Surrogates

Ecologists commonly rely on proxies or surrogates to measure change in ecosystems; metrics of biodiversity that are assumed to be representative of the broader state of a particular ecosystem. While convenient, this approach has been criticised for being overly simplistic. Much of my current research involves evaluating the empirical basis of surrogate ecology, using long-term datasets from the Lindenmayer lab.
