Data from: Genotypic variation in a foundation tree (Populus tremula L.) explains community structure of associated epiphytes

Chantel Davies, Christopher J. Ellis, Glenn R. Iason & Richard A. Ennos
Community genetics hypothesizes that within a foundation species the genotype of an individual significantly influences the assemblage of dependent organisms. To assess whether these intra-specific genetic effects are ecologically important, it is required to compare their impact on dependent organisms with that attributable to environmental variation experienced over relevant spatial scales. We assessed bark epiphytes on 27 aspen (Populus tremula L.) genotypes grown in a randomized experimental array at two contrasting sites spanning the environmental...

Data from: Parasitism in early life: environmental conditions shape intra-brood variation in responses to infection

Hanna M. V. Granroth-Wilding, Sarah J. Burthe, Sue Lewis, Thomas E. Reed, Katherine A. Herborn, Mark A. Newell, Emi A. Takahashi, Francis Daunt & Emma J. A. Cunningham
Parasites play key ecological and evolutionary roles through the costs they impose on their host. In wild populations, the effect of parasitism is likely to vary considerably with environmental conditions, which may affect the availability of resources to hosts for defense. However, the interaction between parasitism and prevailing conditions is rarely quantified. In addition to environmental variation acting on hosts, individuals are likely to vary in their response to parasitism, and the combined effect of...

Data from: Selection history and epistatic interactions impact dynamics of adaptation to novel environmental stresses

Mato Lagator, Nick Colegrave & Paul Neve
In rapidly changing environments, selection history may impact the dynamics of adaptation. Mutations selected in one environment may result in pleiotropic fitness trade-offs in subsequent novel environments, slowing the rates of adaptation. Epistatic interactions between mutations selected in sequential stressful environments may slow or accelerate subsequent rates of adaptation, depending on the nature of that interaction. We explored the dynamics of adaptation during sequential exposure to herbicides with different modes of action in Chlamydomonas reinhardtii....

Data from: Cultural evolution of systematically structured behaviour in a non-human primate

Nicolas Claidière, Kenny Smith, Simon Kirby & Joël Fagot
Culture pervades human life and is at the origin of the success of our species. A wide range of other animals have culture too, but often in a limited form that does not complexify through the gradual accumulation of innovations. We developed a new paradigm to study cultural evolution in primates in order to better evaluate our closest relatives' cultural capacities. Previous studies using transmission chain experimental paradigms, in which the behavioural output of one...

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: The extent and genetic basis of phenotypic divergence in life history traits in Mimulus guttatus

Jannice Friedman, Alex D. Twyford, John H. Willis & Benjamin K. Blackman
Differential natural selection acting on populations in contrasting environments often results in adaptive divergence in multivariate phenotypes. Multivariate trait divergence across populations could be caused by selection on pleiotropic alleles or through many independent loci with trait-specific effects. Here, we assess patterns of association between a suite of traits contributing to life history divergence in the common monkeyflower, Mimulus guttatus, and examine the genetic architecture underlying these correlations. A common garden survey of 74 populations...

Data from: Spontaneous mutation accumulation in multiple strains of the green alga, Chlamydomonas reinhardtii

Andrew D. Morgan, Rob W. Ness, Peter David Keightley & Nick Colegrave
Estimates of mutational parameters, such as the average fitness effect of a new mutation and the rate at which new genetic variation for fitness is created by mutation, are important for the understanding of many biological processes. However, the causes of interspecific variation in mutational parameters and the extent to which they vary within species remain largely unknown. We maintained multiple strains of the unicellular eukaryote Chlamydomonas reinhardtii, for approximately 1000 generations under relaxed selection...

Data from: Determining the phylogenetic and phylogeographic origin of highly pathogenic avian influenza (H7N3) in Mexico

Lu Lu, Samantha J. Lycett & Andrew J. Leigh Brown
Highly pathogenic (HP) avian influenza virus (AIV) H7N3 outbreaks occurred 3 times in the Americas in the past 10 years and caused severe economic loss in the affected regions. In June/July 2012, new HP H7N3 outbreaks occurred at commercial farms in Jalisco, Mexico. Outbreaks continued to be identified in neighbouring states in Mexico till August 2013. To explore the origin of this outbreak, time resolved phylogenetic trees were generated from the eight segments of full-length...
