Marmot Diversity And Groundhog Misconception
- Marmots are a diverse clade of large ground squirrels with about 15 species across the Northern Hemisphere.
- Groundhogs (woodchucks) are one species of marmot and are not representative of all marmot social systems.
Marmots Are Extreme Hibernators
- Marmots are the largest true hibernators and actively suppress metabolism and body temperature during torpor.
- Yellow-bellied marmots can weigh ~5 kg and burn about one gram of fat per day in deep torpor.
Two Types Of Fat For Hibernation
- Hibernators must accumulate two types of fat: fuel to burn and insulating fat for warmth.
- Marmots target specific plant fatty acids to build those differing fat stores before hibernation.
