Abstract:

One of the great concerns with climate change and global change more
generally is the effect on the diversity of life on the planet and an
indicator of global change is the level of biodiversity. There is a
long history of attempts to define this concept precisely, but the
difficulty is that this concept has many dimensions. We will explore
the idea of deriving biodiversity starting from properties of
ecosystems, in particular normal, healthy competition between
species. We will introduce an old idea of Joel Cohen's, the notion of
competition graph corresponding to a food web, and study the number of
dimensions needed to account for competition using ideas from the
theory of vertex-edge graphs.
