Freshwater is a critical driver for island ecosystems. In Hawaiʻi, though rainfall intensity has increased, total rainfall has been on the decline for the last two decades and, as a result, streamflow has also been reduced. The changes in dynamic patterns of streamflow could result in impacts to river, estuarine, and coastal habitats. In turn, these changes also affect the nine native Hawaiian aquatic species found in these habitats at different stages of their amphidromous life cycle (in which they migrate from fresh to salt water or vice versa). To examine how changes in streamflow regime have impacted habitat quality for native migratory aquatic species, an ongoing project has been examining statewide long-term stream records [...]
