Interests and Expertise

John Jackson’s research interests span a variety of applied and basic subjects, including population and evolutionary ecology of stream insects, the role of abiotic and biotic processes in determining the structure and function of stream assemblages, energy and nutrient exchange within streams and between streams and their surrounding watersheds, and benthic monitoring and water quality assessment. Specific projects that address these research interests include studies of growth and development of aquatic insects, the influence of dispersal, population dynamics, and environmental variation on genetic structure of stream organisms, the evolutionary and ecological significance of disturbance in aquatic insect ecology, spatial and temporal variation in the distribution and abundance of stream insects, and organic matter dynamics and secondary production. These studies have been located in temperate and/or tropical streams.
