Phenotypic plasticity refers to the ability of an organism to change its physical traits or characteristics in response to environmental factors. This can include factors such as temperature, availability of food or resources, and social interactions. Phenotypic plasticity allows organisms to adapt to changing environmental conditions and can help them survive and reproduce in different habitats. This research area explores how and why organisms exhibit phenotypic plasticity, and how it may influence their evolution and ecological interactions. Studies in this field often involve experiments to understand the mechanisms underlying phenotypic plasticity and its implications for the biology and ecology of organisms.
