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

Globalization of trade and travel has facilitated the spread of non-native species across the
earth. A proportion of these species become established and cause serious environmental …

Introductions of non‐native freshwater fish continue to increase globally, although only a
small proportion of these introductions will result in an invasion. These invasive populations …

Non‐native species introductions affect freshwater communities by changing community
compositions, functional roles, trait occurrences and ecological niche spaces …

In this paper it is argued, using examples of disease emergence in aquatic animals in
Europe, that the introduction of non-native species drives disease emergence by both …

Correct species identification is fundamental for assessment and understanding of
biodiversity. Erroneous species identification may impede conservation management and …

Habitat fragmentation is a principal threat to biodiversity and artificial river barriers are a
leading cause of the global decline in freshwater biota. Although the impact of barriers on …

Non‐native fishes are often blamed for exerting adverse ecological impacts on native fishes,
but the evidence is circumstantial and the true impacts remain largely unknown. This …

Although the high costs of invasion are frequently cited and are a key motivation for
environmental management and policy, synthesised data on invasion costs are scarce …

Ecological theory attempts to predict how impacts for native species arise from biological
invasions. A fundamental question centres on the feeding interactions of invasive and native …
