Guareschi, S. and South, J. orcid.org/0000-0002-6339-4225 (2024) Biological invasions in intermittent rivers and streams: current knowledge and future frontiers. Ecosistemas, 33 (1). 2600. ISSN 1132-6344
Abstract
Intermittent rivers and ephemeral streams (IRES) have been overlooked in invasion science as the characteristic drying - wetting regimes are assumed to be a barrier to invasion processes. Flow contraction/cessation limits the persistence and success of water-dependent invasive alien species (IAS) in most IRES, while flash floods may restrict limnophilic and strictly terrestrial ones. However, IRES are subject to multiple anthropogenic stressors that could ultimately favour the arrival and spread of IAS and their mosaic of dynamic habitats may theoretically support both terrestrial and aquatic IAS. Successful IAS are characterised by adaptations, traits and life histories which facilitate rapid, opportunistic exploitation of habitats and resources. Here, the potential invasibility of IRES is discussed along with a summary of current knowledge gaps, examples and challenges across different continents. IAS in IRES should be considered a cause for concern but also an intriguing study system to understand the mechanics of biological invasions under global change.
