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 PDFCite
Research ArticleOpen accessIn the abstractMacroinvertebrate Communities Differences on Riverine Parts and Reservoirs of Zarrineh RiverR. Ahmadi, A. Aliyev, M. Seidgar et al.This study was conducted to identify present macro invertebrate’s fauna in reverine and reservoir parts of the Zarrinehrood River for fisheries purposes. The abundance and species composition of macro invertebrate were analyzed and compared in various parts of the Zarrinehrood River (west Azerbaijan, Iran) during November 2008-February 2009 to evaluate the rivers benthic fauna as a resource of fish and … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 24 Feb 2012 · 8,153 accessesView PDFCite
Research ArticleOpen accessIn the abstractBirds as a Tool for Island Habitat Conservation and ManagementPedro Rodrigues, Regina Tristao da CunhaProblem statement: The Azores is a archipelago of nine volcanic islands, situated in the middle of the North Atlantic Ocean. Oceanic islands are known hotspots of biodiversity and the Azores, although relatively young (0.3-13 MA), conform to this general pattern. The local avifauna amount to 37 birding species, with two endemic species and 11 endemic subspecies. With an estimated population … …American Journal of Environmental Sciences, Vol. 8, Issue 1 · 20 Jan 2012 · 8,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnt Diversity in a Sugarcane Culture without the Use of Straw Burning in Southeast, Sao Paulo, BrazilDébora Rodrigues De Souza, Erich Stingel, Luiz Carlos de Almeida et al.Problem statement: One of the current requirements of agroecosystem management is the maintenance of biodiversity. Manual sugarcane harvesting with the previous burning of straw has been gradually replaced by mechanical harvesting in Brazil. However, the diversity of Formicidae, which can be a natural pest controller, has not been studied in this new system yet. Approach: This study was carried out … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 8,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Review: Potentiality of Zooplankton as BioindicatorZannatul Ferdous, A. K.M MuktadirProblem statement: This review tended to summarize some recent research on zooplankton as bioindicator in India and some other countries of the world. Approach: These researches were mainly on fresh water bodies. Results: Qualitative as well as quantitative analysis were done by Shannon diversity index (H'), Evenness index (J), Species Richness index (S) and Saprobic index. In most of the … …American Journal of Applied Sciences, Vol. 6, Issue 10 · 31 Oct 2009 · 9,043 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Role of Pioneer Vegetations in Accelerating The Process of Natural SuccessionNormaniza Osman, Faisal Haji Ali, Syed Shahar BarakbahProblem Statement: Even though bioengineering technique has been regarded as one way to alleviate landslide and erosion problems, this process of revegetation is severely time consuming as the process of plant succession of the slopes may take decades or even hundreds of years. Approach: However, the process can be tremendously hastened by planting the right suitable pioneer species on the … …American Journal of Environmental Sciences, Vol. 5, Issue 1 · 28 Feb 2009 · 7,429 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of The Biological Integrity of The Native Vegetative Community In A Surface Flow Constructed Wetland Treating Industrial Park ContaminantsC. C. Galbrand, A. M. Snow, Abdel E. Ghaly, R. CôtéA study was conducted to evaluate the biological integrity of a constructed wetland receiving landfill leachate and stormwater runoff from the Burnside Industrial Park, Dartmouth, Nova Scotia. The biological integrity of the constructed wetland was tested in the second growing season using vegetative community monitoring. The metrics analyzed were species diversity, species heterogeneity (dominance) and exotic/invasive species abundance. There was … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 7,002 accessesView PDFCite
