THE TERRESTRIAL AND SEMI-AQUATIC INVERTEBRATES OF INTERMITTENT RIVERS AND EPHEMERAL STREAMS
Intermittent rivers and ephemeral streams (IRES) are the most abundant waterways on earth. They can support a diverse and often abundant terrestrial and semi-aquatic invertebrate (TSAI) fauna. TSAIs can inhabit a variety of habitats, including the shoreline, the surface of exposed gravel bars, unsaturated gravels, dry riverbeds, riparian zones, and floodplains. Much less is known about the species composition and ecological roles of TSAIs of IRES than their aquatic counterparts, with TSAIs being largely overlooked in conceptual models, legislation, policy, and ecological monitoring.
Here we introduce TSAIs, and present conceptual models describing how they respond to hydrological changes in IRES. We then test these models with data collected during wet and dry phases in IRES from Australia and France. These generic models can be utilised by water managers and policy makers, ensuring that both wet and dry phases are considered in the management and protection of IRES. IRES should be viewed as a habitat continuum through time, with taxa from a pool of aquatic, semi-aquatic and terrestrial invertebrates inhabiting at any hydrological stage. We call for collaboration among terrestrial, lentic, and lotic ecologists to further explore these invertebrates and ecosystems.
