Data from: Refinement of a theoretical trait space for North American trees via environmental filtering

Michael Fell & Kiona Ogle
We refer to a theoretical trait space (TTS) as an n-dimensional hypervolume (“hypercube”) characterizing the range of values and covariations among multiple functional traits, in the absence of explicit filtering mechanisms. We previously constructed a 32-dimensional TTS for North American trees by fitting the Allometrically Constrained Growth and Carbon Allocation (ACGCA) model to USFS Forest Inventory and Analysis (FIA) data. Here, we sampled traits from this TTS, representing different individual “trees,” and subjected these trees...

Data from: Evidence for atypical nest overwintering by hatchling lizards, Heloderma suspectum

Dale T. DeNardo, Karla T. Moeller, Mark Seward, Roger Repp & Dale F. DeNardo
The timing of reproductive events (e.g., oviposition and hatching) to coincide with favorable seasonal conditions is critical for successful reproduction. However, developmental time may not match the duration between the optimal time for oviposition and the optimal time for hatchling survival. Thus, strategies that alter the time between oviposition and hatchling emergence can be highly advantageous. Arrested development and the resulting extension of the duration between oviposition and hatching has been widely documented across oviparous...

Data from: Social costs enforce honesty of a dynamic signal of motivation

Russell A. Ligon & Kevin J. McGraw
Understanding the processes that promote signal reliability may provide important insights into the evolution of diverse signaling strategies among species. The signals that animals use to communicate must comprise mechanisms that prohibit or punish dishonesty, and social costs of dishonesty have been demonstrated for several fixed morphological signals (e.g. color badges of birds and wasps). The costs maintaining the honesty of dynamic signals, which are more flexible and potentially cheatable, are unknown. Using an experimental...

Data from: Linking a mutation to survival in wild mice

Rowan D. H. Barrett, Stefan Laurent, Ricardo Mallarino, Susanne P. Pfeifer, Charles C. Y. Xu, Matthieu Foll, Kazumasa Wakamatsu, Jonathan S. Duke-Cohan, Jeffrey D. Jensen & Hopi E. Hoekstra
Adaptive evolution in new or changing environments can be difficult to predict because the functional connections between genotype, phenotype, and fitness are complex. Here, we make these explicit connections by combining field and laboratory experiments in wild mice. We first directly estimate natural selection on pigmentation traits and an underlying pigment locus, Agouti, by using experimental enclosures of mice on different soil colors. Next, we show how a mutation in Agouti associated with survival causes...

Data from: Regional paleoclimates and local consequences: Integrating GIS analysis of diachronic settlement patterns and process-based agroecosystem modeling of potential agricultural productivity in Provence (France)

Daniel Contreras, Eneko Hiriart, Alberte Bondeau, Alan Kirman, Joël Guiot, Loup Bernard, Romain Suarez, Sander Van Der Leeuw & Daniel A. Contreras
Holocene climate variability in the Mediterranean Basin is often cited as a potential driver of societal change, but the mechanisms of this putative influence are generally little explored. In this paper we integrate two tools - agro-ecosystem modeling of potential agricultural yields and spatial analysis of archaeological settlement pattern data - in order to examine the human consequences of past climatic changes. Focusing on a case study in Provence (France), we adapt an agro-ecosystem model...

Protocol for a Systematic Review and Meta-Analysis of Individual Participant Data on the Magnitude of Racial Disparities of Depressive Symptoms in the United States

José Causadias, Kevin Korous, Karina Cahill, Eiko Fried & Longfeng Li
A growing body of research has documented racial disparities in depressive symptoms in the United States, although the precise magnitude on these differences is less well understood. This issue has important implications for informing public health policy, and developing and administering prevention and intervention strategies. In this protocol, we propose a systematic review and meta-analysis of individual participant data from nationally representative studies from the United States drawn from Inter-university Consortium for Political and Social...

Data from: Verbalizing phylogenomic conflict: representation of node congruence across competing reconstructions of the neoavian explosion

Nico M. Franz, Lukas J. Musher, Joseph W. Brown, Yu Shizhuo & Bertram Ludäscher
Phylogenomic research is accelerating the publication of landmark studies that aim to resolve deep divergences of major organismal groups. Meanwhile, systems for identifying and integrating the products of phylogenomic inference–such as newly supported clade concepts–have not kept pace. However, the ability to verbalize node concept congruence and conflict across multiple, in effect simultaneously endorsed phylogenomic hypotheses, is a prerequisite for building synthetic data environments for biological systematics and other domains impacted by these conflicting inferences....

Data from: Invasion of Hawaiian rainforests by an introduced amphibian predator and N2-fixing tree increases soil N2O emissions

Sharon J. Hall, David P. Huber & R. Flint Hughes
Invasions of introduced species have homogenized ecological communities worldwide, leading to losses of native species and the services they provide. Some of these invaders substantially alter nutrient cycling, which changes conditions for all other organisms, but less is known about the potential influence of these species on nitrogen (N) trace gas emissions that affect atmospheric processes. We used a natural experiment to explore whether the establishment of an introduced nitrogen (N) fixing tree (Falcataria moluccana)...

Data from: Higher fat stores contribute to persistence of little brown bat populations with white-nose syndrome

Tina L. Cheng, Alexander Gerson, Marianne S. Moore, Jonathon D. Reichard, Joely DeSimone, Craig K.R. Willis, Winifred F. Frick & A. Marm Kilpatrick
1. The persistence of populations declining from novel stressors depends, in part, on their ability to respond by trait change via evolution or plasticity. White-nose syndrome (WNS) has caused rapid declines in several North America bat species by disrupting hibernation behavior, leading to body fat depletion and starvation. However, some populations of Myotis lucifugus now persist with WNS by unknown mechanisms. 2. We examined whether persistence of M. lucifigus with WNS could be explained by...

Data from: The hidden cost of sexually selected traits: the metabolic expense of maintaining a sexually selected weapon

Ummat Somjee, H. Arthur Woods, Meghan Duell & Christine W. Miller
Sexually selected weapons are among the most exaggerated traits in nature. Theory frequently assumes a high cost of this exaggeration; yet, those costs are rarely measured. We know very little about the energetic resources required to maintain these traits at rest and the difference in energetic costs for the largest relative to the smallest individuals. Knowledge in this area is crucial; resting metabolic rate can account for 30-40% of daily energy expenditure in wild animals....

Data from: It's not just what you have, but how you use it: solar-positional and behavioral effects on hummingbird color appearance during courtship

Richard K. Simpson & Kevin J. McGraw
Animals exhibit a diversity of colors that can play key roles in mating interactions. However, we presently lack an understanding of the relative importance of the environment, behavior, and natural reflective properties of colorful ornaments on an individual’s color appearance during mating-displays. We investigated interactions among structurally-based plumage, display environments, and courtship shuttle displays of male Costa's hummingbirds (Calypte costae) to test how these elements may differentially contribute to color appearance during shuttles. Male position...

Data from: Phylogenetic patterns of trait and trait plasticity evolution: Insights from amphibian embryos

Rick Relyea, Patrick R. Stephens, Lisa N. Barrow, Andrew Blaustein, Paul Bradley, Julia Buck, Ann Chang, Brian I Crother, James Collins, Julia Earl, Stephanie S. Gervasi, Jason T. Hoverman, Olliver Hyman, Emily Claire Moriarty Lemmon, Thomas Luhring, Moses Michelsohn, Christopher M. Murray, Steven Price, Raymond Semlitsch, Andy Sih, Aaron Stoler, Nick VandenBroek, Alexa Warwick, Greta Wengert, John Hammond … & Aaron B. Stoler
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: Rapid antagonistic coevolution in an emerging pathogen and its vertebrate host

Camille Bonneaud, Mathieu Giraudeau, Luc Tardy, Molly Staley, Geoffrey E. Hill & Kevin J. McGraw
Host-pathogen coevolution is assumed to play a key role in eco-evolutionary processes, including epidemiological dynamics and the evolution of sexual reproduction [1-4]. Despite this, direct evidence for host-pathogen coevolution is exceptional [5-7], particularly in vertebrate hosts. Indeed, although vertebrate hosts have been shown to evolve in response to pathogens or vice versa [8-12], there is little evidence for the necessary reciprocal changes in the success of both antagonists over time [13]. Here, we generate a...

Data from: A multispecies coalescent model for quantitative traits

Fabio K. Mendes, Jesualdo A. Fuentes-González, Joshua G. Schraiber & Matthew W. Hahn
We present a multispecies coalescent model for quantitative traits that allows for evolutionary inferences at micro- and macroevolutionary scales. A major advantage of this model is its ability to incorporate genealogical discordance underlying a quantitative trait. We show that discordance causes a decrease in the expected trait covariance between more closely related species relative to more distantly related species. If unaccounted for, this outcome can lead to an overestimation of a trait's evolutionary rate, to...

Data from: Age-specific patterns of maternal investment in common gull egg yolk

Janek Urvik, Kalev Rattiste, Mathieu Giraudeau, Monika Okuliarova, Peeter Horak & Tuul Sepp
While the general patterns of age-specific changes in reproductive success are quite well established in long-lived animals, we still do not know if allocation patterns of maternally-transmitted compounds are related to maternal age. We measured yolk testosterone, carotenoids and vitamins A and E levels in a population of known-aged common gulls (Larus canus) and found an age-specific pattern in yolk lutein and vitamin A concentrations. Middle-aged mothers allocated more of these substances to yolk compared...

Data from: The shortfall of sociality: group-living affects hunting performance of individual social spiders

Gyan Harwood & Leticia Avilés
Ineffective hunters in cooperative foraging groups may be shielded from natural selection by their more effective group mates, whereas those living solitarily would starve and thus be removed from the population. The problem may be exacerbated in large groups where it may be easier for individuals to withhold participation. Group foragers may thus be ineffective individual hunters or exhibit greater inter-individual variation in hunting abilities, in particular when living in large groups. We test these...

Data from: Plastic collective endothermy in a complex animal society (army ant bivouacs: Eciton burchellii parvispinum)

Kaitlin M. Baudier, Catherine L. D'Amelio, Elisabeth Sulger, Michael P. O'Connor & Sean O'Donnell
Endothermic animals do not always have a single adaptive internal temperature; some species exhibit plastic homeostasis, adaptively allowing body temperature to drop when thermoregulatory costs are high. Like large-bodied endotherms, some animal societies exhibit collective thermal homeostasis. We tested for plasticity of thermoregulation in the self-assembled temporary nests (bivouacs) of army ants. We measured core bivouac temperatures under a range of environmental conditions and at different colony developmental (larval vs. pupal brood) stages. Contrary to...

Data from: Structural and defensive roles of angiosperm leaf venation network reticulation across an Andes-Amazon elevation gradient

Benjamin Blonder, Norma Salinas, Lisa Patrick Bentley, Alexander Shenkin, Percy Orlando Chambi Porroa, Yolvi Valdez Tejeira, Tatiana Erika Boza Espinoza, Gregory R. Goldsmith, Lucas Enrico, Roberta Martin, Gregory P. Asner, Sandra Díaz, Brian J. Enquist & Yadvinder Malhi
1.The network of minor veins of angiosperm leaves may include loops (reticulation). Variation in network architecture has been hypothesized to have hydraulic and also structural and defensive functions. 2.We measured venation network trait space in eight dimensions for 136 biomass-dominant angiosperm tree species along a 3,300 m elevation gradient in southeastern Peru. We then examined the relative importance of multiple ecological, and evolutionary predictors of reticulation. 3.Variation in minor venation network reticulation was constrained to...

Data from: Juvenile social experience generates differences in behavioral variation but not averages

Nicholas DiRienzo, J. Chadwick Johnson & Anna Dornhaus
Developmental plasticity is known to influence the mean behavioral phenotype of a population. Yet, studies on how developmental plasticity shapes patterns of variation within populations are comparatively rare and often focus on a subset of developmental cues (e.g. nutrition). One potentially important but understudied developmental experience is social experience, as it is explicitly hypothesized to increase variation among individuals as a way to promote ‘social niches.’ To test this we exposed juvenile black widow spiders...
