Ginger Deason, Erin Seekamp, Adam Terando, Camila Rojas
2023, Tourism and Hospitality (4) 451-466
Climate change impacts on tourism are well documented, with most studies focusing on challenges facing ski or beach tourism. While non-ski, mountain tourism accounts for almost one fifth of tourism worldwide, there is a dearth of research on tourists’ perceptions of climate change impacts and their effects on tourism demand...

Updated decision analysis to inform multi-species salmonine management in Lake Michigan
Kelly Filer Robinson, Michael L. Jones, Richard Clark, Brian Roth, Jory Jonas, Iyob Tsehaye, Matthew S. Kornis, Benjamin A. Turschak, Daniel O’Keefe, Brian Brenton
2023, Cooperator Science Series FWS/CSS-154-2023
The recreational fishery for salmonine species in Lake Michigan (lake trout, Chinook salmon, coho salmon, steelhead, and brown trout) is largely maintained through stocking. Decisions about how many of each species to stock require an understanding of how to maintain a sustainable balance of predators (salmonine species) to prey (alewife)...

Lauren Toth, Travis A. Courtney, Michael A. Colella, Robert R. Ruzicka
2023, Frontiers in Marine Science (10)
Outbreaks of coral disease have been a dominant force shaping western Atlantic coral-reef assemblages since the late 1970s. Stony coral tissue loss disease (SCTLD) is nonetheless having an unprecedented impact in the region. Whereas numerous studies over the last decade have worked to characterize this novel pathogen and its...

Teresa J. Newton, Denise A. Mayer, James T. Rogala, Sean S. Madden, Brian R. Gray
2023, Aquatic Conservation: Marine and Freshwater Ecosystems (33) 1413-1430
The Hudson River, New York, was contaminated with polychlorinated biphenyls (PCBs) from two manufacturing plants over a period of approximately 30 years, and PCBs are still present in sediment and biota today. The river provides habitat for a variety of plants and animals, including native freshwater mussels. A remediation programme,...

Isothermal recombinant polymerase amplification and CRIPSR (CAS12A) assay detection of Renibacterium salmoninarum as an example for wildlife pathogen detection in environmental DNA samples
Erin D’Agnese, Dorothy M. Chase, Elizabeth Andruszkiewicz-Allan
2023, Journal of Wildlife Diseases (59) 545-556
Improving rapid detection methods for pathogens is important for research as we collectively aim to improve the health of ecosystems globally. In the northern hemisphere, the success of salmon (Oncorhynchus spp.) populations is vitally important to the larger marine, aquatic, and terrestrial ecosystems they inhabit. This has led to managers cultivating...
Evolutionary and ecological correlates of thiaminase in fishes
Freya Elizabeth Rowland, Cathy A. Richter, Donald E Tillitt, David Walters
2023, Scientific Reports (13)
Thiamine (vitamin B1) is required by all living organisms in multiple metabolic pathways. It is scarce in natural systems, and deficiency can lead to reproductive failure, neurological issues, and death. One major cause of thiamine deficiency is an overreliance on diet items containing the enzyme thiaminase. Thiaminase activity has been...

Elevation, canopy cover and grass cover structure patterns of seedling establishment in a subtropical post-fire restoration
Christopher Warneke, Lars Brudvig, Makani Gregg, Sierra McDaniel, Stephanie G. Yelenik
2023, Ecological Solutions and Evidence (4)
Ecological restoration is beneficial to ecological communities in this era of large-scale landscape change and ecological disruption. However, restoration outcomes are notoriously variable, which makes fine-scale decision-making challenging. This is true for restoration efforts that follow large fires, which are increasingly common as the climate changes.Post-fire restoration efforts, like...

Submersed macrophyte density regulates aquatic greenhouse gas emissions
Meredith E. Theus, Nicholas E. Ray, Sheel Bansal, Meredith A. Holgerson
2023, JGR Biogeosciences (128)
Shallow freshwater ecosystems emit large amounts of greenhouse gases (GHGs), such as carbon dioxide (CO2) and methane (CH4), yet emissions are highly variable. The role that aquatic macrophytes play in regulating aquatic GHG emissions is uncertain despite their ability to dominate shallow waterbodies. Here, we studied the...

2023, Science of the Total Environment (907)
Understanding sources of mercury (Hg) and methylmercury (MeHg) to a water body is critical for management but is often complicated by poorly characterized Hg inputs and in situ processes, such as inorganic Hg methylation. In this study, we determined inorganic Hg and MeHg concentrations...
Movement behavior, habitat selection, and functional responses to habitat availability among four species of wintering waterfowl in California
Cory T. Overton, Michael L. Casazza
2023, Frontiers in Ecology and Evolution (11)
Habitat selection analyses provide a window into the perceived value of habitats by animals and how those perceptions compare with other animals, change across time, or change in relation to availability (termed functional responses). Habitat selection analysis and functional responses can be used to develop strategies to avoid habitat limitations,...

Steven Mark Grodsky, Karl A. Roeder, Joshua W. Campbell
2023, Ecosphere (14)
Land-use change from solar energy development may affect desert ecosystems and the soils, plants, and animals therein, yet our understanding of these interactions is nascent. With their ubiquity, criticality as ecosystem constituents, and sensitivity to environmental variation, ants may be useful study organisms for elucidating ecological effects of solar energy...
