Data from: Phylogeography of a marine insular endemic in the Atlantic Macaronesia: the Azorean barnacle, Megabalanus azoricus (Pilsbry, 1916)

The Azorean barnacle, Megabalanus azoricus (Pilsbry, 1916), is a Macaronesian endemic whose obscure taxonomy and the unknown relationships among forms inhabiting isolated Northern Atlantic oceanic islands is investigated by means of molecular analysis herein. Mitochondrial data from the 16S rRNA and COX1 genes support its current species status, tropical ancestry, and the taxonomic homogeneity throughout its distribution range. In contrast, at the intraspecific level and based on control region sequences, we detected an overall low...

Data from: Patterns of pollen dispersal in a small population of the Canarian endemic palm (Phoenix canariensis)

Isabel Saro, Juan J. Robledo-Arnuncio, Miguel A. González-Pérez & Pedro A. Sosa
The genetic diversity of small populations is greatly influenced by local dispersal patterns and genetic connectivity among populations, with pollen dispersal being the major component of gene flow in many plants species. Patterns of pollen dispersal, mating system parameters and spatial genetic structure were investigated in a small isolated population of the emblematic palm Phoenix canariensis in Gran Canaria island (Canary Islands). All adult palms present in the study population (n=182), as well as 616...

Data from: Ecological divergence combined with ancient allopatry in lizard populations from a small volcanic island

Nicolas M. Suárez, Jose Pestano & Richard P. Brown
Population divergence and speciation are often explained by geographical isolation, but may also be possible under high gene flow due to strong ecology-related differences in selection pressures. This study combines coalescent analyses of genetic data (11 microsatellite loci and 1 Kbp of mtDNA) and ecological modelling to examine the relative contributions of isolation and ecology to incipient speciation in the scincid lizard Chalcides sexlineatus within the volcanic island of Gran Canaria. Bayesian multispecies coalescent dating...

Data from: The history of the North African mitochondrial DNA haplogroup U6 gene flow into the African, Eurasian and American continents

Bernard Secher, Rosa Fregel, José M Larruga, Vicente M Cabrera, Phillip Endicott, José J Pestano & Ana M González
Background: Complete mitochondrial DNA (mtDNA) genome analyses have greatly improved the phylogeny and phylogeography of human mtDNA. Human mitochondrial DNA haplogroup U6 has been considered as a molecular signal of a Paleolithic return to North Africa of modern humans from southwestern Asia. Results: Using 230 complete sequences we have refined the U6 phylogeny, and improved the phylogeographic information by the analysis of 761 partial sequences. This approach provides chronological limits for its arrival to Africa,...
