Genomic signatures of host-associated divergence and adaptation in a coral-eating snail, Coralliophila violacea (Kiener, 1836)

Sara Simmonds, Allison Fritts-Penniman, Samantha Cheng, Ngurah Mahardika & Paul Barber
The fluid nature of the ocean, combined with planktonic dispersal of marine larvae, lowers physical barriers to gene flow. However, divergence can still occur despite gene flow if strong selection acts on populations occupying different ecological niches. Here, we examined the population genomics of an ectoparasitic snail, Coralliophila violacea (Kiener 1836), that specializes on Porites corals in the Indo-Pacific. Previous genetic analyses revealed two sympatric lineages associated with different coral hosts. In this study, we...

Data from: A mechanistic and empirically-supported lightning risk model for forest trees

Evan Gora, Jeffrey Burchfield, Helene Muller-Landau, Phillip Bitzer, Stephen Hubbell & Stephen Yanoviak
Tree death due to lightning influences tropical forest carbon cycling and tree community dynamics. However, the distribution of lightning damage among trees in forests remains poorly understood. We developed models to predict direct and secondary lightning damage to trees based on tree size, crown exposure, and local forest structure. We parameterized these models using data on the locations of lightning strikes and censuses of tree damage in strike zones, combined with drone-based maps of tree...

Data from: The structure of the Mini-K and K-SF-42: a psychological network approach

Joseph Manson, Kristine Chua & Aaron Lukaszewski
Study-1-data and Study-2-data comprise responses to the Mini-K (Figueredo et al. 2006). The Study 1 participants were Amazon's Mechanincal Turk workers. The Study 2 participants were undergraduates at Oklahoma State University. Study-3-data comprises reponses to the K-SF-42 (Figueredo et al. 2017). Participants were Amazon's Mechanincal Turk workers. See the paper for additional information. R-code contains the code used to run the network analyses described in the paper. "Datafile" represents the file name of the data...

Relaxed random walks at scale

Alexander Fisher, Xiang Ji, Zhenyu Zhang, Philippe Lemey & Marc Suchard
Relaxed random walk (RRW) models of trait evolution introduce branch-specific rate multipliers to modulate the variance of a standard Brownian diffusion process along a phylogeny and more accurately model overdispersed biological data. Increased taxonomic sampling challenges inference under RRWs as the number of unknown parameters grows with the number of taxa. To solve this problem, we present a scalable method to efficiently fit RRWs and infer this branch-specific variation in a Bayesian framework. We develop...

Data from: A Search for Technosignatures Around 31 Sun-like Stars with the Green Bank Telescope at 1.15–1.73 GHz

Jean-Luc Margot, Pavlo Pinchuk, Robert Geil & Ryan Lynch
This dataset describes candidate signal detections obtained at the Green Bank Telescope in 2018 and 2019 and reprocessed with the 2020 UCLA SETI Group data processing pipeline. We conducted a search for technosignatures in April of 2018 and 2019 with the L-band receiver (1.15–1.73 GHz) of the 100 m diameter Green Bank Telescope. These observations focused on regions surrounding 31 Sun-like stars near the plane of the Galaxy. We present the results of our search...

Results of a Person-Centered Maternal Health Quality Improvement intervention in Uttar Pradesh, India

Dominic Montagu, May Sudhinaraset & Nadia Diamond-Smith
This data is from a larger 5 year project on person-centered quality for delivery, family planning, and abortion in both India and Kenya. We conducted a quality improvement collaborative to improve person-centered quality for maternal health services in Uttar Pradesh, India. Data was collected pre and post intervention. The aim was to evaluate if quality improvement cycles were effective at improving women's experiences while seeking care and if the changes made during this intervention could...

Evaluation of Person Centered-Care During Family Planning Services at Public Facilities in India

Dominic Montagu, May Sudhinaraset & Nadia Diamond-Smith
This data is from a larger 5 year project on person-centered quality for delivery, family planning, and abortion in both India and Kenya. This is the baseline data evaluating Person Centered Care during Family Planning services at Public Facilities in Uttar Pradesh, India.

Data from: A search for technosignatures from TRAPPIST-1, LHS 1140, and 10 planetary systems in the Kepler field with the Green Bank Telescope at 1.15–1.73 GHz

Jean-Luc Margot, Pavlo Pinchuk, Adam H. Greenberg, Thomas Ayalde, Chad Bloxham, Arjun Boddu, Luis Gerardo Chinchilla-Garcia, Micah Cliffe, Sara Gallagher, Kira Hart, Brayden Hesford, Inbal Mizrahi, Ruth Pike, Dominic Rodger, Bade Sayki, Una Schneck, Aysen Tan, & Ryan S. Lynch
This dataset includes candidate signal detections obtained at the Green Bank Telescope in 2017 and reprocessed with the 2020 UCLA SETI Group data processing pipeline. As part of our ongoing search for technosignatures, we collected over three terabytes of data in May 2017 with the L-band receiver (1.15–1.73 GHz) of the 100 m diameter Green Bank Telescope. These observations focused primarily on planetary systems in the Kepler field, but also included scans of the recently...

Data from: Large-scale assessment of intra- and inter-annual breeding success using a remote camera network

Casey Youngflesh, Fiona M. Jones, Heather J. Lynch, Joan Arthur, Zuzana Ročkaiová, Holly R. Torsey & Tom Hart
Changes in the physical environment along the Antarctic Peninsula have been among the most rapid anywhere on the planet. In concert with environmental change, the potential for direct human disturbance resulting from tourism, scientific programs, and commercial fisheries continues to rise in the region. While seabirds, such as the gentoo penguin Pygoscelis papua, are commonly used to assess the impact of these disturbances on natural systems, research efforts are often hampered by limited spatial coverage...

Data from: Soil microbes generate stronger fitness differences than stabilization among California annual plants

Gaurav Kandlikar, Xinyi Yan, Jonathan Levine & Nathan Kraft
Soil microorganisms influence a variety of processes in plant communities. Many theoretical and empirical studies have shown that dynamic feedbacks between plants and soil microbes can stabilize plant coexistence by generating negative frequency-dependent plant population dynamics. However, inferring the net effects of soil microbes on plant coexistence requires also quantifying the degree to which they provide one species an average fitness advantage, an effect that has received little empirical attention. We conducted a greenhouse study...

Data from: Is narcissism a slow life history strategy indicator? The answer depends on the LHS instrument

Joseph Manson
The Dark Triad (DT) traits are differentially related to psychometrically assessed life history strategy (LHS), such that psychopathy is strongly associated with a faster LHS whereas narcissism appears to be, if anything, a slow LHS indicator. However, the research supporting these generalizations has been based largely on undergraduate samples in which LHS has been measured using the Arizona Life History Battery (ALHB) (or its short version the Mini-K), an instrument that arguably lacks adequate coverage...
