Moana Springs Aquatic Facility
… presents the design for the Moana Springs Aquatic Facility, as part of an ongoing effort by the Sierra Nevada Community Aquatics (SNCA) to build a state-ofthe- art aquatics facility in the Truckee Meadows. The planning and development of the Moana Springs Aquatic Facility intends to serve …

BRIDGING AQUATIC AND TERRESTRIAL ECOSYSTEMS: ECOLOGY OF SEMI-AQUATIC MAMMALS IN SOUTHERN ILLINOIS
Mammals in freshwater aquatic systems play important roles as ecosystem engineers, trophic transfer agents, and apex predators, thus acting as indicators of freshwater ecosystem function. Watersheds inhabited by semi-aquatic mammals have increased links between adjacent terrestrial and aquatic …

Seed Dispersal by Aquatic Turtles
Seed dispersal capabilities by several common aquatic turtles in Southwestern Missouri were investigated. Fecal matter was first obtained during a summer seed survey in which stinkpots (Sternotherus odoratus), river cooters (Pseudemys concinna), spiny soft-shell turtles (Apalone spinifera), and …

Pesticides in the Aquatic Environment
… are ubiquitous contaminants of the freshwater aquatic environment. Pesticide residues are found in varying amounts in all components of the aquatic ecosystem including water, animal and plant tissue and sediments. Organochlorine pesticide residues in water, usually in the parts per trillion …

Novel Bio-inspired Aquatic Flow Sensors
Inspired by the roles of hair cells in nature, this study aims to develop and characterize two new sets of novel flow sensors. One set of sensors developed and studied in this work are flow sensors fabricated using carbon nanomaterials. These sensors are made by embedding carbon nanotubes (CNT) and …

Emydomyces testavorans infection in aquatic chelonians
… lineages, infection has not yet been reported in aquatic turtles. In 2011, however, a previously unreported presentation of shell disease was documented by pathologists at the University of Illinois Zoological Pathology Program (ZPP) from various aquatic turtles in managed care. Shell lesions were …

Digital holographic imaging of aquatic species
… of capturing three-dimensional (3D) images of aquatic species. The images produced by this system are used in a non-intrusive manner to characterize the abundance, morphology and 3D location of the aquatic species. The DHI system operates by recording the hologram produced by the interference …

Aquatic gravity currents through emergent vegetation
… density-driven, lateral exchange flows in aquatic systems. Despite the ubiquity of wetlands and other types of aquatic canopies, few studies have examined the hydrodynamic effects of aquatic vegetation on these currents. This study investigates the dynamics of lock-exchange flows, a …

Uptake of kepone by aquatic macrophytes
Arrowarum [Peltandra virginica (L.) Schott and Endl.], waterhyacinth (Eichhornia crassipes (Mart.) Solms], American bulrush [Scirpus americanus (Pers.)], and smooth cordgrass [Spartina alterniflora (Loisel.)] removed Kepone® (dechachloro-octahydro-1,3,4-metheno-2H-cyclobuta[cd] pentelen-2-one) from …

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 Virtual Reality: From Feasibility to Application
Aquatic virtual reality (VR) is a minimally researched area. VR replaces what a user interacts with and sees with virtual objects and aquatic VR does the same while the user is in an aquatic environment (e.g., a pool) physically. As VR technology is becoming more mobile (e.g., wireless), aquatic VR …

Degradation of microcystin-LR by aquatic bacteria.
Microcystins are cyclic heptapeptide toxins produced by cyanobacteria. They are potentially a threat to human and domestic animals so are of worldwide interest. Microcystin-LR is stable in various environmental conditions. It is important to know the factors affecting microcystin degradation which …

Methane distribution and oxidation across aquatic interfaces
… of the methane cycle in various environments. Aquatic environments are of an exceptional interest due to their active involvement in methane cycling worldwide and in particular in areas sensitive to climate change. Furthermore, being connected with each other aquatic environments form networks …

Aquatic toxicity of one dimensional carbon nanomaterials
This study determined the toxicity of one dimensional carbon nanomaterials (CNMs) to amphipods, midge, oligochaetes and juvenile mussels in water and sediment. As-produced or modified carbon nanotubes (CNTs) and silicon carbide nanowires (SiCNW) were selected to represent CNMs. Sediment tests were …

High-throughput sperm cryopreservation of aquatic species
… of high-throughput sperm cryopreservation to aquatic species. The blue catfish Ictalurus furcatus was selected for research due to its role in production of hybrid catfish with eggs from channel catfish Ictalurus punctatus. A high-throughput cryopreservation pathway was developed by …

Antimicrobial resistance gene monitoring in aquatic environments
… resistance gene (ARG) dissemination in the aquatic environment. The work opens with a review of the relevant literature and outlines the importance of an environmental framework for monitoring ARG dissemination as part of antimicrobial resistance risk assessments. The ability to interrogate …

Aquatic microenvironments in bacterial ecology and diversity
… environment? This study examines the role of aquatic microenvironments in generating bacterial diversity: closely related organisms may co-exist in the same environment without competing for resources by a combination of habitat, metabolic, and behavioral differentiation. This hypothesis has …

Degradation of orthochlorophenol by an aquatic actinomycete
… to determine the growth characteristics of an aquatic actinomycete and to evaluate its potential for degrading o-chlorophenol. Results of the investigation showed that this Streptomyces species has two growth stages, primary and secondary. In the primary stage, growth was restricted to the …
