Proceedings of the National Academy of Sciences, 118(30), e2100707117. Surviving winter on the Qinghai-Tibetan Plateau: Pikas suppress energy demands and exploit yak feces to survive winter. B., Wang, X., Zhang, L., Redman, P., Wang, L., Tang, G., Li, Y., Cui, J., Thomson, P. A cute little Pika - a common high altitude Himalayan rodent which resembles a rat but is known as a Mouse-hare and has features of both mice and hares. Low-elevation pika populations, however, are at high risk of climate change, particularly local warming and decreased precipitation ( see also Causes of Global Warming ). E., Hambly, C., Togo, J., Liu, X., Piertney, S. The American pika lives primarily at elevations between 8,000 and 13,000 feet, though it may be found at significantly lower elevations, including a little above sea level. They prefer cool and moist environments and thrive at. There are many different types of animals that look like rabbits. The main difference between the two animals is that the vizcacha is much larger, measuring up to 3 feet in length. It has long ears, big eyes, and a fluffy tail, just like a rabbit. R., Chi, Q., Ołdakowski, Ł., Fu, H., Fletcher, Q. One of my favorite little rodent like mammals, the American Pika, lives in the high alpine ecosystem. The vizcacha is a rodent that is native to South America. Now we know how far our furry friends are willing to go to make it! Results? During winter, pikas save up to THIRTY percent of their energy – by moving less to reduce their body temperature! This way, they only make special trips into the cold!īut what do pikas find to eat in their frozen habitat? Cameras revealed their shocking diet - YAK POOP-SICLES! Talk about “Fear Factor!” the later claim is clearly contravened by Smith and Foggin Lai and Smith Delibes-Mateos et al. They monitored the critters’ body temperature and metabolic rate to see how they weather the cold. pikas are lagomorphs, not rodents also dig and destroy vegetation causing many serious problems such as soil erosion, and reductions in livestock carrying capacity and ecosystem diversity n.b. But not the pika! What’s their secret?Įnter John Speakman from the Chinese Academy of Sciences and team! They filmed pikas living their best rodent lives for THIRTEEN years. ![]() ![]() Other small rodents from freezing places either get outta town or hibernate. BUT plateau life is no small feat! Temperatures can reach negative twenty degrees fahrenheit, and food becomes HARD to find. In the Qinghai-Tibetan plateau of Southeast Asia lives the plateau pika – a little rodent the length of a butter knife. They feed on all sorts of plant material. This is Sandra Tsing Loh with the Loh Down on Science. Pikas are diurnal and are active early and late in the day during hot weather.
