conservation in tropics

In a quite rich article about the conservation of biodiversity in the tropics:

du Toit, J.T., Walker, B.H. and Campbell, B.M. 2004. Conserving tropical nature: current challenges for ecologists. Trends in Ecology and Evolution 19 (1): 12-17.

du Toit et al. discuss important concepts for the conservation of tropical biodiversity. Among other things, they remember that conservation of biodiversity in the tropics is a global responsibility, and requires the commitment of firt-world citizens. I found interesting their statement that conservation practicioners should receive social rewards similars to those of medical doctors (for they carry out a similarly important work). They also discuss important ideas regarding different scale approaches, the importance of identifying ecological resilience theresholds, the role of protected areas, and others. From politics, to statistic approaches. A fairly good paper.
