Comparative in vitro study on free radical scavenging potential of selected bivalve species
(Matttioli 1885, Italy, 2012)Bivalves such as, Crassostrea spp., Meretrix casta, Placuna placenta and Polymesoda erosa are largely consumed as edible seafood. It forms natural source of nutrition in coastal and worldwide population. Free radical ... -
Ecological observations and GC-MS analysis of methanolic extract of Sacoglossan Elysia bangtawaensis (Swennen)
(National Environmentalists Association, 2012)Elysia bangtawaensis Swennen (sacoglossan) was reported from intertidal mangrove habitat from the polyhaline zone of Mandovi estuary, Goa. The detailed ecological survey of the mangrove region of Goa revealed that the ... -
Absolute calibration of SARAL/AltiKa in Kavaratti during its initial calibration-validation phase
(Taylor and Francis, 2015)The Kavaratti calibration-validation site in India at Lakshadweep Sea has been improved to carry out absolute calibration of SARAL/AltiKa altimeter. This site is augmented with a down-looking radar gauge and a permanent ... -
Relationship between the lability of sediment-bound Cd and its bioaccumulation in edible oyster
(Elsevier, 2015)A linkage between Cd speciation in sediments and its bioaccumulation in edible oyster (Crassostrea sp.) from a tropical estuarine system was established. Bioaccumulation of Cd in edible oyster increased with the increasing ... -
Southwest monsoon influences the water quality and waste assimilative capacity in the Mandovi estuary (Goa state, India)
(Taylor and Francis, 2015)The monsoon-dominated Mandovi estuary is located in Goa state – a global tourist destination along the centralwest coast of India. In addition to factor analyses of water quality data, the water quality index (WQI), trophic ... -
Is climate change triggering coral bleaching in tropical reef?
(Current Science Association, 2015)Analysis of SST data of this region, derived from the Giovanni on-line data system , developed and maintained by NASA GESDISC, revealed 1.02°C and 1.61°C rise in temperature above normal during 2014, in summer and winter ... -
Picophytoplankton as tracers of environmental forcing in a tropical monsoonal Bay
(Springer, 2015)In order to better understand the picophytoplankton (PP) dynamics in tropical monsoon influenced coastal regions, samples were collected daily (June–September 2008: monsoon, December 2008: post-monsoon and April 2009: ... -
