Dispersal and survival of sea lamprey in Lake Erie and connected waterways
Sean Alois Lewandoski, Christopher Holbrook
2025, Canadian Journal of Fisheries and Aquatic Sciences (82) 1-13
Invasive sea lamprey inhabiting the North American Laurentian Great Lakes are the target of the world’s longest running vertebrate invasive species control program. However, metapopulation dynamics comprising survival and dispersal during the sea lampreys’ lake-resident life stages are poorly understood. We applied acoustic telemetry and continuous-time multistate capture-recapture modeling to...

Erica M. Gallerani, Richard J. Camp, Paul C. Banko, Austin Madson, Chunyu Dong, Lucas Fortini, Zhimin Ma, Thomas W. Gillespie
2025, Global Ecology and Conservation (62)
The Palila (Loxioides bailleui), the last member of the once speciose finch-billed Hawaiian honeycreeper clade (Drepanidinae) in the main Hawaiian Islands, faces critical conservation challenges as an endangered species. Understanding the drivers of its decline is essential for effective management. We used additive decomposition models to examine temporal trends in...

Wetland ecohydrology
Mark D. Dixon, W. Carter Johnson, Beth Middleton
Alan Dixon, Ian Maddock, editor(s)
2025, Book chapter, Routledge handbook of wetlands
Ecohydrology emphasizes the interactions between ecological and hydrological patterns and processes in wetlands. Given that wetlands are fundamentally defined by prolonged saturation or flooding of land, an ecohydrological perspective is implicit in wetland ecology. In this review, we provide examples of how variation in hydrologic processes in space and time...
Sulfide stress tolerance as a controller of methane production in temperate wetlands
Emily Bechtold, Jared B. Ellenbogen, Danhui Xin, Marcia Pacheco, Brandy M. Toner, Yu-Ping Chin, William A. Arnold, Sheel Bansal, Michael J. Wilkins
2025, International Society of Microbial Ecology Journal (19)
Wetlands are a major source of methane emissions and contribute to the observed increase in atmospheric methane over the last 20 years. Methane production in wetlands is the final step of carbon decomposition performed by anaerobic archaea. Although hydrogen/carbon dioxide and acetate are the substrates most often attributed to methanogenesis, other...
Hiding in plain sight: Genomic characterization of a novel nackednavirus and evidence of diverse adomaviruses in a hyperpigmented lesion of a largemouth bass (Micropterus salmoides)
Clayton D. Raines, John Odenkirk, Michael Isel, Patricia Mazik, Morgan Alexandra Biggs, Luke Iwanowicz
2025, Viruses (17)
Largemouth bass (LMB; Micropterus nigricans) are popular both as a sportfish and an aquaculture species. At present, six described viruses are associated with LMB, of which two are typically considered in cases of LMB mortality events. Advances in discovery and diagnostic capabilities using next-generation sequencing have augmented surveillance efforts and...
A synthesis engine for constructing geologic maps of the United States
Samuel Johnstone, Joseph P. Colgan, Warren P. Roe
2025, Data Report 1210
The geologic history of the United States is cataloged in thousands of geologic maps produced during many decades. However, the disparate nature of these individual maps makes it challenging to assess resources, research geologic histories, or characterize natural hazards holistically across the Nation. The U.S. House of Representatives 2020 appropriations...

David S. Pilliod, Michaela Ray Grossklaus, Stacie A. Kageyama, Cale Nordmeyer, Jerry Reinisch, Erik Runquist, Stephen Frank Spear
2025, Global Ecology and Conservation (62)
The development of environmental DNA (eDNA) methods for terrestrial arthropods could be transformative for the difficult task of assessing the status of species of conservation concern. The primary goal of this study was to investigate the efficacy of detecting the Dakota skipper (Hesperia dacotae) from its DNA left behind on...

Benjamin J. Drenth, Amanda Souders, William F. Cannon, Jay Michael Thompson
2025, Canadian Journal of Earth Sciences (62) 1459-1473
The Great Lakes tectonic zone (GLTZ) forms the boundary between the Wawa–Abitibi and Minnesota River Valley subprovinces within the Archean Superior Province. The GLTZ is concealed for all of its 1100 km length, except for a segment in the central Upper Peninsula of Michigan. There, it is exposed as a northwest-striking...
Desert ecosystems shape diversification in glossy snakes (genus Arizona) requiring a re-alignment of evolutionary and conservation units
Dustin Wood, Jonathan Q. Richmond, Michael F. Westphal, Bradford D. Hollingsworth, Robert D. Fisher, Amy G. Vandergast
2025, Molecular Phylogenetics and Evolution (213)
Subspecies are often targets for conservation, yet many lack the genetic data necessary to validate their status as distinctive evolutionary lineages. In 2016, conservationists faced this issue when designating the California glossy snake, Arizona elegans occidentalis, as a Species of Special Concern in California, a decision prompted by population declines and...

2025, Sustainability (17)
Individuals are routinely exposed to traffic-related air pollution on their commutes, which has significant health impacts. Mitigating exposure to traffic-related pollution is a key urban sustainability concern. In Denver, Colorado, low-income Americans are more likely to rely on buses and spend time waiting at bus stops. Evaluating the contribution of...

2025, Atmospheric Environment X (27)
Characterizing traffic-related air pollutants (TRAPs), which significantly impact health, and greenhouse gases (GHGs) can be challenging in urban environments. Mobile monitoring has the potential to capture the spatial distribution of these pollutants. We present results from a campaign using the Denver Mobile Monitoring Laboratory (DMML) in the summer of 2023...

2025, Open-File Report 2025-1043
To support ecosystem mapping and accounting applications, we aligned the 2015 U.S. Geological Survey/Esri/The Nature Conservancy-World Terrestrial Ecosystems (WTEs) with the International Union for Conservation of Nature Global Ecosystem Typology (GET) framework. This process, known as “crosswalking,” enabled the development of a global map of GET level 3 Ecosystem Functional...
Perceptions and management of chronic wasting disease in Washington State: A survey of cervid hunters
Megan Callahan, Melia DeVivo, Brian Kertson, Hunter Westacott, Michael C Mcinturff
2025, Report
Chronic wasting disease (CWD) is a fatal neurological disease caused by a misfolded protein, or prion, and is found in cervids (e.g., deer, elk, moose). It represents a serious threat to cervid populations and is one of the most important ungulate management issues facing state wildlife management agencies. Issues associated...
Monitoring cyanobacteria temporal trends in a hypereutrophic lake using remote sensing: From multispectral to hyperspectral
Samantha L. Sharp, Alicia Cortes, Alexander L. Forrest, Carl J. Legleiter, Liane S. Guild, Yufang Jin, S. Geoffrey Schladow
2025, Remote Sensing Applications: Society and Environment (39)
Cyanobacterial harmful algal blooms (cyanoHABs) and associated cyanotoxins are a concern for inland waters. Due to the extensive spatial coverage and frequent availability of satellite images, multispectral remote sensing tools demonstrate utility for monitoring these blooms. The next frontier for remote sensing of cyanoHABs in inland waters is hyperspectral data....

The role of fire on Earth
Juli G. Pausas, Jon Keeley, William J. Bond
2025, BioScience (75) 1028-1041
Fire is a defining feature of our biosphere, having appeared when the first plants colonized the land, and it continues to occur across the planet at different frequencies and intensities. Fire has been and remains as an evolutionary force in many plant and animal lineages and contributes to explaining the...
Contrasting long-term trends in channel width and shoreline complexity
Elizabeth Rachaelann Skaggs, Jonathan M. Friedman, Christopher Holmquist-Johnson
2025, Geomorphology (489)
Drought and reservoir management in the Colorado River Watershed have decreased peak flows and sediment loads reducing the ability of rivers to change their channels. Multiple studies have documented the resulting decrease in channel width, but less attention has been paid to long-term trends in shoreline complexity, including the number...
