Figure 4From: Genetic and phenotypic characterization of a hybrid zone between polyandrous Northern and Wattled Jacanas in Western PanamaUnrooted parsimony tree for COI haplotypes of Jacana spinosa , J. jacana , and hybrids throughout their ranges. Black hatches indicate unobserved haplotypes. Note the lack of geographic structuring within species across distant geographic regions (e.g. Brazil, Argentina and Panama), and that all birds with a hybrid index score greater than 0.3 had spinosa haplotypes (see text).Back to article page
