Occurrence of cyanobacteria - diatom symbiosis in the Bay of Bengal: Implications in biogeochemistry
(Current Science Association, 2010)
Diazotrophs (N sub(2) fixing organisms), mainly belonging to cyanobacteria, form a major group of phytoplankton in nutrient poor oligotrophic oceans. These organisms support non-diazotrophic phytoplankton community and ...
Effect of monsoonal perturbations on the occurrence of phytoplankton blooms in a tropical bay
(Inter-Research, 2015)
In this study, the influence of intraseasonal variations in rainfall and the resultant freshwater flux (monsoon perturbations) on phytoplankton bloom dynamics were evaluated by quantifying live phytoplankton at a fixed ...
Simulation experiments to elucidate variable fluorescence as a potential proxy for bulk microalgal viability from natural water, sediments and biofilms: Implication in ships ballast water management
(Elsevier, 2018)
The variable fluorescence fluorometry measuring microalgal biomass (initial fluorescence - F0, a chl-a proxy) and photosynthetic efficiency (Fv/Fm) has been suggested as a potential tool in ballast-water assessment. In ...
Benthic dinoflagellate blooms in tropical intertidal rock pools: Elucidation of photoprotection mechanisms
(Springer, 2017)
Intertidal rockpools (RPs), forming a ubiquitous component of rocky shores, are biologically rich ecosystems influenced by short-term (hours-days) and long-term (days-seasons) fluctuating environments. So far, studies on ...
Variations in phytoplankton community in a monsoon-influenced tropical estuary
(Springer, 2011)
In a monsoon-affected tropical estuary, oscillations in freshwater discharge during monsoon shifted the phytoplankton blooms from those adapted to low salinity to high salinity and vice versa. Salinity stratification during ...
A first look at the dinoflagellate cysts abundance in the Bay of Bengal: implications on Late Quaternary productivity and climate change
(Current Science Association, 2012)
Abundance and composition of dinoflagellate cysts in a sediment core (SK218/1) from the Bay of Bengal were examined for the last 23 kyr. Cyst abundance at this site varied from 20 to 153 cysts/g dry wt, which is far less ...
Dinoflagellate planktonic-motile-stage and benthic-cyst assemblages from a monsoon-influenced tropical harbour: Elucidating the role of environmental conditions
(2019)
Dinoflagellates are referred among potential bioinvaders and environmental proxies. Information from tropical regions on the coupling of cyst and motile stages of dinoflagellates characterized by high suspended-load, and ...
Efficiency of copper and cupronickel substratum to resist development of diatom biofilms
(Elsevier, 2015)
This study on the population dynamics of fouling diatoms from a biofouling rich monsoon influenced tropical bay revealed that irrespective of the season and exposure period, the highest diatom abundance and species were ...
Assessment of phytoplankton photo-physiological status from a tropical monsoonal estuary
(2019)
Assessment of phytoplankton physiological responses to abiotic changes provides valuable insights into the health of an ecosystem. The variable fluorescence (F v = F m -F 0 ), photosynthetic efficiency (F v /F m ), and ...
Dinoflagellate cyst distribution in recent sediments along the south-east coast of India
(Elsevier, 2013)
The spatial variation in the dinoflagellate cyst assemblage from the south-east coast of India is presented along with a comparison of the cyst abundance from other regions of the world Samples from 8 stations revealed the ...
