Whole-genome sequencing projects are increasingly populating the tree of life and
characterizing biodiversity 1 , 2 , 3 – 4 . Sparse taxon sampling has previously been proposed to …

Using cline fitting and divergence population genetics, we tested a prediction of Haldane's
rule: autosomal alleles should introgress more than z-linked alleles or mitochondrial …

One of the most novel foraging strategies in Neotropical birds is army-ant-following, in which
birds prey upon arthropods and small vertebrates flushed from the forest floor by swarm …

Background Theoretical work suggests that data from multiple nuclear loci provide better
estimates of population genetic parameters than do single loci, but just how many loci are …

In air-breathing vertebrates, the physiologically optimal blood-O 2 affinity is jointly determined
by the prevailing partial pressure of atmospheric O 2 , the efficacy of pulmonary O 2 transfer…

Quantifying the role of gene flow during the divergence of closely related species is crucial
to understanding the process of speciation. We collected DNA sequence data from 20 loci (…

The Willet (Tringa semipalmata; Scolopacidae) is composed of 2 morphologically and
vocally distinct subspecies with broadly disjunct breeding distributions in North America. …

Although theoretical models predict that the structure of a hybrid zone can change under a
variety of scenarios, only a few empirical studies of hybrid zones have unequivocally …

In this study, we explore the long-standing issue of how many loci are needed to infer
accurate phylogenetic relationships, and whether loci with particular attributes (eg, parsimony …

Phylogenetic and population genetic analyses of DNA sequence data from 10 nuclear loci
were used to test species divergence hypotheses within Passerina buntings, with special …
