Data from: Can avian functional traits predict cultural ecosystem services?

Alejandra Echeverri, Daniel Karp, Robin Naidoo, Joseph Tobias, Jiaying Zhao & Kai Chan
The functional trait diversity of species assemblages can predict the provision of ecosystem services such as pollination and carbon sequestration, but it is unclear whether the same trait-based framework can be applied to identify the factors that underpin cultural ecosystem services and disservices. To explore the relationship between traits and the contribution of species to cultural ecosystem services and disservices, we conducted 404 questionnaire surveys with birdwatchers and local residents in Guanacaste, Costa Rica. We...

Data from: Climatic change only stimulated growth for trees under weak competition in central boreal forests

Yong Luo, Eliot J. B. McIntire, Celine Boivenue, Paul P. Nikiema & Han H. Y. Chen
1. Global change ecologists have often used trees under weak competition (e.g., dominant/codominant trees) to examine relationships between climatic change and tree growth. Scaling up these results to a forest relies on the assumption that the climatic change-tree growth relationship is not affected by tree-level competition. 2. Using permanent sample plot data from the central Canadian boreal region where warming did not result in water deficit, we tested the above-mentioned assumption by looking at whether...

Species differences in phenology shape coexistence

Christopher Blackford, Rachel Germain & Benjamin Gilbert
Ecological theory produces opposing predictions about whether differences in the timing of life history transitions, or ‘phenology’, promote or limit coexistence. Phenological separation is predicted to create temporal niche differences, increasing coexistence, yet phenological separation could also competitively favour one species, increasing fitness differences and hindering coexistence. We experimentally manipulated relative germination timing, a critical phenological event, of two annual grass species, Vulpia microstachys and V. octoflora, to test these contrasting predictions. We parameterized a...

Data from: Testing predictions of inclusive fitness theory in inbreeding relatives with biparental care

Elizabeth Gow, Peter Arcese, Danielle Dagenais, Rebecca Sardell, Scott Wilson & Jane Reid
Inclusive fitness theory predicts that parental care will vary with relatedness between potentially caring parents and offspring, potentially shaping mating system evolution. Systems with extra-pair paternity (EPP), and hence variable parent-brood relatedness, provide valuable opportunities to test this prediction. However, existing theoretical and empirical studies assume that a focal male is either an offspring’s father with no inbreeding, or is completely unrelated. We highlight that this simple dichotomy does not hold given reproductive interactions among...

Data from: Climate impacts on the ocean are making the Sustainable Development Goals a moving target traveling away from us

Gerald G. Singh, Nathalie Hilmi, Joey R. Bernhardt, Andres M. Cisneros Montemayor, Madeline Cashion, Yoshitaka Ota, Sevil Acar, Jason M. Brown, Richard Cottrell, Salpie Djoundourian, Pedro C. Gonzalez-Espinosa, Vicky Lam, Nadine Marshall, Barbara Neumann, Nicolas Pascal, Gabriel Reygondeau, Joacim Rocklov, Alain Safa, Laura R. Virto & William Cheung
1. Climate change is impacting marine ecosystems and their goods and services in diverse ways, which can directly hinder our ability to achieve the Sustainable Development Goals, set out under the 2030 Agenda for Sustainable Development. 2. Through expert elicitation and a literature review, we find that most climate change effects have a wide variety of negative consequences across marine ecosystem services, though most studies have highlighted impacts from warming and consequences to marine species....

Data from: Species richness change across spatial scales

Jonathan M. Chase, Brian J. McGill, Patrick L. Thompson, Laura H. Antão, Amanda E. Bates, Shane A. Blowes, Maria Dornelas, Andrew Gonzalez, Anne E. Magurran, Sarah R. Supp, Marten Winter, Anne D. Bjorkmann, Helge Bruelheide, Jarrett E.K. Byrnes, Juliano Sarmento Cabral, Robin Ehali, Catalina Gomez, Hector M. Guzman, Forest Isbell, Isla H. Myers-Smith, Holly P. Jones, Jessica Hines, Mark Vellend, Conor Waldock & Mary O'Connor
Humans have elevated global extinction rates and thus lowered global-scale species richness. However, there is no a priori reason to expect that losses of global species richness should always, or even often, trickle down to losses of species richness at regional and local scales, even though this relationship is often assumed. Here, we show that scale can modulate our estimates of species richness change through time in the face of anthropogenic pressures, but not in...

Data from: A metadata approach to evaluate the state of ocean knowledge: strengths, limitations, and application to Mexico

Juliano Palacios-Abrantes, Andrés M. Cisneros-Montemayor, Miguel A. Cisneros-Mata, Laura Rodríguez, Francisco Arreguín-Sánchez, Veronica Aguilar, Santiago Domínguez-Sánchez, Stuart Fulton, Raquel López-Sagástegui, Hector Reyes-Bonilla, Rocio Rivera-Campos, Silvia Salas, Nuno Simoes & William W. L. Cheung
Climate change, mismanaged resource extraction, and pollution are reshaping global marine ecosystems with direct consequences on human societies. Sustainable ocean development requires knowledge and data across disciplines, scales and knowledge types. Although several disciplines are generating large amounts of data on marine socio-ecological systems, such information is often underutilized due to fragmentation across institutions or stakeholders, limited standardization across scale, time or disciplines, and the fact that information is often not searchable within existing databases....

Data from: Extensive reduction of the nuclear pore complex in nucleomorphs

Nicholas A. T. Irwin & Patrick J. Keeling
The nuclear pore complex (NPC) is a large macromolecular assembly situated within the pores of the nuclear envelope. Through interactions between its subcomplexes and import proteins, the NPC mediates the transport of molecules into and out of the nucleus and facilitates dynamic chromatin regulation and gene expression. Accordingly, the NPC constitutes a highly integrated nuclear component that is ubiquitous and conserved amongst eukaryotes. Potential exceptions to this are nucleomorphs: highly reduced, relict nuclei that were...

Data from: A new way to estimate neurologic disease prevalence in the United States

Lorene M. Nelson, Mitchell T. Wallin, Ruth Ann Marrie, W.J. Culpepper, Annette Langer-Gould, Jon Campbell, Stephen Buka, Helen Tremlett, Gary Cutter, Wendy Kaye, Laurie Wagner & Nicholas G. Larocca
Objective: Considerable gaps exist in knowledge regarding the prevalence of neurologic diseases, such as multiple sclerosis (MS), in the United States. Therefore, the MS Prevalence Working Group sought to review and evaluate alternative methods for obtaining a scientifically valid estimate of national MS prevalence in the current health care era. Methods: We carried out a strengths, weaknesses, opportunities, and threats (SWOT) analysis for 3 approaches to estimate MS prevalence: population-based MS registries, national probability health...

Data from: Ionome and elemental transport kinetics shaped by parallel evolution in threespine stickleback

Seth M. Rudman, Jared M. Goos, Joseph B. Burant, Kevin V. Brix, Taylor C. Gibbons, Colin J. Brauner & Punidan D. Jeyasingh
Evidence that organisms evolve rapidly enough to alter ecological dynamics necessitates investigation of the reciprocal links between ecology and evolution. Data that link genotype to phenotype to ecology are needed to understand both the process and ecological consequences of rapid evolution. Here we quantified the suite of elements in individuals (i.e., ionome) and the fluxes of key nutrients across populations of threespine stickleback. We find that allelic variation associated with freshwater adaptation that controls bony...

Data from: Defining isoscapes in the Northeast Pacific as an index of ocean productivity

Boris Espinasse
Aim: We modeled isoscapes in the Northeast Pacific using satellite-based data with the main objective of testing if isoscapes defined by a few key parameters can be used as a proxy for secondary productivity. Location: Northeast (NE) Pacific; 46 – 60⁰N and 125 – 165⁰W. Time period: From 1998 to 2017 (ongoing). Major taxa studied: Zooplankton with a focus on large herbivores. Methods: Approximately 280 summer zooplankton samples were analyzed for Carbon (δ13C) and Nitrogen...

Data from: Resistance of soil biota and plant growth to disturbance increases with plant diversity

Jonathan Bennett, Alexander Koch, Jennifer Forsythe, Nancy Johnson, David Tilman & John Klironomos
Plant diversity is critical to the functioning of ecosystems, potentially mediated in part by interactions with soil biota. Here, we characterized multiple groups of soil biota across a plant diversity gradient in a long-term experiment. We then subjected soil samples taken along this gradient to drought, freezing, and a mechanical disturbance to test how plant diversity affects the responses of soil biota and growth of a focal plant to these disturbances. High plant diversity resulted...

Not a melting pot: plant species aggregate in their non-native range

Gisela C. Stotz, James F. Cahill, Jonathan A. Bennett, Cameron N. Carlyle, Edward W. Bork, Diana Askarizadeh, Sandor Bartha, Carl Beierkuhnlein, Bazartseren Boldgiv, Leslie Brown, Marcelo Cabido, Giandiego Campetella, Stefano Chelli, Ofer Cohen, Sandra Díaz, Lucas Enrico, David Ensing, Batdelger Erdenetsetseg, Alessandra Fidelis, Heath W. Garris, Hugh A.L. Henry, Anke Jentsch, Mohammad Hassan Jouri, Kadri Koorem, Peter Manning … & Lauchlan H. Fraser
Aim: Plant species continue to be moved outside of their native range by human activities. Here, we aim at determining whether, once introduced, plants assimilate into native communities, or whether they aggregate, thus forming mosaics of native- and alien-rich communities. Alien species may aggregate in their non-native range due to shared habitat preferences, such as their tendency to establish in high-biomass, species-poor areas. Location: 22 herbaceous grasslands in 14 countries, mainly in the temperate zone....

Data from: Conserving evolutionary history does not result in greater diversity over geological timescales

Juan Cantalapiedra, Tracy Aze, Marc Cadotte, Giulio Valentino Dalla Riva, Danwei Huang, Florent Mazel, Matthew Pennell, María Ríos & Arne Mooers
Alternative prioritization strategies have been proposed to safeguard biodiversity over macro-evolutionary timescales. The first prioritizes the most distantly related species (maximizing phylogenetic diversity) in the hopes of capturing at least some lineages that will successfully diversify into the future. The second prioritizes lineages that are currently speciating, in the hopes that successful lineages will continue to generate species into the future. These contrasting schemes also map onto contrasting predictions about the role of slow diversifiers...

Data from: Mitotic recombination and rapid genome evolution in the invasive forest pathogen Phytophthora ramorumm

Angela L. Dale, Nicolas Feau, Sydney E. Everhart, Braham Dhillon, Barbara Wong, Julie Sheppard, Guillaume J. Bilodeau, Avneet Brar, Javier F. Tabima, Danyu Shen, Clive M. Brasier, Brett M. Tyler, Niklaus J. Grünwald & Richard C. Hamelin
Invasive alien species often have reduced genetic diversity and must adapt to new environments. Given the success of many invasions, this is sometimes called the genetic paradox of invasion. Phytophthora ramorum is invasive, limited to asexual reproduction within four lineages, and presumed clonal. NA1 is responsible for sudden oak death in the USA, NA1, NA2 and EU1 are responsible for ramorum blight in the USA and Canada and EU1 and EU2 are responsible for sudden...

Data from: Evidence for contemporary and historical gene flow between guppy populations in different watersheds, with a test for associations with adaptive traits

Léa Blondel, Lyndsey Baillie, Jessica Quinton, Jahson B. Alemu, Ian Paterson, Andrew P. Hendry & Paul Bentzen
In dendritic river systems, gene flow is expected to occur primarily within watersheds. Yet, rare cross‐watershed transfers can also occur, whether mediated by (often historical) geological events or (often contemporary) human activities. We explored these events and their potential evolutionary consequences by analyzing patterns of neutral genetic variation (microsatellites) and adaptive phenotypic variation (male color) in wild guppies (Poecilia reticulata) distributed across two watersheds in northern Trinidad. We found the expected signatures of within‐watershed gene...

Data from: EFHC1, implicated in juvenile myoclonic epilepsy, functions at the cilium and synapse to modulate dopamine signaling

Catrina M. Loucks, Kwangjin Park, Denise S. Walker, Andrea H. McEwan, Tiffany A. Timbers, Evan L. Ardiel, Laura J. Grundy, Chunmei Li, Jacque-Lynne Johnson, Julie Kennedy, Oliver E. Blacque, William R. Schafer, Catharine H. Rankin & Michel R. Leroux
Neurons throughout the mammalian brain possess non-motile cilia, organelles with varied functions in sensory physiology and cellular signaling, yet their roles in these neurons are poorly understood. To shed light into their functions, we studied EFHC1, an evolutionarily conserved protein required for motile cilia function and linked to a common form of inherited epilepsy in humans, juvenile myoclonic epilepsy (JME). We demonstrate that C. elegans EFHC1 functions within specialized non-motile mechanosensory cilia, where it regulates...

Data from: Using text-mined trait data to test for cooperate-and-radiate co-evolution between ants and plants

Katrina M. Kaur, Pierre-Jean G. Male, Erik Spence, Crisanto Gomez & Megan E. Frederickson
Mutualisms may be “key innovations” that spur lineage diversification by augmenting niche breadth, geographic range, or population size, thereby increasing speciation rates or decreasing extinction rates. Whether mutualism accelerates diversification in both interacting lineages is an open question. Research suggests that plants that attract ant mutualists have higher diversification rates than non-ant associated lineages. We ask whether the reciprocal is true: does the interaction between ants and plants also accelerate diversification in ants, i.e. do...

Data from: Survival is negatively related to basal metabolic rate in tropical Andean birds

Micah N. Scholer, Peter Arcese, Martin L. Puterman, Gustavo A. Londono & Jill E. Jankowski
1. Life history theory postulates that physiological traits, such as energy metabolism, can be understood in terms of allocation trade-offs between self-maintenance and reproduction over an organism’s lifespan, and data show that metabolic intensity and survival vary inversely with latitude, with tropical birds exhibiting a ‘slow’ pace of life relative to temperature species. However, tropical regions harbor strong environmental gradients of their own, and it remains to be shown whether similar life history trade-offs between...

Data from: Complex indirect effects of epiphytic bromeliads on the invertebrate food webs of their support tree

Pierre Rogy, Edd Hammill & Diane S. Srivastava
Ecosystem engineers are species that affect others through the provision of habitat rather than consumptive resources. The extent to which ecosystem engineers can indirectly affect entire food webs, however, is poorly understood. Epiphytic tank bromeliads (Bromeliaceae) are ecosystem engineers that are common throughout the Neotropics, and are associated with a variety of predatory arthropods. Here, we examine if bromeliads, by increasing predator densities, indirectly benefit their support tree through reduction in herbivorous insects and leaf...

Data from: Parallel changes in gut microbiome composition and function during colonization, local adaptation and ecological speciation

Diana J. Rennison, Seth M. Rudman & Dolph Schluter
The processes of local adaptation and ecological speciation are often strongly shaped by biotic interactions such as competition and predation. One of the strongest lines of evidence that biotic interactions drive evolution comes from repeated divergence of lineages in association with repeated changes in the community of interacting species. Yet, relatively little is known about the repeatability of changes in gut microbial communities and their role in adaptation and divergence of host populations in nature....

Data from: Rattus population genomics across the Haida Gwaii archipelago provides a framework for guiding invasive species management

Bryson Sjodin, Robyn Irvine, Adam Ford, Gregg Howald & Michael Russello
Invasive species have led to precipitous declines in biodiversity, especially in island systems. Brown (Rattus norvegicus) and black rats (R. rattus) are among the most invasive animals on the planet, with eradication being the primary tool for established island populations. The need for increased research for defining eradication units and monitoring outcomes has been highlighted as a means to maximize success. Haida Gwaii is an archipelago ~100 km off the northern coast of British Columbia,...

Data from: Grizzly bear response to fine spatial and temporal scale spring snow cover in Western Alberta

Ethan E. Berman, Nicholas C. Coops, Sean P. Kearney & Gordon B. Stenhouse
Snow dynamics influence seasonal behaviors of wildlife, such as denning patterns and habitat selection related to the availability of food resources. Under a changing climate, characteristics of the temporal and spatial patterns of snow are predicted to change, and as a result, there is a need to better understand how species interact with snow dynamics. This study examines grizzly bear (Ursus arctos) spring habitat selection and use across western Alberta, Canada. Made possible by newly...

Data from: Reciprocal abundance shifts of the intertidal sea stars, Evasterias troschelii and Pisaster ochraceus, following sea star wasting disease

Sharon Kay, Alyssa-Lois Gehman & Christopher Harley
Disease emergence occurs within the context of ecological communities, and disease driven declines in host populations can lead to complex direct and indirect ecological effects. Varying effects of a single disease among multiple susceptible hosts could benefit relatively resistant species. Beginning in 2013, an outbreak of sea star wasting disease (SSWD) led to population declines of many sea star species along the west coast of North America. Through field surveys and laboratory experiments, we investigated...

Data from: Reproductive losses due to climate change-induced earlier flowering are not the primary threat to plant population viability in a perennial herb

Amy M. Iler, Aldo Compagnoni, David W. Inouye, Jennifer L. Williams, Paul J. CaraDonna, Aaron Anderson & Tom E.X. Miller
1. Despite a global footprint of shifts in flowering phenology in response to climate change, the reproductive consequences of these shifts are poorly understood. Furthermore, it is unknown whether altered flowering times affect plant population viability. 2. We examine whether climate change-induced earlier flowering has consequences for population persistence by incorporating reproductive losses from frost damage (a risk of early flowering) in population models of a subalpine sunflower (Helianthella quinquenervis). Using long-term demographic data for...
