Data from: Decisive datasets in phylogenomics: lessons from studies on the phylogenetic relationships of primarily wingless insects

Phylogenetic relationships of the primarily wingless insects are still considered unresolved. Even the most comprehensive phylogenomic studies that addressed this question did not yield congruent results. In order to get a grip on these problems, we here analyzed the sources of incongruence in these phylogenomic studies using an extended transcriptome dataset.Our analyses showed that unevenly distributed missing data can be severely misleading by inflating node support despite the absence of phylogenetic signal. In consequence, only...

Data from: Species distribution models contribute to determine the effect of climate and interspecific interactions in moving hybrid zones

Jan O. Engler, Dennis Rödder, Ortwin Elle, Axel Hochkirch & Jean Secondi
Climate is a major factor delimiting species’ distributions. However, biotic interactions may also be prominent in shaping geographical ranges, especially for parapatric species forming hybrid zones. Determining the relative effect of each factor and their interaction of the contact zone location has been difficult due to the lack of broad scale environmental data. Recent developments in species distribution modelling (SDM) now allow disentangling the relative contributions of climate and species’ interactions in hybrid zones and...

Data from: Isolation and characterization of nine polymorphic microsatellite markers for the deep-sea shrimp Nematocarcinus lanceopes (Crustacea: Decapoda: Caridea)

BACKGROUND: The shrimp Nematocarcinus lanceopes Bate, 1888 is found in the deep sea around Antarctica and sub-Antarctic islands. Previous studies on mitochondrial data and species distribution models provided evidence for a homogenous circum-Antarctic population of N. lanceopes. However, to analyze the fine-scale population genetic structure and to examine influences of abiotic environmental conditions on population composition and genetic diversity, a set of fast evolving nuclear microsatellite markers is required. FINDINGS: We report the isolation and...

Data from: Notes on the acoustic repertoire of Melanophryniscus klappenbachi Prigioni & Langone, 2000

Meike Kurth, David Hörnes, Sascha Esser & Dennis Rödder
The genus Melanophryniscus Gallardo, 1961 currently comprises 25 recognized species (Frost 2012) arranged in three (Cruz & Caramaschi 2003) to four species groups (Cespedez & Motte 2001, quoted by Maneyro et al. 2008) on the basis of morphological characters. The Melanophryniscus stelzneri species group currently contains nine species, i.e. M. atroluteus (Miranda-Ribeiro, 1920), M. cupreuscapularis Céspedez & Alvarez, 2000, M. dorsalis (Mertens, 1933), M. fulvoguttatus (Mertens, 1937), M. klappenbachi Prigioni & Langone, 2000, M. krauczuki...

Data from: The impact of paralogy on phylogenomic studies - a case study on annelid relationships

Torsten H. Struck
Phylogenomic studies based on hundreds of genes derived from expressed sequence tags libraries are increasingly used to reveal the phylogeny of taxa. A prerequisite for these studies is the assignment of genes into clusters of orthologous sequences. Sophisticated methods of orthology prediction are used in such analyses, but it is rarely assessed whether paralogous sequences have been erroneously grouped together as orthologous sequences after the prediction, and whether this had an impact on the phylogenetic...
