Data from: Female responses to experimental removal of sexual selection in Drosophila melanogaster

Paolo Innocenti, Ilona Flis & Edward H. Morrow
Background: Despite the common assumption that multiple mating should in general be favored in males, but not in females, to date there is no consensus on the general impact of multiple mating on female fitness. Notably, very little is known about the genetic and physiological features underlying the female response to sexual selection pressures. By combining an experimental evolution approach with genomic techniques, we investigated the effects of single and multiple matings on female fecundity...

Data from: Emergent global patterns of ecosystem structure and function from a mechanistic General Ecosystem Model

Michael Brian James Harfoot, Tim Newbold, Derek P. Tittensor, Stephen Emmott, Jon Hutton, Vassily Lyutsarev, Matthew J. Smith, Jorn P. W. Scharlemann & Drew W. Purves
Anthropogenic activities are causing widespread degradation of ecosystems worldwide, threatening the ecosystem services upon which all human life depends. Improved understanding of this degradation is urgently needed to improve avoidance and mitigation measures. One tool to assist these efforts is predictive models of ecosystem structure and function that are mechanistic: based on fundamental ecological principles. Here we present the first mechanistic General Ecosystem Model (GEM) of ecosystem structure and function that is both global, and...

Data from: Between-sex genetic covariance constrains the evolution of sexual dimorphism in Drosophila melanogaster

Fiona C. Ingleby, Paolo Innocenti, Howard D. Rundle & E. H. Morrow
Males and females share much of their genome, and as a result, intralocus sexual conflict is generated when selection on a shared trait differs between the sexes. This conflict can be partially or entirely resolved via the evolution of sex-specific genetic variation that allows each sex to approach, or possibly achieve, its optimum phenotype, thereby generating sexual dimorphism. However, shared genetic variation between the sexes can impose constraints on the independent expression of a shared...

Data from: Using social parasitism to test reproductive skew models in a primitively eusocial wasp

Jonathan P. Green, Michael A. Cant & Jeremy Field
Remarkable variation exists in the distribution of reproduction (skew) among members of cooperatively breeding groups, both within and between species. Reproductive skew theory has provided an important framework for understanding this variation. In the primitively eusocial Hymenoptera, two models have been routinely tested: concessions models, which assume complete control of reproduction by a dominant individual, and tug-of-war models, which assume on-going competition among group members over reproduction. Current data provide little support for either model,...
