Denitrification activity in mangrove sediments varies with associated vegetation
(Elsevier, 2016)
To test the hypothesis that mangrove vegetation associated sediment characteristics could influence an ecologically important function such as denitrification, a study was carried out at the Divar mangrove ecosystem in ...
Phosphate solubilizing bacteria: Comparison between coastal and deep sea sediments
(Centre for Ocean and Environmental Studies, New Delhi, 2012)
Phosphate solubilizing bacteria (PSB) play a key role in the phosphate cycle by enzymaticaly hydrolyzing a wide variety of organic phosphorus compounds and solubilizing various major insoluble forms of bound phosphorus. ...
Effects of composition of labile organic matter on biogenic production of methane in the coastal sediments of the Arabian Sea
(Springer, 2011)
Coastal regions are potential zones for production of methane which could be governed by ecological/environmental differences or even sediment properties of a niche. In order to test the hypothesis that methanogenesis in ...
An appraisal of biological responses and network of environmental interactions in non-mining and mining impacted coastal waters
(Springer, 2015)
The coastal waters of Goa and Ratnagiri lying on the West coast of India are influenced by terrestrial influx. However, Goa is influenced anthropogenically by iron-ore mining, while Ratnagiri is influenced by deposition ...
Denitrification activity is closely linked to the total ambient Fe concentration in mangrove sediments of Goa, India
(Elsevier, 2013)
Denitrification activity is closely linked to the total ambient Fe concentration in mangrove sediments of Goa, India Denitrification activity (DNT) and associated environmental parameters were examined in two mangrove ...
Predominance of anaerobic bacterial community over aerobic community contribute to intensify ‘oxygen minimum zone’ in the eastern Arabian Sea
(Elsevier, 2011)
The presence of a delicately poised mid-depth oxygen minimum zone (OMZ) makes the Arabian Sea a unique and important ecosystem. So far, various aspects responsible for its formation have been studied. However, the contributions ...
Mathematical modeling of the evolution of a simple biological system
(India Environment Portal, Centre for Science and Environment, 2013)
As a part of teaching of physics it is common to record data on evolution of a physical system and then construct a mathematical model of the system. For example, movement of a simple pendulum can be recorded, and then a ...
Grazing of particle-associated bacteria - An elimination of the non-viable fraction
(Elsevier, 2017)
Quantification of bacteria being grazed by microzooplankton is gaining importance since they serve as energy subsidies for higher trophic levels which consequently influence fish production. Hence, grazing pressure on ...
Spatio-temporal variations in sulfur-oxidizing and sulfate-reducing bacterial activities during upwelling, off south-west coast of India
(2019)
The Arabian Sea, off SW India, is becoming more anoxic in recent years. Poor ventilation
affects microbial degradation of organic matter in oxygen minimum zone (≤2.85 ml l -1 O 2 , ≤0.02µM
NO 2 ) and anoxic marine zone ...
Marine organisms and their adaption - Adaptions solve the challenges of existence in the sea.
(Centre for Environmental Studies, 2009)
Marine organisms exist in an ever-changing environment. The physical environment within the ocean varies with the availability of light, oxygen, food resources, pressure and temperature. This variation in the physical ...
