Why do tropical bird & avian-malaria communities vary from place to place?

In PNAS, @SabrinaMcnew et al. answered this by modeling diversity across Peru, based on years of field, lab, & museum work.

Generalized dissimilarity modeling (GDM) was key.

For both birds & avian malaria, *rainfall* had the strongest influence on species turnover.
