Data from: Differences in caste dimorphism among three hornet species (Hymenoptera: Vespidae): forewing size, shape and allometryAdrien Perrard, Claire Villemant, James M. Carpenter & Michel Baylac
Caste shape dimorphism (CShD) has previously been studied in wasps through comparison of different body parts, originating from different imaginal discs. Using geometric morphometrics with a new protocol for measuring wings of pinned specimens from natural history collections, we tested CShD of three hornet species in an organ developed from a single imaginal disc: the forewing. Gaussian Mixture Models retrieved most castes and species levels confirming that caste is an important component of wing variations...
Single-access keys are a major tool for biologists who need to identify specimens. The construction process of these keys is particularly complex (especially if the input dataset is large) so having an automatic single-access key generation tool is essential. As part of the European project ViBRANT, our aim was to develop such a tool as a web service, thus allowing end-users to integrate it directly into their workflow. IKey+generates single-access keys on demand, for single...
Predicting how and when adaptive evolution might rescue species from global change, and integrating this process into tools of biodiversity forecasting, has now become an urgent task. Here we explored whether recent population trends of species can be explained by their past rate of niche evolution, which can be inferred from increasingly available phylogenetic and niche data. We examined the assemblage of 409 European bird species for which estimates of demographic trends between 1970 and...
Data from: High frequency echolocation, ear morphology, and the marine–freshwater transition: a comparative study of extant and extinct toothed whalesCarolina S. Gutstein, Constanza P. Figueroa-Bravo, Nicholas D. Pyenson, Roberto E. Yury-Yañez, Mario A. Cozzuol & Mauricio Canals
This study compares the bony ear morphology of freshwater and marine odontocetes (toothed whales). Odontocetes are unique among marine mammals in two important respects: 1) they use echolocation; 2) at least three lineages have independently evolved obligate freshwater habits from marine ancestries. Freshwater odontocetes include the so-called “river dolphins,” a paraphyletic group that each evolved convergent external morphological characters that distinguish them from oceanic dolphins (Delphinoidea). In addition to their convergent external morphology, “river dolphins”...
Data from: The origin of modern frogs (Neobatrachia) was accompanied by acceleration in mitochondrial and nuclear substitution ratesIker 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,...
