How do animals adjust to environmental fluctuations caused by climate change?

Seasonal and weather-related changes in environmental conditions are normal in almost all parts of the world. They affect the availability of food and the energy expenditure of animals in a largely predictable way. However, we are currently experiencing a significant increase in annual temperatures and, in particular, in the frequency of extreme weather events. It is therefore important to understand how the body's internal processes respond to environmental changes and mediate adaptations of animals to be able to assess whether species will be able to cope or become extinct.
