TL;DR: The OH stretching vibrational spectra of size-selected H+(H2O)n clusters through the region of the pronounced “magic number” at n = 21 in the cluster distribution provide direct evidence that, for the magic number cluster, all the dangling OH groups arise from water molecules in similar binding sites.
Abstract: We report the OH stretching vibrational spectra of size-selected H+(H2O)n clusters through the region of the pronounced “magic number” at n = 21 in the cluster distribution. Sharp features are observed in the spectra and assigned to excitation of the dangling OH groups throughout the size range 6 ≤ n ≤ 27. A multiplet of such bands appears at small cluster sizes. This pattern simplifies to a doublet at n = 11, with the doublet persisting up to n = 20, but then collapsing to a single line in the n = 21 and n = 22 clusters and reemerging at n = 23. This spectral simplification provides direct evidence that, for the magic number cluster, all the dangling OH groups arise from water molecules in similar binding sites.

TL;DR: The combination of individual longevity, high intra-population genetic diversity and the potential for high rates of pollen flow should make tree species especially resistant to extinction and the loss of genetic diversity during changing environmental conditions.

TL;DR: Results support many of the criticisms of work-family research and suggest that scholars publishing WF research in industrial-organizational psychology and organizational behavior journals could make greater use of longitudinal and experimental research designs, gather more multisource data, and move beyond the individual level of analysis.
Abstract: A methodological review was conducted of work-family (WF) research published in industrial-organizational psychology and organizational behavior journals over a period of 24 years (1980-2003). Content analysis was conducted on 225 individual studies published in 210 articles to categorize methodological features, including the research design, sources of data used, data analysis techniques, reliability and validity of measures used, and sociodemographic characteristics of the samples. Results support many of the criticisms of WF research and suggest that scholars publishing WF research in industrial-organizational psychology and organizational behavior journals could make greater use of longitudinal and experimental research designs, gather more multisource data, and move beyond the individual level of analysis. Adopting more diverse conceptualizations of family, including a greater proportion of racial and ethnic minorities, and studying workers in occupations other than managerial or professional positions also appear warranted. Finally, methodological trends varied across specific WF content areas, which suggests that distinct methodologies might be useful to advance knowledge of specific WF topics.

TL;DR: A genetics-based phytoremediation strategy for arsenic in which the oxyanion arsenate is transported aboveground, reduced to arsenite, and sequestered in thiol–peptide complexes is developed, applicable to a wide variety of plant species.
Abstract: We have developed a genetics-based phytoremediation strategy for arsenic in which the oxyanion arsenate is transported aboveground, reduced to arsenite, and sequestered in thiol-peptide complexes. The Escherichia coli arsC gene encodes arsenate reductase (ArsC), which catalyzes the glutathione (GSH)-coupled electrochemical reduction of arsenate to the more toxic arsenite. Arabidopsis thaliana plants transformed with the arsC gene expressed from a light-induced soybean rubisco promoter (SRS1p) strongly express ArsC protein in leaves, but not roots, and were consequently hypersensitive to arsenate. Arabidopsis plants expressing the E. coli gene encoding gamma-glutamylcysteine synthetase (gamma-ECS) from a strong constitutive actin promoter (ACT2p) were moderately tolerant to arsenic compared with wild type. However, plants expressing SRS1p/ArsC and ACT2p/gamma-ECS together showed substantially greater arsenic tolerance than gamma-ECS or wild-type plants. When grown on arsenic, these plants accumulated 4- to 17-fold greater fresh shoot weight and accumulated 2- to 3-fold more arsenic per gram of tissue than wild type or plants expressing gamma-ECS or ArsC alone. This arsenic remediation strategy should be applicable to a wide variety of plant species.

TL;DR: In this paper, the importance of terrestrial detrital inputs to secondary productivity of a headwater stream was examined, and the authors used randomized intervention analysis (RIA) to test the null hypotheses that no change in abundance or biomass of functional feeding groups or specific taxa occurred in the treatment stream relative to the reference stream.
Abstract: We examined the importance of terrestrial detrital inputs to secondary productivity of a headwater stream. Following a year of pretreatment studies on two headwater streams, we excluded terrestrial litter inputs (=treatment) to one stream while using the other as a reference. We excluded litter for 3 yr followed by 1 yr of small woody debris (≤10 cm diameter) removal and litter exclusion. Monthly benthic samples were collected from dominant mixed substrate (cobble, pebble, and sand-silt) as well as from moss-covered bedrock outcrop substrates. We used randomized intervention analysis (RIA) to test the null hypotheses that no change in abundance or biomass of functional feeding groups or specific taxa occurred in the treatment stream relative to the reference stream. Benthic organic matter was significantly lower in mixed substrate habitats of the treatment stream; however, small woody debris did not show a significant reduction prior to manual removal during year 4. At the end of the treatment period, tot...
