Predicting daily river chlorophyll concentrations at a continental scale
Philip Savoy, Judson Harvey
2023, Water Resources Research (59)
Eutrophication is one of the largest threats to aquatic ecosystems and chlorophyll a measurements are relevant indicators of trophic state and algal abundance. Many studies have modeled chlorophyll a in rivers but model development and testing has largely occurred at individual sites which hampers creating generalized models capable of making broad-scale...
Snag dynamics and surface fuel loads in the Sierra Nevada: Predicting the impact of the 2012–2016 drought
Hudson Northrop, Jodi N. Axelson, Adrian Das, Nathan L. Stephenson, Emilio Vilanova, Scott L. Stephens, John J. Battles
2023, Forest Ecology and Management (551)
Forest die-backs linked to extreme droughts are expected to increase as the climate dries and warms. An example is the 2012-2016 hotter drought in California that induced widespread tree mortality in the Sierra Nevada, California. The sudden increase in snags (i.e., standing dead trees) raised immediate concerns about their impact...
Marginal value analysis reveals shifting importance of migration habitat for waterfowl under a changing climate
Ryan C. Burner, Benjamin Donald Golas, Kevin J. Aagaard, Eric V. Lonsdorf, Wayne E. Thogmartin
2023, Ecology and Evolution (13)
Migratory waterfowl are an important resource for consumptive and non-consumptive users alike and provide tremendous economic value in North America. These birds rely on a complex matrix of public and private land for forage and roosting during migration and wintering periods, and substantial conservation...
Creating oriented and precisely sectioned mineral mounts for in situ chemical analyses—An example using olivine for diffusion chronometry studies
Kendra J. Lynn, Liliana G. Desmither
2023, Techniques and Methods 5-D5
Diffusion chronometry is now a widely applied methodology for determining the rates and timescales of geologic processes from the chemical zoning observed in minerals. Despite the popularity of the method, several challenges still remain during its application, including: (1) the random sectioning of minerals either in thin sections or grain...
Effects of landcover on mesocarnivore density and detection rate along an urban to rural gradient
Leah McTigue, Brett Alexander DeGregorio
2023, Global Ecology and Conservation (48)
Human development has major implications for wildlife populations. Urban-exploiter species can benefit from human subsidized resources, whereas urban-avoider species can vanish from wildlife communities in highly developed areas. Therefore, understanding how the density of different species varies in response to landcover changes associated with human development can provide important insight...
Shifted sediment-transport regimes by climate change and amplified hydrological variability in cryosphere-fed rivers
Tinghu Zhang, Dongfeng Li, Amy E. East, Albert J. Kettner, James L. Best, Jinren Ni, Xixi Lu
2023, Science Advances (9)
Climate change affects cryosphere-fed rivers and alters seasonal sediment dynamics, affecting cyclical fluvial material supply and year-round water-food-energy provisions to downstream communities. Here, we demonstrate seasonal sediment-transport regime shifts from the 1960s to 2000s in four cryosphere-fed rivers characterized by glacial, nival, pluvial, and mixed regimes, respectively. Spring sees a...

Paul Krushelnycky, Lucas Berio Fortini, Jeffrey Mallinson, Jesse Felts
2023, Scientific Reports (13)
Accurate estimates of current and future habitat suitability are needed for species that may require assistance in tracking a shifting climate. Standard species distribution models (SDMs) based on occurrence data are the most common approach for evaluating climatic suitability, but these may suffer from inaccuracies stemming...

2023, Geochemistry, Geophysics, Geosystems (24)
Alaska contains over 130 volcanoes and volcanic fields that have been active within the last 2 million years. Of these, roughly 90 have erupted during the Holocene, with many characterized by at least one large explosive eruption. These large tephra-producing eruptions (LTPEs) generate orders of magnitude more...
