Data from: Sampling bias and the fossil record of planktonic foraminifera on land and in the deep seaGraeme T. Lloyd, Paul N. Pearson, Jeremy R. Young & Andrew B. Smith
Large-scale trends in planktonic foraminiferal diversity have so far been based on utilization of synoptic biostratigraphic range charts. Although this approach ensures the taxonomic consistency and quality of the data being used, it takes no formal account of any sampling biases that might exist in the fossil record. We demonstrate that the occurrence data of planktonic foraminifera, as recorded in the primary literature, are strongly biased by sampling. We do this by demonstrating that raw...
Data from: A review of Western Amblyscelio and Baryconus (Hymenoptera: Platygastroidea, Platygastridae)Ovidiu Alin Popovici, Lubomir Masner, David G. Notton & Mariana Popovici
The European species of the genera Amblyscelio and Baryconus are reviewed and revised based on morphological data. Females of Amblyscelio striaticeps Kieffer, 1913 and Baryconus graeffei (Kieffer, 1908) are described and the ovipositor of Amblyscelio is illustrated for the first time. The monotypic genus Amblyscelio was previously known only from a single male specimen. Baryconus graeffei is confirmed as a distinct species, while B. orbus Kononova, 2008 is recognized as a junior subjective synonym of...
Flies are one of four superradiations of insects (along with beetles, wasps, and moths) that account for the majority of animal life on Earth. Diptera includes species known for their ubiquity (Musca domestica house fly), their role as pests (Anopheles gambiae malaria mosquito), and their value as model organisms across the biological sciences (Drosophila melanogaster). A resolved phylogeny for flies provides a framework for genomic, developmental, and evolutionary studies by facilitating comparisons across model organisms,...
Taxon and character sampling is central to phylogenetic experimental design yet we lack general rules. Goldman introduced a method to construct efficient sampling designs in phylogenetics, based on the calculation of expected Fisher information given a probabilistic model of sequence evolution. The considerable potential of this approach remains largely unexplored. In an earlier study, we applied Goldman’s method to a problem in the phylogenetics of caecilian amphibians and made an a priori evaluation and testable...
Determining the relationships among the major groups of cellular life is important for understanding the evolution of biological diversity, but is difficult given the enormous time spans involved. In the textbook 'three domains' tree based on informational genes, eukaryotes and Archaea share a common ancestor to the exclusion of Bacteria. However, some phylogenetic analyses of the same data have placed eukaryotes within the Archaea, as the nearest relatives of different archaeal lineages. We compared the...
Data from: Lessons learned from microsatellite development for non-model organisms using 454 pyrosequencingCorine Schoebel, Sabine Brodbeck, Dominique Buehler, Carolina Cornejo, Jyoti Gajurel, Hanna Hartikainen, Daniela Keller, Marie Leys, Štěpánka Říčanová, Gernot Segelbacher, Silke Werth, Daniela Csencsics & C.

Microsatellites, also known as simple sequence repeats (SSRs), are among the most commonly used marker types in evolutionary and ecological studies. Next Generation Sequencing techniques such as 454 pyrosequencing allow the rapid development of microsatellite markers in nonmodel organisms. 454 pyrosequencing is a straightforward approach to develop a high number of microsatellite markers. Therefore, developing microsatellites using 454 pyrosequencing has become the method of choice for marker development. Here, we describe a user friendly way...
