Data from: Effects of warming on predator–prey interactions – a resource-based approach and a theoretical synthesis

Wojciech Uszko, Sebastian Diehl, Göran Englund & Priyanga Amarasekare
We theoretically explore consequences of warming for predator-prey dynamics, broadening previous approaches in three ways: we include beyond-optimal temperatures, predators may have a type III functional response, and prey carrying capacity depends on explicitly modeled resources. Several robust patterns arise. The relationship between prey carrying capacity and temperature can range from near-independence to monotonically declining/increasing to hump-shaped. Predators persist in a U-shaped region in resource supply (=enrichment)-temperature space. Type II responses yield stable persistence in...

Data from: Social associations between California sea lions influence the use of a novel foraging ground

Zachary A. Schakner, Daniel T. Blumstein & Matthew B. Petelle
Social relationships define an individual's position in its social network, which can influence the acquisition and spread of information and behavioural variants through the population. Thus, when nuisance behaviours spread through wildlife populations, identifying central individuals may provide valuable insights for problem-species management. We studied the effects of network position on California sea lion (Zalophus californianus) discovery and foraging success at a novel foraging ground—the salmonids that aggregate at the Bonneville Dam tail-race, 235 km...

Data from: Detecting signals of chronic shedding to explain pathogen persistence: Leptospira interrogans in California sea lions

Michael G. Buhnerkempe, Katherine C. Prager, Christopher C. Strelioff, Denise J. Greig, Jeff L. Laake, Sharon R. Melin, Robert L. DeLong, Frances M. D. Gulland & James O. Lloyd-Smith
Identifying mechanisms driving pathogen persistence is a vital component of wildlife disease ecology and control. Asymptomatic, chronically infected individuals are an oft-cited potential reservoir of infection but demonstrations of the importance of chronic shedding to pathogen persistence at the population level remain scarce. Studying chronic shedding using commonly collected disease data is hampered by numerous challenges, including short-term surveillance that focuses on single epidemics and acutely ill individuals, the subtle dynamical influence of chronic shedding...

Data from: Genetic assignment with isotopes and habitat suitability (GAIAH), a migratory bird case study

Kristen C. Ruegg, Eric C. Anderson, Ryan J. Harrigan, Kristina L. Paxton, Jeffrey F. Kelly, Frank Moore & Thomas B. Smith
1. Identifying migratory connections across the annual cycle is important for studies of migrant ecology, evolution, and conservation. While recent studies have demonstrated the utility of high-resolution SNP-based genetic markers for identifying population-specific migratory patterns, the accuracy of this approach relative to other intrinsic tagging techniques has not yet been assessed. 2. Here, using a straightforward application of Bayes' Rule, we develop a method for combining inferences from high-resolution genetic markers, stable isotopes, and habitat...

Data from: Cambrian origin of the CYP27C1-mediated vitamin A1-to-A2 switch, a key mechanism of vertebrate sensory plasticity

Ala Morshedian, Matthew B. Toomey, Gabriel E. Pollock, Rikard Frederiksen, Jennifer M. Enright, Stephen D. McCormick, M. Carter Cornwall, Gordon L. Fain & Joseph C. Corbo
The spectral composition of ambient light varies across both space and time. Many species of jawed vertebrates adapt to this variation by tuning the sensitivity of their photoreceptors via the expression of CYP27C1, an enzyme that converts vitamin A1 into vitamin A2, thereby shifting the ratio of vitamin A1-based rhodopsin to red-shifted vitamin A2-based porphyropsin in the eye. Here, we show that the sea lamprey (Petromyzon marinus), a jawless vertebrate that diverged from jawed vertebrates...

Data from: Sunrise in the city: disentangling drivers of the avian dawn chorus onset in urban greenspaces

Jeffrey G.-H. Lee, Ian MacGregor-Fors & Pamela J. Yeh
Urban systems are known to have a number of effects on avian richness, density, and morphological and behavioral traits. However, no study to date has simultaneously examined the wide range of urban variables in relation to the avian dawn chorus, a complex behavioral phenomenon. Previous studies investigating adjustments of the dawn chorus onset in urban settings have mainly been confined to relationships with noise and light levels. In addition to noise and light levels, in...

Data from: Is BAMM flawed? Theoretical and practical concerns in the analysis of multi-rate diversification models

Daniel L. Rabosky, Jonathan S. Mitchell & Jonathan Chang
BAMM (Bayesian Analysis of Macroevolutionary Mixtures) is a statistical framework that uses reversible jump MCMC to infer complex macroevolutionary dynamics of diversification and phenotypic evolution on phylogenetic trees. A recent article by Moore and coauthors (MEA) reported a number of theoretical and practical concerns with BAMM. Major claims from MEA are that (1) BAMM's likelihood function is incorrect, because it does not account for unobserved rate shifts; (2) the posterior distribution on the number of...

Data from: Body shape convergence driven by small size optimum in marine angelfishes

Bruno Frédérich, Francesco Santini, Nicolai Konow, Joseph Schnitzler, David Lecchini & Michael E. Alfaro
Convergent evolution of small body size occurs across many vertebrate clades and may reflect an evolutionary response to shared selective pressures. However it remains unclear if other aspects of phenotype undergo convergent evolution in miniaturized lineages. Here we present a comparative analysis of body size and shape evolution in marine angelfishes (Pomacanthidae), a reef fish family characterized by repeated transitions to small body size. We ask if lineages that evolve small sizes show convergent evolution...

Data from: Phylogenetic factor analysis

Max R. Tolkoff, Michael E. Alfaro, Guy Baele, Philippe Lemey & Marc A. Suchard
Phylogenetic comparative methods explore the relationships between quantitative traits adjusting for shared evolutionary history. This adjustment often occurs through a Brownian diffusion process along the branches of the phylogeny that generates model residuals or the traits themselves. For high-dimensional traits, inferring all pair-wise correlations within the multivariate diffusion is limiting. To circumvent this problem, we propose phylogenetic factor analysis (PFA) that assumes a small unknown number of independent evolutionary factors arise along the phylogeny and...

Data from: Recurrent myocardial infarction: mechanisms of free-floating adaptation and autonomic derangement in networked cardiac neural control

Guy Kember, Jeffrey Ardell, Kalyanam Shivkumar & J. Andrew Armour
The cardiac nervous system continuously controls cardiac function whether or not pathology is present. While myocardial infarction typically has a major and catastrophic impact, population studies have shown that longer-term risk for recurrent myocardial infarction and the related potential for sudden cardiac death depends mainly upon standard atherosclerotic variables and autonomic nervous system maladaptations. Investigative neurocardiology has demonstrated that autonomic control of cardiac function includes local circuit neurons for networked control within the peripheral nervous...

Data from: Fear no colors? Observer clothing color influences lizard escape behavior

Breanna J. Putman, Jonathan P. Drury, Daniel T. Blumstein & Gregory B. Pauly
Animals often view humans as predators, leading to alterations in their behavior. Even nuanced aspects of human activity like clothing color affect animal behavior, but we lack an understanding of when and where such effects will occur. The species confidence hypothesis posits that birds are attracted to colors found on their bodies and repelled by non-body colors. Here, we extend this hypothesis taxonomically and conceptually to test whether this pattern is applicable in a non-avian...

Data from: Substance P signalling in primary motor cortex facilitates motor learning in rats

Benjamin Hertler, Jonas Aurel Hosp, Manuel Buitrago Blanco & Andreas Rüdiger Luft
Among the genes that are up-regulated in response to a reaching training in rats, Tachykinin 1 (Tac1) - a gene that encodes the neuropeptide Substance P (Sub P) - shows an especially strong expression. Using Real-Time RT-PCR, a detailed time-course of Tac1 expression could be defined: a significant peak occurs 7 hours after training ended at the first and second training session, whereas no up-regulation could be detected at a later time-point (sixth training session)....

Data from: Strong social relationships are associated with decreased longevity in a facultatively social mammal

Daniel T. Blumstein, Dana M. Williams, Alexandra N. Lim, Svenja Kroeger, Julien G.A. Martin & Julien G. A. Martin
Humans in strong social relationships are more likely to live longer because social relationships may buffer stressors and thus have protective effects. However, a shortcoming of human studies is that they often rely on self-reporting of these relationships. By contrast, observational studies of nonhuman animals permit detailed analyses of the specific nature of social relationships. Thus, discoveries that some social animals live longer and healthier lives if they are involved in social grooming, forage together,...

Data from: Genomic signals of selection predict climate-driven population declines in a migratory bird

Rachael A. Bay, Ryan J. Harrigan, Vinh Le Underwood, H. Lisle Gibbs, Thomas B. Smith & Kristen C. Ruegg
The ongoing loss of biodiversity caused by rapid climatic shifts requires accurate models for predicting species’ responses. Despite evidence that evolutionary adaptation could mitigate climate change impacts, evolution is rarely integrated into predictive models. Integrating population genomics and environmental data, we identified genomic variation associated with climate across the breeding range of the migratory songbird, yellow warbler (Setophaga petechia). Populations requiring the greatest shifts in allele frequencies to keep pace with future climate change have...

Data from: Genomic divergence across ecological gradients in the Central African rainforest songbird (Andropadus virens)

Ying Zhen, Ryan J. Harrigan, Kristen C. Ruegg, Eric C. Anderson, Thomas C. Ng, Sirena Lao, Kirk E. Lohmueller & Thomas B. Smith
The little greenbul, a common rainforest passerine from sub-Saharan Africa, has been the subject of long-term evolutionary studies to understand the mechanisms leading to rainforest speciation. Previous research found morphological and behavioural divergence across rainforest–savannah transition zones (ecotones), and a pattern of divergence with gene flow suggesting divergent natural selection has contributed to adaptive divergence and ecotones could be important areas for rainforests speciation. Recent advances in genomics and environmental modelling make it possible to...

Data from: Issues and perspectives in species delimitation using phenotypic data: Atlantean evolution in Darwin's finches

Carlos Daniel Cadena, Felipe Zapata & Iván Jiménez
Progress in the development and use of methods for species delimitation employing phenotypic data lags behind conceptual and practical advances in molecular genetic approaches. The basic evolutionary model underlying the use of phenotypic data to delimit species assumes random mating and quantitative polygenic traits, so that phenotypic distributions within a species should be approximately normal for individuals of the same sex and age. Accordingly, two or more distinct normal distributions of phenotypic traits suggest the...

Data from: Feeding capability in the extinct giant Siamogale melilutra and comparative mandibular biomechanics of living Lutrinae

Z. Jack Tseng, Denise F. Su, Xiaoming Wang, Stuart C. White & Xueping Ji
At 50 kg in estimated weight, the extinct Siamogale melilutra is larger than all living otters, and ranks among the largest fossil otters. The biomechanical capability of S. melilutra jaws as related to their large size is unknown but crucial to reconstructing the species’ potentially unique ecological niche. Here we compare the mandibular biomechanics of S. melilutra using engineering-based performance measures against ten extant otter biomechanical models. Despite a wide range of feeding preferences from...

Data from: The roles of geography and environment in divergence within and between two closely related plant species inhabiting an island-like habitat

Artur Maria Wanderley, Isabel Cristina Sobreira Machado, Erton Mendonça De Almeida, Leonardo Pessoa Felix, Leonardo Galetto, Ana Maria Benko-Iseppon, Victoria L. Sork & Artur Maia Wanderley
Aim: In island-like habitats, geographic isolation facilitates population and species divergence by constraining gene flow, while environmental isolation can enhance divergence. We tested the relative contribution of geographic and environmental isolation in genetic and phenotypic divergence within and between two species of the figwort Ameroglossum (Scrophulariaceae) inhabiting spatially isolated habitats, known as inselbergs. Location: Borborema Plateau, north-eastern Brazil. Methods: Multivariate models of redundancy (RDAs) and partial redundancy analyses (pRDAs) were used to partition the geographic...

Data from: Life history strategy and everyday word use

Joseph H. Manson
Research by Sherman et al. (Journal of Personality and Social Psychology, 105, 873–888, 2013) has shown that, in speech during clinical-style interviews, life history strategy (LHS) was correlated with variation in the use of 16–19 word categories from the Linguistic Inquiry and Word Count program. However, links between individual difference variables and word use have been shown to vary as a function of communication context. Therefore, I sought to replicate their results using speech recorded...

Data from: Comparing forest structure and biodiversity on private and public land: secondary tropical dry forests in Costa Rica

Moana McClellan, Rebecca Montgomery, Kristen Nelson & Justin Becknell
Secondary forests constitute a substantial proportion of tropical forestlands. These forests occur on both public and private lands and different underlying environmental variables and management regimes may affect post‐abandonment successional processes and resultant forest structure and biodiversity. We examined whether differences in ownership led to differences in forest structure, tree diversity, and tree species composition across a gradient of soil fertility and forest age. We collected soil samples and surveyed all trees in 82 public...

Data from: Simultaneous synergist, antagonistic, and additive interactions between multiple local stressors all degrade algal turf communities on coral reefs

Caitlin R. Fong, Sarah J. Bittick & Peggy Fong
1.Ecological communities are subjected to multiple anthropogenic stressors at both global and local scales that are increasing in number and magnitude. Stressors can interact in complex ways, and are classified as additive, synergistic, or antagonistic; the nature of the interaction is key to predicting changes and understanding community resilience. Coral reefs are among the most impacted communities and have shifted from coral- to algal-dominated states, and overfishing, nutrient enrichment, and sedimentation are local stressors that...

Data from: The statistical mechanics of human weight change

John C. Lang, Hans De Sterck & Daniel M. Abrams
Over the past 35 years there has been a near doubling in the worldwide prevalence of obesity. Body Mass Index (BMI) distributions in high-income societies have increasingly shifted rightwards, corresponding to increases in average BMI that are due to well-studied changes in the socioeconomic environment. However, in addition to this shift, BMI distributions have also shown marked changes in their particular shape over time, exhibiting an ongoing right-skewed broadening that is not well understood. Here,...

Data from: Marine biodiversity at the end of the world: Cape Horn and Diego Ramírez islands

Alan M. Friedlander, Enric Ballesteros, Tom W. Bell, Jonatha Giddens, Brad Henning, Mathias Hüne, Alex Muñoz, Pelayo Salinas-De-León & Enric Sala
The vast and complex coast of the Magellan Region of extreme southern Chile possesses a diversity of habitats including fjords, deep channels, and extensive kelp forests, with a unique mix of temperate and sub-Antarctic species. The Cape Horn and Diego Ramírez archipelagos are the most southerly locations in the Americas, with the southernmost kelp forests, and some of the least explored places on earth. The giant kelp Macrocystis pyrifera plays a key role in structuring...
