Continental Patterns of Phenotypic Variation Along Replicated Urban Gradients: A Mega‐AnalysisNARA Subscribed
Individual variation among and within natural populations can have eco‐evolutionary implications by, for example, affecting species interactions or evolutionary potential. Urban systems present a unique opportunity to evaluate how environmental change shapes variation since urban phenotypic differentiation is widely documented on contemporary timescales. We introduce and test three hypotheses to determine how urbanisation affe...
Low circulating adropin concentrations predict increased risk of cognitive decline in community-dwelling older adultsNARA Subscribed
The secreted peptide adropin is highly expressed in human brain tissues and correlates with RNA and proteomic risk indicators for dementia. Here we report that plasma adropin concentrations predict risk for cognitive decline in the Multidomain Alzheimer Preventive Trial (ClinicalTrials.gov Identifier, NCT00672685; mean age 75.8y, SD = 4.5 years, 60.2% female, n = 452). Cognitive ability was evaluated using a composite cognitiv...
Purpose There is an increasing interest in the use of non-nutritive sweeteners to replace added sugar in food and beverage products for reasons of improving consumer health. Much work has been done to understand safety of sweeteners, but very little on sustainability. To address that gap, this study presents the results of a life cycle assessment (LCA) of production of rebaudioside A 60%, 95% pure (RA60) steviol glycoside mix...
Ecosystems monitoring powered by environmental genomics: A review of current strategies with an implementation roadmapNARA Subscribed
A decade after environmental scientists integrated high‐throughput sequencing technologies in their toolbox, the genomics‐based monitoring of anthropogenic impacts on the biodiversity and functioning of ecosystems is yet to be implemented by regulatory frameworks. Despite the broadly acknowledged potential of environmental genomics to this end, technical limitations and conceptual issues still stand in the way of its broad app...
Considering Resources Beyond Water: Irrigation and Drainage Management in the Context of the Water–Energy–Food NexusNARA Subscribed
While the world is facing unprecedented transitions and threats we need to deeply rethink the relationships between water and energy use, food production, and ecosystem protection. This includes the development and deployment of ambitious, out‐of‐the‐box solutions towards sustainable development. This paper is based upon recent discussions before and during the 2nd World Irrigation Forum in Chiang Mai, Thailand. This paper tak...
The application of irrigation water and nitrogen (N) fertilizer in excess of crop demand reduces profitability and has multiple detrimental impacts on the environment. N dynamics in agro‐ecosystems are extremely complex, and mechanistic crop models are most often required to quantify the impact of improved management practices on reducing fertilizer N losses. In this study, life cycle assessment (LCA) methodology and mechanist...
Variability in smallholders' irrigation water values: Study in North‐West Province, South AfricaNARA Subscribed
Capturing the economic value of water use is an integral part in the design of economic incentives and institutional arrangements that can ensure sustainable, efficient and equitable allocation of water. Irrigation water values of small‐scale irrigators are, however, seldom studied and too little attention is paid to the determinants of the variability of water values. In South Africa issues like the call for more efficient wa...
