The Diversity and Abundance of Littoral Dinophyta and Dinocyst in Chicoco-Mud along the Lower Reaches of the New - Calabar River, Niger-Delta, Nigeria
Journal Title: International Journal of Environment, Ecology, Family and Urban Studies (IJEEFUS) - Year 2019, Vol 9, Issue 2
Abstract
A total of 15 Chicoco-mud samples were randomly sampled at extreme low neap or spring tides from five Stations located within three communities in Asari-Toru Local Government Area of Rivers State for dinophyta and dinocyst studies, covering wet and dry seasons. The planktological taxonomic system was adopted. Seasonal variations were minimal with low diversity and abundance values, nevertheless, in the wet season, average Margalef’s Species Richness Index (d) varied from 0.271 – 0.511, Shannon-Weiner Diversity Index (H) varied from 0.244 – 0.461 bits/Individual (bits/Ind.) and Equitability (E) from 0.193 – 0.988 while in dry season ‘d’ varied from 0.271 – 0.542, ‘H’ from 0.092 – 0.471 bits/Ind. and ‘E’ from 0.193 – 0.988, however, Hutcheson t -test for ‘H’ between Stations indicated ‘significant’ and ‘not-significant’ differences at P < 0.05 level. The most abundant species amongst the dinophyta were the ‘resting cyst’ producing species of Polykrikos schwartzii Bütschli (Gymnodiniales) and Preperidinium meunieri (Pavillard) Elbrächter (Peridiniales) while for the dinocyst it was Protoperidinium spp. (Peridiniales). Chicoco-mud ‘stations’ and ‘monthly’ physicochemical data indicated that Sand, Silt, Clay, Fiber, Wet conductivity, TOC, pH, Avail. P., and NO-3 – N were significantly different and affected the diversity and abundance of littoral dinophyta and dinocyst.
