Data from: Synopsis and taxonomic revision of three genera in the snake tribe Sonorini

Delimiting species is a crucial goal of integrative biology, and yet can be misled by homoplasy and high levels of morphological variation. The snake tribe Sonorini contains three genera that have long confounded taxonomists: Chilomeniscus, Chionactis and Sonora. Dynamic colour evolution in this group, including rampant geographic variation in colour and colour polymorphism, has led to a chaotic taxonomy. We used mitochondrial and high-throughput nuclear data (ddRADseq) and complete taxonomic sampling of each genus to...

Data from: Adaptive changes in sexual signaling in response to urbanization

Wouter Halfwerk, Michiel Blaas, Lars Kramer, Nadia Hijner, Paula A. Trillo, Ximena E. Bernal, Rachel A. Page, Sandra Goutte, Michael J. Ryan & Jacintha Ellers
Urbanization can cause species to adjust their sexual displays, as the effectiveness of mating signals is impacted by environmental conditions. Despite many examples showing that mating signals in urban conditions differ from those in rural conditions, we do not know whether these differences provide a combined reproductive and survival benefit to the urban phenotype. Here we show that male tĂșngara frogs have increased the conspicuousness of their calls, which is under strong sexual and natural...

Data from: The complete mitochondrial genome of the sea urchin, Echinometra sp. EZ

Remi N. Ketchum, Melissa B. DeBiasse, Joseph F. Ryan, John A. Burt & Adam M. Reitzel
The complete mitogenome of Echinometra sp. EZ has been described and fully annotated in this study. Cytochrome subunit one phylogenetic analysis of six Echinometra species confirms that our sample is E. sp. EZ. The mitogenome is 15,698 bp in length and contains 13 protein-coding genes, 22 tRNAs, 2 rRNAs, and a non-coding region with an identical organization to other Echinoidea. The E. sp. EZ mitogenome shared ~99.1% identity to the published Echinometra mathaei mitogenome, differing...

Data from: Differential effect of selection against LINE retrotransposons among vertebrates inferred from whole-genome data and demographic modeling

Alexander T Xue, Robert P. Ruggiero, Michael J. Hickerson & Stéphane Boissinot
Variation in LINE composition is one of the major determinants for the substantial size and structural differences among vertebrate genomes. In particular, the larger genomes of mammals are characterized by hundreds of thousands of copies from a single LINE clade, L1, whereas nonmammalian vertebrates possess a much greater diversity of LINEs, yet with orders of magnitude less in copy number. It has been proposed that such variation in copy number among vertebrates is due to...
