Abstract
ABSTRACTGreen abalone (Haliotis fulgens) experienced severe biomass losses and massive mortality due to short-term marine climatic extremes. We studied green abalone behavior and energy expenditure in response to environmental stress. Acclimatized juveniles were subjected to hyperthermia (26°C), hypoxia (1.0 mg O2 L-1), the combination of both, and control conditions (18°C and oxygen saturation) using an automated system. The movement parameters of organisms were recorded by labeling and filming them, and the respiration rate was measured in hermetic chambers. There were differences in gross and net distance and velocity between the control and the combined stressors. Respiration was raised by hyperthermia, lowered by hypoxia, and further reduced by the combined stressors. All abalone that left the shelter during the night returned by daylight, while hypoxia and hyperthermia reduced this number. Research on environmental stress and movement strategies could lead to a more objective stress proxy.KEYWORDS: Behaviorclimate changebenthic ecosystemsecophysiology AcknowledgmentsThis work was supported by the Consejo Nacional de Ciencia y Tecnología (Mexico) under grant CB 287237.

期刊介绍:
Marine and Freshwater Behaviour and Physiology is devoted to the publication of papers covering field and laboratory research into all aspects of the behaviour and physiology of all marine and freshwater animals within the contexts of ecology, evolution and conservation.
As the living resources of the world’s oceans, rivers and lakes are attracting increasing attention as food sources for humans and for their role in global ecology, the journal will also publish the results of research in the areas of fisheries biology and technology where the behaviour and physiology described have clear links to the contexts mentioned above.
The journal will accept for publication Research Articles, Reviews, Rapid Communications and Technical Notes (see Instructions for authors for details). In addition, Editorials, Opinions and Book Reviews (invited and suggested) will also occasionally be published. Suggestions to the Editor-In-Chief for Special Issues are encouraged and will be considered on an ad hoc basis.
With the goal of supporting early career researchers, the journal particularly invites submissions from graduate students and post-doctoral researchers. In addition to recognising the time constraints and logistical limitations their research often faces, and their particular need for a prompt review process, accepted articles by such researchers will be given prominence within the journal (see Instructions for authors for details).
