Data from: Temporal identity establishes columnar neuron morphology, connectivity, and function in a Drosophila navigation circuit

Luis F. Sullivan, Timothy L. Warren & Chris Q. Doe
The insect central complex (CX) is a conserved brain region containing 60+ neuronal subtypes, several of which contribute to navigation. It is not known how CX neuronal diversity is generated or how developmental origin of subtypes relates to function. We mapped the developmental origin of four key CX subtypes and found that neurons with similar origin have similar axon/dendrite targeting. Moreover, we found that the temporal transcription factor (TTF) Eyeless/Pax6 regulates the development of two...

Data from: Variation in ecophysiological traits might contribute to ecogeographic isolation and divergence between parapatric ecotypes of Mimulus aurantiacus

James M. Sobel, Sean Stankowski & Matthew A. Streisfeld
Many forms of reproductive isolation contribute to speciation, and early acting barriers may be especially important, because they have the first opportunity to limit gene flow. Ecogeographic isolation occurs when intrinsic traits of taxa contribute to disjunct geographic distributions, reducing the frequency of inter‐taxon mating. Characterizing this form of isolation requires knowledge of both the geographic arrangement of suitable habitats in nature and the identification of phenotypes involved in shaping geographic distributions. In Mimulus aurantiacus,...

Data from: Prairie plant phenology driven more by temperature than moisture in climate manipulations across a latitudinal gradient in the Pacific Northwest, USA

Paul B. Reed, Laurel E. Pfeifer-Meister, Bitty A. Roy, Bart R. Johnson, Graham T. Bailes, Aaron A. Nelson, Peg C. Boulay, Sarah T. Hamman & Scott D. Bridgham
Plant phenology will likely shift with climate change, but how temperature and/or moisture regimes will control phenological responses is not well understood. This is particularly true in Mediterranean climate ecosystems where the warmest temperatures and greatest moisture availability are seasonally asynchronous. We examined plant phenological responses at both the population and community levels to four climate treatments (control, warming, drought, and warming plus additional precipitation) embedded within three prairies across a 520 km latitudinal Mediterranean...

Data from: Minor allele frequency thresholds strongly affect population structure inference with genomic datasets

Ethan Linck & C.J. Battey
One common method of minimizing errors in large DNA sequence datasets is to drop variable sites with a minor allele frequency below some specified threshold. Though widespread, this procedure has the potential to alter downstream population genetic inferences and has received relatively little rigorous analysis. Here we use simulations and an empirical SNP dataset to demonstrate the impacts of minor allele frequency (MAF) thresholds on inference of population structure. We find that model-based inference of...

Data from: Evidence of linked selection on the Z chromosome of hybridizing hummingbirds

C. J. Battey
Levels of genetic differentiation vary widely along the genomes of recently diverged species. What processes cause this variation? Here I analyze geographic population structure and genome-wide patterns of variation in the Rufous, Allen's, and Calliope Hummingbirds (Selasphorus rufus/sasin/calliope) and assess evidence that linked selection on the Z chromosome drives patterns of genetic differentiation in a pair of hybridizing species. Demographic models, introgression tests, and genotype clustering analyses support a reticulate evolutionary history consistent with divergence...

Data from: Increases and decreases in marine disease reports in an era of global change

Allison M. Tracy, Madeline L. Pielmeier, Reyn M. Yoshioka, Scott F. Heron & C. Drew Harvell
Outbreaks of marine infectious diseases have caused widespread mass mortalities, but the lack of baseline data has precluded evaluating whether disease is increasing or decreasing in the ocean. We use an established literature proxy method from Ward and Lafferty (2004) to analyze a 44-year global record of normalized disease reports from 1970 to 2013. Major marine hosts are combined into nine taxonomic groups, from seagrasses to marine mammals, to assess disease swings, defined as positive...

Data from: Black abalone (Haliotis cracherodii) population structure shifts through deep time: Management implications for southern California's northern Channel Islands

Hannah Haas, Todd J. Braje, Matthew S. Edwards, Jon M. Erlandson & Steven G. Whitaker
For over 10,000 years, black abalone (Haliotis cracherodii) were an important resource in southern California, first for coastal Native Americans, then beginning in the nineteenth century, as one of the state's first commercial shellfisheries. By 1993, after years of heavy fishing, rising sea surface temperatures (SST), and the spread of withering syndrome (WS), black abalone populations declined dramatically, resulting in the closure of the Alta California fishery. After nearly 25 years of management and recovery...

Data from: A phylum-wide survey reveals multiple independent gains of head regeneration in Nemertea

Eduardo Zattara, Fernando Fernández-Álvarez, Terra Hiebert, Alexa Bely & Jon Norenburg
Animals vary widely in their ability to regenerate, suggesting that regenerative ability has a rich evolutionary history. However, our understanding of this history remains limited because regenerative ability has only been evaluated in a tiny fraction of species. Available comparative regeneration studies have identified losses of regenerative ability, yet clear documentation of gains is lacking. We assessed ability to regenerate heads and tails either through our own experiments or from literature reports for 35 species...

High-speed video recordings of Müller's larva swimming and feeding

George Von Dassow
These data form the basis for the paper "Large-scale ciliary reversal mediates capture of individual algal prey by Müller's larva" by George von Dassow and Christina I. Ellison, in press at Invertebrate Biology as of late 2019 (preprint on bioRxiv, doi.org/10.1101/709790). Wild-caught Müller's larva of several species of polyclad flatworm were observed swimming and feeding on unicellular algae using high-speed video. These videos document local ciliary reversal mediating prey capture, one cell at a time,...
