Yellowstone grizzly bear investigations — Annual report of the Interagency Grizzly Bear Study Team 2017 Yellowstone grizzly bear investigations — Annual report of the Interagency Grizzly Bear Study Team 2017
This Annual Report summarizes results of grizzly bear (Ursus arctos) monitoring and research conducted in the Greater Yellowstone Ecosystem (GYE) by the Interagency Grizzly Bear Study Team (IGBST) during 2017. This report also contains a summary of grizzly bear management actions to address conflict situations. Annual reports of the IGBST summarize annual data collection. Because...
Data quality from a community-based, water-quality monitoring project in the Yukon River basin Data quality from a community-based, water-quality monitoring project in the Yukon River basin
This paper examines the quality of data collected by the Indigenous Observation Network, a community-based water-quality project in the Yukon River Basin of Alaska and Canada. The Indigenous Observation Network relies on community technicians to collect surface-water samples from as many as fifty locations to achieve their goals of monitoring the quality of the Yukon River and major...

What specific costs and risks do we face from climate change? What specific costs and risks do we face from climate change?
A new U.S. government report finds that climate change is already increasing risks to health, the economy, and ecosystems across the United States. These risks are expected to grow in the coming decades.

Range position and climate sensitivity: The structure of among-population demographic responses to climatic variation Range position and climate sensitivity: The structure of among-population demographic responses to climatic variation
Species’ distributions will respond to climate change based on the relationship between local demographic processes and climate and how this relationship varies based on range position. A rarely tested demographic prediction is that populations at the extremes of a species’ climate envelope (e.g., populations in areas with the highest mean annual temperature) will be most sensitive to...

Acute and chronic toxicity of aluminum to a unionid mussel (Lampsilis siliquoidea) and an amphipod (Hyalella azteca) in water‐only exposures Acute and chronic toxicity of aluminum to a unionid mussel (Lampsilis siliquoidea) and an amphipod (Hyalella azteca) in water‐only exposures
The US Environmental Protection Agency (USEPA) is reviewing the protectiveness of the national ambient water quality criteria (WQC) for aluminum (Al) and compiling a toxicity data set to update the WQC. Freshwater mussels are one of the most imperiled groups of animals in the world, but little is known about their sensitivity to Al. The objective of the present study was to evaluate...

Demography of the Pacific walrus (Odobenus rosmarus divergens) in a changing Arctic Demography of the Pacific walrus (Odobenus rosmarus divergens) in a changing Arctic
The Pacific walrus (Odobenus rosmarus divergens) is a candidate to be listed as an endangered species under United States law, in part, because of climate change‐related concerns. While the population was known to be declining in the 1980s and 1990s, its recent status has not been determined. We developed Bayesian models of walrus population dynamics to assess the population by...

Rule reversal: Ecogeographical patterns of body size variation in the common treeshrew (Mammalia, Scandentia) Rule reversal: Ecogeographical patterns of body size variation in the common treeshrew (Mammalia, Scandentia)
There are a number of ecogeographical “rules” that describe patterns of geographical variation among organisms. The island rule predicts that populations of larger mammals on islands evolve smaller mean body size than their mainland counterparts, whereas smaller‐bodied mammals evolve larger size. Bergmann's rule predicts that populations of a species in colder climates (generally at...

Effects of ocean acidification on salinity tolerance and seawater growth of Atlantic salmon Salmo salar smolts Effects of ocean acidification on salinity tolerance and seawater growth of Atlantic salmon Salmo salar smolts
Human activity has resulted in increasing atmospheric carbon dioxide (CO2), which will result in reduced pH and higher levels of CO2 in the ocean, a process known as ocean acidification. Understanding the effects of ocean acidification (OA) on fishes will be important to predicting and mitigating its consequences. Anadromous species such as salmonids may be especially at risk because of...

Global conservation status of turtles and tortoises (order Testudines) Global conservation status of turtles and tortoises (order Testudines)
We present a review and analysis of the conservation status and International Union for Conservation of Nature (IUCN) threat categories of all 360 currently recognized species of extant and recently extinct turtles and tortoises (Order Testudines). Our analysis is based on the 2018 IUCN Red List status of 251 listed species, augmented by provisional Red List assessments by the IUCN...

Southeast Southeast
The Southeast includes vast expanses of coastal and inland low-lying areas, the southern portion of the Appalachian Mountains, numerous high-growth metropolitan areas, and large rural expanses. These beaches and bayous, fields and forests, and cities and small towns are all at risk from a changing climate. While some climate change impacts, such as sea level rise and extreme downpours...
