2020, Geochemistry, Geophysics, Geosystems (21)
The major controls on the variability of ferromanganese (FeMn) crust composition have been generally described over the past 40 years; however, most compilation studies lack quantitative statistics and are limited to a small region of several seamounts or compare FeMn crusts from disparate areas of the global oceans. This study...
Spatial and temporal dynamics of Pacific capelin Mallotus catervarius in the Gulf of Alaska: Implications for ecosystem-based fisheries management
David W. McGowan, Esther Goldstein, Mayumi L. Arimitsu, Alison Dreary, Olav Ormseth, Alex DeRobertis, John Horne, Lauren Rogers, Matt Wilson, Kenneth Coyle, Kris Holderied, John F. Piatt, W.T. Stockhausen, Stephani Zador
2020, Marine Ecology Progress Series (637) 117-140
Pacific capelin Mallotus catervarius are planktivorous, small pelagic fish that serve an intermediate trophic role in marine food webs. Due to the lack of a directed fishery or monitoring of capelin in the Northeast Pacific, there is limited information on their distribution and abundance, and how spatio-temporal fluctuations in capelin density affects...
Nuisance Neonatives Guidelines for Assessing Range-Shifting Species
Brittany B. Laginhas, Toni Lyn Morelli, Audrey Barker-Plotkin, Evelyn M. Beaury, Elsa Cousins, Sydni Joubran, Michael Nelson, Sam Talbot, Bethany A. Bradley
2020, Report
Native species will need to shift their ranges northward and upslope to keep pace with climate change in the Northeast U.S. However, this may cause some range-shifting species to have undesirable consequences in their expanded range. We provide a framework to identify the likelihood that a range-shifting species will become...

Coerced regimes: Management challenges in the Anthropocene
D. G. Angeler, B. C. Chaffin, S. M. Sundstrom, A. S. Garmestani, Kevin L. Pope, D. R. Uden, D. Twidwell, Craig R. Allen
2020, Ecology and Society (25)
Management frequently creates system conditions that poorly mimic the conditions of a desirable self-organizing regime. Such management is ubiquitous across complex systems of people and nature and will likely intensify as these systems face rapid change. However, it is highly uncertain whether the costs (unintended consequences, including negative side effects)...
Condition bias of decoy-harvested light geese during the conservation order
Drew N. Fowler, Elisabeth B. Webb, Mark P. Vrtiska
2020, Journal of Wildlife Management (84) 33-44
Evidence that decoy harvest techniques primarily remove individuals of poorer body condition is well established in short-lived duck species; however, there is limited support for condition bias in longer-lived waterfowl species, such as geese, where decoy harvest is considered primarily additive because of their high natural survival...

Winter carry-over effects on spring body condition driven by agricultural subsidies to Lesser Snow Geese (Anser caersulscens caerulescens)
Drew N. Fowler, Elisabeth B. Webb, Mark P. Vrtiska, Keith A. Hobson
2020, Avian Conservation and Ecology (15) 1-11
Anthropogenic changes to landscapes associated with intensive agriculture often have deleterious effects on avian abundance. However, some species like the Lesser Snow Goose (Anser caerulescens caerulescens), can benefit from increases in agricultural crops on both wintering and migratory stopover sites. We investigated the influence of winter habitat use on spring...

The Mt. Carlton Au-Ag-Cu deposit, northern Bowen basin, northeastern Australia, is an uncommon example of a sublacustrine hydrothermal system containing economic high-sulfidation epithermal mineralization. The deposit formed in the early Permian and comprises vein- and hydrothermal breccia-hosted Au-Cu mineralization within a massive rhyodacite porphyry (V2 open pit) and stratabound Ag-barite...

Bug flows: Don’t count your midges until they hatch
Anya Metcalfe, Jeffrey Muehlbauer, Morgan Ford, Theodore Kennedy
2020, Newsletter
Usually when people hear about a “bug problem” it’s due to an undesirable overabundance of insects (think plague of locusts). In the Colorado River in Grand Canyon, however, we are faced with the opposite predicament: the river is essentially devoid of bugs. Aquatic insects are a fundamental component of a...

2020, OCS Study 2020-062
Atlantic Sturgeon (Acipenser oxyrinchus oxyrinchus) are a large-bodied anadromous fish that historically supported important fisheries along the east coast of the United States. Following years of overharvest and habitat degradation, populations experienced severe declines. In 2012, the National Marine Fisheries Service listed Atlantic Sturgeon under the Endangered Species Act (ESA;...
