They may need to adapt to new environmental conditions, such as changes in water temperature and availability, in order to survive. shuerta47 https://padlet.com/shuerta47/fcf4xqs5sw1vesmc/wish/2590461258 2023-05-15 01:32:37 UTC https://padlet.com/shuerta47/fcf4xqs5sw1vesmc/wish/2590461258 Adaptations for survival:Possible adaptations for the American alligator to survive in the face of climate change include changes in behavior, such as shifting their nesting habits to adapt to changes in water levels, and physiological changes, such as increasing their tolerance to higher water temperatures. Natural selection may play a role in selecting for individuals with these adaptations, which will increase the likelihood of their survival and success in the face of changing environmental conditions. shuerta47 https://padlet.com/shuerta47/fcf4xqs5sw1vesmc/wish/2590461423 2023-05-15 01:32:46 UTC https://padlet.com/shuerta47/fcf4xqs5sw1vesmc/wish/2590461423
