Fish mercury (Hg) data were compiled for 392 unique locations on freshwater streams and rivers in New York State for the period 1969-2016. A total of 7620 records were compiled from state, federal, and non-governmental organization databases. The compiled data were for samples of 65 non-anadromous species or species groups in which Hg was analyzed in whole fish or edible flesh, and for which sufficient ancillary data were available for interpretation. This data release provides total Hg concentrations on a wet weight basis, ancillary sample data (e.g., fish length, body part analyzed), collection location information (description, latitude, longitude), and source of original data. The data release also contains...

Fish in Northern Great Plains streams evolved to survive heat, cold, floods and drought; however changes in streamflow associated with long-term climate change may render some prairie streams uninhabitable for current fish species. To better understand future hydrology of these prairie streams, the Precipitation-Runoff Modeling System (PRMS) model and output from the RegCM3 Regional Climate model were used to simulate streamflows for seven watersheds in eastern and central Montana, for a baseline period (water years 1982 - 1999) and three future periods: water years 2021 -2038, 2046 - 2063, and 2071 - 2088. These PRMS model input and output data are intended to accompany a journal article (Chase et al., 2016); they...

This project addressed regional climate change effects on aquatic food webs in the Great Lakes. We sought insights by examining Lake Erie as a representative system with a high level of anthropogenic impacts, strong nutrient gradients, seasonal hypoxia, and spatial overlap of cold- and cool-water fish guilds. In Lake Erie and in large embayments throughout the Great Lakes basin, this situation is a concern for fishery managers, as climate change may exacerbate hypoxia and reduce habitat volume for some species. We examined fish community composition, fine-scale distribution, prey availability, diets, and biochemical tracers for dominant fishes from study areas with medium-high nutrient levels (mesotrophic, Fairport...

The Large River Monitoring Forum compiled fish assemblage data for five large rivers in the U.S. as a part of a coordinated effort to compare and contract river monitoring efforts in large river systems. Fish community data from five monitoring programs were integrated to create the standardized dataset. Authors: Timothy D. Counihan1, Ian R.

This collection contains numerous zoological specimens from the southwestern United States. Specimens were collected beginning in the 1920s through 2013 and include mammals, fish, birds, amphibians, and reptiles. This is a legacy collection that was transferred to the USGS from the U.S. Fish and Wildlife Service (FWS) in 1996 when the unit that would become the Biological Resources Division became part of the USGS. Specimens were accessioned as museum property in 2002, 2003, and 2006. The collection contains voucher specimens of vertebrates collected on Federal land in the western United States. It is administered by the USGS Fort Collins Science Center and housed at the Museum of Southwestern Biology at the University...
