Freshwater fish have been widely introduced worldwide, and freshwater ecosystems are
among those most affected by biological invasions. Consequently, freshwater fish invasions …

Invasive plant species can hinder the establishment and growth of native plants and impact
several ecosystem properties, such as soil cover, nutrient cycling, fire regimes and …

Land use and related pressures have reduced local terrestrial biodiversity, but it is unclear
how the magnitude of change relates to the recently proposed planetary boundary (“safe …

Ecology Letters (2011) 14: 702–708 Abstract Biological invasions cause ecological and
economic impacts across the globe. However, it is unclear whether there are strong patterns …

With the growing body of literature assessing the impact of invasive alien plants on resident
species and ecosystems, a comprehensive assessment of the relationship between invasive …

The study of positive species interactions is a rapidly evolving field in ecology. Despite
decades of research, controversy has emerged as to whether positive and negative …

To predict the threat of biological invasions to native species, it is critical that we understand
how increasing abundance of invasive alien species (IAS) affects native populations and …

A predictive understanding of the ecological impacts of nonnative species has been slow to
develop, owing largely to an apparent dearth of clearly defined hypotheses and the lack of a …

The world has increasingly relied on protected areas (PAs) to rescue highly valued
ecosystems from human activities, but whether PAs will fare well with bioinvasions remains …

Invasions by alien plants provide a unique opportunity to examine competitive interactions
among plants. While resource competition has long been regarded as a major mechanism …
