To address these questions, we employ a combination of tried and innovative techniques in wildlife telemetry (archival, acoustic, and accelerometery) and molecular genetics. It allows us to investigate stock structure, behavior, and short and long term movements within a variety of habitats (MPAs, open ocean, reef systems, etc) on a daily, seasonal and ontogenetic time scale.
We look to define the regions of the ocean that are important to these species; determine the oceanographic conditions that define their habitat; learn of their movement patterns within these areas; and investigate potential ecological implications of their endothermic physiology (if pertinent). Most of these animals are commercially important fish for international fisheries and effective management of existing biodiversity requires an understanding of their biology and population structure.
Tracking megafauna within BIOT, a Marine Protected Area that is larger than the US state of California, is a challenge. Thankfully with new technology, we are able to figuratively “peel back the ocean” to get a snapshot into where these animals spend the majority of their time...defining hot spots as well as migration corridors in order to inform management and enforcement.
