Data from: Isolation by resistance across a complex coral reef seascape

Luke Thomas, W. Jason Kennington, Michael Stat, Shaun P. Wilkinson, Jonathan T. Kool & Gary A. Kendrick
A detailed understanding of the genetic structure of populations and an accurate interpretation of processes driving contemporary patterns of gene flow are fundamental to successful spatial conservation management. The field of seascape genetics seeks to incorporate environmental variables and processes into analyses of population genetic data to improve our understanding of forces driving genetic divergence in the marine environment. Information about barriers to gene flow (such as ocean currents) is used to define a resistance...

Data from: Assessing vertebrate biodiversity in a kelp forest ecosystem using environmental DNA

Jesse A. Port, James L. O'Donnell, Ofelia C. Romero-Maraccini, Paul R. Leary, Steven Y. Litvin, Kerry J. Nickols, Kevan M. Yamahara & Ryan P. Kelly
Preserving biodiversity is a global challenge requiring data on species’ distribution and abundance over large geographic and temporal scales. However, traditional methods to survey mobile species’ distribution and abundance in marine environments are often inefficient, environmentally destructive, or resource-intensive. Metabarcoding of environmental DNA (eDNA) offers a new means to assess biodiversity and on much larger scales, but adoption of this approach for surveying whole animal communities in large, dynamic aquatic systems has been slowed by...

Data from: \"Identification of SNP markers for the endangered Ugandan red colobus (Procolobus rufomitratus tephrosceles) using RAD sequencing\" in Genomic Resources Notes accepted 1 December 2014 to 31 January 2015

Maria Jose Ruiz Lopez, Tony L. Goldberg, Colin A. Chapman, Patrick A. Omeja, James H. Jones, William M. Switzer, Paul D. Etter, Eric A. Johnson & Nelson Ting
Despite dramatic growth in the field of primate genomics over the past decade, studies of primate population and conservation genomics in the wild have been hampered due to the difficulties inherent in studying non-model organisms and endangered species, such as lack of a reference genome and current challenges in de novo primate genome assembly. Here, we used Restriction-site Associated DNA (RAD) sequencing to develop a population-based SNP panel for the Ugandan red colobus (P. rufomitratus...

Data from: The role of transcriptome resilience in resistance of corals to bleaching

Francois O. Seneca & Stephen R. Palumbi
Wild populations increasingly experience extreme conditions as climate change amplifies environmental variability. How individuals respond to environmental extremes determines the impact of climate change overall. The variability of response from individual to individual can represent the opportunity for natural selection to occur as a result of extreme conditions. Here, we experimentally replicated the natural exposure to extreme temperatures of the reef lagoon at Ofu Island (American Samoa), where corals can experience severe heat stress during...

Data from: Transcriptome sequencing reveals both neutral and adaptive genome dynamics in a marine invader

Carolyn K. Tepolt & S. R. Palumbi
Species invasions cause significant ecological and economic damage, and genetic information is important to understanding and managing invasive species. In the ocean, many invasive species have high dispersal and gene flow, lowering the discriminatory power of traditional genetic approaches. High-throughput sequencing holds tremendous promise for increasing resolution and illuminating the relative contributions of selection and drift in marine invasion, but has not yet been used to compare the diversity and dynamics of a high-dispersal invader...

Data from: Genetic structure in village dogs reveals a Central Asian domestication origin

Laura M. Shannon, Ryan H. Boyko, Marta Castelhano, Elizabeth Corey, Jessica J. Hayward, Corin McLean, Michelle E. White, Mounir Abi Said, Baddley A. Anita, Nono Bondjengo Ikombe, Jorge Calero, Ana Galov, Marius Hedimbi, Bulu Imam, Rajashree Khalap, Douglas Lally, Andrew Masta, Kyle C. Oliveira, Lucía Pérez, Julia Randall, Nguyen Minh Tam, Francisco J. Trujillo-Cornejo, Carlos Valeriano, Nathan B. Sutter, Rory J. Todhunter … & Adam R. Boyko
Dogs were the first domesticated species, originating at least 15,000 y ago from Eurasian gray wolves. Dogs today consist primarily of two specialized groups—a diverse set of nearly 400 pure breeds and a far more populous group of free-ranging animals adapted to a human commensal lifestyle (village dogs). Village dogs are more genetically diverse and geographically widespread than purebred dogs making them vital for unraveling dog population history. Using a semicustom 185,805-marker genotyping array, we...

Data from: Tradeoffs between three forest ecosystem services across the state of New Hampshire, USA: timber, carbon, and albedo

David A. Lutz, Elizabeth A. Burakowski, Mackenzie B. Murphy, Mark E. Borsuk, Rebecca M. Niemiec & Richard B. Howarth
Forests are more frequently being managed to store and sequester carbon for the purposes of climate change mitigation. Generally, this practice involves long-term conservation of intact mature forests and/or reductions in the frequency and intensity of timber harvests. However, incorporating the influence of forest surface albedo often suggests that long rotation lengths may not always be optimal in mitigating climate change in forests characterized by frequent snowfall. To address this, we investigated tradeoffs between three...

Data from: Effects of spatial scale of sampling on food web structure

Spencer A. Wood, Roly Russell, Dieta Hanson, Richard J. Williams & Jennifer A. Dunne
This study asks whether the spatial scale of sampling alters structural properties of food webs and whether any differences are attributable to changes in species richness and connectance with scale. Understanding how different aspects of sampling effort affect ecological network structure is important for both fundamental ecological knowledge and the application of network analysis in conservation and management. Using a highly resolved food web for the marine intertidal ecosystem of the Sanak Archipelago in the...

Data from: Cell signaling-based classifier predicts response to induction therapy in elderly patients with acute myeloid leukemia

Alessandra Cesano, Cheryl L. Willman, Kenneth J. Kopecky, Urte Gayko, Santosh Putta, Brent Louie, Matt Westfall, Norman Purvis, David C. Spellmeyer, Carol Marimpietri, Aileen C. Cohen, James Hackett, Jing Shi, Michael G. Walker, Zhuoxin Sun, Elisabeth Paietta, Martin S. Tallman, Larry D. Cripe, Susan Atwater, Frederick R. Appelbaum & Jerald P. Radich
Single-cell network profiling (SCNP) data generated from multi-parametric flow cytometry analysis of bone marrow (BM) and peripheral blood (PB) samples collected from patients >55 years old with non-M3 AML were used to train and validate a diagnostic classifier (DXSCNP) for predicting response to standard induction chemotherapy (complete response [CR] or CR with incomplete hematologic recovery [CRi] versus resistant disease [RD]). SCNP-evaluable patients from four SWOG AML trials were randomized between Training (N = 74 patients...

Data from: Climate mediates the effects of disturbance on ant assemblage structure

Heloise Gibb, Nathan J. Sanders, Robert R. Dunn, Simon Watson, Manoli Photakis, Silvia Abril, Alan N. Andersen, Elena Angulo, Inge Armbrecht, Xavier Arnan, Fabricio B. Baccaro, Tom R. Bishop, Raphael Boulay, Cristina Castracani, Israel Del Toro, Thibaut Delsinne, Mireia Diaz, David A. Donoso, Martha L. Enríquez, Tom M. Fayle, Donald H. Feener, Matthew C. Fitzpatrick, Crisanto Gómez, Donato A. Grasso, Sarah Groc … & C. Gomez
Many studies have focused on the impacts of climate change on biological assemblages, yet little is known about how climate interacts with other major anthropogenic influences on biodiversity, such as habitat disturbance. Using a unique global database of 1128 local ant assemblages, we examined whether climate mediates the effects of habitat disturbance on assemblage structure at a global scale. Species richness and evenness were associated positively with temperature, and negatively with disturbance. However, the interaction...

Data from: Genetic isolation between two recently diverged populations of a symbiotic fungus

Sara Branco, Pierre Gladieux, Christopher E. Ellison, Alan Kuo, Kurt LaButii, Anna Lipzen, Igor V. Grigoriev, Hui-Ling Liao, Rytas Vilgalys, Kabir G. Peay, John W. Taylor, Thomas D. Bruns & Kurt LaButti
Fungi are an omnipresent and highly diverse group of organisms, making up a significant part of eukaryotic diversity. Little is currently known about the drivers of fungal population differentiation and subsequent divergence of species, particularly in symbiotic, mycorrhizal fungi. Here, we investigate the population structure and environmental adaptation in Suillus brevipes (Peck) Kuntze, a wind-dispersed soil fungus that is symbiotic with pine trees. We assembled and annotated the reference genome for Su. brevipes and resequenced...

Data from: \"De novo assembly transcriptome for the rostrum dace (Leuciscus burdigalensis, Cyprinidae: fish) naturally infected by a copepod ectoparasite\" in Genomic Resources Notes accepted 1 December 2014 to 31 January 2015

Olivier Rey, Géraldine Loot, Olivier Bouchez, Simon Blanchet, Maria Jose Ruiz-Lopez, Nelson Ting, Paul D. Etter, Eric A. Johnson, Tony L. Goldberg, Colin A. Chapman, James H. Jones, Patrick A. Omeja & William M. Switzer
The emergence of pathogens represents substantial threats to public health, livestock, domesticated animals, and biodiversity. How wild populations respond to emerging pathogens has generated a lot of interest in the last two decades. With the recent advent of high-throughput sequencing technologies it is now possible to develop large transcriptomic resources for non-model organisms, hence allowing new research avenues on the immune responses of hosts from a large taxonomic spectra. We here focused on a wild...

Data from: Genomic variation in recently collected maize landraces from Mexico

María Clara Arteaga, Alejandra Moreno-Letelier, Alicia Mastretta-Yanes, Alejandra Vázquez-Lobo, Alejandra Breña-Ochoa, Andrés Moreno-Estrada, Luis E. Eguiarte & Daniel Piñero
The present dataset comprises 36,931 SNPs genotyped in 46 maize landraces native to Mexico as well as the teosinte subspecies Zea maiz ssp. Parviglumis and ssp. Mexicana. These landraces were collected directly from farmers mostly between 2006 and 2010. We accompany these data with a short description of the variation within each landrace, as well as maps, principal component analyses and neighbor joining trees showing the distribution of the genetic diversity relative to landrace, geographical...

Data from: Large wildlife removal drives immune defense increases in rodents

Hillary S. Young, Rodolfo Dirzo, Kristofer M. Helgen, Douglas J. McCauley, Charles L. Nunn, Paul Snyder, Kari E. Veblen, Serena Zhao & Vanessa O. Ezenwa
Anthropogenic disturbances involving land use change, climate disruption, pollution, and invasive species have been shown to impact immune function of wild animals. These immune changes have direct impacts on the fitness of impacted animals and, also, potentially indirect effects on other species and on ecological processes, notably involving the spread of infectious disease. Here, we investigate whether the selective loss of large wildlife can also drive changes in immune function of other consumer species. Using...

Data from: Genomic sequencing reveals historical, demographic and selective factors associated with the diversification of the fire-associated fungus Neurospora discreta

Pierre Gladieux, Benjamin A. Wilson, Fanny Perraudeau, Liliam A. Montoya, David Kowbel, Christopher Hann-Soden, Monika Fischer, Iman Sylvain, David J. Jacobson & John W. Taylor
Delineating microbial populations, discovering ecologically relevant phenotypes and identifying migrants, hybrids or admixed individuals have long proved notoriously difficult, thereby limiting our understanding of the evolutionary forces at play during the diversification of microbial species. However, recent advances in sequencing and computational methods have enabled an unbiased approach whereby incipient species and the genetic correlates of speciation can be identified by examining patterns of genomic variation within and between lineages. We present here a population...

Data from: Effects of increased flight on the energetics and life history of the butterfly Speyeria mormonia

Kristjan Niitepõld & Carol L. Boggs
Movement uses resources that may otherwise be allocated to somatic maintenance or reproduction. How does increased energy expenditure affect resource allocation? Using the butterfly Speyeria mormonia, we tested whether experimentally increased flight affects fecundity, lifespan or flight capacity. We measured body mass (storage), resting metabolic rate and lifespan (repair and maintenance), flight metabolic rate (flight capacity), egg number and composition (reproduction), and food intake across the adult lifespan. The flight treatment did not affect body...

Data from: Characterizing driver-response relationships in marine pelagic ecosystems for improved ocean management

Mary E. Hunsicker, Carrie V. Kappel, Kimberly A. Selkoe, Benjamin S. Halpern, Courtney Scarborough, Lindley Mease & Alisan Amrhein
Scientists and resources managers often use methods and tools that assume ecosystem components respond linearly to environmental drivers and human stressor. However, a growing body of literature demonstrates that many relationships are non-linear, where small changes in a driver prompt a disproportionately large ecological response. Here we aim to provide a comprehensive assessment of the relationships between drivers and ecosystem components to identify where and when non-linearities are likely to occur. We focus our analyses...

Data from: Forage species in predator diets: synthesis of data from the California Current

Amber I. Szoboszlai, Julie A. Thayer, Spencer A. Wood, William J. Sydeman & Laura E. Koehn
Characterization of the diets of upper-trophic pelagic predators that consume forage species is a key ingredient in the development of ecosystem-based fishery management plans, conservation of marine predators, and ecological and economic modeling of trophic interactions. Here we present the California Current Predator Diet Database (CCPDD) for the California Current region of the Pacific Ocean over the past century, assimilating over 190 published records of predator food habits for over 100 predator species and 32...

Data from: Transcriptome dynamics of the stomatal lineage: birth, amplification, and termination of a self-renewing population

Jessika Adrian, Jessica Chang, Catherine E. Ballenger, Bastiaan O. R. Bargmann, Julien Alassimone, Kelli A. Davies, On Sun Lau, Juliana L. Matos, Charles Hachez, Amy Lanctot, Anne Vatén, Kenneth D. Birnbaum & Dominique C. Bergmann
Developmental transitions can be described in terms of morphology and the roles of individual genes, but also in terms of global transcriptional and epigenetic changes. Temporal dissections of transcriptome changes, however, are rare for intact, developing tissues. We used RNA sequencing and microarray platforms to quantify gene expression from labeled cells isolated by fluorescence-activated cell sorting to generate cell-type-specific transcriptomes during development of an adult stem-cell lineage in the Arabidopsis leaf. We show that regulatory...

Data from: Post-dispersal seed recovery by animals: is it a plant- or an animal-driven process?

Ramón Perea, Rodolfo Dirzo, Alfonso San Miguel & Luis Gil
The ability of animals to find and consume hoarded seeds (i.e. seed recovery) is a key stage within the seed dispersal process. However, the ecology of seed recovery is still poorly understood. Here, we analyze the factors controlling seed recovery by scatter-hoarding rodents in an oak-dominated temperate forest. We examined the relative importance of intrinsic seed traits (i.e. plant-driven) and extrinsic seed factors (i.e. animal-driven) on the probability of seed recovery. We found that seed...

Data from: In an age of open access to research policies: physician and public health NGO staff research use and policy awareness

Laura L. Moorhead, Cheryl Holzmeyer, Lauren A. Maggio, Ryan M. Steinberg, John M. Willinsky & John Willinsky
Introduction: Through funding agency and publisher policies, an increasing proportion of the health sciences literature is being made open access. Such an increase in access raises questions about the awareness and potential utilization of this literature by those working in health fields. Methods: A sample of physicians (N=336) and public health non-governmental organization (NGO) staff (N=92) were provided with relatively complete access to the research literature indexed in PubMed, as well as access to the...

Data from: Pervasive and strong effects of plants on soil chemistry: a meta-analysis of individual plant ‘Zinke’ effects

Bonnie G. Waring, Leonor Álvarez-Cansino, Kathryn E. Barry, Kristen K. Becklund, Sarah Dale, Maria G. Gei, Adrienne B. Keller, Omar R. Lopez, Lars Markesteijn, Scott Mangan, Charlotte E. Riggs, Maria Elizabeth Rodríguez-Ronderos, R. Max Segnitz, Stefan A. Schnitzer & Jennifer S. Powers
Plant species leave a chemical signature in the soils below them, generating fine-scale spatial variation that drives ecological processes. Since the publication of a seminal paper on plant-mediated soil heterogeneity by Paul Zinke in 1962, a robust literature has developed examining effects of individual plants on their local environments (individual plant effects). Here, we synthesize this work using meta-analysis to show that plant effects are strong and pervasive across ecosystems on six continents. Overall, soil...

Data from: Ecosystem response to interventions: lessons from restored and created wetland ecosystems

David Moreno-Mateos, Paula Meli, María Isabel Vara-Rodriguez & James Aronson
1. Current efforts to restore and create ecosystems require greater understanding of ecosystems’ responses to commonly used physical and biological intervention approaches to overcome ecological and technological limitations. 2. We estimated effect sizes from measurements of biotic assemblage structure and biogeochemical functions at 628 restored and created wetlands globally, in comparison with 499 reference wetlands. We studied the recovery trajectories of wetlands where different restoration or creation approaches were used under different environmental settings. 3....

Data from: Comparative population genomics of latitudinal variation in D. simulans and D. melanogaster

Heather E. Machado, Alan O. Bergland, Emily L. Behrman, Katherine R. O'Brien, Paul S. Schmidt & Dmitri A. Petrov
Examples of clinal variation in phenotypes and genotypes across latitudinal transects have served as important models for understanding how spatially varying selection and demographic forces shape variation within species. Here we examine the selective and demographic contributions to latitudinal variation through the largest comparative genomic study to date of Drosophila simulans and D. melanogaster, with genomic sequence data from 382 individual fruit flies, collected across a spatial transect of 19 degrees latitude and at multiple...

Data from: Secondary contact and local adaptation contribute to genome-wide patterns of clinal variation in Drosophila melanogaster

Alan O. Bergland, Ray Tobler, Josefa Gonzalez, Paul Schmidt, Dimitri A. Petrov & Dmitri Petrov
Populations arrayed along broad latitudinal gradients often show patterns of clinal variation in phenotype and genotype. Such population differentiation can be generated and maintained by both historical demographic events and local adaptation. These evolutionary forces are not mutually exclusive and can in some cases produce nearly identical patterns of genetic differentiation among populations. Here, we investigate the evolutionary forces that generated and maintain clinal variation genome-wide among populations of Drosophila melanogaster sampled in North America...
