2023, Conservation Physiology (11)
Rapid and accelerating warming of salmon habitat has the potential to lower productivity of Pacific salmon (Oncorhynchus species) populations. Heat stress biomarkers can indicate where warming is most likely affecting fish populations; however, we often lack clear classifications that separate individuals with and without heat stress needed to make these...

Competition between dissolved organic matter and freshwater plankton control methylmercury isotope fractionation during uptake and photochemical demethylation
Grace Jane Armstrong, Sarah E. Janssen, Brett A. Poulin, Michael T. Tate, David P. Krabbenhoft, James P. Hurley
2023, ACS Earth and Space Chemistry (7) 2382-2392
Isotope fractionation related to photochemical reactions and planktonic uptake at the base of the food web is a major uncertainty in the biological application of mercury (Hg) stable isotopes. In freshwater systems, it is unclear how competitive interactions among methylmercury (MeHg), dissolved organic matter (DOM), and phytoplankton govern the magnitude...

2023, Genome Biology and Evolution (15)
Urosaurus nigricaudus is a phrynosomatid lizard endemic to the Baja California Peninsula in Mexico. This work presents a chromosome-level genome assembly and annotation from a male individual. We used PacBio long reads and HiRise scaffolding to generate a high-quality genomic assembly of 1.87 Gb distributed in 327 scaffolds, with an N50...
Reservoir stratification modulates the influence of impoundments on fish mercury concentrations along an arid land river system
James Willacker, Collin Eagles-Smith, Jim Chandler, Jesse Naymik, Ralph Myers, David P. Krabbenhoft
2023, Environmental Science & Technology (57) 21313-21326
Impoundment is among the most common hydrologic alterations with impacts on aquatic ecosystems that can include effects on mercury (Hg) cycling. However, landscape-scale differences in Hg bioaccumulation between reservoirs and other habitats are not well characterized nor are the processes driving these differences. We examined total Hg (THg) concentrations of...

2023, Frontiers in Ecology and Evolution (11)
Large dam removals are increasing in frequency and the response of natural and managed revegetation is a critical consideration for managed restoration of dewatered reservoir landscapes post dam removal. The removal of two large dams on the Elwha River in 2011-2014 provides insight into reservoir revegetation. We review literature...
Selection of microhabitats, plants, and plant parts eaten by a threatened tortoise: Observations during a superbloom
W. Bryan Jennings, Kristin H. Berry
2023, Frontiers in Amphibian and Reptile Science (1)
Populations of the threatened desert tortoise (Gopherus agassizii) continue to decline throughout the geographic range, in part because of degraded and fragmented habitats in the Mojave and western Sonoran deserts. The species is herbivorous and highly selective in choice of plant species. To increase options for recovery, we analyzed behaviors,...

2023, Frontiers in Microbiology (14)
The emergence of ophidiomycosis (or snake fungal disease) in snakes has prompted increased awareness of the potential effects of fungal infections on wild reptile populations. Yet, aside from Ophidiomyces ophidiicola, little is known about other mycoses affecting wild reptiles. The closely related genus Paranannizziopsis has been associated with dermatomycosis in snakes...

Marcan Graffin, Mohsen Taherkhani, Meredith Leung, Sean Vitousek, George Kaminsky, Peter Ruggiero
2023, Coastal Futures (1)
Coastal morphological changes can be assessed using shoreline position observations from space. However, satellite-derived waterline (SDW) and shoreline (SDS; SDW corrected for hydrodynamic contributions and outliers) detection methods are subject to several sources of uncertainty and inaccuracy. We extracted high-spatiotemporal-resolution (~50 m-monthly) time series of mean high water...

Marta Ulaski, Joshua McCormick, Michael Quist, Zachary Jackson
2023, Journal of Fish and Wildlife Management (14) 324-336
Traditional methods for estimating abundance of fish populations are not feasible in some systems due to complex population structure and constraints on sampling effort. Lincoln’s estimator provides a technique that uses harvest and harvest rate to estimate abundance. Using angler catch data allows assumptions of the estimator to be addressed...
