Climate Change and Aquatic Bugs

Climate change is no longer a distant threat-it is an unfolding reality. Rising temperatures, acidification, sea-level rise, and extreme weather events are reshaping global ecosystems at an unprecedented scale. Among the most sensitive yet overlooked indicators of this crisis are aquatic bugs (Hemiptera), inhabiting both freshwater and marine environments. This book offers a comprehensive synthesis of how climate change affects these vital insects. It explores natural and human-driven causes of climate change and examines impacts on aquatic biodiversity: altered emergence patterns, behavioral responses, metabolic changes, sex ratio shifts, geographic redistribution, and extinction risks. Aquatic bugs are powerful bio-indicators. Their presence or absence reveals the true health of streams, ponds, and coastal waters. Bridging physiology, ecology, and biogeography, this volume delivers a clear message: understanding these small creatures is essential for predicting and mitigating the broader impacts of global climate change on all aquatic life. Essential reading for entomologists, limnologists, climate researchers, and conservation biologists.
