![]() ![]() This finding is not consistent with a model of increasing genetic diversity with decreasing latitude. Thirdly, I examined variation in genetic differentiation between two populations in 60 codistributed Neotropical landbirds. All species were sampled in southern Belize and central Panama, and I found that the net nucleotide divergence (DA) spanned two orders of magnitude (0.00%-0.085%). ![]() Species of frugivores and nectivores had significantly lower DA values than species of insectivores, and in a subsample of 19 species with population-level sampling I found that populations of frugivores and nectivores were significantly more likely to show genetic signals of population expansion than populations of insectivores. These results suggest that foraging ecology plays a fundamentally import role in determining diversification patterns of neotropical birds.
