Journal ArticleDOI
Positive interactions of nonindigenous species: invasional meltdown?
TL;DR: There is little evidence that interference among introduced species at levels currently observed significantly impedes further invasions, and synergistic interactions among invaders may well lead to accelerated impacts on native ecosystems – an invasional ‘meltdown’ process.
Journal ArticleDOI
Loss of foundation species: consequences for the structure and dynamics of forested ecosystems
Aaron M. Ellison,Michael S. Bank,Barton D. Clinton,Elizabeth A. Colburn,Katherine J. Elliott,Chelcy R. Ford,David R. Foster,Brian D. Kloeppel,Jennifer D. Knoepp,Gary M. Lovett,Jacqueline E. Mohan,David A. Orwig,Nicholas L. Rodenhouse,William V. Sobczak,Kristina A. Stinson,Jeffrey K. Stone,Christopher M. Swan,Jill Thompson,Betsy Von Holle,Jackson R. Webster +19 more
TL;DR: In this article, the authors show that the loss of foundation tree species changes the local environment on which a variety of other species depend and how this disrupts fundamental ecosystem processes, including rates of decomposition, nutrient fluxes, carbon sequestration, and energy flow.
Journal ArticleDOI
Ecological resistance to biological invasion overwhelmed by propagule pressure
TL;DR: This is the first experimental study to demonstrate the primacy of propagule pressure as a determinant of habitat invasibility in comparison with other candidate controlling factors.
Journal ArticleDOI
Economic impacts of non-native forest insects in the continental United States.
Juliann E. Aukema,Brian Leung,Kent Kovacs,Corey Chivers,Kerry O. Britton,Jeffrey Englin,Susan J. Frankel,Robert G. Haight,Thomas P. Holmes,Andrew M. Liebhold,Deborah G. McCullough,Betsy Von Holle +11 more
TL;DR: The damage estimates provide a crucial but previously missing component of cost-benefit analyses to evaluate policies and management options intended to reduce species introductions and could be similarly employed to estimate damages in other countries or natural resource sectors.
Journal ArticleDOI
Historical Accumulation of Nonindigenous Forest Pests in the Continental United States
Juliann E. Aukema,Deborah G. McCullough,Betsy Von Holle,Andrew M. Liebhold,Kerry O. Britton,Susan J. Frankel +5 more
TL;DR: A comprehensive species list to assess the accumulation rates of nonindigenous forest insects and pathogens established in the United States found sap feeders and foliage feeders dominated the comprehensive list, but phloem- and wood-boring insects and foliageFeeders were often more damaging than expected.
