with the aim of identifying the rotifera fauna of kepektas dam lake, samples were collectedmonthly between january-december 2005. in total 11 rotifer species were identified. as a species-wisepercentage, kellicttia longispina had the highest level with 57%. when the annual abundance of species wastaken into consideration polyarthra vulgaris, colurella uncinata, asplanchna priodonta and keratell...

we studied litterfall dynamic of tree plantations in dez river floodplain, at 14 to 15 years old. the plantations consist of populus euphratica oliv., eucalyptus camaldulensis dehnh., e. microtheca f. muell, acacia farnesiana (l.) willd., a. salicina lindl., a. saligna (labill.) h. wendl., a. stenophylla benth. and dalbergia sissoo roxb. litterfall was different between the tree species, and le...

a long-term study was conducted between 1985 and 2003 on rehabilitation trials at sishen ironore mine, south africa, to identify grass species that would survive in the artificial growth medium appliedto the sites, and to determine the most suitable medium for sustainable vegetation growth. vegetationestablishment was tested at slopes of 18° and 34° and with five different cover materials. afte...

Background: Identification of the dominant lactic acid bacteria involved in the production of traditional cheese in Semnan could be the initiative to protect national genetic resources and produce industrial cheese with desirable texture and organoleptic characteristics similar to traditional cheeses. The present study aimed to determine the biochemical, physiological, and phenotypic properties...

Traditional haymaking has created exceptionally high levels of plant species diversity in semi-natural grasslands of the Carpathian Mountains (Romania), the maintenance of which is jeopardized by recent abandonment and subsequent vegetation succession. We tested the hypothesis that the different life history strategies of dominant grasses cause different patterns of diversity loss after abandon...

Ann. Entomol. Soc. Am. 81(6): 899-912 (1988) ABSTRACT Insect populations infesting a small bulk of corn stored in southeastern Georgia were followed for 8 yr by monthly sampling beginning 8 mo after the corn was placed in storage. The species composition of the insect community changed as the corn deteriorated. Nine species became dominant at some stage of succession. Sitotroga cerealella (Oliv...

Abstract Hermit crabs community in the intertidal zones of Larak Island were investigated through a seasonal sampling at five stations using random quadrate sampling method. Overall, seven species were identified and Clibanarius signatus was the dominant species, which showed high dominance over other species. Using Bray-Curtis cluster analysis for comparing seasonal abundance showed that exce...

the morphological diversity of arbuscular mycorrhizal fungi (amf) at the anguran zn and pb mining region (zanjan province, iran) were studied along a transect from the mine to 4500 m away. within each plot, a composite sample of root and rhizospheric soil from a dominant indigenous plant was collected. the soil samples were analyzed for their physico-chemical characteristics. spores were extrac...

to evaluate the effect of crop rotation on spatial dynamic of fumaria vaillantti and polygonum aviculare a study was conducted at the three farms with different rotation in the astan ghods razavi filed that located at 10 kilometers southeast of mashhad, iran. the rotations were alfalfa- fallow- wheat, canola- fallow- wheat, and wheat- fallow- wheat. at the crosses of 7×7 m quadrangular grids ne...
