Journal ArticleDOI
Random Forests for Classification in Ecology
D. Richard Cutler,Thomas C. Edwards,Thomas C. Edwards,Karen H. Beard,Adele Cutler,Kyle Hess,Jacob Gibson,Joshua J. Lawler +7 more
TL;DR: High classification accuracy in all applications as measured by cross-validation and, in the case of the lichen data, by independent test data, when comparing RF to other common classification methods are observed.
Journal ArticleDOI
Global threats from invasive alien species in the twenty-first century and national response capacities
Regan Early,Bethany A. Bradley,Jeffrey S. Dukes,Joshua J. Lawler,Julian D. Olden,Dana M. Blumenthal,Patrick Gonzalez,Edwin D. Grosholz,Inés Ibáñez,Luke P. Miller,Cascade J. B. Sorte,Andrew J. Tatem +11 more
TL;DR: It is found that one-sixth of the global land surface is highly vulnerable to invasion, including substantial areas in developing economies and biodiversity hotspots, and there is a clear need for proactive invasion strategies in areas with high poverty levels, high biodiversity and low historical levels of invasion.
Journal ArticleDOI

TL;DR: A research agenda on nature contact and health is proposed, identifying principal domains of research and key questions that, if answered, would provide the basis for evidence-based public health interventions.
Journal ArticleDOI
Machine Learning Methods Without Tears: A Primer for Ecologists
TL;DR: An introduction to three machine learning approaches that can be broadly used by ecologists: classification and regression trees, artificial neural networks, and evolutionary computation.
