A new UBC study shows that climate warming can potentially make bacterial and fungal infections deadlier for cold-blooded animals like corals, insects, and fish, raising questions about the broader risks warming temperatures pose to ecosystems and biodiversity -- and potentially humans.

Using statistical models, the researchers found that cold-blooded animals with bacterial infections were more likely to die when exposed to higher temperatures compared to their usual environmental conditions.

"These findings suggest that climate warming may pose a greater risk to cold-blooded animals, an important part of the ecosystem," said Dr. Li.

In the early 20th century, dinosaurs were considered slow-moving, "cold-blooded" animals like modern-day reptiles, relying on heat from the sun to regulate their temperature.

Cold-blooded animals, including reptiles like snakes and lizards, depend on outside sources to control their temperature: For example, basking in the sun to warm up.
