    • Early Warning Signals of Ecological Transitions: Methods for Spatial Patterns 

      Kéfi, Sonia; Guttal, Vishwesha; Brock, William A.; Carpenter, Stephen R.; Ellison, Aaron M.; Livina, Valerie N.; Seekell, David A.; Scheffer, Marten; van Nes, Egbert H.; Dakos, Vasilis (Public Library of Science, 2014)
      A number of ecosystems can exhibit abrupt shifts between alternative stable states. Because of their important ecological and economic consequences, recent research has focused on devising early warning signals for ...

    • Four Centuries of Change in Northeastern United States Forests 

      Thompson, Jonathan R.; Carpenter, Dunbar N.; Cogbill, Charles V.; Foster, David R. (Public Library of Science, 2013)
      The northeastern United States is a predominately-forested region that, like most of the eastern U.S., has undergone a 400-year history of intense logging, land clearance for agriculture, and natural reforestation. This ...

    • Multiple Browsers Structure Tree Recruitment in Logged Temperate Forests 

      Faison, Edward K.; DeStefano, Stephen; Foster, David R.; Rapp, Joshua M.; Compton, Justin A. (Public Library of Science, 2016)
      Historical extirpations have resulted in depauperate large herbivore assemblages in many northern forests. In eastern North America, most forests are inhabited by a single wild ungulate species, white-tailed deer (Odocoileus ...

    • Novel and Lost Forests in the Upper Midwestern United States, from New Estimates of Settlement-Era Composition, Stem Density, and Biomass 

      Goring, Simon J.; Mladenoff, David J.; Cogbill, Charles V.; Record, Sydne; Paciorek, Christopher J.; Jackson, Stephen T.; Dietze, Michael C.; Dawson, Andria; Matthes, Jaclyn Hatala; McLachlan, Jason S.; Williams, John W. (Public Library of Science, 2016)
      Background: EuroAmerican land-use and its legacies have transformed forest structure and composition across the United States (US). More accurate reconstructions of historical states are critical to understanding the ...

    • Statistically-Estimated Tree Composition for the Northeastern United States at Euro-American Settlement 

      Paciorek, Christopher J.; Goring, Simon J.; Thurman, Andrew L.; Cogbill, Charles V.; Williams, John W.; Mladenoff, David J.; Peters, Jody A.; Zhu, Jun; McLachlan, Jason S. (Public Library of Science, 2016)
      We present a gridded 8 km-resolution data product of the estimated composition of tree taxa at the time of Euro-American settlement of the northeastern United States and the statistical methodology used to produce the ...
