Data from: Climate-mediated movement of an avian hybrid zone

Scott A. Taylor, Thomas A. White, Wesley M. Hochachka, Valentina Ferretti, Robert L. Curry & Irby Lovette
The interaction between sibling species that share a zone of contact is a multifaceted relationship affected by climate change. Between sibling species, interactions may occur at whole-organism (direct or indirect competition) or genomic (hybridization and introgression) levels. Tracking hybrid zone movements can provide insights about influences of environmental change on species interactions. Here, we explore the extent and mechanism of movement of the contact zone between black-capped chickadees (Poecile atricapillus) and Carolina chickadees (Poecile carolinensis)...

Data from: Demographic history of a recent invasion of house mice on the isolated Island of Gough

Melissa M. Gray, Daniel Wegmann, Ryan J. Haasl, Michael A. White, Sofia I. Gabriel, Jeremy B. Searle, Richard J. Cuthbert, Peter G. Ryan & Bret A. Payseur
Island populations provide natural laboratories for studying key contributors to evolutionary change, including natural selection, population size, and the colonization of new environments. The demographic histories of island populations can be reconstructed from patterns of genetic diversity. House mice (Mus musculus) inhabit islands throughout the globe, making them an attractive system for studying island colonization from a genetic perspective. Gough Island, in the central South Atlantic Ocean, is one of the remotest islands in the...

Data from: Climate, physiological tolerance, and sex-biased dispersal shape genetic structure of Neotropical orchid bees

Margarita M. Lopez-Uribe, Kelly R. Zamudio, Carolina F. Cardoso & Bryan N. Danforth
Understanding the impact of past climatic events on the demographic history of extant species is critical for predicting species’ responses to future climate change. Paleoclimatic instability is a major mechanism of lineage diversification in taxa with low dispersal and small geographic ranges in tropical ecosystems. However, the impact of these climatic events remains questionable for the diversification of species with high levels of gene flow and large geographic distributions. In this study, we investigate the...

Data from: Barriers, rather than refugia, underlie the origin of diversity in toads endemic to the Brazilian Atlantic Forest

Maria Tereza C. Thomé, Kelly R. Zamudio, Célio F. B. Haddad & João Alexandrino
In this study, we investigated the relative contribution of geographic barriers and Pleistocene refuges in the diversification of the Rhinella crucifer species complex, a group of endemic toads with a widespread distribution in the Brazilian Atlantic Forest (AF). We used intensive sampling and multilocus DNA sequence data to compare nucleotide diversity between refuge and nonrefuge areas, investigate regional demographic patterns, estimate demographic parameters related to genetic breaks and test refuge versus barrier scenarios of diversification...

Data from: Tomato GOLDEN2-LIKE transcription factors reveal molecular gradients that function during fruit development and ripening

Cuong V. Nguyen, Julia T. Vrebalov, Nigel E. Gapper, Yi Zheng, Silin Zhong, Zhangjun Fei & James J. Giovannoni
Fruit ripening is the summation of changes rendering fleshy fruit tissues attractive and palatable to seed dispersing organisms. For example, sugar content is influenced by plastid numbers and photosynthetic activity in unripe fruit and later by starch and sugar catabolism during ripening. Tomato fruit are sinks of photosynthate, yet unripe green fruit contribute significantly to the sugars that ultimately accumulate in the ripe fruit. Plastid numbers and chlorophyll content are influenced by numerous environmental and...

Data from: Transcriptomic characterization of the immunogenetic repertoires of heteromyid rodents

Nicholas J. Marra & J. Andrew DeWoody
Background: When populations evolve under disparate environmental conditions, they experience different selective pressures that shape patterns of sequence evolution and gene expression. These may be manifested in genetic and phenotypic differences such as a diverse immunogenetic repertoire in species from tropical latitudes that have greater and/or different parasite burdens than more temperate species. To test this idea, we compared the transcriptomes of one tropical species (Heteromys desmarestianus) and two species from temperate latitudes (Dipodomys spectabilis...

Data from: Blacktip reef sharks, Carcharhinus melanopterus, have high genetic structure and varying demographic histories in their Indo-Pacific range

Thomas M. Vignaud, Johann Mourier, Jeffrey A. Maynard, Raphael Leblois, Julia L. Y. Spaet, Eric Clua, Valentina Neglia, Serge Planes & Julia L.Y. Spaet
For free-swimming marine species like sharks, only population genetics and demographic history analyses can be used to assess population health/status as baseline population numbers are usually unknown. We investigated the population genetics of blacktip reef sharks, Carcharhinus melanopterus; one of the most abundant reef-associated sharks and the apex predator of many shallow water reefs of the Indian and Pacific Oceans. Our sampling includes 4 widely separated locations in the Indo-Pacific and 11 islands in French...

Data from: Aboveground herbivory by red milkweed beetles facilitates above- and below-ground conspecific insects and reduces fruit production in common milkweed

Alexis C. Erwin, Tobias Züst, Jared G. Ali & Anurag A. Agrawal
1. Initial herbivory and induced plant responses can influence subsequent above- and belowground herbivore attack. When two life stages of the same herbivore damage different plant parts sequentially, there is strong potential for plants to respond with induced plant defense against the later attacker. Alternatively, the earlier attacker could manipulate the host plant to facilitate the later-feeding life stage. 2. We studied herbivory by foliage-feeding adults and root-feeding larvae of the red milkweed beetle (Tetraopes...

Data from: An experimental analysis of the heritability of variation in glucocorticoid concentrations in a wild avian population

Brittany R. Jenkins, Maren N. Vitousek, Joanna K. Hubbard & Rebecca J. Safran
Glucocorticoid hormones (CORT) are predicted to promote adaptation to variable environments, yet little is known about the potential for CORT secretion patterns to respond to selection in free-living populations. We assessed the heritable variation underlying differences in hormonal phenotypes using a cross-foster experimental design with nestling North American barn swallows (Hirundo rustica erythrogaster). Using a bivariate animal model, we partitioned variance in baseline and stress-induced CORT concentrations into their additive genetic and rearing environment components...

Data from: The generification of the fossil record

Jonathan R. Hendricks, Erin E. Saupe, Corinne E. Myers, Elizabeth J. Hermsen & Warren D. Allmon
Many modern paleobiological analyses are conducted at the generic level, a practice predicated on the validity of genera as meaningful proxies for species. Uncritical application of genera in such analyses, however, has led, perhaps inadvertently, to the unjustified reification of genera in an evolutionary context. While the utility of genera as proxies for species in evolutionary studies should be evaluated as an empirical issue, in practice it is increasingly assumed (rather than demonstrated) that genera...

Data from: Genetic diversity among INERA maize inbred lines with single nucleotide polymorphism (SNP) markers and their relationship with CIMMYT, IITA, and temperate lines

Abdalla Dao, Jacob Sanou, Sharon E. Mitchell, Gracen Vernon & Eric Y. Danquah
Background: Genetic diversity provides the capacity for plants to meet changing environments. It is fundamentally important in crop improvement. Fifty-nine local maize lines developed at INERA and 41 exotic (temperate and tropical) inbred lines were characterized using 1057 SNP markers to (1) analyse the genetic diversity in a diverse set of maize inbred lines; (2) determine the level of genetic diversity in INERA inbred lines and patterns of relationships of these inbred lines developed from...

Data from: New insights into New World biogeography: an integrated view from the phylogeny of blackbirds, cardinals, sparrows, tanagers, warblers, and allies

F. Keith Barker, Kevin J. Burns, John Klicka, Scott M. Lanyon & Irby J. Lovette
Understanding the biogeographic origins and temporal sequencing of groups within a region or of lineages within an ecosystem can yield important insights into evolutionary dynamics and ecological processes. Fifty years ago, Ernst Mayr generated comprehensive—if limited—inferences about the origins of the New World avifaunas, including the importance of pre-Isthmian dispersal between North and South America. Since then, methodological advances have improved our ability to address many of the same questions, but the phylogenies upon which...

Data from: A phylogenetic backbone for Bivalvia: an RNA-seq approach

Vanessa L. González, Sónia C. S. Andrade, Rüdiger Bieler, Timothy M. Collins, Casey W. Dunn, Paula M. Mikkelsen, John D. Taylor, Gonzalo Giribet & V. L. Gonzalez
Bivalves are an ancient and ubiquitous group of aquatic invertebrates with an estimated 10 000–20 000 living species. They are economically significant as a human food source, and ecologically important given their biomass and effects on communities. Their phylogenetic relationships have been studied for decades, and their unparalleled fossil record extends from the Cambrian to the Recent. Nevertheless, a robustly supported phylogeny of the deepest nodes, needed to fully exploit the bivalves as a model...

Data from: Constructing predictive models of human running

Horst-Moritz Maus, Shai Revzen, John Guckenheimer, Christian Ludwig, Johann Reger & Andre Seyfarth
Running is an essential mode of human locomotion, during which ballistic aerial phases alternate with phases when a single foot contacts the ground. The spring-loaded inverted pendulum (SLIP) provides a starting point for modelling running, and generates ground reaction forces that resemble those of the centre of mass (CoM) of a human runner. Here, we show that while SLIP reproduces within-step kinematics of the CoM in three dimensions, it fails to reproduce stability and predict...

Data from: Complete dosage compensation and sex-biased gene expression in the moth Manduca sexta

Gilbert Smith, Yun-Ru Chen, Gary W. Bissard & Adriana D. Briscoe
Sex chromosome dosage compensation balances homogametic sex chromosome expression with autosomal expression in the heterogametic sex, leading to sex chromosome expression parity between the sexes. If compensation is incomplete this can lead to expression imbalance and sex-biased gene expression. Recent work has uncovered an intriguing and variable pattern of dosage compensation across species that includes a lack of complete dosage compensation in ZW species compared to XY species. This has led to the hypothesis that...

Data from: Meta-analysis of Arabidopsis thaliana phospho-proteomics data reveals compartmentalization of phosphorylation motifs

Klaas J. Van Wijk, Giulia Friso, Dirk Walther & Waltraud X. Schulze
Protein (de)phosphorylation plays an important role in plants. To provide a robust foundation for subcellular phosphorylation signaling network analysis and kinase-substrate relationships, we performed a meta-analysis of 27 published and unpublished in-house mass spectrometry–based phospho-proteome data sets for Arabidopsis thaliana covering a range of processes, (non)photosynthetic tissue types, and cell cultures. This resulted in an assembly of 60,366 phospho-peptides matching to 8141 nonredundant proteins. Filtering the data for quality and consistency generated a set of...
