The greenscape shapes surfing of resource waves in a large migratory herbivore
Ellen O. Aikens, Matthew J. Kauffman, Jerod Merkle, Samantha Dwinnell, Gary L. Fralick, Kevin L. Monteith
2017, Ecology Letters (20) 741-750
The Green Wave Hypothesis posits that herbivore migration manifests in response to waves of spring green-up (i.e. green-wave surfing). Nonetheless, empirical support for the Green Wave Hypothesis is mixed, and a framework for understanding variation in surfing is lacking. In a population of migratory mule deer (Odocoileus hemionus), 31% surfed...

James E. Whitney, Joanna B. Whittier, Craig P. Paukert, Julian D. Olden, Angela L. Strecker
2017, Reviews in Fish Biology and Fisheries (27) 463-479
Climate change is poised to alter the distributional limits, center, and size of many species. Traits may influence different aspects of range shifts, with trophic generality facilitating shifts at the leading edge, and greater thermal tolerance limiting contractions at the trailing edge. The generality of relationships between traits and range...
Quantile regression of microgeographic variation in population characteristics of an invasive vertebrate predator
Shane R. Siers, Julie A. Savidge, Robert Reed
2017, PLoS ONE (12) 1-19
Localized ecological conditions have the potential to induce variation in population characteristics such as size distributions and body conditions. The ability to generalize the influence of ecological characteristics on such population traits may be particularly meaningful when those traits influence prospects for successful management interventions. To characterize variability in invasive...
