Charlene E. Detelich, Una G. Schneck, Alexander G. Hayes, Milan Curcic, Rose Elizabeth Palermo, Andrew D. Ashton, J. Taylor Perron, Juan M. Lora, Jordan Steckloff
2026, JGR Planets (131)
Titan, the only body in the solar system aside from Earth with standing liquids on its surface, has polar hydrocarbon lakes and seas. As Titan’s atmosphere generates light winds, there should be waves on the surface of these lakes and seas, yet, direct wave observations are scant. We introduce and...

Advancing ecosystem recovery with diverse species plantings in tropical forest restoration
Debra A Hamilton, Victorino Molina Rojas, Therese M. Donovan
2026, Forests (17)
Tropical forest restoration has increased in the past decades, with possible advancements given the UN declaration of the “Decade of Ecosystem Restoration”. However, robust assessments to compare ecosystem functions among restored forest stages are essential. We evaluated 13 actively restored forest stands ranging from 3 to 21 years of age...
Factors affecting benthic macroinvertebrate health in the City of Roanoke, Virginia, 2020–2023
Samuel Adam Miller, Marcus F Aguilar, Logan Helsley, Sally Entrekin
2026, Report
Major waterways in the City of Roanoke (City) have failed to meet Virginia’s aquatic life designated use since 1996. Segments of the upper Roanoke River lack healthy benthic macroinvertebrate communities which prompted a total maximum daily load (TMDL) study by the Virginia Department of Environmental Quality (VDEQ) to identify the...

Patterns of recent brook trout invasion in bull trout streams in relation to habitat, source connectivity, biotic resistance, and disturbance
Nicholas S. Voss, Brett J. Bowersox, Daniel C. Nolfi, Michael C. Quist
2026, Canadian Journal of Fisheries and Aquatic Sciences (83) 1-15
Anticipating biological invasions by nonnative species is critical to effective conservation. Nonnative brook trout Salvelinus fontinalis represents one of the most widespread threats to native bull trout Salvelinus confluentus, but the factors allowing or preventing ongoing range expansions are poorly understood. We addressed this uncertainty by resampling 221 survey locations...

Microbes, as the planet’s most abundant and diverse organisms, drive soil functions globally and are vulnerable to environmental stressors triggered by global change. Yet, knowledge regarding the impacts of multiple environmental stressors on their functional profiles as well as the consequences for soil functionality largely remains unknown. Here, we analyze...

As science fields enter the Big Data revolution, open-access repositories are essential for addressing larger-scale questions than are possible for single researchers by making data findable, accessible, interoperable, and reusable (FAIR). Furthermore, transparent data and code are increasingly important for reproducible research, especially for data types that inherently require subjective...

Allison A. Atkinson
2026, Scientific Investigations Report 2026-5017
The U.S. Geological Survey, in cooperation with the City of Lee’s Summit, Missouri, assessed flooding of the East Fork Little Blue River and tributaries for varying precipitation magnitudes and durations, varying antecedent runoff conditions, and projected climate-change conditions. The precipitation scenarios were used to develop a library of flood-inundation...

Elise Penn, Daniel J. Jacob, Daniel M. Bon, Kate Howell, Kelly O’Neill, Tia Scarpelli, Zichong Chen, Robert A. Field, C. Ozgen Karacan, Elfie Roy, Daniel Cusworth
2026, Environmental Science and Technology (60) 14924-14933
Underground coal mines are important global sources of methane, but emission estimates are uncertain. We show that emission estimates for individual mines from aircraft remote-sensing surveys in the United States agree within 40% with direct measurements used for national emission reporting (IPCC Tier 3 estimate). Such direct measurements are unavailable...

2026, Limnology and Oceanography Letters (11)
There are clear advantages for those who openly share their research. Publishing Open Access (OA) articles can increase author visibility (McCabe and Snyder 2014), improve productivity metrics (i.e., more diverse and higher citation rates; Huang et al. 2024; Piwowar et al. 2018), widen collaborative networks (Tai and Robinson 2018), and help secure future funding...
Tringa flavipes (Lesser Yellowlegs) from separate breeding sites subdivides the Prairie Pothole Region in space and time during southbound migration
Rosalyn E. Bathrick, James A. Johnson, Daniel R. Ruthrauff, Katherine Christie, Anna Courtemanche, Callie Gesmundo, Laura Anne McDuffie, Nathan R. Senner
2026, Ornithological Applications
Some staging regions support multiple groups of the same migratory species, each of which may use the region differently. Characterizing the ways, in which separate groups use such regions can therefore help to identify vulnerabilities during this sensitive period of the annual cycle. The Prairie Pothole Region...

Bird migration and energetics simulations incorporating oil spill effects
Benjamin M West, Mark L. Wildhaber, Wayne E. Thogmartin, Michael J. Hooper
2026, Ecological Modelling (519)
Oil spills are well-known for causing acute mortality of birds, but sublethal and delayed impacts are less understood. Focusing on the mallard (Anas platyrhynchos), we used simulation modeling to explore how sublethal oiling may affect avian survival and breeding ground body condition. We used empirically informed migration and energetics simulations...
Monazite and xenotime U-Pb geochronology and thermometry of the Blue Ridge and Inner Piedmont of North Carolina: Implications for the thermal-metamorphic evolution of the southern Appalachian metamorphic “core”
Nicholas Edwin Powell, J. Ryan Thigpen, Brandon M. Spencer, Arthur J. Merschat, David P. Moecher, Calvin A. Mako, Robert D. Hatcher Jr., Harold H. Stowell, Andrew R.C. Kylander-Clark
2026, Tectonics (45)
The southern Appalachian orogen preserves a complex distribution of metamorphism and deformation varying in timing, magnitude, and spatial extent. These complexities give rise to disparate interpretations for southern Appalachian tectonic evolution, which complicates the testing and interpretation of tectonic models in this system. New monazite (Mnz) and...
Simulating past and future refugia for temperate trees in northern Italy
Azzurra Pistone, Paul Henne, Petra Boltshauser-Kaltenrieder, Willy Tinner, Christoph Schworer
2026, Ecography
During the Quaternary, trees responded to the climatic changes of glacial–interglacial cycles with large-scale range shifts. Over cold glacials, temperate tree species contracted their ranges and survived in areas known as refugia. Several studies point to the Euganean Hills (Colli Euganei), in Veneto, northern Italy, as one of the northernmost...

Analyses of eye lens stable isotopes across ontogeny of trophically diverse freshwater salmonids
Glenn T. Schumacher, Ernst B. Peebles, Nathan B. Furey, Michael T. Kinnison, Gregory R. Kronisch, Christina Amy Murphy
2026, PLoS ONE (21)
Ontogenetic niche shifts in fishes are nearly universal but remain poorly understood in many species despite being fundamentally important for the persistence, management, and conservation of fish populations, including those of vulnerable salmonids. Eye lens stable isotope analysis has proven useful in studying ontogeny in some marine species but has...
Multi-proxy thermal history of basin heating during Cordilleran orogenesis in the Magallanes-Austral retroarc foreland basin, Patagonian Andes
Rebecca A. VanderLeest, Julie C. Fosdick, Theresa Maude Schwartz, E.G. Hyland, M. Mastalerz
2026, Basin Research (38)
Resolving thermal histories in sedimentary basins is crucial for interpreting orogenic growth, basin burial, and tectonic processes during Cordilleran orogenesis. In the Magallanes–Austral Basin, Patagonian Andes, we integrate new (U-Th)/He thermochronology, vitrinite reflectance (%Ro), calcite-cement clumped isotope data and thermal history modelling to resolve the origin of the regionally extensive...
Spawning habitat suitability models for Lake Erie cisco (Coregonus artedi) during the historical period of pre- and post-population declines 1877–1957
Katelyn King, Cory O. Brant, Arthur Cooper, Gust Annis, Matthew Herbert, Karen M. Alofs
2026, Journal of Great Lakes Research
Coregonine fishes play a key role in the food webs and fisheries of the Laurentian Great Lakes and are a major focus of basin-wide conservation efforts. In Lake Erie, management goals prioritize rebuilding spawning populations of cisco (Coregonus artedi). However, the historical distribution of cisco spawning habitat and the environmental...
