Electronic Tagging and Tracking Marine Animals Supports Conservation

Understanding and predicting animal movement is important as it is central to establishing effective management and conservation strategies [1]. Until relatively recently, studying the movements and behaviors of highly migratory marine species (turtles, sharks, whales, penguins, seals and billfish) have been ...
