Data from: The origin of modern frogs (Neobatrachia) was accompanied by acceleration in mitochondrial and nuclear substitution rates

Iker Irisarri, Diego San Mauro, Federico Abascal, Annemarie Ohler, Miguel Vences & Rafael Zardoya
BACKGROUND: Understanding the causes underlying heterogeneity of molecular evolutionary rates among lineages is a long-standing and central question in evolutionary biology. Although several earlier studies showed that modern frogs (Neobatrachia) experienced an acceleration of mitochondrial gene substitution rates compared to non-neobatrachian relatives, no further characterization of this phenomenon was attempted. To gain new insights on this topic, we sequenced the complete mitochondrial genomes and nine nuclear loci of one pelobatoid (Pelodytes punctatus) and five neobatrachians,...

Data from: Independent sources of condition dependency and multiple pathways determine a composite trait: lessons from carotenoid-based plumage colouration

Cristina Romero-Díaz, Heinz Richner, Fernando Granado-Lorencio, Barbara Tschirren, Patrick Fitze & C. Romero-Diaz
Many color ornaments are composite traits consisting of at least four components, which themselves may be more complex, determined by independent evolutionary pathways, and potentially being under different environmental control. To date, little evidence exists that several different components of color elaboration are condition-dependent and no direct evidence exists that different ornamental components are affected by different sources of variation. For example, in carotenoid-based plumage coloration, one of the best-known condition-dependent ornaments, color elaboration stems...

Data from: Experimental design in phylogenetics: testing predictions from expected information

Diego San Mauro, David J. Gower, James A. Cotton, Rafael Zardoya, Mark Wilkinson & Tim Massingham
Taxon and character sampling is central to phylogenetic experimental design yet we lack general rules. Goldman introduced a method to construct efficient sampling designs in phylogenetics, based on the calculation of expected Fisher information given a probabilistic model of sequence evolution. The considerable potential of this approach remains largely unexplored. In an earlier study, we applied Goldman’s method to a problem in the phylogenetics of caecilian amphibians and made an a priori evaluation and testable...

Data from: The ecological and genetic basis of convergent thick-lipped phenotypes in cichlid fishes

Marco Colombo, Eveline T. Diepeveen, Moritz Muschick, M. Emilia Santos, Adrian Indermaur, Nicolas Boileau, Marta Barluenga & Walter Salzburger
The evolution of convergent phenotypes is one of the most interesting outcomes of replicate adaptive radiations. Remarkable cases of convergence involve the thick-lipped phenotype found across cichlid species flocks in the East African Great Lakes. Unlike most other convergent forms in cichlids, which are restricted to East Africa, the thick-lipped phenotype also occurs elsewhere, e.g. in the Central American Midas Cichlid assemblage. Here we use an ecological genomic approach to study the function, the evolution...

Data from: Phylogeny and biogeography of the Poecilia sphenops species complex (Actinopterygii, Poeciliidae) in Central America

Fernando Alda, Ruth G. Reinar, Ignacio Doadrio, Eldredge Bermingham & Ruth G. Reina
We inferred the phylogenetic relationships among members of the Poecilia sphenops species complex to resolve the colonization process and radiation of this group in Central America. We analyzed 2550 base pairs (bp) of mitocondrial DNA (mtDNA), including ATP synthase 6 and 8, cytochrome oxidase subunit I and NADH dehydrogenase subunit 2 genes, and 906 bp of the nuclear S7 ribosomal protein of 86 ingroup individuals from 61 localities spanning most of its distribution from Mexico...

Data from: Molecular phylogenetics, species diversity, and biogeography of the Andean lizards Proctoporus (Squamata: Gymnophthalmidae)

Noemi Goicoechea, Jose M. Padial, Juan C. Chaparro, Santiago Castroviejo-Fisher & Ignacio De La Riva
The family Gymnophthalmidae comprises ca. 220 described species of Neotropical lizards distributed from southern Mexico to Argentina. It includes 36 genera, among them Proctoporus, which contains six currently recognized species occurring across the yungas forests and wet montane grasslands of the Amazonian versant of the Andes from central Peru to central Bolivia. Here, we investigate the phylogenetic relationships and species limits of Proctoporus and closely related taxa by analyzing 2121 base pairs of mitochondrial (12S,...

Data from: Fractal geometry of a complex plumage trait reveals bird's quality

Lorenzo Pérez-Rodríguez, Roger Jovani & François Mougeot
Animal coloration is key in natural and sexual selection, playing significant roles in intra- and interspecific communication because of its linkage to individual behaviour, genetics and physiology. Simple animal traits such as the area or the colour intensity of homogeneous patches have been profusely studied. More complex patterns are widespread in nature, but they escape our understanding because their variation is difficult to capture effectively by standard, simple measures. Here, we used fractal geometry to...

Data from: Genetic assessment of population structure and connectivity in the threatened Mediterranean coral Astroides calycularis (Scleractinia, Dendrophylliidae) at different spatial scales

Pilar Casado-Amezúa, Stefano Goffredo, José Templado & Annie Machordom
Understanding dispersal patterns, population structure and connectivity among populations is helpful in the management and conservation of threatened species. Molecular markers are useful tools as indirect estimators of these characteristics. In this study we assess the population genetic structure of the endemic Mediterranean coral Astroides calycularis in the Alboran Sea at local and regional scales, and at three localities outside of this basin. Bayesian clustering methods, traditional F-statistics and Dest statistics were used to determine...
