Figure 4 in Endorsing Darwin: global biogeography of the epipelagic goose barnacles Lepas spp. (Cirripedia, Lepadomorpha) proves cryptic speciation
Figure 4. Comparsion of mitochondrial single locus phylogenies based on PhyMl and MrBayes. All major groupings are retrieved from both loci. The faster evolving COI gene provides more intra-group resolution. Bootstrapping values are given above branches; posterior probabilities are given below branches.
Figure 2 in Endorsing Darwin: global biogeography of the epipelagic goose barnacles Lepas spp. (Cirripedia, Lepadomorpha) proves cryptic speciation
Figure 2. Initial phylogeny based on three genes (18S, 16S, and COI) from a subset of samples from the major oceans (PAUP*, re-confirmed with PhyML and MrBayes). A split in subtypes is found in Lepas anatifera and Lepas australis. The red arrows indicate 'outliers' in L. anatifera and Lepas pectinata. In L. anatifera, these were later found to belong to a global group, whereas in L. pectinata no obvious biogeographic subgroup was found.

Cryptic speciation in the Warbling Vireo (Vireo gilvus)
<p><span>Eastern (<i>Vireo gilvus gilvus</i>) and western (<i>V. g. swainsoni</i>) forms of the Warbling Vireo have essentially allopatric breeding ranges across north-central North America, but come into contact in central Alberta, Canada. In 1986, Jon Barlow presented preliminary morphological and song evidence suggesting that the Warbling Vireo complex might comprise more than one valid species. However, to date Barlow's suggestion is supported by only limited DNA evidence, demonstration of molt and migration differences between the taxa, and anecdotal accounts of differences in song, morphology, plumage, and ecology. We analyzed variation in both mitochondrial and nuclear DNA in birds from Alberta and surrounding areas to determine the levels of genetic differentiation and hybridization occurring in the contact zone, and whether the two taxa warrant recognition as separate biological species. Our analyses reveal that Warbling Vireos in Alberta and the surrounding areas are separated into two well-defined, genetically-differentiated, and monophyletic clades corresponding to previously-recognized taxonomic groups. The two taxa come into contact in a narrow (~85 km) zone in Barrhead County, northwest of Edmonton, Alberta. They show evidence of limited hybridization. The distinct genetic differences are maintained in the contact zone, where individuals of the two taxa may occupy neighboring territories. Differences in spring arrival dates, molt schedules and migration routes indicate that a migratory divide may play an important role in reproductive isolation. We suggest that the two taxa are distinct cryptic species: an eastern form, <i>Vireo gilvus, </i>and a western form, <i>Vireo swainsoni</i>.</span></p>
