Ecological traps, which occur when animals mistakenly prefer habitats where their
fitness is lower than in other available habitats following rapid environmental
change, have important conservation and management implications. Empirical
research has focused largely on assessing the behavioural effects of traps, by
studying a small number of geographically close habitat patches. Traps, however,
have also been defined in terms of their population-level effects (i.e. as
preferred habitats of sufficiently low quality to cause population declines), and
this is the scale most relevant for management. We systematically review the
ecological traps literature to (i) describe the geographical and taxonomic
distribution of efforts to study traps, (ii) examine how different traps vary in
the strength of their effects on preference and fitness, (iii) evaluate the
robustness of methods being used to identify traps, and (iv) determine whether
the information required to assess the population-level consequences of traps has
been considered. We use our results to discuss key knowledge gaps, propose
improved methods to study traps, and highlight fruitful avenues for future
research.
