A lengthy list of international conservation biologists, fronted by the University of East Anglia’s Toby Gardner, has done just that, and just they’ve published their findings in Ecology Letters. After sampling a wide range of taxa at sites across 500 000 hectares of Brazilian Amazonia, birds and dung beetles shook out as being particularly good – and cheap – indicators of general biodiversity. However, focusing on these groups is a double-edged sword: on the one hand the money goes further, but on the other we remain ignorant of those poorly understood, expensive to study species.Source: Gardner TA, Barlow J, Araujo IS, Ávila-Pires TC, Bonaldo AB, Costa JE, Esposito MC, Ferreira LV, Hawes J, Hernandez MIM, Hoogmoed MS, Leite RN, Lo-Man-Hung NF, Malcolm JR, Martins MB, Mestre LAM, Miranda-Santos R, Overal WL, Parry L, Peters SL, Ribeiro-Junior MA, da Silva MNF, da Silva Motta & Peres CA (2007) The cost-effectiveness of biodiversity surveys in tropical forests.
