Data from: Maternal predator-exposure has life-long consequences for offspring learning in threespined sticklebacks

Daniel P. Roche, Katie E. McGhee & Alison M. Bell
Learning is an important form of phenotypic plasticity that allows organisms to adjust their behaviour to the environment. An individual’s learning performance can be affected by its mother’s environment. For example, mothers exposed to stressors such as restraint and forced swimming often produce offspring with impaired learning performance. However, it is unclear whether there are maternal effects on offspring learning when mothers are exposed to ecologically relevant stressors such as predation risk. Here, we examined...

Data from: A gain-of-function polymorphism controlling complex traits and fitness in nature

Kasavajhala V. S. K. Prasad, Bao-Hua Song, Carrie Olson-Manning, Jill T. Anderson, Cheng-Ruei Lee, M. Eric Schranz, Aaron J. Windsor, Maria J. Clauss, Antonio J. Manzaneda, Ibtehaj Naqvi, Michael Reichelt, Jonathan Gershenzon, Sanjeewa G. Rupasinghe, Mary A. Schuler & Thomas Mitchell-Olds
Identification of the causal genes that control complex trait variation remains challenging, limiting our appreciation of the evolutionary processes that influence polymorphisms in nature. We cloned a quantitative trait locus that controls plant defensive chemistry, damage by insect herbivores, survival, and reproduction in the natural environments where this polymorphism evolved. These ecological effects are driven by duplications in the BCMA (branched-chain methionine allocation) loci controlling this variation and by two selectively favored amino acid changes...

Data from: A test for environmental effects on behavioral isolation in two species of killifish

Emma L. Berdan & Rebecca C. Fuller
Behavioral isolation is a common and potent mechanism of reproductive isolation. Determining the extent to which behavioral isolation varies with environmental conditions is critical to understanding speciation and the maintenance of species boundaries. Here, we tested the effect of salinity on behavioral isolation (female species recognition, male-male competition, male species recognition) between two closely related killifish (Lucania goodei and L. parva) that differ in salinity tolerance. We performed no-choice assays and behavioral trials where males...

Data from: Genomic basis of life history evolution in Drosophila melanogaster

Silvia C. Remolina, Peter L. Chang, Jeff Leips, Sergey V. Nuzhdin & Kimberly A. Hughes
Natural diversity in aging and other life history patterns is a hallmark of organismal variation. Related species, populations, and individuals within populations show genetically based variation in life span and other aspects of age-related performance. Population differences are especially informative because these differences can be large relative to within-population variation and because they occur in organisms with otherwise similar genomes. We used experimental evolution to produce populations divergent for life span and late-age fertility and...

Data from: The evolution of locomotor rhythmicity in tetrapods

Callum F. Ross, Richard W. Blob, David R. Carrier, Monica A. Daley, Stephen M. Deban, Brigitte Demes, Janaya L. Gripper, Jose Iriarte-Diaz, Brandon Michael Kilbourne, Tobias Landberg, John D. Polk, Nadja Schilling & Bieke Vanhooydonck
Differences in rhythmicity (relative variance in cycle period) between mammal, fish, and lizard feeding systems have been hypothesized to be associated with differences in their sensorimotor control systems. We tested this hypothesis by examining whether the locomotion of tachymetabolic tetrapods (birds and mammals) is more rhythmic than that of bradymetabolic tetrapods (lizards, alligators, turtles, salamanders). Species averages of intra-individual coefficients of variation in cycle period were compared while controlling for gait and substrate. Variance in...

Data from: The effects of age, sex, and habitat on body size and shape of the blackstripe topminnow, Fundulus notatus

Daniel P. Welsh, Muchu Zhou, Steven M. Mussmann, Lauren G. Fields, Claire L. Thomas, Simon P. Pearish, Stephanie L. Kilburn, Jerrod L. Parker, Laura R. Stein, Jennifer A. Bartlett, Christopher R. Bertram, Thomas J. Bland, Kate L. Laskowski, Brett C. Mommer, Xuan Zhuang & Rebecca C. Fuller
Lake and stream habitats pose a variety of challenges to fishes due to differences in variables such as water velocity, habitat structure, prey community, and predator community. These differences can cause divergent selection on body size and/or shape. Here, we measured sex, age, length, and eight different morphological traits of the blackstripe topminnow, Fundulus notatus, from 19 lake and stream populations across four river drainages in central Illinois. Our goal was to determine whether size...

Data from: Decoupling of genetic and phenotypic divergence in a headwater landscape

Winsor H. Lowe, Mark A. McPeek, Gene E. Likens & Bradley J. Cosentino
In stream organisms, the landscape affecting intraspecific genetic and phenotypic divergence is comprised of two fundamental components: the stream network and terrestrial matrix. These components are known to differentially influence genetic structure in stream species, but, to our knowledge, no study has compared their effects on genetic and phenotypic divergence. We examined how the stream network and terrestrial matrix affect genetic and phenotypic divergence in two stream salamanders, Gyrinophilus porphyriticus and Eurycea bislineata, in the...

Data from: Multi-scale model of CRISPR-induced coevolutionary dynamics: diversification at the interface of Lamarck and Darwin

Lauren Maressa Childs, Nicole L. Held, Mark J. Young, Rachel J. Whitaker & Joshua S. Weitz
The CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) system is a recently discovered type of adaptive immune defense in bacteria and archaea that functions via directed incorporation of viral and plasmid DNA into host genomes. Here, we introduce a multi-scale model of dynamic coevolution between hosts and viruses in an ecological context that incorporates CRISPR immunity principles. We analyze the model to test whether and how CRISPR immunity induces host and viral diversification and the...

Data from: A phylogenetic analysis of the megadiverse Chalcidoidea (Hymenoptera)

Woolley, Lars Krogmann, Steve Heydon, Andrew Polaszek, Stefan Schmidt, D. Chris Darling, Michael W. Gates, Jason Mottern, Elizabeth Murray, Ana Dal Molin, Serguei Triapitsyn, Hannes Baur, John D. Pinto, Simon Van Noort … & Matthew Yoder
Chalcidoidea (Hymenoptera) is extremely diverse with an estimated 500 000 species. We present the first phylogenetic analysis of the superfamily based on both morphological and molecular data. A web-based, systematics workbench mx was used to score 945 character states illustrated by 648 figures for 233 morphological characters for a total of 66 645 observations for 300 taxa. The matrix covers 22 chalcidoid families recognized herein and includes 268 genera within 78 of 83 subfamilies. Morphological...
