Environmental-driven dynamics of phytoplankton assemblages in the Bay of Bengal, Southeast coast of India
A study conducted from January to December 2018 examined seasonal variations in horizontal phytoplankton communities. A total of 93 species were identified, including 63 Coscinodiscophyceae, 4 Fragilariophyceae, 7 Bacillariophyceae, 15 Dinophyceae, and 4 Cyanophyceae. The highest species diversity and abundance occurred during the postmonsoon and premonsoon periods. Environmental parameters (viz., temperature, salinity, dissolved oxygen, pH, ammonia, nitrite, silicate, total suspended solids) were all statistically significant except for nitrite (p > .05). Multivariate statistical analyses (PCA and CCA) revealed that in the postmonsoon period, silicate and nitrate were responsible for the proliferation of phytoplankton abundance, species composition and density, while in the premonsoon period, temperature, salinity, and pH significantly influenced and favored specific phytoplankton groups (such as Chaetocerotaceae) in terms of species composition and abundance.
期刊介绍：
Marine Ecology publishes original contributions on the structure and dynamics of marine benthic and pelagic ecosystems, communities and populations, and on the critical links between ecology and the evolution of marine organisms.
The journal prioritizes contributions elucidating fundamental aspects of species interaction and adaptation to the environment through integration of information from various organizational levels (molecules to ecosystems) and different disciplines (molecular biology, genetics, biochemistry, physiology, marine biology, natural history, geography, oceanography, palaeontology and modelling) as viewed from an ecological perspective. The journal also focuses on population genetic processes, evolution of life histories, morphological traits and behaviour, historical ecology and biogeography, macro-ecology and seascape ecology, palaeo-ecological reconstruction, and ecological changes due to introduction of new biota, human pressure or environmental change.
Most applied marine science, including fisheries biology, aquaculture, natural-products chemistry, toxicology, and local pollution studies lie outside the scope of the journal. Papers should address ecological questions that would be of interest to a worldwide readership of ecologists; papers of mostly local interest, including descriptions of flora and fauna, taxonomic descriptions, and range extensions will not be considered.
