Understanding the long-term effects of species invasions.
TLDR
The ecological and evolutionary processes that modulate the effects of invasive species over time are described, and it is argued that such processes are so widespread and important that ecologists should adopt a long-term perspective.Abstract:
We describe here the ecological and evolutionary processes that modulate the effects of invasive species over time, and argue that such processes are so widespread and important that ecologists should adopt a long-term perspective on the effects of invasive species. These processes (including evolution, shifts in species composition, accumulation of materials and interactions with abiotic variables) can increase, decrease, or qualitatively change the impacts of an invader through time. However, most studies of the effects of invasive species have been brief and lack a temporal context; 40% of recent studies did not even state the amount of time that had passed since the invasion. Ecologists need theory and empirical data to enable prediction, understanding and management of the acute and chronic effects of species invasions.read more

Alien species in fresh waters: ecological effects, interactions with other stressors, and prospects for the future
TL;DR: Biological invasions are numerous in fresh waters around the world and the number of alien species in freshwater ecosystems will increase in the future as new aliens are moved outside of their native ranges by humans, and as established aliens fill their potential ranges.

The Potential Conservation Value of Non‐Native Species
TL;DR: The proportion of non-native species that are viewed as benign or even desirable will slowly increase over time as their potential contributions to society and to achieving conservation objectives become well recognized and realized.
Journal ArticleDOI
Progress toward understanding the ecological impacts of nonnative species
TL;DR: 19 testable hypotheses that explain temporal and spatial variation in impact are identified and reviewed and highlight the importance of the functional ecology of the nonnative species and the structure, diversity, and evolutionary experience of the recipient community as general determinants of impact.

TL;DR: A method for categorising and comparing alien or invasive species in terms of how damaging they are to the environment, that can be applied across all taxa, scales, and impact metrics is presented.
Journal ArticleDOI
Assisted colonization is not a viable conservation strategy
TL;DR: It is argued that conservation biologists have not yet developed a sufficient understanding of the impacts of introduced species to make informed decisions regarding species translocations.

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.

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.

Impact: Toward a Framework for Understanding the Ecological Effects of Invaders

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.

TL;DR: This work explores the nature of these recent biotic exchanges and their consequences on evolutionary processes, and shows how flexibility in behavior, and mutualistic interactions, can aid in the success of invaders in their new environment.

TL;DR: There are very few valid generalizations about invasive species, so that it is only possible to make weak, probabilistic predictions about which species will invade (Gilpin 1990; Daehler & Strong 1993).
