It's been a brutally hot summer in North Dakota and I got to thinking about zoo animals here. The Dakota Zoo for example, has several species native to high mountains such as snow leopards, Dall's sheep, bighorn sheep, mountain goats, and I believe Transcaspian urial. They just have simple shelters for winter, and while they have shade, they don't have what appears to be much else for cooling. Does the heat just not bother species like that very much? Are there zoos in year round warm climates that keep species like this in similar conditions? I know San Diego has caribou and from what I understand they do fine. Is it the same with the species I mentioned?
