Abstract. This research was investigated the seasonal changes in phytoplankton, bacterioplankton and autotrophic picoplankton as well environmental parameters photic layer of Lake Baikal. Using microscopy methods, 43 species belonging to Bacillariophyta, Dinophyta, Chlorophyta, Chrysophyta, Cryptophyta, Haptophyta, Charophyta Cyanoprokaryota have been identified. Bacillariophyta Chlorophyta wer...

Algae were diagnosed in three stations at seasons for 2018-2019 the Tigris River. It was with 158 species five main divisions (Chlorophyta, Bacillariophyta, Cyanophyta, Pyrrhophyta and Euglenophyta). Chlorophyta division represented 14 genera 33 a percent of 20.88%, Bacillariophyta 22 genus 84 53.16%, Cyanophyta was14 41 25.94%, pyrrhophyta four 2.53%, Euglenophyta one 0.63%. The study also sho...

The updated version of PLMItRNA reports information and multialignments on 609 genes and 34 tRNA molecules active in the mitochondria of Viridiplantae (27 Embryophyta and 10 Chlorophyta), and photosynthetic algae (one Cryptophyta, four Rhodophyta and two Stramenopiles). Colour-code based tables reporting the different genetic origin of identified genes allow hyper-textual link to single entries...

The composition and abundance of phytoplankton in the waters are strongly influenced by supply phosphorus light intensity, so observations were made to obtain optimum concentration with a certain level which caused high Lake Cikaret. A 2 x factorial design was used see effect three levels (0.03 mg/L, 0.09 0.15 mg/L) (30%, 70% 100% luminance). on phytoplankton. parameters observed phytoplankton,...

Abstract Milkfish is a brackish-water cultured fish that widely cultivated in traditional ponds because the business capital relatively small and feed provided only from natural food form of plankton. This study aims to determine type plankton stomach frequency feeding occurence milkfish order preferred by milkfish. used survey method. The composition found consists 8 divisions, namely Bacillar...

Taxonomic, nomenclatural and distributional changes since the publication of 2011 edition (reprinted 2021) The Freshwater Algal Flora British Isles (“Flora”) are reviewed together with some overlooked earlier. Many more recent a result studies combining an analysis morphological DNA sequence data. Of 473 reported most concern Chlorophyta (131) Charophyta (156) followed by Cyanobacteria (101), a...

Simple Sequence Repeats (SSRs) or microsatellites constitute a significant portion of genomes however; their significance in organellar genomes has not been completely understood. The availability of organelle genome sequences allows us to understand the organization of SSRs in their genic and intergenic regions. In the present work, SSRs were identified and categorized in 14 mitochondrial and ...

Recently, prophylactic use of antibiotics in livestock have been banned by European Community with the consequence of a growing research towards new, safe and natural ingredients, like plant extract, that would have antimicrobial properties [1]. In this context, seaweed extracts have assumed great importance in animal nutritionfor the high content in bioactive molecules [2]. Seaweed or marine m...
