Are aquatic food webs vulnerable to copper and gold engineered nanoparticles?
… My work during this study determined decreased insect emergence in nanoparticle treatments, aquatic to riparian metal export via aquatic insect emergence, and subsequent metal accumulation in riparian spiders. In that same study, I demonstrated that consumers exposed to nanoparticles doubled …

Aquatic community response to Zequanox®: a mesocosm experiment
… large cladoceran grazers (700% of controls), and insect emergence (490% of controls). Large declines initially occurred among small cladoceran zooplankton (88–94% reductions in Chydorus sphaericus, Ceriodaphnia lacustris, and Scapheloberis mucronata), but abundances generally rebounded within …

Assessing the Effects of Chronic Neonicotinoid Insecticide Exposure on Aquatic Insects using Multiple Experimental Approaches
Neonicotinoid insecticides are among the most widely used plant protection products in industrialized agriculture, and are hypothesized to be contributing to losses in non-target insect biodiversity. The lack of toxicological data evaluating the effects of neonicotinoids restricts the ability of …

The influences of hydrology and vegetation on emergent insect and benthic macroinvertebrate communities across space and time in seasonally inundated, geographically isolated wetlands
… of aquatic macroinvertebrates, including insects that serve as energy in upland food webs when they emerge as adults. How aquatic macroinvertebrate communities, particularly emergent aquatic insects, respond to vegetation and differences in long-term patterns of water permanency in …

RESOURCE SUBSIDIES ACROSS THE AQUATIC-TERRESTRIAL BOUNDARIES OF TEMPORARY PONDS
… inputs, 2) amphibian egg inputs, 3) terrestrial insect inputs, 4) amphibian metamorph emergence, and 5) aquatic insect emergence for eight temporary ponds. Terrestrial insect inputs to ponds represented substantial high-quality subsidies to ponds that are generally unaccounted for in similar …

Quantifying changes in macroinvertebrate community composition, biomass, and emergence in response to mining-induced salinization in central Appalachian streams
… the extent of loss is uncertain, especially for insects that use freshwater during their life. Further study is needed to assess freshwater insect abundances and diversity. In Central Appalachian streams, macroinvertebrate diversity declines in response to mining-induced salinization and …

Incorporating biotic interactions in phenology
… bird migration, leaf unfolding, flowering, and insect emergence, across many taxa and ecosystems are a result of climate change. Phenological shifts depend on different factors and species-specific sensitivity to changes in meteorological variables, therefore when phenological shifts occur …
