Organized grouping mediates the environmental interactions of social squids
Abstract/Contents
- Abstract
- A surge of recent research suggests that current and future shifts in marine species' distributions are ultimately driven by physiological responses to environmental variation. These observations and predictions are important because changes in species' distributions cause ecological change through community reorganization. However, they do not necessarily capture the full effects of behavioral adaptations on species' ecologies. Behaviors mediate the response of an organism's physiological processes to environmental variation, and can profoundly affect individual fitness, and thus population demography and community dynamics, under environmental variability. One of the most conspicuous and taxonomically widespread behaviors of animal life in the ocean is social behavior, or aggregation behavior related to inter-individual cohesion among conspecifics. Social interactions can buffer physiological responses to stressful conditions, shape behavioral patterns of individuals, and drive individual decision-making, with ecological and evolutionary consequences. While these impacts are becoming increasingly apparent in other systems, to date very few investigations explicitly consider the mechanisms and physiological effects of social behavior in the ocean. Squid, a predominantly predatory clade of highly motile molluscs, are a particularly compelling group of marine animals with which to develop such understanding. Many squids are social, occur across a range of environmental conditions, possess activity-limiting physiological constraints, visually communicate with complex pigmentation patterning, and demonstrate considerable ecological and life history flexibility. In this dissertation, I examine the patterns, mechanisms, and physiological effects of social behavior in open ocean squids, and how physiological sensitivities to environmental variability in squids can lead to new ecological interactions of potential consequence. Joining an emerging body of research, my dissertation work shows how social behaviors that confer emergent benefits are adapted to environmental gradients in the ocean. It also highlights the importance of social behavior in understanding habitat selection and the corresponding ecological changes in the ocean. As empirical and theoretical research continues to explore how social behavior shapes such ecological patterns, the understanding we develop will facilitate more sustainable harvest, more effective conservation, and more accurate predications under global change.
