Environmental variation favors the evolution of phenotypic plasticity. For many species, we understand the costs and benefits of different phenotypes, but we lack a broad understanding of how plastic traits evolve across large clades. Using identical experiments conducted across North America, we examined prey responses to predator cues. We quantified five life history traits and the magnitude of their plasticity for 23 amphibian species/populations (spanning three families and five genera) when exposed to no cues,...

Data from: Associations between blooming plants and their bee visitors in a riparian ecosystem in eastern Oregon

Samantha M. Roof, Sandra J. DeBano, Mary M. Rowland, Skyler Burrows & Sandra DeBano
Native bees are declining world-wide, but conserving or restoring their habitat requires a better understanding of bee-flower associations. High quality bee habitat includes flowers that provide pollen and nectar preferred by bees. However, little data exist about which plants are commonly used by bees in the Pacific Northwest, or whether bees prefer certain plant characteristics over others. We examined bee and plant communities in an Oregon riparian ecosystem. Our purpose was to describe bee-plant associations,...

Data from: Molecular signatures of host specificity linked to habitat specialization in Exaiptasia sea anemones.

Emily S. Bellis, Reid B. Edlund, Hazel K. Berrios, Harilaos A. Lessios, Dee R. Denver & Reid. B. Edlund
Rising ocean temperatures associated with global climate change induce breakdown of the symbiosis between coelenterates and photosynthetic microalgae of the genus Symbiodinium. Association with more thermotolerant partners could contribute to resilience, but the genetic mechanisms controlling specificity of hosts for particular Symbiodinium types are poorly known. Here we characterize wild populations of a sea anemone laboratory model system for anthozoan symbiosis, from contrasting environments in Caribbean Panama. Patterns of anemone abundance and symbiont diversity were...

Data from: Tick-borne disease risk in a forest food web

Richard S. Ostfeld, Taal Levi, Felicia Keesing, Kelly Oggenfuss & Charles D. Canham
Changes to the community ecology of hosts for zoonotic pathogens, particularly rodents, are likely to influence the emergence and prevalence of zoonotic diseases worldwide. However, the complex interactions between abiotic factors, pathogens, vectors, hosts, and both food resources and predators of hosts are difficult to disentangle. Here we (1) use 19 years of data from six large field plots in southeastern New York to compare the effects of hypothesized drivers of interannual variation in Lyme...

Data from: Association of orthostatic hypotension with incident dementia, stroke, and cognitive decline

Andreea M. Rawlings, Stephen P. Juraschek, Gerardo Heiss, Tim Hughes, Michelle L. Meyer, Elizabeth Selvin, A. Richey Sharrett, B. Gwen Windham & Rebecca F. Gottesman
Objective: To examine associations between orthostatic hypotension (OH) with dementia and long-term cognitive decline, and update previously published results in the same cohort for stroke with an additional 16 years of follow-up. Methods: We analyzed data from 11709 participants without a history of coronary heart disease or stroke who attended the baseline exam (1987-1989) of the prospective Atherosclerosis Risk in Communities (ARIC) study. OH was defined as a drop in systolic blood pressure (BP) of...

Data from: Phylogenetic relationships and convergent evolution of ocean-shore ground beetles (Coleoptera: Carabidae: Trechinae: Bembidion and relatives)

David R. Maddison & Munetoshi Maruyama
Through phylogenetic analysis of seven genes, we show that there have been at least six independent entries into intertidal habitats in the history of bembidiine carabids, in the ancestors of: (i) Orzolina Machado, (ii) Bembidion (Desarmatocillenus Netolitzky), (iii) Bembidion laticeps (LeConte) + palosverdes Kavanaugh & Erwin, (iv) Bembidion laterale (Samouelle), (v) Bembidion umi Sasakawa and Bembidion quadriimpressum (Motschulsky) (which may represent two separate entries), and (vi) B. nigropiceum (Marsham). The following lineages are widely separated...

Data from: Human activity reduces niche partitioning among three widespread mesocarnivores

Justine A. Smith, Austen C. Thomas, Taal Levi, Yiwei Wang & Christopher C. Wilmers
Anthropogenic disturbances can constrain the realized niche space of wildlife by inducing avoidance behaviors and altering community dynamics. Human activity might contribute to reduced partitioning of niche space by carnivores that consume similar resources, both by promoting tolerant species while also altering behavior of species (e.g. activity patterns). We investigated the influence of anthropogenic disturbance on habitat and dietary niche breadth and overlap among competing carnivores, and explored if altered resource partitioning could be explained...

Data from: Experimental brood enlargement differentially influences the magnitude of the corticosterone stress response in closely related, co‐occurring songbirds

Braelei M. Hardt, Daniel R. Ardia, Meredith J. Bashaw & James W. Rivers
1. Rearing environments can shape offspring phenotype across taxa, yet little is known about how brood size influences hypothalamic-pituitary axis functioning, whether its expression trades off with growth, and the degree to which these relationships vary between species. 2. We evaluated how brood size influenced nestling physiological (glucocorticoids) and somatic traits (growth), and the extent to which these relationships differed between two closely related, sympatric songbirds when experiencing identical rearing environments. Specifically, we used a...

Data from: Phenological responses of 215 moth species to interannual climate variation in the Pacific Northwest from 1895 through 2013

Julie A. Maurer, Jon H. Shepard, Lars G. Crabo, Paul C. Hammond, Richard S. Zack & Merrill A. Peterson
Climate change has caused shifts in the phenology and distributions of many species but comparing responses across species is challenged by inconsistencies in the methodology and taxonomic and temporal scope of individual studies. Natural history collections offer a rich source of data for examining phenological shifts for a large number of species. We paired specimen records from Pacific Northwest insect collections to climate data to analyze the responses of 215 moth species to interannual climate...

Data from: Seasonal dynamics of spatial distribution and overlap between Northeast Arctic cod (Gadus morhua) and capelin (Mallotus villosus) in the Barents Sea

Johanna Fall, Lorenzo Ciannelli, Georg Skaret & Edda Johannesen
The trophic link between cod (Gadus sp.) and capelin (Mallotus sp.) is important in many panarctic ecosystems. Since the early 2000s, the Northeast Arctic cod stock (G. morhua) in the Barents Sea has increased greatly, and the sea has been exceptionally warm. Such changes have potentially large effects on species distributions and overlap, which in turn could affect the strength of species interactions. Due to its high latitude location, the Barents Sea has strong seasonal...

Data from: The dynamics of open populations: integration of top–down, bottom–up and supply‐side influences on intertidal oysters

David L. Kimbro, James Wilson White & Edwin D. Grosholz
Most communities are structured not by a single process but by some combination of top–down, bottom–up and supply‐side (i.e. juvenile recruitment) factors. However, establishing how multiple processes interact remains a fundamental challenge. For example, the recruitment, growth, and mortality of estuarine species can vary along the steep and numerous environmental and biological gradients typical of these habitats, but the relative importance of those gradients is generally unknown. We took a novel approach to this question...

Data from: Non-stationary climate-salmon relationships in the Gulf of Alaska

Michael A. Litzow, Lorenzo Ciannelli, Patricia Puerta, Justin J. Wettstein, Ryan R. Rykaczewski & Michael Opiekun
Studies of climate effects on ecology often account for non-stationarity in individual physical and biological variables, but rarely allow for non-stationary relationships among variables. Here, we show that non-stationary relationships among physical and biological variables are central to understanding climate effects on salmon (Onchorynchus spp.) in the Gulf of Alaska during 1965-2012. The relative importance of two leading patterns in North Pacific climate, the Pacific Decadal Oscillation (PDO) and North Pacific Gyre Oscillation (NPGO), changed...

Data from: Quantifying the digestive fingerprints of predators on the bones of their prey using scanning electron microscopy

Rebecca C. Terry, Jesse A. Laney & Samuel H. Hay-Roe
Paleoecological reconstruction relies on accurately determining the taphonomic origin of fossil deposits. Predation is a common mechanism by which skeletal remains become concentrated over time, leading to the formation of modern and fossil prey death assemblages. Skeletal element representation and breakage patterns within such death assemblages can be used to infer the identity of the responsible predator. However, assemblage-level metrics cannot be used to infer if a single fossil specimen is predator-derived. Microscopic digestive etching...

Data from: Towards a predictive model of species interaction beta diversity

Catherine H. Graham, Benjamin G. Weinstein & Ben G. Weinstein
Species interactions are fundamental to community dynamics and ecosystem processes. Despite significant progress in describing species interactions, we lack the ability to predict changes in interactions across space and time. We outline a Bayesian approach to separate the probability of species co‐occurrence, interaction and detectability in influencing interaction betadiversity. We use a multi‐year hummingbird–plant time series, divided into training and testing data, to show that including models of detectability and occurrence improves forecasts of mutualistic...

Ocean acidification stress index for shellfish (OASIS): Linking Pacific oyster larval survival and exposure to variable carbonate chemistry regimes

Iria Gimenez Calvo, George Waldbusser & Burke Hales
Understanding larval bivalve responses to variable regimes of seawater carbonate chemistry requires realistic quantification of physiological stress. Based on a degree-day modeling approach, we developed a new metric, the ocean acidification stress index for shellfish (OASIS), for this purpose. OASIS integrates over the entire larval period the instantaneous stress associated with deviations from published sensitivity thresholds to aragonite saturation state (ΩAr) while experiencing variable carbonate chemistry. We measured survival to D-hinge and pre-settlement stage of...

Data from: Within-species patterns challenge our understanding of the Leaf Economics Spectrum

Leander D.L. Anderegg, Logan T. Berner, Grayson Badgley, Meera L. Sethi, Beverly E. Law, Janneke HilleRisLambers & Leander D. L. Anderegg
The utility of plant functional traits for predictive ecology relies on our ability to interpret trait variation across multiple taxonomic and ecological scales. Using extensive datasets of trait variation within species, across species, and across communities, we analyzed whether and at what scales ‘leaf economics spectrum’ (LES) traits show predicted trait-trait covariation. We found that most variation in LES traits is often, but not universally, at high taxonomic levels (between families, between genera in a...

Data from: Assessing changes in functional connectivity in a desert bighorn sheep metapopulation after two generations

Clinton W. Epps, Rachel S. Crowhurst & Brandon S. Nickerson
Determining how species move across complex and fragmented landscapes and interact with human-made barriers is a major research focus in conservation. Studies estimating functional connectivity from movement, dispersal, or gene flow usually rely on a single study period, and rarely consider variation over time. We contrasted genetic structure and gene flow across barriers for a metapopulation of desert bighorn sheep (Ovis canadensis nelsoni) using genotypes collected 2000–2003 and 2013–2015. Based on the recently observed but...

Data from: Herbivory and eutrophication mediate grassland plant nutrient responses across a global climatic gradient

T. Michael Anderson, Daniel M. Griffith, James B. Grace, Eric M. Lind, Peter B. Adler, Lori A. Biederman, Dana M. Blumenthal, Pedro Daleo, Jennifer Firn, Nicole Hagenah, W. Stanley Harpole, Andrew S. MacDougall, Rebecca L. McCulley, Suzanne M. Prober, Anita C. Risch, Mahesh Sankaran, Martin Schütz, Eric W. Seabloom, Carly J. Stevens, Lauren L. Sullivan, Peter D. Wragg & Elizabeth T. Borer
Plant stoichiometry, the relative concentration of elements, is a key regulator of ecosystem functioning and is also being altered by human activities. In this paper we sought to understand the global drivers of plant stoichiometry and compare the relative contribution of climatic vs. anthropogenic effects. We addressed this goal by measuring plant elemental (C, N, P and K) responses to eutrophication and vertebrate herbivore exclusion at eighteen sites on six continents. Across sites, climate and...

Data from: Phylogenomic analyses reveal a deep history of hybridization and polyploidy in the Neotropical genus Lachemilla (Rosaceae)

Diego F. Morales-Briones, Aaron Liston & David C. Tank
Hybridization, incomplete lineage sorting, and phylogenetic error produce similar incongruence patterns, representing a great challenge for phylogenetic reconstruction. Here, we use sequence capture data and multiple species tree and species network approaches to resolve the backbone phylogeny of the Neotropical genus Lachemilla, while distinguishing among sources of incongruence. We used 396 nuclear loci and nearly complete plastome sequences from 27 species to clarify the relationships among the major groups of Lachemilla, and explored multiple sources...

Data from: Severe fire weather and intensive forest management increase fire severity in a multi-ownership landscape

Harold S.J. Zald, Christopher J. Dunn & Harold S. J. Zald
Many studies have examined how fuels, topography, climate, and fire weather influence fire severity. Less is known about how different forest management practices influence fire severity in multi-owner landscapes, despite costly and controversial suppression of wildfires that do not acknowledge ownership boundaries. In 2013, the Douglas Complex burned over 19,000 ha of Oregon & California Railroad (O&C) lands in Southwestern Oregon, USA. O&C lands are comprised of a checkerboard of private industrial and federal forestland...

Data from: Herbicides and herbivory interact to drive plant community and crop-tree establishment

Thomas D. Stokely, Jake Verschuyl, Joan C. Hagar & Matthew G. Betts
Land management practices often directly alter vegetation structure and composition, but the degree to which ecological processes such as herbivory interact with management to influence biodiversity is less well understood. We hypothesized that large herbivores compound the effects of intensive forest management on early-seral plant communities and plantation establishment (i.e., tree survival and growth), and the degree of such effects is dependent on the intensity of management practices. We established 225 m2 wild ungulate (deer...

Data from: Context-dependent costs and benefits of tuberculosis resistance traits in a wild mammalian host

Hannah F. Tavalire, Brianna R. Beechler, Peter E. Buss, Erin E. Gorsich, Eileen G. Hoal, Nikki Le Roex, Johannie M. Spaan, Robert S. Spaan, Paul D. Van Helden, Vanessa O. Ezenwa & Anna E. Jolles
Disease acts as a powerful driver of evolution in natural host populations, yet individuals in a population often vary in their susceptibility to infection. Energetic trade-offs between immune and reproductive investment lead to the evolution of distinct life-history strategies, driven by the relative fitness costs and benefits of resisting infection. However, examples quantifying the cost of resistance outside of the laboratory are rare. Here, we observe two distinct forms of resistance to bovine tuberculosis (bTB),...

Data from: Weed control with Bicyclopyrone + Bromoxynil in wheat

Carolina San Martín, Drew J. Lyon, Jennifer Gourlie, Henry C. Wetzel & Judit Barroso
Chemical weed control options in wheat (Triticum aestivum L.) cropping systems of the Pacific Northwest (PNW) are currently limited due to the presence of resistant weed biotypes. The efficacy of a new post-emergence herbicide in wheat, bicyclopyrone + bromoxynil (Talinor®), was evaluated for mayweed chamomile (Anthemis cotula L.) and prickly lettuce (Lactuca serriola L.) control in eastern Washington and Oregon in 2016 and 2017. Bicyclopyrone + bromoxynil provided superior control of mayweed chamomile in winter...

Data from: Systematic revision of Symbiodiniaceae highlights the antiquity and diversity of coral endosymbionts

Todd C. LaJeunesse, John Everett Parkinson, Paul W. Gabrielson, Hae Jin Jeong, James Davis Reimer, Christian R. Voolstra & Scott R. Santos
The advent of molecular data has transformed the science of organizing and studying life on Earth. Genetics-based evidence provides fundamental insights into the diversity, ecology, and origins of many biological systems, including the mutualisms between metazoan hosts and their micro-algal partners. A well-known example is the dinoflagellate endosymbionts (“zooxanthellae”) that power the growth of stony corals and coral reef ecosystems. Once assumed to encompass a single panmictic species, genetic evidence has revealed a divergent and...
