Synergistic interactions of nonindigenous species : Invasional meltdown ?
Study of interactions between pairs or larger groups of nonindigenous species has been subordinated in the literature to study of interactions between nonindigenous and native species. To the extent that interactions among introduced species are depicted at all, the emphasis has been on negative interactions, primarily resource competition and interference. However, a literature search reveals ...

متن کاملEnemy release or invasional meltdown? Deer preference for exotic and native trees on Isla Victoria, Argentina
How interactions between exotic species affect invasion impact is a fundamental issue on both theoretical and applied grounds. Exotics can facilitate establishment and invasion of other exotics (invasional meltdown) or they can restrict them by re-establishing natural population control (as predicted by the enemyrelease hypothesis). We studied forest invasion on an Argentinean island where 43 s...
متن کاملBelowground legacies of Pinus contorta invasion and removal result in multiple mechanisms of invasional meltdown
Plant invasions can change soil biota and nutrients in ways that drive subsequent plant communities, particularly when co-invading with belowground mutualists such as ectomycorrhizal fungi. These effects can persist following removal of the invasive plant and, combined with effects of removal per se, influence subsequent plant communities and ecosystem functioning. We used field observations an...
متن کاملInvasional meltdown 6 years later: important phenomenon, unfortunate metaphor, or both?
Cases in which introduced species facilitate one another's establishment, spread, and impacts are increasingly noted, and several experimental studies have provided strong evidence of a population-level impact. However, a full 'invasional meltdown', in which interspecific facilitation leads to an accelerating increase in the number of introduced species and their impact, has yet to be conclusiv...
