2021, Book chapter, From terranes to terrains: Geologic field guides on the construction and destruction of the Pacific Northwest
New findings about old puzzles occasion rethinking of the Grand Coulee, greatest of the scabland channels. Those puzzles begin with antecedents of current upper Grand Coulee. By a recent interpretation, the upper coulee exploited the former high-level valley of a preflood trunk stream that had drained to the southwest beside...

Song S. Qian, Jonathan G. Kennen, Jason May, Mary Freeman, Thomas F Cuffney
2021, Water Research (205)
A continuous-variable Bayesian network (cBN) model is used to link watershed development and climate change to stream ecosystem indicators. A graphical model, reflecting our understanding of the connections between climate change, weather condition, loss of natural land cover, stream flow characteristics, and stream ecosystem indicators is used as the basis for...

2021, Ichthyology & Herpetology 851-859
For species with variable phenology, it is often challenging to produce reliable estimates of population dynamics or changes in occupancy. The Arizona Toad (Anaxyrus microscaphus) is a southwestern USA endemic that has been petitioned for legal protection, but status assessments are limited by a lack of information...
Effects of variable-density thinning on non-native understory plants in coniferous forests of the Pacific Northwest
Yianna Bekris, Janet S. Prevey, Leslie C. Brodie, Connie Harrington
2021, Forest Ecology and Management (502)
Old-growth forests serve as critical habitat for many sensitive species, but management practices have diminished their prevalence, and former regions of old-growth are now dominated by second-growth stands lacking the structural heterogeneity, diversity, and species richness that these older forests possess. In...
Hypogenic karst of the Great Basin
Louise D. Hose, Harvey R. DuChene, Daniel Jones, Gretchen M. Baker, Zoe Havlena, Donald S. Sweetkind, Doug Powell
2021, Book chapter, Field Excursions from the 2021 GSA Section Meetings
Discoveries in the 1980s greatly expanded speleologists’ understanding of the role that hypogenic groundwater flow can play in developing caves at depth. Ascending groundwater charged with carbon dioxide and, especially, hydrogen sulfide can readily dissolve carbonate bedrock just below and above the water table. Sulfuric acid speleogenesis, in which anoxic,...

Alexandra G. Gulick, Anne B. Meylan, Peter A. Meylan, Kristen Hart, Jennifer A. Gray, Gaelle Roth, Alan B. Bolten, Karen A. Bjorndal
2021, Marine Biology (168)
Populations of the green turtle (Chelonia mydas), a mega-herbivore that consumes seagrasses, are recovering worldwide. Understanding green turtle adaptations to herbivory and responses to changes in seagrass availability will be critical to interpreting plant–herbivore interactions as green turtle populations continue to rebound. Ingesta particle size and...

Long-term epilimnetic temperature trends in Lake Mendota and Trout Lake, Wisconsin
Richard C Lathrop, Dale M. Robertson
2021, Report
Warming of lake surface waters has become a concern to limnologists and water managers because air temperatures, which directly affect near-surface water temperatures, are projected to increase in Wisconsin (WICCI 2011) as well as globally (IPCC 2018). This projected increase is in addition to the changes in air temperatures that...

Periodic oscillation and tri-stability in mutualism systems with two consumers
Yuanshi Wang, Hong Wu, Donald L. DeAngelis
2021, Journal of Mathematical Analysis and Applications (506)
This paper considers mutualistic interactions between two consumers, in which one consumer can consume a resource only by exchange of service for service with the other. By rigorous analysis on the one-resource and two-consumer model with Holling-type I response, we show periodic oscillations and tri-stability in the mutualism system: when...
Survival and abundance of polar bears in Alaska’s Beaufort Sea, 2001–2016
Jeffrey F. Bromaghin, David C. Douglas, George M. Durner, Kristin S. Simac, Todd C. Atwood
2021, Ecology and Evolution (11) 14250-14267
The Arctic Ocean is undergoing rapid transformation toward a seasonally ice-free ecosystem. As ice-adapted apex predators, polar bears (Ursus maritimus) are challenged to cope with ongoing habitat degradation and changes in their prey base driven by food-web response to climate warming. Knowledge of polar bear response to environmental change is...
Modelling presence versus abundance for invasive species risk assessment
Catherine S. Jarnevich, Helen Sofaer, Peder Engelstad
2021, Diversity and Distributions (27) 2454-2464
AimInvasive species prevention and management can be guided by comparisons of invasion risk across space and among species. Species distribution models are widely used to assess invasion risk and typically estimate suitability for species presence. However, suitability for presence may not capture patterns of abundance and impact....
