Data from: Resolving the evolutionary relationships of molluscs with phylogenomic tools

Stephen A. Smith, Casey W. Dunn, Nerida G. Wilson, Freya E. Goetz, Caitlin Feehery, Sónia C. S. Andrade, Greg W. Rouse & Gonzalo Giribet
Molluscs (snails, octopuses, clams, and relatives) have great body plan disparity, and among animals only arthropods surpass them in species number. This diversity has made Mollusca one of the best-studied groups of animals, yet their evolutionary relationships remain poorly resolved. Open questions have important implications for the origin of Mollusca and morphological evolution within the group. These include whether the shell-less vermiform aplacophoran molluscs diverged prior to the origin of the shelled molluscs (Conchifera), or...

Data from: DOG1 expression is predicted by the seed-maturation environment and contributes to geographic variation in germination in Arabidopsis thaliana.

George C K Chiang, Melanie Bartsch, Deepak Barua, Kazumi Nakabayashi, Marilyne Debieu, Ilkka Kronholm, Maarten Koornneef, Wim J J Soppe, Kathleen Donohue & Juliette De Meaux
Seasonal germination timing of Arabidopsis thaliana strongly influences overall life history expression and is the target of intense natural selection. This seasonal germination timing depends strongly on the interaction between genetics and seasonal environments both before and after seed dispersal. DELAY OF GERMINATION 1 (DOG1) is the first gene that has been identified to be associated with natural variation in primary dormancy in Arabidopsis thaliana. Here, we report inter-accession variation in DOG1 expression and document...

Data from: Step matrices and the interpretation of homoplasy

Richard H. Ree & Michael J. Donoghue
Assumptions about the costs of character change, coded in the form of a step matrix, determine most-parsimonious inferences of character evolution on phylogenies. We present a graphical approach to exploring the relationship between cost assumptions and evolutionary inferences from character data. The number of gains and losses of a binary trait on a phylogeny can be plotted over a range of cost assumptions, to reveal the inflection point at which there is a switch from...

Data from: Persistence of an extreme male-biased adult sex ratio in a natural population of polyandrous bird

András Kosztolányi, Zoltan Barta, Clemens Küpper & Tamás Székely
In a number of insects, fishes and birds the conventional sex roles are reversed: males are the main care provider whereas females focus on matings. The reversal of typical sex roles is an evolutionary puzzle, because it challenges the foundations of sex roles, sexual selection and parental investment theory. Recent theoretical models predict that biased parental care may be a response to biased adult sex ratios (ASRs). However, estimating ASR is challenging in natural populations,...

Data from: Strict monandry in the ponerine army ant genus Simopelta suggests that colony size and complexity drive mating system evolution in social insects

Daniel J. C. Kronauer, Sean O'Donnell, Jacobus J. Boomsma & Naomi E. Pierce
Altruism in social insects has evolved between closely related full-siblings. It is therefore of considerable interest why some groups have secondarily evolved low within-colony relatedness, which in turn affects the relatedness incentives of within-colony cooperation and conflict. The highest queen mating frequencies, and therefore among the lowest degrees of colony relatedness, occur in Apis honeybees and army ants of the subfamilies Aenictinae, Ecitoninae, and Dorylinae, suggesting that common life-history features such as reproduction by colony...

Data from: Major histocompatability complex variation in insular populations of the Egyptian vulture: inferences about the roles of genetic drift and selection

Rosa Agudo, Miguel Alcaide, Ciro Rico, Jesus Angel Lemus, Guillermo Blanco, Fernando Hiraldo & Jose Antonio Donázar
Insular populations have attracted the attention of evolutionary biologists because of their morphological and ecological peculiarities with respect to their mainland counterparts. Founder effects and genetic drift are known to distribute neutral genetic variability in these demes. However, elucidating whether these evolutionary forces have also shaped adaptive variation is crucial to evaluate the real impact of reduced genetic variation in small populations. Genes of the Major Histocompatibility Complex (MHC) are classical examples of evolutionarily relevant...

Data from: Adaptation and plasticity of animal communication in fluctuating environments

Terry J. Ord, Judy A. Stamps & Jonathan B. Losos
Adaptations that facilitate the reception of long-range signals under challenging conditions are expected to generate signal diversity when species communicate in different habitats. While we have a general understanding of how individual communicating animals cope with conditions influencing signal detection, the extent to which plasticity and evolutionary changes in signal characteristics contribute to interspecific differences in signaling behavior is unclear. We quantified the visual displays of free-living lizards and environmental variables known to influence display...

Data from: Incongruence between morphological and mitochondrial-DNA characters suggests hybrid origins of parthenogenetic weevil lineages (genus Aramigus)

Benjamin Normark & Analia A. Lanteri
An expanded matrix of morphological characters for the genus Aramigus (Coleoptera: Curculionidae), which includes numerous polyploid parthenogenetic lineages, was compared and combined with a published matrix of mitochondrial DNA (mtDNA) characters. The matrix of morphological characters provides little resolution of the A. tessellatus and A. uruguayensis species complexes but does resolve previously unresolved relationships among other morphologically defined species (A. globoculus + A. intermedius, A. curtulus + A. planioculus). The morphological and mtDNA characters are...

Data from: Molecular phylogeny and biogeography of Malagasy frogs of the genus Gephyromantis

Nathalie Kaffenberger, Katharina C. Wollenberg, Jörn Köhler, Frank Glaw, David R. Vieites & Miguel Vences
The genus Gephyromantis is a clade within the Malagasy–Comoroan family Mantellidae composed of rainforest frogs that live and breed to varying degrees independently from water. Based on DNA sequences of five mitochondrial and five nuclear genes we inferred the phylogeny of these frogs with full taxon coverage at the species level. Our preferred consensus tree from a partitioned Bayesian analysis of 5843 base pairs of 51 nominal and candidate species supports various major clades within...
