Domestication today is a self-conscious enterprise of advanced science and global-scale effort, an applied research endeavor comprised of thousands of highly trained and well-supported international specialists. Major research centers like the International Potato Center in Lima, Peru support ongoing efforts to further the domestication of useful species; seed banks have been established in many countries to…

Carbohydrate or sugar resources, predominantly from extrafloral nectaries – vegetative structures that secrete nectar– and hemipteran honeydew, are one of the most widely used food resources by ants and parasitoid wasps . These stable and highquality plant and animal exudates represent an important component of ant diets . Sugar resources can drive the formation of…

Precipitation recorded in the 2021-2022 season was 635.4mm, and while this was the wettest among the study years, precipitation remained below the long-term average precipitation for the region. The hyper-arid conditions across the three study years highlighted the necessity of irrigation water in production regions that were historically dry-farmed and are now affected by substantial…

A changing climate is threatening the sustainability of the vineyard itself as well as the quality of its outputs. More frequent heat waves result in a dissociation of primary and secondary metabolism in the grape berries due to reduced biosynthesis and thermal degradation of secondary metabolites. This decoupling between primary and secondary metabolites led to…

Consequently, a greater amount of unabsorbed BAs remain in the intestines where they can be transformed by intestinal microbes into toxic, hydrophobic BAs. Indeed, ASBT KO mice had a 10 – to 20-fold increase in fecal BA excretion and an 80% reduction in BA pool size compared to WT mice despite up-regulated BA synthesis. Paralleling its…

Our study elucidates the differences in varieties’ sensitivities to climate and clusters the response by region of origin to explore the plastic phenotypic responses of present-day cultivars. Using published genetic data on thousands of varieties, we were able to incorporate geographic sub-regions of origin into our model comparison and produce predictions on timing for the…

The transcript abundance of VviOMT1 was higher in the pulp than the skin . In addition, the transcript abundance of VviOMT1 decreased significantly with °Brix level in the pulp. There were no significant differences in the trancript abundance in the skin or pulp for VviOMT2, VviOMT3 or VviOMT4 . There was a high correlation of the…

The resulting Coulomb blockade phenomenon gives nanoSQUID sensors a very slight electric field sensitivity. Gating exfoliated heterostructures tends to produce large electric fields, and these are detectable as variations in the current through the nanoSQUID as a result of Coulomb blockade in parallel with the SQUID on the tip. Droplets functioning as quantum dots and…

Layer realignments are close analogues of magnetic phase transitions we have already discussed, and they support magnetic hysteresis as well. We will be studying the magnetic phase transition highlighted in yellow with the nanoSQUID microscope. An optical microscope image of a large four-layer CrI3 sample and a much smaller CrI3 monolayer is shown in Fig.…

This example highlights the need for locally and regionally specific research into the social–ecological causes and consequences of changing coffee production patterns.In addition to global and regional shifts in coffee cultivation, within-farm vegetation management has changed dramatically across centuries of coffee production. Farm-level coffee management involves distinctions in elevation, sun exposure, soil conditions, the density…
