Regarding this slithery video, you’re right! It is reproduction but it’s also for hibernation and body heat efficiency. The garter snake is my home state, Massachusetts, “State Reptile”! They also converge in large numbers in New England to den in the winter, just not the thousands like in Canada. So weird and awesome!
PS, Check out this article on how climate change will impact American rattle snake’s habitat. Basically, it seems rattlers are too slow to adapt to rapid climate changes and may be wiped out in some areas because it has no suitable habitat to migrate to…
The ranges of species will have to change dramatically as a result of climate change between now and 2100 because the climate will change more than 100 times faster than the rate at which species can adapt, according to a newly published study by Indiana University researchers.
The study, which focuses on North American rattlesnakes, finds that the rate of future change in suitable habitat will be two to three orders of magnitude greater than the average change over the past 300 millennia, a time that included three major glacial cycles and significant variation in climate and temperature.
"We find that, over the next 90 years, at best these species’ ranges will change more than 100 times faster than they have during the past 320,000 years," said Michelle Lawing, lead author of the paper and a doctoral candidate in geological sciences and biology at IU Bloomington. "This rate of change is unlike anything these species have experienced, probably since their formation."
