The regression of similarity against distance unites several ecological phenomena, and thus provides a highly useful approach for illustrating the spatial turnover across sites. Our aim was to test whether rates decay in community differ between diatom growth forms suggested show different dispersal ability. We hypothesized that group with lower ability (i.e. periphyton) would higher than plankton).Periphyton phytoplankton samples were gathered at sites distributed over an area approximately...
SUMMARY 1. During the spring of 1992, fifty‐two quantitative diatom samples were collected from twenty‐eight rivers located in Tokyo Metropolitan area, Japan, to study response assemblages water pollution (assessed using physical and chemical data determined monthly April 1987 March 1992). 2. Species composition was analysed by means biotic indices (Pantle Buck's saprobic index) multivariate analyses [two‐way indicator species analysis (TWINSPAN) for classification canonical correspondence...
Response of epilithic diatom communities to environmental gradients in subtropical temperate Brazilian riversThis work aims analyse the response southern rivers contribute development a widely applicable methodology for water-quality monitoring.Samples physical, chemical and biological determination were collected monthly, from December 2001 November 2002 March 2003 February 2004, at 9 stations along Pardo Pardinho hydrographical basin Rio Pardo, State Grande do Sul (RS), Brazil.Physical...
The microalgae Desmodesmus subspicatus (Chlorophyta) was cultivated in a tubular photobioreactor using effluent from the wastewater treatment plant of University Santa Cruz do Sul, Brazil to demonstrate reactor's operation. algae's ability remove nutrients and oleaginous potential biomass were also evaluated. Total phosphorus ammonia nitrogen measured. consisted system three acrylic tubes, reservoir, connections CO2 supply. gas supply semicontinuous with added cylinder. culture's growth...
Abstract Population growth and increasing production demands threaten the highly diverse Andean freshwater ecosystems. Biological indicators constitute a valuable tool for evaluating ecological quality of ecosystems under different pressures. Diatom macroinvertebrate assemblages are most used bioindicators to assess water pollution, whereby these biotic groups occupy first second trophic levels respond habitat pollution. Several studies have explored response communities pollution in other...
This research evaluated the effectiveness of implementation water resource preservation areas in Hydrographical Basin Andreas Stream, county Vera Cruz, RS, Brazil, established through Payment for Environmental Services (PES), using an environmental monitoring program to assess physical, chemical and microbiological variables. The PES is linked "Water Guardian" project, which aims ensure resources by paying farmers providing services protect springs riparian that lie within their properties....
AIM: The main objective was to evaluate the efficiency of sewage treatment plant (STP) UNISC, through ecotoxicological characterization and analyses physical, chemical microbiological variables from raw treated effluent. METHODS: Samples were collected during 2008 2009 for performing acute toxicity (Daphnia magna), chronic (Ceriodaphnia dubia), as well determination environmental variables. RESULTS: results indicated with an EC(I)50 48 hours average 64.1 ± 9.9%, characterized moderately...
Abstract This research aimed to study the composition of epilithic diatom flora found in samples collected Cali River hydrographical basin, Colombia. Quarterly excursions (March, June, September and December 2012 March 2013) were performed six sampling sites collect for identification organisms (Class Bacillariophyceae). The results indicated occurrence 82 taxa distributed 26 families 38 genera. 32 these are new occurrences most representative Gomphonemataceae, Naviculaceae Bacillariaceae....
