Highly pathogenic avian influenza viruses (HPAIV) persistently threaten wild waterfowl, domestic poultry, and public health. The East Asian–Australasian Flyway plays a crucial role in HPAIV dynamics due to its large populations of migratory waterfowl and poultry. Over recent decades, this flyway has undergone substantial landscape changes, including both losses and...
Integrating hunter dynamics and waterfowl dynamics to inform harvest management
Richard Eugene Waggaman Berl, Patrick K. Devers, G. Scott Boomer, Michael Runge
2025, Journal of Wildlife Management
The successful conservation and management of North American waterfowl relies upon an adaptive harvest management framework that accounts for changes in the system state and critical uncertainties related to the dynamics of waterfowl populations and habitats. Increasing recognition of the importance of the human dimensions of the harvest process, particularly...
Economic costs of invasive carps in the United States: Case study and management implications
Ellie Brown, Joseph W. Snapp, Christopher Huber, James Caudill, Peter E. Grigelis
2025, Biological Invasions (27)
Biological invasions can have far-reaching impacts and incur enormous monetary costs. Economic considerations play an important role in management decision-making. We used the invasion of U.S. waterways by silver (Hypophthalmichthys molitrix) and bighead (H. nobilis) carp as a case study of the costs of aquatic invasive species. Although these carps...

2025, Journal of Environmental Management (392)
Climate change is transforming ecosystems globally. The Resist-Accept-Direct (RAD) framework has gained traction within many natural resource management institutions to help consider the decision space in response to this transformation. Because RAD helps manage for directional change, RAD choices entail considering which RAD pathway to implement and for how long....
Relationships between water quality, stream metabolism, and water stargrass growth in the lower Yakima River, 2018 to 2020
Rich W. Sheibley, Marcella Appel, James R. Foreman
2025, Preprint
Since the early 2000s, water clarity on the lower Yakima River has improved. Changes in best management practices combined with a total maximum daily load for suspended sediment led to these improved conditions. As water clarity improved, so did conditions for aquatic plants; the clearer the water, the better the...

We evaluated measurable attributes describing the current and future distribution of Cervus elaphus canadensis (elk) across a region surrounding Jackson, Wyoming, for five feedground management alternatives proposed by the U.S. Fish and Wildlife Service as a revision to the 2007 “Bison and Elk Management Plan” of the National Elk Refuge....
Assessing American eel (Anguilla rostrata) distribution in a heavily dammed watershed using eDNA : The Penobscot River watershed, Maine, USA
Shawn Snyder, Cody Dillingham, Lara S. Katz, Michael T. Kinnison, Joseph D. Zydlewski
2025, River Research and Applications (41) 1970-1981
Catadromous American eel ( Anguilla rostrata ) are native to Maine's Penobscot River watershed and historically have migrated through many of its tributaries prior to extensive damming. Recent restoration efforts, including dam removals, have improved connectivity in the lower reaches of the Penobscot River. Characterizing the extent of the American eel's distribution...
Bridging theory and practice to inform seed selection for restoration
Laura Cecilia Shriver, Samuel E. Jordan, Robert Massatti, Seth Munson
2025, Restoration Ecology (33)
Introduction Land managers often face the critical decision of what plant materials to select for ecological restoration. Selection depends on factors that span ecological conditions and human interventions in the restoration process, which can strongly influence the recovery of a degraded ecosystem. Objectives To improve the seed selection process, we...
Low genetic diversity in populations of a clonal invasive plant limits sexual reproduction
Ian S. Pearse, Zoe Becker, Paul J. Ode, John F. Gaskin, Natalie West
2025, American Journal of Botany (112)
PremiseClonality, a form of asexual reproduction and spread, is common among invasive plants, though sexual reproduction via seeds is often still important for their long-range dispersal. In small populations, clonality has been hypothesized to interfere with sexual reproduction by limiting outcrossing opportunities of a plant.MethodsWe developed a structural equation model...
Magnitude, depth and methodological variations of spectral stress drop within the SCEC/USGS Community Stress Drop Validation Study using the 2019 Ridgecrest Earthquake Sequence
Rachel E. Abercrombie, Annemarie S. Baltay Sundstrom
2025, Bulletin of the Seismological Society of America (115) 2741-2768
We present the first ensemble analysis of the 56 different sets of results submitted to the ongoing Community Stress Drop Validation Study using the 2019 Ridgecrest, California, earthquake sequence. Different assumptions and methods result in different estimation of the source contribution to recorded seismograms, and hence to the source parameters...
Some of these are not like the others: Relative thermal sensitivity among anuran species of the Southeast United States
Traci P. Dubose, Chloe E. Moore, Vincent R. Farallo, Abigail Benson, William A. Hopkins, Samuel Silknetter, Meryl C. Mims
2025, Ecosphere (16)
Estimating how close a species is to its upper thermal limits (i.e., warming tolerance, a thermal sensitivity index) and how that proximity changes across space enables spatially explicit identification of species with increased extinction risk as temperatures increase. Yet, thermal sensitivity is often difficult to calculate because it is the...

Increased soil greenhouse gas emissions from the combined use of cover crops and no‐tillage in producer‐ managed fields
Yu Peng, Pierre-Andre Jacinthe, Edward G. Dobrowolski, Lixin Wang
2025, Earth's Future (13)
Cover crop adoption offers multiple benefits and climate mitigation potential for agroecosystems, but is still an underutilized conservation practice. Recently, the combined use of cover cropping plus no-tillage (CCNT) has been increasingly promoted to achieve its synergistic effectiveness. Yet, how this combined practice affects soil greenhouse gas (GHG) emission remains...
Multi-scale habitat characteristics influence Paleback Darter occupancy and detection probability
Maxwell L. Hartman, Katie M. Morris, Jonathan J. Spurgeon, Steve E. Lochmann
2025, Transactions of the American Fisheries Society (154) 585-594
ObjectiveThe limited distribution of the Paleback Darter Etheostoma pallididorsum, which is often associated with dynamic headwater streams, makes the species vulnerable to changes in its environment in west-central Arkansas. A detailed understanding of habitat characteristics that support the species at multiple spatial scales is limited. This project assessed the relative influences...
Perceptions of climate vulnerability for subsistence inland fisheries in the United States
Caitlin Montano, Abigail Lynch, Ian Harrison, Denielle M. Perry
2025, Fisheries
Globally, inland fisheries are important sources of food, particularly for some communities where fishing is socially or culturally important or where local community economics require families to find cheap sources of food. However, little information specific to subsistence inland fisheries and their dependent communities is available for the United States,...
Alternating movement strategies of a tropical raptor
Eben H. Paxton, Kristina L. Paxton
2025, Scientific Reports (15)
The majority of raptor species reside in the tropics, yet very little is known about their movement ecology. However, quantifying movement behavior can provide otherwise elusive information on resource needs, habitat selection, and ecological constraints, which is important for understanding ecological patterns and the management of species of conservation concern....
