Data from: Do ecological communities disperse across biogeographic barriers as a unit?

Jordan D. Satler & Bryan C. Carstens
Biogeographic barriers have long been implicated as drivers of biological diversification, but how these barriers influence co-occurring taxa can vary depending on factors intrinsic to the organism and in their relationships with other species. Due to the interdependence among taxa, ecological communities present a compelling opportunity to explore how interactions among species may lead to a shared response to historical events. Here we collect single nucleotide polymorphism (SNP) data from five commensal arthropods associated with...

Data from: Habitat patch use by fishers in the deciduous forest-dominated landscape of the central Appalachian Mountains, USA

Hance Ellington E., Sean W. Gess, Erin L. Koen, Joe Duchamp, Matthew Lovallo, Matthew R. Dzialak, Jeffrey Larkin, Joseph E. Duchamp & Jeffery L. Larkin
Fishers (Pekania pennanti) are often associated with the coniferous and mixed forests of the northern United States and central Canada, and their ecology has been studied extensively in portions of their distributional range. Recently, natural range expansion and reintroductions have led to recolonization by fishers of portions of the central Appalachian Mountains, USA, where deciduous forest is the dominant vegetation type. We used noninvasive hair snare surveys and microsatellite genetic analysis to detect fishers in...

Data from: Alteration of plant-species assemblages can decrease the transmission potential of malaria mosquitoes

Babak Ebrahimi, Bryan T. Jackson, Julie L. Guseman, Colin M. Przybylowicz, Christopher M. Stone & Woodbridge A. Foster
1. Knowledge of the link between a vector population’s pathogen-transmission potential and its biotic environment can generate more realistic forecasts of disease risk due to environmental change. It also can promote more effective vector control by both conventional and novel means 2. The present study assessed the effect of particular plant-species assemblages differing in nectar production on components of the vectorial capacity of the mosquito Anopheles gambiae s.s., an important vector of African malaria. 3....

Data from: An echinoderm Lagerstätte from the Upper Ordovician (Katian), Ontario: taxonomic re-evaluation and description of new dicyclic camerate crinoids

Selina R. Cole, William I. Ausich, David F. Wright & Joseph M. Koniecki
The Upper Ordovician (lower Katian) Bobcaygeon and Verulam formations from the Lake Simcoe region of Ontario contain a highly diverse echinoderm assemblage that is herein recognized as a Konservat-Lagerstätte. Although fossil crinoids have long been recognized from these formations, the fauna has not received a comprehensive taxonomic evaluation since Springer’s classic 1911 monograph. Recent extensive collection and preparation of new material from the Bobcaygeon and Verulam formations near Brechin, Ontario recovered numerous exceptionally preserved crinoid...

Data from: Persistent anthrax as a major driver of wildlife mortality in a tropical rainforest

Constanze Hoffmann, Fee Zimmermann, Roman Biek, Hjalmar Kuehl, Kathrin Nowak, Roger Mundry, Anthony Agbor, Samuel Angedakin, Mimi Arandjelovic, Anja Blankenburg, Gregory Brazolla, Katherine Corogenes, Emmanuel Couacy-Hymann, Tobias Deschner, Paula Dieguez, Karsten Dierks, Ariane Düx, Susann Dupke, Henk Eshuis, Pierre Formenty, Yisa Ginath Yuh, Annemarie Goedmakers, Jan Gogarten, Anne-Céline Granjon, Scott McGraw … & Fabian Leendertz
Anthrax is a globally significant animal disease and zoonosis. Despite this, current knowledge of anthrax ecology is largely limited to arid ecosystems, where outbreaks are most commonly reported. We reveal cryptic the dynamics of an anthrax causing agent, Bacillus cereus biovar anthracis, in a tropical rainforest with severe consequences for local wildlife communities. Using data and samples collected over three decades we found that rainforest anthrax is a persistent and widespread cause of death for...

Data from: Effects of overexpressing a native gene encoding 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) on glyphosate resistance in Arabidopsis thaliana

Xiao Yang, Zachery T. Beres, Lin Jin, Jason T. Parrish, Wanying Zhao, David Mackey & Allison A. Snow
Widespread overuse of the herbicide glyphosate, the active ingredient in RoundUp®, has led to the evolution of glyphosate-resistant weed biotypes, some of which persist by overproducing the herbicide's target enzyme, 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS). EPSPS is a key enzyme in the shikimic acid pathway for biosynthesis of aromatic amino acids, lignin, and defensive compounds, but little is known about how overproducing EPSPS affects downstream metabolites, growth, or lifetime fitness in the absence of glyphosate. We are...

Data from: Influence of historical land use and modern agricultural expansion on the spatial and ecological divergence of sugarcane borer, Diatraea saccharalis (Lepidoptera: Crambidae) in Brazil

Vitor A.C. Pavinato, Andrew P. Michel, Jaqueline B. De Campos, Celso Omoto & Maria I. Zucchi
Human-mediated changes in landscapes can facilitate niche expansion and accelerate the adaptation of insect species. The interaction between the evolutionary history of the sugarcane borer, Diatraea saccharalis Fabricius, and historical and modern agricultural activity in Brazil shaped its spatial genetic structure, facilitating ecological divergence and incipient host-shifting. Based on microsatellite data, STRUCTURE analyses identified two (K=2) and three (K=3) significant genetic clusters that corresponded to: a) a strong signal of spatial genetic structure and, b)...

Data from: PHRAPL: phylogeographic inference using approximate likelihoods

Nathan D. Jackson, Ariadna E. Morales, Bryan C. Carstens & Brian C. O'Meara
The demographic history of most species is complex, with multiple evolutionary processes combining to shape the observed patterns of genetic diversity. To infer this history, the discipline of phylogeography has (to date) used models that simplify the historical demography of the focal organism, for example by assuming or ignoring ongoing gene flow between populations or by requiring a priori specification of divergence history. Since no single model incorporates every possible evolutionary process, researchers rely on...

Data from: Planting of neonicotinoid-treated maize poses risks for honey bees and other non-target organisms over a wide area without consistent crop yield benefit

Christian H. Krupke, Jeffrey D. Holland, Elizabeth Y. Long & Brian D. Eitzer
Neonicotinoid insecticides are routinely used as seed treatments on most grain and oilseed crops in the USA, yet the extent and likelihood of spread of insecticide residues during planting has not previously been quantified. Honey bees, Apis mellifera, are highly mobile and highly sensitive to neonicotinoid residues, presenting an opportunity to estimate non-target exposures to neonicotinoids in mobile insects. We measured neonicotinoid dust drift during maize sowing and used sites of maize fields, apiary locations...

Data from: Genomic signals of selection predict climate-driven population declines in a migratory bird

Rachael A. Bay, Ryan J. Harrigan, Vinh Le Underwood, H. Lisle Gibbs, Thomas B. Smith & Kristen C. Ruegg
The ongoing loss of biodiversity caused by rapid climatic shifts requires accurate models for predicting species’ responses. Despite evidence that evolutionary adaptation could mitigate climate change impacts, evolution is rarely integrated into predictive models. Integrating population genomics and environmental data, we identified genomic variation associated with climate across the breeding range of the migratory songbird, yellow warbler (Setophaga petechia). Populations requiring the greatest shifts in allele frequencies to keep pace with future climate change have...

Data from: Aboveground biomass is driven by mass-ratio effects and stand structural attributes in a temperate deciduous forest

Alexander T. Fotis, Stephen J. Murphy, Raleigh D. Ricart, Meghna Krishnadas, James Whitacre, John W. Wenzel, Simon A. Queenborough & Liza S. Comita
1.Forest ecosystems are critical for the global regulation of carbon (C), a substantial portion of which is stored in aboveground biomass (AGB). While it is well understood that taxonomic and functional composition, stand structure, and environmental gradients influence spatial variation in AGB, the relative strengths of these drivers at landscape-scales has not been investigated in temperate forests. Furthermore, when biodiversity enhances C storage, it is unclear whether it is through mass-ratio effects (i.e., the dominant...

Data from: Batocrinidae (Crinoidea) from the lower Mississippian (lower Viséan) Fort Payne Formation of Kentucky, Tennessee, and Alabama: systematics, geographic occurrences, and facies distribution

William I. Ausich, Elizabeth C. Rhenberg & Davld L. Meyer
The Batocrinidae are characteristic faunal elements in lower Mississippian shallow-marine settings in North America. Recent delineation of objectively defined genera allows a reexamination of batocrinid species and their distribution in the Fort Payne Formation (early Viséan, late Osagean), a well-studied array of carbonate and siliciclastic facies. The Fort Payne batocrinid fauna has fourteen species assigned to six genera, plus hybrid specimens. Magnuscrinus spinosus (Miller and Gurley, 1895a) is reassigned to its original placement in Eretmocrinus....

Data from: Combining allele frequency and tree-based approaches improves phylogeographic inference from natural history collections

Megan Ruffley, Megan L. Smith, Anahi Espindola, Bryan C. Carstens, Jack Sullivan & David C. Tank
Model selection approaches in phylogeography have allowed researchers to evaluate the support for competing demographic histories, which provides a mode of inference and a measure of uncertainty in understanding climatic and spatial influences on intraspecific diversity. Here, to rank all models in the comparison set, and determine what proportion of the total support the top-ranked model garners, we conduct model selection using two analytical approaches –allele frequency-based, implemented in fastsimcoal2, and gene tree-based, implemented in...

Data from: Primers for Castilleja and their utility across Orobanchaceae: II. Single-copy nuclear loci

Maribeth Latvis, Sarah J. Jacobs, Sebastian M. E. Mortimer, Melissa Richards, Paul D. Blischak, Sarah Mathews & David C. Tank
Premise of the study: We developed primers targeting nuclear loci in Castilleja with the goal of reconstructing the evolutionary history of this challenging clade. These primers were tested across other major clades in Orobanchaceae to assess their broader utility. Methods and Results: We assembled low-coverage genomes for three taxa in Castilleja and developed primer combinations for the single-copy conserved ortholog set (COSII) and the pentatricopeptide repeat (PPR) gene family. These primer combinations were designed to...

Data from: Within-group relatedness is correlated with colony-level social structure and reproductive sharing in a social fish.

Jennifer K. Hellmann, Michael G. Sovic, H. Lisle Gibbs, Adam R. Reddon, Constance M. O'Connor, Isaac Y. Ligocki, Susan Marsh-Rollo, Sigal Balshine & Ian M. Hamilton
In group-living species, the degree of relatedness among group members often governs the extent of reproductive sharing, cooperation and conflict within a group. Kinship among group members can be shaped by the presence and location of neighbouring groups, as these provide dispersal or mating opportunities that can dilute kinship among current group members. Here, we assessed how within-group relatedness varies with the density and position of neighbouring social groups in Neolamprologus pulcher, a colonial and...

Data from: Distance-dependent seedling mortality and long-term spacing dynamics in a neotropical forest community

Stephen J. Murphy, Thorsten Wiegand & Liza S. Comita
Negative distance dependence (NDisD), or reduced recruitment near adult conspecifics, is thought to explain the astounding diversity of tropical forests. While many studies show greater mortality at near vs. far distances from adults, these studies do not seek to track changes in the peak seedling curve over time, thus limiting our ability to link NDisD to coexistence. Using census data collected over 12 years from central Panama in conjunction with spatial mark-connection functions, we show...

Data from: Recent lineage diversification in a venomous snake through dispersal across the Amazon River

H. Lisle Gibbs, Michael Sovic, Diana Amazonas, Hippocrates Chalkidis, David Salazar-Valenzuela & Ana M. Moura-Da-Silva
Identifying the evolutionary and ecological mechanisms that drive lineage diversification in the species-rich tropics is of broad interest to evolutionary biologists. Here, we use phylogeographic and demographic analyses of genomic scale RADseq data to assess the impact of a large geographic feature, the Amazon River, on lineage formation in a venomous pitviper, Bothrops atrox. We compared genetic differentiation in samples from four sites near Santarem, Brazil that spanned the Amazon and represented major habitat types....

Data from: Disparid and hybocrinid crinoids (Echinodermata) from the Upper Ordovician (lower Katian) Brechin Lagerstätte of Ontario

William I. Ausich, David F. Wright, Selina R. Cole & Joseph M. Koniecki
The Brechin Lagerstätte (Katian, Ordovician) from the Lake Simcoe region of Ontario, Canada, contains a diverse array of echinoderms. Here, we describe seven disparid and two hybocrinid crinoids (Subclass Pentacrinoidea, Infraclass Inadunata), including a new disparid species belonging to the Anomalocrinidae (Order Homocrinida). In total, the disparids include Anomalocrinus astrictus n. sp.; Cremacrinus guttenbergensis Kolata, 1975; Cremacrinus inaequalis Billings, E., 1859; Daedalocrinus bellevillensis Billings, W.R., 1883; Eustenocrinus springeri Ulrich, 1925; Iocrinus trentonensis Walcott, 1883; and...

Data from: Morphological support for a clade comprising two vermiform mite lineages: Eriophyoidea (Acariformes) and Nematalycidae (Acariformes)

Samuel J. Bolton, Philipp E. Chetverikov & Hans Klompen
A morphology-based parsimony analysis (50 taxa; 110 characters) focused on relationships among basal acariform mites places Eriophyoidea (formerly in Trombidiformes) within Nematalycidae (Sarcoptiformes). Although both taxa have worm-like bodies, this grouping is unexpected because it combines obligate plant inhabitants (Eriophyoidea) with obligate inhabitants of deep-soil or mineral regolith (Nematalycidae sensu stricto). The Eriophyoidea + Nematalycidae clade, which is strongly supported (Bremer =5; bootstrap =85%), retains moderately good support (Bremer=3; bootstrap=66%) when three ratio-based characters pertaining...

Data from: Spatial and temporal components of induced plant responses in the context of herbivore life history and impact on host

Charles J. Mason, Caterina Villari, Ken Keefover-Ring, Stephanie Jagemann, Jun Zhu, Pierluigi Bonello & Kenneth F. Raffa
Plants defend against herbivores and pathogens through integrated constitutive and induced defenses. Induced responses may be expressed locally or tissue/plant-wide, i.e. systemically, and may also be primed for subsequent attack. Although the elicitation and efficacy of induced responses are increasingly well-characterized, we have little understanding of how timing and within-plant spatial patterns of induced defenses relate to different herbivore behaviors and selective pressures. We used interactions between pines and their major mortality agents, native bark...

Data from: Walking with wider steps changes foot placement control, increases kinematic variability and does not improve linear stability

Jennifer A. Perry & Manoj Srinivasan
Walking humans respond to pulls or pushes on their upper body by changing where they place their foot on the next step. Usually, they place their foot further along the direction of the upper body perturbation. Here, we examine how this foot placement response is affected by the average step width during walking. We performed experiments with humans walking on a treadmill, both normally and at five different prescribed step widths. We prescribed step widths...

Data from: Demographic model selection using random forests and the site frequency spectrum

Megan L. Smith, Megan Ruffley, Anahí Espindola, David C. Tank, Jack Sullivan & Bryan C. Carstens
Phylogeographic data sets have grown from tens to thousands of loci in recent years, but extant statistical methods do not take full advantage of these large data sets. For example, approximate Bayesian computation (ABC) is a commonly used method for the explicit comparison of alternate demographic histories, but it is limited by the “curse of dimensionality” and issues related to the simulation and summarization of data when applied to next-generation sequencing (NGS) data sets. We...

Data from: Cytochrome P450 diversification and hostplant utilization patterns in specialist and generalist moths: birth, death, and adaptation

Bernarda Calla, Katherine Noble, Reed M. Johnson, Kimberly K. O. Walden, Mary A. Schuler, Hugh M. Robertson & May R. Berenbaum
Across insect genomes, the size of the cytochrome P450 monooxygenase (CYP) gene superfamily varies widely. CYPome size variation has been attributed to reciprocal adaptive radiations in insect detoxification genes in response to plant biosynthetic gene radiations driven by coevolution between herbivores and their chemically defended hostplants. Alternatively, variation in CYPome size may be due to random “birth and death” processes, whereby exponential increase via gene duplications is limited by random decay via gene death or...

Data from: Landscape genetic analyses reveal fine-scale effects of forest fragmentation in an insular tropical bird

Aurélie Khimoun, William Peterman, Cyril Eraud, Bruno Faivre, Nicolas Navarro & Stéphane Garnier
Within the framework of landscape genetics, resistance surface modelling is particularly relevant to explicitly test competing hypotheses about landscape effects on gene flow. To investigate how fragmentation of tropical forest affects population connectivity in a forest specialist bird species, we optimized resistance surfaces without a priori specification, using least-cost (LCP) or resistance (IBR) distances. We implemented a two-step procedure in order (i) to objectively define the landscape thematic resolution (level of detail in classification scheme...
