Our research focuses on understanding how freshwater communities and food webs respond to global change, with a special emphasis on the effects of hydrologic alteration and drought.
The relative effects of hydrologic disturbance, abundance of root parasites, and ambient physicochemical conditions on total biomass, biomass allocation, and architecture of the emergent macrophyte Justicia americana (L).
The effects of hydrologic cycle change (caused by human activity and global climate change) on ecosystems attract the increasing attention around the world.
Water managers need quantitative information on the effects of hydrologic alteration on aquatic biota to guide ecologically sensitive water management strategies such as water releases from dams.
The effects of hydrologic design elements incorporated during the construction (i.e., disking-induced microtopography MT and site level elevation difference) on vegetative and hydrologic attributes (e.g., species richness, biodiversity, plant cover, floristic quality assessment index, wetland indicator status, soil moisture content, and water table depths) were investigated.
This paper examines the effects of hydrologic model parameterization uncertainty or equifinality, where multiple unique hydrologic model parameter sets can result in adequate calibration metrics, on hydrologic projections from downscaled GCMs for three snowmelt-dependent watersheds (upper reaches of the Clearwater, Gunnison, and Sacramento River watersheds) in the western United States.
As part of an ongoing study to investigate the effects of hydrologic restoration on short hydroperiod marshes of the southern Everglades, we report an ecosystem characterization of seasonally flooded tree islands relative to locations described by variation in freshwater flow (i.e. locally enhanced freshwater flow by levee removal).
The analysis of the long-term geochemical changes in CMDs in the anthracite field and the effect of the hydrologic setting on water quality presented in this paper can help prioritize CMD remediation and facilitate selection and design of the most appropriate treatment systems.
Storm effects on hydrologic patterns demonstrated with the simulations show hydrologic processes that could have a long-term effect on vegetation change.
A key question is what the effects of these hydrologic changes will be on the crocodile population.
