Data from: The SETDB2 locus: evidence for a genetic link between handedness and atopic disease

Bernard Crespi, Silven Read & Peter Hurd
The gene SETDB2, which mediates aspects of laterality in animal model systems, has recently been linked with human handedness as measured continuously on a scale from strong left to strong right. By contrast, it was marginally associated with a left-right dichotomous measure, and it showed no evidence of association with absolute handedness strength independent of direction. We genotyped the SETDB2 handedness-associated single nucleotide polymorphism, rs4942830, in a large healthy population likewise phenotyped for continuous, absolute,...

Data from: Ecological legacies of anthropogenic burning in a British Columbia coastal temperate rain forest

Kira M. Hoffman, Ken P. Lertzman & Brian M. Starzomski
Aim Few long-term fire histories have been reconstructed in coastal temperate rain forests, and little is known regarding the spatial and temporal characteristics of lightning and human ignitions. We use a multidisciplinary approach to assess the impact, scale and ecological legacies of historic fires. Location We focus on perhumid temperate rain forests located on the central coast of British Columbia, Canada. Methods We reconstructed 700 years of temporal and spatial aspects of fire activity with...

Data from: Global biogeography of mating system variation in seed plants

David A. Moeller, Ryan D. Briscoe Runquist, Annika M. Moe, Monica A. Geber, Carol Goodwillie, Pierre-Olivier Cheptou, Christopher G. Eckert, Elizabeth Elle, Mark O. Johnston, Susan Kalisz, Richard H. Ree, Risa D. Sargent, Mario Vallejo-Marin & Alice A. Winn
Latitudinal gradients in biotic interactions have been suggested as causes of global patterns of biodiversity and phenotypic variation. Plant biologists have long speculated that outcrossing mating systems are more common at low than high latitudes owing to a greater predictability of plant–pollinator interactions in the tropics; however, these ideas have not previously been tested. Here, we present the first global biogeographic analysis of plant mating systems based on 624 published studies from 492 taxa. We...

Multimodal and multifunctional signaling? – web reduction courtship behavior in a North American population of the false black widow spider

Andreas Fischer, Jamie-Lynne Varney, Gerhard Gries, Adam Blake, Stephen Takács & Xiang Goh
Males of widow spiders courting on the web of females engage in web reduction behavior which entails excising a section of the web, bundling it up, and wrapping it with their silk. Males of the false black widow spider, Steatoda grossa , in European populations also produce stridulatory courtship sound which has not yet been studied in their invaded North American range. Working with a North American population of S. grossa , we tested the...

Data from: Local interactions and their group-level consequences in flocking jackdaws

Hangjian Ling, Guillam E. McIvor, Kasper Van Der Vaart, Richard T. Vaughan, Alex Thornton & Nicholas T. Ouellette
As one of nature’s most striking examples of collective behaviour, bird flocks have attracted extensive research. However, we still lack an understanding of the attractive and repulsive forces that govern interactions between individuals within flocks and how these forces influence neighbours’ relative positions and ultimately determine the shape of flocks. We address these issues by analysing the three-dimensional movements of wild jackdaws (Corvus monedula) in flocks containing 2 to 338 individuals. We quantify the social...

Spectral data and R modeling code from: Polarized light sensitivity in Pieris rapae is dependent on both color and intensity

Adam Blake, Gina S. Hahn, Hayley Grey, Shelby A. Kwok, Deby McIntosh & Gerhard Gries
This dataset provides supplementary spectral data and the R code underlying the spectral sensitivy moding of female Pieris rapae photoreceptors used in the manuscript "Polarized light sensitivity in Pieris rapae is dependent on both color and intensity".

Disease-driven mass mortality event leads to widespread extirpation and variable recovery potential of a marine predator across the eastern Pacific

Sara Hamilton, Vienna Saccomanno, Walter Heady, Alyssa-Lois Gehman, Steve Lonhart, Rodrigo Beas-Luna, Fiona Francis, Lynn Lee, Laura Rogers-Bennett, Anne Salomon & Sarah Gravem
The prevalence of disease-driven mass mortality events is increasing, but our understanding of spatial variation in their magnitude, timing, and triggers are often poorly resolved. Here, we use a novel range-wide dataset comprised of 48,810 surveys to quantify how Sea Star Wasting Disease affected Pycnopodia helianthoides, the sunflower sea star, across its range from Baja California, Mexico to the Aleutian Islands, USA. We found that the outbreak occurred more rapidly, killed a greater percentage of...

Using GBIF to Demonstrate Colonial Legacies on Biodiversity Data

Ryan S. Mohammed, Melissa Kemp, Michelle J. LeFebvre, Alexis M. Mychajliw, Grace Turner, Kelly Fowler, Michael Pateman, Maria A. Nieves-Colón, Lanya Fanovich, Siobhan B. Cooke, Liliana M. Dávalos, Scott M. Fitzpatrick, Christina M. Giovas, Myles Stokowski & Ashley A. Wrean
Biologists recognize the Caribbean archipelago as a biodiversity hotspot and employ it for their research as a “natural laboratory”, but do not always appreciate that these ecosystems are in fact palimpsests shaped by multiple human cultures over millennia. We discuss two case studies of the Caribbean’s fragmented natural history collections, the effects of differing legislation and governance by the region’s multiple nation states. We use digital natural history specimen data from GBIF to demonstrate how...

Data from: Coleoptera associated with intermittent streams and their riparian zones in south coastal British Columbia

Chelsea J. Little & Zoey B. D. Schutz
Intermittent streams that periodically cease surface flow have long been understudied in ecology and underrepresented in conservation policy. However, they currently account for 30-50% of the global river network, and that number is rising due to anthropogenic water extraction, land-use change, and climate change. We explored the Coleoptera biodiversity of the south Pacific-coast region of British Columbia, Canada, using pitfall traps at perennial and naturally-intermittent stream reaches, in shoreline, dry streambed, and riparian habitats, in...

Interactive effects of multiscale diversification practices on farmland bird stress

Elissa Olimpi, Hallie Daly, Karina Garcia, Victoria Glynn, David Gonthier, Claire Kremen & Leithen M'Gonigle
Farmland diversification practices (i.e., methods used to produce food sustainably by enhancing biodiversity in cropping systems) are sometimes considered beneficial to both agriculture and biodiversity, but most studies of these practices rely on species richness, diversity, or abundance as a proxy for habitat quality. Biodiversity assessments may miss early clues that populations are imperiled when species presence does not imply persistence. Physiological stress indicators may help identify low-quality habitats before population declines occur. We explored...

Epigenetic induction may speed up or slow down speciation with gene flow: code and data

Philip Greenspoon, Hamish Spencer & Leithen M'Gonigle
Speciation is less likely to occur when there is gene flow between nascent species. Natural selection can oppose gene flow and promote speciation if there is variation in ecological conditions among the nascent species' locations. Previous theory on ecological speciation with gene flow has focused primarily on the role of genetic variation in ecological traits, largely neglecting the role of non-genetic inheritance or transgenerational plasticity. Here we present the simulation code and data from models...

Ecology and Evolution" The data comprises plant-pollinator interactions collected in three ecosystems (Oak Savannah, Shrub-Steppe and restored hedgerows) from British Columbia. These three vegetation types comprised three different studies. The average distance between sites within studies was 19km, 18km and 29km for the oak savannah, shrub-steppe and...

Data for: Occupancy–detection models with museum specimen data: Promise and pitfalls

Vaughn Shirey, Rassim Khelifa, Leithen M'Gonigle & Laura Melissa Guzman
Historical museum records provide potentially useful data for identifying drivers of change in species occupancy. However, because museum records are typically obtained via many collection methods, methodological developments are needed in order to enable robust inferences. Occupancy-detection models, a relatively new and powerful suite of statistical methods, are a potentially promising avenue because they can account for changes in collection effort through space and time. We use simulated datasets to identify how and when patterns...

Geographic homogenization but little net change in the local richness of Canadian butterflies

Jayme Lewthwaite & Arne Mooers
Aim: Recent studies have found that local-scale plots measured through time exhibit marked variation in the change in species richness. However, the overall effect often reveals no net change. Most studies thus far have been agnostic about the identities of the species lost/gained, as well as the processes that may lead to these changes. Generalist traits may be crucial in allowing species to colonize new plots or remain resilient in situ, whereas environmental filtering may...
