... Sydney. Water levels in Thirlmere Lakes have fluctuated over time, but there has been a recent decline that is of significant concern. In this study, we examined over one year the species composition and richness of zooplankton (Rotifera, Cladocera and Copepoda) and abiotic conditions in Lakes...

... Using data from 57 sites across suburban Perth we tested the influence of Cat Density on species richness and community composition of passerine birds as well as on the presence/absence of 15 common passerine species. Cat Density was not a significant predictor of any of the dependent variables...
