In fact, such habitats have been considered early warning systems for climate change impacts. Their low depth means that they have a lower thermal inertia than open-ocean waters, and that their thermal regime is affected by both oceanographic and atmospheric conditions. Shallow coastal waters are among the habitats where the impacts of climate warming will be apparent more rapidly, making these areas useful natural laboratories, not only for the study of community dynamics as they traditionally have been, but also for climate change research. These changes should occur at rapid rates exposing animals to conditions they have not experienced in their evolutionary history. Global warming has the potential to dramatically change environments worldwide. They are likely to increase local extinction risk, thus understanding where they may occur and what species will be affected is important for conservation biology. This way, tropical coastal organisms seem to be, not only more vulnerable to climate warming per se, but also to an increase in the ecological trap effect of tide pools.Įcological traps, which happen when environmental changes cause maladaptive habitat selection, have been identified for many species, in diverse ecosystems, most of them terrestrial. Tropical species have higher thermal limits than temperate species, but lower acclimation response, that does not allow them to survive the maximum habitat temperature of tropical tide pools. Tide pools are not ecological traps in temperate zones. Tropical tide pools were found to be ecological traps for an important number of common coastal species, given that they can attain temperatures higher than the upper thermal limits of most of those species. The upper thermal limits of the organisms were compared to the temperatures attained by tide pool waters to investigate if 1) tide pools could be considered ecological traps and 2) if the increase in upper thermal limits elicited by the acclimation period could make the organisms less vulnerable to this threat. Their upper thermal limits were estimated again, after this acclimation period, to calculate each species’ acclimation response. They were maintained for 10 days at their mean summer sea surface temperature +3☌, mimicking a heat-wave.

Common tide pool species (46 species in total) were collected at a tropical and a temperate area and their upper thermal limits estimated. If organisms undergo acclimatization prior to being trapped in tide pools, their survival chances may increase.

However, heat waves can also lead to acclimatization.

Heat-waves are predicted to increase in intensity, duration and frequency, making it relevant to investigate the role of tide pools as traps for coastal organisms. That means that tide pools are potential ecological traps for coastal organisms, which happen when environmental changes cause maladaptive habitat selection. Mortality of fish has been reported in tide pools during warm days.
