And herein lies the premise: if drivers are moving slowly enough, they will have time to avoid hitting large animals, such as deer and pronghorn, on the road.

Animals like elk in North America and vicunas in the Andes also share those same priorities, and what new research shows is how they respond to those fears depends mostly on what’s trying to eat them.

Many complex nonhuman animal societies are concentrated in biological hotspots like the Serengeti.Humans are not knowledgeable or sophisticated enough to depict every individual creature on our maps, but surely we can display the animal habitats of which we are aware.

Kristin Laidre, an animal ecologist at the University of Washington and a coauthor, says the melting summer sea ice is causing trouble for big mammals: polar bears, walruses, and seals.

By combining DNA sequence data with gene expression profiles from deer, goats, and sheep, the consortium scientists identified a handful of genes that work together to keep such species cancer-free, even as they grow pounds of new tissue on their heads each year.

“We injected macaques with extremely high levels of CWD-infected deer and elk brains without any evidence of CWD,” says Race, who cautions that it only takes one mismatch in an amino acid sequence to create a species barrier.
