Abstract
The last Quaternary ice age strongly influenced the distribution of most plants and
animals. Here I used genetics, ecological niche modeling and bioacoustics to understand
the possible historical patterns behind the current distribution of the Downy Woodpecker
(Picoides pubescens) in North America. Analyses of mtDNA sequences and seven
microsatellites loci suggest low genetic differentiation among populations (a maximum of
two genetic groups), however population structure is subtle. Ecological niche modeling
suggests several refugia SE of US, and some restricted areas east and west of the Rocky
Mountains with ecological suitable conditions for the species at 18-21 kya. The analysis
of the pik call suggested no geographic variation in the frequency and temporal variables
studied. It is likely that the Downy Woodpecker expanded and colonized northern North
America quickly after the LGM from a southern refugium
