
determine marine management strategies. Here, I briefly review four fields of marine biology …

Biology of Sharks and Their Relatives is an award-winning and groundbreaking exploration

In The Genesis of Animal Play, Gordon Burghardt examines the origins and evolution of play
in humans and animals. He asks what play might mean in our understanding of evolution …

Long‐distance migration has evolved in many organisms moving through different media
and using various modes of locomotion and transport. Migration continues to evolve or …

The study of long-distance migration provides insights into the habits and performance of
organisms at the limit of their physical abilities. The Arctic tern Sterna paradisaea is the …

Electronic tracking tags have revolutionized our understanding of broad-scale movements
and habitat use of highly mobile marine animals, but a large gap in our knowledge still …

The large-scale spatial dynamics and population structure of marine top predators are
poorly known. We present electronic tag and photographic identification data showing a …

Advances in electronic tagging and genetic research are making it possible to discern
population structure for pelagic marine predators once thought to be panmictic. However …

Global declines of shark populations are of concern because of their largely assumed role
as moderators of ecosystem function. Without long-term data on movement patterns for …

Abstract The European eel (Anguilla anguilla Linnaeus 1758) is a species typical for waters
of Western Europe. Thanks to early expeditions on the Atlantic Ocean by the Danish …
