The University of Zurich's 40-year dolphin research in Shark Bay, Australia, highlights the impact of climate change on these marine mammals. Researchers use DNA sampling and environmental DNA (e-DNA) analysis to study dolphin behavior, genetics, and habitat.
Key findings include the dolphins' tool use, such as using sponges to hunt in deeper, less affected areas during marine heatwaves. The 2011 heatwave, which decimated seagrass beds, led to increased dolphin mortality and reduced birth rates.
Scientists are mapping dolphin habitats and prey availability to understand how climate change affects them. Research shows that tool-using dolphins are more resilient to environmental changes. The ongoing research aims to address the future of dolphins in a rapidly changing environment.
