A comprehensive meta-study has revealed critical insights into how animals are adapting to the challenges posed by climate change.Conducted by an international team of scientists, the study analyzed over 200 scientific studies focusing on 73 different animal species, aiming to understand the relationship between climate change and various biological traits such as phenology, morphology, and population dynamics.

phys.orgThe findings, published in the journal Nature Communications, indicate that climate change significantly influences seasonal developmental processes, which in turn affect population numbers.The researchers found that phenological traits—seasonal developmental phenomena—are particularly sensitive to temperature changes, allowing many species to cope with the shifting climate.

phys.orgThe study categorized adaptations into three main types: behavioral, physiological, and morphological changes.For instance, shifts in breeding times and other seasonal behaviors were observed, with many species adjusting their reproductive cycles to align with optimal environmental conditions.
