Paper on the distribution of Acorn Woodpeckers in Colombia

A manuscript co-authored with friend and colleague, Ben Freeman, was published yesterday in PLoS ONE. In this manuscript, we study the distribution of Acorn Woodpecker (Melanerpes formicivorus) in South America, which is restricted to Colombia.


The distribution of Acorn Woodpecker (Melanerpes formicivorus). Interestingly, its distribution is restricted to the Colombian Andes in South America. In this paper, we use a niche-modelling approach to investigate the abiotic and biotic factors that influence this species’ distribution.

Using a niche-modelling approach, we find evidence that the presence of Colombian Oak (Quercus humboldtii), the lone species of oak in South America, improves the predictive abilities of niche models.


Ecological niche models constructed using only abiotic variables (A, D), only the presence of Quercus oaks (B, E), and a combined data set of abiotic variables and the presence of Quercus oaks (C,F).
