Biogeographic diversification of Eranthis (Ranunculaceae) reflects the geological history of the three great Asian plateaus

Kun-Li Xiang, Andrey S. Erst, Jian Yang, Huan-Wen Peng, Rosa Del C. Ortiz, Florian Jabbour, Tatyana V. Erst & Wei Wang
The evolutionary history of organisms with poor dispersal abilities usually parallels geological events. Collisions of the Indian and Arabian plates with Eurasia greatly changed Asian topography and affected regional and global climate as well as biotic evolution. However, the geological evolution of Asia related to these two collisions remains debated. Here, we used Eranthis, an angiosperm genus with poor seed dispersal ability and a discontinuous distribution across Eurasia , to shed light on the orogenesis...

Data from: Coalescence times, life history traits and conservation concerns: an example from four coastal shark species from the Indo-Pacific

Pierre Lesturgie, Serge Planes & Stefano Mona
Dispersal abilities play a crucial role in shaping the extent of population genetic structure, with more mobile species being panmictic over large geographic ranges and less mobile ones organized in meta-populations exchanging migrants to different degrees. In turn, population structure directly influences the coalescence pattern of the sampled lineages, but the consequences on the estimated variation of the effective population size (Ne) over time obtained by means of unstructureddemographic models remain poorly understood. However, this...

Hard to catch: experimental evidence supports evasive mimicry

Erika Páez V, Janne K. Valkonnen, Keith R. Willmott, Pável Matos-Maraví, Marianne Elias & Johanna Mappes
Most research on aposematism has focused on chemically defended prey, but the signaling difficulty of capture remains poorly explored. Similar to classical Batesian and Müllerian mimicry related to distastefulness, such ‘evasive aposematism' may also lead to convergence in warning colours, known as evasive mimicry. A prime candidate group for evasive mimicry areAdelphabutterflies, which are agile insects and show remarkable colour pattern convergence. We tested the ability of naive blue tits to learn to avoid and...

Focused Ion Beam tomography on fossilized osteocytes

Yara Haridy, Markus Osenberg, André Hilger, Ingo Manke, Donald Davesne & Florian Witzmann
Osteocytes play a central role in bone metabolism in extant vertebrates, but their evolutionary history is poorly understood. Therefore osteocyte lacunae microstructure of fossil bone was studied on the nanometer scale by means of focused ion beam tomography (FIB). A osteostracan and a “placoderm” were imaged, the earliest groups with cellular bone, and secondary osteons respectively. To visualize and characterize the early bone composition via the morphology and distribution of osteocyte lacunae, thereby imaging the...

Phenological data for the article: Phenotypic plasticity drives phenological changes in a Mediterranean blue tit population

Juliette Biquet, Suzanne Bonamour, Pierre De Villemereuil, Christophe De Franceschi & Céline Teplitsky
Earlier phenology induced by climate change, such as the passerines' breeding time, is observed in many natural populations. Understanding the nature of such changes is key to predict the responses of wild populations to climate change. Genetic changes have been rarely investigated for laying date, though it has been shown to be heritable and under directional selection, suggesting that the trait could evolve. In a Corsican blue tit population, the birds' laying date has significantly...

Adaptive evolution of flight in Morpho butterflies

Camille Le Roy, Dario Amadori, Samuel Charberet, Jaap Windt, Florian Muijres, Violaine Llaurens & Vincent Debat
The diversity of flying animals suggests that countless combinations of flight morphologies and behaviors have evolved with specific lifestyles, thereby exploiting diverse aerodynamic mechanisms. How morphology, flight behavior and aerodynamic properties together diversify with contrasting ecology remains to be elucidated. We studied the adaptive co-divergence in wing shape, flight behavior and aerodynamic efficiency among Morpho butterflies living in different forest strata, by combining high-speed videography in the field with morphometric analyses and aerodynamic modelling. By...

Alignement and phylogenetic tree of 106 Lepidoptera

Charline Pinna, Florence Piron-Prunier & Marianne Elias
We used both published and de novo sequences from one mitochondrial gene and seven nuclear genes, representing a total length of 7433 bp to infer a molecular phylogeny for 106 lepidopteran species. Müllerian mimicry is a positive interspecific interaction, whereby co-occurring defended prey species share a common aposematic signal. In Lepidoptera, aposematic species typically harbour conspicuous opaque wing colour patterns with convergent optical properties among co-mimetic species. Surprisingly, some aposematic mimetic species have partially transparent...

Measuring phylogenetic information of incomplete sequence data

Tae-Kun Seo, Olivier Gascuel & Jeffrey Thorne
Widely used approaches for extracting phylogenetic information from aligned sets of molecular sequences rely upon probabilistic models of nucleotide substitution or amino-acid replacement. The phylogenetic information that can be extracted depends on the number of columns in the sequence alignment and will be decreased when the alignment contains gaps due to insertion or deletion events. Motivated by the measurement of information loss, we suggest assessment of the Effective Sequence Length (ESL) of an aligned data...
