  1. Abstract. Despite the centrality of the water balance equation to hydrology and waterresources, in 2018 we still lack adequate empirical observations ofconsumptive use of water by humans and their economy. It is therefore worthconsidering what we can do with the withdrawal-based water use data wealready possess, and what future water census measurements would be requiredto more accurately quantify consumptive use for the most common mesoscale usecases. The limitations of the currently applied simple net consumptive use(SNCU) assumptions are discussed for several common use cases. Fortunately,several applied water management, economics, and policy questions can besufficiently addressed using currently available withdrawal numbers in placeof water consumption numbers. This discussion clarifies the broadrequirements for an improved “stock and flow” census-scale data model forconsumptive water use. While we are waiting for the eventual arrival of amore sophisticated water census, the withdrawal data we already possess aresufficient for some of our most important scientific and applied purposes.

  2. Abstract

    Although covalent nucleotide modifications were first identified on the bases of transfer RNAs (tRNAs) and ribosomal RNAs (rRNAs), a number of these epitranscriptome marks have also been found to occur on the bases of messenger RNAs (mRNAs). These covalent mRNA features have been demonstrated to have various and significant effects on the processing (e.g. splicing, polyadenylation, etc.) and functionality (e.g. translation, transport, etc.) of these protein-encoding molecules. Here, we focus our attention on the current understanding of the collection of covalent nucleotide modifications known to occur on mRNAs in plants, how they are detected and studied, and the most outstanding future questions of each of these important epitranscriptomic regulatory signals.
