Flood- and drought-related natural hazards activities of the U.S. Geological Survey in New England Flood- and drought-related natural hazards activities of the U.S. Geological Survey in New England
The U.S. Geological Survey (USGS) has many ongoing and recent water-related natural hazard activities in New England that can be used to help mitigate the effects of natural hazards in cooperation with other agencies. The themes related to potential hazards and the tools and science to better understand and address them include the following: Erosion and landslides • Fluvial erosion...

Surface water-quality activities of the U.S. Geological Survey in New England Surface water-quality activities of the U.S. Geological Survey in New England
The U.S. Geological Survey (USGS) collaborates with a variety of Federal, State, local, and tribal partners on scientific projects to provide reliable and impartial water-quality data and interpretation to resource managers, planners, stakeholders, and the general public. The themes related to surface water quality include the following: • Water quality monitoring networks • Effects of...

Climate Change Science Activities of the U.S. Geological Survey in New England Climate Change Science Activities of the U.S. Geological Survey in New England
The U.S. Geological Survey (USGS) has actively pursued research in the effects of climate change on the hydrology of New England. Ongoing focus areas of climate change science activities of the USGS in New England include the following: • Hydrologic climate-response data (initiating or expanding long-term hydrologic climate-response data collection networks to detect and monitor climate...

Pathways of fish invasions in the Mid-Atlantic region of the United States Pathways of fish invasions in the Mid-Atlantic region of the United States
Non-native fish introductions are a major threat to biodiversity and fisheries, and occur through numerous pathways that vary regionally in importance. A key strategy for managing invasions is to focus prevention efforts on pathways posing the greatest risk of future introductions. We identified high-risk pathways for fish establishment in the Mid-Atlantic region of the United States...

Contact heterogeneities in feral swine: implications for disease management and future research Contact heterogeneities in feral swine: implications for disease management and future research
Contact rates vary widely among individuals in socially structured wildlife populations. Understanding the interplay of factors responsible for this variation is essential for planning effective disease management. Feral swine (Sus scrofa) are a socially structured species which pose an increasing threat to livestock and human health, and little is known about contact structure. We...

Seasonal response of ghrelin, growth hormone, and insulin-like growth factor I in the free-ranging Florida manatee (Trichechus manatus latirostris) Seasonal response of ghrelin, growth hormone, and insulin-like growth factor I in the free-ranging Florida manatee (Trichechus manatus latirostris)
Seasonal changes in light, temperature, and food availability stimulate a physiological response in an animal. Seasonal adaptations are well studied in Arctic, Sub-Arctic, and hibernating mammals; however, limited studies have been conducted in sub-tropical species. The Florida manatee (Trichechus manatus latirostris), a sub-tropical marine mammal, forages less during colder temperatures...

Ecological requirements for pallid sturgeon reproduction and recruitment in the Missouri River—Annual report 2014 Ecological requirements for pallid sturgeon reproduction and recruitment in the Missouri River—Annual report 2014
The Comprehensive Sturgeon Research Project is a multiyear, multiagency collaborative research framework developed to provide information to support pallid sturgeon recovery and Missouri River management decisions. The project strategy integrates field and laboratory studies of sturgeon reproductive ecology, early life history, habitat requirements, and physiology. The project scope of...

Hydrologic controls on nitrogen cycling processes and functional gene abundance in sediments of a groundwater flow-through lake Hydrologic controls on nitrogen cycling processes and functional gene abundance in sediments of a groundwater flow-through lake
The fate and transport of inorganic nitrogen (N) is a critically important issue for human and aquatic ecosystem health because discharging N-contaminated groundwater can foul drinking water and cause algal blooms. Factors controlling N-processing were examined in sediments at three sites with contrasting hydrologic regimes at a lake on Cape Cod, MA. These factors included water...

Stress in mangrove forests: early detection and preemptive rehabilitation are essential for future successful worldwide mangrove forest management Stress in mangrove forests: early detection and preemptive rehabilitation are essential for future successful worldwide mangrove forest management
Mangrove forest rehabilitation should begin much sooner than at the point of catastrophic loss. We describe the need for “mangrove forest heart attack prevention”, and how that might be accomplished in a general sense by embedding plot and remote sensing monitoring within coastal management plans. The major cause of mangrove stress at many sites globally is often linked to reduced tidal...

The physiology of mangrove trees with changing climate The physiology of mangrove trees with changing climate
Mangrove forests grow on saline, periodically flooded soils of the tropical and subtropical coasts. The tree species that comprise the mangrove are halophytes that have suites of traits that confer differing levels of tolerance of salinity, aridity, inundation and extremes of temperature. Here we review how climate change and elevated levels of atmospheric CO2 will influence mangrove...

First documented case of snake fungal disease in a free-ranging wild snake in Louisiana First documented case of snake fungal disease in a free-ranging wild snake in Louisiana
Snake fungal disease (SFD) is a recently documented mycotic disease characterized by scabs or crusty scales, subcutaneous nodules, abnormal molting, cloudiness of the eyes (not associated with molting), and localized thickening or crusting of the skin. SFD has been documented in many species in the Eastern and Midwestern United States within the last decade. SFD has proven lethal in many...

Quantifying fish swimming behavior in response to acute exposure of aqueous copper using computer assisted video and digital image analysis Quantifying fish swimming behavior in response to acute exposure of aqueous copper using computer assisted video and digital image analysis
Behavioral responses of aquatic organisms to environmental contaminants can be precursors of other effects such as survival, growth, or reproduction. However, these responses may be subtle, and measurement can be challenging. Using juvenile white sturgeon (Acipenser transmontanus) with copper exposures, this paper illustrates techniques used for quantifying behavioral responses using...
