This suggests that Neanderthal faces were not shaped to deal with extreme cold, says Rae's team. File previews. Woolly mammoths, unlike the African and Asian elephants, moved from a tropical to an Arctic environment, which facilitated possible physiological specializations to cold climates. The shape of the tree helps the tree to shed snow. In free populations of house mice cold lowers fertility and may prevent breeding. The shifts for some warm-blooded animals are occurring over a far shorter time period than would usually happen. Just like humans, researchers say animals also have to adapt to climate change. ppt, 3.07 MB. Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. Adequate public health responses to temperature related effects of climate change require a sound risk management process, informed by the use and synthesis of relevant evidence. Examples of temperature adaptation. Extreme cold favours short, round persons with short arms and legs, flat faces with fat pads over the sinuses, narrow noses, and a heavier-than-average layer of body fat.
