Data from: Complex life cycles: why refrain from growth before reproduction in the adult niche?

Daniel P. Benesh, James C. Chubb & Geoff A. Parker
Organisms with complex life cycles occupy distinct niches as larvae and adults. One presumed advantage of this is the ability to exploit different resources successively throughout ontogeny. Various taxa, however, have evolved non-feeding, non-growing adult stages. We show theoretically that this counterintuitive 'no-growth' strategy is favored when the optimal larval size is greater than or equal to the optimal adult size for reproduction. We empirically investigated this in a group of parasitic worms (helminths). Helminths...

Data from: Genome patterns of selection and introgression of haplotypes in natural populations of the house mouse (Mus musculus)

Fabian Staubach, Anna Lorenc, Philipp W. Messer, Kun Tang, Dmitri A. Petrov & Diethard Tautz
General parameters of selection, such as the frequency and strength of positive selection in natural populations or the role of introgression are still insufficiently understood. The house mouse (Mus musculus) is a particularly well-suited model system to approach such questions, since it has a defined history of splits into subspecies and populations and extensive genome information is available. We have used high-density single nucleotide polymorphism (SNP) typing arrays to assess genomic patterns of positive selection...

Data from: The pipid root

Adam J. Bewick, Frédéric J. J. Chain, Joseph Heled & Ben J. Evans
The estimation of phylogenetic relationships is an essential component of understanding evolution. Accurate phylogenetic estimation is difficult, however, when internodes are short and old, when genealogical discordance is common due to large ancestral effective population sizes or ancestral population structure, and when homoplasy is prevalent. Inference of divergence times is also hampered by unknown and uneven rates of evolution, the incomplete fossil record, uncertainty in relationships between fossil and extant lineages, and uncertainty in the...

Data from: Exploring local immunological adaptation of two stickleback ecotypes by experimental infection and transcriptome-wide digital gene expression analysis

Tobias L. Lenz, Christophe Eizaguirre, Björn Rotter, Martin Kalbe & Manfred Milinski
Understanding the extent of local adaptation in natural populations and the mechanisms that allow individuals to adapt to their native environment is a major avenue in molecular ecology research. Evidence for the frequent occurrence of diverging ecotypes in species that inhabit multiple ecological habitats is accumulating, but experimental approaches to understanding the biological pathways as well as the underlying genetic mechanisms are still rare. Parasites are invoked as one of the major selective forces driving...
