Vegetation cover, low-relief topography, and sparse bedrock exposure in western Kentucky hinder accurate delineation of stratigraphic boundaries within mixed siliciclastic–carbonate successions, limiting conventional field-based geologic mapping. To address this challenge, we present a new 1:10,000-scale geologic map of the McDaniels Quadrangle that integrates 1.5 m LiDAR-derived topography, Sentinel-2 multispectral imagery, r...

[ 11 C]COU is a trapped metabolite radiotracer for in vivo analysis of Monoamine Oxidase B activity using positron emission tomography (PET) imaging. [ 11 C]COU has the potential to quantify astrocytosis in the early stages of Alzheimer’s disease, providing an earlier marker of disease than currently available for staging disease progression. Prior preclinical studies have demonstrated the efficacy of this radiotracer in precl...

Increasing frequency of droughts and wildfire are sparking concerns that these compounded disturbance events are pushing forested ecosystems beyond recovery. An improved understanding of how compounded events affect tree physiology and mortality is needed given the reliance of fire management planning on accurate estimates of postfire tree mortality. In this study, we use a toxicological dose-response approach to quantify the...

This study investigated the relationship between the size, condition, year class, family, and sexual maturity of Atlantic salmon ( Salmo salar ) using data collected in an aquaculture selective breeding programme. Males that were sexually mature at 2 years of age (maiden spawn) have, on average, greater fork length and condition factor ( K ) at 1 year of age than their immature counterparts. For every 10‐mm increase in fork le...

Fire–vegetation feedbacks potentially maintain global savanna and forest distributions. Accordingly, vegetation in savanna and forest ecosystems should have differential responses to fire, but fire response data for herbaceous vegetation have yet to be synthesized across biomes. Here, we examined herbaceous vegetation responses to experimental fire at 30 sites spanning four continents. Across a variety of metrics, herbaceous v...
