Demographic data collection in STEM organizations

Nicholas Burnett, Alyssa Hernandez, Emily King, Richelle Tanner & Kathryn Wilsterman
Professional organizations in STEM (science, technology, engineering, and mathematics) can use demographic data to quantify recruitment and retention (R&R) of underrepresented groups within their memberships. However, variation in the types of demographic data collected can influence the targeting and perceived impacts of R&R efforts - e.g., giving false signals of R&R for some groups. We obtained demographic surveys from 73 U.S.-affiliated STEM organizations, collectively representing 712,000 members and conference-attendees. We found large differences in the...

Profiling, monitoring and conserving caterpillar fungus in the Himalayan region using anchored hybrid enrichment markers

Zhengyang Wang
The collection of caterpillar fungus accounts for 50-70% of the household income of thousands of Himalayan communities and has an estimated market value of $5-11 billion across Asia. However, Himalayan collectors are at multiple economic disadvantages compared with collectors on the Tibetan plateau because their product is not legally recognized. Using a customized hybrid-enrichment probe set and market-grade caterpillar fungus (with samples up to 30 years old) from 94 production zones across Asia, we uncovered...

Histological and life history data for small-bodied mammals from: Multituberculate mammals show evidence of a life history strategy similar to that of placentals, not marsupials

Lucas Weaver, Henry Fulghum, David Grossnickle, William Brightly, Zoe Kulik, Gregory Wilson Mantilla & Megan Whitney
The remarkable evolutionary success of placental mammals has been partly attributed to their reproductive strategy of prolonged gestation and birthing of relatively precocial, quickly weaned neonates. Although this strategy was conventionally considered derived relative to that of marsupials with highly altricial neonates and long lactation periods, mounting evidence has challenged this view. Until now, the fossil record has been relatively silent on this debate, but here we find that proportions of different bone tissue microstructures...

Changes in temperature alter competitive interactions and overall structure of fig wasp communities

Khin Me Me Aung, Huan-Huan Chen, Simon Segar, Yan-Qiong Peng & Cong Liu
1. Organisms exist within ecological networks, connected through interactions such as parasitism, predation and mutualism which can modify their abundance and distribution within habitat patches. Differential species responses make it hard to predict the influence of climate change at the community scale. Understanding the interplay between climate and biotic interactions can improve our predictions of how ecosystems will respond to current global warming. 2. We aim to understand how climate affects the multi-trophic biotic interactions...

The Total Carbon Column Observing Network (TCCON) is a network of ground-based Fourier Transform Spectrometers that record direct solar absorption spectra of the atmosphere in the near-infrared. From these spectra, accurate and precise column-averaged abundances of atmospheric constituents including CO2, CH4, N2O, HF, CO, H2O, and HDO, are retrieved. This is the GGG2020 data release of observations from the TCCON station at Indianapolis, Indiana, USA

Barcoded Bulk QTL mapping reveals highly polygenic and epistatic architecture of complex traits in yeast

Alex N. Nguyen Ba, Katherine Lawrence, Artur Rego-Costa, Shreyas Gopalakrishnan, Daniel Temko, Franziska Michor & Michael Desai
Mapping the genetic basis of complex traits is critical to uncovering the biological mechanisms that underlie disease and other phenotypes. Genome-wide association studies (GWAS) in humans and quantitative trait locus (QTL) mapping in model organisms can now explain much of the observed heritability in many traits, allowing us to predict phenotype from genotype. However, constraints on power due to statistical confounders in large GWAS and smaller sample sizes in QTL studies still limit our ability...

Doryteuthis pealeii embyronic transcriptome individual stages 16-27 pooled and annotation

Kristen Koenig
Photoreception is a ubiquitous sensory ability found across the Metazoa, and photoreceptive organs are intricate and diverse in their structure. Although the morphology of the compound eye in Drosophila and the single-chambered eye in vertebrates have elaborated independently, the amount of conservation within the 'eye' gene regulatory network remains controversial, with few taxa studied. To better understand the evolution of photoreceptive organs, we established the cephalopod Doryteuthis pealeii as a lophotrochozoan model for eye development....

Fine-scale genome-wide signature of Pleistocene glaciation in Thitarodes moths (Lepidoptera: Hepialidae), host of Ophiocordyceps fungus in the Hengduan Mountains

Zhengyang Wang & Naomi Pierce
The Hengduan Mountains region is a biodiversity hotspot known for its topologically complex, deep valleys and high mountains. While landscape and glacial refugia have been evoked to explain patterns of inter-species divergence, the accumulation of intra-species (i.e. population level) genetic divergence across the mountain-valley landscape in this region has received less attention. We used genome-wide restriction site-associated DNA sequencing (RADseq) to reveal signatures of Pleistocene glaciation in populations of Thitarodes shambalaensis (Lepidoptera: Hepialidae), the host...

Data from: Ontogeny and evolution of the elasmosaurid neck highlight a greater diversity of Antarctic plesiosaurians

Arthur S. Brum, Tiago R. Simões, Geovane A. Souza, André E. P. Pinheiro, Rodrigo G. Figueiredo, Michael W. Caldwell, Juliana M. Sayão & Alexander W. A. Kellner
The Antarctic plesiosaurian record is critical for understanding the evolution of elasmosaurids in the southern hemisphere. Elasmosaurids exhibit some of the most remarkable modifications of the vertebrate axial skeleton given their extreme elongation of the cervical region. Despite a considerable amount of information available on vertebral counts within Plesiosauria throughout the decades, we have a considerably more limited understanding of the diversity of cervical vertebral shapes in elasmosaurids and how these have changed throughout ontogeny...

β-cell-specific deletion of Zfp148 improves nutrient-stimulated β-cell Ca2+ responses

Christopher Emfinger, Alan Attie, Matthew Merrins, Eleonora De Klerk, Matthias Hebrok, Richard Kibbey, Rebecca Cardone, Kathryn Schueler, Mary Rabaglia, Shane Simonett, Donnie Stapleton, Kelly Mitok, Sophie Lewandowski, Ziyue Wang, Christina Kendziorski, Mark Keller, Hannah Foster, Stephen Gygi, Xinyue Liu, Joao Paulo, Qinq Yu & José Perales
Insulin secretion from pancreatic β-cells is essential for glucose homeostasis. An insufficient response to the demand for insulin results in diabetes. We previously showed that β-cell-specific deletion of Zfp148 (β-Zfp148KO) improves glucose tolerance and insulin secretion in mice. Here, we performed Ca2+ imaging of islets from β‑Zfp148KO and control mice on both a chow and a Western-style diet. β-Zfp148KO islets demonstrate improved sensitivity and sustained Ca2+ oscillations in response to elevated glucose. β-Zfp148KO islets also...

New opabiniid diversifies the weirdest wonders of the euarthropod stem group

Joanna Wolfe, Stephen Pates, Rudy Lerosey-Aubril, Allison C. Daley & Javier Ortega-Hernández
Once considered ‘weird wonders’ of the Cambrian, the emblematic Burgess Shale animals Anomalocaris and Opabinia are now recognized as lower stem group euarthropods and have provided crucial data for constraining the polarity of key morphological characters in the group. Anomalocaris and its relatives (radiodonts) had a worldwide distribution and survived until at least the Devonian. However, despite intense study, Opabinia remains the only formally described opabiniid to date. Here we reinterpret a fossil from the...

Perry
Human culture, biology, and health were shaped dramatically by the onset of agriculture ~12,000 years before present (BP). This shift is hypothesized to have resulted in increased individual fitness and population growth as evidenced by archaeological and population genomic data alongside a decline in physiological health as inferred from skeletal remains. Here, we consider osteological and ancient DNA data from the same prehistoric individuals to study human stature variation as a proxy for health across...

Limited increases in savanna carbon stocks over decades of fire suppression

Yong Zhou, Jenia Singh, John Butnor, Corli Coetsee, Peter Boucher, Madelon Case, Evan Hockridge, Andrew Davies & Carla Staver
Savannas cover a fifth of the land surface and contribute a third of terrestrial net primary production, accounting for three quarters of global area burned and over half of global fire-driven carbon emissions. Fire suppression and afforestation have been proposed as tools to increase carbon sequestration in these ecosystems. A robust quantification of whole-ecosystem carbon storage in savannas is lacking, however, especially under altered fire regimes. Here, we provide the first direct estimates of whole-ecosystem...

Deep-sequence phylogenetics to quantify patterns of HIV transmission in the context of a universal testing and treatment trial – BCPP/ Ya Tsie trial

Lerato Magosi, Yinfeng Zhang, Tanya Golubchik, Victor DeGruttola, Eric Tchetgen Tchetgen, Vladimir Novitsky, Janet Moore, Pam Bachanas, Tebogo Segolodi, Refeletswe Lebelonyane, Molly Pretorius Holme, Sikhulile Moyo, Joseph Makhema, Shahin Lockman, Christophe Fraser, Myron Essex & Marc Lipsitch
Background: Mathematical models predict that community-wide access to HIV testing-and-treatment can rapidly and substantially reduce new HIV infections. Yet several large universal test-and-treat HIV prevention trials in high-prevalence epidemics demonstrated variable reduction in population-level incidence. Methods: To elucidate patterns of HIV spread in universal test-and-treat trials we quantified the contribution of geographic-location, gender, age and randomized-HIV-intervention to HIV transmissions in the 30-community Ya Tsie trial in Botswana (estimated trial population: 175,664). Results: Deep-sequence phylogenetic analysis...

Data for: A hypothesis to explain polarization color vision in butterflies, with an example from the Australian Imperial Blue, Jalmenus evagoras

Richard Rabideau Childers
The Australian lycaenid butterfly, Jalmenus evagoras, has iridescent wings that are sexually dimorphic in both spectral reflection and degree of polarization, suggesting that these wing properties are likely to be important in mate recognition. We first describe the results of a field experiment showing that free-flying individuals of J. evagoras can discriminate between visual stimuli that vary in polarization content in a wavelength-dependent manner. We then present detailed reflectance spectrophotometry measurements of the polarization content...

Data from: Taxonomic scale and community organization impact observed latitudinal gradients of parasite diversity

Whitney Preisser
Aim: While most free-living taxa follow the latitudinal diversity gradient (LDG), or the trend of higher diversity at lower latitudes, we know little about how the diversity of parasitic taxa is distributed across latitudes. To better understand the macroecological patterns of parasite diversity, we sought to determine if: 1) helminths follow the traditional LDG; 2) taxonomic resolution impacts observed patterns; 3) latitudinal patterns are consistent across levels of community organization; and 4) helminth diversity is...

Data from: Fixation and preservation contribute to distortion in vertebrate museum specimens: a ten-year study with the lizard Anolis sagrei

R. Graham Reynolds, Inbar Maayan, Rachel M. Goodman, Paul M. Hime, Ryan Bickel, E. Allen Luck & Jonathan B. Losos
Preservation of museum specimens depends on chemical fixation and preservation, processes that might distort the original material. Relatively few studies have examined preservation effects in potentially susceptible soft-bodied taxa like herpetofauna, and those that have rarely extend over more than a few months. We collected six common morphological measurements from the same set of radiographed specimens of the Neotropical lizard Anolis sagrei over nearly ten years to investigate whether morphometric changes result from fixation in...

Data from: SARS-CoV-2 antibody dynamics in blood donors and COVID-19 epidemiology in eight Brazilian state capitals

Schier, Patricia M. Inoue, Lilyane A. Xabregas, Myuki A. E. Crispim, Nelson Fraiji, Fernando L. V. Araujo … & Ester C. Sabino
The COVID-19 situation in Brazil is complex due to large differences in the shape and size of regional epidemics. Here we tested monthly blood donation samples for IgG antibodies from March 2020 to March 2021 in eight of Brazil’s most populous cities. The inferred attack rate of SARS-CoV-2 adjusted for seroreversion in December 2020, before the Gamma VOC was dominant, ranged from 19.3% (95% CrI 17.5% - 21.2%) in Curitiba to 75.0% (95% CrI 70.8%...

Data from: Environmental controls on African herbivore responses to landscapes of fear

Andrew Davies, Joris Cromsigt, Craig Tambling, Elizabeth Le Roux, Nicholas Vaughn, Dave Druce, David Marneweck & Gregory Asner
Herbivores balance forage acquisition with the need to avoid predation, often leading to tradeoffs between forgoing resources to avoid areas of high predation risk, or tolerating increased risk in exchange for improved forage. The outcome of these decisions is likely to change with varying resource levels, with herbivores altering their response to predation risk across heterogeneous landscapes. Such contrasting responses will alter the strength of non-consumptive predation effects, but are poorly understood in multiple- predator/multiple-prey...

Data from: The origins of cognitive flexibility in chimpanzees

Averill Cantwell, Joshua Buckholtz, Rebeca Atencia & Alexandra Rosati
Cognitive flexibility is a core component of executive function, a suite of cognitive capacities that enables individuals to update their behavior in dynamic environments. Human executive functions are proposed to be enhanced compared to other species, but this inference is based primarily on neuroanatomical studies. To address this, we examined the nature and origins of cognitive flexibility in chimpanzees, our closest living relatives. Across three studies, we examined different components of cognitive flexibility using reversal...
