White-tailed deer (Odocoileus virginianus) are the most abundant and widespread cervid in North America. Genetic data are used as a tool to monitor populations and make management decisions for this game species. However, the development and use of genomic tools that can generate a set of markers suitable for longitudinal...

Brendan K Hobart, Daniel A. Grear, Megan Winzeler, Travis Mcdevitt-Galles, Timothy M Korpita, Erin L. Muths, Valerie J McKenzie
2026, Oikos (2026)
Temperature is a primary driver of heterogeneity in host–pathogen dynamics and understanding how patch-scale temperature affects landscape-scale patterns of pathogen infection is key to effective monitoring and management. In field studies, both temperature variability and mean temperature are often related to infection of ectothermic animals by fungal pathogens, and although...

Emily L. Weiser, Katherine Christie, Casey T. Burns, Julie C Hagelin, Steven M. Matsuoka, James A. Johnson, Colleen M. Handel
2026, Ornithological Applications (128) 1-14
The boreal forest biome is an important breeding area for migratory birds and is undergoing rapid changes, including drying of wetlands, changes to vegetation composition, and human development. Many boreal bird populations are declining, but information is often lacking on how these species associate with habitat characteristics and thus how...

Carl Tape, Marco Aquino-Lopez, Sean Bemis, Peter J. Haeussler, Jessalyn Ginnaty
2026, Bulletin of the Seismological Society of America (116) 322-354
The 2002 Mw 7.9 earthquake in central Alaska ruptured 340 km on three faults—Susitna Glacier thrust fault, Denali fault, Totschunda fault—crossing both the Richardson Highway and the Alaska Pipeline. Its occurrence prompted renewed interest in historical large earthquakes that possibly originated on the Denali fault. One of these earthquakes was a Ms 7.2...

Nicholas S. Voss, Michael C. Quist
2026, North American Journal of Fisheries Management (46) 259-268
ObjectiveLength and weight indices (e.g., proportional size distribution, relative weight) provide standardized benchmarks that are useful for comparing groups of fish, identifying ecological interactions, and evaluating the effect of management actions. However, the current length categories and standard weight (Ws) equation for Northern Pikeminnow Ptychocheilus oregonensis, a species of important management...

Blake Logan, Mark Pegg, Kirk D. Steffensen, Jonathan J. Spurgeon
2026, North American Journal of Fisheries Management (46) 70-83
ObjectiveKnowledge of invasive Silver Carp Hypophthalmichthys molitrix population demographics and distributions may inform estimates of efforts necessary to achieve reductions in abundance and identify locations to conduct removal. Although extensively studied in other parts of their invasive range (e.g., Mississippi and Illinois rivers), less is known regarding Silver Carp population demographics in...

2026, Journal of Hydrology (664)
This study examines the spatial variability of shallow groundwater on Dhigelaabadhoo Island using electromagnetic induction surveys, groundwater monitoring, and sediment analyses. The research reveals how variations in island morphology—such as differences in elevation, reef flat width, and sediment composition—affect the spatial distribution of groundwater lenses and the overall aquifer dynamics....
Variation in soil organic carbon across a latitudinal chronosequence of mangrove poleward expansion
Yiyang Kang, Prakhin Assavapanuvat, Michael J. Osland, David A. Kaplan
2026, Ecosystems (29)
The critical carbon sink provided by coastal wetlands, known as blue carbon, can be affected by multiple aspects of climate change. One important example is warming-induced mangrove poleward expansion, which is shifting dominant plant cover across tropical–temperate transitional zones and altering ecosystem structure and function. We examined how mangrove expansion...

During a two-week field sampling expedition in Gabon, two American scientists consumed fish daily from the Ogooué River watershed. We sampled their scalp and facial hair periodically to evaluate hair as a biomarker to track shifts in methylmercury (MeHg) exposure from diet. Each individual differed in the onset and extent...
High-precision earthquake catalog for Minto Flats fault zone, central Alaska, reveals complex and conjugate faulting
Nealey E. Sims, Carl Tape, Natalia A. Ruppert, Michael E. West
2026, Bulletin of Seismological Society of America (116) 375-396
The Minto Flats fault zone (MFFZ) in central Alaska is a left‐lateral strike‐slip fault system situated between the continental‐scale right‐lateral Denali and Kaltag‐Tintina faults. The MFFZ has the potential to generate magnitude 7 earthquakes, and it hosted a magnitude 6 earthquake in 1995. It has also produced exotic events, such...

Year-round daytime pCO2 undersaturation in an instream series of urban reservoirs with a history of harmful algal blooms
Reynaldo Patino, Samantha Lehker
2026, Inland Waters (16)
Daytime water quality was determined monthly over two years in an instream series of four urban reservoirs with recurring blooms of Prymnesium parvum—a cool-season toxigenic species. Temperature, pH, and laboratory-measured total alkalinity were used to estimate pCO2. System-wide, pCO2 was negatively associated with dissolved oxygen. Chlorophyll-a, phycocyanin (cyanobacterial pigment), and P. parvum were negatively associated with pCO2 and...

Seasonal body mass dynamics mediate life-history trade-offs in a hibernating mammal
Austin Z.T. Allison, Courtney J. Conway, Amanda R. Goldberg, Alice E. Morris, Emma C. Hakanson
2026, Journal of Animal Ecology (95) 383-396
1. Energetic acquisition and growth are key traits that affect demography and life-history strategies. Many animals that live in seasonal environments in which food availability fluctuates store energy endogenously as fat in anticipation of food shortage. Fat-storing mammalian hibernators are an extreme example of this strategy where the optimal resolution...

Abigail J. Lynch, T. Douglas Beard Jr., Craig P. Paukert
2026, Fisheries (51) 14-17
Climate change was barely a blip on the radar for inland fisheries management 20 years ago. Today, it's a central focus. A 2016 paper helped shift conversations, sparked adaptation efforts across fisheries management. The future is still uncertain, but adaptation is key to sustaining these important resources....
