Data from: Using ricelands to provide temporary shorebird habitat during migration

Gregory H. Golet, Candace Low, Simon Avery, Katie Andrews, Christopher J. McColl, Rheyna Laney & Mark D. Reynolds
To help mitigate large wetland losses in California, The Nature Conservancy launched a dynamic conservation incentive program to create temporary wetland habitats in harvested and fallow rice fields for shorebirds migrating along the Pacific Flyway. Farmers were invited to participate in a reverse auction bidding process and winning bids were selected based on their cost and potential to provide high quality shorebird habitat. This was done in 2014 and 2015, for separate enrollment periods that...

Data from: A test of the hierarchical model of litter decomposition

Mark A. Bradford, G. F. Veen, Anne Bonis, Ella M. Bradford, Aimee T. Classen, J. Hans C. Cornelissen, Thomas W. Crowther, Jonathan R. De Long, Gregoire T. Freschet, Paul Kardol, Marta Manrubia-Freixa, Daniel S. Maynard, Gregory S. Newman, Richard S. P. Van Logtestijn, Maria Viketoft, David A. Wardle, William R. Wieder, Stephen A. Wood & Wim H. Van Der Putten
Our basic understanding of plant litter decomposition informs the assumptions underlying widely applied soil biogeochemical models, including those embedded in Earth system models. Confidence in projected carbon cycle-climate feedbacks therefore depends on accurate knowledge about the controls regulating the rate at which plant biomass is decomposed into products such as CO2. Here, we test underlying assumptions of the dominant conceptual model of litter decomposition. The model posits that a primary control on the rate of...

Data from: Partial support for the central–marginal hypothesis within a population: reduced genetic diversity but not increased differentiation at the range edge of an island endemic bird

Kathryn M. Langin, T. Scott Sillett, W. Chris Funk, Scott A. Morrison & Cameron K. Ghalambor
Large-scale population comparisons have contributed to our understanding of the evolution of geographic range limits and species boundaries, as well as the conservation value of populations at range margins. The central–marginal hypothesis (CMH) predicts a decline in genetic diversity and an increase in genetic differentiation toward the periphery of species’ ranges due to spatial variation in genetic drift and gene flow. Empirical studies on a diverse array of taxa have demonstrated support for the CMH....

Data from: Novel fine-scale aerial mapping approach quantifies grassland weed cover dynamics and response to management

Carolyn M. Malmstrom, H. Scott Butterfield, Laura Planck, Christopher P. Long, Valerie T. Eviner & Christopher W. Long
Invasive weeds threaten the biodiversity and forage productivity of grasslands worldwide. However, management of these weeds is constrained by the practical difficulty of detecting small-scale infestations across large landscapes and by limits in understanding of landscape-scale invasion dynamics, including mechanisms that enable patches to expand, contract, or remain stable. While high-end hyperspectral remote sensing systems can effectively map vegetation cover, these systems are currently too costly and limited in availability for most land managers. We...

Data from: A century of changing flows: forest management changed flow magnitudes and warming advanced the timing of flow in a southwestern US river

Marcos D. Robles, Dale S. Turner & Jeanmarie A. Haney
The continued provision of water from rivers in the southwestern United States to downstream cities, natural communities and species is at risk due to higher temperatures and drought conditions in recent decades. Snowpack and snowfall levels have declined, snowmelt and peak spring flows are arriving earlier, and summer flows have declined. Concurrent to climate change and variation, a century of fire suppression has resulted in dramatic changes to forest conditions, and yet, few studies have...

Data from: Factoring economic costs into conservation planning may not improve agreement over priorities for protection

Paul R. Armsworth, Heather Bird Jackson, Seong-Hoon Cho, Melissa Clark, Joseph E. Fargione, Gwenllian D. Iacona, Taeyoung Kim, Eric R. Larson, Thomas Minney & Nathan A. Sutton
Conservation organizations must redouble efforts to protect habitat given continuing biodiversity declines. Prioritization of future areas for protection is hampered by disagreements over what the ecological targets of conservation should be. Here we test the claim that such disagreements will become less important as conservation moves away from prioritizing areas for protection based only on ecological considerations and accounts for varying costs of protection using return-on-investment (ROI) methods. We combine a simulation approach with a...

Data from: Applying a dryland degradation framework for rangelands: the case of Mongolia

Chantsallkham Jamsranjav, Robin S. Reid, Maria E. Fernandez-Gimenez, Altanzul Tsevlee, Baasandorj Yadamsuren & Michael Heiner
Livestock-caused rangeland degradation remains a major policy concern globally and the subject of widespread scientific study. This concern persists in part because it is difficult to isolate the effects of livestock from climate and other factors that influence ecosystem conditions. Further, degradation studies seldom use multiple plant and soil indicators linked to a clear definition of and ecologically-grounded framework for degradation assessment that distinguishes different levels of degradation. Here, we integrate two globally applicable rangeland...
