Holocene variability in the intensity of wind-gap upwelling in the tropical eastern Pacific
Lauren T. Toth, Richard B. Aronson, Hai Cheng, R. Lawrence Edwards
2015, Paleoceanography (30) 1113-1131
Wind-driven upwelling in Pacific Panamá is a significant source of oceanographic variability in the tropical eastern Pacific. This upwelling system provides a critical teleconnection between the Atlantic and tropical Pacific that may impact climate variability on a global scale. Despite its importance to oceanographic circulation, ecology, and climate, little is...
Framework for modeling urban restoration resilience time in the aftermath of an extreme event
Varun Ramachandran, Suzanna K. Long, Thomas G. Shoberg, Steven Corns, Héctor Carlo
2015, Natural Hazards Review 1-11
The impacts of extreme events continue long after the emergency response has terminated. Effective reconstruction of supply-chain strategic infrastructure (SCSI) elements is essential for postevent recovery and the reconnectivity of a region with the outside. This study uses an interdisciplinary approach to develop a comprehensive framework to model resilience time....

Water masses, ocean fronts, and the structure of Antarctic seabird communities: putting the eastern Bellingshausen Sea in perspective
Christine A. Ribic, David G. Ainley, R. Glenn Ford, William R. Fraser, Cynthia T. Tynan, Eric J. Woehler
2015, Deep-Sea Research Part II: Topical Studies in Oceanography (58) 1695-1709
Waters off the western Antarctic Peninsula (i.e., the eastern Bellingshausen Sea) are unusually complex owing to the convergence of several major fronts. Determining the relative influence of fronts on occurrence patterns of top-trophic species in that area, therefore, has been challenging. In one of the few ocean-wide seabird data syntheses,...

Resilience of ponderosa and lodgepole pine forests to mountain pine beetle disturbance and limited regeneration
Jenny S. Briggs, Todd Hawbaker, Don Vandendriesche
2015, Forest Science (61) 689-702
After causing widespread mortality in lodgepole pine forests in North America, the mountain pine beetle (MPB) has recently also affected ponderosa pine, an alternate host species that may have different levels of resilience to this disturbance. We collected field data in ponderosa pine- and lodgepole pine-dominated forests attacked by MPB...
Comparison of reintroduction and enhancement effects on metapopulation viability
Samniqueka J Halsey, Timothy J. Bell, Kathryn McEachern, Noel B. Pavlovic
2015, Restoration Ecology (23) 375-384
Metapopulation viability depends upon a balance of extinction and colonization of local habitats by a species. Mechanisms that can affect this balance include physical characteristics related to natural processes (e.g. succession) as well as anthropogenic actions. Plant restorations can help to produce favorable metapopulation dynamics and consequently increase viability; however,...
Spatial scaling patterns and functional redundancies in a changing boreal lake landscape
David G. Angeler, Craig R. Allen, Daniel R. Uden, Richard K. Johnson
2015, Ecosystems (18) 889-902
Global transformations extend beyond local habitats; therefore, larger-scale approaches are needed to assess community-level responses and resilience to unfolding environmental changes. Using longterm data (1996–2011), we evaluated spatial patterns and functional redundancies in the littoral invertebrate communities of 85 Swedish lakes, with the objective of assessing their potential resilience to...

Luke A. Avery, Josh Korman, William R. Persons
2015, North American Journal of Fisheries Management (35) 671-680
Negative interactions of Rainbow Trout Oncorhynchus mykiss with endangered Humpback Chub Gila cypha pose challenges to the operation of Glen Canyon Dam (GCD) to manage for both species in the Colorado River. Operations to enhance the Rainbow Trout tailwater fishery may lead to an increase in downstream movement of the trout to areas where...

Zuzanna Zajac, Bradley Stith, Andrea C. Bowling, Catherine A. Langtimm, Eric D. Swain
2015, Ecology and Evolution (5) 2503-2517
Habitat suitability index (HSI) models are commonly used to predict habitat quality and species distributions and are used to develop biological surveys, assess reserve and management priorities, and anticipate possible change under different management or climate change scenarios. Important management decisions may be based on model results, often without a...
