Time marches on, but do factors driving instream habitat and biology remain consistent?

Issue: Stream ecosystems are affected by a complex set of interacting terrestrial and aquatic stressors. With many streams experiencing degraded conditions that often correspond with increased anthropogenic activities, an important outcome of the Chesapeake Bay Program is to improve stream health. The USGS is conducting research to better understand the complex factors affecting stream health...

Use of Structured Decision Making to Optimize Salt Marsh Management Decisions at Northeastern National Wildlife Refuges

US Fish and Wildlife Service completed a regional assessment of salt marsh integrity (SMI) on 15 National Wildlife Refuges/Refuge Complexes in the northeastern US. Developed within a structured decision making (SDM) framework, the SMI assessment provides essential baseline data on salt marsh condition relative to regional management objectives. These data now provide the basis for applying the SDM...

The response of coastal wetlands to sea-level rise: Understanding how macroscale drivers influence local processes and feedbacks

The purpose of this work is to advance our understanding of how coastal wetland responses to SLR within the conterminous United States are likely to vary as a function of local, regional, and macroscale drivers, including climate. Based on our interactions with managers and decision makers, as well as our knowledge of the current state of the science, we propose to (a) conduct a national synoptic...

Virginia Coast Reserve Long Term Ecological Research VII

The highly protected Virginia Coast Reserve (VCR) is the largest undeveloped region along the Atlantic seaboard.The VCR is managed by the Nature Conservancy, and was designated a Man and the Biosphere Reserve in 1979, providing a unique environment for which to study coastal impacts of climate change on a variety of coastal ecosystems from barrier islands across back barrier lagoons, mudflats...

Assessing Faunal Recovery in a Headwater Stream

A catastrophic fish-kill in a small tributary stream of the Etowah River system (Dawson County, Georgia) has created the opportunity to assess faunal recovery, including recolonization by a federally-listed fish species (the Cherokee darter Etheostoma scotti). Fishes are expected to recolonize Flat Creek by moving upstream from downstream sources. In particular, Flat Creek flows into a larger...

Seagrass Vulnerability to Environmental Conditions Under Changing Temperature Regimes

Seagrasses are among the most productive ecosystems on the planet. Water quality degradation and direct human disturbance have caused loss of nearly a third of the seagrass habitat worldwide. These threats are exacerbated by stresses associated with a changing global climate. Predicting how seagrass distribution, abundance, and species composition will change in response to increased temperature...

Mapping riverine habitats of the Delaware River using bathymetric LiDAR

Ecosystem management and assessment of rivers requires detailed data on bathymetry before estimates of aquatic habitats can be determined. However, mapping bathymetry in shallow rivers is challenging due to river depth limitations for watercraft.

Assessing stream health and fish habitat in streams of the Chesapeake Bay Watershed

Streams and rivers provide habitat for a diverse array of aquatic and semi-aquatic species. However, human alteration to landscapes and riverscapes has affected this habitat resulting in its degradation and thus loss of habitat and associated sensitive aquatic species. While this relationship has been known for many years, only recently has the availability of data and analytical capabilities...

Brook trout vulnerability to drought: eastern component of USGS national integrated ecohydrological research and monitoring plans

There is a growing and urgent need to develop and implement innovative strategies to research, monitor, and manage freshwater resources as societal demands escalate simultaneously with climate-driven changes in water availability.

A hydrological framework to improve precision of Vital Signs metrics in the Appalachian highlands

Stream flow is a fundamental driver of ecological structure and function, but its influence on bioassessment measures is poorly understood. Although extreme flow conditions (e.g., floods and droughts) have long been known to play a central role in structuring stream communities, a mechanistic understanding of the linkages between flow variables, landscape and local physical characteristics, and...
