Data from: Efficiency of lift production in flapping and gliding flight of swifts

Per Henningsson, Anders Hedenström & Richard J. Bomphrey
Many flying animals use both flapping and gliding flight as part of their routine behaviour. These two kinematic patterns impose conflicting requirements on wing design for aerodynamic efficiency and, in the absence of extreme morphing, wings cannot be optimised for both flight modes. In gliding flight, the wing experiences uniform incident flow and the optimal shape is a high aspect ratio wing with an elliptical planform. In flapping flight, on the other hand, the wing...

Data from: Social chromosome variants differentially affect queen determination and the survival of workers in the fire ant Solenopsis invicta

Séverine D. Buechel, Yannick Wurm & Laurent Keller
Intraspecific variation in social organization is common, yet the underlying causes are rarely known. An exception is the fire ant Solenopsis invicta in which the existence of two distinct forms of social colony organization is under the control of the two variants of a pair of social chromosomes, SB and Sb. Colonies containing exclusively SB/SB workers accept only one single queen and she must be SB/SB. By contrast, when colonies contain more than 10% of...

Data from: Molecular footprints of the Holocene retreat of dwarf birch in Britain

Nian Wang, James S. Borrell, William J. A. Bodles, Ana Kuttapitiya, Richard A. Nicholes, Richard J. A. Buggs, Anasuya Kuttapitiya & Richard A. Nichols
Past reproductive interactions among incompletely isolated species may leave behind a trail of introgressed alleles, shedding light on historical range movements. Betula pubescens is a widespread native tetraploid tree species in Britain, occupying habitats intermediate to those of its native diploid relatives, B. pendula and B. nana. Genotyping 1134 trees from the three species at 12 microsatellite loci we found evidence of introgression from both diploid species into B. pubescens, despite the ploidy difference. Surprisingly,...

Data from: Multi-serotype pneumococcal nasopharyngeal carriage prevalence in vaccine naïve Nepalese children, assessed using molecular serotyping.

Rama Kandasamy, Meeru Gurung, Anushil Thapa, Susan Ndimah, Neelam Adhikari, David R. Murdoch, Dominic F. Kelly, Denise E. Waldron, Katherine A. Gould, Stephen Thorson, Shrijana Shrestha, Jason Hinds & Andrew J. Pollard
Invasive pneumococcal disease is one of the major causes of death in young children in resource poor countries. Nasopharyngeal carriage studies provide insight into the local prevalence of circulating pneumococcal serotypes. There are very few data on the concurrent carriage of multiple pneumococcal serotypes. This study aimed to identify the prevalence and serotype distribution of pneumococci carried in the nasopharynx of young healthy Nepalese children prior to the introduction of a pneumococcal conjugate vaccine using...

Data from: New quantitative approaches reveal the spatial preference of nuclear compartments in mammalian fibroblasts

David J. Weston, Richard A. Russell, Elizabeth Batty, Kirsten Jensen, David A. Stephens, Niall M. Adams & Paul S. Freemont
The nuclei of higher eukaryotic cells display compartmentalization and certain nuclear compartments have been shown to follow a degree of spatial organization. To date, the study of nuclear organization has often involved simple quantitative procedures that struggle with both the irregularity of the nuclear boundary and the problem of handling replicate images. Such studies typically focus on inter-object distance, rather than spatial location within the nucleus. The concern of this paper is the spatial preference...

Data from: C, N, and P fertilization in an Amazonian rainforest support stoichiometric dissimilarity as a driver of litter diversity effects on decomposition

Sandra Barantal, Heidy Schimann, Nathalie Fromin & Stephan Hättenschwiler
Plant leaf litter generally decomposes faster as a group of different species than when individual species decompose alone, but underlying mechanisms of these diversity effects remain poorly understood. Because resource C : N : P stoichiometry (i.e. the ratios of these key elements) exhibits strong control on consumers, we supposed that stoichiometric dissimilarity of litter mixtures (i.e. the divergence in C : N : P ratios among species) improves resource complementarity to decomposers leading to...

Data from: Input-dependent frequency modulation of cortical gamma oscillations shapes spatial synchronization and enables phase coding

Eric Lowet, Mark Roberts, Avgis Hadjipapas, Alina Peter, Jan Van Der Eerden & Peter De Weerd
Fine-scale temporal organization of cortical activity in the gamma range (~25–80Hz) may play a significant role in information processing, for example by neural grouping (‘binding’) and phase coding. Recent experimental studies have shown that the precise frequency of gamma oscillations varies with input drive (e.g. visual contrast) and that it can differ among nearby cortical locations. This has challenged theories assuming widespread gamma synchronization at a fixed common frequency. In the present study, we investigated...
