Data from: The role of pleiotropy and linkage in genes affecting a sexual ornament and bone allocation in the chicken

Sexual selection and the ornaments that inform such choices have been extensively studied, particularly from a phenotypic perspective. Although more is being revealed about the genetic architecture of sexual ornaments, much still remains to be discovered. The comb of the chicken is one of the most widely recognized sexual ornaments, which has been shown to be correlated with both fecundity and bone allocation. In this study we use a combination of multiple intercrosses between White...

Data from: The influence of mitonuclear genetic variation on personality in seed beetles

Hanne Løvlie, Elina Immonen, Emil Gustavsson, Erem Kazancioğlu, Göran Arnqvist & H. Lovlie
There is a growing awareness of the influence of mitochondrial genetic variation on life-history phenotypes, particularly via epistatic interactions with nuclear genes. Owing to their direct effect on traits such as metabolic and growth rates, mitonuclear interactions may also affect variation in behavioural types or personalities (i.e. behavioural variation that is consistent within individuals, but differs among individuals). However, this possibility is largely unexplored. We used mitonuclear introgression lines, where three mitochondrial genomes were introgressed...

Data from: Personality predicts social dominance in male domestic fowl

Anna Favati, Olof Leimar & Hanne Løvlie
Individuals in social species commonly form dominance relationships, where dominant individuals enjoy greater access to resources compared to subordinates. A range of factors such as sex, age, body size and prior experiences has to varying degrees been observed to affect the social status an individual obtains. Recent work on animal personality (i.e. consistent variation in behavioural responses of individuals) demonstrates that personality can co-vary with social status, suggesting that also behavioural variation can play an...

Data from: Coarse dark patterning functionally constrains adaptive shifts from aposematism to crypsis in strawberry poison frogs

Anna Qvarnström, Andreas Rudh, Torkel Edström, Anders Ödeen, Hanne Løvlie, Birgitta Tullberg & Birgitta S. Tullberg
Ecological specialization often requires tight co-evolution of several traits, which may constrain future evolutionary pathways and make species more prone to extinction. Aposematism and crypsis represent two specialized adaptations to avoid predation. We tested whether the combined effects of color and pattern on prey conspicuousness functionally constrain or facilitate shifts between these two adaptations. We combined data from 17 natural populations of Strawberry poison frogs, Oophaga pumilio with an experimental approach using digitalized images of...

Data from: Farmers without borders - genetic structuring in century old barley (Hordeum vulgare)

Jenny Hagenblad, Nils E. G. Forsberg, Joanne Russell, Malcolm Macaulay & Matti W. Leino
The geographic distribution of genetic diversity can reveal the evolutionary history of a species. For crop plants, phylogeographic patterns also indicate how seed has been exchanged and spread in agrarian communities. Such patterns are, however, easily blurred by the intense seed trade, plant improvement and even genebank conservation during the twentieth century, and discerning fine-scale phylogeographic patterns is thus particularly challenging. Using historical crop specimens, these problems are circumvented and we show here how high-throughput...

Data from: Comparative support for the expensive tissue hypothesis: big brains are correlated with smaller gut and greater parental investment in Lake Tanganyika cichlids

The brain is one of the most energetically expensive organs in the vertebrate body. Consequently, the energetic requirements of encephalization are suggested to impose considerable constraints on brain size evolution. Three main hypotheses concerning how energetic constraints might affect brain evolution predict covariation between brain investment and i) investment into other costly tissues, ii) overall metabolic rate, and iii) reproductive investment. To date, these hypotheses have mainly been tested in homeothermic animals and the existing...
