Data from: The evolution of XY-recombination: sexually antagonistic selection versus deleterious mutation load

Christine Grossen, Samuel Neuenschwander & Nicolas Perrin
Recombination arrest between X and Y chromosomes, driven by sexually antagonistic genes, is expected to induce their progressive differentiation. However, in contrast to birds and mammals (which display the predicted pattern), most cold-blooded vertebrates have homomorphic sex chromosomes. Two main hypotheses have been proposed to account for this, namely high turnover rates of sex determining systems and occasional XY recombination. Using individual-based simulations, we formalize the evolution of XY recombination (here mediated by sex reversal;...

Data from: More than 1000 ultraconserved elements provide evidence that turtles are the sister group of archosaurs

Nicholas G. Crawford, Brant C. Faircloth, John E. McCormack, Robb T. Brumfield, Kevin Winker & Travis C. Glenn
We present the first genomic-scale analysis addressing the phylogenetic position of turtles, using over 1,000 loci from representatives of all major reptile lineages including tuatara. Previously, studies of morphological traits positioned turtles either at the base of the reptile tree or with lizards, snakes, and tuatara (lepidosaurs), whereas molecular analyses typically allied turtles with crocodiles and birds (archosaurs). A recent analysis of shared microRNA families found that turtles are more closely related to lepidosaurs. To...

Data describing variation in male lifetime reproductive success and fitness

Data from: Correlated evolution of mating system and floral display traits in flowering plants and its implications for the distribution of mating system variation

Carol Goodwillie, Risa D. Sargent, Susan Kalisz, Richard H. Ree, David A. Moeller, Mario Vallejo-Marin, Christopher G. Eckert, Alice A. Winn, Elizabeth Elle, Monica A. Geber & Mark O. Johnston
Reduced allocation to structures for pollinator attraction is predicted in selfing species. We explored the association between outcrossing and floral display in a broad sample of angiosperms. We used the demonstrated relationship to test for bias against selfing species in the outcrossing rate distribution, the shape of which has relevance for the stability of mixed mating. Relationships between outcrossing rate, flower size, flower number and floral display, measured as the product of flower size and...

Data from: Simultaneous delimitation of species and quantification of interspecific hybridization in Amazonian peacock cichlids (genus Cichla) using multi-locus data

Stuart C. Willis, Jason Macrander, Izeni P. Farias & Guillermo Orti
BACKGROUND: Introgression likely plays a significant role in evolution, but understanding the extent and consequences of this process requires a clear identification of species boundaries in each focal group. The delimitation of species, however, is a contentious endeavor. This is true not only because of the inadequacy of current tools to identify species lineages, but also because of the inherent ambiguity between natural populations and species paradigms. The result has been a debate about the...

Data from: Nondestructive sampling of insect DNA from defensive secretion

Hannah M. Donald, Corlett W. Wood, Kyle M. Benowitz, Rebecca A. Johnson, & Vincent A. Formica
Nondestructive techniques to obtain DNA from organisms can further genetic analyses such as estimating genetic diversity, dispersal, and lifetime fitness, without permanently removing individuals from the population. Possible DNA sources for insects include wing and leg clippings or frass samples. However, these are not feasible approaches for organisms that cannot be removed from their natural environment for long periods or when adverse effects of tissue removal must be avoided. This study evaluated the impacts and...

Data from: Dissecting the genetic architecture of F1 hybrid sterility in house mice

Maria Dzur-Gejdošová, Petr Simecek, Sona Gregorova, Tanomy Bhattacharyya & Jiri Forejt
Hybrid sterility as a postzygotic reproductive isolation mechanism has been studied for over 80 years, yet the first identifications of hybrid sterility genes in Drosophila and mouse are quite recent. To study the genetic architecture of F_1 hybrid sterility between young subspecies of house mouse Mus m. domesticus and Mus m. musculus we conducted QTL analysis of a backcross between inbred strains representing these two subspecies and probed the role of individual chromosomes in hybrid...

Data from: Reconstructing the origin and spread of horse domestication in the Eurasian steppe

Vera Warmuth, Anders Eriksson, Mim Ann Bower, Graeme Barker, Elizabeth Barrett, Bryan Kent Hanks, Shuicheng Li, David Lomitashvili, Maria Ochir-Goryaeva, Grigory Victor Sizonov & Vasiliy Soyonov
History of horse domestication remains poorly understood. On the basis of current evidence from archaeology, mitochondrial DNA, and Y-chromosomal sequencing, a number of different domestication scenarios have been proposed, ranging from the spread of domestic horses out of a restricted primary area of domestication to the domestication of numerous distinct wild horse populations. In this paper, we reconstruct both the population genetic structure of the extinct wild progenitor of domestic horses, Equus ferus, and the...

Data from: The evolution of alternative developmental pathways: footprints of selection on life-history traits in a butterfly

Inger M. Aalberg Haugen, David Berger & Karl Gotthard
Developmental pathways may evolve to optimize alternative phenotypes across environments. However, the maintenance of such adaptive plasticity under relaxed selection has received little study. We compare expression of life history traits across two developmental pathways in two populations of the butterfly Pararge aegeria where both populations express a diapause pathway but one never expresses direct development in nature. In the population with ongoing selection on both pathways the difference between pathways in development time and...

Data from: Slowly switching between environments facilitates reverse evolution in small populations

Longzhi Tan & Jeff Gore
Natural populations must constantly adapt to ever-changing environmental conditions. A particularly interesting question is whether such adaptations can be reversed by returning the population to an ancestral environment. Such evolutionary reversals have been observed in both natural and laboratory populations. However, the factors that determine the reversibility of evolution are still under debate. The timescales of environmental change vary over a wide range, but little is known about how the rate of environmental change influences...

Data from: Selection in a fluctuating environment and the evolution of sexual dimorphism in the seed beetle Callosobruchus maculatus

Lára R. Hallsson & Mats Björklund
Temperature changes in the environment, which realistically include environmental fluctuations, can create both plastic and evolutionary responses of traits. Sexes might differ in either or both of these responses for homologous traits, which in turn has consequences for sexual dimorphism and its evolution. Here we investigate both immediate changes in and the evolution of sexual dimorphism in response to a changing environment (with and without fluctuations) using the seed beetle Callosobruchus maculatus. We investigate sex...

Data from: Ontogeny tends to recapitulate phylogeny in digital organisms

Jeff Clune, Robert T. Pennock, Charles Ofria & Richard E. Lenski
Biologists have long debated whether ontogeny recapitulates phylogeny and, if so, why. Two plausible explanations are that (i) changes to early developmental stages are selected against because they tend to disrupt later development and (ii) simpler structures often precede more complex ones in both ontogeny and phylogeny if the former serve as building blocks for the latter. It is difficult to test these hypotheses experimentally in natural systems, so we used a computational system that...

Data from: Experimental evolution of Legionella pneumophila in mouse macrophages leads to strains with altered determinants of environmental survival

Alexander W. Ensminger, Yosuf Yassin, Alexander Miron & Ralph R. Isberg
The Gram-negative bacterium, Legionella pneumophila, is a protozoan parasite and accidental intracellular pathogen of humans. We propose a model in which host cycling through multiple protozoan hosts in the environment holds L. pneumophila in a state of evolutionary stasis as a broad host-range pathogen. Using an experimental evolution approach, we tested this hypothesis by restricting L. pneumophila to growth within mouse macrophages for hundreds of generations. Whole-genome resequencing and high-throughput genotyping identified several parallel adaptive...

Data from: Crossing the divide: gene flow produces intergeneric hybrid in feral transgenic creeping bentgrass population

María L. Zapiola & Carol A. Mallory-Smith
Gene flow is the most frequently expressed public concern related to the deregulation of transgenic events (Snow 2002; Ellstrand 2003). However, assessing the potential for transgene escape is complex because it depends on the opportunities for unintended gene flow, and establishment and persistence of the transgene in the environment (Warwick et al. 2008). Creeping bentgrass (Agrostis stolonifera L.), a turfgrass species widely used on golf courses, has been genetically engineered to be resistant to glyphosate,...
