Data from: A strengths-based data capture model: mining data-driven and person-centered health assets

Grace Gao, Madeleine J Kerr, Ruth A Lindquist, Chih-Lin Chi, Michelle A Mathiason, Robin R Austin & Karen A Monsen
With health care policy directives advancing value-based care, risk assessments and management have permeated health care discourse. The conventional problem-based infrastructure defines what data are employed to build this discourse and how it unfolds. Such a health care model tends to bias data for risk assessment and risk management toward problems and does not capture data about health assets or strengths. The purpose of this article is to explore and illustrate the incorporation of a...

Data from: Rethinking phylogenetic comparative methods

Josef C. Uyeda, Rosana Zenil-Ferguson & Matthew W. Pennell
As a result of the process of descent with modification, closely related species tend to be similar to one another in a myriad different ways. In statistical terms, this means that traits measured on one species will not be independent of traits measured on others. Since their introduction in the 1980s, phylogenetic comparative methods (PCMs) have been framed as a solution to this problem. In this paper, we argue that this way of thinking about...

Brancalion, George A. L. Cabral, Ricardo Gomes César, Robin L. Chazdon, Rebecca J. Cole, Gabriel Dalla Colletta, Ben De Jong, Julie S. Denslow, Daisy H. Dent, Saara J. DeWalt, Juan Manuel Dupuy, Sandra M. Durán, Mário Marcos Do Espírito Santo, G. Wilson Fernandes, Yule Roberta Ferreira Nunes … & Jennifer S. Powers
The nutrient demands of regrowing tropical forests are partly satisfied by nitrogen (N)-fixing legume trees, but our understanding of the abundance of those species is biased towards wet tropical regions. Here we show how the abundance of Leguminosae is affected by both recovery from disturbance and large-scale rainfall gradients through a synthesis of forest-inventory plots from a network of 42 Neotropical forest chronosequences. During the first three decades of natural forest regeneration, legume basal area...

Data from: Female investment in offspring size and number shifts seasonally in a lizard with single-egg clutches

Timothy S. Mitchell, Joshua M. Hall & Daniel A. Warner
The timing of reproduction strongly influences reproductive success in many organisms. For species with extended reproductive seasons, the quality of the environment may change throughout the season in ways that impact offspring survival, and, accordingly, aspects of reproductive strategies may shift to maximize fitness. Life-history theory predicts that if offspring environments deteriorate through the season, females should shift from producing more, smaller offspring early in the season to fewer, higher quality offspring later in the...

Data from: Dietary patterns during adulthood and cognitive performance in midlife: the CARDIA study

Claire T. McEvoy, Tina Hoang, Stephen Sidney, Lyn M. Steffen, David R. Jacobs, James M. Shikany, John T. Wilkins & Kristine Yaffe
Objective: To investigate whether dietary patterns (Mediterranean diet (MedDiet), Dietary Approaches to Stop Hypertension (DASH) and A Priori Diet Quality Score (APDQS)) during adulthood are associated with better midlife cognitive performance. Methods: We studied 2,621 CARDIA participants: 45% black, 57% female, and age 25±3.5 years at baseline (1985-6). Diet scores were calculated from repeated diet history up to year 20. Linear models were used to examine association between tertiles of diet score and year 25...

Data from: Extreme dentition does not prevent diet and tooth diversification within combtooth blennies (Ovalentaria: Blenniidae)

Peter Joseph Hundt & Andrew M. Simons
The dentition of fishes can be quite striking and is often correlated with a specific diet. Combtooth blennies have long incisiform oral teeth, unlike most actinopterygians. It has been suggested that the long tooth morphology is an adaptation for detritivory, but given the diversity of diets (detritus, coral polyps, polychaetes, and pieces of other fishes), are blenny teeth indeed monomorphic? Or does tooth variation associated with diet still exist at this extreme? To explore tooth...

Data from: Impacts of species richness on productivity in a large-scale subtropical forest experiment

Yuanyuan Huang, Yuxin Chen, Nadia Castro-Izaguirre, Martin Baruffol, Matteo Brezzi, Anne Lang, Ying Li, Werner Härdtle, Werner Von Oheimb, Xuefeu Yang, Xiaojuan Liu, Kequan Pei, Sabine Both, Bo Yang, David Eichenberg, Thorsten Assmann, Jürgen Bauhus, Thorsten Behrens, François Buscot, Xiao-Yong Chen, Douglas Chester, Bing-Yang Ding, Walter Durka, Alexandra Erfmeier, Jingyun Fang … & Bernhard Schmid
Biodiversity experiments have shown that species loss reduces ecosystem functioning in grassland. To test whether this result can be extrapolated to forests, the main contributors to terrestrial primary productivity, requires large-scale experiments. We manipulated tree species richness by planting more than 150,000 trees in plots with 1 to 16 species. Simulating multiple extinction scenarios, we found that richness strongly increased stand-level productivity. After 8 years, 16-species mixtures had accumulated over twice the amount of carbon...

Data from: Use of simulation-based statistical models to complement bioclimatic models in predicting continental scale invasion risks

Ranjan Muthukrishnan, Nicholas R. Jordan, Adam S. Davis & James D. Forester
Invasive species represent one of the greatest risks to global biodiversity and economic productivity of agroecosystems. The development of certain novel crops—e.g., herbaceous perennial biomass crops—may create a risk of novel invasions by these crops. Therefore, potential benefits and risks need to be weighed in making decisions about their introduction and subsequent management. Ideally, such a weighing will be based on good estimates of invasion risks in realistic scenarios pertaining to actual landscapes of concern...

Data from: Despite high levels of expression in thymic epithelial cells, miR-181a1 and miR-181b1 are not required for thymic development

Heather E. Stefanski, Yan Xing, Patricia A. Taylor, Stefano Maio, Jorge Henao-Meija, Adam Williams, Richard A. Flavell, Georg A. Hollander & Bruce R. Blazar
MicroRNAs (miRNAs) have been shown to be key modulators of post-transcriptional gene silencing in many cellular processes. In previous studies designed to understand the role of miRNAs in thymic development, we globally deleted miRNA exclusively in thymic epithelial cells (TECs), which are critical in thymic selection. This resulted in the loss of stromal cells that instruct T cell lineage commitment and affect thymocyte positive selection, required for mature T cell development. Since murine miR-181 is...

Data from: Pollination along an elevational gradient mediated both by floral scent and pollinator compatibility in the fig and fig‐wasp mutualism

Daniel Souto-Vilarós, Magali Proffit, Bruno Buatois, Michal Rindos, Mentap Sisol, Thomas Kuyaiva, Jan Michalek, Clive T. Darwell, Martine Hossaert-Mckey, George D. Weiblen, Vojtech Novotny, Simon T. Segar & Brus Isua
In the fig (Moraceae) and fig‐wasp (Agaonidae) mutualism, scent is believed to be of primary importance in pollinator attraction and maintenance of species specificity. Scent divergence between closely related Ficus species seems sufficient in promoting reproductive isolation through pollinator behaviour, starting the process of speciation. We investigated volatile organic compound (VOC) variation from figs in several Ficus species endemic to Papua New Guinea. Sister species of section Papuacyse and subspecies of Ficus trichocerasa substitute each...

Data from: Soil abiotic variables are more important than Salicaceae phylogeny or habitat specialization in determining soil microbial community structure

Sonya Erlandson, Xiaojing Wei, Jessica Savage, Jeannine Cavender-Bares & Kabir Peay
Predicting the outcome of interspecific interactions is a central goal in ecology. The diverse soil microbes that interact with plants are shaped by different aspects of plant identity, such as phylogenetic history and functional group. Species interactions may also be strongly shaped by abiotic environment, but there is mixed evidence on the relative importance of environment, plant identity, and their interactions in shaping soil microbial communities. Using a multi-factor, split-plot field experiment, we tested how...

Data from: Adaptive radiation along a deeply conserved genetic line of least resistance in Anolis lizards

Joel W. McGlothlin, Megan E. Kobiela, Helen V. Wright, D. Luke Mahler, Jason J. Kolbe, Jonathan B. Losos, & Edmund D. Brodie
On microevolutionary timescales, adaptive evolution depends upon both natural selection and the underlying genetic architecture of traits under selection, which may constrain evolutionary outcomes. Whether such genetic constraints shape phenotypic diversity over macroevolutionary timescales is more controversial, however. One key prediction is that genetic constraints should bias the early stages of species divergence along “genetic lines of least resistance” defined by the genetic (co)variance matrix, G. This bias is expected to erode over time as...

Data from: Environmental filtering and competitive exclusion drive biodiversity-invasibility relationships in shallow lake plant communities

Ranjan Muthukrishnan, Nicole Hansel-Welch & Daniel J. Larkin
1. Understanding the processes that influence the diversity of ecological communities and their susceptibility to invasion by exotic species remains a challenge in ecology. In many systems, a positive relationship between the richness of native species and exotic species has been observed at larger spatial (e.g., regional) scales, while a negative pattern has been observed at local (e.g., plot) scales. These patterns are widely attributed to (1) biotic interactions, particularly biotic resistance, limiting invasions in...

Data from: A novel approach to improve immune effector responses post transplant by restoration of CCL21 expression

Heather E. Stefanski, Leslie Jonart, Emily Goren, James J. Mulé & Bruce R. Blazar
Chemotherapy or chemoradiotherapy conditioning regimens required for bone marrow transplantation (BMT) cause significant morbidity and mortality as a result of insufficient immune surveillance mechanisms leading to increased risks of infection and tumor recurrence. Such conditioning causes host stromal cell injury, impairing restoration of the central (thymus) and peripheral (spleen and lymph node) T cell compartments and slow immune reconstitution. The chemokine, CCL21, produced by host stromal cells, recruits T- and B-cells that provide lymphotoxin mediated...

Prober, Carly J. Stevens, Lauren L. Sullivan, Erica Porter, Emma Ladouceur, Charlotte Allen, Karine H. Moromizato, John W. Morgan, W. Stanley Harpole, Yann Hautier, Nico Eisenhauer, Justin P. Wright, Peter B. Adler, Carlos Alberto Arnillas, Jonathan D. Bakker … & Anita C. Risch
Leaf traits are frequently measured in ecology to provide a ‘common currency’ for predicting how anthropogenic pressures impact ecosystem function. Here, we test whether leaf traits consistently respond to experimental treatments across 27 globally distributed grassland sites across 4 continents. We find that specific leaf area (leaf area per unit mass)—a commonly measured morphological trait inferring shifts between plant growth strategies—did not respond to up to four years of soil nutrient additions. Leaf nitrogen, phosphorus...
