Along the Indian coast, oysters were identified and studied since the beginning of the 20th century. One of the first records on the taxonomy of Indian oysters is by Hornell (1910) [2]. Since then a series of reports on the taxonomy of Indian oyster were made[1,3,4-9]. Originally the Indian oysters were referred to under the genus Ostrea but was later included under the genus Crassostrea. Anoth...

Development of oil and natural gas deposits off Sakhalin's northern coast on the Sea of Okhotsk are currently under way. Should an accident involving a spill of crude oil or other effluents occur during the development of the oil and natural gas deposits that is currently under way off the eastern coast of northern Sakhalin, it can be expected to have an impact on the environment and economy of...

Marine records from the northern Gulf of Mexico indicate that significant multidecadaland century-scale variability was common during the Holocene. Mean annual sea-surface temperature (SST) during the last 1,400 years may have varied by 3C, and excursions to cold SST coincide with reductions in solar output. Broad trends in Holocene terrestrial climate and environmental change along the eastern...

Floods have repeatedly battered the South Indian state, Kerala, as a result of unprecedented heavy rainfall during Boreal Summers, in recent years. The state witnessed large departures from normal 2018 and 2019. Previous studies seldom adopted systematic approach to understand phenomenon responsible for recurrent extreme events. Hence, this study, based on spectral methods, identifies character...

BACKGROUND Dengue is a global human public health threat, causing severe morbidity and mortality. The occurrence of sequential infection by more than one serotype of dengue virus (DENV) is a major contributing factor for the induction of Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS), two major medical conditions caused by DENV infection. However, there is no specific drug or va...

The traditional architecture of Kerala, a state in India lying along its southwest coast, is known for its use of natural and passive methods for a comfortable indoor environment. Although there have been attempts to analyze the traditional architecture of Kerala, they were focused only on qualitative approach. An investigation was thus initiated by the authors to understand the passive environ...

A total of 173 actinomycetes colonies were isolated from near shore marine environment and mangrove ecosystem at 8 different locations of Kerala, West Coast of India. Among them, 64 isolates were morphologically distinct on the basis of spore mass colour, reverse side colour, aerial and substrate mycelia formation and production of diffusible pigment. The majority (47%; n=30) of these isolates ...

Ctenophores are poorly known in the tropical eastern Pacific, including the southern coast of Mexico. Previous records of ctenophores along the Pacific coast have been provided mainly from northern waters. For the coast of Oaxaca state, their occurrence has only been mentioned before at phylum level. In this paper, we provide the first three records of ctenophores for the Oaxacan coast, which r...
