生态陷阱

生态陷阱（）是环境的快速变化导致生物反而偏好在劣质棲息地定居的情景。这一概念的基础是，主动选择栖息地的生物依靠环境线索来识别高质量栖息地。若栖息地质量或线索发生改变，令两二者不再相符，则生物可能会被引导至质量较差的栖息地。.

Source–sink dynamics

Source–sink dynamics is a theoretical model used by ecologists to describe how variation in habitat quality may affect the population growth or decline of organisms.

Ecological trap

Ecological traps are scenarios in which rapid environmental change leads organisms to prefer to settle in poor-quality habitats.
