Aquatic Community Interaction Diversity and Mosquito Larvae
… flying insects,mosquitoes undergo an entirely aquatic life cycle as developing larvae and pupae.During these developmental stages immature mosquitoes are most vulnerable topredation and competition for resources. Their habitats are highly variable in manyfactors including size, invertebrate …

Aquatic community response to Zequanox®: a mesocosm experiment
… and predation. Using a six-week-long replicated aquatic mesocosm experiment, I simulated open-water applications of Zequanox® (100 mg/L of the active ingredient) to determine the responses of primary producers, zooplankton, and macroinvertebrates to Zequanox® exposure in a complex aquatic …

Response of a cave aquatic community to groundwater pollution
… effluent may provide additional food to the aquatic community in Banners Corner Cave, but generally was damaging to the system.

Using Benthic Indicator Species and Community Gradients to Optimize Restoration in the Arid, Endorheic Walker River Watershed, Western USA
… and identify opportunities and constraints for aquatic community restoration. Naturally harsh environments in the lower river characterized by high temperatures and low base flow combined with a weak understanding of reference conditions to limit the utility of commonly used indices for …

Effects of Supraseasonal Drought on Karst Aquatic Communities of the Edwards Plateau
… of a supraseasonal drought (2022 – 2024) on aquatic habitats, mussel assemblage, and fish assemblage within headwater (N = 6 sites), mainstem (N = 10 sites), and tributary (N = 4 sites) reaches of the upper Guadalupe River. At the start of an exceptional drought in 2022 and through 2024, …

Salmonids in an Urban Stream: Movement, Habitat, and Potential Barriers
… salmonid densities and the diversity of the fish community demonstrate that small scale restoration projects can benefit the aquatic community.

The effects of the invasive exotic Chinese tallow tree (Triadica sebifera) on amphibians and aquatic invertebrates
… litter from trees affects animals that live in aquatic environments, with an emphasis on the effect of Chinese tallow (Triadica sebifera) leaf litter on anuran larvae (i.e., frog tadpoles). This question is important to our understanding of how allochthonous inputs to aquatic habitats drive …

Environment risk assessment for toxic chemicals and genetically-engineered microorganisms: a microcosm approach
… and effect on structure and function of aquatic microcosms. Densities of genetically-engineered and wild type E. carotovora declined at the same rate in water or in sediment, falling in 32 days below the level of detection by viable counts. Selective media, antibiotic resistance, and most …

Striped Bass and Summer Flounder Population Dynamics in the Chesapeake Bay: an Ecosystem Based Evaluation
… of striped bass, summer flounder and the aquatic community we set out to identify the environmental drives of their abundance changes from local to global scales. The fish community in the Bay has previously shifted due to environmental perturbations, so we also investigate if the …

Bivalve molluscs as environmental monitors and tools for sustainable water management
… is lacking. This has encouraged the use of aquatic biota to provide direct information on the ecological state of a waterway. Such monitoring is beneficial, both to the protection of the health of aquatic ecosystems, and the human populations that rely upon them. Bivalve molluscs offer …

Assessing nearshore water quality and biological condition in the Kawartha Lakes using a community science approach
… scale. I also monitored the nearshore biotic community (phytoplankton, zooplankton, and macroinvertebrates) at eight sites in Lake Scugog. Two years of sampling found that macrophyte abundance significantly influenced the phytoplankton, zooplankton, and macroinvertebrate communities. During …
