Morphological measurements of tree finches sampled on Floreana Island, Galápagos in 2004, 2005, 2006, 2008, 2010, 2012, 2013 and 2014. Techniques for measuring morphological variables are described in the associated manuscript. ‘Putative population’ refers to assignment based on morphology for exploratory analyses (see associated manuscript and supplementary material). ‘Cluster’ and ‘Membership Coefficient’ refers to population assignment based on analyses of microsatellite loci (using the program STRUCTURE)
