Emergent and floating macrophytes in relation to some  physicochemical parameters were assessed in Waya pond, Bauchi. Water and macrophytes were sampled monthly between October 2019 to March 2020. Ten physicochemical parameters were measured and twelve macrophytes species recorded. The diversity index was 1.38, evenness (0.55) and abundance were 12 species. The site was polluted as all the values of dissolved oxygen (DO) were ˂ 5 mg/L, nitrogen ˃ 18 mg/L and pH ˂ 7 except for December.  Pearson’s correlation coefficient revealed that DO correlated with Total Dissolved Solids (TDS) (r = 0.936, p˂0.01), Phosphate (r = 0.927, p˂0.01) and Nitrate (r = -0.953, p˂0.01). TDS correlated with Phosphate (r = 0.969, p˂0.01) and Nitrate (r = - 0.938, p˂0.01). The significant correlation between physicochemical parameters and macrophytes were: Nymphaea nouchali with DO (r = - 0.849, p˂0.05), TS (r = 0.88, p˂0.05). Panicum repens was negatively correlated with TDS, DO, TS, Phosphate but not Nitrates. Eichhornia crassipes, Nymphaea micrantha and Nymphaea lotus at p˂0.05 were negatively associated with TDS, DO, and Phosphate but positively with Nitrate. Nuphar lutea, Nelumbo nucifera and Echinochloa colona related positively with Turbidity. Nuphar lutea positively related with Nitrate but negative with DO, and TS. Typha latifolia with TS (r = - 0.871, p˂0.05). Potamogeton natans with phosphate (r = 0.927, p˂0.01). The state of water pollution in the study-area corresponded with low diversity, evenness and abundance of species. This puts biodiversity and sustainability at risk.

Raw Wastewater

In Ethiopia, most of the coffee processing plants are generating large amounts of wastewater with high pollutant concentrations and discharge directly into the water bodies untreated or partially treated. The main objective of this study was to assess the effects of coffee wastewater discharged to river water quality using physicochemical parameters and macro-invertebrate indices. This study was conducted from November to the end of December 2019. Ten wastewater and river water samples were taken from coffee the processing plant and river. The macro-invertebrate samples were collected by kick sampling technique using a standard hand net. Shannon and Simpson diversity indices were examined at 3 sampling stations. The Pielou evenness index was also determined. It was found that except for TDS all the parameters of the raw wastewater and river water did not comply with the international discharge limit. The mean concentration of Faro coffee processing plant wastewater were BOD5 (2409.6 ± 173.1 mg/L), COD (4302 ± 437 mg/L), TSS (2824.6 ± 428.4 mg/L), TDS (3226 ± 623.6 mg/L), and TS (4183.3 ± 432.9 mg/L). Whereas from Bokaso coffee processing plant were BOD5 (3770 ± 604.4 mg/L), COD (4082.6 ± 921.9 mg/L), TSS (2766 ± 501.7 mg/L), TDS (3017 ± 747.6 mg/L), and TS (3874 ± 471.1 mg/L). A total of 392 macroinvertebrates belonging to 24 families and 7 orders were collected. The benthos assemblage communities in this river were 40, 56, and 296 at downstream 1, downstream 2, and upstream respectively. The value of the Simpson diversity index varies from 0.4 to 0.75. In the same manner, the value of the Shannon diversity index also varied from 0.5 to 1.36. Most of the physicochemical parameters of the raw wastewater were beyond the national and international discharge limits. The quality of Orsha river water downstream was more adversely affected compared to upstream.

In this study, 50 Vibrio cholerae O1 serotype Inaba isolates were collected during several cholera outbreaks throughout Iran during the summer of 2005. The results of antibiotic susceptibility testing showed that 86, 84, 84 and 82 % of the isolates were resistant to streptomycin, chloramphenicol, co-trimoxazole and tetracycline, respectively. The strains were genotyped using randomly amplified polymorphic DNA (RAPD), PFGE and ribotyping techniques. PCR showed that 100, 98 and 98 % carried the ctx, zot and ace genes, respectively. Biochemical fingerprinting of the isolates using the PhenePlate (PhP) system showed a low diversity index level (0.755), suggesting that the strains were highly homogeneous. Among the strains, 100 and 96 % showed an identical ribotype and PFGE patterns, respectively. The two isolates showing different PFGE patterns also exhibited discrete PhP types. RAPD was able to discriminate the isolates into six distinct groups, suggesting some genetic dissimilarity was present among the strains. These ribotyping, PFGE and PhP techniques revealed the clonal dissemination of a single V. cholerae strain throughout Iran in 2005.

Abstract Salvinia herzogii, Pistia stratiotes and Eichhornia crassipes (floating species) were the dominant macrophytes in a constructed wetland (CW) over the first years of operation. Later, the emergent Typha domingensis displaced the floating species, becoming dominant. The industrial effluent treated at this CW showed high pH and salinity. The aim of this work was to study the tolerance of floating species and T. domingensis exposed to different pH and salinity treatments. Treatments at pH 8, 9, 10 and 11 and salinities of 2,000; 3,000; 4,000; 6,000; and 8,000 mg L−1 were performed. Floating macrophytes were unable to tolerate the studied pH and salinity ranges, while T. domingensis tolerated higher pH and salinity values. Many industrial effluents commonly show high pH and salinity. T. domingensis demonstrated to be a suitable macrophyte to treat this type of effluents.

Bosten Lake was the largest inland freshwater lake in China. It is facing with a series of ecological problems nowadays. The phytoplankton and water samples of seventeen sampling sites in Bosten Lake were collected in September 2012. Results show that sixty-four species (genera) of phytoplankton, which belong to six phyla, are identified. The community structure of phytoplankton is dominated by Chlorophyta. The mean cell density of phytoplankton in whole lake is 8179.01×104cells·L-1 and Cyanophyta accounts for 94.71%. The dominant species are Chroococcus sp. and Synedra acus. In terms of Shannon-Wiener diversity index, Margalef richness index, Pielou evenness index and total nitrogen content, it is ascertained that trophic state of water body in Estuary and Pumping Station is between mesotrophication and eutrophication. While in the other districts, the water body is eutrophic. In addition, the eutrophic degree of water body in District IV is higher.

<p><em>The purpose of this study was to determine the diversity of soil insect orders in the reclamation area of former limestone quarries in the top soil type, spoil and reject product used in the media for land reclamation processes. This research sampling technique uses a pitfall trap tool. This study used descriptive quantitative data analysis using the Shannon-Wiener diversity index, Simpson dominance index, Pielou species evenness index, and index of Morisista-Horn habitat similarity. Based on the research that has been done it can be concluded that the reclamation land in 2010 with the dominant type of dust has a low diversity category and a high dominance category with the discovery of 4 orders. The reclaimed land in 2014 with the dominant clay type soil has a moderate diversity category and a low dominance category with 7 orders found. Whereas the reclamation land in 2016 with the dominant type of sand has a low diversity category and a high dominance category with the discovery of 8 orders. The spread of species in all three locations was categorized evenly and between locations did not have the same community. </em></p>
