Modelling avian α-diversity in the landuse transformation systems of Indonesia

In preparation of Focus 3 analysis, there is need to model one taxonomic group in more detail. Birds are ideal because they can be validated with data from plots other than the core plots. Which environmental variables determine local avian species richness in the landuse transformation systems of Indonesia? How can environmental predictor variables be combined into a statistical regression model to predict avian species richness? Can avian species richness be predicted by environmental variables in a sufficiently precise manner? What is the effect of landuse system transformation on avian species richness?
