Phytoplankton chlorophyll-breakdown pathway: Implication in ecosystem assessment
(2020)
The chlorophyll-breakdown to pheophorbide is determined by biotic factors such as grazing (via chlorophyllide) or senescence (via pheophytin). So far, much of the information on chlorophyll-breakdown is available from ...
Changes in the ballast water tank bacterial community during a trans-sea voyage: Elucidation through next generation DNA sequencing
(Academic Press, 2020)
Ballast water (BW) mediated bioinvasion is one of the greatest threats to the health of aquatic ecosystems. Bacteria, unlike higher organisms, are transferred in large numbers through BW. Owing to their abundance and ...
Macrobenthic diversity and community structure at Cochin Port, an estuarine habitat along the southwest coast of India
(2020)
Estuarine habitats are highly dynamic owing to tidal and seasonal changes in physical and chemical properties, which, in turn, have a profound influence on the diversity and community structure of its living components. ...
Short term response of plankton community to nutrient enrichment in central eastern Arabian Sea: Elucidation through mesocosm experiments
(Elsevier, 2021)
Oligotrophic waters (OW), generally favour longer food chain facilitated by the microbial loop. In such ecosystems, physical mixing (e.g. upwelling, and winter convection) inject nutrients and propagules from subsurface ...
Fatty acids as indicators of sediment organic matter dynamics in a monsoon-influenced tropical estuary
(Elsevier, 2021)
Sedimentary organic matter (OM) composition serves as a biomarker and helps in hindcast analysis of the events in the habitat. The present study was carried out on a monthly basis to evaluate the contribution of different ...
Environmental influence on the picophytoplankton community structure in the central and northern Bay of Bengal
(Elsevier, 2020)
The Bay of Bengal (BoB) is a low productive, oligotrophic ecosystem. The picophytoplankton (Pico; < 3mu m) play a significant role in the biogeochemistry of such ecosystems. The information on the Pico is exiguous from ...
Picophytoplankton community dynamics in a tropical river estuary and adjacent semi-enclosed water body
(Springer, 2021)
The dynamics of picophytoplankton, a vital component of the aquatic microbial food web, are least explored in the river-dominated estuaries, especially those subjected to human modifications that can alter the hydrodynamics ...
Dinoflagellates cyst assemblage concerning trophic index for eutrophication from major ports along the west coast of India
(Elsevier, 2022)
An overview of dinoflagellates cysts assemblage is presented as a trophic index for three monsoon-influenced estuarine and marine ports along the Indian coast. The cyst distribution (including harmful species) showed a ...
Benthic-pelagic coupling assessed using phytoplankton marker pigments: a case study from the Paradip port, East Coast of India
(Springer, 2022)
This study addresses the seasonal distribution of phytoplankton marker pigments (PMP) and the ratios (indicating freshness and fate) from water and surface sediments from the coastal port ecosystem (Paradip port, Odisha, ...
How does frontal age influence physiological status of bacteria: a case study from the Northeastern Arabian Sea
(Springer, 2021)
Sea surface temperature fronts in the Northeastern Arabian Sea (NEAS) facilitate nutrient enhancement in the surface layers, resulting in high primary production. Such high production areas contribute to the accumulation ...
