Approximately 70,150 dry Mg of biosolids from over 450 wastewater treatment facilities are applied to the semi-arid rangelands of Colorado every year. Research on semi-arid grassland responses to biosolids has become vital to better understand ecosystem dynamics and develop effective biosolids management strategies. The objectives of this study were to determine the long-term (w12 years) effect...
Plant and microbial community composition in connection with soil chemistry determines soil nutrient cycling. The study aimed at demonstrating links between plant and microbial communities and soil chemistry occurring among and within four sites: two pine forests with contrasting soil pH and two grasslands of dissimilar soil chemistry and vegetation. Soil was characterized by C and N content, p...
Variability in essential oil chemistry and plant morphology within aLeptospermum scopariumpopulation
Little is currently known about preservation of plant DNA in lake sediments. Most prior information originates from laboratory experiments while systematic field-based studies are still lacking. Here, we used the “g” and “h” universal primers for P6 loop region chloroplast trnL (UAA) intron to amplify 219 surface sediments China Siberia. We introduce (i) percentage sequence counts with best ide...
Green chemistry is an alternative route of which has overcome the limitations of other chemical methods. Nanocrystalline zinc oxide (NC-ZnO) with different structures have been grown on quartz plates by spin coating method by the use of plant extracts of Citrus aurantifolia which can be a cost effective and eco-friendly approach.. The present exploration describes the synthesis and characteriza...
Fungal endophytes inhabit healthy tissues of all terrestrial plant taxa studied to date and are diverse and abundant in leaves of tropical woody angiosperms. Studies have demonstrated that plant location and leaf age influence density of endophyte infection in leaves of tropical forest trees. However, ecological factors underlying these observations have not been explored in detail. Here, we es...
Elevated levels of CO2 affect plant growth and leaf chemistry, which in turn can alter host plant suitability for insect herbivores. We examined the suitability of foliage from trees grown from seedlings since 1997 at Aspen FACE as diet for the gypsy moth (Lymantria dispar L.) Lepidoptera: Lymantriidae: paper birch (Betula papyrifera Marshall) in 2004-2005, and trembling aspen (Populus tremuloi...
The environmental, social and economical reasons indicate that the conventional agriculture constitute a continuous pressure contributing to the progressive worsening of environmental conditions, especially by an increasing apply high level of inputs. In this matter, the increasing use of saline irrigation water is one of the main factors resulting in salt accumulation in the plant rhizosp...
