Habitat-generalist

A habitat-generalist is a species that can thrive in a wide variety of environmental conditions and habitats. Unlike specialists, which are adapted to specific and often narrow niches, generalists possess a broader tolerance for variations in factors like temperature, humidity, food sources, and shelter availability. This adaptability often allows generalists to colonize and persist in diverse ecosystems, and to withstand environmental changes more effectively than specialists. Their success is linked to flexible behaviors, dietary versatility, and physiological resilience. Consequently, they may often be found in both disturbed and undisturbed environments.
