Heat stress is a research area that focuses on the physiological and biochemical responses of organisms to elevated temperatures. This can occur in a variety of environments, including both natural ecosystems and agricultural settings. Heat stress can have negative impacts on organisms, causing issues such as reduced growth and reproduction, increased susceptibility to diseases, and even death in extreme cases. Researchers in this area aim to understand the mechanisms by which organisms respond to heat stress, in order to develop strategies to mitigate its effects and improve resilience in the face of increasing global temperatures.
