<abstract xmlns="http://www.w3.org/1999/xhtml">58 species and infraspecies of Chlorophyta and Charophyta algae were observed in 60 samples collected in September 2017 from the Shah Alam River, Pakistan. The algal species richness and environmental variables increased down the river, except for pH. Bioindication revealed low saline, low alkaline, middle streaming, and middle oxygenated water with low to middle organic pollution with Index saprobity S 1.48-1.73, Class 2-3 of Water Quality. The trophic state was eutrophic and meso-eutrophic with increasing eutrophication down the river. River Pollution Indices RPI demonstrated increasing of pollution in the Shah Alam River in comparison with the parallel part of the Kabul River.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">Many species of phaeophyta are found at Dwarka and at the Bet-Shankhodhar coast, Gujarat, India. For the study of <italic>Iyengaria stellata</italic>, the shore platform and reef flat were divided into three sections: Dwarka in i) North, ii) Centre and iii) South sections and Bet-Shankhodhar in i) West, ii) Centre and iii) East sections. <italic>I. stellata</italic> was monitored based on systematic random sampling for two years (April, 2013 to February, 2015). In the months of December and February, <italic>I. stellata</italic> was recorded with high frequencies of reef, flat zones and shore platforms. When compared to shore platform, the frequency of <italic>I. stallata</italic> was highest in coral reef and flat zones. This study supports that reef flat is very suitable for growth of <italic>I. stellata</italic>. <italic>I. stellata</italic>’s growth cycle corresponds with local winter season.</abstract>

Habitat Preference of Phaeophyceae Species: <italic>Iyengaria stellata</italic> (Børgesen) Børgesen (1939) in Gujarat Coast (India)

<abstract xmlns="http://www.w3.org/1999/xhtml">This article reveals factors that need to be considered by facilitating institutions and organisations prior to adoption of scientific indicators in community-based monitoring of mangrove ecosystems; as a necessary route towards achieving effective participation and meaningful experiential learning processes. It employs an Experiential Learning Intervention Workshop (ELIW) as a key methodological tool and a useful space for analysing conditions that are necessary for adoption of scientific frameworks in the Tanzanian coastal area. ELIW also offers an opportunity for local people to share knowledge and decide the kind of input required for monitoring mangroves and fisheries.</abstract>

Factors that Determine the Adoption of Scientific Indicators in Community-Based Monitoring of Mangrove Ecosystems in Tanzania

<abstract xmlns="http://www.w3.org/1999/xhtml">Stream dwelling invertebrate populations are facing an ample array of stressors including the habitat imbalance caused by important floods. In this research we used a novel way to estimate the impact of floods upon the substrate, by utilising a remote variable named “flash-flood potential” (FFP), which accounts for the site slope and the average slope of the upstream catchment. The results showed that certain groups are sensitive to the influence of the FFP whereas other are not. We propose this remote variable as a surrogate for assessing stress imposed by floods and sediment scouring for lotic macroinvertebrates.</abstract>

Flash-Floods Influence Macroinvertebrate Communities Distribution in Lotic Ecosystems

<abstract xmlns="http://www.w3.org/1999/xhtml">It was suggested that the darkness environment would influence the fishes’ morphology, not only the barbells, snout, but also the male secondary sexual features. This paper reported that the three typical cave dwelling fish species of <italic>Triplophysa</italic> did not show these sexual morphological traits, such as <italic>Triplophysa lewangensis, Triplophysa nasobartula</italic> and <italic>Triplophysa zhenfengensis</italic> collected in Guizhou Province, meanwhile, there were not the description on the traits about the 11 typical cave dwelling species of this genus in Guangxi Province.</abstract>

The Disappearance of Male Secondary Sexual Characteristics in the Typical Cave Species in <italic>Triplophysa</italic>

<abstract xmlns="http://www.w3.org/1999/xhtml">This research was undertaken to find out the levels of five heavy metals (Cu, Fe, Mn, Pb, and Zn) in the muscles of eight fish species from Epe Lagoon. The levels of heavy metals were determined by atomic absorption spectrophotometry after digestion of the samples using Kjldahl heating digester. The heavy metal concentrations among the fish species were statistically dissimilar (P &lt; 0.5). The heavy metals of Pb, Fe, and Mn were above the FAO/WHO agreeable limits for human consumption.</abstract>

Heavy Metal Concentration in Eight Fish Species from Epe Lagoon (Nigeria)

<abstract xmlns="http://www.w3.org/1999/xhtml">The lotic habitats quality indicative congeners species <italic>Gobio gobio, Gobio kessleri</italic> and <italic>Gobio albipinnatus</italic> populations’ dynamic in time (2004-2019) and space revealed a decreasing trend in these rivers ecological status. The ADONIS:CE tool has been used to build a backing management system model, based on these indicative fish species habitat needs, indicators for favourable conservation status, pressures and threats. This management system implementation in the field will favour the amelioration of lotic habitats and the ecological status recovering of two of the local fish species of conservative interest (<italic>G. kessleri</italic> and <italic>G. albipinnatus</italic>).</abstract>
