We present a technical analysis of all the recent modelling work that has been conducted to support adaptive management process in Lake Erie; most biologically productive system Great Lakes. With wealth models developed, Erie represents unique case study where an impressive variety data-driven and process-based have developed elucidate major watershed aquatic processes underlying local water quality problems. In Maumee River watershed, primary contributor total phosphorus loading (~30%) into...
In Lake Erie, a wide variety of statistical and process-based models have significantly advanced our understanding the major causal linkages/ecosystem processes underlying local water quality problems. this study, aim is to identify knowledge gaps, monitoring assessment objectives, management recommendations that should be critically reviewed through iterative monitoring-modelling-assessment cycles adaptive management. watershed, presence multiple SWAT applications provides assurance array...
Mercury (Hg) sequestration by phytoplankton results in intracellular concentrations that are multiple times greater than ambient water levels, and therefore the consumption of contaminated herbivorous zooplankton, such as Daphnia, their inefficient excretion methylmercury (MeHg) can mediate transfer to higher trophic levels. Employing a modified version metabolomics-inspired Daphnia ecophysiological model, present study introduces two prey species simple Lotka-Volterra predator-prey system...
Hydropower generation, a renewable source of electricity, has been linked to elevated methylmercury (MeHg) concentrations in impoundments and aquatic biota. This study investigates the impact water level fluctuations (WLF) on MeHg water, sediment, fish. Using set controlled microcosm experiments emulating drawdown/refill dynamics subsequent sediment exposure air experienced reservoirs, we demonstrate that less frequent WLFs, and/or increased air, can lead total mercury (THg) water. In...
Humans have now altered essentially every natural ecosystem in the world, and among numerous consequences of anthropogenic global change, many Earth’s species are currently living under drastically different environmental ecological conditions. On one hand, that once thrived wild threatened by extinction, while at same time, were historically benign becoming invasive parts world. To address this major challenge, it is critical conservation practitioners understand multiple short- long-term...
