The term used to describe adaptations developed in response to environmental stressors is “adaptive traits.” These traits enhance an organism's ability to survive and reproduce in specific environments, often through gradual processes of natural selection. Adaptive traits can include physiological changes, behavioral modifications, or structural adjustments that improve resilience to conditions such as temperature extremes, predation, or resource scarcity. Over time, populations exhibiting these traits may become better suited to their environments, leading to increased survival rates and potential speciation, thereby contributing to biodiversity.
