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: Visuo-spatial cueing in children with differential reading and spelling profiles

Chiara Banfi, Ferenc Kemény, Melanie Gangl, Gerd Schulte-Körne, Kristina Moll & Karin Landerl
Dyslexia has been claimed to be causally related to deficits in visuo-spatial attention. In particular, inefficient shifting of visual attention during spatial cueing paradigms is assumed to be associated with problems in graphemic parsing during sublexical reading. The current study investigated visuo-spatial attention performance in an exogenous cueing paradigm in a large sample (N = 191) of third and fourth graders with different reading and spelling profiles (controls, isolated reading deficit, isolated spelling deficit, combined...

Data from: Molecular investigation of genetic assimilation during the rapid adaptive radiations of East African cichlid fishes

Helen M. Gunter, Ralf F. Schneider, Immanuel Karner, Christian Sturmbauer & Axel Meyer
Adaptive radiations are characterized by adaptive diversification intertwined with rapid speciation within a lineage resulting in many ecologically specialized, phenotypically diverse species. It has been proposed that adaptive radiations can originate from ancestral lineages with pronounced phenotypic plasticity in adaptive traits, facilitating ecologically-driven phenotypic diversification that is ultimately fixed through genetic assimilation of gene regulatory regions. This study aimed to investigate how phenotypic plasticity is reflected in gene expression patterns in the trophic apparatus of...

Data from: Shifting barriers and phenotypic diversification by hybridisation

Kristina M. Sefc, Karin Mattersdorfer, Angelika Ziegelbecker, Nina Neuhüttler, Oliver Steiner, Walter Goessler & Stephan Koblmüller
The establishment of hybrid taxa relies on reproductive isolation from the parental forms, typically achieved by ecological differentiation. Here, we present an alternative mechanism, in which shifts in the strength and location of dispersal barriers facilitate diversification by hybridisation. Our case study concerns the highly diverse, stenotopic rock-dwelling cichlids of the African Great Lakes, many of which display geographic colour pattern variation. The littoral habitat of these fish has repeatedly been restructured in the course...

Data from: High fidelity: extra-pair fertilisations in eight Charadrius plover species are not associated with parental relatedness or social mating system

Kathryn H. Maher, Luke J. Eberhart-Phillips, András Kosztolányi, Natalie Dos Remedios, María Cristina Carmona-Isunza, Medardo Cruz-López, Sama Zefania, James J. H. St Clair, Monif AlRashidi, Michael A. Weston, Martín A. Serrano-Meneses, Oliver Krüger, Joseph I. Hoffmann, Tamás Székely, Terry Burke, Clemens Küpper & Joseph I. Hoffman
Extra-pair paternity is a common reproductive strategy in many bird species. However, it remains unclear why extra-pair paternity occurs and why it varies among species and populations. Plovers (Charadrius spp.) exhibit considerable variation in reproductive behaviour and ecology, making them excellent models to investigate the evolution of social and genetic mating systems. We investigated inter- and intra-specific patterns of extra-pair parentage and evaluated three major hypotheses explaining extra-pair paternity using a comparative approach based on...

Data from: Cuticular hydrocarbon cues of immune-challenged workers elicit immune activation in honeybee queens

Javier Hernandez Lopez, Ulrike Riessberger-Gallé, Karl Crailsheim, Wolfgang Schühly & Wolfgang Schuehly
Recently, evidence has shown that variations in the cuticular hydrocarbons (CHCs) profile allow healthy honeybees to identify diseased nestmates, eliciting agonistic responses in the former. Here, we determined whether these ‘immunologic cues’ emitted by diseased nestmates were only detected by workers, who consequently took hygienic measures and excluded these individuals from the colony, or whether queens were also able to detect these cues and respond accordingly. Healthy honeybee queens were exposed to (i) healthy, (ii)...
