Over the last decade, numerous studies have investigated the role of oxygen in setting
thermal tolerance in aquatic animals, and there has been particular focus on arthropods.
Arthropods comprise one of the most species-rich taxonomic groups on Earth, and display
great diversity in the modes of ventilation, circulation, blood oxygen transport, with
representatives living both in water (mainly crustaceans) and on land (mainly insects). The
oxygen and capacity limitation of thermal tolerance (OCLTT) hypothesis proposes that the …
