A great talk that I had the pleasure of moderating was given by Taylor Ricketts of the World Wildlife Fund. He and an impressive team of conservation scientists have recently put together some spatially explicit software – InVEST – that quantifies the values of ecosystem services and compares those to biodiversity values (richness, endemism, etc.). A clever way to find the right balance between ecosystem functions that benefit humans and species preservation, this software and approach appears to be a great way to optimise land use in our changing environment. Definitely one to watch. The first paper describing this is by Erik Nelson and colleagues (including Ricketts) and will be appearing shortly in Frontiers in Ecology and the Environment.
