Comparative foraging behaviour in eared seals
This project focuses on understanding how sea lions, which are top predators in the ocean, behave and adapt to different environments.
I am studying five species of sea lions —Galápagos, California, southern, Australian, and New Zealand sea lions— spanning diverse ecosystems, environmental conditions, and anthropogenic disturbances. The goal is to figure out why these animals behave differently and how their behavior affects the health of their populations. The study has three main parts.
First, I am looking at detailed data about where and how female sea lions dive and move around. This will help me understand the unique behaviors of different sea lion groups.
Second, I want to know how the environment, like the type of ocean and competition between sea lions, influences their behavior. By studying these factors, I hope to uncover why sea lions in one area may act differently from those in another.
Lastly, I am examining how the way sea lions search for food, along with human activities like fishing, impacts the overall number of sea lions. This information can help us better protect these animals and maintain a healthy balance in ocean ecosystems.
This global research effort brings together scientists from different parts of the world to compare sea lion behaviors. The ultimate aim is to provide a clearer picture of how these fascinating animals adapt to their surroundings and what it means for their survival.
