Re-examination of the 1958 Huslia earthquake sequence and regional tectonics of the northwestern Koyukuk Basin, Alaska Re-examination of the 1958 Huslia earthquake sequence and regional tectonics of the northwestern Koyukuk Basin, Alaska
In 1958 a Mw 6.8 (MS = 7.3) mainshock and two Mw ∼ 5.9 aftershocks occurred near the village of Huslia in the remote Koyukuk Basin of northern interior Alaska, with no surface faulting recognized afterward. This region lies in a transitional zone between compressional tectonics associated with the collision of the Pacific and Yakutat plates with North America and the extrusion of western...

Two-stage approach to automatic detection with machine learning for improved surveillance of the invasive Cuban treefrog Two-stage approach to automatic detection with machine learning for improved surveillance of the invasive Cuban treefrog
The Cuban treefrog (Osteopilus septentrionalis), as an invasive species in the southern United States, presents a need for effective surveillance. Automated detection expedites processing of audio data for large-scale surveillance and monitoring programs. However, current available methods commonly used for anuran species have not been sufficient to detect Cuban treefrogs. Here, we...

Detecting bumble bees in the wild using environmental DNA: Development and validation of a qPCR assay for the endangered Franklin’s bumble bee (Bombus franklini) Detecting bumble bees in the wild using environmental DNA: Development and validation of a qPCR assay for the endangered Franklin’s bumble bee (Bombus franklini)
Environmental DNA (eDNA) sampling is a noninvasive alternative to conventional methods of surveying insects that may be particularly useful for detecting pollinators. We developed a quantitative polymerase chain reaction (qPCR) assay to detect the DNA of Franklin’s bumble bee (Bombus franklini) from flower samples and conducted an initial test of the assay using samples collected within...

Initial condition uncertainty exerts a large and persistent influence on model simulations of ecosystem carbon dynamics in California Initial condition uncertainty exerts a large and persistent influence on model simulations of ecosystem carbon dynamics in California
Uncertainties in terrestrial ecosystem models limit their predictive power. Efforts to reduce projection error have rarely focused on constraining uncertainty in the initial state of the ecosystem, however, despite evidence that matching model initial conditions to real-world observations reduces overall model bias. Here we use an integrated land change and carbon gain-loss model to...

Channel morphology and large wood control postfire debris-flow erosion and deposition Channel morphology and large wood control postfire debris-flow erosion and deposition
Runoff-generated debris flows are a known response to wildfire, and accurately predicting the volume of these debris flows is important for estimating the magnitude of downstream hazards. Prior data collection efforts have focused on debris-flow volume measurements at catchment outlets, but few studies have considered how erosion and deposition modulate the volume of sediment arriving at...

The Climate Hazards Center Infrared Precipitation with Stations, version 3 The Climate Hazards Center Infrared Precipitation with Stations, version 3
The Climate Hazards Center Infrared Precipitation with Stations (CHIRPS) data stream combines: (1) a high-resolution climatology, (2) thermal infrared (TIR) geostationary satellite observations, and (3) station observations. In the past, CHIRPS version 2 (CHIRPS2) has proven to be valuable for drought monitoring, hydrologic modeling, scientific studies and agricultural decision making...

Phytoplankton responses to experimental nitrogen and phosphorus loading in the eutrophic and colored Caloosahatchee River, Florida Phytoplankton responses to experimental nitrogen and phosphorus loading in the eutrophic and colored Caloosahatchee River, Florida
The Caloosahatchee River, located in southwest Florida, is a eutrophic and colored river that flows from Lake Okeechobee westward into its estuary and the Gulf of America. Cyanobacterial harmful algal blooms (HABs) are a documented problem along this freshwater-to-marine waterway where nutrient enrichment has been identified as a key factor in bloom occurrence but has not been...

Occurrence of cyanobacteria and associated cyanotoxins in the Raritan Basin Water Supply Complex, New Jersey, August 2020 to August 2021 Occurrence of cyanobacteria and associated cyanotoxins in the Raritan Basin Water Supply Complex, New Jersey, August 2020 to August 2021
Harmful algal blooms, particularly cyanobacteria harmful algal blooms (cyanoHABs), have emerged as a substantial global concern because of their detrimental effects on water quality and aquatic ecosystem health. CyanoHABs can produce cyanotoxins, which pose serious health risks to humans and wildlife, such as liver failure and respiratory distress. This is particularly concerning for...

The WOAH global wildlife health collaborating centre network (WOAH-WildNet): A coordinated and transformative approach to global wildlife health challenges The WOAH global wildlife health collaborating centre network (WOAH-WildNet): A coordinated and transformative approach to global wildlife health challenges
Wildlife health is integral to functioning, complex ecosystems [1], directly and indirectly influencing the health of people, animals, plants, and the environment [2–4]. Healthy wildlife populations are essential for ecosystem services and are at the heart of the One Health approach [3,4], which aims to sustainably balance and optimize the health of people, animals, and ecosystems...

Quality and quantity of terrestrial landscape connectivity in the US Great Lakes Coastal Zone Quality and quantity of terrestrial landscape connectivity in the US Great Lakes Coastal Zone
Context The Great Lakes Coastal Zone (GLCZ), the world’s longest continuous freshwater coastline, consists of interspersed natural and developed landcover and is inhabited by millions of people. Anthropogenic change fragments the GLCZ, decreasing landscape connectivity.Objectives We evaluated functional landscape connectivity of the U.S. GLCZ, assessing regional connectivity, protected...
