Data from: Variance in reproductive success is driven by environmental factors not mating system in Bonytail

Megan J. Osborne, Alyssa V. Sanchez, Thomas E. Dowling & Thomas F. Turner
Studying the reproductive ecology of aggregate broadcast spawning fishes is difficult because it generally is not feasible to sample all potential parents and unambiguously assign their offspring. We used molecular‐based parentage analysis to gain insights into the reproductive ecology of the endangered Bonytail, and to evaluate whether protected off‐channel habitats could be used as an alternative to hatchery production. By genotyping adults and offspring stocked (n = 4130) into two experimental backwaters across three years,...

Data from: Evolution of longevity improves immunity in Drosophila

Much has been learned about the genetics of aging from studies in model organisms, but still little is known about naturally occurring alleles that contribute to variation in longevity. For example, analysis of mutants and transgenes has identified insulin signaling as a major regulator of longevity, yet whether standing variation in this pathway underlies microevolutionary changes in lifespan and correlated fitness traits remains largely unclear. Here we have analyzed the genomes of a set of...

Data from: A robust and tunable mitotic oscillator in artificial cells

Ye Guan, Zhengda Li, Shiyuan Wang, Patrick M Barnes, Xuwen Liu, Haotian Xu, Minjun Jin, Allen P Liu & Qiong Yang
Single-cell analysis is pivotal to deciphering complex phenomena like heterogeneity, bistability, and asynchronous oscillations, where a population ensemble cannot represent individual behaviors. Bulk cell-free systems, despite having unique advantages of manipulation and characterization of biochemical networks, lack the essential single-cell information to understand a class of out-of-steady-state dynamics including cell cycles. Here, by encapsulating Xenopus egg extracts in water-in-oil microemulsions, we developed artificial cells that are adjustable in sizes and periods, sustain mitotic oscillations for...

Data from: Are there general laws for digit evolution in squamates? The loss and re-evolution of digits in a clade of fossorial lizards (Brachymeles, Scincinae)

Günter P. Wagner, Oliver W. Griffith, Philip J. Bergmann, Gaelle Bello-Hellegouarch, Tiana Kohlsdorf, Anjan Bhullar & Cameron D. Siler
Evolutionary simplification of autopodial structures is a major theme in studies of body‐form evolution. Previous studies on amniotes have supported Morse's law, that is, that the first digit reduced is Digit I, followed by Digit V. Furthermore, the question of reversibility for evolutionary digit loss and its implications for “Dollo's law” remains controversial. Here, we provide an analysis of limb and digit evolution for the skink genus Brachymeles. Employing phylogenetic, morphological, osteological, and myological data,...

Data from: Standing geographic variation in eclosion time and the genomics of host race formation in Rhagoletis pomonella fruit flies

Meredith M. Doellman, Scott P. Egan, Gregory J. Ragland, Peter J. Meyers, Glen R. Hood, Thomas H.Q. Powell, Peter Lazorchak, Daniel A. Hahn, Stewart H. Berlocher, Patrik Nosil, Jeff L. Feder, Jeffrey L. Feder & Thomas H. Q. Powell
Taxa harboring high levels of standing variation may be more likely to adapt to rapid environmental shifts and experience ecological speciation. Here, we characterize geographic and host-related differentiation for 10,241 single nucleotide polymorphisms in Rhagoletis pomonella fruit flies to infer if standing genetic variation in adult eclosion time in the ancestral hawthorn (Crataegus spp.)-infesting host race, as opposed to new mutations, contributed substantially to its recent shift to earlier fruiting apple (Malus domestica). Allele frequency...
