Data from: Competence increases survival during stress in Streptococcus pneumoniae.

Daniel J P Engelmoer & Daniel E Rozen
Horizontal gene transfer mediated by transformation is of central importance in bacterial evolution. However, numerous questions remain about the maintenance of processes that underlie transformation. Most hypotheses for the benefits of transformation focus on what bacteria might do with DNA, but ignore the important fact that transformation is subsumed within the broader process of competence. Accordingly, the apparent benefits of transformation might rely less on recombination than on other potential benefits associated with the broader...

Data from: Developmental plasticity, morphological variation and evolvability: a multilevel analysis of morphometric integration in the shape of compound leaves

Chris P. Klingenberg, Sascha Duttke, Simon Whelan & Minsung Kim
The structure of compound leaves provides flexibility for morphological change by variation in the shapes, sizes and arrangement of leaflets. Here we conduct a multilevel analysis of shape variation in compound leaves to explore the developmental plasticity and evolutionary potential that are the basis of diversification in leaf shape. We use the methods of geometric morphometrics to study the shapes of individual leaflets and whole leaves in 20 taxa of Potentilla (sensu lato). A newly...

Data from: A computational analysis of locomotor anatomy and body mass evolution in Allosauroidea (Dinosauria Theropoda)

Karl T. Bates, Roger B. J. Benson & Peter L. Falkingham
We investigate whether musculoskeletal anatomy and three-dimensional (3-D) body proportions were modified during the evolution of large (>6000 kg) body size in Allosauroidea (Dinosauria Theropoda). Three adaptations for maintaining locomotor performance at large body size, related to muscle leverage, mass, and body proportions, are tested and all are unsupported in this analysis. Predictions from 3-D musculoskeletal models of medium-sized (Allosaurus) and large-bodied (Acrocanthosaurus) allosauroids suggest that muscle leverage scaled close to isometry, well below the...

Data from: Genetic variation for antibiotic persistence in Escherichia coli

Balint Stewart & Daniel E Rozen
Bacterial persistence describes a heterogenous response to antibiotics in clonal populations of bacteria due to phenotypic variation within the population, with a small proportion of cells surviving treatment even at very high concentrations of drug. The aim of this study was to determine whether different natural isolates of E. coli, selected at random from a collection representing the spectrum of genetic diversity in the species, generate different fractions of persister cells. Despite comparable minimum inhibitory...

Data from: Citizen science reveals unexpected continental-scale evolutionary change in a model organism

Jonathan Silvertown, Laurence Cook, Robert Cameron, Mike Dodd, Kevin McConway, Jenny Worthington, Peter Skelton, Christian Anton, Oliver Bossdorf, Bruno Baur, Menno Schilthuizen, Benoît Fontaine, Helmut Sattmann, Giorgio Bertorelle, Maria Correia, Cristina Oliveira, Beata Pokryszko, Małgorzata Ożgo, Arturs Stalažs, Eoin Gill, Üllar Rammul, Péter Sólymos, Zoltan Féher & Xavier Juan
Organisms provide some of the most sensitive indicators of climate change and evolutionary responses are becoming apparent in species with short generation times. Large datasets on genetic polymorphism that can provide an historical benchmark against which to test for recent evolutionary responses are very rare, but an exception is found in the brown-lipped banded snail (Cepaea nemoralis). This species is sensitive to its thermal environment and exhibits several polymorphisms of shell colour and banding pattern...

Data from: Genotype-dependent responses to levels of sibling competition over maternal resources in mice

Reinmar Hager, James M. Cheverud & Jason B. Wolf
Research on phenotypic plasticity has often focused on how a given genotype responds to changing physical environments. However, for many species the social environment plays an equally important role due to competition for resources. During early development, the level of competition for limited resources will often depend critically on the number of siblings. Therefore, competition among siblings should drive the evolution of genes that allow flexible responses to realized levels of competition and maternal resource...

Data from: Pervasive genetic integration directs the evolution of human skull shape

Neus Martínez-Abadías, Mireia Esparza, Torstein Sjøvold, Rolando González-José, Mauro Santos, Miquel Hernández & Christian Peter Klingenberg
It has long been unclear whether the different derived cranial traits of modern humans evolved independently in response to separate selection pressures or whether they resulted from the inherent morphological integration throughout the skull. In a novel approach to this issue, we combine evolutionary quantitative genetics and geometric morphometrics to analyze genetic and phenotypic integration in human skull shape. We measured human skulls in the ossuary of Hallstatt (Austria), which offer a unique opportunity because...

Data from: Comparative phylogeography reveals a shared impact of Pleistocene environmental change in shaping genetic diversity within nine Anopheles mosquito species across the Indo-Burma biodiversity hotspot

Katy Morgan, Samantha M. O’Loughlin, Bin Chen, Yvonne-Marie Linton, Damrongpan Thongwat, Pradya Somboon, Mun Yik Fong, Roger Butlin, Robert Verity, Anil Prakash, Thaung Hlaing, Simone Nambanya, Duong Socheat, Trung Ho Dinh & Catherine Walton
Southeast Asia is one of the world’s richest regions in terms of biodiversity. An understanding of the distribution of diversity and the factors shaping it is lacking, yet essential for identifying conservation priorities for the region’s highly threatened biodiversity. Here we take a large scale comparative approach, combining data from nine forest associated Anopheles mosquito species and using statistical phylogeographic methods to disentangle the effects of environmental history, species specific ecology, and random coalescent effects....
