PHYSIOLOGICAL PERSPECTIVES IN FRESHWATER SALINIZATION RESEARCH

The changing salinity of freshwater ecosystems has emerged as an ecological issue throughout the world because biodiversity losses are often associated with these changes. Regulatory entities have been slow to respond to this issue, in part, because our scientific understanding of how salinity affects biota is relatively poor. At the physiological level, it remains unclear whether salinity effects arise from toxic concentrations of individual ions, interactions among ions, or the overall salinity of all ions in solution. Further, we don’t yet understand if toxicity arises from a dysregulation of ion content in body fluids, or whether the energetic costs of regulating internal ionic composition is more relevant to understanding salinity effects. In this talk, I will synthesize recent research that highlights the potential importance of the energetics of osmoregulation in aquatic insects. I will further discuss how an interactive blend of lab-based and field-based research is needed to better understand this complex issue.
