the plankton and semi-plankton samples examined from mizoram state of northeast india (nei) revealed speciose and diverse rotifera assemblage including a total richness (s) of 162 species belonging to 19 families and 35 genera. the reports of six species new to india, four species new to nei and 76 new records to mizoram merit biodiversity interest. the occurrence of one australasian, one orien...
Annexed to this report are selected and revised working papers presented to the meeting. The working paper from ICLARM is included under the' authorship of Pauly and Smith. Tropical Waters, Report of the ACMRR Working Party on the management of living resources in near-shore tropical waters. The research process and communication of results: lessons learned from a multidisciplinary analysis of ...
This study shows a range extension for the Australian blacktip shark Carcharhinus tilstoni, which was believed to be restricted to Australia's tropical waters, of >1000 km into temperate waters, revealing its vulnerability to a wider commercial fishery.
Bird flocks associated with dolphins in the eastern tropical Pacific are described from observations obtained during eight cruises that took place from January to March of 1976, 1977, 1979, and 1980. In the northern tropical waters between latitudes 5”N and 30”N, 43% to 53% of bird flocks co-occurred with dolphins. In equatorial and southern subtropical waters between latitudes 5”N to 12”s and ...
Community composition of Bacteria in the surface and deep water layers were examined at three oceanic sites in the Pacific Ocean separated by great distance, i.e., the South China Sea (SCS) in the western tropical Pacific, the Costa Rica Dome (CRD) in the eastern tropical Pacific and the western subarctic North Pacific (SNP), using high throughput DNA pyrosequencing of the 16S rRNA gene. Bioinf...
Much is known about deep ocean ambient noise, rather less about the more highly structured and variable noise in temperate coastal waters, and rather little about the tropical shallow waters that include coral reefs and the biological diversity these ecosystems support. Interest in shallow water acoustics has been growing over the last decade, and more recently specific interest has bloomed in ...
Biogeochemical processes are driven jointly by mass flux and metabolism, but biogeochemical contrasts across latitude are more strongly related to metabolism than to mass flux. Metabolism can be expressed in terms of metabolic potential, which is regulated by temperature, irradiance, and chemical feedstocks (nutrients, electron acceptors, organic matter). Metabolic potential of autotrophs in tr...
The Lusitania Province has been considered a transition zone between the Atlantic northern cold waters and Tropical warm waters. Tropical species have expanded their ranges during warm periods and either retreated during cold periods or survived in local refuges. Successive waves of dispersion into this Province could have favored diversification through geographic isolation. Taxa that remained...
A bimonthly coral-based record of the postbomb radiocarbon content of Solomon Sea surface waters is interpreted to reflect mixing of subtropical surface water and that advected in from the east by the equatorial branch of the South Equatorial Current (SEC). Annual mean D14C has a dynamic range of nearly 175‰, with a total range of nearly 200‰. Prebomb values average 256‰ and the annual mean pos...
