Journal ArticleDOI
The biodiversity of species and their rates of extinction, distribution, and protection
Stuart L. Pimm,Clinton N. Jenkins,Robin Abell,Thomas M. Brooks,John L. Gittleman,Lucas Joppa,Peter H. Raven,Callum M. Roberts,Joseph O. Sexton +8 more
TL;DR: The biodiversity of eukaryote species and their extinction rates, distributions, and protection is reviewed, and what the future rates of species extinction will be, how well protected areas will slow extinction Rates, and how the remaining gaps in knowledge might be filled are reviewed.
Journal ArticleDOI
Habitat fragmentation and its lasting impact on Earth’s ecosystems
Nick M. Haddad,Lars A. Brudvig,Jean Clobert,Kendi F. Davies,Andrew Gonzalez,Robert D. Holt,Thomas E. Lovejoy,Joseph O. Sexton,Mike P. Austin,Cathy D. Collins,William M. Cook,Ellen I. Damschen,Robert M. Ewers,Bryan L. Foster,Clinton N. Jenkins,Andrew J. King,William F. Laurance,Douglas J. Levey,Chris Margules,Chris Margules,Brett A. Melbourne,A. O. Nicholls,A. O. Nicholls,John L. Orrock,Dan-Xia Song,John R. Townshend +25 more
TL;DR: An analysis of global forest cover is conducted to reveal that 70% of remaining forest is within 1 km of the forest’s edge, subject to the degrading effects of fragmentation, indicating an urgent need for conservation and restoration measures to improve landscape connectivity.

Global, 30-m resolution continuous fields of tree cover: Landsat-based rescaling of MODIS vegetation continuous fields with lidar-based estimates of error
Joseph O. Sexton,Xiao-Peng Song,Min Feng,Praveen Noojipady,Anupam Anand,Chengquan Huang,Do-Hyung Kim,K. M. Collins,Saurabh Channan,C. Dimiceli,John R. Townshend +10 more
TL;DR: A global, 30-m resolution dataset of percent tree cover by rescaling the 250-m MOderate-resolution Imaging Spectroradiometer (MODIS) Vegetation Continuous Fields (VCF) Tree Cover layer using circa- 2000 and 2005 Landsat images, incorporating the MODIS Cropland Layer to improve accuracy in agricultural areas.
Journal ArticleDOI
US protected lands mismatch biodiversity priorities.
TL;DR: The United States protected areas do not adequately cover the country’s unique species, and specific areas deserving additional protection are recommended, some of them including public lands, but many others requiring private investment.
