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: The effect of plant identity and the level of plant decay on molecular gut content analysis in a herbivorous soil insect

Corinna Wallinger, Karin Staudacher, Nikolaus Schallhart, Eva Peter, Phillipp Dresch, Anita Juen, Michael Traugott & Philipp Dresch
Plant roots represent an important food source for soil-dwelling animals, but tracking herbivore food choices below-ground is difficult. Here, we present an optimized PCR assay for the detection of plant DNA in the guts of invertebrates, using general plant primers targeting the trnT-F chloroplast DNA region. Based on this assay, we assessed the influence of plant identity on the detectability of ingested plant DNA in Agriotes click beetle larvae. Six different plant species were fed...

Data from: DNA-based analysis of regurgitates: a noninvasive approach to examine the diet of invertebrate consumers

Thomas Waldner & Michael Traugott
DNA-based gut content analysis has become an important tool for unravelling feeding interactions in invertebrate communities under natural conditions. It usually implies killing of the consumer and extracting the DNA from its food, either using the whole animal or its dissected gut. This post-mortem approach, however, is not suitable for investigating the diet of rare or protected species and also prohibits tracking individual dietary preferences as each consumer can provide trophic information only once. Moreover,...

Data from: Pleistocene survival on central Alpine nunataks: genetic evidence from the jumping bristletail Machilis pallida

Gregor A. Wachter, Wolfgang Arthofer, Thomas Dejaco, Lukas J. Rinnhofer, Florian M. Steiner & Birgit C. Schlick-Steiner
Mechanisms of survival during the Pleistocene glaciation periods have been studied for more than a century. Until now, molecular studies that confirmed animal survival on Alpine nunataks, i.e., ice-free summits surrounded by glaciers, were restricted to peripheral areas. Here, we search for molecular signatures of inner-Alpine survival of the narrow-endemic and putatively parthenogenetic Alpine jumping bristletail Machilis pallida combining mitochondrial and AFLP data from its three known populations. The mitochondrial data indicate survival on both...
