摘要: A global biodiversity hotspot, south-western Australia is characterised by a highly endemic freshwater fish fauna that severely impacted habitat alterations. As the case with many rivers in this region, Blackwood River secondarily salinised as consequence of agricultural practices and has caused population depletions halo-intolerant fishes. This study first to examine role groundwater intrusion maintaining connectivity for an obligate river. We determined significance nonsaline migratory routes cobbler, Tandanus bostocki during prolonged annual dry periods; characteristic Mediterranean climatic zones. undertook large, yet spatially temporally variable, localised movements through riffles. During baseflow, period major influence, were significantly associated discharge. Analysis gonadal development suggested such not strictly related reproduction probably foraging purposes. The reveals crucial riffles suggests T. may be reliably used indicator aquatic light extractions also continued rainfall reductions region due climate change.
