I like to argue that adaptation is the engine that drives Mother Nature. In biology, adaptation is broken down into three different aspects. The first of the tri-aspects is the natural selection matches an organism to their environment, which in turns enhances their evolutionary fitness. The second aspect of adaptation is a state reached by the population of the organism. And lastly, the adaptive trait plays a major role in the individual organism and is maintained through natural selection.
Wow, well if that first paragraph didn’t boar you to death, you may be as demented as I am. These are the kinds of things I think about when I come across something unique in nature. Recently while on a trip to photograph Polar Bears in the sub-arctic, I spotted an animal that embodies the concept of adaptation to its fullest, the Arctic Hare (Lepus arcticus).
I was moving across the tundra with all the arctic vegetation in its autumn blazing glory. Bright reds and vibrant yellows painted the landscape and turned everything into a vibrant visual scene. Large, smooth rocks, often covered in lichens, punctuated the landscape. This is the perfect habitat for an Arctic Hare.
So, it wasn’t hard to spot an Arctic Hare, mostly because of their adaptation. You see, Arctic Hares adapt to their environment, which means they turn white in winter to blend into the snowy landscape. However, since it was still autumn, no snow had fallen this season, so the white Arctic Hare sticks out like a white light on a dark background. During summer the Arctic Hares are a combination of gray and white which is an adaptation to blend into the rocky environment. To add to the intrigue, the Arctic Hares that live in the furthest northern regions stay white all year. This is an example of extreme adaption.
Arctic Hares are related to Jackrabbits and live in northern Canada and the coastal regions of the northern Canadian Islands, Greenland, Labrador and Newfoundland. They are a large hare, weighing between 7 to 11 pounds but can be up to 15 pounds. They are one of the largest hares (Lagomorphs) in the world. They are larger than most domestic cats and larger than some of the small domestic “teacup” dogs.
During autumn the Arctic Hares eat as much as they can, putting on upwards of 20 percent body fat. The body fat will help insulate them against the coming winter weather and also provide a reserve food storage for the times when major winter storms hit which often last for several days in a row.
