Evaluating a Tri-Institutional Cancer Research Capacity-Building Program for Early-Stage InvestigatorsNARA Subscribed
The Comprehensive Partnerships to Advance Cancer Health Equity (CPACHE) initiative of the National Cancer Institute (NCI) supports long-standing collaborations between an under-resourced institution and NCI-designated Cancer Centers to strengthen cancer research workforce and advance cancer research capacity. One of the longest continuously funded CPACHE programs is the Morehouse School of Medicine/Tuskegee University/Universi...
Dominance and rarity in tree communities across the globe: Patterns, predictors and threatsNARA Subscribed
Aim Ecological and anthropogenic factors shift the abundances of dominant and rare tree species within local forest communities, thus affecting species composition and ecosystem functioning. To inform forest and conservation management it is important to understand the drivers of dominance and rarity in local tree communities. We answer the following research questions: (1) What are the patterns of dominance and rarity in tree...
In a nutshell: almond hull and shell organic matter amendments increase soil and tree potassium statusNARA Subscribed
Background Crop residues used as organic matter amendments have been shown to release potassium (K) into the soil, promoting K cycling in agronomic systems. Orchard field trials are needed to evaluate K dynamics under almond hull and shell amendments, which contain high K concentrations. Methods Three field trials in commercial almond orchards were conducted to assess the effects of surface-applied almond hull and shell amendm...
Wood in the deep sea serves as a substantial food source in an otherwise barren environment, forming specialized, endemic, and diverse community assemblages. This biodiversity reliance on a terrestrial source creates a linkage by which anthropogenic impacts on land can alter the deep oceans. Knowledge of the alpha‐ or beta‐diversity of entire wood‐fall communities, and wooden drivers of each would elucidate the terrestrial and...
Fragmentation effects on an endangered species across a gradient from the interior to edge of its rangeNARA Subscribed
Understanding how habitat fragmentation affects individual species is complicated by challenges associated with quantifying species‐specific habitat and spatial variability in fragmentation effects within a species’ range. We aggregated a 29‐year breeding survey data set for the endangered marbled murrelet ( Brachyramphus marmoratus ) from >42,000 forest sites throughout the Pacific Northwest (Oregon, Washington, and northern...
Common, low-frequency, rare, and ultra-rare coding variants contribute to COVID-19 severityNARA Subscribed
The combined impact of common and rare exonic variants in COVID-19 host genetics is currently insufficiently understood. Here, common and rare variants from whole-exome sequencing data of about 4000 SARS-CoV-2-positive individuals were used to define an interpretable machine-learning model for predicting COVID-19 severity. First, variants were converted into separate sets of Boolean features, depending on the absence or the pr...
Testing a global standard for quantifying species recovery and assessing conservation impactNARA Subscribed
Recognizing the imperative to evaluate species recovery and conservation impact, in 2012 the International Union for Conservation of Nature (IUCN) called for development of a “Green List of Species” (now the IUCN Green Status of Species). A draft Green Status framework for assessing species’ progress toward recovery, published in 2018, proposed 2 separate but interlinked components: a standardized method (i.e., measurement aga...
Stroke Induces Prolonged Changes in Lipid Metabolism, the Liver and Body Composition in MiceNARA Subscribed
During recovery, stroke patients are at risk of developing long-term complications that impact quality of life, including changes in body weight and composition, depression and anxiety, as well as an increased risk of subsequent vascular events. The aetiologies and time-course of these post-stroke complications have not been extensively studied and are poorly understood. Therefore, we assessed long-term changes in body composi...
