This study was conducted at a bottomland hardwood site with heavy textured soil in Akyazi, Turkey to determine the effect of initial spacing (3.0 x 3.0, 3.0 x 2.0, 2.5 x 1.6 and 2.5 x 1.2 m) and post-planting treatments (untreated check, moving, hoeing, disking, and hoeing plus disking) on early survival and growth of Fraxinus angustifolia Vahl. One-year old bare-root seedlings (70 +/- 5 cm in ...
In the present study, cadmium (Cd) accumulation capabilities of aquatic macrophytes Ceratophyllum demersum, Bacopa monnieri and Rotala rotundifolia were determined after treating both individual and triple macrophytes. The macrophytes were treated with Cd at 0, 0.1, 1 and 10 mg/L concentrations in a controlled chamber for 12-days. Cadmium accumulations increased with increasing Cd concentratio...
Recent phylogenetic works have begun to address long-standing questions regarding the systematics of Campanula (Campanulaceae). Yet, aspects of the evolutionary history, particularly in northwestern North America, remain unresolved. Thus, our primary goal in this study was to infer the phylogenetic positions of northwestern Campanula species within the greater Campanuloideae tree. We combined n...

Quantitative data of community structure and the current status of ecologically and economically important Drosera burmanii Vahl. Populations were gathered at Tripura, India, from two different stands, Suryamaninagar (Site i) and Ishanchandranagar (Site ii). The area of occupancy of Drosera in both sites was measured. A total of 31 species (26 genera of 18 families) were recorded to be associat...
