Effects of salinity as a stressor to aquatic invertebrates

Effects of salinity as a stressor to aquatic invertebrates
Effects of salinity as a stressor to aquatic invertebrates
This chapter provides an overview of the cellular impacts of changes in the osmotic potential of the extracellular environment and how cells and, indeed, aquatic invertebrates regulate these impacts over acute and chronic time scales. Central to this osmotic control through cell volume regulation and cell ionic homeostasis is the requirement for energy, and this underpins many of the negative impacts to organism physiology, biochemistry, growth, and development which are subsequently considered in this chapter. Impacts on organisms from salinity perturbation can be either direct or indirect, and both are considered. Throughout this chapter, laboratory or experimental examples to support basic principles are described, and the challenge associated with developing these ideas within a complex ‘Real World’ of multiple and simultaneously acting stressors is considered.

Abstract

This chapter provides an overview of the cellular impacts of changes in the osmotic potential of the extracellular environment and how cells and, indeed, aquatic invertebrates regulate these impacts over acute and chronic time scales. Central to this osmotic control through cell volume regulation and cell ionic homeostasis is the requirement for energy, and this underpins many of the negative impacts to organism physiology, biochemistry, growth, and development which are subsequently considered in this chapter. Impacts on organisms from salinity perturbation can be either direct or indirect, and both are considered. Throughout this chapter, laboratory or experimental examples to support basic principles are described, and the challenge associated with developing these ideas within a complex ‘Real World’ of multiple and simultaneously acting stressors is considered.
