Genome‐wide associations of leaf spectral variation in MAGIC lines of Nicotiana attenuataNARA Subscribed
The application of in‐field and aerial spectroscopy to assess functional and phylogenetic variation in plants has led to novel ecological insights and supports global assessments of plant biodiversity. Understanding how plant genetic variation influences reflectance spectra will help harness this potential for biodiversity monitoring and improve understanding of why plants differ in functional responses to environmental change...
Carbon fluxes in two temperate ponds are mediated by stratification and primary producersNARA Subscribed
Ponds influence global carbon (C) cycling due to high rates of organic C (OC) burial and carbon dioxide (CO 2 ) and methane (CH 4 ) emissions. Here, we quantified OC burial rates and CO 2 and CH 4 concentrations and fluxes in two ponds that were similar in size and gross primary production, but differed in depth and dominant primary producers. The deeper (3.9 m) Texas Hollow Pond was phytoplankton dominated with stronger and l...
Influence of real-world cue exposure and mood states on drinking: testing neurobiological models of alcohol use disorderNARA Subscribed
Rationale Two prominent neurobiological models of addiction, the allostatic and incentive-sensitization models, have guided clinical research on alcohol use disorder (AUD). While these models are often viewed in isolation, it is plausible these theories are complimentary. Objectives Use naturalistic, daily diary reports to determine whether positive and negative mood states influence alcohol cue sensitivity in a clinical sampl...
Leveraging meta-regression to test if medication effects on cue-induced craving are associated with clinical efficacyNARA Subscribed
Rationale The alcohol cue exposure paradigm is a common method for evaluating new treatments for alcohol use disorder (AUD); however, it is unclear if medication-related reductions in cue-induced craving in the human laboratory can predict the clinical success of those medications in reducing alcohol consumption during clinical trials. Objectives To use a novel meta-analytic approach to test whether medication effect sizes on...
Are medication effects on subjective response to alcohol and cue-induced craving associated? A meta regression studyNARA Subscribed
Rationale Alcohol administration and cue-reactivity paradigms are frequently used to screen for the initial efficacy of medications for alcohol use disorder (AUD). While medication effects on the primary outcomes for these paradigms are assumed to be qualitatively related, there is a critical lack of quantitative evidence to support this hypothesis. Objectives The study aims to test the relationship between medication effect s...
Spatial and temporal variability in summertime dissolved carbon dioxide and methane in temperate ponds and shallow lakesNARA Subscribed
Small waterbodies have potentially high greenhouse gas emissions relative to their small footprint on the landscape, although there is high uncertainty in model estimates. Scaling their carbon dioxide (CO 2 ) and methane (CH 4 ) exchange with the atmosphere remains challenging due to an incomplete understanding and characterization of spatial and temporal variability in CO 2 and CH 4 . Here, we measured partial pressures of CO...
Endosymbiont‐induced cytoplasmic incompatibility (CI) may play an important role in arthropod speciation. However, whether CI consistently becomes associated or coupled with other host‐related forms of reproductive isolation (RI) to impede the transfer of endosymbionts between hybridizing populations and further the divergence process remains an open question. Here, we show that varying degrees of pre‐ and postmating RI exist...
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...
Surface-canopy forming kelps provide the foundation for ecosystems that are ecologically, culturally, and economically important. However, these kelp forests are naturally dynamic systems that are also threatened by a range of global and local pressures. As a result, there is a need for tools that enable managers to reliably track changes in their distribution, abundance, and health in a timely manner. Remote sensing data avai...
