Human societies depend on an Earth System that operates within a constrained range of nutrient availability, yet the recent trajectory of terrestrial nitrogen (N) availability is uncertain. Examining patterns of foliar N concentrations ([N]) and isotope ratios (15N) from more than 42,000 samples acquired over 37 years, here we show that foliar [N] declined by 8% and foliar 15N declined by 0.8 – 1.9 ‰. Examining patterns across different climate spaces, foliar 15N declined across...

Light availability and rhizobium variation interactively mediate the outcomes of legume-rhizobium symbiosis

Katy Heath, Justin Podowski, Stephanie Heniff, Christie Klinger, Jennifer Lau, Wendy Yang, Dylan Weese & Patricia Burke
Premise of the study: Nutrients, light, water, and temperature are key factors limiting the growth of individual plants in nature. Mutualistic interactions between plants and microbes often mediate resource limitation for both partners. In the mutualism between legumes and rhizobia, plants provide rhizobia with carbon in exchange for fixed nitrogen. Because partner quality in mutualisms is genotype-dependent, within-species genetic variation is expected to alter the responses of mutualists to changes in the resource environment. Here...

Longitudinal white-matter abnormalities in sports-related concussion: a diffusion MRI study of the NCAA-DoD CARE Consortium

Yu-Chien Wu, Jaroslaw Harezlak, Nahla Elsaid, Zikai Lin, Qiuting Wen, Sourajit Mustafi, Larry Riggen, Kevin Koch, Andrew Nencka, Timothy Meier, Andrew Mayer, Yang Wang, Christopher Giza, John DiFiori, Kevin Guskiewicz, Jason Mihalik, Stephen LaConte, Stefan Duma, Steven Broglio, Andrew Saykin, Michael McCrea & Thomas McAllister
Objective To study longitudinal recovery trajectories of white-matter after sports-related concussion (SRC), we performed diffusion tensor imaging (DTI) on collegiate athletes who sustained SRC. Methods Collegiate athletes (n=219, 82 concussed athletes, 68 contact-sport controls, and 69 non-contact-sport controls) were included from the Concussion Assessment, Research and Education (CARE) Consortium. The participants completed clinical assessments and DTI at four time points: 24-48-hours post-injury, asymptomatic state, seven days following return-to-play, and six-months post-injury. Tract-based spatial statistics were...

Supplementary data for: Primate phylogenomics uncovers multiple rapid radiations and ancient interspecific introgression

Dan Vanderpool, Bin Quang Minh, Robert Lanfear, Daniel Hughes, Shwetha Murali, R. Alan Harris, Muthuswamy Raveendran, Donna M. Muzny, Richard A. Gibbs, Kim C. Worley, Jeffrey Rogers, Matthew W. Hahn, Mark S. Hibbins & Robert J. Williamson
Our understanding of the evolutionary history of primates is undergoing continual revision due to ongoing genome sequencing efforts. Bolstered by growing fossil evidence, these data have led to increased acceptance of once controversial hypotheses regarding phylogenetic relationships, hybridization and introgression, and the biogeographical history of primate groups. Among these findings is a pattern of recent introgression between species within all major primate groups examined to date, though little is known about introgression deeper in time....

Data from: A phylogeny for the Drosophila montium species group: a model clade for comparative analyses

William Conner, Emily Delaney, Michael Bronski, Paul Ginsberg, Timothy Wheeler, Kelly Richardson, Brooke Peckenpaugh, Kevin Kim, Masayoshi Watada, Ary Hoffmann, Michael Eisen, Artyom Kopp, Brandon Cooper & Michael Turelli
The Drosophila montium species group is a clade of 94 named species closely related to the model D. melanogaster species group. The montium species group is distributed over a broad geographic range throughout Asia, Africa, and Australasia. Species of this group possess a wide range of morphologies, mating behaviors, and endosymbiont associations, making this clade useful for comparative analyses. We use genomic data from 42 available species to estimate the phylogeny and relative divergence times...

Genotypic variation in an ecologically important parasite is associated with host species, lake, and spore size

Clara Shaw, Rebecca Bilich, Bruce O'Brien, Carla Cáceres, Spencer Hall, Timothy James & Meghan Duffy
Genetic variation in parasites has important consequences for host-parasite interactions. Prior studies of the ecologically important parasite Metschnikowia bicuspidata have suggested low genetic variation in the species. Here, we collected M. bicuspidata from two host species (Daphnia dentifera and Ceriodaphnia dubia) and two regions (Michigan and Indiana, USA). Within a lake, outbreaks tended to occur in one host species but not the other. Using microsatellite markers, we identified six parasite genotypes grouped within three distinct...

The evolutionary genetics of paternal care: how good genes and extra-pair copulation affect the trade-off between paternal care and mating success

Courtney Fitzpatrick, Colette Ciresi & Michael Wade
We investigate the evolution of a gene for paternal care, with pleiotropic effects on male mating fitness and offspring viability, with and without extra pair copulations (EPCs). We develop a population genetic model to examine how pleiotropic effects of a male mating advantage and paternal care are affected by ‘good genes’ and EPCs. Using this approach, we show that the relative effects of each on fitness do not always predict the evolutionary change. We then...

Information Sharing and Bargaining in Buyer-Seller Networks

Sofia Priazhkina & Frank H. Page
This paper presents a model of strategic buyer-seller networks with information exchange between sellers. Prior to engaging in bargaining with buyers, sellers can share access to buyers for a negotiated transfer. We study how this information exchange affects overall market prices, volumes and welfare, given different initial market conditions and information sharing rules. In markets with homogeneous traders, sharing always increases total trade volume. The market reaches Walrasian trade volume when there are more buyers...

The paper summarizes current literature and research, discusses U.S. government technical report use, and presents data obtained from the Aerospace Knowledge Diffusion Research Project. U.A. aerospace engineers and scientists use technical reports primarily for research and indicate that relevance,...

Is the Licensing of Grey Literature Using the Full Palette of “Contractual” Colors?: A Comparative Analysis of Grey Literature Terms of Use

Tomas Lipinski & Andrea Copeland
This paper reviews a sample of licenses or terms of use governing the use of grey collections. A license is a form of legal permission. It need not be a contract but often is. Some terms of service reviewed do not even provide permission per se but state a list or rules users should follow. From this analysis a list of best licensing practices or checklist of considerations can be offered. Regardless of the specific...

Cangrelor: Safe and Effective for Left Ventricular Assist Device Thrombosis

Roopa Rao, Eve Anderson, Mark Jones, Muhamed Safiia & Maya Guglin
Pump thrombosis is a devastating complication of left ventricular assist device implantation as it increases the risk of mortality and morbidity. Early and effective treatment is important to prevent the progression of the clot and to avoid the surgical need for pump exchange or heart transplant. The current strategies of intensifying anticoagulation therapy are not consistently effective and carry significant bleeding risks. Cangrelor is a new pharmacological agent that has been utilized as an antiplatelet...

Data from: A multi-tissue view on telomere dynamics and postnatal growth

Sarah Wolf & Kimberly Rosvall
Trade-offs between growth and self-maintenance are common in nature, such that early-life effects on growth can generate lasting consequences on survival and longevity. Telomeres – putative biomarkers of self-maintenance – may link early growth with these later phenotypic effects, but evidence for growth-telomere trade-offs is mixed. Null or even positive relationships between growth and telomeres may be driven by heterogeneity in resource availability or invariable allocation towards telomere maintenance within a population. We used nestling...

Observational evidence of herbivore-specific associational effects between neighboring conspecifics in natural, dimorphic populations of Datura wrightii

Jay Goldberg, Sonya Sternlieb, Genevieve Pintel & Lynda Delph
Associational effects – in which the vulnerability of a plant to herbivores is influenced by its neighbors – have been widely implicated in mediating plant-herbivore interactions. Studies of associational effects typically focus on interspecific interactions or pest-crop dynamics. However, associational effects may also be important for species with intraspecific variation in defensive traits. In this study, we observed hundreds of Datura wrightii – which exhibits dimorphism in its trichome phenotype – from over 30 dimorphic...

Supplementary data, code, and information for ‘Interhemispheric antiphasing of neotropical precipitation during the past millennium’ (PNAS, Steinman et al. 2022)

B.A. Steinman, N. Stansall, M.E. Mann, C.A. Cooke, M.B. Abbott, M. Vuille, B.W. Bird, M.S. Lachniet & A. Fernandez
Uncertainty about the influence of anthropogenic radiative forcing on the position and strength of convective rainfall in the Intertropical Convergence Zone (ITCZ) inhibits our ability to project future tropical hydroclimate change in a warmer world. Paleoclimatic and modeling data inform on the timescales and mechanisms of ITCZ variability; yet a comprehensive, long-term perspective remains elusive. Here, we quantify the evolution of neotropical hydroclimate over the pre-industrial past millennium (850 to 1850 CE) using a synthesis...

A Case of HeartMate 3 Outflow Graft Twisting with Extraluminal Thrombosis: Is Computed Tomography Angiography Helpful?

Karim Saleb, Marianna Zagurovskaya, Michael Sekela & Maya Guglin
Twists in the outflow graft of the HeartMateTM 3 device (Abbott) have recently been described as a sporadic, late complication. We present a case with a unique combination of external compression of the HeartMate 3 outflow graft by a surgical scar compounded by thrombus formation in the space between the band relief and the outflow graft with associated twist of the outflow graft and severe flow limitation. Computed tomography angiogram (CTA) of the chest was...

This is our 6th annual literature review on mechanical circulatory support (MCS) devices. Our previous reports for 2014, 2015, 2016, 2017, 2018 were published as open access articles and were well received by the readers (1-5). In this paper, we summarize the most interesting and important, from our standpoint, publications from 2019. As we have done for the past two years, a section on extracorporeal membrane oxygenation (ECMO) is included and primarily addresses new developments...

Linking genetic diversity and species diversity through plant-soil feedback

Lana Bolin & Jennifer Lau
Genetic diversity and species diversity are typically studied in isolation despite theory showing they likely influence one another. Here, we used simplified communities of one or two populations of one or two species to test whether linkages between genetic and species diversity can be mediated by interactions between plants and their soil microbiota, or microbe-mediated plant-soil feedback (PSF). Interspecific PSF promotes the maintenance of species diversity when plants grow better with heterospecific soil microbes than...
