Grantham,Hedley S. Grantham,Cristián Samper,Stephanie Wang,Lars Laestadius,Rebecca K. Runting,Gustavo A. Silva-Chávez,Jamison Ervin,David B. Lindenmayer +31 more
TL;DR: It is argued that maintaining and, where possible, restoring the integrity of dwindling intact forests is an urgent priority for current global efforts to halt the ongoing biodiversity crisis, slow rapid climate change and achieve sustainability goals.
Journal ArticleDOI
A comparison of noninvasive techniques to survey carnivore communities in northeastern North America
Matthew E. Gompper,Roland Kays,Justina C. Ray,Scott D. LaPoint,Daniel A. Bogan,Jason R. Cryan +5 more
TL;DR: In this article, the authors assess the value of five non-invasive techniques based on results from two multi-year studies of carnivores (including members of Carnivora and Didelphidae) in New York forests.
Journal ArticleDOI

Samper,J. Silverman,Aurélie Shapiro,Bernardo B. N. Strassburg,T. Stevens,Emma J. Stokes,Richard N. Taylor,T. Tear,Robert Tizard,Oscar Venter,Piero Visconti +46 more
TL;DR: This work generates the first globally-consistent, continuous index of forest condition as determined by degree of anthropogenic modification, by integrating data on observed and inferred human pressures and an index of lost connectivity.
Journal ArticleDOI
Rescaling the Human Footprint: A tool for conservation planning at an ecoregional scale
Gillian Woolmer,Stephen C. Trombulak,Justina C. Ray,Patrick J. Doran,Mark G. Anderson,Robert F. Baldwin,Alexis J. Morgan,Eric W. Sanderson +7 more
TL;DR: In this article, the authors used the Human Footprint (HF) for the Northern Appalachian/Acadian ecoregion at a 90-m resolution using best available data on human settlement, access, land use change, and electrical power infrastructure.
Journal ArticleDOI
Spatial occupancy models for large data sets
TL;DR: This work states that recent research has revealed a hidden form of multicollinearity in such applications, which may lead to parameter bias if not explicitly addressed in occupancy models.
