Data from: Mother's social status is associated with child health in a horticulturalist population

Sarah Alami, Christopher Von Rueden, Edmond Seabright, Thomas S. Kraft, Aaron D. Blackwell, Jonathan Stieglitz, Hillard Kaplan & Michael Gurven
High social status is often associated with greater mating opportunities and fertility for men, but do women also obtain fitness benefits of high status? Greater resource access and child survivorship may be principal pathways through which social status increases women’s fitness. Here we examine whether peer-rankings of women’s social status (indicated by political influence, project leadership and respect) positively covaries with child nutritional status and health in a community of Amazonian horticulturalists. We find that...

Resource-related variables drive individual variation in flowering phenology and mediate population-level flowering responses to climate in an asynchronously reproducing palm

Tadeo Ramirez-Parada, Jordan Karubian, Luke Browne & Zoe Diaz-Martin
Many tropical plant species show wide intra-population variation in reproductive timing, resulting in the protracted presence of flowering and fruiting individuals. Various eco-evolutionary drivers have been proposed as ultimate causes for asynchronous phenology, yet little is known about the proximate factors that control reproductive onset among individuals, or that influence the proportion of trees producing new inflorescences within a population. We employed a nine-year phenological record from 178 individuals of the hyperdominant, asynchronously flowering canopy...

Disease's hidden death toll: Using parasite aggregation patterns to quantify landscape-level host mortality in a wildlife system

Mark Wilber, Cheryl Briggs & Pieter Johnson
Worldwide, infectious diseases represent a major source of mortality in humans and livestock. For wildlife populations, disease-induced mortality is likely even greater, but remains notoriously difficult to estimate -- especially for endemic infections. Approaches for quantifying wildlife mortality due to endemic infections have historically been limited by an inability to directly observe wildlife mortality in nature. Here, we address a question that can rarely be answered for endemic pathogens of wildlife: what are the population-...

Data from: Allometric scaling of metabolism is linked to colony aggressiveness in ants

Krista Kraskura, Thomas Lenihan, James Lichtenstein, Kirsten Sheehy, Grant Doering, Alexander Little, Jonathan Pruitt & Erika Eliason
These data are supplementary to a study entitled: "Allometric scaling of metabolism is linked to colony aggressiveness in ants". These data describe metabolic rates and behavior (aggressiveness) in ant colonies across size. The majority of scaling relationships are established on solitary organisms, but metabolism also scales allometrically with colony size in eusocial insect societies. One possible parameter that may affect metabolism in social insect colonies, is a colony’s collective behavioral phenotype. These data were collected...

Tsimane physiological dysregulation data

Thomas Kraft, Jonathan Stieglitz, Benjamin Trumble, Angela Garcia, Hillard Kaplan & Michael Gurven
Humans have the longest post-reproductive lifespans and lowest rates of actuarial aging among primates. Understanding the links between slow actuarial aging and physiological change is critical for improving the human “healthspan”. Physiological dysregulation may be a key feature of aging in industrialized populations with high burdens of chronic “diseases of civilization”, but little is known about age trajectories of physiological condition in subsistence populations with limited access to public health infrastructure. To better characterize human...

Robot Control Gestures (RoCoG)

Celso De Melo, Brandon Rothrock, Prudhvi Gurram, Oytun Ulutan & B.S. Manjunath
Building successful collaboration between humans and robots requires efficient, effective, and natural communication. This dataset supports the study of RGB-based deep learning models for controlling robots through gestures (e.g., “follow me”). To address the challenge of collecting high-quality annotated data from human subjects, synthetic data was considered for this domain. This dataset of gestures includes real videos with human subjects and synthetic videos from our custom simulator. This dataset can be used as a benchmark...

Detecting an effect of group size on individual responses to neighboring groups in gray-cheeked mangabeys (Lophocebus albigena)

Michelle Brown
Evolutionary game theory posits that competitive ability affects the initiation of conflicts. When contests occur among groups, competitive ability is generally measured as the size of the group and larger groups are expected to win against smaller groups. However, in some cases, individual participation during intergroup conflicts appears unaffected by competitive ability. To test whether these instances might be due to an unduly strict definition of participation, I re-evaluate the responses of grey-cheeked mangabeys (Lophocebus...

Fungal infection alters the selection, dispersal, and drift processes structuring the amphibian skin microbiome

Mark Q Wilber, Andrea J Jani, Joseph R Mihaljevic & Cheryl J Briggs
Symbiotic microbial communities are important for host health, but the processes shaping these communities are poorly understood. Understanding how community assembly processes jointly affect microbial community composition is limited because inflexible community models rely on rejecting dispersal and drift before considering selection. We developed a flexible community assembly model based on neutral theory to ask: How do dispersal, drift, and selection concurrently affect the microbiome across environmental gradients? We applied this approach to examine how...

Variations in the Intensity and Spatial Extent of Tropical Cyclone Precipitation

Danielle Touma, Samantha Stevenson, Suzana Camargo, Daniel Horton & Noah Diffenbaugh
The intensity and spatial extent of tropical cyclone precipitation (TCP) often shapes the risk posed by landfalling storms. Here we provide a comprehensive climatology of landfalling TCP characteristics as a function of tropical cyclone strength, using daily precipitation station data and Atlantic US landfalling tropical cyclone tracks from 1900-2017. We analyze the intensity and spatial extent of ≥ 1 mm/day TCP (Z1) and ≥ 50 mm/day TCP (Z50). We show that the highest median intensity...

Depth dependent azimuthal anisotropy beneath the Juan de Fuca plate system

Zachary Eilon & Donald Forsyth
We use surface wave measurements to reveal anisotropy as a function of depth within the Juan de Fuca and Gorda plate system. Using a two-plane wave method, we measure phase velocity and azimuthal anisotropy of fundamental mode Rayleigh waves, solving for anisotropic shear velocity. These surface wave measurements are jointly inverted with constraints from shear wave splitting studies using a Markov chain approach.

Land use change in California, 2001-2100

Keith Clarke & Michael Johnson
The SLEUTH urbanization and land use change model was used to produce century-long forecasts of California’s land uses to the year 2100. We describe how data were assembled and conflated for the model, how the model was applied to the very large and high resolution dataset, and how calibration of the model was performed using a genetic algorithm. The calibration results showed that the model accuracy was high, and suitable for simulations, which used Monte...

Data from: Hypoxia tolerance is unrelated to swimming metabolism of wild, juvenile striped bass (Morone saxatilis)

Krista Kraskura & Jay Nelson
Juvenile striped bass reside in the Chesapeake Bay where they are likely to encounter hypoxia that could affect their metabolism and performance. The ecological success of this economically valuable species may depend on their ability to tolerate hypoxia and perform fitness-dependent activities in hypoxic waters. We tested whether there is a link between hypoxia tolerance (HT) and oxygen consumption rate (MO2) of juvenile striped bass measured while swimming in normoxic and hypoxic water, and to...

Stepping into the past to conserve the future: archived skin swabs from extant and extirpated populations inform genetic management of an endangered amphibian

Andrew P. Rothstein, Roland A. Knapp, Gideon Bradburd, Daniel M. Boiano, Cheryl J. Briggs & Erica Bree Rosenblum
Moving animals on a landscape through translocations and reintroductions is an important management tool used in the recovery of endangered species, particularly for the maintenance of population genetic diversity and structure. Management of imperiled amphibian species rely heavily on translocations and reintroductions, especially for species that have been brought to the brink of extinction by the fungal pathogen, Batrachochytrium dendrobatidis. One striking example of disease-related declines and associated management efforts is in California’s Sequoia and...

Supporting information for: Comprehensive high‐precision relocation of seismicity on the Island of Hawai‘i 1986–2018: seismicity animations

Robin Matoza, Paul Okubo & Peter Shearer
Abundant seismicity beneath the the Island of Hawai‘i from mantle depths to the surface plays a central role in understanding how volcanoes work, grow, and evolve at this intraplate oceanic hotspot. We perform systematic waveform cross‐correlation, cluster analysis, and relative relocation of 347,445 events representing 32 years of seismicity on and around the island from 1986 to 2018. We successfully relocate 275,009 (79%) events using ∼1.7 billion differential times (P aicnd S) from ∼128 million...

Which Bank is the \"Central\" Bank? An Application of Markov Theory to the Canadian Large Value Transfer System

Morten Bech, James Chapman & Rod Garrat
We use a method similar to Google's PageRank procedure to rank banks in the Canadian Large Value Transfer System (LVTS). Along the way we obtain estimates of the payment processing speeds for the individual banks. These differences in processing speeds are essential for explaining why observed daily distributions of liquidity differ from the initial distributions, which are determined by the credit limits selected by banks.

Data from: Crop pests and predators exhibit inconsistent responses to surrounding landscape composition

Daniel S. Karp, Rebecca Chaplin-Kramer, Timothy D. Meehan, Emily A. Martin, Fabrice DeClerck, Heather Grab, Claudio Gratton, Lauren Hunt, Ashley E. Larsen, Alejandra Martínez-Salinas, Megan E. O’Rourke, Adrien Rusch, Katja Poveda, Mattias Jonsson, Jay A. Rosenheim, Nancy A. Schellhorn, Teja Tscharntke, Stephen D. Wratten, Wei Zhang, Aaron L. Iverson, Lynn S. Adler, Matthias Albrecht, Audrey Alignier, Gina M. Angelella, Muhammad Zubair Anjum … & Yi Zou
The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity in species responses to noncrop habitat may be biological in origin or could result from variation in how habitat and biocontrol are...

Data for: Sex-specific differences in swimming, aerobic metabolism, and recovery from exercise in adult coho salmon (Oncorhynchus kisutch) across ecologically relevant temperatures

Krista Kraskura, Emily Hardison & Erika Eliason
Adult female Pacific salmon can have highermigrationmortality rates thanmales, particularly at warm temperatures. However, the mechanisms underlying this phenomenon remain a mystery. Given the importance of swimming energetics on fitness, we measured critical swim speed, swimming metabolism, cost of transport, aerobic scope (absolute and factorial) and exercise recovery in adult female and male coho salmon (Oncorhynchus kisutch) held for 2 days at 3 environmentally relevant temperatures (9oC, 14oC, 18oC) in fresh water. Critical swimming performance...
