2024, Wildlife Research (49) 698-708
Context: Vector-borne diseases have caused global pandemics and were responsible for more human deaths than all other causes combined in prior centuries. In the past 60 years, prevention and control programs have helped reduce human mortality from vector-borne diseases, but impacts of those control programs on wildlife populations are not well documented....
Recovery of working grasslands following a megafire in the southern mixed-grass prairie
Nicholas J. Parker, Daniel S. Sullins, David A. Haukos, Kent A. Fricke, Christian A. Hagen
2024, Global Ecology and Conservation (36)
While fire is a necessary ecological driver for grassland systems, Great Plains grasslands have undergone extensive land use change following European settlement (conversion, fragmentation, fire suppression, intensive grazing, etc.). Recent studies have documented the benefits of re-introducing fire to grasslands, but work has largely focused on small-scale, low-intensity fire, often at...

Bonneville Cutthroat Trout (BCT) Oncorhynchus clarkii utah in Bear Lake, Idaho–Utah, is an important endemic and recreational species and plays a vital ecological role in systems throughout the basin. Although the distribution and abundance of BCT have declined due to anthropogenic disturbances, production of wild BCT in Bear Lake has increased over...
Habitat selection in a southern Lake Sturgeon population: Implications of temporal, spatial, and ontogenetic variation for restoration
M.J. Moore, Craig P. Paukert, S. Owens, T. Moore
2024, Restoration Ecology (30)
Successful species reintroduction requires restoration of receiving habitats to support growth, survival, and reproduction that reverse the initial causes of decline. Little is known about whether present habitat conditions can support all life stages of reintroduced southern Lake Sturgeon populations that were possibly extirpated by the mid-1900s due to overharvest...
A latest Pleistocene and Holocene composite tephrostratigraphic framework for northeastern North America
Britta J.L. Jensen, Lauren J. Davies, Connor J. Nolan, Sean Pyne-O’Donnell, Alistair J. Monteath, Vera Ponomareva, Maxim Portnyagin, Robert K Booth, Marcus Bursik, Elizabeth Cook, Gill Plunkett, James W. Vallance, Yantao Luo, Les C. Cwynar, Paul Hughes, D. Graham Pearson
2024, Quaternary Science Reviews (272)
Lakes and bogs in northeastern North America preserve tephra deposits sourced from multiple volcanic systems in the Northern Hemisphere. However, most studies of these deposits focus on specific Holocene intervals and the latest Pleistocene, providing snapshots rather than a full picture. We combine new data with previous work, supplemented by...
Mapping and classification of volcanic deposits using multi-sensor unoccupied aerial systems
Brett B. Carr, Einat Lev, Theresa Sawi, Kristen A. Bennett, Christopher S. Edwards, S. Adam Soule, Silvia Vallejo Vargas, Gayatri Indah Marliyani
2024, Remote Sensing of Environment (264)
The deposits from volcanic eruptions represent the record of activity at a volcano. Identification, classification, and interpretation of these deposits are crucial to the understanding of volcanic processes and assessing hazards. However, deposits often cover large areas and can be difficult or dangerous to access, making field mapping dangerous and...
Effect of backwatering a streamgage weir on the passage performance of adult American Shad (Alosa sapidissima)
Kevin Mulligan, Alexander Haro, John Noreika
2024, Journal of Ecohydraulics (9) 145-157
Streamgage designs often include a full-width artificial hydraulic control (e.g., concrete weir) to aid in the computation of streamflow. While important to water resource managers, these weirs also tend to act as full or partial barriers to fish migration, effectively hindering the health and survival of these populations. In this...
Sharing knowledge to improve ecological restoration outcomes
Elise S Gornish, Molly L. McCormick, Marquel Begay, Mlungele M Nsikani
2024, Restoration Ecology (32)
Ecological restoration efforts are likely to be more successful when project components are informed by relevant stakeholders. However, key stakeholders are often not included in restoration design and deployment. This is largely driven by a lack of practitioner knowledge of and experience with stakeholder relations. However, inclusion of stakeholders across...
Historical and prehistorical water levels of Mormon Lake, Arizona as a measure of climate change on the southwest Colorado Plateau, USA
Richard Hereford, Lee Amoroso
2024, Quaternary Research (100) 32-51
Mormon Lake, elevation 2166 m with maximum historic surface area of 31.4 km2, lies in a forested endorheic basin covering 103 km2. It is the largest unaltered freshwater body on the 337,000 km2 Colorado Plateau. Prehistorical (before AD 1878) highstands were ca. 9 and 24 m relative to depocenter datum....
