Long-term warming alters carbohydrate degradation potential in temperate forest soils
(American Society for Microbiology, 2016-09-02)
As Earth's climate warms, soil carbon pools and the microbial communities that process them may change, altering the way in which carbon is recycled in soil. In this study, we used a combination of metagenomics and bacterial ...
Correction to “Importance of carbon-nitrogen interactions and ozone on ecosystem hydrology during the 21st century”
(American Geophysical Union, 2009-08-22)
Neuronal calcium sensor-1 enhancement of InsP3 receptor activity is inhibited by therapeutic levels of lithium
(American Society for Clinical Investigation, 2006-06)
Regulation and dysregulation of intracellular calcium (Ca2+) signaling via the inositol 1,4,5-trisphosphate receptor (InsP3R) has been linked to many cellular processes and pathological conditions. In the present study, ...
Regeneration of oral siphon pigment organs in the ascidian Ciona intestinalis
Ascidians have powerful capacities for regeneration but the underlying mechanisms are poorly understood. Here we examine oral siphon regeneration in the solitary ascidian Ciona intestinalis. Following amputation, the ...
Soil hydraulic response to land-use change associated with the recent soybean expansion at the Amazon agricultural frontier
Clearing for large-scale soy production and the displacement of cattle-breeding by soybeans are major features of land-use change in the lowland Amazon that can alter hydrologic properties of soils and the runoff generation ...
N budgets and aquatic uptake in the Ipswich River basin, northeastern Massachusetts
(American Geophysical Union, 2004-11-05)
We calculated N budgets and conducted nutrient uptake experiments to evaluate the fate of N in the aquatic environment of the Ipswich River basin, northeastern Massachusetts. A mass balance indicates that the basin retains ...
An efficient system for selectively altering genetic information within mRNAs
(Oxford University Press, 2016-08-23)
Site-directed RNA editing (SDRE) is a strategy to precisely alter genetic information within mRNAs. By linking the catalytic domain of the RNA editing enzyme ADAR to an antisense guide RNA, specific adenosines can be ...
Characterisation of the subtelomeric regions of Giardia lamblia genome isolate WBC6
Giardia trophozoites are polyploid and have five chromosomes. The chromosome homologues demonstrate considerable size heterogeneity due to variation in the subtelomeric regions. We used clones from the genome project with ...
Baleen whales are not important as prey for killer whales Orcinus orca in high-latitude regions
Certain populations of killer whales Orcinus orca feed primarily or exclusively on marine mammals. However, whether or not baleen whales represent an important prey source for killer whales is debatable. A hypothesis by ...
Phyllosphere microbial communities of a salt-excreting desert tree : geographical location determines population structure
The leaf surfaces of Tamarix, a salt secreting desert tree, harbor a diverse community of microbial epiphytes. This ecosystem presents a unique set of ecological characteristics and imposes a set of extreme stress conditions. ...
