Warmer climates induced by elevated atmospheric CO(2) (eCO(2)) are expected to increase damaging bark beetle activity in pine forests, yet the effect of eCO(2) on resin production--the tree's primary defense against beetle attack--remains largely unknown. Following growth-differentiation balance theory, if extra carbohydrates produced under eCO(2) are not consumed by respiration or growth, resi...

In the United States and the United Kingdom, over the last decade major retail chains have increasingly publicized their efforts to supply sustainably sourced and eco-labelled seafood. Debate exists over the extent of consumer demand for this product. Seafood eco-labels purportedly resolve the information asymmetry between producer and consumer, allowing consumers who care about sustainability ...

We have now enough background in the teaching of eco-design to make some conclusions on practices and evolutions in this area; in France these teachings are very supported by studies of APEDEC (Association of Experts for the Development of Eco-Design) that published in 2006 and 2010 the results of enquiries concerning this subject. Curricula concerning eco-design exist since 1987 but a signific...

We have obtained high-resolution spectra of the extremely metal-poor star CS 22949-037 ( ) [Fe/H] p 3.79 in the region of the ultraviolet NH bands at 3360–3370 Å, which confirm our earlier report that it exhibits extreme nitrogen enhancement. We find . The star is also known to have large relative overabundances, [N/Fe] p 2.3 0.4 of order 0.5–1 dex, of carbon and the a-elements. This abundance ...

Gene rearrangement studies were performed on blood lymphocytes from eight patients with acute Epstein-Barr virus-induced infectious mononucleosis. The diagnosis in each case was based on characteristic clinical, hematologic, and serologic findings. The blood lymphocytes in each patient consisted predominantly of CD8+ T cells. EBV DNA was detected in seven patients by Southern blot analysis (EBV...

Ecological security is an important basis of the entire human security system, the cornerstone for human survival. Knowing the status of ecological security is crucial for making decisions to avoid ecological disaster. Existing research, both the basic research on ecological security mechanism and information service systems, is still primitive in their abilities to resolve eco-security problem...

OBJECTIVES The main goal of the study was to assess possible association between fetal exposure to fine particulate matter (PM2.5) and exhaled carbon monoxide (eCO) measured in non-asthmatic children. MATERIAL AND METHODS The subjects include 118 children taking part in an ongoing population-based birth cohort study in Kraków. Personal samplers of PM2.5 were used to measure fine particle mass...

Deamination of cytosines results in accumulation of uracil residues in DNA, which unless repaired lead to GC-->AT transition mutations. Uracil DNA glyco-sylase excises uracil residues from DNA and initiates the base excision repair pathway to safeguard the genomic integrity. In this study, we have investigated the effect of single-stranded DNA binding proteins (SSBs) from Escherichia coli (Eco ...

A lake ecosystem is continuously exposed to environmental stressors with non-linear interrelationships between abiotic factors and aquatic organisms. Ecosystem health depicts the capacity of system to respond to external perturbations and still maintain structure and function. In this study, we explored the effects of abiotic factors on ecosystem health of Taihu Lake in 2013, China from a syste...
