Data from: Morphometric analysis and taxonomic revision of Anisopteromalus Ruschka (Hymenoptera: Chalcidoidea: Pteromalidae) – an integrative approach

Hannes Baur, Yvonne Kranz-Baltensperger, Astrid Cruaud, Jean-Yves Rasplus, Alexander V. Timokhov & Vladimir E. Gokhman
We use an integrative taxonomic approach to revise the genus Anisopteromalus. In particular, we apply multivariate ratio analysis (MRA), a rather new statistical method based on principal component analysis (PCA) and linear discriminant analysis (LDA), to numerous body measurements and combine the data with those from our molecular analysis of Cytb and ITS2 genetic markers (on a subset of species) and all available published data on morphology, karyology, behavior, host associations, and geographic distribution. We...

Data from: Phylogeography and demographic history of two widespread Indo-Pacific mudskippers (Gobiidae: Periophthalmus)

Gianluca Polgar, Lorenzo Zane, Massimiliano Babbucci, Federica Barbisan, Tomaso Patarnello, Lukas Rüber & Chiara Papetti
This study provides a first description of the phylogeographic patterns and evolutionary history of two species of the mudskipper genus Periophthalmus. These amphibious gobies are distributed throughout the whole Indo-Pacific region and Atlantic coast of Africa, in peritidal habitats of soft-bottom coastal ecosystems. Three sequence datasets of two widely distributed species, Periophthalmus argentilineatus and P. kalolo, were obtained by amplifying and sequencing two mtDNA markers (D-loop and 16S rDNA) and the nDNA rag1 region. The...

Ancient mitogenomics clarifies radiation of extinct Mascarene giant tortoises (Cylindraspis spp.)

Christian Kehlmaier, Eva Graciá, Patrick D. Campbell, Margaretha D. Hofmeyr, Silke Schweiger, Albert Martínez-Silvestre, Walter Joyce & Uwe Fritz
The five extinct giant tortoises of the genus Cylindraspis belong to the most iconic species of the enigmatic fauna of the Mascarene Islands that went largely extinct after the discovery of the islands. To resolve the phylogeny and biogeography of Cylindraspis, we analysed a data set of 45 mitogenomes that includes all lineages of extant tortoises and eight near-complete sequences of all Mascarene species extracted from historic and subfossil material. Cylindraspis is an ancient lineage...

Data from: Genetic structure and effective population sizes in European red deer (Cervus elaphus) at a continental scale: insights from microsatellite DNA

Frank E. Zachos, Alain C. Frantz, Ralph Kuehn, Sabine Bertouille, Marc Colyn, Magdalena Niedzialkowska, Javier Pérez-González, Anna Skog, Nikica Šprem & Marie-Christine Flamand
We analysed more than 600 red deer (Cervus elaphus) from large parts of its European distribution range at 13 microsatellite loci, presenting the first continent-wide study of this species using nuclear markers. Populations were clearly differentiated (overall FST = 0.166, Jost’s Dest = 0.385), and the BAPS clustering algorithm yielded mainly geographically limited and adjacent genetic units. When forced into only three genetic clusters our data set produced a very similar geographic pattern as previously...

Data from: Sexual dimorphism in shells of Cochlostoma septemspirale (Caenogastropoda, Cyclophoroidea, Diplommatinidae, Cochlostomatinae)

Fabian Reichenbach, Hannes Baur & Eike Neubert
Sexual dimorphisms in shell-bearing snails expressed by characteristic traits of their respective shells would offer the possibility for a lot of studies about gender distribution in populations, species, etc. In this study, the seven main shell characters of the snail Cochlostoma septemspirale were measured in both sexes: (1) height and (2) width of the shell, (3) height and (4) width of the aperture, (5) width of the last whorl, (6) rib density on the last...

Bernhard Misof, Shanlin Liu, Karen Meusemann, Ralph S. Peters, Alexander Donath, Christoph Mayer, Paul B. Frandsen, Jessica Ware, Tomas Flouri, Rolf G. Beutel, Oliver Niehuis, Malte Petersen, Fernando Izquierdo-Carrasco, Torsten Wappler, Jes Rust, Andre J. Aberer, Ulrike Aspöck, Horst Aspöck, Daniela Bartel, Alexander Blanke, Simon Berger, Alexander Böhm, Thomas Buckley, Brett Calcott, Junqing Chen … & Xin Zhou
Insects are the most speciose group of animals, but the phylogenetic relationships of many major lineages remain unresolved. We inferred the phylogeny of insects from 1478 protein-coding genes. Phylogenomic analyses of nucleotide and amino acid sequences, with site-specific nucleotide or domain-specific amino acid substitution models, produced statistically robust and congruent results resolving previously controversial phylogenetic relations hips. We dated the origin of insects to the Early Ordovician [~479 million years ago (Ma)], of insect flight...

Data from: Multiple independent colonizations into the Congo Basin during the continental radiation of African Mastacembelus spiny eels

Julia J. Day, Antonie Fages, Katherine J. Brown, Emmanuel J. Vreven, Melanie L. J. Stiassny, Roger Bills, John P. Friel, Lukas Rüber & Antoine Fages
Aim: There has been recent interest in the origin and assembly of continental biotas based on densely sampled species-level clades, however, studies from African freshwaters are few so that the commonality of macroevolutionary patterns and processes among continental clades remain to be tested. Within the Afrotropics, the Congo Basin contains the highest diversity of riverine fishes, yet it is unclear how this fauna was assembled. To address this, and the diversification dynamics of a continental...

Data from: Barcoding snakeheads (Teleostei, Channidae) revisited: discovering greater species diversity and resolving perpetuated taxonomic confusions

Cecilia Conte-Grand, Ralf Britz, Neelesh Dahanukar, Rajeev Raghavan, Rohan Pethiyagoda, Hoek Hui Tan, Renny Kurnia Hadiaty, Norsham S. Yaakob, Lukas Rüber & Heok Hui Tan
Snakehead fishes of the family Channidae are predatory freshwater teleosts from Africa and Asia comprising 38 valid species. Snakeheads are important food fishes (aquaculture, live food trade) and have been introduced widely with several species becoming highly invasive. A channid barcode library was recently assembled by Serrao and co-workers to better detect and identify potential and established invasive snakehead species outside their native range. Comparing our own recent phylogenetic results of this taxonomically confusing group...

Data from: A new dimension in documenting new species: high-detail imaging for myriapod taxonomy and first 3D cybertype of a new millipede species (Diplopoda, Julida, Julidae)

Nesrine Akkari, Henrik Enghoff & Brian D. Metscher
We review the state-of-the-art approaches currently applied in myriapod taxonomy, and we describe, for the first time, a new species of millipede (Ommatoiulus avatar n. sp., family Julidae) using high-resolution X-ray microtomography (microCT) as a substantive adjunct to traditional morphological examination. We present 3D models of the holotype and paratype specimens and discuss the potential of this non-destructive technique in documenting new species of millipedes and other organisms. The microCT data have been uploaded to...

Data from: Mitochondrial phylogenomics of Hemiptera reveals adaptive innovations driving the diversification of true bugs

Hu Li, , Eric G. Chapman, Daniel Burkhardt, Fan Song, Pei Jiang, Jinpeng Liu, Xuguo Zhou, Wanzhi Cai & John M. Leavengood
Hemiptera, the largest non-holometabolous order of insects, represents ~7% of metazoan diversity. With extraordinary life histories and highly specialized morphological adaptations, hemipterans have exploited diverse habitats and food sources through ~300 million years of evolution. To elucidate the phylogeny and evolutionary history of Hemiptera, we carried out the most comprehensive mitogenomics analysis on the richest taxon sampling to date covering all the suborders and infraorders, including 34 newly sequenced and 94 published mitogenomes. With optimized...

Data from: Plio-Pleistocene phylogeography of the Southeast Asian Blue Panchax killifish, Aplocheilus panchax

Samantha V. Beck, Gary R. Carvalho, Axel Barlow, Lukas Rüber, Heok Hui Tan, Estu Nugroho, Daisy Wowor, Siti Azizah Mohd Nor, Fabian Herder, Zainal A. Muchlisin & Mark De Bruyn
The complex climatic and geological history of Southeast Asia has shaped this region’s high biodiversity. In particular, sea level fluctuations associated with repeated glacial cycles during the Pleistocene both facilitated, and limited, connectivity between populations. In this study, we used data from two mitochondrial and three anonymous nuclear markers to determine whether a fresh/brackish water killifish, Aplocheilus panchax, Hamilton, 1822, could be used to further understand how climatic oscillations and associated sea level fluctuations have...

Data from: Late Triassic (Julian) conodont biostratigraphy of a transition from reefal limestones to deep-water environments on the Cimmerian terranes (Taurus mountains, southern Turkey)

Yanlong Chen & Alexander Lukeneder
Sections at Aşağiyaylabel and Yukariyaylabel, Taurus Mountains, southern Turkey, provide a rare opportunity to investigate conodont faunas in detail across a reef to slope transition. Intensive sampling of limestone beds (wackestones to packstones) through approximately 3 m at these locations has led to the recognition of a new lower Carnian (Julian 1/2) conodont fauna within the Kartoz and Kasimlar formations. Members of the subfamilies Paragondolellinae and Pseudofurnishiinae are recognized. The genus Kraussodontus is reported for...

Data from: Indication for selfing in geographically separated populations and evidence for Pleistocene survival within the Alps: the case of Cylindrus obtusus (Pulmonata: Helicidae)

Luise Kruckenhauser, Elisabeth Haring, Barbara Tautscher, Luis Cadahía, Laura Zopp, Michael Duda, Josef Harl & Helmut Sattmann
Background: Cylindrus obtusus is one of the most prominent endemic snail species of the Eastern Alps. It is restricted to alpine meadows and calcareous rocky habitats above 1500 m. Its genital tract shows a peculiar intraspecific difference: in the eastern populations the two mucus glands associated with the love dart sac are highly variable, while almost no variation was observed in the western populations. This raises the question whether the mode and success of reproduction...

Data from: A phylogenetic analysis of the megadiverse Chalcidoidea (Hymenoptera)

John M. Heraty, Roger A. Burks, Astrid Cruaud, Gary A. P. Gibson, Johan Liljeblad, James Munro, Jean-Yves Rasplus, Gerard Delvare, Petr Janšta, Alex Gumovsky, John Huber, James B. Woolley, Lars Krogmann, Steve Heydon, Andrew Polaszek, Stefan Schmidt, D. Chris Darling, Michael W. Gates, Jason Mottern, Elizabeth Murray, Ana Dal Molin, Serguei Triapitsyn, Hannes Baur, John D. Pinto, Simon Van Noort … & Matthew Yoder
Chalcidoidea (Hymenoptera) is extremely diverse with an estimated 500 000 species. We present the first phylogenetic analysis of the superfamily based on both morphological and molecular data. A web-based, systematics workbench mx was used to score 945 character states illustrated by 648 figures for 233 morphological characters for a total of 66 645 observations for 300 taxa. The matrix covers 22 chalcidoid families recognized herein and includes 268 genera within 78 of 83 subfamilies. Morphological...

Data from: A new species of the paper wasp genus Polistes (Hymenoptera, Vespidae, Polistinae) in Europe revealed by morphometrics and molecular analyses

Rainer Neumeyer, Hannes Baur, Gaston-Denis Guex & Christophe Praz
We combine multivariate ratio analysis (MRA) of body measurements and analyses of mitochondrial and nuclear data to examine the status of several species of European paper wasps (Polistes Latreille, 1802) closely related to P. gallicus. Our analyses unambiguously reveal the presence of a cryptic species in Europe, as two distinct species can be recognized in what has hitherto been considered Polistes bischoffi Weyrauch, 1937. One species is almost as light coloured as P. gallicus, and...

Data from: Ancestral remnants or peripheral segregates? Phylogenetic relationships of two narrowly endemic Euphrasia species (Orobanchaceae) from the eastern European Alps

Da Pan, Peter Schönswetter, Tim Moser, Ernst Vitek & Gerald M. Schneeweiss
Endemism in mountain ranges is considered to be the result of a number of factors, including restriction to refugia during Pleistocene climate fluctuations. However, isolation in glacial refugia cannot explain the origin of narrowly endemic taxa restricted to formerly heavily glaciated areas. Here, we investigate the phylogeny of two narrowly endemic species, Euphrasia inopinata and E. sinuata (Orobanchaceae), found exclusively in formerly heavily glaciated areas of the eastern European Alps. As both species are diploid...

Data from: Natural and anthropogenic influences on the population structure of white-tailed eagles in the Carpathian Basin and Central Europe

Edina Nemesházi, Szilvia Kövér, Frank E. Zachos, Zoltán Horváth, Gábor Tihanyi, Attila Mórocz, Tibor Mikuska, István Hám, Ivan Literák, Suvi Ponnikas, Tadeusz Mizera & Krisztián Szabó
European populations of the white-tailed eagle (Haliaeetus albicilla) suffered a drastic decline during the 20th century. In many countries, only a few dozen breeding pairs survived or the species disappeared completely. By today, the populations have recovered, naturally or through restocking (e.g. in Scotland or the Czech Republic). In the Carpathian Basin, which is now a stronghold in southern Europe for the species in the southern part of the distribution range with more than 500...

Data from: Evolutionary divergence in life history traits among populations of the Lake Malawi cichlid fish Astatotilapia calliptera

Paul J. Parsons, Jon R. Bridle, Lukas Rüber & Martin J. Genner
During the early stages of adaptive radiation, populations diverge in life history traits such as egg size and growth rates, in addition to eco-morphological and behavioral characteristics. However, there are few studies of life history divergence within ongoing adaptive radiations. Here, we studied Astatotilapia calliptera, a maternal mouthbrooding cichlid fish within the Lake Malawi haplochromine radiation. This species occupies a rich diversity of habitats, including the main body of Lake Malawi, as well as peripheral...

Data from: Using genetic tools to estimate the prevalence of non-native red deer (Cervus elaphus) in a Western European population

Alain C. Frantz, Frank E. Zachos, Sabine Bertouille, Marie-Christine Eloy, Marc Colyn & Marie-Christine Flamand
Game species like the red deer have been subjected to anthropogenic impacts for centuries. Translocations are often carried out—sometimes illegally—not only for sporting purposes, but also to increase trophy quality, reduce inbreeding, or mitigate bottlenecks after excessive persecution. Apart from the blurring of large-scale genetic structure, translocations without adequate quarantine measure risk introducing pathogens into potentially immunologically naïve populations. It is therefore important to understand the frequency of clandestine translocations. Identification of non-autochthonous animals and...

Data from: Oncological and surgical outcome after treatment of pelvic sarcomas

Stephan Puchner, Philipp T. Funovics, Christoph Böhler, Alexandra Kaider, Christoph Stihsen, Gerhard M. Hobusch, Joannis Panotopoulos, Reinhard Windhager & Stephan E. Puchner
Background and Objectives. Treatment of pelvic tumors remains challenging due to complex anatomy, poor oncological outcome and high complication rates. We sought to investigate the long-term oncological and surgical outcome of these patients. Methods. Between 1980 and 2012, 147 patients underwent surgical treatment for pelvic sarcoma. Histological diagnosis was Chondrosarcoma in 54, Ewing's Sarcoma/PNET in 37, Osterosarcoma in 32 and others in 24 patients. Statistical analysis for the evaluation of oncological and surgical outcome was...

Data from: Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)

Heather R. L. Lerner, Les Christidis, Anita Gamauf, Carole Griffiths, Elisabeth Haring, Christopher J. Huddleston, Sonia Kabra, Annett Kocum, Meade Krosby, Kirsti Kvaloy, David Mindell, Pamela Rasmussen, Nils Rov, Rachel Wadleigh, Michael Wink & Jan Ove Gjershaug
We present a phylogeny of all booted eagles (38 extant and one extinct species) based on analysis of published sequences from seven loci. We find molecular support for five major clades within the booted eagles: Nisaetus (10 species), Spizaetus (4 species), Clanga (3 species), Hieraaetus (6 species) and Aquila (11 species), requiring generic changes for 14 taxa. Additionally, we recommend that the Long-crested Eagle (Lophaetus occipitalis) and the Black Eagle (Ictinaetus malaiensis) remain in their...

Data from: Plant interactions shape pollination networks via nonadditive effects

Gianalberto Losapio, Miguel A. Fortuna, Jordi Bascompte, Bernhard Schmid, Richard Michalet, Rainer Neumeyer, Leopoldo Castro, Pierfilippo Cerretti, Christoph Germann, Jean-Paul Haenni, Seraina Klopfstein, Francisco Javier Ortiz-Sánchez, Adrian C. Pont, Pascal Rousse, Jürg Schmid, Daniele Sommaggio & Christian Schöb
Plants grow in communities where they interact with other plants and with other living organisms such as pollinators. On the one hand, studies of plant–plant interactions rarely consider how plants interact with other trophic levels such as pollinators. On the other, studies of plant–animal interactions rarely deal with interactions within trophic levels such as plant–plant competition and facilitation. Thus, to what degree plant interactions affect biodiversity and ecological networks across trophic levels is poorly understood....

Genomic signals of admixture and reinforcement between two closely related species of European sepsid flies

Martin Kapun, Athene Giesen, Wolf U Blanckenhorn, Martin A Schäfer, Kentaro K Shimizu, Rie Shimizu-Inatsugi, Bernhard Misof, Oliver Niehuis, Lars Podsiadlowski, Heidi E L Liescher & Simon Aeschbacher
Interspecific gene flow by hybridization may weaken species barriers and adaptive divergence, but can also initiate reinforcement of reproductive isolation through natural and sexual selection. However, the extent of interspecific gene flow and its consequences for the initiation and maintenance of species barriers in natural systems remain poorly understood. We first applied coalescence simulations and approximate Bayesian calculations based on microsatellite data to infer the yet unknown demographic history of the two closely related European...

Data from: Citizen science reveals unexpected continental-scale evolutionary change in a model organism

Jonathan Silvertown, Laurence Cook, Robert Cameron, Mike Dodd, Kevin McConway, Jenny Worthington, Peter Skelton, Christian Anton, Oliver Bossdorf, Bruno Baur, Menno Schilthuizen, Benoît Fontaine, Helmut Sattmann, Giorgio Bertorelle, Maria Correia, Cristina Oliveira, Beata Pokryszko, Małgorzata Ożgo, Arturs Stalažs, Eoin Gill, Üllar Rammul, Péter Sólymos, Zoltan Féher & Xavier Juan
Organisms provide some of the most sensitive indicators of climate change and evolutionary responses are becoming apparent in species with short generation times. Large datasets on genetic polymorphism that can provide an historical benchmark against which to test for recent evolutionary responses are very rare, but an exception is found in the brown-lipped banded snail (Cepaea nemoralis). This species is sensitive to its thermal environment and exhibits several polymorphisms of shell colour and banding pattern...

Data from: Conservation action based on threatened species capture taxonomic and phylogenetic richness in breeding and wintering populations of Central Asian birds

Manuel Schweizer, Raffael Ayé, Roman Kashkarov & Tobias Roth
Although phylogenetic diversity has been suggested to be relevant from a conservation point of view, its role is still limited in applied nature conservation. Recently, the practice of investing conservation resources based on threatened species was identified as a reason for the slow integration of phylogenetic diversity in nature conservation planning. One of the main arguments is based on the observation that threatened species are not evenly distributed over the phylogenetic tree. However this argument...
