The Potential Effects of Unconventional Oil and Gas Development on Eastern Brook Trout
Issue The Upper Susquehanna River watershed (PA) has experienced a rapid increase in unconventional oil and gas (UOG) development since it is part of the Marcellus shale formation. It is also part of the headwaters of the Chesapeake Bay, which is the focus of considerable conservation and restoration activities by federal and state agencies under the Chesapeake Bay Watershed Agreement. Brook trout...
Forecasting the Effects of Land-Use and Climate Change on Wildlife Communities and Habitats in the Lower Mississippi Valley
This project built on an existing regional conservation partnership to use the most recent downscaled climate model projections to forecast the likely impacts of climate change to species and ecosystems in the Lower Mississippi Valley (LMV). The objective of this work was to develop and test ecological and biological models to facilitate regional adaptive management of wildlife resources...

Appendix D: Synthesis element 1 (revised): Water temperature effects on fisheries and stream health in nontidal waters Appendix D: Synthesis element 1 (revised): Water temperature effects on fisheries and stream health in nontidal waters
A limited review of relevant scientific literature related to temperature sensitivities of fish species, stream health indicators, and any related geospatial information was conducted. Based on this review, we provide a syntheses of information related to nontidal waters in the Chesapeake Bay Rising stream temperatures will have a range of impacts on nontidal aquatic ecosystems. Cold...

Understanding genetics for successful conservation and restoration of resilient Chesapeake Bay brook trout populations Understanding genetics for successful conservation and restoration of resilient Chesapeake Bay brook trout populations
Traditionally, fisheries management has focused on the abundance, distribution, and size structure of populations. Although these factors remain key aspects of management, a large and growing body of evidence highlights the importance of genetics in conserving wild populations, especially when populations are small and isolated (Frankham et al. 2017). Local adaptations are very common...

Brook trout distributional response to unconventional oil and gas development: Landscape context matters Brook trout distributional response to unconventional oil and gas development: Landscape context matters
We conducted a large-scale assessment of unconventional oil and gas (UOG) development effects on brook trout (Salvelinus fontinalis) distribution. We compiled 2231 brook trout collection records from the Upper Susquehanna River Watershed, USA. We used boosted regression tree (BRT) analysis to predict occurrence probability at the 1:24,000 stream-segment scale as a function of natural and

A detailed risk assessment of shale gas development on headwater streams in the Pennsylvania portion of the Upper Susquehanna River Basin, U.S.A. A detailed risk assessment of shale gas development on headwater streams in the Pennsylvania portion of the Upper Susquehanna River Basin, U.S.A.
The development of unconventional oil and gas (UOG) involves infrastructure development (well pads, roads and pipelines), well drilling and stimulation (hydraulic fracturing), and production; all of which have the potential to affect stream ecosystems. Here, we developed a fine-scaled (1:24,000) catchment-level disturbance intensity index (DII) that included 17 measures of UOG capturing...

Executive Summary The U.S. Geological Survey (USGS) has the critical role of providing scientific information to improve the understanding and management of the Chesapeake Bay ecosystem. The USGS works with Federal, State, and academic science partners to provide research and monitoring, and communicate results of these activities to enhance ecosystem management for both the Chesapeake...

Understory vegetation as an indicator for floodplain forest restoration in the Mississippi River Alluvial Valley, U.S.A. Understory vegetation as an indicator for floodplain forest restoration in the Mississippi River Alluvial Valley, U.S.A.
In the Mississippi River Alluvial Valley (MAV), complete alteration of river-floodplain hydrology allowed for widespread conversion of forested bottomlands to intensive agriculture, resulting in nearly 80% forest loss. Governmental programs have attempted to restore forest habitat and functions within this altered landscape by the methods of tree planting (afforestation) and local...
