Fish communities in streams of the Maryland-Washington, DC-Virginia developed Piedmont, 2024 Fish communities in streams of the Maryland-Washington, DC-Virginia developed Piedmont, 2024
From May 27 to June 21, 2024, a Virginia Tech team of 5 sampled the fish community in 30 streams spanning a gradient of the developed landscape, including Potomac River, Rappahannock River, and upper Chesapeake Bay tributaries of Maryland, Washington, D.C., and Virginia, USA. These fish surveys were part of a larger stream-health study including other teams who surveyed geomorphology...
Fish communities in PA and MD Piedmont mixed agricultural streams, 2023 Fish communities in PA and MD Piedmont mixed agricultural streams, 2023
From 2-27 June, 2023, a Virginia Tech team of 5 sampled the fish community in 30 Piedmont streams (lower Susquehanna River and upper Chesapeake Bay tributaries, Pennsylvania and Maryland, USA) spanning a gradient of agricultural intensity as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, and macroinvertebrates at...
Fish communities in Delmarva Peninsula streams, 2022 Fish communities in Delmarva Peninsula streams, 2022
From 31 May to 29 June, 2022, a Virginia Tech team of 4-5 sampled the fish community in 30 Delmarva Peninsula streams (Maryland and Delaware, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, macroinvertebrates, and fish health at the same 30 streams. These 30 Chesapeake Bay Watershed tributaries had upstream...
Fish communities in Shenandoah Valley streams, 2021 Fish communities in Shenandoah Valley streams, 2021
From 16 June to 30 July, 2021, a Virginia Tech team of 4-6 sampled the fish community in 30 Shenandoah Valley streams (Virginia and West Virginia, USA) as part of a larger stream-health study including other teams who surveyed geomorphology, water quality, flow, temperature, macroinvertebrates, and fish health at the same 30 streams. The fish community team also sampled three additional...

Igniting the transition from water quality to biological condition and ecological health Igniting the transition from water quality to biological condition and ecological health
Karr (1981), which introduced the index of biotic (or biological) integrity (IBI) has been cited more often (>4,500 times) than any other paper in Fisheries. In this essay, we reflect on the historical context of this seminal publication and its broad, continuing impact on the management of natural resources, especially freshwater ecosystems.

Landowners' cognitions and motivations coupled with practice durability influence persistence in grazing agricultural conservation practices in southwest Virginia Landowners' cognitions and motivations coupled with practice durability influence persistence in grazing agricultural conservation practices in southwest Virginia
Agricultural conservation practices are often used to protect stream health while continuing food production. However, recovery of stream health is often not as rapid or extensive as planned. The efficacy of practices may be improved by promoting their continued use by landowners (i.e., persistence) after cost-share contracts with government agencies end. Persistence rates and their...

Management strategy evaluation to assess trade-offs associated with invasive Blue Catfish fisheries and predation impacts Management strategy evaluation to assess trade-offs associated with invasive Blue Catfish fisheries and predation impacts
Objective Many species are intentionally introduced beyond their native range to provide benefits to humans (e.g., food, recreation, or biocontrol). However, introduced species can become invasive and can harm native species, prompting resource managers to explore options to simultaneously conserve native biota and enhance fishing opportunities. Management of Chesapeake Bay Blue Catfish...

Predicting invasiveness of freshwater fishes imported into North America: Regional differences in models and outcomes Predicting invasiveness of freshwater fishes imported into North America: Regional differences in models and outcomes
Biological invasions driven by international trade heighten the urgency for development of invasion risk models, as the traits and parameters that consistently predict successful invasion remain unresolved. For four regions of North America that include parts of the United States and Canada (Sacramento-San Joaquin River Basins, Lower Colorado River Basin, Great Lakes Region, Mid-Atlantic...

Connecting conservation practices to local stream health in the Chesapeake Bay watershed Connecting conservation practices to local stream health in the Chesapeake Bay watershed
The Chesapeake Bay Partnership is implementing conservation practices (CPs) throughout the Chesapeake Bay watershed to reduce nutrient and sediment delivery to the Bay. This study intends to provide an integrated and detailed understanding of how local streams respond to these CP-driven management efforts. Key issue: To what extent do CPs positively affect the health of local streams in...

Deposited sediment influences occurrence of functional traits of stream fishes Deposited sediment influences occurrence of functional traits of stream fishes
To better understand stream-fish sensitivity to fine sediment, we documented assemblage-wide responses by selected traits along a sedimentation gradient. We then discuss the management implications of these ‘dose–response’ relations in the contexts of biotic assessments and conservation of sediment-sensitive species. We identified a spatial gradient in sediment deposition among streams...
