Research finds that animals are “deformed” in response to climate warming

“Many times, when mainstream media discuss climate change, people are asking’can humans overcome this problem’ or’what technology can solve this problem’. Now it is It is time for us to realize that animals must adapt to these changes, but the time scale for this to happen is much shorter than most of the evolutionary time,” Ryding said. “The climate change we have caused puts a lot of pressure on them. Although some species will adapt, others will not.”

Ryding pointed out that climate change is a complex and multifaceted phenomenon. , Has been happening gradually, so it is difficult to point out only one reason for the deformation. But these changes have always occurred in a wide range of geographic areas and between different species, so apart from climate change, there is nothing in common.

The most found in birds The strong deformation phenomenon. Observations of several Australian parrots show that since 1871, the size of their beaks has increased by an average of 4%-10%, and this is positively correlated with the annual summer temperature. North American dark-eyed bunting, a small songbird. In cold environments, the increase in beak size is associated with short-term extreme temperatures. There are also reports of changes in mammalian species. Researchers have reported an increase in the length of the tail of the wood mouse, as well as an increase in the size of the tail and legs of the skin shrew.

Ryding said: “So far , The increase in the size of the appendages we see is quite small, less than 10%, so these changes are unlikely to be noticed immediately. However, protruding appendages, such as ears, are expected to increase, so we may A live-action version of Dumbo will appear in the near future.”

Next, Ryding intends to personally investigate the deformation of Australian birds through 3D scanning of museum bird specimens from the past 100 years. This will allow her team to better understand which birds have changed the size of their appendages due to climate change, and why. “Deformation does not mean that animals are responding to climate change, everything is’good’.” It just means that they are evolving to survive in it-but we are not sure what the other ecological consequences of these changes are, or indeed all species Both can change and survive. “
