Relieving phosphorus loading is a key management tool for controlling Lake Erie eutrophication. During the 1960s and 1970s, increased inputs degraded water quality reduced central basin hypolimnetic oxygen levels which, in turn, eliminated thermal habitat vital to cold-water organisms contributed extirpation of important benthic macroinvertebrate prey species fishes. In response load reductions initiated 1972, responded quickly with water-column concentrations, phytoplankton biomass,...
1. Hypoxia occurs seasonally in many stratified coastal marine and freshwater ecosystems when bottom dissolved oxygen (DO) concentrations are depleted below 2–3 mg O2 L−1. 2. We evaluated the effects of hypoxia on fish habitat quality central basin Lake Erie from 1987 to 2005, using bioenergetic growth rate potential (GRP) as a proxy for quality. compared effect (i) rainbow smelt, Osmerus mordax Mitchill (young-of-year, YOY, adult), cold-water planktivore, (ii) emerald shiner, Notropis...
Unmanned aerial vehicles (UAV) are increasingly used for spatiotemporal monitoring of invasive plants in coastal wetlands. Early identification species is necessary planning, restoring, and managing This study assessed the effectiveness UAV technology to identify Phragmites australis Old Woman Creek (OWC) estuary using machine learning (ML) algorithms: Neural network (NN), support vector (SVM), k-nearest neighbor (kNN). The ML algorithms were compared with parametric maximum likelihood...
Ecologists increasingly recognize the need to understand how landscapes and food webs interact. Reservoir ecosystems are heavily subsidized by nutrients detritus from surrounding watersheds, often contain abundant populations of gizzard shad, an omnivorous fish that consumes plankton detritus. Gizzard shad link terrestrial pelagic reservoir consuming detritus, translocating sediment water column, zooplankton. The abundance increases with watershed agriculturalization, most likely through a...
Due to their low light conditions, shadows reduce the accuracy of feature extraction and change detection in remote-sensing images. Unmanned aerial vehicles (UAVs) are capable acquiring images that have a resolution several centimetres removing is challenge. In this study, Maximum Likelihood (ML) Support Vector Machine (SVM) classifiers were used classify UAV image acquired using red–green–blue (RGB) camera over Old Woman Creek National Estuarine Research Reserve Ohio, USA. The impact on...
Although effects of land use/cover on nutrient concentrations in aquatic systems are well known, half or more the variation concentration remains unexplained by alone. Hydrogeomorphic (HGM) landscape features can explain much remaining and influence food web interactions. To explore complex linkages among use/cover, HGM features, reservoir productivity, webs, we sampled 11 Ohio reservoirs, ranging broadly agricultural catchment for 3 years. We hypothesized that mediate bottom‐up chlorophyll...
More fish have been afforded US Endangered Species Act protection than any other vertebrate taxonomic group, and none has designated as recovered. Shortnose sturgeon (Acipenser brevirostrum) occupy large rivers estuaries along the Atlantic coast of North America, species protected by since its enactment.
Habitat assessment is an important form of management for species conservation, mitigation planning, environmental regulation, and impact assessment. As part American Fisheries Society U.S. Fish Wildlife Service project, we surveyed state, provincial, federal, private organizations to obtain documentation about methods being used assess aquatic habitats in the inland waters North America. We then this information characterize attributes established methods. found that most target associated...
Mapping land and aquatic vegetation of coastal areas using remote sensing for better management conservation has been a long-standing interest in many parts the world. Due to natural complexity heterogeneity cover, various sensors techniques are utilized monitoring ecosystems. In this study, two unsupervised supervised standard pixel-based classifiers were tested evaluate mapping performance second-generation airborne NASA Glenn Hyperspectral Imager (HSI2) over narrow area along Western Lake...
We explored how embayment watershed inputs, morphometry, and hydrology influence fish community structure among eight embayments located along the southeastern shoreline of Lake Ontario, New York, USA. Embayments differed in surface area depth, varied their connections to Ontario watersheds, drained watersheds representing a gradient agricultural forested land use. related various physicochemical factors, including total phosphorus load, area, submerged vegetation, differences species...
Abstract Several pyridine derivatives including the pesticide nitrapyrin [2-chloro-6-(trichloromethyl) pyridine] are strong inhibitors of methane monooxygenase, a key enzyme aerobic (CH 4 ) oxidation. In this study we examined effects 2-chloro-6-methylpyridine (2C6MP) concentration on CH oxidation and development populations putative methanotrophs in sediment from Old Woman Creek, freshwater estuary Huron Co., Ohio. Experimental systems were prepared serum bottles containing minimal medium...
