Abstract
Water Chemistry, Microscopy and Algal Pigment Concentration Analyses of Phytoplankton in the Western and Eastern Parts of The Lagos Lagoon.
Highlights
Phytoplankton contributes at least twenty-five percent of the world’s vegetation and constitutes the base of the food web in aquatic ecosystems (Jeffrey and Vesk, 1997)
The salinity values ranged between 0.08 and 17.32 0/0, with the highest value recorded in March in the with the highest concentration recorded in March (Western) axis and the lowest value was recorded in November and in the Eastern side
The highest was recorded in March (Western) while the lowest was recorded in November (Eastern), with a mean value of 5.98 mg/L, 5.93 mg/L for the Western and Eastern axis respectively
Summary
Phytoplankton contributes at least twenty-five percent of the world’s vegetation and constitutes the base of the food web in aquatic ecosystems (Jeffrey and Vesk, 1997). The phytoplankton constitutes plant drifters of the aquatic environment, which are usually microscopic. They form the first step in the aquatic food chain with the zooplankton forming the second step (Onyema and Okedoyin, 2017). Dinoflagellates, blue-green algae, chlorophytes and so on are some important groups of phytoplankton in brackish and marine ecosystems. Spatiotemporal or seasonal variations and regimes of these environmental factors are crucial in the levels and estimates of phytoplankton diversity, abundance or density of individuals as well as estimated levels of algal pigments recorded per time (Onyema et al, 2017). Algal pigment concentrations are currently applied to quantify and qualify phytoplankton communities (Wu et al, 2014)
