Kyle T. Aune, Dean B. Gesch, Genee S. Smith
2020, Environmental Research (185)
BackgroundHurricane Katrina made landfall in New Orleans, Louisiana as a Category 3 storm in August 2005. Storm surges, levee failures, and the low-lying nature of New Orleans led to widespread flooding, damage to over 70% of occupied housing, and evacuation of 80–90% of city...

Filstrup, Ephraim M. Hanks, Jean-Francois Lapierre, Noah R. Lottig, Erin M. Schliep, Tyler Wagner, Katherine E. Webster
2020, Ecological Applications (30)
Although ecosystems respond to global change at regional to continental scales (i.e., macroscales), model predictions of ecosystem responses often rely on data from targeted monitoring of a small proportion of sampled ecosystems within a particular geographic area. In this study, we examined how the sampling strategy used to collect data...

Nicholas E. Young, Catherine S. Jarnevich, Helen Sofaer, Ian S. Pearse, Julia Sullivan, Peder Engelstad, Thomas J. Stohlgren
2020, PLoS ONE (15)
Predictions of habitat suitability for invasive plant species can guide risk assessments at regional and national scales and inform early detection and rapid-response strategies at local scales. We present a general approach to invasive species modeling and mapping that meets objectives at multiple scales. Our methodology is designed...
Estimating population abundance with a mixture of physical capture and passive PIT tag antenna detection data
Mary M. Conner, Phaedra E. Budy, Richard A. Wilkison, Michael Mills, David Speas, Peter D. Mackinnon, Mark C. Mckinstry
2020, Canadian Journal of Fisheries and Aquatic Sciences (77) 1163-1171
The inclusion of passive interrogation antenna (PIA) detection data has promise to increase precision of population abundance estimates (). However, encounter probabilities are often higher for PIAs than for physical capture. If the difference is not accounted for, may be biased....
Assessing population-level consequences of anthropogenic stressors for terrestrial wildlife
Todd E. Katzner, Melissa A. Braham, Tara Conkling, James E. Diffendorfer, Adam E. Duerr, Scott R. Loss, David M. Nelson, Hannah B. Vander Zanden, Julie L. Yee
2020, Ecosphere (11)
Human activity influences wildlife. However, the ecological and conservation significances of these influences are difficult to predict and depend on their population‐level consequences. This difficulty arises partly because of information gaps, and partly because the data on stressors are usually collected in a count‐based manner (e.g., number of dead animals)...
A socio-environmental geodatabase for integrative research in the transboundary Rio Grande/Río Bravo basin
Jennifer Villa
2020, Report
Management of water resources in the transboundary Rio Grande/Río Bravo Basin (the Basin) presents challenges for state and Federal entities in the United States and Mexico making management decisions on shared water resources. Damming, channelization, water availability, and allocation are governed by water rights and water-sharing agreements. Data and...

Sasha C. Reed, Robin H. Reibold, Molly A. Cavaleri, Aura M. Alonso-Rodriguez, Megan E. Berberich, Tana E. Wood
2020, Book chapter, Advances in Ecological Research
Tropical forests represent 50% of the planets species and play a disproportionately large role in determining climate due to the vast amounts of carbon they store and exchange with the atmosphere. Currently, disturbance patterns in tropical ecosystems are changing due to factors such...

Brent G. Delbridge, Joshua D. Carmichael, Robert M. Nadeau, David R. Shelly, Roland Burgmann
2020, Journal of Geophysical Research (125)
Tremor and low-frequency earthquakes are presumed to be indicative of surrounding slow, aseismic slip that is often below geodetic detection thresholds. This study uses data from borehole seismometers and long-baseline laser strainmeters to observe both the seismic and geodetic signatures of episodic tremor and slip on the Parkfield region of...

Biogeography of fire regimes in western US conifer forests: A trait-based approach
Jens Stevens, Matthew M. Kling, Dylan W. Schwilk, J. Morgan Varner, Jeffrey M. Kane
2020, Global Ecology and Biogeography (29) 944-955
Aim Functional traits are a critical link between species distributions and the ecosystem processes that structure those species’ niches. Concurrent increases in the availability of functional trait data and our ability to model species distributions present an opportunity to develop functional trait biogeography, i.e. the mapping of functional traits across space....

Climate dipoles as continental drivers of plant and animal populations
Benjamin Zuckerberg, Courtenay Strong, Jalene M. LaMontagne, Scott St. George, Julio L. Betancourt, Walter D. Koenig
2020, Trends in Ecology and Evolution (35) 440-453
Ecological processes, such as migration and phenology, are strongly influenced by climate variability. Studying these processes often relies on associating observations of animals and plants with climate variability indices, such as the El Niño–Southern Oscillation. A characteristic of climate indices is the simultaneous emergence of opposite extremes of temperature and...
Causal effect of impervious cover on annual flood magnitude for the United States
Annalise G. Blum, Paul J. Ferraro, Stacey A. Archfield, Karen R. Ryberg
2020, Geophysical Research Letters (47)
Despite consensus that impervious surfaces increase flooding, the magnitude of the increase remains uncertain. This uncertainty largely stems from the challenge of isolating the effect of changes in impervious cover separate from other factors that also affect flooding. To control for these factors, prior study designs...

Michael J. Manfredo, Tara L. Teel, Andrew W. Don Carlos, Leeann Sullivan, Alan D. Bright, Alia M. Dietsch, Jeremy Bruskotter, David C. Fulton
2020, Conservation Biology (34) 1549-1559
We introduced a multilevel model of value shift to describe the changing social context of wildlife conservation. Our model depicts how cultural-level processes driven by modernization (e.g., increased wealth, education, and urbanization) affect changes in individual-level cognition that prompt a shift from domination to mutualism wildlife...
