Because the climate is so harsh, cooperation increases the survival rate of the Olympic marmots.

Their social behavior is so different from Eastern marmots because of the climate where they live?

The Olympic marmots inhabit meadows high in the Olympic Mountains where the weather conditions are much harsher.

Roughly six weeks after birth, Eastern marmots are just old enough to take their chances of surviving in the temperate environment.

那时，地上没有冰雪覆盖，草木也没有结霜，土拔鼠喜欢吃的植物嫩芽和花蕾正开始生长。

Even though they spend the significant portion of the year hibernating, according to this case study, marmots are still considered excellent subjects for animal behavioral studies.

The marmots in question live in the Grande sassiere Nature Reserve in the French Alps.

Thanks to warming temperatures in Colorado, the marmots have been getting up earlier from hibernation each year, giving them more time to feed.

由于科罗拉多州不断上升的气温，那里的旱獭每年从冬眠中醒来的时间都会比以往早些，这样它们有了更多的进食时间。

Marmots didn't have that limitation though, he says, "so the idea that there may be something systematic here between species is extremely interesting."

不过土拨鼠们并没有那样的界限，他说，“因此有人猜测在物种之间可能存在着系统化的现象，这太有意思了。”

Marmots don't have Facebook yet, but animals living among clusters of burrows in Colorado do interact enough for observers to plot networks with each marmot as a node.

土拨鼠们还没用上Facebook，不过在科罗拉多州，群居于洞穴中的动物互动甚为频繁，足够使观察者们通过把每只土拨鼠作为一个结点，来划分其社会网络。
