Megan Schall, Geoff Smith, Vicki S. Blazer, Heather L. Walsh, Tyler Wagner
2025, Journal of Fish Diseases (48)
Hyperpigmented melanistic lesions (HPMLs) are a visual anomaly documented on the skin of smallmouth bass Micropterus dolomieu in the Susquehanna River Basin, Pennsylvania and in numerous other geographical locations. Currently, there is a lack of information on environmental and fish characteristics that may influence the prevalence of HPMLs associated with a recently...
Comparative behavioral responses of grass carp (Ctenopharyngodon idella), bighead carp (Hypophthalmichthys nobilis), and silver carp (H. molitrix) to free amino acids in water
Mark L. Wildhaber, Zachary D Beaman, Karlie K Ditter, Benjamin M West
2025, Journal of Fish Biology (106) 481-491
Control and elimination of invasive fishes, like carps (Order Cypriniformes), may be possible by using chemical stimuli to congregate them for removal. To this end, we tested behavioral responses of grass (Ctenopharyngodon idella), bighead (Hypophthalmichthys nobilis), and silver carp (H. molitrix) to L-alanine, L-arginine, L-glutamic acid, and L-aspartic acid. In...
Edge effects along roadside fuel treatments in sagebrush steppe
Samuel J. Price, Matthew J. Germino, Chloe Rose Watt
2025, Rangeland Ecology and Management (98) 155-159
Increasing wildfire has motivated the construction of fuel breaks on many rangelands to improve prospects for wildfire suppression. However, the linear shape of fuel breaks greatly increases treatment perimeter: area and thus increased potential for edge effects, e.g., invasions by exotic plants. Potential for edge effects are further increased by...
No evidence hunting bait increases American black bear population growth in Maine, USA
Dana J. Morin, Jennifer H. Vashon, Matthew O’Neal, Nathan J. Hostetter, Elizabeth A. Flaherty
2025, Journal of Wildlife Management (89)
American black bear (Ursus americanus) populations are increasing throughout much of North America. Use of multiple harvest methods, including hunting over bait, is intended to increase harvest success rates to meet harvest and population management objectives. However, black bear population growth can be influenced by food availability, and some speculate...
Predation of Lost River and Shortnose suckers by piscivorous colonial waterbirds in the Upper Klamath Basin: An analysis of predation effects during 2021–2023
Nathan B Banet, Quinn Payton, Allen Evans, Rachael Katelyn Paul-Wilson, Jacob Richard Krause, Brian S. Hayes, Erin Marie Benham
2025, Report
Previously published research indicated that predation by piscivorous colonial waterbirds in the Upper Klamath Basin was a source of mortality for Lost River suckers (Deltistes luxatus) and Shortnose suckers (Chasmistes brevirostris), including mortality of Sucker Assisted Rearing Program (SARP) fish. Avian predation on recently released Chinook Salmon (Oncorhynchus tshawytscha) in...

2025, Rangeland Ecology & Management (98) 424-466
Pinyon–juniper (PJ) woodlands are among the most widespread ecosystems in rangelands of western North America, supporting diverse wildlife habitat, recreation, grazing, and cultural/spiritual enrichment. Anticipating future distribution shifts under changing climate will be critical to climate adaptation and conservation efforts in...

2025, Journal of Volcanology and Geothermal Research (455)
We describe three unique types of seismicity at Popocatépetl volcano that accompanied the initial vent-clearing eruptive activity in December 1994 through the eruption of the first two domes in 1996. We identify and describe two types of coupled events, 1) spasmodic burst coupled events, a burst of volcano tectonic (VT)...

Behavioural analysis has been attracting significant attention as a broad indicator of sub-lethal toxicity and has secured a place as an important subdiscipline in ecotoxicology. Among the most notable characteristics of behavioural research, compared to other established approaches in sub-lethal ecotoxicology (e.g. reproductive and developmental bioassays), are the wide range...
Multiscale processes drive formation of logjam habitats and use by juvenile Chinook salmon across a boreal stream network in Alaska
Charles N. Cathcart, Jeffrey A. Falke, Jimmy Fox, Robert Henszey, Katherine Lininger
2025, River Research and Applications (41) 593-608
Boreal forest streams are characterized by large volumes of instream wood, yet the relationship between logjams and Pacific salmon productivity remains underqualified. We located logjams (n = 427) within the distribution of Chinook salmon (Oncorhynchus tshawytscha) in the Chena River, Alaska (Yukon River tributary) and measured dimensions, classified formative process, and snorkel-sampled...

2025, Biodiversity and Conservation (33) 3703-3726
Monitoring provides the foundation for evaluating recovery of endangered species, yet many species lack monitoring programs designed to integrate a species’ unique attributes, specific monitoring objectives, and principles of statistical sampling theory. We developed a framework for monitoring and assessment of endangered light-footed Ridgway’s rails (Rallus obsoletus levipes) across their...
Quantitative support for the benefits of proactive management for wildlife disease control
Molly Bletz, Evan H. Campbell Grant, Graziella Vittoria DiRenzo
2025, Conservation Biology (39)
Finding effective pathogen mitigation strategies is one of the biggest challenges humans face today. In the context of wildlife, emerging infectious diseases have repeatedly caused widespread host morbidity and population declines of numerous taxa. In areas yet unaffected by a pathogen, a proactive management approach has the potential to minimize...
The impact of source time function complexity on stress drop estimates
James S. Neely, Sunyoung Park, Annemarie S. Baltay Sundstrom
2025, Bulletin of the Seismological Society of America (115) 1149-1161
Earthquake stress drop—a key parameter for describing the energetics of earthquake rupture—can be estimated in several different, but theoretically equivalent, ways. However, independent estimates for the same earthquakes sometimes differ significantly. We find that earthquake source complexity plays a significant role in...
