Of the 356 species of turtles worldwide, approximately 61% are threatened or already extinct. Turtles among most major groups vertebrates, in general, more so than birds, mammals, fishes even much besieged amphibians. Reasons for dire situation worldwide include familiar list impacts to other including habitat destruction, unsustainable overexploitation pets and food, climate change (many have environmental sex determination). Two notable characteristics pre-Anthropocene were their massive population sizes correspondingly high biomasses, latter highest values (over 855 kilograms per hectare) ever reported animals. As a result numerical dominance, played important roles as significant bioturbators soils, infaunal miners sea floors, dispersers germination enhancers seeds, nutrient cyclers, consumers. The collapse turtle populations on global scale has greatly diminished ecological roles.

Abiotic conditions (e.g., temperature and pH) fluctuate through time in most marine environments, sometimes passing intensity thresholds that induce physiological stress. Depending on habitat season, the peak of different abiotic stressors can occur or out phase with one another. Thus, some organisms are exposed to multiple simultaneously, whereas others experience them sequentially. Understanding these physicochemical dynamics is critical because how respond depends magnitude relative timing each stressor. Here, we first discuss broad patterns covariation between systems at various temporal scales. We then describe will influence responses multi-stressor exposures. Finally, summarize effects currently assessed. find experiments have rarely incorporated naturalistic variation into their designs, emphasize importance doing so make ecologically relevant inferences about global change.
