Research ArticleOpen accessIn the abstractASSESSING THE HABITAT SUITABILITY OF TWO DIFFERENT ARTIFICIAL WETLAND HABITATS USING AVIAN COMMUNITY STRUCTURESM. Zakaria, M. N. RajparArtificial wetlands have become highly important habitat for a variety of bird species particularly waterbirds due to loss and degradation of natural wetlands. Avian community structures in two artificial wetland habitats i.e., man-made marsh and lake were investigated to identify the suitability of the habitats for avian species, habitat preference and food resources. Distance sampling point count method detected 35272 … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 24 May 2014 · 7,437 accessesView PDF Cite

Research ArticleOpen accessIn the abstractCONTRIBUTION TO THE CURRENT KNOWLEDGE OF ANT COMMUNITIES (HYMENOPTERA: FORMICIDAE) IN A XEROPHITIC SCRUBLAND OF SOUTHEAST DURANGO, DURANGOMaria P. Gonzalez-Castillo, Gerardo Hinojosa Ontiveros, David Ramírez NoyaIn order to assess the species richness and diversity of ants in a xerophitic scrubland, a total of three areas were monitored in the Southeast of Durango within the municipalities of Nombre de Dios and Durango. Specific richness, relative abundance as well as Shannon’s, Simpson’s and Pielou’s indices of the ant community were obtained. A total of 19 species from … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 13 Feb 2014 · 6,823 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSorption of Phenols: Influence of Groundwater pH and of Soil Organic Carbon ContentSilvia Fiore, Maria Chiara ZanettiProblem statement: Physical and chemical properties of soil, groundwater and pollutants deeply influenced the type and the strength of sorption phenomena involving hydrophobic organic contaminants: Soil fraction of organic carbon (foc) and cation exchange capacity, groundwater pH and pollutants hydrophobicity were with undoubtedly the predominant issues. Approach: In this study an experimental study of the sorption of phenol and 2-nitrophenol … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,010 accessesView PDF Cite
