Multiple ash layers in late Quaternary sediments from the Central Indian Basin
(Elsevier, 2016)
We have investigated three sediment cores collected from water depths > 5000 m along the transect 76°30`E in close proximity to a fracture zone in the Central Indian Basin (CIB). The cores yielded five volcanic horizons ...
Distribution, provenance and early diagenesis of major and trace metals in sediment cores from the Mandovi estuary, western India
(Elsevier, 2016)
Major elements and trace metals were analyzed in four sediment cores recovered along a transect in the Mandovi estuary for their distribution, provenance and early diagenesis. The sediments were clayey silts in cores from ...
Carbon dioxide emissions from the tropical Dowleiswaram Reservoir on the Godavari River, Southeast of India
(Scientific Research Publishing, 2013)
Time-series observations were conducted in the Dowleiswaram dam reservoir that was constructed on the largest monsoonal river in India to understand the source of inorganic carbon, and fluxes to the atmosphere. The reservoir ...
Simple electric powered plankton wheel for the production of aggregates in seawater on-board ship
(NISCAIR, CSIR, 2011)
A new handy plankton wheel was devised for use on-board a ship. Its efficacy to generate aggregates was tested on land using coastal waters. The device successfully generated aggregates of sizes varying up to 11.3 mm sup(2) ...
Dimensional Relationships in Crassostrea madrasensis (Preston) and C. gryphoides (Schlotheim) in Mangrove Ecosystem
(NISCAIR (CSIR), 2011)
Mangrove influenced estuarine habitats in the tropics favor the settlement of oysters and their larval stages, which protect them from strong waves and speedy currents. Shell structure in Bivalves form an important protective ...
Effect of eyestalk extirpation on haemolymph ionic concentration of Metapenaeus monoceros
(Horizon Publisher, 2013)
Metapenaeus monoceros in the size range 65-70mm was subjected to the evaluation of sodium(Na<sup>+</sup>),, potassium (K<sup>+</sup>) and calcium (Ca<sup>2+</sup>) ionic concentration in the haemolymph after unilateral ...
Bacillus mangrovi sp. nov., isolated from a sediment sample from a mangrove forest
(Microbiology Society, 2017)
A facultatively anaerobic, endospore forming, alkali-tolerant, Gram-stain-positive, motile, rod-shaped bacterium, designated strain AK61T, was isolated from a sediment sample collected from Coringa mangrove forest, India. ...
Seasonal variations in abundance, biomass and grazing rates of microzooplankton in a tropical monsoonal estuary
(Springer, 2015)
Seasonal abundance, composition and grazing rates of microzooplankton (20–200 µm) in the Zuari estuary were investigated to evaluate their importance in food web dynamics of a tropical monsoonal estuary. Average abundances ...
Effect of pea crab Pinnotheres vicajii (Chhapgar, 1957) on immunocompetence of bivalve Paphia malabarica (Chemnitz, 1782)
(Elsevier, 2017)
The endosymbiont-host relationship between a pea crab and its bivalve host has been studied previously using bivalve�s multi-physiological parameters. The present study is first of its kind that uses hemocyte�s immune ...
Exposure of Eichhornia crassipes (Mart.) Solms to salt water and its implications
(Current Science Association, IAS, 2017)
In this article, we discuss the effect of salinity on the viability and decomposition of Eichhornia crassipes plant under normal photoperiod, dark condition and physiological response. Highest concentration of total organic ...
