Coral reefs of India, their conservation and management
Coral reefs are natural gift to mankind, and are built in thousands
of years by millions of tiny coral polyps. Reefs give food for mankind,
material for scientific research, ample opportunities for recreation
and past time. We need the reef, reefs need our attention; certainly
we should keep them for future generation
Coral reef ecosystems
Coral reefs constitute the most dominant marine
benthic ecosystem of tropical seas. The complexity of.
the biotic and abiotic interactions, coupled with rich
biodiversity of reef dwelling and reef building fauna
and flora are comparable to those prevailing in tropical
rain forests. Several important problems related
to coral reefs all over the world, such as, biodiversity,
biogeochemical cycles, nutrient flux, environmental
degradation and ecological collapse, exploitation of
reef resources- their conservation and
management, have been addresse
An assessment of the effects of environment and human interference on the coral reefs of Palk Bay and Gulf of Mannar along the Indian Coast
The environmental and man-made changes that affects the coral growth and associated
animals and fishery in Palk Bay and Gulf of Mannar along the Indian coast are discussed.
Quarrying of corals for industrial use has turned out to be a serious threat to the
reefs. Removal of corals in several places has caused settlement of sand and growth
of sea-grass and algae at former sites of well developed reefs
Corals
Corals art objects of beauty and utility. They are found only in the sea, mainly
in tropical and subtropics1 regions. Only very few, other than students of biology know
that they are sedentary animals possessing a hard internal or external skeleton. They have
attracted the attention of the biologists only recently and several problems related to them
are still not explained to our fullest satisfaction. Earlier naturalists regarded them as marine
plants, probably due to their sedentary habit and plant-like growth form, It was only in
the latter half of the cigbteenth century Peyssonnel proved the animal nature of corals,
But even middle nineteenth century students of natural history assigned them a place only
between animals and plants and wore accordingly called 'zoophytes'
A review of the status of corals and coral reefs of India
Precise estimation of the biodiversity of corals from any area is subject to variation due to uncertainty of synonymy.
Corals exhibit very high intraspecific skeletal variation depending on the physiographic and hydrographic condition.
The present paper describes overview of coral resources in Indian seas, their biology and taxonomy, anthropogenic
stress on coral reefs, conservation and research efforts being put by various organisation
Marine Biodiversity: Conservation and management-Introduction
There has been a realisation in the latter part of twentieth century
on the imperative need to protect and conserve the habitats and their
resources. In the Biodiversity convention at the UN Conference on
Environment and Development (UNCED) the term biodiversity is
defined as "the variability among living organisms from all sources
including inter alia, terrestial, marine and other ecosystems and the
ecological complexes of which they are part, this includes diversity
within species, between species and of ecosystems.
Report on the Stony Corals from the Maldive Archipelago
The Maldive Archipelago, situated at the southwest of India, consists of 22 atolls, extending over a length of nearly 470km in a north-south direction. The northern limit is Ihavandiffulu Atoll (7"'05'N, 72' 55'E), while Addu, one of the scientifically well known atolls, is located at the southern tip (0' 40'5, 73'1 O'E). The largest among the Maldivian atolls is located in the northern half of the chain and is known by twO names, a nonhern smaller part called Tiladummati, and the southern part Miladummadulu. At the middle pan of the Archipelago the atolls are arranged in two almost parallel rows, incorporating a great number of Faros with their small lagoon-like water bodies, termed Velu. The type locality of Atolls and Faros are the Maldives, the names originating from the Maldivian language. Nearly 2000 small islands enter into the geography of the Maldives, of which circa 200 are inhabited with a population of nearly 120000
Report on the Stony Corals from the Red Sea
The first to mention corals of the Red Sea was Thomas SHAW, who travelled through Tunisis , Algeria, Egypt, Syria and the Sinai Peninsula, and who in his "Travels or observations re lati ng to several parts of Barbary and the Levant" described 24 corals of Et Tur (1738, German edition 1765). From these one can recognize P1atygyra, Favia, Goniastrea, Acropora, Stylophora and Tubipora, but his Latin descriptions
are not sufficient for an identification at a species level
Scleractinian corals from the Gulf of Kutch
The Scleratinian corals of the Gulf of Kutch from the north-west coast of India is taxonomically
analysed. The coral fauna include 37 species among 24 genera. Out of these, 20 genera with 33
species are hermatypec and the rest 4 genera and 4 species is ahermatypes. Early mention in literature
on the occurrence of genera such as Pavona, Podabacia, Leptoria and Lobophyllia from the Gulf of
Kutcb is not taken into account, since these records are based on unconfirmed determinations. All
genera and species considered are widespread in the Indo-Pacific coral provinces and no new species
is described herein
Environmental deterioration in Lakshadweep and need for conservation of living resources
The Lakshadweep Archipelago is located on the Laccadive - Chagos ridge, believed to be the submarine extension of the Aravalli mountains. The various atolls rise from a depth ranging from 1500 to 4000 m. The Lakshadweep Archipelago consists of 12 atolls, 3 reefs and 5 submerged banks, all of coral formations. The total land area is about 32 sq km. The height of islands vary from 1 to 1.4 m from MSL
