Introductions of exotic fish into freshwater ecosystems have often resulted in significant
changes to the natural communities (McDowall, 1968; Smith, 1968; Lachner et al., 1970; …

A heuristic framework for understanding and predicting the distribution and categorical

River networks are hierarchical dendritic habitats embedded within the terrestrial landscape,
with varying connectivity between sites depending on their positions along the network. This …

Invaders can influence freshwater systems at the individual, population, community and
ecosystem levels. Some of these impacts may be subtle or not easily predicted but they may …

There is growing awareness that predicting biological invasions will require the
development of conceptual models for specific taxa at appropriate scales. Salmonids are …

The galaxioid fishes are the dominant, most speciose group of freshwater fishes (with> 50
