Coral reef planktivores are important to coral reefs by concentrating and delivering nutrients and allochthonous carbon from the plankton to reef building corals. In an otherwise very oligotrophic system this function may be of major importance. Planktivorous Damselfish (Pomicentridae) were analysed for prey selectivity through enumeration of stomach contents. Simultaneous plankton tows were conducted to establish the plankton community composition of the waters they were taken from. There was a statistically significant variation between the stomach composition and that of the water column. While there was not a significant difference among Simpson’s diversity indices of the stomach contents, there was …

Organisms select habitats that provide the best possible resources necessary to their survival. Organisms may occupy and utilize a home range which requires specific selection of components in their available habitat. Monitoring the threats to a species within their habitats is a crucial tool in conservation and management practices. The Murray-Darling Basin of south-eastern Australia has suffered alterations to its hydrology, flow regime, catchment size and usage, flooding cycles, as well as from vast removal of vegetation in the floodplains since European settlement in Australia in the mid-nineteenth century. Knowledge of the habitat use of a focal species can guide …
