Effects of delta-9 tetrahydrocannabinol and cannabidiol on cognitive outcomes following acute use of cannabis for chronic painNARA Subscribed
Rationale An estimated two-thirds of medical cannabis users in the United States are motivated by chronic pain, but clinical guidance remains guarded as to whether the potential benefit of cannabinoids for pain outweighs potential risks, such as effects on cognition. Objectives In a study where participants experienced benefits of cannabinoids for pain and tension, we evaluated cannabis effects on executive function, processin...
Motivation The database initiated by the Mountain Invasion Research Network (MIREN) is one of the few globally implemented standardized vegetation surveys in mountains. The focus is on collecting plant species occurrences at 5‐year intervals along and adjacent to mountain roads spanning elevational gradients, with the goal of providing critical information about the ongoing spread of non‐native plants and the potential impacts...
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened Species by assessing the vulnerability of 256 marine megafauna species to 23 at‐sea threat...
Background Plants are exposed to diverse abiotic and biotic stressors during their lifecycle, including flooding and insect herbivory. To mitigate stressors, plants utilize several “cry for help” strategies, including producing volatile organic compounds (VOCs) aboveground and modifying microbial communities belowground. Although we have built strong understanding of plants “cry for help” strategies to individually occurring s...
Genetic variation in Zea mays influences microbial nitrification and denitrification in conventional agroecosystemsNARA Subscribed
Background and Aims Nitrogenous fertilizers provide a short-lived benefit to crops in agroecosystems, but stimulate nitrification and denitrification, processes that result in nitrate pollution, N 2 O production, and reduced soil fertility. Recent advances in plant microbiome science suggest that genetic variation in plants can modulate the composition and activity of rhizosphere N-cycling microorganisms. Here we attempted to...
Soil microbial community response to ectomycorrhizal dominance in diverse neotropical montane forestsNARA Subscribed
Ectomycorrhizal (EM) associations can promote the dominance of tree species in otherwise diverse tropical forests. These EM associations between trees and their fungal mutualists have important consequences for soil organic matter cycling, yet the influence of these EM-associated effects on surrounding microbial communities is not well known, particularly in neotropical forests. We examined fungal and prokaryotic community com...
Summary Microbial populations provide nitrogen cycling ecosystem services at the nexus of agriculture, environmental quality and climate change. Denitrification, in particular, impacts socio‐environmental systems in both positive and negative ways, through reduction of aquatic and atmospheric nitrogen pollution, but also reduction of soil fertility and production of greenhouse gases. However, denitrification rates are quite va...
Elevated carbon dioxide accelerates the spatial turnover of soil microbial communitiesNARA Subscribed
Although elevated CO 2 ( eCO 2 ) significantly affects the α ‐diversity, composition, function, interaction and dynamics of soil microbial communities at the local scale, little is known about eCO 2 impacts on the geographic distribution of micro‐organisms regionally or globally. Here, we examined the β ‐diversity of 110 soil microbial communities across six free air CO 2 enrichment ( FACE ) experimental sites using a high‐thr...
