Data from: Evidence for personality conformity, not social niche specialization in social jays

Kelsey McCune, Piotr Jablonski, Sang-Im Lee & Renee Ha
Animal personality traits are defined as consistent individual differences in behavior over time and across contexts. Occasionally this inflexibility results in maladaptive behavioral responses to external stimuli. However, in social groups inflexible behavioral phenotypes might be favored as this could lead to more predictable social interactions. Two hypotheses seek to describe the optimal distribution of personality types within groups. The social niche specialization hypothesis states that individuals within groups should partition social roles, like personality...

Data from: Fluidigm2PURC: automated processing and haplotype inference for double-barcoded PCR amplicons

Paul D. Blischak, Maribeth Latvis, Diego F. Morales-Briones, Jens C. Johnson, Verónica S. Di Stilio, Andrea D. Wolfe & David C. Tank
Premise of the Study: Targeted enrichment strategies for phylogenomic inference are a time‐ and cost‐efficient way to collect DNA sequence data for large numbers of individuals at multiple, independent loci. Automated and reproducible processing of these data is a crucial step for researchers conducting phylogenetic studies. Methods and Results: We present Fluidigm2PURC, an open source Python utility for processing paired‐end Illumina data from double‐barcoded PCR amplicons. In combination with the program PURC (Pipeline for Untangling...

Data from: A multi-decade experiment shows that fertilization by salmon carcasses enhanced tree growth in the riparian zone

Thomas P. Quinn, James M. Helfield, Catherine S. Austin, Rachel A. Hovel & Andrew G. Bunn
As they return to spawn and die in their natal streams, anadromous, semelparous fishes such as Pacific salmon import marine‐derived nutrients to otherwise nutrient‐poor freshwater and riparian ecosystems. Diverse organisms exploit this resource, and previous studies have indicated that riparian tree growth may be enhanced by such marine‐derived nutrients. However, these studies were largely inferential and did not account for all factors affecting tree growth. As an experimental test of the contribution of carcasses to...

Data from: Extreme heterogeneity of influenza virus infection in single cells

Alistair B. Russell, Cole Trapnell & Jesse D. Bloom
Viral infection can dramatically alter a cell's transcriptome. However, these changes have mostly been studied by bulk measurements on many cells. Here we use single-cell mRNA sequencing to examine the transcriptional consequences of influenza virus infection. We find extremely wide cell-to-cell variation in the productivity of viral transcription - viral transcripts comprise less than a percent of total mRNA in many infected cells, but a few cells derive over half their mRNA from virus. Some...

Data from: Leapfrogging the Mexican highlands: influence of biogeographical and ecological factors on the diversification of highland species

Itzue W. Caviedes-Solis & Adam D. Leaché
In order to understand the processes that generate and maintain diversity, it is important to disentangle the roles of ecology and geography in speciation. We investigated the biogeographical and ecological factors that influenced the diversification of tree frogs (genus Sarcohyla) in the Mexican highlands, a region with high levels of endemism. Using single nucleotide polymorphism data for 58 samples, we found support for seven distinct genetic clusters within the Sarcohyla bistincta species complex, corresponding to...

Data from: Primary productivity explains size variation across the Pallid bat’s (Antrozous pallidus) western geographic range

Rochelle M. Kelly, Rachel Friedman & Sharlene E. Santana
1. Body size is associated with many aspects of the life history, ecology, and physiology of animals. Within a species, body size can vary substantially across space and time, and the mechanisms generating these patterns have been the focus of evolutionary and ecology research. 2. Bergmann’s Rule predicts a negative relationship between body size and temperature across the geographic range of endothermic animals; larger animals have a lower surface to volume ratio, which would allow...

Data from: Environmental drivers of forest structure and stem turnover across Venezuelan tropical forests

Emilio Vilanova, Hirma Ramirez-Angulo, Armando Torres-Lezama, Gerardo Aymard, Luis Gámez, Cristabel Durán, Lionel Hernández, Rafael Herrera, Geertje Van Der Heijden, Oliver L. Phillips & Gregory J. Ettl
Using data from 50 long-term permanent plots from across Venezuelan forests in northern South America, we explored large-scale patterns of stem turnover, aboveground biomass (AGB) and woody productivity (AGWP), and the relationships between them and with potential climatic drivers. We used principal component analysis coupled with generalized least squares models to analyze the relationship between climate, forest structure and stem dynamics. Two major axes associated with orthogonal temperature and moisture gradients effectively described more than...

Data from: Quantifying uncertainty due to fission-fusion dynamics as a component of social complexity

Gabriel Ramos-Fernandez, Andrew J. King, Jacinta C. Beehner, Thore J. Bergman, Margaret C. Crofoot, Anthony Di Fiore, Julia Lehmann, Colleen M. Schaffner, Noah Snyder-Mackler, Klaus Zuberbühler, Filippo Aureli & Denis Boyer
Groups of animals (including humans) may show flexible grouping patterns, in which temporary aggregations or subgroups come together and split, changing composition over short temporal scales, i.e. fission and fusion). A high degree of fission-fusion dynamics may constrain the regulation of social relationships, introducing uncertainty in interactions between group members. Here we use Shannon's entropy to quantify the predictability of subgroup composition for three species known to differ in the way their subgroups come together...

Data from: A genomic evaluation of taxonomic trends through time in coast horned lizards (genus Phrynosoma)

Adam D. Leache, Matt T. McElroy, Anna Trinh & Matthew T. McElroy
Determining the boundaries between species and deciding when to describe new species are challenging practices that are particularly difficult in groups with high levels of geographic variation. The coast horned lizards (Phrynosoma blainvillii, P. cerroense, and P. coronatum) have an extensive geographic distribution spanning many distinctive ecological regions ranging from northern California to the Cape Region of Baja California, Mexico, and populations differ substantially with respect to external morphology across much of this range. The...

Data from: Leaf nutrients, not specific leaf area, are consistent indicators of elevated nutrient inputs

Jennifer Firn, James M. McGree, Eric Harvey, Habacuc Flores-Moreno, Martin Schütz, Yvonne M. Buckley, Elizabeth T. Borer, Eric W. Seabloom, Kimberly J. La Pierre, Andrew M. MacDougall, Suzanne M. Prober, Carly J. Stevens, Lauren L. Sullivan, Erica Porter, Emma Ladouceur, Charlotte Allen, Karine H. Moromizato, John W. Morgan, W. Stanley Harpole, Yann Hautier, Nico Eisenhauer, Justin P. Wright, Peter B. Adler, Carlos Alberto Arnillas, Jonathan D. Bakker … & Anita C. Risch
Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental treatments across 27 globally distributed grassland sites across 4 continents. We find that specific leaf area (leaf area per unit mass)—a commonly measured morphological trait inferring shifts between plant growth strategies—did not respond to up to four years of soil nutrient additions. Leaf nitrogen, phosphorus...

Data from: Self-reported functional status predicts post-operative outcomes in non-cardiac surgery patients with pulmonary hypertension

Aalap C. Shah, Kevin Ma, David Faraoni, Daniel C.S. Oh, G. Alec Rooke, Gail A. Van Norman & Daniel C. S. Oh
BACKGROUND: Pulmonary hypertension (PHTN) is associated with increased post-procedure morbidity and mortality. Pre-procedure echocardiography (ECHO) is a widely used tool for evaluation of these patients, but its accuracy in predicting post-procedure outcomes is unproven. Self-reported exercise tolerance has not been evaluated for operative risk stratification of PHTN patients. OBJECTIVE: We analyzed whether self-reported exercise tolerance predicts outcomes (hospi-tal length-of-stay [LOS], mortality and morbidity) in PHTN patients (WHO Class I - V) under-going anesthesia and surgery....

Data from: Animals alter precipitation legacies: trophic and ecosystem engineering effects on plant community temporal dynamics

Joshua B. Grinath, Nicolas Deguines, John W. Chesnut, Laura R. Prugh, Justin S. Brashares & Katharine N. Suding
1. Multi-year precipitation ‘legacies’ can have stronger effects on plant community composition than rainfall in the current growing season, but variation in the magnitude of these effects is not fully understood. Direct interactions between plants and animals, such as herbivory, and indirect interactions, such as ecosystem engineering (via changes in the physical environment), may influence precipitation legacies by altering mechanisms of lagged effects. However, the role of direct and indirect plant-animal interactions in determining the...

Data from: Geomagnetic field influences upward movement of young Chinook salmon emerging from nests

Nathan F. Putman, Michelle M. Scanlan, Amanda M. Pollock, Joseph P. O'Neil, Ryan B. Couture, Joseph S. Stoner, Thomas P. Quinn, Kenneth J. Lohmann, David L.G. Noakes & David L. G. Noakes
Organisms use a variety of environmental cues to orient their movements in three-dimensional space. Here, we show that the upward movement of young Chinook salmon (Oncorhynchus tshawytscha) emerging from gravel nests is influenced by the geomagnetic field. Fish in the ambient geomagnetic field travelled farther upwards through substrate than did fish tested in a field with the vertical component inverted. This suggests that the magnetic field is one of several factors that influences emergence from...

Data from: A global test of the cold-climate hypothesis for the evolution of viviparity of squamate reptiles

Liang Ma, Lauren B. Buckley, Raymond B. Huey & Wei-Guo Du
Aim The evolution of viviparity in squamate reptiles has attracted considerable scientific attention since the beginning of last century. The cold climate hypothesis posits that cold regions favor viviparity (and therefore the incidence of viviparous squamates is increased in these regions) because viviparous females can use thermoregulatory behavior to shorten embryonic developmental time and to reduce exposure of embryos to stressful temperatures. However, a rigorous global-scale test of the impact of viviparity on the developmental...

Data from: Variation in growth and developmental responses to supraoptimal temperatures near latitudinal range limits of gypsy moth Lymantria dispar (L.), an expanding invasive species

Lily M. Thompson, Trevor M. Faske, Nana Banahene, Dominique Grim, Salvatore J. Agosta, Dylan Parry, Patrick C. Tobin, Derek M. Johnson & Kristine L. Grayson
Variation in thermal performance within and between populations provides the potential for adaptive responses to increasing temperatures associated with climate change. Organisms experiencing temperatures above their optimum on a thermal performance curve exhibit rapid declines in function and these supraoptimal temperatures can be a critical physiological component of range limits. The gypsy moth, Lymantria dispar (L.) (Lepidoptera: Erebidae), is one of the best-documented biological invasions and factors driving its spatial spread are of significant ecological...

Data from: Urban nectarivorous bird communities in Cape Town, South Africa, are structured by ecological generalisation and resource distribution

Anina Coetzee, Phoebe Barnard & Anton Pauw
Biological communities are increasingly faced with novel urban habitats and their response may depend on a combination of biological and habitat traits. The response of pollinator species to urban habitats are of particular importance because all species involved in the pollination mutualism may be affected. Nectarivorous bird communities worldwide show varying tolerances to urban areas, but studies from Africa are lacking. We investigated nectarivorous bird communities in a medium-sized South African city and asked which...

Data from: Spatial heterogeneity in species composition constrains plant community responses to herbivory and fertilization

Dorothee Hodapp, Elizabeth T. Borer, W. Stanley Harpole, Eric M. Lind, Eric W. Seabloom, Peter B. Adler, Juan Alberti, Carlos A. Arnillas, Jonathan D. Bakker, Lori Biederman, Marc Cadotte, Elsa E. Cleland, Scott Collins, Philip A. Fay, Jennifer Firn, Nicole Hagenah, Yann Hautier, Oscar Iribarne, Johannes M.H. Knops, Rebecca L. McCulley, Andrew MacDougall, Joslin L. Moore, John W. Morgan, Brent Mortensen, Kimberly J. La Pierre … & Johannes M. H. Knops
Environmental change can result in substantial shifts in community composition. The associated immigration and extinction events are likely constrained by the spatial distribution of species. Still, studies on environmental change typically quantify biotic responses at single spatial (time series within a single plot) or temporal (spatial beta-diversity at single time points) scales, ignoring their potential interdependence. Here, we use data from a global network of grassland experiments to determine how turnover responses to two major...

Data from: Estimating infection prevalence: best practices and their theoretical underpinnings

Ian F. Miller, India Schneider-Crease, Charles L. Nunn & Michael P. Muehlenbein
Accurately estimating infection prevalence is fundamental to the study of population health, disease dynamics, and infection risk factors. Prevalence is estimated as the proportion of infected individuals (“individual-based estimation”), but is also estimated as the proportion of samples from which the disease-causing organisms are recovered (“anonymous estimation”). The latter method is often used when researchers lack information on individual host identity, which can occur during noninvasive sampling of wild populations or when the individual that...

Data from: Large mammal declines and the incipient loss of mammal-bird mutualisms in an African savanna ecosystem

Nathan Diplock, Kate Johnston, Antoine Mellon, Laura Mitchell, Madison Moore, Daniel Schneider, Alyssa Taylor, Jess Whitney, Kera Zegar, John Kioko & Christian Kiffner
Over the past half-century, large mammal populations have declined substantially throughout East Africa, mainly due to habitat loss and unsustainable direct exploitation. While it has been acknowledged that the loss of large mammals can have direct and cascading effects on community composition and ecosystem characteristics, limited quantitative work has been done on how declines of large herbivore populations impacts the abundance of mutualistic symbionts. Using a space-for-time observational approach, we quantified the large mammal community...

Data from: Influence of a growth hormone transgene on the genetic architecture of growth-related traits: a comparative analysis between transgenic and wild-type coho salmon

Miyako Kodama, Kerry A. Naish & Robert H. Devlin
Genetic engineering has been increasingly applied to many commercially important plant and animal species, generating phenotypic changes that are not observed in natural populations and creating genetic interactions that have not experienced natural selection. The degree to and way in which such human-induced genetic variation interacts with the rest of the genome is currently largely unknown. Integrating such information into ecological and risk assessment frameworks is crucial to understand the potential effects of genetically modified...

Data from: Population responses of common ravens to reintroduced gray wolves

Lauren E. Walker, John M. Marzluff, Matthew C. Metz, Aaron J. Wirsing, L. Monika Moskal, Daniel R. Stahler & Douglas W. Smith
1. Top predators have cascading effects throughout the food web but their impacts on scavenger abundance are largely unknown. Gray wolves (Canis lupus) provide carrion to a suite of scavenger species, including the common raven (Corvus corax). Ravens are wide-ranging and intelligent omnivores that commonly take advantage of anthropogenic food resources. In areas where they overlap with wolves, however, ravens are numerous and ubiquitous scavengers of wolf-acquired carrion. 2. We aimed to determine whether subsidies...

Data from: Heat tolerance is more variable than cold tolerance across species of Iberian lizards after controlling for intraspecific variation

Salvador Herrando-Pérez, Camila Monasterio, Wouter Beukema, Verónica Gomes, Francisco Gomes Ferri-Yáñez, Josabel Belliure, Steven L. Chown, Lauren B Buckley, David R. Vieites & Miguel B. Araújo
The widespread observation that heat tolerance is less variable than cold tolerance (‘cold-tolerance asymmetry’) leads to the prediction that species exposed to temperatures near their thermal maxima should have reduced evolutionary potential for adapting to climate warming. However, the prediction is largely supported by species-level global studies based on single estimates of both physiological metrics per taxon. We ask if cold-tolerance asymmetry holds for Iberian lizards after accounting for intraspecific variation in critical thermal maxima...

Data from: Optimal foraging or surplus killing: selective consumption and discarding of salmon by brown bears

Alexandra E. Lincoln & Thomas P. Quinn
Selective consumption of prey by predators, observed in many animals, is often attributed to optimal foraging. Consistent with this idea, brown bears (Ursus arctos) often exhibit partial consumption, feeding exclusively on lipid-rich tissues of Pacific salmon (Oncorhynchus spp.), and discarding remains. However, bears also kill and abandon salmon without consuming any tissue. These discarded fish may be consistent with optimal foraging choices if they are of poor quality and if bears have easy access to...

Data from: Suppression and facilitation of human neural responses

Michael-Paul Schallmo, Alexander M. Kale, Rachel Millin, Anastasia V. Flevaris, Zoran Brkanac, Richard A.E. Edden, Raphael A. Bernier, Scott Murray, Scott O Murray & Richard AE Edden
Efficient neural processing depends on regulating responses through suppression and facilitation of neural activity. Utilizing a well-known visual motion paradigm that evokes behavioral suppression and facilitation, and combining 5 different methodologies (behavioral psychophysics, computational modeling, functional MRI, pharmacology, and magnetic resonance spectroscopy), we provide evidence that challenges commonly held assumptions about the neural processes underlying suppression and facilitation. We show that: 1) both suppression and facilitation can emerge from a single, computational principle - divisive...

Data from: Social and ecological drivers of reproductive seasonality in geladas

Elizabeth Tinsley Johnson, Noah Snyder-Mackler, Amy Lu, Thore J. Bergman & Jacinta C. Beehner
Many non-seasonally breeding mammals demonstrate some degree of synchrony in births, which is generally associated with ecological factors that mediate fecundity. However, disruptive social events, such as alpha male replacements, also have the potential to affect the timing of female reproduction. Here, we examined reproductive seasonality in a wild population of geladas (Theropithecus gelada) living at high altitudes in an afro-alpine ecosystem in Ethiopia. Using 9 years of demographic data (2006-2014) we determined that, while...
