Data from: The monophyly of Euparkeriidae (Reptilia: Archosauriformes) and the origins of Archosauria: a revision of Dorosuchus neoetus from the Mid-Triassic of Russia

Roland B. Sookias, Andrey G. Sennikov, David J. Gower & Richard J. Butler
Euparkeria capensis is resolved as the sister taxon to crown Archosauria in many cladistic phylogenies and provides a key outgroup which may approximate the ancestral archosaur morphology. Several other taxa have been referred to the family Euparkeriidae, but the monophyly of this taxon remains doubtful and largely untested. In order to test this monophyly, the archosauriform and putative euparkeriid Dorosuchus neoetus from the Mid-Triassic of Russia is reexamined in light of recent work on the...

Data from: A palaeoequatorial Ornithischian and new constraints on early dinosaur diversification

Paul M. Barrett, Richard J. Butler, Roland Mundil, Torsten M. Scheyer, Randall B. Irmis, Marcelo R. Sánchez-Villagra, R. B. Irmis, P. M. Barrett, R. J. Butler, M. R. Sanchez-Villagra, T. M. Scheyer & R. Mundil
Current characterizations of early dinosaur evolution are incomplete: existing palaeobiological and phylogenetic scenarios are based on a fossil record dominated by saurischians and the implications of the early ornithischian record are often overlooked. Moreover, the timings of deep phylogenetic divergences within Dinosauria are poorly constrained owing to the absence of a rigorous chronostratigraphical framework for key Late Triassic–Early Jurassic localities. A new dinosaur from the earliest Jurassic of the Venezuelan Andes is the first basal...

Data from: An SNP-based second-generation genetic map of Daphnia magna and its application to QTL analysis of phenotypic traits

Jarkko Routtu, Matthew D. Hall, Brian Albere, Christian Beisel, R. Daniel Bergeron, Anurag Chaturvedi, Jeong-Hyeon Choi, John Colbourne, Luc De Meester, Melissa T. Stephens, Claus-Peter Stelzer, Eleanne Solorzano, W. Kelley Thomas, Michael E. Pfrender & Dieter Ebert
Background: Although Daphnia is increasingly recognized as a model for ecological genomics and biomedical research, there is, as of yet, no high-resolution genetic map for the genus. Such a map would provide an important tool for mapping phenotypes and assembling the genome. Here we estimate the genome size of Daphnia magna and describe the construction of an SNP array based linkage map. We then test the suitability of the map for life history and behavioural...

Data from: Bayesian causal inference explains movement coordination to auditory beats

Mark T. Elliott, Alan M. Wing, Andrew E. Welchman, A. E. Welchman, M. T. Elliott & A. M. Wing
Many everyday skilled actions depend on moving in time with signals that are embedded in complex auditory streams (e.g. musical performance, dancing or simply holding a conversation). Such behaviour is apparently effortless; however, it is not known how humans combine auditory signals to support movement production and coordination. Here, we test how participants synchronize their movements when there are potentially conflicting auditory targets to guide their actions. Participants tapped their fingers in time with two...

Data from: How innovative are new drugs launched in the UK? A retrospective study of new drugs listed in the British National Formulary (BNF) 2001-2012

Derek J. Ward, Angharad Slade, Tracey Genus, Orsolina I. Martino & Andrew J. Stevens
Objectives: Innovative new drugs offer potential benefits to patients, healthcare systems, governments and the pharmaceutical industry. Recent data suggest annual numbers of new drugs launched in the UK have increased in recent years, and we sought to understand whether this represents increasing numbers of highly innovative drugs being made available or the introduction of increasing numbers of drugs with limited additional therapeutic value. Design and setting: Retrospective observational study of new drug entries in the...

Data from: Competition and constraint drove Cope's rule in the evolution of giant flying reptiles

Roger B. J. Benson, Rachel A. Frigot, Anjali Goswami, Brian Andres & Richard J. Butler
The pterosaurs, Mesozoic flying reptiles, attained wingspans of more than 10 m that greatly exceed the largest birds and challenge our understanding of size limits in flying animals. Pterosaurs have been used to illustrate Cope’s rule, the influential generalization that evolutionary lineages trend to increasingly large body sizes. However, unambiguous examples of Cope’s rule operating on extended timescales in large clades remain elusive, and the phylogenetic pattern and possible drivers of pterosaur gigantism are uncertain....

Data from: Basal dinosauriform and theropod dinosaurs from the middle-late Norian (Late Triassic) of Poland: implications for Triassic dinosaur evolution and distribution

Grzegorz Niedźwiedzki, Stephen L. Brusatte, Tomasz Sulej & Richard J. Butler
The rise of dinosaurs during the Triassic is a widely studied evolutionary radiation, but there are still many unanswered questions about early dinosaur evolution and biogeography that are hampered by an unevenly sampled Late Triassic fossil record. Although very common in western North America and parts of South America, dinosaur (and more basal dinosauriform) remains are relatively rare in the Upper Triassic deposits of Europe, making any new discoveries critically important. One of the most...

Data from: Taxonomy of the proterosuchid archosauriforms (Diapsida: Archosauromorpha) from the earliest Triassic of South Africa, and implications for the early archosauriform radiation

Martín D. Ezcurra & Richard J. Butler
Proterosuchidae is one of the first clades of Archosauriformes (archosaurs and closely related species) to appear in the fossil record, with the richest sample of the group coming from the Lystrosaurus Assemblage Zone (earliest Triassic) of South Africa. Four nominal proterosuchid species were described from South Africa during the twentieth century (Proterosuchus fergusi, Chasmatosaurus vanhoepeni, Chasmatosaurus alexanderi and Elaphrosuchus rubidgei), but interpretations of their taxonomy have been widely disparate. The most recent taxonomic revision concluded...

Ecological risk due to river flow alteration under climate and socioeconomic change scenarios

C.L.R. Laize, M.C. Acreman, C. Schneider, M.J. Dunbar, H.A. Houghton-Carr, M. Florke & D.M. Hannah
This dataset contains modelled outputs of the European river network modelled as 33,668 cells (5° longitude by 5° latitude). For each cell, modelled monthly flows were generated for an ensemble of tenscenarios for the 2050s and for the study baseline (naturalized flows for 1961 to 1990). Score classes are categorisation of flow alteration scenarios.

Data from: Metabolomic perfusate analysis during kidney machine perfusion: the pig provides an appropriate model for human studies

Jay Nath, Alison Guy, Thomas B. Smith, Mark Cobbold, Nicholas G. Inston, James Hodson, Daniel A. Tennant, Christian Ludwig & Andrew R. Ready
Introduction: Hypothermic machine perfusion offers great promise in kidney transplantation and experimental studies are needed to establish the optimal conditions for this to occur. Pig kidneys are considered to be a good model for this purpose and share many properties with human organs. However it is not established whether the metabolism of pig kidneys in such hypothermic hypoxic conditions is comparable to human organs. Methods: Standard criteria human (n = 12) and porcine (n =...
