Data from: History, geography, and host use shape genome-wide patterns of genetic variation in the redheaded pine sawfly (Neodiprion lecontei)Robin K. Bagley, Vitor C. Sousa, Matthew L. Niemiller & Catherine R. Linnen
Divergent host use has long been suspected to drive population differentiation and speciation in plant-feeding insects. Evaluating the contribution of divergent host use to genetic differentiation can be difficult, however, as dispersal limitation and population structure may also influence patterns of genetic variation. In this study, we use double-digest restriction-associated DNA (ddRAD) sequencing to test the hypothesis that divergent host use contributes to genetic differentiation among populations of the redheaded pine sawfly (Neodiprion lecontei), a...
Data from: Genomic data detect corresponding signatures of population size change on an ecological time scale in two salamander speciesSchyler O. Nunziata, Stacey L. Lance, David E. Scott, Emily M. Lemmon, David W. Weisrock & Emily Moriarty Lemmon
Understanding the demography of species over recent history (e.g., < 100 years) is critical in studies of ecology and evolution, but records of population history are rarely available. Surveying genetic variation is a potential alternative to census-based estimates of population size, and can yield insight into the demography of a population. However, to assess the performance of genetic methods it is important to compare their estimates of population history to known demography. Here, we leveraged...
Data from: Author-suggested reviewers: gender differences and influences on the peer review process at an ecology journalCharles W. Fox, C. Sean Burns, Anna D. Muncy & Jennifer A. Meyer
Peer review is the primary method by which journals evaluate the quality and importance of scientific papers. To help editors find suitable reviewers, many journals allow or require authors to suggest names of preferred and nonpreferred reviewers. Though authors should know best who is qualified to review their papers, they also have a strong incentive to suggest reviewers that they expect to review their paper positively. In this study, we examine the reviewers that are...
Data from: Species discovery and validation in a cryptic radiation of endangered primates: coalescent-based species delimitation in Madagascar's mouse lemursScott Hotaling, Mary Foley, Nicolette Lawrence, Jose Bocanegra, Marina B. Blanco, Rodin Rasoloarison, Peter M. Kappeler, Meredith A. Barrett, Anne D. Yoder, David W. Weisrock, Mary E. Foley & Nicolette M. Lawrence
Implementation of the coalescent model in a Bayesian framework is an emerging strength in genetically based species delimitation studies. By providing an objective measure of species diagnosis, these methods represent a quantitative enhancement to the analysis of multilocus data, and complement more traditional methods based on phenotypic and ecological characteristics. Recognized as two species 20 years ago, mouse lemurs (genus Microcebus) now comprise more than 20 species, largely diagnosed from mtDNA sequence data. With each...
Data from: Foraging modality and plasticity in foraging traits determine the strength of competitive interactions among carnivorous plants, spiders, and toadsDavid E. Jennings, James J. Krupa & Jason R. Rohr
1. Foraging modalities (e.g., passive, sit-and-wait, active) and traits are plastic in some species, but the extent to which this plasticity affects interspecific competition remains unclear. 2. Using a long-term laboratory mesocosm experiment, we quantified competition strength and the plasticity of foraging traits in a guild of generalist predators of arthropods with a range of foraging modalities. 3. Each mesocosm contained eight passively foraging pink sundews, and we employed an experimental design where treatments were...
Data from: Differential aphid toxicity to ladybeetles is not a function of host plant or facultative bacterial symbiontsJennifer A. White, Joshua S. McCord, Kelly A. Jackson, Allison C. Dehnel & Paul A. Lenhart
Herbivores often defend themselves from predation by transmitting toxic plant-produced chemicals to their enemies. Polyphagous herbivores sometimes exhibit differential toxicity when found on various host plant species, which is generally assumed to reflect variation in plant chemistry. Here, however, we provide evidence that host-associated herbivore lineages can intrinsically differ in their toxic properties. Lineages of Aphis craccivora originating from black locust (Robinia pseudoacacia) are unsuitable food for the ladybeetle Harmonia axyridis, resulting in death of...
Data from: Mechanical conflict system: a novel operant method for the assessment of nociceptive behaviorSteven Harte, Jessica B. Meyers, Renee Donahue, Bradley K. Taylor, Thomas J. Morrow, Steven E. Harte & Renee R. Donahue
A new operant test for preclinical pain research, termed the Mechanical Conflict System (MCS), is presented. Rats were given a choice either to remain in a brightly lit compartment or to escape to a dark compartment by crossing an array of height-adjustable nociceptive probes. Latency to escape the light compartment was evaluated with varying probe heights (0, .5, 1, 2, 3, and 4 mm above compartment floor) in rats with neuropathic pain induced by constriction...
Trophic complexity in aqueous systems: bacterial species richness and protistan predation regulate dissolved organic carbon and dissolved total nitrogen removalMuhammad Saleem, Ingo Fetzer, Hauke Harms & Antonis Chatzinotas
Loading of water bodies with dissolved organic carbon (DOC) and dissolved total nitrogen (DTN) affects their integrity and functioning. Microbial interactions mitigate the negative effects of high nutrient loads in these ecosystems. Despite numerous studies on how biodiversity mediates ecosystem functions, whether and how diversity and complexity of microbial food webs (horizontal, vertical) and the underlying ecological mechanisms influence nutrient removal has barely been investigated. Using microbial microcosms accommodating systematic combinations of prey (bacteria) and...
Data from: Two complete mitochondrial genomes from Praticolella mexicana Perez, 2011 (Polygyridae) and gene order evolution in Helicoidea (Mollusca, Gastropoda)Russell L. Minton, Marco A. Martinez Cruz, Mark L. Farman & Kathryn E. Perez
Helicoidea is a diverse group of globally distributed land snails. While much is known regardingthe relationships of helicoid taxa, comparatively little is known about the evolution of themitochondrial genome in the superfamily. We sequenced two complete mitochondrial genomesfrom Praticolella mexicana Perez, 2011 representing the first such data from the helicoid familyPolygyridae, and used them in an evolutionary analysis of mitogenomic gene order. We foundthe mitochondrial genome of P. mexicana to be 14,008 bp in size,...
A central goal of evolutionary biology is to understand the molecular mechanisms underlying phenotypic adaptation. While the contribution of protein-coding and cis-regulatory mutations to adaptive traits has been well documented, additional sources of variation – such as the production of alternative RNA transcripts from a single gene, or isoforms – have been understudied. Here, we focus on the pigmentation gene Agouti, known to express multiple alternative transcripts, to investigate the role of isoform usage in...
Data from: Sources of (co)variation in alternative siring routes available to male great tits (Parus major)Yimen G. Araya-Ajoy, Sylvia Kuhn, Kimberley J. Mathot, Alexia Mouchet, Ariane Mutzel, Marion Nicolaus, Jan J. Wijmenga, Bart Kempenaers & Niels J. Dingemanse
Males of socially monogamous species can increase their siring success via within-pair and extra-pair fertilizations. In this study, we focused on the different sources of (co)variation between these siring routes, and asked how each contributes to total siring success. We quantified the fertilization routes to siring success, as well as behaviors that have been hypothesized to affect siring success, over a five-year period for a wild population of great tits Parus major. We considered siring...
Data from: The influence of locus number and information content on species delimitation: an empirical test case in an endangered Mexican salamanderPaul M. Hime, Scott Hotaling, Richard E. Grewelle, Eric M. O'Neill, S. Randal Voss, H. Bradley Shaffer & David W. Weisrock
Perhaps the most important recent advance in species delimitation has been the development of model-based approaches to objectively diagnose species diversity from genetic data. Additionally, the growing accessibility of next-generation sequence datasets provides powerful insights into genome-wide patterns of divergence during speciation. However, applying complex models to large datasets is time consuming and computationally costly, requiring careful consideration of the influence of both individual and population sampling, as well as the number and informativeness of...
Data from: Effects of roads and land use on frog distributions across spatial scales and regions in the eastern and central United StatesDavid M. Marsh, Bradley J. Cosentino, Kara S. Jones, Joseph J. Apodaca, Karen H. Beard, Jane M. Bell, Christine Bozarth, Derrick Carper, Julie F. Charbonnier, Andreia Dantas, Elizabeth Forys, Miran Foster, Jaquelyn General, Kristen S. Genet, Macie Hanneken, Kyle R. Hess, Shane A. Hill, Faisal Iqbal, Nancy E. Karraker, Eran S. Kilpatrick, Tom A. Langen, James Langford, Kathryn Lauer, Alison J. McCarthy, Joseph Neale … & Mohammad Tasleem
Aim: Understanding the scales over which land use affects animal populations is critical for conservation planning, and it can provide information about the mechanisms that underlie correlations between species distributions and land use. We used a citizen-science database of anuran surveys to examine the relationship between road density, land use, and the distribution of frogs and toads across spatial scales and regions of the United States. Location: Eastern and Central United States Methods: We compiled...
Data from: Multigenerational exposure to silver ions and silver nanoparticles reveals heightened sensitivity and epigenetic memory in Caenorhabditis elegansCarolin L. Schultz, Anye Wamucho, Olga V. Tsyusko, Jason M. Unrine, Alison Crossley, Claus Svendsen & David J. Spurgeon
The effects from multigenerational exposures to engineered nanoparticles (ENPs) in their pristine and transformed states are currently unknown despite such exposures being an increasingly common scenario in natural environments. Here, we examine how exposure over 10 generations affects the sensitivity of the nematode Caenorhabditis elegans to pristine and sulfidized Ag ENPs and AgNO3. We also include populations that were initially exposed over six generations but kept unexposed for subsequent four generations to allow recovery from...
Data from: Surprising flexibility in parental care revealed by experimental changes in offspring demandKatherine Pelletier, Chelsey Oedewaldt & David F. Westneat
Parental behaviour often exhibits plasticity to factors expected to affect the benefits or costs of care. For example, parent songbirds typically increase their provisioning behaviour as nestlings mature. Several mechanisms exist that could allow parents to track nestling age and provide appropriate care. We performed a short-term experiment on house sparrows, Passer domesticus, in which offspring of different ages were exchanged to assess the level of flexibility parents exhibit and the likely cues they use....
