Environmental physiology is a scientific discipline that examines how organisms respond and adapt to their physical surroundings, such as changes in temperature, humidity, light levels, and altitude. This field explores the physiological mechanisms that allow organisms to survive and thrive in different environments, as well as the impact of environmental factors on various biological processes. Researchers in environmental physiology study a wide range of organisms, from plants and animals to microorganisms, in order to better understand how they interact with their environment and how these interactions influence their overall health and fitness. This research area has important implications for conservation biology, agriculture, and human health, as it helps us better understand how organisms cope with environmental challenges and how they may be affected by environmental changes in the future.
