Putative hydrological connectivity and scales of gene flow associated with the fauna (fishes and aquatic invertebrates) of arid zone aquatic habitats
| Aquatic habitat | Type of refugium/refuge | Putative hydrological connectivity | Putative scale of gene flow Aquatic Dispersers | Putative scale of gene flow Aerial Dispersers |
|---|---|---|---|---|
| Subterranean aquifers | Evolutionary | Low | Local | NA |
| Discharge springs (Great Artesian Basin) | Evolutionary & ecological | Low | Local | Biome |
| Outcrop springs | Ecological & ecological | Low | Local | Biome |
| Relict streams | Evolutionary & ecological | Moderate | Local | Regional |
| Riverine waterholes | Evolutionary & ecological | High | Watershed/drainage basin | Drainage basin/biome |
