Scott George

Scott George is a biologist in the Watersheds Research Section of the USGS New York Water Science Center in Troy, NY. 

He recently completed a master's degree at the State University at Albany (SUNY) in Ecology and Evolutionary Biology on the impact of severe flooding on lotic biota. Scott's current research is aimed at better understanding riverine fish, benthic macroinvertebrate, and periphyton communities and the disturbances that impact them. Specific ongoing projects include monitoring the expansion of Round Goby towards the Hudson River using environmental DNA and other methods, studying the recovery of fish assemblages in acid-impacted Catskill Mountain streams, and evaluating the toxicity of sediments to benthic macroinvertebrates in Great Lakes Areas of Concern.

Responses of fish assemblages to changing environmental conditions in the Neversink River and Rondout Creek

Problem The Neversink River and Rondout Creek are historic trout fishing and recreational streams in the heart of the Catskill Mountains of southeastern NY. Waters throughout upper reaches of both rivers currently range from neutral to severely acidic due to deposition of acid rain throughout their watersheds.

Survey of fish assemblages in the upper Neversink River and upper Rondout Creek, New York, 2017–19 Survey of fish assemblages in the upper Neversink River and upper Rondout Creek, New York, 2017–19

Streams in the Catskill Mountains region of New York provide many important ecological and economic services, including recreational angling and serving as a drinking water supply to New York City. Many streams in this region were adversely affected by acid deposition during the late 20th century, impairing water quality and aquatic ecosystems. More recently, the level of acid deposition...

Considerations of variability and power for long-term monitoring of stream fish assemblages Considerations of variability and power for long-term monitoring of stream fish assemblages

Little attention has been given to optimizing statistical power for monitoring stream fish assemblages. We explored the relationship between temporal variability and statistical power using 34 metrics from fish community data collected annually at six sites over 10 years via electrofishing. Metric variability differed by the life stage and group of species considered, use of abundance or...

The Round Goby Neogobius melanostomus has spread rapidly around the Great Lakes region since its introduction to North America in 1990. In 2014, a specimen was captured in the New York State Canal System west of Utica, prompting concerns that Round Goby would soon reach the ecologically and economically valuable watersheds of Lake Champlain and the Hudson River estuary.

Decades of acidic deposition have adversely affected aquatic and terrestrial ecosystems in acid-sensitive watersheds in parts of the eastern United States. The national Acid Rain Program (Title IV of the 1990 Clean Air Act Amendments - CAAA) helped reduce emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) and resulted in sharp decreases in the acidity of atmospheric deposition...
