Physiological traits refer to the physical and functional characteristics of an organism that are related to its biological processes and functions. These traits can include aspects such as metabolism, growth rate, immune function, reproduction, and response to environmental stressors. Studying physiological traits can provide valuable insights into the health, behavior, and evolutionary adaptations of organisms, as well as their ability to survive and thrive in their environments. Research in this area often involves experimental studies, field observations, and genetic analyses to investigate the mechanisms underlying physiological traits and their role in biological processes.
