Nitrogen fixation and carbon uptake in a tropical estuarine system of Goa, western India
Ahmed, A.; Naik, H.; Adel, S.S.; Bardhan, P.; Gauns, M.; Naik, B.; Naqvi, S.W.A. (Elsevier, 2019)Biological production in aquatic systems is often nitrogen limited. Nitrogen (N2) fixation is an important contributor to nitrogen requirement of phytoplankton not only in oligotrophic but also in nutrient-replete waters. ... -
Nitrogen fixation rates in the eastern Arabian Sea
Ahmed, A.; Gauns, M.; Kurian, S.; Bardhan, P.; Pratihary, A.K.; Naik, H.; Shenoy, D.M.; Naqvi, S.W.A. (Elsevier, 2017)The Arabian Sea experiences bloom of the diazotroph Trichodesmium during certain times of the year when optimal sea surface temperature and oligotrophic condition favour their growth. We measured nitrogen fixation rates ... -
Phytoplankton dynamics in a seasonal stratified reservoir (Tillari), Western India
Ahmed, A.; Gauns, M.; Shenoy, D.M.; Kurian, S.; Naik, H.; Naqvi, S.W.A. (EDP Sciences, 2021)Phytoplankton are the primary producers in all the aquatic ecosystems and play an important role in key biogeochemical processes that are linked to the higher trophic levels and climate variability. The present study deals ... -
Phytoplankton succession in a tropical freshwater lake, Bhoj Wetland (Bhopal, India): spatial and temporal perspective
Ahmed, A.; Wangane, A. (Springer, 2015)Bhoj Wetland is tropical freshwater system in central India "Bhopal" serving the citizens as one of the major source of water since its inception Understanding the process of phytoplankton variation can be particularly ... -
Spatial variability in phytoplankton community structure along the eastern Arabian Sea during the onset of south-west monsoon
Ahmed, A.; Kurian, S.; Gauns, M.; ChndrasekharaRao, A.V.; Mulla, A.; Naik, B.; Naik, H.; Naqvi, S.W.A. (Elsevier, 2016)The Arabian Sea experiences moderate to weak upwelling along the south-west coast of India, which subsequently propagates towards the north. This causes variation in plankton community composition, which is addressed in ... -
Spatial variability of microzooplankton in the central Arabian Sea during spring intermonsoon
Elangovan, S.S.; Gauns, M.; Mulla, A.; Ahmed, A. (John Wiley & Sons, 2018)Spatial variability of microzooplankton (MZP; organisms in size 20-200 -m) along with total heterotrophic bacteria (THB) and picophytoplankton in the upper 120-m water column of the central Arabian Sea (AS) was studied ...
