Research ArticleOpen accessIn the abstractBenthic Macro-Invertebrate Survey in Little Beaver Creek, Kaw Lake WatershedDejene AlemayehuThe Kaw Nation Environmental Department, as part of the water quality monitoring parameters in its non-point source pollution project conducted a benthic macro-inventebrat sampling and taxonomic classification as a stream bioassessment of Little Beaver and Bear Creeks. Little Beaver Creek is located in the tall grass prairie of Kay County, Oklahoma. It is one of the tributary creeks that enter … …American Journal of Environmental Sciences, Vol. 12, Issue 1 · 29 Feb 2016 · 7,361 accessesView PDFCite
Research ArticleOpen accessIn the abstractASSESSING THE EFFECTS OF LOGGING ACTIVITIES ON AVIAN RICHNESS AND DIVERSITY IN DIFFERENT AGED POST-HARVESTED HILL DIPTEROCARP TROPICAL RAINFOREST OF MALAYSIAM. N. Rajpar, M. ZakariaLogging activities have encroached into the hill dipterocarp tropical rainforest area since the lowland dipterocarp forests have decreased in size. Hill dipterocarp tropical rainforest is rich in habitat diversity and provide a variety of resources for avian species such as food, habitat and shelter. Therefore it is important to examine the logging effects of hill dipterocarp rainforest on avian species. … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 15 Jul 2014 · 7,584 accessesView PDFCite
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 PDFCite
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 abstractToward a Hierarchical Bayesian Framework for Modelling the Effect of Regional Diversity on Household ExpenditurePudji Ismartini, Nur Iriawan, Setiawan, Brodjol Sutijo Supri UlamaProblem statement: Household expenditure analysis was highly demanding for government in order to formulate its policy. Since household data was viewed as hierarchical structure with household nested in its regional residence which varies inter region, the contextual welfare analysis was needed. This study proposed to develop a hierarchical model for estimating household expenditure in an attempt to measure the effect … …Journal of Mathematics and Statistics, Vol. 8, Issue 2 · 25 Jun 2012 · 7,309 accessesView PDFCite
Research ArticleOpen accessIn the abstractBacteria on Human SkinRichard W. Hyman, Farbod Babrzadeh, Curtis Palm et al.Problem statement: Human skin is a large (~ 1.75 m2) organ containing a large number of ecologically distinct sites. These sites harbor a variety of distinct microbiomes. One challenge is to define the microbiome at every site. We chose two interesting sites: the base of the Front of the neck and the base of the Back of the neck (the … …Current Research in Microbiology, Vol. 2, Issue 2 · 23 Feb 2012 · 8,204 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Study of Soluble Sulfate Reduction by Bacterial Consortia from Varied Regions of IndiaPoonam Nasipuri, Gauri G. Pandit, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriSoluble sulfate contamination in water is observed due to various industrial activities. Chemical means of reduction are available yet the biological approach is the preferred one. Problem statement: The problem addressed in this study was the isolation of efficient sulfate reducing bacterial consortia for bioremediation of soluble sulfate from mining effluent. Approach: The culture based method using the DSMZ specific … …American Journal of Environmental Sciences, Vol. 6, Issue 2 · 30 Apr 2010 · 7,341 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 abstractGeographic Distribution and Genetic Analysis of Physiological Racesof Setosphaeria turcica in Northern ChinaJingao Dong, Yongshan Fan, Xiumei Gui et al.Five hundreds and forty-six isolates of Setosphaeria turcica, the causal agent of Northern Corn Leaf Blight, were collected in 61 corn-growing locations throughout six provinces of Northern China during 2000-2002, to determine their pathogenicity on two sets of host differentials: OH43/Huangzao4, OH43Ht1Huangzao4Ht1, OH43Ht2/Huangzao4Ht2, OH43Ht3/Huangzao4Ht3 and OH43HtN/Huangzao4HtN. The isolates were grouped into 13 different physiological races (0, 1, 12, 3, 13, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,809 accessesView PDFCite
