Temperature- and size-associated differences in the skeletal structures and osculum cross-sectional area influence the pumping rate of contractile sponge Cinachyrella cf. cavernosa
(2019)Sponges alter the proportion of structural and morphological components such as spicule skeleton and number of oscula in response to environment, development and growth. Such mechanisms indicate morphological and physiological ... -
Temporal and ephemeral variations in copepod community in the estuaries of Mandovi and Zuari - west coast of India
(Cambridge Univ. Press, UK, 2001)In the tidal-dominated coastal plain estuaries, the magnitude of temporal and ephemeral variations in the abundance of the calonoid copepod community was evaluated over two annual cycles by two-way ANOVA. The species by ... -
Temporal and spatial variability of trace metals in suspended matter of the Mandovi estuary, central west coast of India
(Springer, 2012)Studies on the suspended particulate matter (SPM) in the Mandovi estuary, western India indicate that during the monsoon and pre-monsoon, the SPM increases, and the major and trace metals decrease from stations in the ... -
Temporal and spatial variations in hydrographic conditions of Mandovi estuary
(CSIR-NISCAIR, 1975)Nine stations over a stretch of 21 km of Periyar river estuary were sampled during January to December 1981. Particulate matter varied from 3-253 mg.1 super(1) at the surface and 24.8-257mg.1 super(1) at the bottom. ... -
Temporal and spatial variations in particulate matter, particulate organic carbon and attenuation coefficient in Cochin Backwaters
(CSIR-NISCAIR, 1989)Nine stations over a stretch of 21 km of Periyar river estuary were sampled during January to December 1981. Particulate matter varied from 3-253 mg.1 super(1) at the surface and 24.8-257mg.1 super(1) at the bottom. ... -
Temporal derivative of Total Solar Irradiance and anomalous Indian summer monsoon: An empirical evidence for a Sun–climate connection
(Elsevier, 2011)Identifying the pattern of natural climate variability is of immense importance to delineate the effects of anthropogenic climate changes. Global and regional climates are suspected to vary, in unison or with delays, with ... -
Temporal effect on the abundance and diversity of intertidal rocky shore macroalgae
(Current Science Association, IAS, 2017)A study of the temporal effect on the abundance and diversity of intertidal rocky shore macroalgae re-vealed that there are ~70 species in the intertidal rocky shore of Anjuna (60 species) and Vagator (52 species) in Goa, ... -
Temporal variability in copepod gut pigments over the central western continental shelf of India
(Cambridge University Press, 2018)The Indian Western continental shelf (IWCS) is amongst the most productive regions of the world, being noteworthy for upwelling (south-west monsoon) and downwelling (north-east monsoon) that tunes the water biogeochemistry. ... -
Temporal variability of atmospheric particulate-bound polycyclic aromatic hydrocarbons (PAHs) over central east India: sources and carcinogenic risk assessment
(Springer, 2022)Atmospheric polycyclic aromatic hydrocarbons (PAHs) are of significant interest owing to their high potential health effects, including mutagenicity and carcinogenicity. We report 16 PAHs measured in ambient PM2.5 from ... -
Temporal variability of macrofauna from a disturbed habitat in Zuari estuary, west coast of India
(Springer, 2011)Natural disturbances along with human interference make the tropical estuaries amongst the most disturbed areas globally. In spite of this, information on the seasonal variability of macrofauna from tropical estuaries is ... -
Temporal variation in macroinvertebrates associated with intertidal sponge Ircinia fusca (Carter 1880) from Ratnagiri, West coast, India.
(CSIR-NISCAIR, 2014)Temporal variation of macrofauna associated with a marine sponge, Ircinia fusca was studied from a tropical rocky shore along the West coast of India. Triplicate sponge samples (~100 g) were collected from January to ... -
Temporal variation of diatom benthic propagules in a monsoon-influenced tropical estuary
(Elsevier, 2008)Temporal variations in the diatom benthic propagule (DBP) community and their role in the phytoplankton community in a monsoon-affected tropical estuary, Zuari estuary, Goa (India) are presented. The DBP from the sediments ... -
Temporal variations in dimethylsulphoniopropionate and dimethyl sulphide in the Zuari estuary, Goa (India)
(Elsevier, 2003)Despite tropical estuarine systems representing important sites for active biogeochemical processes, studies on dimethyl sulphide (DMS) in these systems are sparse. Here we report on DMS and dimethylsulphoniopropionate ... -
Temporal variations in the chemical composition of aerosols over the coastal Bay of Bengal
(Elsevier, 2022)Variations in source, ionic composition and carbonaceous components of aerosols are expected in the atmosphere due to reversing the direction of winds from winter to summer over the coastal Bay of Bengal (BoB). To examine ... -
Temporal variations in the wind and wave climate at a location in the eastern Arabian Sea based on ERA-Interim reanalysis data.
(European Geosciences Union, 2014)Temporal variations in wind speed and significant wave height (SWH) at a location in the eastern Arabian Sea are studied using ERA-Interim reanalysis data from 1979 to 2012. A shallow water location is selected for the ... -
Temporally invariable bacterial community structure in the Arabian Sea oxygen minimum zone.
(Inter-Research, 2014)The Northeastern Arabian Sea (NEAS) is a recognized region of intense denitrification, with a 200 to 1200 m anoxic water column. We studied the abundance of bacteria, viral particles and the bacterial community (BC), in ... -
Terrestrial and marine bioluminescent organisms from the Indian subcontinent: a review
(Springer Science and Business Media Deutschland GmbH, 2020)The inception of bioluminescence by Harvey (1952) has led to a Nobel Prize to Osamu Shimomura (Chemistry, 2008) in biological research. Consequently, in recent years, bioluminescence-based assays to monitor toxic pollutants ... -
