Trepanier added that understanding the human and ecological dimensions is just as important as the physics because humans respond differently to risk.

This environmental shift, the authors suggest, caused widespread ecological and economic challenges.

By analyzing ecological and geographic patterns, researchers found that dinosaur populations in western North America were divided into separate "bioprovinces" shaped primarily by regional temperature differences rather than by mountains or rivers.

Fossil evidence also revealed that these warm-adapted hippos lived alongside cold-climate animals such as mammoths and woolly rhinoceroses -- an unusual ecological mix that highlights the complexity of Ice Age environments.

“Wolves are here in California and that is an amazing ecological return. Yet, their reemergence is a significant, disruptive change for rural communities.”
