Ecosystem responses to a whole‐reservoir coarse woody habitat addition

open access: yesFisheries Management and Ecology, Volume 31, Issue 6, December 2024.
Abstract The addition of coarse woody habitat (CWH) is often used to mitigate the loss of natural structure in aging waterbodies. Ecosystem‐scale effects of large‐scale CWH additions and their influence on fish productivity have been assessed in oligotrophic, natural lakes, but need to be assessed in more ecosystems. Therefore, we tested the effects of

Dry season refuges, refugia and flow‐regime change in Mediterranean climate streams

open access: yesFreshwater Biology, Volume 69, Issue 11, Page 1607-1626, November 2024.
Abstract Climate change is causing stream flow regimes to change in many regions globally, including southwestern Australia (SWA) where many perennial streams have switched to intermittent flow regimes. In drier landscapes, ecological refuges and evolutionary refugia will become critical for conserving freshwater biodiversity.
