Data from: The Achilles' heel hypothesis: misinformed keystone individuals impair collective learning and reduce group success

Jonathan Pruitt, Colin Wright, Carl Keiser, Alexander DeMarco, Matt Grobis, Noa Pinter-Wollman, Matthew M. Grobis, Alex E. DeMarco, Carl N. Keiser, Jonathan N. Pruitt & Colin M. Wright
Many animal societies rely on highly influential keystone individuals for proper functioning. When information quality is important for group success, such keystone individuals have the potential to diminish group performance if they possess inaccurate information. Here we test whether information quality (accurate or inaccurate) influences collective outcomes when keystone individuals are the first to acquire it. We trained keystone or generic individuals to attack or avoid novel stimuli and implanted these seed individuals within groups...

Data from: Retracted: Individual and group performance suffers from social niche disruption

Kate L. Laskowski, Pierre-Olivier Montiglio & Jonathan N. Pruitt
THE ASSOCIATED ARTICLE HAS BEEN RETRACTED. Further use of this data is not recommended. See https://www.journals.uchicago.edu/doi/abs/10.1086/708066 The social niche specialization hypothesis predicts that animal personalities emerge as a result of individuals occupying different social niches within a group. Here we track individual personality and performance, and collective performance among groups of social spiders where we manipulated the familiarity of the group members. We show that individual personalities, as measured by consistent individual differences in boldness...

Data from: Greenhouse gas emissions from reservoir water surfaces: a new global synthesis

Bridget R. Deemer, John A. Harrison, Siyue Li, Jake J. Beaulieu, Tonya DelSontro, Nathan Barros, José F. Bezerra-Neto, Stephen M. Powers, Marco A. Dos Santos & J. Arie Vonk
Collectively, reservoirs created by dams are thought to be an important source of greenhouse gases (GHGs) to the atmosphere. So far, efforts to quantify, model, and manage these emissions have been limited by data availability and inconsistencies in methodological approach. Here, we synthesize reservoir CH4, CO2, and N2O emission data with three main objectives: (1) to generate a global estimate of GHG emissions from reservoirs, (2) to identify the best predictors of these emissions, and...

Data from: Herbivore impacts on marsh production depend upon a compensatory continuum mediated by salinity stress

Jeremy D. Long & Laura D. Porturas
Plant communities are disturbed by several stressors and they are expected to be further impacted by increasing anthropogenic stress. The consequences of these stressors will depend, in part, upon the ability of plants to compensate for herbivory. Previous studies found that herbivore impacts on plants can vary from negative to positive because of environmental control of plant compensatory responses, a.k.a. the Compensatory Continuum Hypothesis. While these influential studies enhanced our appreciation of the dynamic nature...

Data from: Heme pathway evolution in kinetoplastid protists

Ugo Pierre Cenci, Daniel Moog, Bruce A. Curtis, Goro Tanifuji, Laura Eme, Julius Lukeš & John M. Archibald
Background: Kinetoplastea is a diverse protist lineage composed of several of the most successful parasites on Earth, organisms whose metabolisms have coevolved with those of the organisms they infect. Parasitic kinetoplastids have emerged from free-living, non-pathogenic ancestors on multiple occasions during the evolutionary history of the group. Interestingly, in both parasitic and free-living kinetoplastids, the heme pathway—a core metabolic pathway in a wide range of organisms—is incomplete or entirely absent. Indeed, Kinetoplastea investigated thus far...

Data from: Does personality affect the ability of individuals to track and respond to changing conditions?

Julie Gibelli & Frédérique Dubois
One possibility for why individual differences in behavioral plasticity are frequently associated with differences in personality might be that variation in personality is functionally related to variation in cognition. Evidence supporting a link between personality and cognition, however, is still limited and contradictory. In this study, we then conducted a laboratory experiment with zebra finches (Taeniopygia guttata) aimed at examining the role of cognition in shaping individual differences in contextual plasticity (i.e., plasticity in behavior...

Data from: Species distributions, quantum theory, and the enhancement of biodiversity measures

Raimundo Real, A. Márcia Barbosa & Joseph W. Bull
Species distributions are typically represented by records of their observed occurrence at a given spatial and temporal scale. Such records are inevitably incomplete and contingent on the spatial-temporal circumstances under which the observations were made. Moreover, organisms may respond differently to similar environmental conditions at different places or moments, so their distribution is, in principle, not completely predictable. We argue that this uncertainty exists, and warrants considering species distributions as analogous to coherent quantum objects,...

Data from: From population genomics to conservation and management: a workflow for targeted analysis of markers identified using genome-wide approaches in Atlantic salmon Salmo salar

Tutku Aykanat, Meri Lindqvist, Victoria L. Pritchard, Craig R. Primmer, T. Aykanat, M. Lindqvist, V. L. Pritchard & C. R. Primmer
A genotyping assay for the Ion Torrent Ion PGM platform was developed for fast and cost-effective targeted genotyping of key single nucleotide polymorphisms (SNPs) earlier identified using a genome-wide SNP array in Atlantic salmon Salmo salar. The method comprised a simple primer design step for multiplex-polymerase chain reaction (PCR), followed by two rounds of Ion Torrent Ion PGM sequencing to empirically evaluate marker efficiency in large multiplexes and to optimise or exclude them when necessary....

Data from: A fresh approach reveals how dispersal shapes metacommunity structure in a human-altered landscape

Barbara J. Downes, Jill Lancaster, Alena Glaister & William D. Bovill
To understand species losses from disturbed landscapes, it is important to distinguish the effects of degraded environmental conditions from those caused by barriers to dispersal between habitat patches. To assess the relative importance of these effects, we developed a new approach using permutation and association tests applied to rank abundance data, using the invertebrate fauna of two rivers in two seasons. Our study streams were Hughes Creek and Seven Creeks, in south-eastern Australia, which have...

Data from: Can the Fisher-Lande process account for birds of paradise and other sexual radiations?

Stevan J. Arnold & Lynne Diane Houck
Models of the Fisher‐Lande process (FLP) have been used successfully to explore many aspects of evolution by sexual selection. Despite this success, quantitative tests of these models using data from sexual radiations are rare. Consequently, we do not know whether realistic versions of the FLP can account for the extent and the rate of evolution of sexually selected traits. To answer this question, we generalize the basic FLP model of sexual coevolution and compare predictions...

Data from: Identifying targets of selection in mosaic genomes with machine learning: applications in Anopheles gambiae for detecting sites within locally adapted chromosomal inversions

Qixin He & L. Lacey Knowles
Chromosomal inversions are important structural changes that may facilitate divergent selection when they capture co-adaptive loci in the face of gene flow. However, identifying selection targets within inversions can be challenging. The high degrees of differentiation between heterokaryotypes, as well as the differences in demographic histories of collinear regions compared with inverted ones, reduce the power of traditional outlier analyses for detecting selected loci. Here, we develop a new approach that uses discriminant functions informed...

Data from: Shifting agriculture supports more tropical forest birds than oil palm or teak plantations in Mizoram, northeast India

Jaydev Mandal & T. R. Shankar Raman
Conversion of tropical forests and diverse multicrop agricultural land to commercial monocultures is a conservation concern worldwide. In northeast India, landscapes under shifting agriculture (or jhum) practiced by tribal communities are increasingly being replaced by monoculture plantations (e.g., teak, oil palm). We compared oil palm and teak plantations, shifting agricultural fields, and forest fallows (0–8 yr regeneration) with tropical rainforest edge and interior sites in Dampa Tiger Reserve, Mizoram, India. Twenty replicate transects were surveyed...

Data from: Symbiont-mediated RNA interference in insects

Miranda M. A. Whitten, Paul D. Facey, Ricardo Del Sol, Lorena T. Fernandez, Meirwyn C. Evans, Jacob J. Mitchell, Owen G. Bodger & Paul J. Dyson
RNA interference (RNAi) methods for insects are often limited by problems with double-stranded (ds) RNA delivery, which restricts reverse genetics studies and the development of RNAi-based biocides. We therefore delegated to insect symbiotic bacteria the task of: (i) constitutive dsRNA synthesis and (ii) trauma-free delivery. RNaseIII-deficient, dsRNA-expressing bacterial strains were created from the symbionts of two very diverse pest species: a long-lived blood-sucking bug, Rhodnius prolixus, and a short-lived globally invasive polyphagous agricultural pest, Western...

Data from: Intra-ejaculate sperm selection in female zebra finches

Nicola Hemmings, Clair Bennison, Timothy R. Birkhead, C. Bennison, T. R. Birkhead & N. Hemmings
Among internal fertilizers, typically fewer than 1% sperm survive the journey through the oviduct. Several studies suggest that the sperm reaching the ovum—the ‘fertilizing set’—comprise a non-random sub-population, but the characteristics of this group remain unclear. We tested whether oviductal selection in birds results in a morphologically distinct subset of sperm, by exploiting the fact that the fertilizing set are trapped by the perivitelline layer of the ovum. We show that these sperm have remarkably...

Data from: Egg morphology fails to identify nests parasitized by conspecifics in common pochard: a test based on protein fingerprinting and including female relatedness

Adéla Petrželková, Hannu Pöysä, Petr Klvaňa, Tomáš Albrecht & David Hořák
Conspecific brood parasites lay eggs in nests of other females of the same species. A variety of methods have been developed and used to detect conspecific brood parasitism (CBP). Traditional methods may be inaccurate in detecting CBP and in revealing its true frequency. On the other hand more accurate molecular methods are expensive and time consuming. Eadie developed a method for revealing CBP based on differences in egg morphology. That method is based on Euclidean...

Data from: Pyramids of species richness: the determinants and distribution of species diversity across trophic levels

Shaun Turney, Christoper M. Buddle & Christopher M. Buddle
How species richness is distributed across trophic levels determines several dimensions of ecosystem functioning, including herbivory, predation, and decomposition rates. We perform a meta-analysis of 72 large published food webs to investigate their trophic diversity structure and possible endogenous, exogenous, and methodological causal variables. Consistent with classic theory, we found that published food webs can generally be described as ‘pyramids of species richness’. The food webs were more predator-poor, prey-rich and hierarchical than is expected...

Data from: Linking landscape-scale differences in forage to ungulate nutritional ecology

Kelly M. Proffitt, Mark Hebblewhite, Wibke Peters, Nicole Hupp & Julee Shamhart
Understanding how habitat and nutritional condition affect ungulate populations is necessary for informing management, particularly in areas experiencing carnivore recovery and declining ungulate population trends. Variations in forage species availability, plant phenological stage, and the abundance of forage make it challenging to understand landscape-level effects of nutrition on ungulates. We developed an integrated spatial modeling approach to estimate landscape-level elk (Cervus elaphus) nutritional resources in two adjacent study areas that differed in coarse measures of...

Data from: Unidirectional diploid–tetraploid introgression among British birch trees with shifting ranges shown by restriction site-associated markers

Jasmin Zohren, Nian Wang, Igor Kardailsky, James S. Borrell, Anika Joecker, Richard A. Nichols & Richard J. A. Buggs
Hybridization may lead to introgression of genes among species. Introgression may be bidirectional or unidirectional, depending on factors such as the demography of the hybridizing species, or the nature of reproductive barriers between them. Previous microsatellite studies suggested bidirectional introgression between diploid Betula nana (dwarf birch) and tetraploid B. pubescens (downy birch) and also between B. pubescens and diploid B. pendula (silver birch) in Britain. Here, we analyse introgression among these species using 51 237...

Data from: Ecological influences and morphological correlates of resting and maximal metabolic rates across teleost fish species

Shaun S. Killen, Douglas S. Glazier, Enrico L. Rezende, Timothy D. Clark, David Atkinson, Astrid S. T. Willener & Lewis G. Halsey
Rates of aerobic metabolism vary considerably across evolutionary lineages, but little is known about the proximate and ultimate factors that generate and maintain this variability. Using data for 131 teleost fish species, we performed a large-scale phylogenetic comparative analysis of how interspecific variation in resting and maximum metabolic rates (RMR and MMR, respectively) is related to several ecological and morphological variables. Mass- and temperature-adjusted RMR and MMR are highly correlated along a continuum spanning a...

Data from: Antiherbivore defenses alter natural selection on plant reproductive traits

Kenneth A. Thompson, Marc T. J. Johnson, Ken A. Thompson & Marc T.J. Johnson
While many studies demonstrate that herbivores alter selection on plant reproductive traits, little is known about whether antiherbivore defenses affect selection on these traits. We hypothesized that antiherbivore defenses could alter selection on reproductive traits by altering trait expression through allocation trade-offs, or by altering interactions with mutualists and/or antagonists. To test our hypothesis, we used white clover, Trifolium repens, which has a Mendelian polymorphism for the production of hydrogen cyanide—a potent antiherbivore defense. We...

Data from: Specific alleles at immune genes, rather than genome-wide heterozygosity, are related to immunity and survival in the critically endangered Attwater's prairie-chicken

Zachary W. Bateson, Susan C. Hammerly, Jeff A. Johnson, Michael E. Morrow, Linda A. Whittingham & Peter O. Dunn
The negative effects of inbreeding on fitness are serious concerns for populations of endangered species. Reduced fitness has been associated with lower genome-wide heterozygosity and immune gene diversity in the wild; however, it is rare that both types of genetic measures are included in the same study. Thus, it is often unclear whether the variation in fitness is due to the general effects of inbreeding, immunity-related genes or both. Here, we tested whether genome-wide heterozygosity...
