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. ...
Spatio-temporal Variations in Bacterial Abundance with an Emphasis on Fecal Indicator Bacteria and Vibrio spp. in and around Visakhapatnam Port, East Coast of India
(UGM Press, 2020)
The ecological health of port environments, which are dynamic and hotspots of anthropogenic activities, can be analyzed using specific pathogenic bacteria as they provide definite evidence and source of pollution. The ...
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 ...
Phytoplankton communities in marine intertidal rock-pools: Effect of location, geometric shapes and allelopathy
(Springer, 2021)
Biologically rich rock-pools (RPs) are prominent component of rocky intertidal habitat and this study elucidates the factors aAecting the phytoplankton distribution from high-tide (HT), mid-tide (MT) and low-tide (LT) RPs ...
Response of the bacterial metagenome in port environments to changing environmental conditions
(Elsevier, 2021)
Port environments are highly dynamic and hotspots for marine bioinvasion. This study investigated the bacterial diversity at two geographically distant ports (Mangalore-marine port; and Haldia-riverine port) using ...
Seasonal cycle of zooplankton standing stock inferred from ADCP backscatter measurements in the eastern Arabian Sea
(Elsevier, 2022)
We use ADCP (acoustic Doppler current profiler) backscatter, measured during October 2012 to December 2020 at three locations on the continental slope in the eastern Arabian Sea (EAS), to study the seasonal variation in ...
