Seasonal variation in bacterial community composition and Seasonal variation in bacterial community composition and β-glucosidase expression in a tropical monsoon-influenced estuary
(Inter Research, 2017)Tidal estuaries receive carbohydrate-rich organic matter from various sources, which are mainly broken down by enzymatic processes. ?-glucosidase (?-Glu) is one of the ectoenzymes produced by heterotrophic bacteria. An ... -
Robustness of observation-based decadal sea level variability in the Indo-Pacific Ocean
(Wiley, 2017)We examine the consistency of Indo-Pacific decadal sea level variability in 10 gridded, observation-based sea level products for the 1960-2010 period. Decadal sea level variations are robust in the Pacific, with more than ... -
Defaunation of meiofauna in Mumbai bay (India) - A severely polluted area
(Elsevier, 2017)Meiofauna plays an important role in the benthic food web of shallow water ecosystems. In the present study, the status of meiofauna was addressed in the intertidal and subtidal environment of Mumbai bay (West coast of ... -
Diversity of sediment-associated Planctomycetes in the Arabian Sea oxygen minimum zone
(Wiley, 2017)We examined the diversity of Planctomycetes in the sediment sample collected from an oxygen minimum zone (OMZ) in the southeast Arabian Sea. A 16SrRNA gene library was constructed using the forward primer specific for ... -
Intense reducing conditions during the last deglaciation and Heinrich events (H1, H2, H3) in sediments from the oxygen minimum zone off Goa, eastern Arabian Sea
(Elsevier, 2017)Two sediment cores, ABP-32/GC-01R and ABP-32/GC-03 were collected at a water depth of 642 m and 1086 m off Goa from the present day Oxygen Minimum Zone (OMZ) of eastern Arabian Sea (EAS) cover time span of last 18 ka and ... -
Increased CO 2 availability promotes growth of a tropical coastal diatom assemblage (Goa coast, Arabian Sea, India)
(Taylor & Francis, 2017)Responses of tropical coastal phytoplankton assemblages to increasing CO2 levels are poorly known. The Arabian Sea (AS), the western part of the north Indian Ocean, is an upwelling-induced, highly productive region, but ... -
Cluster analysis of benthic foraminiferal morpho-groups from the western margin of India reflects its depth preference
(Elsevier, 2017)Q-mode and R-mode cluster analyses have been carried out on the census counts data of 68 genera and one �other genera� of benthic foraminifera from 32 stations off Mangalore-Cochin sector, west coast of India, to study the ... -
Marine paleoclimatic proxies: A shift from qualitative to quantitative estimation of seawater parameters
(Elsevier, 2017)Understanding past climate during contrasting boundary conditions can help in assessing imminent climate changes. Marine sediments offer a vast archive of past climate. Various indirect methods called proxies are used to ... -
Impact of seasonal changes in nutrient loading on distribution and activity of nitrifiers in a tropical estuary
(Elsevier, 2018)Estuaries are ecologically important environments, which function as the reception point of nitrogenous inputs of terrestrial and anthropogenic origin. In the present study, we discuss the influence of nutrient characteristics ... -
Seasonality in autotrophic mesoplankton in a coastal upwelling-mud bank environment along the southwest coast of India and its ecological implications
(Elsevier, 2017)Mesoplankton refers to both autotrophic and heterotrophic�plankton�with a body size between 200 � 20,000��m. Here, we applied a FlowCAM to identify the�autotrophs�present in the mesoplankton size class in a�coastal ... -
Differential environmental responses of tropical phytoplankton community in the southwest coast of India
(Elsevier, 2017)Phytoplankton characteristics (biomass, primary productivity, species composition and community structure) were studied in a tropical estuary (Cochin estuary) and adjacent coastal marine region for understanding the factors ... -
Feeding preference and daily ration of 12 dominant copepods on mono and mixed diets of phytoplankton, rotifers, and detritus in a tropical coastal water
(Springer, 2017)Results of the experimental studies on the feeding habit and daily ration (DR) of 12 dominant copepods from a tropical coastal water (off Kochi, Southwest coast of India) on different food items (phytoplankton, rotifers, ... -
Long-term preservation of Tetraselmis indica (Chlorodendrophyceae, Chlorophyta) for flow cytometric analysis: Influence of fixative and storage temperature
(Elsevier, 2017)Immediate enumeration of phytoplankton is seldom possible. Therefore, fixation and subsequent storage are required for delayed analysis. This study investigated the influence of glutaraldehyde (GA) concentrations (0.25%, ... -
Taxonomy and distribution of benthic foraminifera in an intertidal zone of the Yellow Sea, PR China: Correlations with sediment temperature and salinity
(Elsevier, 2017)Seasonal variations in foraminiferal populations from the intertidal environment of the Yellow Sea are not well known. This results in restricted understanding of environmental implications of foraminifera and their ... -
Marine macroalgal nursery: A model for sustainable production of seedlings for large scale farming
(Elsevier, 2018)Innovative technologies in seaweed aquaculture are the need of the hour for sustaining the emerging global market demands. The supply of seedlings for year-round sea farming has remained as a major challenge for large-scale ... -
Interannual variability of zonal currents in the equatorial Indian Ocean: respective control of IOD and ENSO
(Springer, 2017)The observational record is too short to confidently differentiate the relative contributions of Indian Ocean Dipole (IOD) and El Ni�o-Southern Oscillation (ENSO) on the interannual variability of the equatorial current ... -
A simple method to forecast the frequency of depressions and cyclones over Bay of Bengal during summer monsoon season
(Springer, 2018)In this study, an attempt has been made to develop a simple multiple regression model to forecast the total number of depressions and cyclones (TNDC) over Bay of Bengal during summer monsoon (June-September) season using ... -
Microbial dynamics in a tropical monsoon influenced estuary: Elucidation through field observations and microcosm experiments on biofilms
(Elsevier, 2017)The changes that occur in biofilms reflect the influence of the environment. In a case study, the biofilms developed along a salinity gradient from marine to freshwater in a tropical monsoon influenced estuary (Zuari, west ... -
40Ar/39Ar dating of the Mumbai tholeiites and Panvel flexure: intense 62.5 Ma onshore-offshore Deccan magmatism during India-Laxmi Ridge-Seychelles breakup
(Oxford University Press, 2017)Mumbai, located on the western Indian continental margin, exposes Danian-age Deccan magmatic units of diverse compositions, dipping seaward due to the Panvel flexure. The Ghatkopar-Powai tholeiitic sequence contains ... -
Metabolic regulatory oscillations in intertidal green seaweed Ulva lactuca against tidal cycles
(Nature Publishing Group, 2017)The survival of wetland plant species largely relies on physiological adaptations essential for submergence and desiccation. Intertidal seaweeds, unlike terrestrial plants, have unique adaptations to submergence and can ...
