  The behavior of many animals, including humans, are influenced by the cycle of the moon. For example, many fishes time their reproductive events with the full moon. Together with Chris & Monique Fallows, I have been fortunate enough to study predator-prey interactions between great white sharks and cape fur seals at Seal Island in…

In the past I have blogged about how the use of electronic tagging and tracking can support the conservation of marine animals. I have also addressed some misconceptions about shark tagging studies and discussed the value of such research for conservation. Building off these topics, I would like to share the results of two recently…

New research on tropical coral reef ecosystems showed that releasing larvae more often is beneficial for a species’ network. The study on reproductive strategies is critical to assess the conservation of coral reef ecosystems worldwide. Researchers from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science used a computer model developed by…

A new research study on marine snails uncovered the first cells in the nervous system to fail during aging. The University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science researchers’ findings are important to better understanding the underlying mechanisms of age-related memory loss in humans. Scientists performed tail reflex experiments on the hatchery-reared…

An international team, led by researchers has developed a new, timelier method to identify harmful bacteria levels on recreational beaches. The new model provides beach managers with a better prediction tool to identify when closures are required to protect beachgoers from harmful contaminates in the water. “The development of this new model has allowed us,…

In honor of Shark Week, for the next few days I am going to be posting some cool facts and photos of the sharks I have had the pleasure of swimming with. Check out the Shortfin Mako Shark (Isurus oxyrinchus), one of the fastest fish in the ocean.   Shortfin Mako facts at a glance…

For several years now, I have been using electronic tagging to study the movements and behaviors of sharks. You can find out more about this research HERE and watch a video HERE.   I previously wrote about the state of electronic tagging and tracking marine animals. However, recently there have been a lot of myths,…

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 challenging due to the logistical and technological constraints of working in aquatic environments. However,…

Shark Declines: Fuel for a Decade of Conservation Effort by Austin J. Gallagher & Neil Hammerschlag     Scientists have been studying the population status of sharks for years and while the vulnerability, threatened status and biological importance of sharks has long-been well-recognized and documented by the research community (1), ten years ago, shark conservation…
