The big short amazon5/31/2023 Jirinec said he is not sure what the long term effects of the trend will be on bird populations. The connection between longer wingspans and a warming climate was less easily explained, Jirinec said, but he speculated that it could be to allow the birds to fly more efficiently by compensating for their shrinking body size. “If you’re small in hot climates, you can offload heat better and that’ll lead to the expectation that with a warming climate, you would see decreasing body sizes.” You don’t lose heat as much,” Jirinec said. “If you’re in a cold environment, it’s beneficial to be bigger because you have a lower surface-to-volume ratio. The connection between body size and a warmer climate fits with the idea that within a widely distributed species, individuals closer to the equator will have a smaller body size than those closer to the poles, said Vitek Jirinec, lead author and bird ecologist at Louisiana State University.
