Virtual Issue: Invasive Species


Edited by Manuela González-Suárez and Pablo González-Moreno

March 2017

Invasive species represent a serious conservation and social problem. The abundance and geographical distribution of invasive organisms continues to increase globally and considerable efforts are currently devoted to better understand the current and potential invasive species and their impacts, as well as to explore which are the most effective management actions and policy decisions to prevent further problems. This virtual issue showcases recent work on invasive species published in the journals of the British Ecological Society. We grouped these studies into three non-exclusive themes that showcase the latest approaches to understand and manage invasive species.

A first theme is defined by papers that focus on characterizing what makes the perfect invasive species (invasiveness). These studies go beyond trait comparisons and explore changes in population dynamics, the role of genetic mixture, and the evolution of adaptations, also presenting new modelling approaches and improved datasets.

A second theme includes studies which address impacts on ecological processes. These papers evaluate the effects of invasives on species interactions (particularly of plants with herbivores, pollinators, and soil mutualistic fungi), explore broad scale ecosystem and community impacts, propose new metrics, and characterize the synergistic consequences of combined impacts like climate change and invasives.

The final theme includes studies that focus on management. These publications present new and more robust decision tools, showcase the application of methods like e-DNA sampling and spatial-explicit models to manage invasives across different stages, particularly establishment and spread, and highlight the importance of considering social costs and benefits and of engaging with practitioners.
