Slide 2: Aspects and levels of biodiversity
Biodiversity can be thought of as having three aspects (composition, structure and function) and three levels (the gene, the population and the ecosystem). Almost all systematic conservation planning tools focus at the species composition level (where the red dot is in this diagram). Some deal with biome or habitat modelling (red ellipse). The subject of this presentation is ecosystem function modelling (orange ellipse), which also deal to a degree with ecosystem structure. Clearly, there are gaps that current modelling processes do not cover, but when the three different approaches are combined, they do give a moderately clear picture of how it all works.
