Research within Indigenous communities has been criticised for lacking community engagement, for being exploitative, and for poorly explaining the processes of research. To address these concerns, and to ensure 'best practice', Jamieson, et al. (2012) recently published a summary of principles outlined by the NHMRC (2003) in "one short, accessible document". Here we expand on Jamieson et al.'s ...

Manipulating or introducing an auto-reproducing predator into the ecosystem may provide sustained biological control of pest populations. The selection of a biological agent should be based on its self-replicating capacity, preference for the target pest population in the presence of alternate natural...
