Positive interactions of nonindigenous species: invasional meltdown?
TLDR
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.Abstract:
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 that introduced species frequently interact with one another and that facilitative interactions are at least as common as detrimental ones. The population significance of these interactions has rarely been determined, but a great variety of types of direct and indirect interactions among individuals of different nonindigenous species is observed, and many are plausibly believed to have consequences at the population level. In particular, mutualisms between plants and the animals that disperse and/or pollinate them and modification of habitat by both animals and plants seem common and often important in facilitating invasions. 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.read more

TL;DR: In this article, the introduction of invasive species and identifying life history stages where management will be most effective are discussed. And evolutionary processes may be key features in determining whether invasive species establish and spread.

Inclusion of facilitation into ecological theory
TL;DR: In this paper, the role of facilitation in the organization of terrestrial and aquatic communities has been investigated, and the importance of a wide variety of facilitative interactions has been considered.

The role of propagule pressure in explaining species invasions.
TL;DR: Propagule pressure is proposed as a key element to understanding why some introduced populations fail to establish whereas others succeed and how the study of propagule pressure can provide an opportunity to tie together disparate research agendas within invasion ecology.

TL;DR: This paper argues that the total impact of an invader includes three fundamental dimensions: range, abundance, and the per-capita or per-biomass effect of the invader, and recommends previous approaches to measuring impact at different organizational levels, and suggests some new approaches.

Biological invasions by exotic grasses, the grass/fire cycle, and global change
TL;DR: Biological invasions into wholly new regions are a consequence of a far reaching but underappreciated component of global environmental change, the human-caused breakdown of biogeographic barriers to species dispersal.

An equilibrium theory of insular zoogeography
TL;DR: As the area of sampling A increases in a ecologically uniform area, the number of plant and animal species s increases in an approximately logarithmic manner, or s = bAk, (1) where k < 1, as shown most recently in in the detailed analysis of Preston (1962).
