Data from: Population genetic structure of a common host predicts the spread of white-nose syndrome, an emerging infectious disease in bats

Aryn P. Wilder, Thomas H. Kunz & Michael D. Sorenson
Landscape complexity influences patterns of animal dispersal, which in turn may affect both gene flow and the spread of pathogens. White-nose syndrome (WNS) is an introduced fungal disease that has spread rapidly throughout eastern North America, causing massive mortality in bat populations. We tested for a relationship between the population genetic structure of the most common host, the little brown myotis (Myotis lucifugus), and the geographic spread of WNS to date by evaluating logistic regression...

Data from: Characterizing forest structure variations across an intact tropical peat dome using field samplings and airborne LiDAR

Ha T. Nguyen, Lucy R. Hutyra, Brady S. Hardiman & Steve M. Raciti
Tropical peat swamp forests (PSF) are one of the most carbon dense ecosystems on the globe and are experiencing substantial natural and anthropogenic disturbances. In this study we combined direct field sampling and airborne LiDAR to empirically quantify forest structure and aboveground live biomass (AGB) across a large, intact tropical peat dome in Northwestern Borneo. Moving up a 4m elevational gradient, we observed increasing stem density but decreasing canopy height, crown area and crown roughness....

Data from: Speciation genomics and a role for the Z chromosome in the early stages of divergence between Mexican ducks and mallards

Philip Lavretsky, Jeffrey M. DaCosta, Blanca E. Hernández-Baños, , Michael D. Sorenson, Jeffrey L. Peters & Andrew Engilis
Speciation is a continuous and dynamic process, and studying organisms during the early stages of this process can aid in identifying speciation mechanisms. The mallard (Anas platyrhynchos) and Mexican duck (A. [p.] diazi) are two recently diverged taxa with a history of hybridization and controversial taxonomy. To understand their evolutionary history, we conducted genomic scans to characterize patterns of genetic diversity and divergence across the mitochondrial DNA (mtDNA) control region, 3523 autosomal loci and 172...

Data from: Fog as a source of nitrogen for redwood trees: evidence from fluxes and stable isotopes

Pamela H. Templer, Kathleen C. Weathers, Holly A. Ewing, Todd E. Dawson, Stefania Mambelli, Amanda M. Lindsey, Jeramy Webb, Vanessa K. Boukili & Mary K. Firestone
A defining feature of the redwood forest in coastal California is the presence of fog in the summer months, a time when there is typically little rainfall. Our goal was to determine the role of summer fog in canopy transformation of nitrogen, nitrogen uptake by trees and photosynthesis within a coastal redwood forest ecosystem. We measured horizontal and vertical inputs of nitrogen, the isotopic composition of nitrogen in a variety of atmospheric sources (summer fog,...

Data from: The ontogeny of fairness in seven societies

Peter R. Blake, Katherine McAuliffe, John Corbit, Tara C. Callaghan, Oumar Barry, Aleah Bowie, Lauren Kleutsch, Karen L. Kramer, Elizabeth Ross, Hurnan Vongsachang, Richard Wrangham & Felix Warneken
A sense of fairness plays a critical role in supporting human cooperation. Adult norms of fair resource sharing vary widely across societies, suggesting that culture shapes the acquisition of fairness behaviour during childhood. Here we examine how fairness behaviour develops in children from seven diverse societies, testing children from 4 to 15 years of age (n = 866 pairs) in a standardized resource decision task. We measured two key aspects of fairness decisions: disadvantageous inequity...

Data from: Rapid diversification associated with ecological specialization in Neotropical Adelpha butterflies

Emily R. Ebel, Jeffrey M. DaCosta, Michael D. Sorenson, Ryan I. Hill, Adriana D. Briscoe, Keith R. Willmott & Sean P. Mullen
Rapid diversification is often associated with morphological or ecological adaptations that allow organisms to radiate into novel niches. Neotropical Adelpha butterflies, which comprise over 200 species and subspecies, are characterized by extraordinary breadth in host plant use and wing colour patterns compared to their closest relatives. To examine the relationship between phenotypic and species diversification, we reconstructed the phylogenetic history of Adelpha and its temperate sister genus Limenitis using genomewide restriction-site-associated DNA (RAD) sequencing. Despite...

Data from: Relation between stability and resilience determines the performance of early warning signals under different environmental drivers

Lei Dai, Kirill S. Korolev & Jeff Gore
Shifting patterns of temporal fluctuations have been found to signal critical transitions in a variety of systems, from ecological communities to human physiology. However, failure of these early warning signals in some systems calls for a better understanding of their limitations. In particular, little is known about the generality of early warning signals in different deteriorating environments. In this study, we characterized how multiple environmental drivers influence the dynamics of laboratory yeast populations, which was...

Data from: Lifespan behavioral and neural resilience in a social insect

Ysabel Milton Giraldo, J. Frances Kamhi, Vincent Fourcassié, Mathieu Moreau, Simon K. A. Robson, Adina Rusakov, Lindsey Wimberly, Alexandria Diloreto, Adrianna Kordek & James F. A. Traniello
Analyses of senescence in social species are important to understanding how group living influences the evolution of ageing in society members. Social insects exhibit remarkable lifespan polyphenisms and division of labour, presenting excellent opportunities to test hypotheses concerning ageing and behaviour. Senescence patterns in other taxa suggest that behavioural performance in ageing workers would decrease in association with declining brain functions. Using the ant Pheidole dentata as a model, we found that 120-day-old minor workers,...

Data from: Population genomic datasets describing the post-vaccine evolutionary epidemiology of Streptococcus pneumoniae

Nicholas J. Croucher, Jonathan A. Finkelstein, Steven I. Pelton, Julian Parkhill, Stephen D. Bentley, William P. Hanage & Marc Lipsitch
Streptococcus pneumoniae is common nasopharyngeal commensal bacterium and important human pathogen. Vaccines against a subset of pneumococcal antigenic diversity have reduced rates of disease, without changing the frequency of asymptomatic carriage, through altering the bacterial population structure. These changes can be studied in detail through using genome sequencing to characterise systematically-sampled collections of carried S. pneumoniae. This dataset consists of 616 annotated draft genomes of isolates collected from children during routine visits to primary care...

Data from: Polymorphism and division of labour in a socially complex ant: neuromodulation of aggression in the Australian weaver ant, Oecophylla smaragdina

J. Frances Kamhi, Kelley Nunn, Simon K. A. Robson & James F. A. Traniello
Complex social structure in eusocial insects can involve worker morphological and behavioural differentiation. Neuroanatomical variation may underscore worker division of labour, but the regulatory mechanisms of size-based task specialization in polymorphic species are unknown. The Australian weaver ant, Oecophylla smaragdina, exhibits worker polyphenism: larger major workers aggressively defend arboreal territories, whereas smaller minors nurse brood. Here, we demonstrate that octopamine (OA) modulates worker size-related aggression in O. smaragdina. We found that the brains of majors...

Data from: Post-metamorphic carry-over effects of larval digestive plasticity

Sarah S. Bouchard, Chelsea R. Jenney O'Leary, Lindsay J. Wargelin, Julie F. Charbonnier, Karen M. Warkentin & Chelsea J. O'Leary
For animals with complex life cycles, conditions in the larval environment can have important effects that persist after metamorphosis. These carry-over effects may influence juvenile growth plasticity and have important fitness consequences. Small juvenile red-eyed treefrogs, Agalychnis callidryas, grow faster than larger ones. We examined to what extent this growth pattern is due to carry-over effects of intraspecific larval competition. In particular, we assessed larval gut plasticity and determined whether carry-over effects could persist given...

Data from: Predicting species’ vulnerability in a massively perturbed system: the fishes of Lake Turkana, Kenya

Natasha J. Gownaris, Ellen K. Pikitch, William O. Ojwang, Robert Michener & Les Kaufman
Background and Trophic Diversity Study: Lake Turkana is an understudied desert lake shared by Kenya and Ethiopia. This system is at the precipice of large-scale changes in ecological function due to climate change and economic development along its major inflowing river, the Omo River. To anticipate response by the fish community to these changes, we quantified trophic diversity for seven ecological disparate species (Alestes baremose, Hydrocynus forskalli, Labeo horie, Lates niloticus, Oreochromis niloticus, Synodontis schall,...
