A perceptual trap is an ecological scenario in which environmental change, typically anthropogenic, leads an organism to avoid an otherwise high-quality habitat. The concept is related to that of an ecological trap, in which environmental change causes preference towards a low-quality habitat.
History
In a 2004 article discussing source–sink dynamics, James Battin did not distinguish between high-quality habitats that are preferred or avoided, labelling both "sources". The latter scenario, in which a high-quality habitat is avoided, was first recognised as an important phenomenon in 2007 by Gilroy and Sutherland, who described them as "undervalued resources". The term "perceptual trap" was first proposed by Michael Patten and Jeffrey Kelly in a 2010 article. Hans Van Dyck argues that the term is misleading because perception is also a major component in other cases of trapping.
Description
Animals use discrete environmental cues to select habitat.Kristan, W. B. (2003) "The role of habitat selection behavior in population dynamics: source–sink systems and ecological traps," Oikos, 103: 457–468 A perceptual trap occurs if change in an environmental cue leads an organism to avoid a high-quality habitat. It differs, therefore, from simple habitat avoidance, which may be a correct decision given the habitat's quality. The concept of a perceptual trap is related to that of an ecological trap, in which environmental change causes preference towards a low-quality habitat. There is expected to be strong natural selection against ecological traps, but not necessarily against perceptual traps, as Allee effects may restrict a population’s ability to establish itself.
