Data from: Bayesian adaptive Markov Chain Monte Carlo estimation of genetic parameters

Boby Mathew, Andrea M. Bauer, Petri Koistinen, Tobias C. Reetz, Jens Léon & Mikko J. Sillanpää
Accurate and fast estimation of genetic parameters that underlie quantitative traits using mixed linear models with additive and dominance effects is of great importance in both natural and breeding populations. Here we propose a new fast adaptive Markov Chain Monte Carlo (MCMC) sampling algorithm for the estimation of genetic parameters in the linear mixed model with several random effects. In the learning phase of our algorithm, we use the hybrid Gibbs sampler to learn the...

Data from: Genetic and phenotypic variation in juvenile development in relation to temperature and developmental pathway in a geometrid moth

Sami M. Kivelä, Panu Välimäki & Maarit I. Mäenpää
Life histories show genetic population-level variation due to spatial variation in selection pressures. Phenotypic plasticity in life histories is also common, facilitating fine-tuning of the phenotype in relation to the prevailing selection regime. In multivoltine (≥ 2 generations / year) insects, individuals following alternative developmental pathways (diapause / direct development) experience different selection regimes. We studied the genetic and phenotypic components of juvenile development in Cabera exanthemata (Lepidoptera: Geometridae) in a factorial split-brood experiment. F2...

Data from: Comparative genomics of chemosensory protein genes reveals rapid evolution and positive selection in ant-specific duplicates

Jonna Kulmuni, Yannick Wurm & Pekka Pamilo
Gene duplications can have a major role in adaptation, and gene families underlying chemosensation are particularly interesting due to their essential role in chemical recognition of mates, predators and food resources. Social insects add yet another dimension to the study of chemosensory genomics, as the key components of their social life rely on chemical communication. Still, chemosensory gene families are little studied in social insects. Here we annotated chemosensory protein (CSP) genes from seven ant...

Data from: Latitudinal clines in alternative life histories in a geometrid moth

Panu Välimäki, Sami M. Kivelä, Maarit I. Mäenpää & Toomas Tammaru
The relative roles of genetic differentiation and developmental plasticity in generating latitudinal gradients in life histories remain insufficiently understood. In particular, this applies to determination of voltinism (annual number of generations) in short-lived ectotherms, and the associated trait values. We studied different components of variation in development of Chiasmia clathrata (Lepidoptera: Geometridae) larvae that originated from populations expressing univoltine, partially bivoltine or bivoltine phenology along a latitudinal gradient of season length. Indicative of population-level genetic...

Data from: Genetic basis of local adaptation and flowering time variation in Arabidopsis lyrata

Päivi H. Leinonen, David L. Remington, Johanna Leppälä & Outi Savolainen
Understanding how genetic variation at individual loci contributes to adaptation of populations to different local environments is an important topic in modern evolutionary biology. To date, most evidence has pointed to conditionally neutral quantitative trait loci (QTL) showing fitness effects only in some environments, while there has been less evidence for single-locus fitness trade-offs. At QTL underlying local adaptation, alleles from the local population are expected to show a fitness advantage. Cytoplasmic genomes also can...
