The Convention on Biological Diversity (CBD) aims at the conservation of all three levels of biodiversity, i.e. ecosystems, species and genes. Genetic diversity represents evolutionary potential and is important for ecosystem functioning. Unfortunately, genetic diversity in natural populations is hardly considered in conservation strategies because it is difficult to measure and has been hypothesized to co-vary with species richness. This means that species richness is taken as a surrogate of genetic diversity in conservation planning,...

Data from: From incipient to substantial: evolution of placentotrophy in a phylum of aquatic colonial invertebrates

Andrew N. Ostrovsky
Matrotrophy has long been known in invertebrates, but it is still poorly understood and has never been reviewed. A striking example of matrotrophy (namely, placentotrophy) is provided by the Bryozoa, a medium-sized phylum of the aquatic colonial filter feeders. Here I report on an extensive anatomical study of placental analogues in 21 species of the bryozoan order Cheilostomata, offering the first review on matrotrophy among aquatic invertebrates. The first anatomical description of incipient placentotrophy in...

Data from: Geographical parthenogenesis and population genetic structure in the alpine species Ranunculus kuepferi (Ranunculaceae)

Anne-Caroline Cosendai, Johanna Wagner, Ursula Ladinig, Christoph Rosche & Elvira Hörandl
Geographical parthenogenesis describes the enigmatic phenomenon that asexual organisms have larger distribution areas than their sexual relatives, especially in previously glaciated areas. Classical models suggest temporary advantages to asexuality in colonization scenarios because of uniparental reproduction and clonality. We analyzed population genetic structure and self-fertility of the plant species Ranunculus kuepferi on 59 populations from the whole distribution area (European Alps, Apennines and Corsica). Amplified fragment length polymorphisms (AFLPs) and five microsatellite loci revealed individual...

Data from: The extreme disjunction between Beringia and Europe in Ranunculus glacialis s. l. (Ranunculaceae) does not coincide with the deepest genetic split – a story of the importance of temperate mountain ranges in arctic-alpine phylogeography

Michal Ronikier, Gerald M. Schneeweiss & Peter Schönswetter
The arctic–alpine Ranunculus glacialis s. l. is distributed in high-mountain ranges of temperate Europe and in the North, where it displays an extreme disjunction between the North Atlantic Arctic and Beringia. Based on comprehensive sampling and employing plastid and nuclear marker systems, we (i) test whether the European/Beringian disjunction correlates with the main evolutionary diversification, (ii) reconstruct the phylogeographic history in the Arctic and in temperate mountains and (iii) assess the susceptibility of arctic and...

Data from: Tales of the unexpected: Phylogeography of the arctic-alpine model plant Saxifraga oppositifolia (Saxifragaceae) revisited

Manuela Winkler, Andreas Tribsch, Gerald M. Schneeweiss, Sabine Brodbeck, Felix Gugerli, Rolf Holderegger, Richard J. Abbott & Peter Schönswetter
Arctic-alpine biota occupy enormous areas in the Arctic and the northern hemisphere mountain ranges, and have undergone major range shifts during their comparatively short history. The origins of individual arctic-alpine species remain largely unknown. In the case of the Purple saxifrage, Saxifraga oppositifolia, an important model for arctic-alpine plants, phylogeographic studies have remained inconclusive about early stages of the species’ spatiotemporal diversification, but have provided evidence for long-range colonization out of a presumed Beringian origin...

Data from: Approximate Bayesian computation for modular inference problems with many parameters: the example of migration rates

Simon Aeschbacher, Andreas Futschik & Mark A. Beaumont
We propose a two-step procedure for estimating multiple migration rates in an approximate Bayesian computation (ABC) framework, accounting for global nuisance parameters. The approach is not limited to migration, but generally of interest for inference problems with multiple parameters and a modular structure (e.g. independent sets of demes or loci). We condition on a known, but complex demographic model of a spatially subdivided population, motivated by the reintroduction of Alpine ibex (Capra ibex) into Switzerland....

Data from: Evolution of eye morphology and rhodopsin expression in the Drosophila melanogaster species subgroup

Nico Posnien, Corinna Hopfen, Maarten Hilbrant, Margarita Ramos-Womack, Sophie Murat, Anna Schönauer, Samantha L. Herbert, Maria D. S. Nunes, Saad Arif, Casper J. Breuker, Christian Schlötterer, Philipp Mitteroeker, Alistair P. McGregor & Philipp Mitteroecker
A striking diversity of compound eye size and shape has evolved among insects. The number of ommatidia and their size are major determinants of the visual sensitivity and acuity of the compound eye. Each ommatidium is composed of eight photoreceptor cells that facilitate the discrimination of different colours via the expression of various light sensitive Rhodopsin proteins. It follows that variation in eye size, shape, and opsin composition is likely to directly influence vision. We...
