Article Abstract

One of the main challenges in phytoplankton ecology is to understand their variability at different spatiotemporal scales. We investigated the interannual and cyclone-derived variability in phytoplankton communities of Chilika, the largest tropical coastal lagoon in Asia and the underlying mechanisms in relation to environmental forcing. Between July 2012 and June 2013, Cyanophyta were most prolific in freshwater northern region of the lagoon. A category-5 very severe cyclonic storm (VSCS) Phailin struck the lagoon on 12th October 2013 and introduced additional variability into the hydrology and phytoplankton communities. Freshwater Cyanophyta further expanded their territory and occupied the northern as well as central region of the lagoon. Satellite remote sensing imagery revealed that the phytoplankton biomass did not change much due to high turbidity prevailing in the lagoon after Phailin. Modeling analysis of species-salinity relationship identified specific responses of phytoplankton taxa to the different salinity regime of lagoon.

Sri Lanka is uniquely situated at the junction of the Bay of Bengal (BOB) and the Arabian Sea (AS), where phytoplankton community may be strongly influenced by ocean dynamical processes, particularly mesoscale eddies and the East Indian Coastal Current (EICC). Here, to explore these regulatory mechanisms, phytoplankton and physicochemical parameters were collected from the top 200 m water column in the eastern and southern seas of Sri Lanka during the winter monsoon. Results showed higher concentrations of nutrients and phytoplankton abundance within the regions affected by EICC and cyclonic eddy (CE) compared to anticyclonic eddy (ACE).

Climate change and anthropogenic pressures alter phytoplankton phenology, distribution, and bloom frequency. Healthy phytoplankton communities are crucial for biogeochemical processes, blue carbon sequestration, and climate change mitigation. By employing high-throughput 18S V4 rRNA metabarcoding, we addressed the need for profiling phytoplankton community and response mechanisms in urbanized coastal ecosystems.

The emergence of new types of pollutants and the increase of anthropogenic load on the environment provoked an increased interest of researchers to study the toxic effects of pollutants on living organisms. This study is devoted to investigate the physiological response of the Black Sea phytoplankton community to the effects of ZnO, CuO and TiO nanoparticles (NPs) of different concentrations by creating in vitro model microcosms. Trends of changes in the ratio between phytoplankton groups (cyanobacteria-picoeukaryotic algae-nano-microphytoplankton), species composition, growth rates and functional state of cells under the influence of the studied nanoparticles were revealed.

Marine heatwaves (MHWs) are increasing in frequency and intensity worldwide, significantly impacting marine ecosystems. However, studies on phytoplankton community changes in coastal waters under such conditions remain. In the summer of 2024, an extreme high-temperature event (>28 °C) occurred in the southern coastal waters of Korea, providing an opportunity to investigate phytoplankton community dynamics under thermal stress.

Phytoplankton, as primary producers, play a key role in aquatic ecosystems. Their community turnover is shaped by morphological traits that enable adaptation to diverse abiotic and biotic factors. Yet, the temporal scale of these dynamics remains poorly understood due to limited high-frequency sampling studies.
