Given the forestry, ecological and economic value of forests with participation Fraxinus excelsior taking into account intensive deterioration their phytosanitary status in modern conditions, a comprehensive study symptoms, causes, pathogenesis ash tuberculosis further development effective protection measures, including using biological products based on Bacillus sp. other myco- microorganisms...

Trees provide a wide variety of ecosystem services to society and form the character environment landscape. The analyses tree populations their resistance changing conditions related climate change typically focus on urban communities or forest trees. Similar studies non-forest trees in open landscape are largely missing; even evidence species abundance distribution is sporadic. article aims ex...

Heavy metal pollutionis one of the largest problems in the Environment and human being. In industrial and urban areas trees can give better quantifications for pollutant concentrations and atmospheric deposition than non-biological samples. In order to know ability of Fraxinus excelsior­ (Ash tree) to reduce the concentrations of heavy metals and compared with the concentration of thes...

BACKGROUND Evidence-based medicine (EBM) has been included in the Accreditation Council for Graduate Medical Education (ACGME) and the American Board of Emergency Medicine (ABEM) milestones project as a required component during emergency medicine (EM) residency training. Milestone Level One states that graduating medical students must be able to "describe basic principles of EBM." OBJECTIVE ...

Quantifying carbon in agroforestry trees requires biomass equations that capture the growth differences (e.g., tree specific gravity and architecture) created in the more open canopies of agroforestry plantings compared with those generally encountered in forests. Whereas forest-derived equations are available, equations for open-grown trees are not. Data from destructively sampled open-grown t...
