Diversity and distribution of echinoderms in the South Eastern Arabian Sea shelf under the influence of seasonal hypoxia
(Elsevier, 2018)The South Eastern Arabian Sea (SEAS) margin represents a tropical eastern boundary upwelling system, which is subjected to intense seasonal hypoxia in the continental shelf, and impingement of oxygen minimum zone (OMZ) ... -
Diversity and distribution of phytoplankton at Verem(Mandovi estuary) Goa
(Goa: Goa University, 2015)To understand diversity, distribution and the effect of environmental factors on phytoplankton, samples were collected fortnightly at Verem station in the Mandovi estuary during monsoon and non-monsoon period from June ... -
Diversity and extracellular enzyme activities of heterotrophic bacteria from sediments of the Central Indian Ocean Basin
(2019)Sedimentary bacteria play a role in polymetallic nodule formation and growth. There are, however, limited reports on bacterial diversity in nodule-rich areas of the Central Indian Ocean Basin (CIOB). In this study, bacterial ... -
Diversity and Functional Patterns of Benthic Amphipods in the Coralline Intertidal Zones of a Marine National Park, India
(Frontiers, 2020)Coralline intertidal habitats of marine protected areas (MPAs) are important model systems to investigate species diversity and ecological functioning of benthic communities. Spatial variability of amphipod species composition ... -
Diversity and impacts of macroalgae and cyanobacteria on multi-stressed coral reefs in the Gulf of Mannar Marine Biosphere Reserve
(Elsevier, 2023)In India, intertidal seaweed resources are widely investigated and utilized for various applications, whereas reef-associated seaweed resources and their impacts on corals are lesser known. Thus, the present study investigated ... -
Diversity and Quantitative Detection of Clade I Type nosZ Denitrifiers in the Arabian Sea Oxygen Minimum Zone
(Japanese Society of Microbial Ecology; Japanese Society of Soil Microbiology; Taiwan Society of Microbial Ecology; Japanese Society of Plant Microbe Interactions; Japanese Society for Extremophiles, 2023)A significant amount of nitrous oxide (N 2 O) is effluxed into the atmosphere as a result of marine denitrification in the Arabian Sea (AS) oxygen minimum zone (OMZ).An assessment of temporal variations in the diversity ... -
Diversity and seasonal distribution of ammonia-oxidizing archaea in the water column of a tropical estuary along the southeast Arabian Sea
(Springer Netherlands, 2018)Diversity and distribution pattern of ammonia-oxidizing archaea (AOA) were studied across a salinity gradient in the water column of Cochin Estuary (CE), a tropical monsoonal estuary along the southeast Arabian Sea. The ... -
Diversity in transcripts and translational pattern of stress proteins in marine extremophiles
(Springer, 2011)Extremophiles occur in a diverse range of habitats, from the frigid waters of Antarctic to the superheated plumes of hydrothermal vents. Their in-depth study could provide important insights into the biochemical, ecological ... -
Diversity of bacteria and fungi associated with tarballs: Recent developments and future prospects
(Elsevier, 2017)Tarballs are formed by weathering of crude oil in marine environment. They are transported from open ocean to the shores by sea currents and waves. Tarball pollution is a major concern to global marine ecosystem. Microbes ... -
Diversity of Bacterial Community in the Oxygen Minimum Zones of Arabian Sea and Bay of Bengal as Deduced by Illumina Sequencing
(2020)The Indian Ocean harbors oxygen minimum zones (OMZs) in the Arabian Sea and Bay of Bengal, with dissolved oxygen < 20 M, located at the mid-depths of the water column. Till date, high-throughput sequence-data on depth-wise ... -
Diversity of culturable nitrate-reducing bacteria from the Arabian Sea oxygen minimum zone
(Elsevier, 2018)The subsurface waters of the northern Arabian Sea display a pronounced oxygen minimum layer associated with high nitrite maxima which provide an ideal niche for organisms that can respire nitrate. Culture-based studies ... -
Diversity of culturable Sulphur-oxidising bacteria in the oxygen minimum zones of the northern Indian Ocean
(Elsevier B.V., 2020)Oxygen minimum zones (OMZs) are unique, widely spread and well-studied features of the global ocean, varying in seasonality and intensity. The Northern Indian Ocean contains OMZs in the Arabian Sea (AS-OMZ) and the Bay of ... -
Diversity of nitrite reductase genes (nirS) in the denitrifying water column of the coastal Arabian Sea
(Inter-Research, 2004)Denitrification often occurs in the water column, underlying zones of intense productivity and decomposition in upwelling regions. In the denitrifying zone off the southwest coast of India, high concentrations of nitrite ... -
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 ... -
Diversity of thraustochytrid protists isolated from brown alga, Sargassum cinereum using 18S rDNA sequencing and their morphological response to heavy metals
(Marine Biological Association of the United Kingdom, 2015)Thraustochytrids, the exclusively marine organisms of kingdom Stramenopila and a source of essential fatty acids in the marine milieu, possess an osmoheterotrophic mode of nutrition and are therefore affected by type and ... -
Diversity pattern of marine culturable heterotrophic bacteria in a region with coexisting upwelling and mud banks in the southeastern Arabian Sea
(Springer, 2022)Mud banks and upwelling are two important oceanographic features occurring along the southwest coast of India during the southwest monsoon period. The study region, Alappuzha lying on the southwest coast of India, is unique ... -
