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...

Using Advanced Technology to Enhance Research at the Patuxent Wildlife Research Center (PWRC) - a Public-Private Partnership

This project is focused on exploring the use of new technology to collect data on colonially nesting waterbird species in ways that reduce disturbance, improve data accuracy, or allow for the examination of previously unanswerable questions.

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...

Exploring the potential effects of shale oil and gas development on freshwaters

Widespread shale oil and gas (unconventional oil and gas, UOG) has only recently begun and many gaps in our knowledge of its potential effects to freshwaters exist.

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...

Assessment of the immune status of wild and laboratory-maintained smallmouth bass

Deaths of young-of-year smallmouth bass in the Chesapeake Bay drainage has been noted since 2005. Studies of affected fish have found bacterial, viral and parasitic infections. Mixed infections suggest these fish are immunosuppressed. Understanding the role of specific pathogens and environmental factors that contribute to their presence is important but equally important is the understanding of...
