Interests and Expertise
Bernard Sweeney’s interests include the role of water quality monitoring in conservation, population and community ecology of temperate and tropical aquatic invertebrates; pollution assessment in temperate and tropical streams using macroinvertebrates; the role of streamside forests in the structure and function of stream and river ecosystems; factors affecting the growth and survivorship of trees in riparian forests; the effects of global warming on stream ecosystems; genetic variation and gene flow among populations of stream insects; the effects of diel and seasonal temperature change on aquatic insect populations; evolution of facultative parthenogenesis in aquatic insects; bioenergetics and secondary production of aquatic insects; and the bioassay of toxic materials in aquatic systems.
