- Abstract:
- The importance of prokaryotic diversity to ecosystem function is suspected but unknown. The extent of bacterial diversity has rendered conventional methods of estimating diversity inadequate for measuring changes in diversity in response to environmental stress. It has thus been impossible to test this hypothesis. We have developed a model based on species abundance distributions which can be used to quantify bacterial diversity (Curtis et al., 2002. PNAS, 99, 10494-10499). The bacterial species distribution is predicted to change from log-normal under circumstances where many factors act simultaneously to geometric when a single or few factors drive community structure e.g. reduction in water quality due to pollution. We will use our model to test whether lake trophic status and water quality are linked to the species abundance distribution and bacterial diversity.
