Barry P Baldigo
Barry Baldigo has been a Research Biologist with the U.S. Geological Survey since 1990. He leads numerous collaborative studies that aim to improve our understanding of the health of aquatic ecosystems, impacts of environmental contaminants and hydrologic modification, important interrelations, and management options that help mitigate ecological disturbance and sustain valuable natural resources.

Adirondack Long-Term Stream and Soil Monitoring
The current Adirondack Long-Term Monitoring Program combines monitoring of streams and soils based on a watershed design. Not only are headwater streams an important component of Adirondack ecosystems, they are closely tied to the terrestrial environment through runoff that is strongly influenced by soil and vegetation processes. This linkage makes headwater streams a useful tool for...
Status of benthic macroinvertebrate communities and toxicity of sediments in the Eighteenmile Creek Area of Concern, New York
Background: The USGS propose a collaborative investigation with the NYSDEC to evaluate the current condition of benthic macroinvertebrate communities and toxicity of bed sediments in the Eighteenmile Creek Area of Concern (AOC). Sediment-toxicity data provided by the USGS and benthic-community data provided by the NYSDEC from inside the AOC will be compared to similar data from non-AOC...
Status of benthic macroinvertebrate communities and toxicity of sediments in the Niagara River Area of Concern, New York
Background: The USGS propose a collaborative investigation with the NYSDEC and NOAA to evaluate the current condition of benthic macroinvertebrate communities and toxicity of bed sediments in the Niagara River Area of Concern (AOC). Using a probabilistic study design, sediment-toxicity data compiled by the USGS, invertebrate community data collected by NYSDEC, and sediment-chemistry data
Effects of Watershed and In-stream Liming on Accelerated Recovery of Macroinvertebrate Assemblages in Tributaries to Honnedaga Lake
Background Acidification of lotic and lentic environments has been found to adversely affect the integrity of resident biological assemblages. These effects have been particularly severe in poorly buffered regions like the Western Adirondacks. Although the Clean Air Act and its amendments have greatly reduced levels of atmospheric deposition, many streams in this region are still...
Effects of acid-base chemistry on biology of streams in the Great Smoky Mountains National Park
Background Watersheds of the Great Smoky Mountains National Park (GRSM) receive high levels of acid deposition resulting from atmospheric emissions of nitrogen and sulfur oxides. Acidic deposition has been shown to reduce acid neutralizing capacity (ANC) and calcium concentrations and increase acidity and aluminum concentrations in soils and surface waters and affect forest health as...
Emerging Methods for Detection and their Potential for Inventorying Brook Trout Populations in Streams of the Western Adirondacks
Background Deoxyribonucleic acid (DNA) is the hereditary material in organisms that contains the biological instructions for building and maintaining them. The chemical structure of DNA is the same for all organisms, but differences exist in the order of the DNA building blocks, known as base pairs. Unique sequences provide a means to identify individual species and detect their presence...
