Sprague’s Pipits (Anthus spragueii) occupying high-elevation intermontane valley habitat throughout the breeding season in southwest Montana Sprague’s Pipits (Anthus spragueii) occupying high-elevation intermontane valley habitat throughout the breeding season in southwest Montana
Sprague's Pipit (Anthus spragueii) is an imperiled bird species that breeds in grasslands of the northern Great Plains of North America. While conducting avian surveys in the Centennial Valley, Beaverhead County, southwest Montana, during spring and summer 2023, we detected approximately 10 male Sprague's Pipits performing aerial displays. These represent the first detailed observations...

Genomic and epidemiological investigations reveal chromosomal integration of the acipenserid herpesvirus 3 genome in Lake Sturgeon Acipenser fulvescens Genomic and epidemiological investigations reveal chromosomal integration of the acipenserid herpesvirus 3 genome in Lake Sturgeon Acipenser fulvescens
DNA sequence from a new alloherpesvirus named acipenserid herpesvirus 3 (AciHV-3) was found in sturgeon species that are vulnerable to decline globally. A study was undertaken to develop a better understanding of the virus genome and to develop diagnostic tools to support an epidemiological investigation. A 184,426 bp genome was assembled from PacBio HiFi sequences generated with DNA...

Pediment formation and subsequent erosion in Gale crater: Clues to the climate history of Mars Pediment formation and subsequent erosion in Gale crater: Clues to the climate history of Mars
Evidence of paleo-rivers, fans, deltas, lakes, and channel networks across Mars has prompted much debate about what climate conditions would permit the formation of these surface water derived features. Pediments, gently sloping erosional surfaces of low relief developed in bedrock, have also been identified on Mars. On Earth, these erosional landforms, often thought to be created by...

Multiyear crop residue cover mapping using narrow-band vs. broad-band shortwave infrared satellite imagery Multiyear crop residue cover mapping using narrow-band vs. broad-band shortwave infrared satellite imagery
Crop residue serves an important role in agricultural systems as high levels of fractional crop residue cover (fR) can reduce erosion, preserve soil moisture, and build soil organic carbon. However, the ability to accurately quantify fR at scale has been limited. In this study we produced annual maps of fR for farmland in Maryland, USA using WorldView-3 (WV3) imagery paired with on-farm

Acute Toxicity of 4-hydroxydiphenylamine (4-HDPA) and N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPDQ), transformation products of 6PPD, to early instars of the mayfly, Neocloeon triangulifer Acute Toxicity of 4-hydroxydiphenylamine (4-HDPA) and N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine-quinone (6PPDQ), transformation products of 6PPD, to early instars of the mayfly, Neocloeon triangulifer
Our analysis of water samples collected during a rain event from two urban rivers in the Greater Toronto area, Ontario, Canada, indicated that selected transformation products (TPs) of the tire antioxidant, N-(1,3-dimethylbutyl)-N'-phenyl-p-phenylenediamine (6PPD), including 6PPD-quinone (6PPDQ) and 4-hydroxydiphenylamine (4-HDPA), were present at concentrations >1 µg/L. In acute (96-hr)...

Living with uncertainty: Using multi-model large ensembles to assess emperor penguin extinction risk for the IUCN Red List Living with uncertainty: Using multi-model large ensembles to assess emperor penguin extinction risk for the IUCN Red List
Improved methods for identifying species at risk are needed to strengthen climate change vulnerability assessments, as current estimates indicate that up to one million species face extinction due to environmental changes. Integrating multiple sources of uncertainty enhances the robustness of Red List of Threatened Species assessments, providing a more comprehensive understanding of...

Nature-based solutions could offset coastal squeeze of tidal wetlands from sea-level rise on the U.S. Pacific coast Nature-based solutions could offset coastal squeeze of tidal wetlands from sea-level rise on the U.S. Pacific coast
In this study, we explored the opportunities for tidal wetland landward migration in response to sea-level rise on the Pacific Coast of the United States. By employing a systematic spatial approach, we quantified the available space for wetland migration with sea-level rise across 61 estuarine drainage areas. Although many of the existing tidal wetlands are small patches, our analyses...

Assessing the effect of coral reef restoration location on coastal flood hazard along the San Juan Coastline, Puerto Rico Assessing the effect of coral reef restoration location on coastal flood hazard along the San Juan Coastline, Puerto Rico
Coastal resilience has become a pressing global issue due to the growing vulnerability of coastlines to the effects of climate change. Nature-based solutions have emerged as a promising approach to coastal protection to not only enhance coastal resilience, but also restore critical ecosystems. Coral reef restoration has the potential to provide ecosystem services benefits; however, there...

Looking for Lazarus: Environmental DNA (eDNA) surveillance of the federally threatened Slender Chub (Erimystax cahini) in the Clinch and Powell Rivers Looking for Lazarus: Environmental DNA (eDNA) surveillance of the federally threatened Slender Chub (Erimystax cahini) in the Clinch and Powell Rivers
Erimystax cahni (Slender Chub) is a federally threatened fish native to the Powell, Clinch, and lower Holston rivers of Tennessee and Virginia. No individuals have been captured or reported for over 2 decades. We developed a species-specific environmental DNA (eDNA) assay to survey for its presence throughout its native distribution in new and historical sites. We detected Slender Chub...

Temporal and spatial comparison of coal mine ventilation methane emissions and mitigation quantified using PRISMA satellite data and on-site measurements Temporal and spatial comparison of coal mine ventilation methane emissions and mitigation quantified using PRISMA satellite data and on-site measurements
Emission monitoring at the facility level (bottom-up, BU) is key for accurate reporting of coal mine methane (CMM) emissions. Recent advances in aerial and satellite observations (top-down, TD) indicate that these methods have the potential to support CMM emissions monitoring and reporting of, as well as track the effectiveness of, mitigation actions. That said, studies have shown...

Intraspecific variation in masting across climate gradients is inconsistent with the environmental stress hypothesis Intraspecific variation in masting across climate gradients is inconsistent with the environmental stress hypothesis
Year-to-year variation in seed crop size (i.e., masting) varies strongly among populations of the same species. Understanding what causes this variation is vital, as masting affects the ability of tree species to regenerate and determines the population dynamics of a wide variety of animals. It is commonly thought that environmental stress is a key driver of masting variability. The...

Identifying recruitment sources across trophic levels in a large river food web Identifying recruitment sources across trophic levels in a large river food web
Assemblages are connected through the movement of physical and biological resources including recruits. Identifying recruitment sources for predators and their prey could help us understand how assemblages use connectivity across multiple trophic levels and whether predator and prey recruitment is coupled. Recruitment sources of organisms across multiple trophic levels can be quantified...
