The Dynamic Duo: Application of Complementary BRUVs and eDNA to Marine Fish Assemblages

Innovations in waterproofing cameras and DNA analysis have led marine scientists to apply these methods in unique ways in recent decades. Through the use of BRUVs and eDNA this article looks at fish assemblages in Jurien Bay Marine Park in Western Australia to compare these methods individually and combined. When BRUVs and eDNA were both […]

The Gulf of Mexico Triangle: Assessing Movements of Large Pelagic Fish Across Multiple National Boundaries

Pelagic predators or difficult to manage due to their vast migrations through through multiple countries jurisdictions and international waters. In order to effectively manage these species multinational agreeements are required. However, collecting movement data for species that travel long distances is difficult to collect. Here, researchers look at the movements between countries of 8 species […]

Hawksbills in hot water? Temperature and Precipitation Impacts on Hawksbill Sea Turtle Nests

Climate change is already having effects on sea turtles. All seven species of sea turtle are dependent on temperature for habitat selection and physiology. The impacts of temperature and moisture on hatchling development have real long-term impacts on marine turtle populations.

What’s next for Air Jaws? Research Priorities for The Great White Shark

Since the beginning of Discovery Channel’s Shark Week, viewers have been mesmerized by the great white shark (Carcharodon carcharias). The great white shark coverage outshines the rest with television specials like the Air Jaws series filling many of the week’s time slots. There are numerous unanswered questions about its ecology, physiology, and relationship with humans. To […]

Ecology of Fear: Current Implications of Orca Presence on Narwhal Behavior and Future Trends

The ecology of fear is a hypothesis that predators drive habitat use and behavior in prey species. In the Arctic, the orca drives behavioral changes in a variety of species including narwhals. Analyzing a narwhal population in a Fjord in Greenland researchers were able to look at how fear drives narwhal behavior. Article Breed, Greg […]

The Biological Big Bang: Testing the hypothesis that sperm whales use auditory bursts to stun prey and other proposed feeding strategies.

Article Fais, A., Johnson, M., Wilson, M., Soto, N. A., & Madsen, P. T. (2016). Sperm whale predator-prey interactions involve chasing and buzzing, but no acoustic stunning. Scientific reports, 6, 28562. Background Sperm whales (Physeter macrocephalus) are big. To put it in perspective, an adult or bull sperm whale is longer on average (52 ft.) […]

In the hot seat: Hot spots for pelagic shark movement reflect hot spots for commercial longline fisheries in the North Atlantic.

Check out the latest from Matt Larsen about shark habitat around the globe, and how these areas overlap with fishing hotspots! Matthew LarsenI am a second year master’s student at Coastal Carolina University in the Abel Lab. My interests focus on the ecology and life history of large marine megafauna with a central focus on […]

Jumbo Shrimp: The First Definitive Evidence of a Megalodon Nursery
