Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds (open access)

Prioritizing riparian corridors for ecosystem restoration in urbanizing watersheds

This article explores restoration, rather than protection, being the basis for developing a watershed level strategy for improving water quality in urbanizing watersheds.This study uses a geographical information system (GIS) approach that utilizes riparian characteristics extracted from 40-meter wide corridors centered on streams and rivers. The model was applied to 90 sub-watersheds in the watershed of an important drinking water reservoir in north central Texas, USA.

Re-evaluation of rate constants for the reaction N2H4 (+ M) ⇄ NH2 + NH2 (+ M) (open access)

Re-evaluation of rate constants for the reaction N2H4 (+ M) ⇄ NH2 + NH2 (+ M)

Article describes how rate constants for the dissociation/recombination reaction N2H4 (+ M) ⇄ NH2 + NH2 (+ M) are determined by a combination of quantum-chemical calculations and statistical unimolecular rate theory. Implications of the present re-evaluated rate constants for the modeling of high temperature ammonia oxidation kinetics are discussed, showing an only small influence of their precise values on the overall properties of the process.

Homologues and homology and their related terms in phylogenetic systematics (open access)

Homologues and homology and their related terms in phylogenetic systematics

Article describes how, in the field of phylogenetic systematics, the terms homology and homologue and their relationship to cladistic terms such as character, character state, synapomorphy and symplesiomorphy, as well as their relationships to each other, have been and are still discussed frequently. A recent re-emergence of concepts of homology/homologue free of any reference to explanatory hypotheses prompted the authors to explore these concepts and their relationships to each other as well as to the concept of morpheme, as introduced recently.

Modulating Uranium Extraction Performance of Multivariate Covalent Organic Frameworks through Donor–Acceptor Linkers and Amidoxime Nanotraps (open access)

Modulating Uranium Extraction Performance of Multivariate Covalent Organic Frameworks through Donor–Acceptor Linkers and Amidoxime Nanotraps

Article presents a COF (covalent organic framework)-based adsorption-photocatalysis strategy for selective removal of uranyl from seawater in the absence of sacrificial reagents. This work shows that multivariate COF adsorption-photocatalysts can be rationally engineered to work efficiently and stably without sacrificial electron donors, thus opening the pathway for the economic and efficient extraction of uranium from the earth’s oceans.

Visualization of Lipid Droplet Composition by Direct Organelle Mass Spectrometry (open access)

Visualization of Lipid Droplet Composition by Direct Organelle Mass Spectrometry

Article reporting an approach that combines the visualization of individual lipid droplets (LDs), microphase extraction of lipid components from droplets, and the direct identification of lipid composition by nanospray mass spectrometry, even to the level of a single LD. The triacylglycerol (TAG) composition of LDs from several plant sources (mature cotton (Gossypium hirsutum) embryos, roots of cotton seedlings, and Arabidopsis thaliana seeds and leaves) were examined by direct organelle mass spectrometry and revealed the heterogeneity of LDs derived from different plant tissue sources.

Mutations in Arabidopsis Fatty Acid Amide Hydrolase Reveal That Catalytic Activity Influences Growth but Not Sensitivity to Abscisic Acid or Pathogens (open access)

Mutations in Arabidopsis Fatty Acid Amide Hydrolase Reveal That Catalytic Activity Influences Growth but Not Sensitivity to Abscisic Acid or Pathogens

Article showing that the enhanced growth and NAE tolerance of the AtFAAH overexpressing seedlings depends on the catalytic activity of AtFAAH, hypersensitivity to ABA and hypersusceptibility to nonhost pathogens are independent of its enzymatic activity. Findings suggest that the AtFAAH influences plant growth and interacts with ABA signaling and plant defense through distinctly different mechanisms.

Sub-Antarctic Freshwater Invertebrate Thermal Tolerances: An Assessment of Critical Thermal Limits and Behavioral Responses (open access)

Sub-Antarctic Freshwater Invertebrate Thermal Tolerances: An Assessment of Critical Thermal Limits and Behavioral Responses

Describes study which assessed the upper (CTmax) and lower (CTmin) thermal limits of three freshwater macroinvertebrate taxa with restricted low elevation distribution (20 m a.s.l.) and three taxa restricted to upper elevations (480 and 700 m a.s.l.) in the Magellanic sub-Antarctic ecoregion of southern Chile, and argues that their low tolerance to temperature increase can make them useful as indicators of thermal alteration in their habitats.
