Decomposition and macronutrient release rates of cereal rye residue in a temperate agroecosystemNARA Subscribed
Cover crops provide important agroecosystem services that include reducing soil erosion and nutrient losses, improving soil structure, and enhancing nutrient cycling. While considerable research has investigated biomass decomposition and nitrogen (N) release from cover crop residues, significant knowledge gaps still exist, particularly related to the amounts and temporal release of other essential macronutrients such as phosph...
Verbal fluency dual-tasks show greater age-related cognitive-motor interference: a meta-analysis of walking performanceNARA Subscribed
A substantial body of literature has examined gait during cognitive dual-tasking in younger and older adults. However, it remains unclear how, and to what extent, different cognitive tasks uniquely influence gait. This meta-analysis quantified age-related differences in gait speed during dual-task walking. Importantly, we examined cognitive task as a potential moderator. We searched Web of Science for studies comparing young a...
For the first time, this study reports the content of tropane alkaloids (TAs) in soybean and soymeal samples sourced from 13 different countries, as well as in various cereals (including corn, millet, wheat, and sorghum) and a product (Super Cereals). The analysis was conducted using a fully validated solid-liquid extraction (SLE) with dilute-and-shoot (DnS) method along with a liquid chromatography-tandem mass spectrometry (L...

Divergence in Regulatory Regions and Gene Duplications May Underlie Chronobiological Adaptation in Desert TortoisesNARA Subscribed
Many cellular processes and organismal behaviours are time‐dependent, and asynchrony of these phenomena can facilitate speciation through reinforcement mechanisms. The Mojave and Sonoran desert tortoises ( Gopherus agassizii and G. morafkai respectively) reside in adjoining deserts with distinct seasonal rainfall patterns and they exhibit asynchronous winter brumation and reproductive behaviours. We used whole genome sequencin...
A transgenic mouse line for assaying tissue-specific changes in endoplasmic reticulum proteostasisNARA Subscribed
Maintenance of calcium homeostasis is important for proper endoplasmic reticulum (ER) function. When cellular stress conditions deplete the high concentration of calcium in the ER, ER-resident proteins are secreted into the extracellular space in a process called exodosis. Monitoring exodosis provides insight into changes in ER homeostasis and proteostasis resulting from cellular stress associated with ER calcium dysregulation...
In situ imaging across ecosystems to resolve the fine‐scale oceanographic drivers of a globally significant planktonic grazerNARA Subscribed
Doliolids are common gelatinous grazers in marine ecosystems around the world and likely influence carbon cycling due to their large population sizes with high growth and excretion rates. Aggregations or blooms of these organisms occur frequently, but they are difficult to measure or predict because doliolids are fragile, under sampled with conventional plankton nets, and can aggregate on fine spatial scales (1–10 m). Moreover...
Implications of barrier ephemerality in geogenomic researchNARA Subscribed
Aim Previous population genetic and phylogeographical studies have shown how generation time and dispersal affect population divergence in the presence of a vicariant barrier. More recently, speciation genomic studies have revealed that selection and recombination can be equally impactful. Here, we test how the interaction of these factors shapes the divergence expected in response to an ephemeral barrier and compare these res...

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...
