Data from: Genomic architecture of adaptive color pattern divergence and convergence in Heliconius butterflies

Megan A. Supple, Heather M. Hines, Kanchon K. Dasmahapatra, James J. Lewis, Dahlia M. Nielsen, Christine Lavoie, David A. Ray, Camilo Salazar, W. Owen McMillan & Brian A. Counterman
Identifying the genetic changes driving adaptive variation in natural populations is key to understanding the origins of biodiversity. The mosaic of mimetic wing patterns in Heliconius butterflies makes an excellent system for exploring adaptive variation using next-generation sequencing. In this study, we use a combination of techniques to annotate the genomic interval modulating red color pattern variation, identify a narrow region responsible for adaptive divergence and convergence in Heliconius wing color patterns, and explore the...

Data from: High precipitation and seeded species competition reduce seeded shrub establishment during dryland restoration

Matthew J. Rinella, Darcy H. Hammond, Ana-Elisa M. Bryant & Brian J. Kozar
Drylands comprise 40% of Earth's land mass and are critical to food security, carbon sequestration, and threatened and endangered wildlife. Exotic weed invasions, overgrazing, energy extraction, and other factors have degraded many drylands, and this has placed an increased emphasis on dryland restoration. The increased restoration focus has generated a wealth of experience, innovations and empirical data, yet the goal of restoring diverse, native, dryland plant assemblages composed of grasses, forbs, and shrubs has generally...

Data from: Response of non-grassland avian guilds to adjacent herbaceous field buffers: testing hypotheses about configuration of targeted conservation practices in agricultural landscapes

Samuel K. Riffell, Adrian P. Monroe, James A. Martin, Kristine O. Evans, , Mark D. Smith & Loren W. Burger
1. A substantial part of the world's land base is dominated by agriculture, and forest habitat often consists of discrete patches of forest and linear woody corridors. These natural components provide habitat for some forest birds, but make conservation of these species difficult. In-field practices applied outside forest patches, such as specific juxtapositions of herbaceous field buffers adjacent to forest habitat, could increase avian diversity contributions of existing forest without creation of additional forest habitat....

Data from: Sulfur resistance of Ce-Mn/TiO2 catalysts for low-temperature NH3–SCR

Quan Xu, Wenjing Yang, Shitong Cui, Jason Street & Yan Luo
Ce-Mn/TiO2 catalyst prepared using a simple impregnation method demonstrated a better low-temperature selective catalytic reduction of NO with NH3 (NH3-SCR) activity in comparison with the sol-gel method. The Ce-Mn/TiO2 catalyst loading with 20% Ce had the best low-temperature activity and achieved a NO conversion rate higher than 90% at 140-260°C with a 99.7% NO conversion rate at 180 °C. The Ce-Mn/TiO2 catalyst only had a 6% NO conversion rate decrease after 100 ppm of SO2...

Data from: Degradation of key photosynthetic genes in the critically endangered semi-aquatic flowering plant Saniculiphyllum guangxiense (Saxifragaceae)

Ryan Folk
Plastid gene loss and pseudogenization has been widely documented in parasitic and mycoheterotrophic plants, which have relaxed selective constraints on photosynthetic function. More enigmatic are sporadic reports of degradation and loss of important photosynthesis genes in lineages thought to be fully photosynthetic. Here we report the complete plastid genome of Saniculiphyllum guangxiense, a critically endangered and phylogenetically isolated plant lineage, along with genomic evidence of reduced chloroplast function. We also report 22 additional plastid genomes...

Data from: Mowing effects on woody stem density and woody and herbaceous vegetation heights along Mississippi highway right-of-ways

Edward Entsminger, Jeanne Jones, John Guyton, Bruce Leopold & Bronson Strickland
Roadside right-of-ways (ROWs) undergo regular disturbances such as mowing, maintenance, wrecks, and road developments, which affect soils, groundwater, surface hydrology, and the composition of vegetation. Roadsides can provide and support an environment for diverse plant communities, but management practices have reduced native grasses, wildflowers, and woody plants. Woody plants are not desirable for traffic safety, maintenance, and visibility along road ROWs. Therefore, the objectives of this study were to investigate effects of roadside mowing frequency...

Paraphyletic species no more – genomic data resolve a Pleistocene radiation and validate morphological species of the Melanoplus scudderi complex (Insecta: Orthoptera)

Jen-Pan Huang, JoVonn G. Hill, Joaquín Ortego & L. Lacey Knowles
Rapid speciation events, with taxa generated over a short time period, are among the most investigated biological phenomena. However, molecular systematics often reveals contradictory results compared with morphological/phenotypical diagnoses of species under scenarios of recent and rapid diversification. In this study, we used molecular data from an average of over 29,000 loci per sample from RADseq to reconstruct the diversification history and delimit the species boundary in a short-winged grasshopper species complex (Melanoplus Scudderi group),...

Conditional female strategies influence hatching success in a communally-nesting iguana

Jeanette B. Moss, Glenn P. Gerber, Tanja Laaser, Matthias Goetz, TayVanis Oyog & Mark E. Welch
The decision of females to nest communally has important consequences for reproductive success. While often associated with reduced energetic expenditure, conspecific aggregations also expose females and offspring to conspecific aggression, exploitation, and infanticide. Intrasexual competition pressures areexpected to favor the evolution of conditional strategies, which could be based on simple decision rules (i.e., availability of nesting sites, synchronicity with conspecifics) or on a focal individual’s condition or status (i.e., body size). Oviparous reptiles that reproduce...

Age-related reproductive performance of the Adélie Penguin, a long-lived seabird exhibiting similar outcomes regardless of individual life-history strategy

Peter Kappes, Katie Dugger, Amélie Lescroël, David Ainley, Grant Ballard, Kerry Barton, Philip Lyver & Peter Wilson
1. Age-related variation in reproductive performance in long-lived iteroparous vertebrate species is common, with performance being influenced by within-individual processes, such as improvement and senescence, in combination with among-individual processes, such as selective appearance and disappearance. Few studies of age-related reproductive performance have compared the role of these drivers within a metapopulation, subject to varying degrees of resource competition. 2. We accounted for within- and among-individuals changes among known-aged Adélie penguins (Pygoscelis adeliae) during 17...

Quantifying niche similarity among new world seed plants--Species Distribution Models (SDMs) & associated metadata

Hector Figueroa, Hannah Marx, CJ Grady, Jim Beach, Ryan Folk, Douglas Soltis, Pamela Soltis, Aimee Stewart & Stephen Smith
Niche shift and conservatism are often framed as mutually exclusive. However, both processes could contribute to biodiversity patterns. We tested this expectation by quantifying the degree of climatic niche similarity among New World seed plants. To incorporate the biological reality that species experience varied abiotic conditions across their range, we assembled distribution models and used these to characterize temperature, precipitation, and elevation niches for species as continuously-valued distributions. We then quantified niche similarity (distributional overlap)...

Population genetic and environmental data for Chamaecrista fasciculata

Lisa Wallace & Mahboubeh Hosseinalizadeh Nobarinezhad
Chamaecrista fasciculata is a widely distributed, phenotypically variable species in the eastern U.S. Whereas studies have demonstrated genetic structure and local adaptation in northern areas of its distribution, there has been no comparison of genetic variability among populations at the southern extent where phenotypic variation is more complex. We characterized genetic variation at 14 microsatellite loci for populations in Mississippi and Alabama and compared this to variation in a phenotypic trait, leaf pubescence. Geographic distance,...

Data from: Attack risk for butterflies changes with eyespot number and size

Sebastian Ho, Sandra R. Schachat, William H. Piel & Antónia Monteiro
Butterfly eyespots are known to function in predator deflection and predator intimidation, but it is still unclear what factors cause eyespots to serve one function over the other. Both functions have been demonstrated in different species that varied in eyespot size, eyespot number and wing size, leaving the contribution of each of these factors to butterfly survival unclear. Here, we study how each of these factors contributes to eyespot function by using paper butterfly models,...

Data from: Combined effects of night warming and light pollution on predator-prey interactions

Colleen R. Miller, Brandon T. Barton, Likai Zhu, Volker C. Radeloff, Kerry M. Oliver, Jason P. Harmon & Anthony R. Ives
Interactions between multiple anthropogenic environmental changes can drive non-additive effects in ecological systems, and the non-additive effects can in turn be amplified or dampened by spatial covariation among environmental changes. We investigated the combined effects of night-time warming and light pollution on pea aphids and two predatory ladybeetle species. As expected, neither night-time warming nor light pollution changed the suppression of aphids by the ladybeetle species that forages effectively in darkness. However, for the more-visual...

Data from: Development and validation of a weather-based warning system to advise fungicide applications to control dollar spot on turfgrass

Damon L. Smith, James P. Kerns, Nathan R. Walker, Andrea F. Payne, Brandon Horvath, John C. Inguagiato, John E. Kaminski, Maria Tomaso-Peterson & Paul L. Koch
Dollar spot is one of the most common diseases of golf course turfgrass and numerous fungicide applications are often required to provide adequate control. Weather-based disease warning systems have been developed to more accurately time fungicide applications; however, they tend to be ineffective and are not currently in widespread use. The primary objective of this research was to develop a new weather-based disease warning system to more accurately advise fungicide applications to control dollar spot...

Data from: Combined morphological and phylogenomic re-examination of malawimonads, a critical taxon for inferring the evolutionary history of eukaryotes.

Aaron A. Heiss, Martin Kolisko, Fleming Ekelund, Matthew W. Brown, Andrew J. Roger, Alastair G.B. Simpson & Alastair G. B. Simpson
Modern syntheses of eukaryote diversity assign almost all taxa to one of three groups: Amorphea, Diaphoretickes, and Excavata (comprising Discoba and Metamonada). The most glaring exception is Malawimonadidae, small heterotrophic flagellates that resemble Excavata by morphology, but group with Amorphea in most phylogenomic analyses. However, just one malawimonad, Malawimonas jakobiformis, has been studied with both morphological and molecular-phylogenetic approaches, raising the spectre of interpretation errors and phylogenetic artefacts from low taxon sampling. We report a...

Data from: Landscape and environmental influences on Mycobacterium ulcerans distribution among aquatic sites in Ghana

Shannon M. Pileggi, Heather Jordan, Julie A. Clennon, Ellen Whitney, M. Eric Benbow, Richard Merritt, Mollie McIntosh, Ryan Kimbirauskas, Pamela Small, Daniel Boayke, Charles Quaye, Jiaguo Qi, Lindsay Campbell, Jenni Gronseth, Edwin Ampadu, William Opare, Lance Waller, Lance A. Waller & Daniel Boakye
Buruli ulcer, caused by Mycobacterium ulcerans, is highly endemic in West Africa. While the mode of transmission is unknown, many studies associate Buruli ulcer with different types of water exposure. We present results from the largest study to date to test for M. ulcerans in aquatic sites and identify environmental attributes associated with its presence. Environmental samples from 98 aquatic sites in the Greater Accra, Ashanti, and Volta regions of Ghana were tested for the...

Data from: First discovery of the charophycean green alga Lychnothamnus barbatus (Charophyceae) extant in the New World

Kenneth G. Karol, Paul M. Skawinski, Richard M. McCourt, Michelle E. Nault, Reesa Evans, Martha E. Barton, Matthew S. Berg, Donna J. Perleberg, John Hall & John D. Hall
Premise of the study: Although some species of Characeae, known as stoneworts, can be found on every continent except Antarctica, many species and some genera have limited geographic distributions. The genus Lychnothamnus, represented by a single extant species L. barbatus, was known only from scattered localities in Europe and Australasia until it was recently discovered in North America. Methods: Morphological identifications were made from specimens collected in Minnesota and Wisconsin, U.S.A. DNA sequences were obtained...

Warmer nights offer no respite for a defensive mutualism

Clesson Higashi, Brandon Barton & Kerry Oliver
1. Ecologically-relevant symbioses are widespread in terrestrial arthropods but based on recent findings these specialized interactions are likely to be especially vulnerable to climate warming. Importantly, empirical data and climate models indicate that warming is occurring asynchronously, with nighttime temperatures increasing faster than daytime temperatures. Daytime (DTW) and nighttime warming (NTW) may impact ectothermic animals and their interactions differently as DTW results in greater daily temperature variation and moves organisms nearer to their thermal limits,...

Comparative analysis of genetic and morphological variation within the Platanthera hyperborea complex (Orchidaceae)

Lisa Wallace, Eranga Wettewa & Nicholas Bailey
Species complexes present considerable problems for a working taxonomy due to the presence of intraspecific variation, hybridization, polyploidy, and phenotypic plasticity. Understanding evolutionary patterns using molecular markers can allow for a more thorough assessment of evolutionary lineages than traditional morphological markers. In this study, we evaluated genetic diversity and phylogenetic patterns among taxa of the Platanthera hyperborea (Orchidaceae) complex, which includes diploid (Platanthera aquilonis) and polyploid (Platanthera hyperborea, P. huronensis, P. convallariifolia) taxa spanning North...

Contrasting patterns of phylogenetic diversity and alpine specialization across the alpine flora of the American mountain range system

Hector Fox Figueroa, Hannah E. Marx, Maria Beatriz De Souza Cortez, Charles J. Grady, Nicholas Engle-Wrye, Jim Beach, Aimee Stewart, Ryan A. Folk, Douglas E. Soltis, Pamela S. Soltis & Stephen A. Smith
Although mountainous habitats contribute substantially to global biodiversity, comparatively little is known about biogeographic patterns of distributions of alpine species across multiple mountain ranges. Here, we present a detailed analysis of the distributions and phylogenetic affinities of alpine seed plant lineages across North, Central, and South American mountain systems. Using a comprehensive dataset that characterized the elevational niches of American seed plants in a continuously valued way, we were able to quantitatively investigate how the...

Low levels of hybridization between domestic and wild Mallards wintering in the Lower Mississippi Flyway

Brian Davis, Diana Outlaw, Kevin Ringelman, Richard Kaminski & Philip Lavretsky
Mallard ducks are a ubiquitous and socio-economically important game bird in North America. Despite their generally abundant midcontinent population, Mallards in eastern North America are declining, which may be partially explained by extensive hybridization with human-released domestically-derived game-farm Mallards. We investigated the genetic composition of Mallards in the middle and lower Mississippi flyway, key wintering regions for the species. We found that nearly 30% of wild Mallards carried mitochondrial haplotypes derived from domestic mallards present...

Satellite telemetry data of Double-crested cormorant locations

Guiming Wang, D. Tommy King & Fred Cunningham
Avian migrants are challenged by seasonal adverse climatic conditions and energetic costs of long-distance flying. Migratory birds may track or switch seasonal climatic niche between the breeding and non-breeding grounds. Satellite tracking enables avian ecologists to investigate seasonal climatic niche and circannual movement patterns of migratory birds. The Double-crested Cormorant (Nannopterum auritum, hereafter cormorant) wintering in the Gulf of Mexico (GOM) migrate to the Northern Great Plains and Great Lakes and is of economic importance...
