Transport and speciation of uranium in groundwater-surface water systems impacted by legacy milling operations Transport and speciation of uranium in groundwater-surface water systems impacted by legacy milling operations
Growing worldwide concern over uranium contamination of groundwater resources has placed an emphasis on understanding uranium transport dynamics and potential toxicity in groundwater-surface water systems. In this study, we utilized novel in-situ sampling methods to establish the location and magnitude of contaminated groundwater entry into a receiving surface water environment, and to...

Ecological and social dimensions of sloth bear conservation in Sri Lanka Ecological and social dimensions of sloth bear conservation in Sri Lanka
Balancing the needs of humans and wildlife in Sri Lanka presents enormous socioeconomic and conservation challenges. Sloth bears are legally protected, but attacks on humans generate intense fear, which increases the potential for human-caused bear mortality and local extirpation of bears. In this chapter, what is known about the ecology and human dimensions of the sloth bear in a...

Migration routes and population status of the Brent Goose Branta bernicla nigricans wintering in East Asia Migration routes and population status of the Brent Goose Branta bernicla nigricans wintering in East Asia
Of the world’s Brent Goose Branta bernicla populations, the migration routes and winter distribution of the East Asian population of Brent Geese B. b. nigricans are the least well known. We therefore marked Brent Geese at their primary pre-migratory staging area in Notsuke Bay, Hokkaido, Japan to describe their migration between breeding and wintering areas in East Asia. Additionally...

Wetlands in agricultural landscapes—Significant findings and recent advances from CEAP-Wetlands Wetlands in agricultural landscapes—Significant findings and recent advances from CEAP-Wetlands
The Wetlands Component of the USDA's Conservation Effects Assessment Project (CEAP-Wetlands) is a multi-agency effort advancing science related to quantifying and interpreting effects and effectiveness of conservation practices and programs on ecosystem services provided by wetlands in agricultural landscapes. This special section originated from a symposium held at the 73rd Soil and...

Upper Mississippi River system weighted wind fetch analysis (1989, 2000, 2010/2011) Upper Mississippi River system weighted wind fetch analysis (1989, 2000, 2010/2011)
Wind fetch is defined as the unobstructed distance that wind can travel over water in a constant direction. Fetches are limited by landforms surrounding the body of water. Fetch is an important characteristic of open water because longer fetches can result in larger wind-generated waves. The larger waves, in turn, can increase shoreline erosion and sediment resuspension (Rohweder and...

Using hair cortisol to assess physiological stress in Alaska polar bears Using hair cortisol to assess physiological stress in Alaska polar bears
The concentration of cortisol in hair (HCC) of polar bears (Ursus maritimus) may provide a retrospective view of physiological stress they experience and a link to their response to environmental change. To understand this relationship, we assayed HCC from polar bears captured in the Alaska Beaufort, Bering and Chukchi seas during 1983–1989 and 2004–2016. Cortisol accumulated in hair...
