A new species of the genus Sagitta (Phylum Chaetognatha) from the Agatti lagoon (Laccadive Archipelago, Indian Ocean) with comments on endemism
(Council of Scientific and Industrial Research, New Delhi, 1999)A new chaetognath Sagitta madhupratapi from the Agatti atoll, Laccadive Archipelago is described. The species belongs to the "hispida" group. Though collections were made from other atolls the species was found restricted ... -
Studies on experimental culture of a marine ciliate Fabrea salina
(Oxford and IBH, Calcutta, 1999)Studies were conducted on the culture of a marine ciliate, Fabrea salina in the laboratory condition. Three types of inert feed; commercial yeast, fermented wheat bran and fermented rise bran were tested to study their ... -
Abundance, viability and culturability of Antarctic bacteria
(Department of Ocean Development, New Delhi, India, 1999)The viability of total number of bacteria decide the mineralisation rate in any ecosystem and ultimately the fertility of the region. This study aims at establishing the extent of viability in the standing stock of the ... -
Parthenogenetic reproduction of Diaphanosoma celebensis (Crustacea: Cladocera). Effect of algae and algal density on survival, growth, life span and neonate production
(Springer, 1999)The cladoceran Diaphanosoma celebensis Stingelin is reported on for the first time from Indian waters (Mandovi Estuary, Goa). Amictic females were maintained in the laboratory (temperature 24 plus or minus 1 degrees C and ... -
Observations on feeding behaviour and survival rates in the estuarine calanoid copepods Acartia spinicauda and Heliodiaptomus cinctus (Crustacea: Copepoda: Calanoida)
(Council of Scientific and Industrial Research, New Delhi, 1999)Experiments were conducted on the calanoid copepods, Acartia spinicauda (Acartiidae) and Heliodiaptomus cinctus (Diaptomidae) in order to determine food preference and survival rates respectively. Adults of A. spinicauda ... -
Volvatellin, caulerpenyne-related product fromt he sacoglossan Volvatella sp.
(American Chemical Society, 1999)Volvatellin (4) is a highly unstable terpene isolated from the extracts of the Indian opisthobranch mollusk Volvatella sp. The structure and the relative stereochemistry of 4 were determined by NMR methods. The paper also ... -
Status and strategies for marine biodiversity of Goa
(ICMAM-PD, Chennai (India), 1999)The status of marine biodiversity and factors responsible for the degradation and loss of marine biodiversity are discussed. Goa has abundant marine wealth. Phytoplankton, marine algae, manglicolous fungi, seagrasses, ... -
Asia Pacific Mangrove Information Network (APMIN): A conceptual model
(International Society for Mangrove Ecosystems, Okinawa, Japan, 1999)Asia Pacific Mangrove Information Network (APMIN), its structure and scope, is discussed in this paper. Establishment of National Mangrove Information Centers (NMIC) in 20 Asia-Pacific countries, would contribute towards ... -
New scalaranes from the nudibranch Glossodoris atromarginata and its sponge Prey
(American Chemical Society, 1999)Two new scalaranes (1 and 2) have been isolated from the dorid nudibranch Glossodoris atromarginata and its prey. The structures were determined by spectral techniques and confirmed by chemical methods. Compounds 1 and 3 ... -
Thraustochytrid fungoid protists in faecal pellets of the tunicate Pegea confoederata, their tolerance to deep-sea conditions and implication in degradation processes
(Inter-Research, 1999)During a swarm of the tunicate Pegea confoederata (salp) in the northern Arabian Sea, we examined their faecal pellets for thraustochytrid protists and bacteria to understand the role of the former in decomposition processes ... -
Immediate response of meio and macrobenthos to disturbance caused by a benthic disturber
(International Society of Offshore and Polar Engineers, Cupertino, CA (USA), 1999)The probable impact of nodule mining on benthic biota was studied by creating a benthic disturbance. During the predisturbance study in the Central Indian Basin, box core samples were analyzed for the distribution, composition ... -
Ecology of the wood-boring bivalve Martesia striata (Pholadidae) in Indian waters
(Academic Press, 1999)Martesia striata is one of the dominant wood-boring organisms found in Indian waters. Incidence of this organism in the Zuari estuary (Goa) was evaluated by exposing wooden panels (Mangifera indica) to the marine environment ... -
Free-living copepods of the Arabian Sea: Distributions and research perspectives
(Council of Scientific and Industrial Research, New Delhi, 1999)The subclass Copepoda consists of 10 orders and exhibit great diversity in morphology as well as the habitats they occupy. Within the orders themselves, there are sometimes overlaps-some are free living or could be parasitic. ... -
Antifungal activity of some marine organisms from India, against food spoilage Aspergillus strains
(Kluwer, 1999)Crude aqueous methanol extracts obtained from 31 species of various marine organisms (including floral and faunal), were screened for their antifungal activity against food poisoning strains of Aspergillus. Seventeen species ... -
