Fish locomotion and biomechanics as limiting and optimizing factors in fish passage

Swimming ability determines how well fish are able to access habitat, and is a fundamental design consideration for passing fish at dams, road crossings etc.  The purpose of this study plan is to improve understanding of how fish are able to negotiate zones of high velocity and turbulent flow, such as are found in fishways, culverts, as well as in natural areas.   Swimming performance is...

Climate change forecasts for eastern salmonids

Small streams in forests are likely to see dramatic shifts as global climate change influences air temperature and rain patterns. We have already seen warmer stream temperatures as air temperatures increase in summer in the Northeastern US. The intensity and duration of floods and droughts are also expected to magnify as future rain patterns shift. This project will evaluate how stream...

San Francisco Bay Basic Tide Model

This web page provides files that may be used to run a basic depth-averaged (2DH) Deltares Delft3D version 4.00.01 astronomic tide model for San Francisco Bay. It was developed with the primary aim of assessing water level fluctuations and flow conditions in the vicinity of the Golden Gate (Elias and Hansen 2013).

Developing and testing eDNA markers for the Federally endangered dwarf wedgemussel, Alasmidonta heterodon and other key freshwater mussel species

Dwarf wedgemussel is a federally endangered freshwater mussel with a historic range spanning the Atlantic coast. However, populations have dramatically declines over the last 30 years.  Therefore, knowledge of current population distribution and abundance is critical to resource managers in order to monitor the species over time and to guide recovery actions. Manual survey efforts (snorkel or...

Metabarcoding of stomach contents from the Round Goby (Negobius melanostromus) in Pennsylvania

The Round Goby, Neogobius melanostomus, is a small benthic fish native to the Sea of Azov, the Caspian Sea, the Black Sea and the Sea of Marmara. The first round goby found in the Pennsylvania waters was in 1996. Since then, round gobies are now the dominant benthic fish in many of the tributary streams in the Pennsylvanian waters of Lake Erie, including French Creek. French Creek is...

Improving ecological flow science in the mainstem Delaware through WaterSMART

Demand for freshwater is increasing with human population growth and is exacerbated by water management practices, climate variability, and land use alternation.  Ecological flow science attempts to understand flows necessary to support aquatic organisms so that managers can balance these with diverse human water demands.  A primary focus of the USGS Northern Appalachian Research Laboratory (...

Development of fine-scale temperature models in the Delaware River: Application to predictive temperature modeling, decision support tools, and ecosystem services

Temperature is a primary driver of biological and ecological processes, and in rivers and streams influences distribution, reproduction, and behavior of aquatic species.  USGS Northern Appalachian Laboratory (NARL) researchers are working with resource managers in the Delaware River Basin and collaborators at USGS Fort Collins Science Center to predict and model riverine temperature,...

Species Data Web Services

Species habitat maps are available in an Open Geospatial Consortium (OGC) Web Map Service (WMS).  Each species’ habitat map or range map is a layer in the respective WMS, referenced by the species' common name (scientific name) species code and version.  At this time all maps are version 1 (v1).
