Researchers from Canada and the US reveal traits that make fish prey tasty to tuna

Tridge summary

A global database has been established by an international science collaboration to aid researchers in understanding the impact of climate change on ocean predators like albacore tuna. The database, which categorizes over 30 traits of potential prey, aims to predict the location and timing of the most desirable prey as climate changes. Meanwhile, marine heatwaves are causing species to appear hundreds of miles from their known habitats and some to lose entire habitats, as they can only endure certain ranges in temperature, acidity, and other stressors. These findings are the result of research conducted by Stanford University's Hopkins Marine Science Center and the University of Alberta.

A cross-border science collaboration has yielded a global database that will help researchers understand how climate change is affecting ocean predators like the albacore tuna—which also happens to be an important food source for people around the world."Climate change is shifting where species can live, and the pace of change is most intense in the ocean," says Stephanie Green, associate professor in the Department of Biological Sciences and Canada Research Chair in Aquatic Global Change Ecology and Conservation."Our big questions are where will marine species go, and what will it mean for communities that rely on the fisheries they support?"To tackle these questions, researchers at the University of Alberta are collaborating with colleagues in the United States to discover how top predators will respond to climate extremes and changing prey over the coming decades.Wind and currents in the Pacific Ocean make the west coast of Canada and the United States an attractive feeding ...
