Kerala is a state on the southwest corner of the Indian peninsula gifted with 44 rivers. Dams have been built across all the major river systems of Kerala in the southern parts of the Western Ghats, creating around 53 reservoirs (Harikumar & Rajendran, 2007). Despite this fact, algal studies are few in the dams of Kerala. In a phycological perspective, only Idukki reservoir (Sebastian & Thomas, 2016), Kanhirapuzha dam (Palaniswamy et al., 2019) and algae from 12 reservoirs of Kerala (Ray et al., 2021) were studied.At all Indian level, many dams studied for algae.

“…Species identification was made using a Zeiss NR183268 series microscope and by referring to the descriptions, drawings, dimensions and photographs in available dichotomous keys [43][44][45][46], Update name of species and their natural environment were obtained by referring to catalogs and websites available online [11,[47][48][49][50][51][52]. In each assemblage the weighed mean sensitivity (WWS) of the diatom community was determined and the trophic diatom index (TDI) was calculated.…”

A survey was undertaken from March to June 2014 on the biodiversity and the community structure of Chromista Cavalier-Smith, 1981 in Nyong and Kienke River mouths (South-Cameroon). In each river, raw waters were collected from upstream to downstream at four sites. Cells were counted using the Malassez cells procedure and species were identified. A total of 10427.1x105 cells corresponded to three phyla, eight classes, 23 orders, 32 genera and 40 species (24 freshwater species (60.0% of total species richness and total collection respectively), three marine species (7.5% and 2.4% of the total species richness; and total collection respectively), and one brackish water specialist in Kienke (2.5% and 5.1%), 13 tolerant species (32.5% and 32.6%)). The trophic diatom index revealed undisturbed conditions with no or little alteration of human origin and a low organic pollution (oligotrophic or mesotrophic state) (Nyong: TDI=52.7; Kienke: TDI=69.7; pooled assemblage: TDI=65.0). A low species richness was detected (richness ratio in Nyong: d=0.008; Kienke: d=0.003; pooled rivers: d=0.004), a high species diversity (Shannon index close to maximum) (Nyong: H’=2.742 and H’max=2.996; Kienke: H’=2.685 and H’max=2.996; pooled rivers: H’=3.245 and H’max=3.689), a very low dominance by a few species (Berger-Parker index close to 0) (Nyong: IBP=0.156; Kienke: IBP=0.175; pooled rivers: IBP=0.134), and Hill’s ratio were close to 1 (Nyong: Hill=0.819; Kienke: Hill=0.803; pooled rivers: Hill=0.722). The community was highly even with a high value of the Pielou’s evenness close to 1 (Nyong: J=0.915; Kienke: J=0.896; pooled rivers: J=0.880). Two useful species and one harmful species to fish were rare in Kienke. Species exhibited in Kienke and pooled data in rainy season, a positive global net association while it was negative in Nyong. Assemblage fitted Preston’s model in Nyong with a high environmental constant in the dry season (m’=1.469), low constant in the rainy season (m’=0.947) and the pooled seasons (m’=0.853). In Kienke constants were low (dry season: m’=0.574; rainy season: m’=0.566; pooled seasons: m’=0.581) suggesting a evolved community in less disturbed environments where the majority of species showed moderate abundances. In the dry season, the pooled assemblage functionned on the basis of maintaining a complex information network (close to ecological balance) developed at spatio-temporal scales (ZM model) and it presented a low force of regeneration (fractal dimension of the distribution of individuals among species (1/γ)=0.925<1). The evolved oligotrophic state (close to natural balance) of the chromists’ community should be preserved and protected and the studied rivers classified as reference.
