Evaluating a rapid field assessment system for anticoagulant rodenticide exposure of raptors Evaluating a rapid field assessment system for anticoagulant rodenticide exposure of raptors
Anticoagulant rodenticides (ARs) are commonly used to control rodent pests. However, worldwide, their use is associated with secondary and tertiary poisoning of nontarget species, especially predatory and scavenging birds. No medical device can rapidly test for AR exposure of avian wildlife. Prothrombin time (PT) is a useful biomarker for AR exposure, and multiple commercially available...

Seasonality of biological and physical systems as indicators of climatic variation and change Seasonality of biological and physical systems as indicators of climatic variation and change
Evidence-based responses to climate change by society require operational and sustained information including biophysical indicator systems that provide up-to-date measures of trends and patterns against historical baselines. Two key components linking anthropogenic climate change to impacts on socio-ecological systems are the periodic inter- and intra-annual variations in physical...

COVID-19 pandemic impacts on global inland fisheries COVID-19 pandemic impacts on global inland fisheries
The COVID-19 pandemic has led to environmental recovery in some ecosystems from a global “anthropause,” yet such evidence for natural resources with extraction or production value (e.g., fisheries) is limited. This brief report provides a data-driven global snapshot of expert-perceived impacts of COVID-19 on inland fisheries. We distributed an online survey assessing perceptions of...

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...

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...
