2024, PLoS ONE (19)
With the decline of bee populations worldwide, studies determining current wild bee distributions and diversity are increasingly important. Wild bee identification is often completed by experienced taxonomists or by genetic analysis. The current study was designed to compare two methods of identification including: (1) morphological identification...
Nontarget effects of pre-emergent herbicides and a bioherbicide on soil resources, processes, and communities
Brynne E. Lazarus, Matthew J. Germino, Marie-Anne de Graaff
2024, Restoration Ecology (32)
Community-type conversions, such as replacement of perennials by exotic annual grasses in semiarid desert communities, are occurring due to plant invasions that often create positive plant–soil feedbacks, which favor invaders and make restoration of native perennials difficult. Exotic annual grass control measures, such as...
Climate-driven increases in stream metal concentrations in mineralized watersheds throughout the Colorado Rocky Mountains, USA
Andrew H. Manning, Tanya N. Petach, Robert L. Runkel, Diane M. McKnight
2024, Water Resources Research (60)
Increasing stream metal concentrations apparently caused by climate warming have been reported for a small number of mountain watersheds containing hydrothermally altered bedrock with abundant sulfide minerals (mineralized watersheds). Such increases are concerning and could negatively impact downstream ecosystem health, water resources, and mine-site remediation efforts. However,...

Factors associated with Paddlefish (Polyodon spathula) restoration success in Oklahoma
Ryan A. Gary, James M. Long, Brian T. Eachus, Andrew R. Dzialowski, Jason D. Schooley
2024, Fisheries Management and Ecology (31)
The Paddlefish (Polyodon spathula) has been extirpated from portions of its native range due to anthropogenic habitat degradation and fragmentation, most notably the impoundment of rivers. To mitigate some of these losses in Oklahoma, Paddlefish have been stocked into reservoirs throughout the state, with variable success in establishing self-sustaining populations. Two...

Maintaining the integrity and health of aquatic ecosystems is critical to sustaining the many valued services that they provide society. Unfortunately, achieving this goal has proven challenging in most of the world's large ecosystems owing to rampant environmental change caused by human-driven stress, including accelerating climate change, pollution of waterways,...
Fishes move to transient local refuges, not persistent landscape refuges during river drying experiment
Thomas P Archdeacon, Eric J. Gonzales, Charles B. Yackulic
2024, Freshwater Biology (69) 792-808
Anthropogenically driven flow intermittency is increasing in freshwater streams, with important implications for the management and conservation of aquatic ecosystems. Because most freshwater fishes are mobile, they are expected to emigrate from intermittent reaches, but this may not be true in streams transitioning from perennial to intermittent. Here, we...

Melanie M Esch, Catherine S. Jarnevich, Nuno Simoes, Timothy R McClanahan, Alastair R Harborne
2024, Coral Reefs (43) 641-653
Predicting the potential distribution of a non-native species can assist management efforts to mitigate impacts on recipient ecosystems. However, such predictions are lacking for marine species, such as the non-native regal demoiselle, Neopomacentrus cyanomos, that is currently expanding its distribution in the western Atlantic. We used correlative...
Methane clumped isotopologue variability from ebullition in a mid-latitude lake
Ellen Jennifer Lalk, Amber Velez, Shuhei Ono
2024, ACS Earth and Space Chemistry (8) 689-701
Methane is a greenhouse gas and is an important component of carbon cycling in freshwater environments. Isotope ratios of methane (13C/12C and D/H) are used extensively as tracers to identify methane sources. Recent advances in the measurement of clumped methane isotopologues (13CH3D, 12CH2D2) offer new opportunities to constrain sources and sinks...

Katherine M. Scharer, Devin McPhillips, Jenifer Amy Leidelmeijer, Matthew Kirby
2024, Earth Surface Processes and Landforms (49) 2309-2582
Radiocarbon dates of sedimentary deposits include the elapsed time between formation of the organic material and deposition at the sample site, known as the inherited age. Long inherited ages reduce the accuracy of estimates of the timing of depositional events used to infer paleoclimate change, fire histories, and paleoearthquake...

Eight springs and seeps at Fort Irwin National Training Center were described and categorized by their general characteristics, discharge, geophysical properties, and water quality between 2015 and 2017. The data collected establish a modern (2017) baseline of hydrologic conditions at the springs. Two types of springs were identified: (1) precipitation-fed...
Post-wildfire debris flows
Joseph Gartner, Jason W. Kean, Francis K. Rengers, Scott W. McCoy, Nina S. Oakley, Gary J. Sheridan
2024, Book chapter, Advances in Debris-flow Science and Practice
Post-wildfire debris flows pose severe hazards to communities and infrastructure near and within recently burned mountainous terrain. Intense heat of wildfires changes the runoff characteristics of a watershed by combusting the vegetative canopy, litter, and duff, introducing ash into the soil and creating water repellant soils. Following wildfire, rainfall on...
Lahars: Origins, behavior and hazards
James W. Vallance
Matthias Jakob, Scott McDougall, Paul Santi, editor(s)
2024, Book chapter, Advances in debris-flow science and practice
Volcanic debris flows that originate at potentially active volcanoes are called lahars. Lahars are like debris flows in non-volcanic terrain but can most notably differ in origin and size. Primary lahars occur during eruptions and may have novel origins such as turbulent mixing of hot rock moving across ice- and...
