It extends from Kanyakumari in the south to Rameswaram in the north. The importance of the Gulf of Mannar lies in the fact that it has a chain of 21 islands along a stretch of 140 km in between Rameswaram and Tuticorin. Although, all the islands are small and uninhabited, they are surrounded by a rich diversity of corals and associated ornamental and food fishes. The Gulf of Mannar Biosphere Re- serve (GOMBR), because of its possession of a variety of resources including corals, seagrasses, seaweeds, pearl oysters, sacred chanks, turtles, crabs, lobsters, shrimps, fishes, seahorses and the endangered seacows is a rich bio-diversity area. Gulf of Mannar in recent years has been encountering a variety of threats, both natural and anthropogenic, which might tell upon the sustainability of the marine resources in the region. Although the creation of a Marine National Park and protection of the Gulf of Mannar as a Marine Biosphere Reserve are on the agenda of the managers, the threats posed by a variety of sources need to be addressed in order to take suitable measures so that the marine resources of the Gulf of Mannar can be enjoyed on a sustainable yield basis. In order to achieve this we need to know the existing scientific information on the Gulf of Mannar and identified gap areas where more information is to be collected. Towards this, the Gulf of Mannar Biosphere Reserve Trust’s (GOMBRT) initiative to get the present bibliography compiled by a team lead by Prof. A.K. Kumaraguru of Madurai Kamaraj University is a right step forward. Almost all scientific literature published so far, comprising nearly 3,000 publications, has been brought under one umbrella in this bibliography which will be useful not only to a number of researchers but also to administrators and managers working in the Gulf of Mannar region.

Its uniqueness and richness of bio-diversity is well acclaimed, yet it is a fragile system which cannot withstand the onslaught of ever increasing pressures and disturbances from many quarters in the coastal belt. These pressures will have to be curbed through proper understanding and acknowledging the future consequences by all the stakeholders. Scientific research is a key input in understanding our beautiful world, our natural heritage, its scope, limitations and developing options towards achieving proper, judicious and sustainable use of the fruits of natural resources for the welfare and prosperity of humankind and its progenies. Gulf of Mannar has attracted a number of scientists, researchers, agencies and institutions who have undertaken a variety of studies and surveys in the area in the past. The present publication is an attempt by the GOMBRT to facilitate compilation of the research works done in the area so far and their key findings. I place on record my deep appreciation for Dr.A.K. Kumaraguru, Professor & Director and his team from Centre for Marine and Coastal Studies, Madurai Kamaraj University for their sincere work. This will be of great help to scientists, researchers, managers and other agencies involved in the Gulf of Mannar area and will reduce undue duplication and studies of works already undertaken on various themes and issues in the area.

Coastal and marine ecosystems are extremely diverse and complex. Coral reefs, seagrass beds, mangrove enclosed seas and systems, estuaries, marshes, mud flats etc., are fragile and highly sensitive to abiotic factors. The Gulf of Mannar region along the Indian coast is a jewel in the crown of marine and coastal areas in the country and is rightly referred to as biologists’ paradise. Off late, this unique paradise is facing lot of disturbances and threats due to growing populations and their need and also because of fast growing economies. In the past, a lot of research inputs from various scientists, researchers and others have gone in the area and compilation of the outcomes of these inputs was a felt need. I am glad that the Gulf of Mannar Biosphere Reserve Trust (GOMBRT) has brought out a detailed bibliography on scientific information on the Gulf of Mannar through active involvement of the Centre for Marine and Coastal Studies, Madurai Kamaraj University. I wish to congratulate the Trust and the scientists led by Prof. A.K. Kumaraguru from Madurai Kamaraj University, who have scanned various sources to make this publication informative and intensive.

The detailed description Muricanthus kuesterianus of this species has been given with the comparison of its close resembled species Chicoreus virgineus Chicoreus virgineus. INTRODUCTION Muricidae, the largest and varied taxonomic family among marine gastropods has small to large predatory sea snails in the Order Neogastropoda. At least 1,000 species of muricids under numerous subfamilies are known. Many muricids have unusual shells which are considered attractive by shell collectors. The spire and body whorl of the muricids are often ornamental with knobs, tubercules, ribbing or spines. Muricids have episodic growth which means that the shell grows in spurts, remain- ing in the same size for a while before rapidly growing to the next size stage resulting in a series of varices on each whorl. Most species of muricids are carnivorous, feeding on other gastropods, bivalves and barnacles. In March 2007, during the course of faunistic surveys along the Palk Strait region of southeast coast of India (Fig.

The survey investigated and prioritized the communities’ needs for basic services such as water,education and health care. The survey was a co-operative effort ofthe Tamil Nadu Department ofFisheries, the Coastal Peace and DevelopmentCommittee of the Kottar Diocese, and the Bay ofBengal Programme (FAO/UN). The survey was carried out during the first half of 1998 by two local enumerators in each village selected by the Coastal Peace and Development Committee. All the enumerators were together imparted training for a day by the BOBP on the conduct of interviews, and given questionnaires. The enumerators conducted group interviews with fisherfolk of the 39 communities, both men and women, about the status of local services. This document details the findings of the survey and the comments by the respondents. It is hoped that these are founduseful by various governmentagencies and the church in improving the status of basic services and infrastructure in coastal areas of Kanniyakumari district. The survey, and this report of the survey, are part of the BOBP’s effort in co-operation with the TamilNadu Department of Fisheries to improve fisheries management in Kanniyakumari district.

    Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans

    Molecular Species Delimitation and Biogeography of Canadian Marine Planktonic Crustaceans by Robert George Young A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Integrative Biology Guelph, Ontario, Canada © Robert George Young, March, 2016 ABSTRACT MOLECULAR SPECIES DELIMITATION AND BIOGEOGRAPHY OF CANADIAN MARINE PLANKTONIC CRUSTACEANS Robert George Young Advisors: University of Guelph, 2016 Dr. Sarah Adamowicz Dr. Cathryn Abbott Zooplankton are a major component of the marine environment in both diversity and biomass and are a crucial source of nutrients for organisms at higher trophic levels. Unfortunately, marine zooplankton biodiversity is not well known because of difficult morphological identifications and lack of taxonomic experts for many groups. In addition, the large taxonomic diversity present in plankton and low sampling coverage pose challenges in obtaining a better understanding of true zooplankton diversity. Molecular identification tools, like DNA barcoding, have been successfully used to identify marine planktonic specimens to a species. However, the behaviour of methods for specimen identification and species delimitation remain untested for taxonomically diverse and widely-distributed marine zooplanktonic groups. Using Canadian marine planktonic crustacean collections, I generated a multi-gene data set including COI-5P and 18S-V4 molecular markers of morphologically-identified Copepoda and Thecostraca (Multicrustacea: Hexanauplia) species. I used this data set to assess generalities in the genetic divergence patterns and to determine if a barcode gap exists separating interspecific and intraspecific molecular divergences, which can reliably delimit specimens into species. I then used this information to evaluate the North Pacific, Arctic, and North Atlantic biogeography of marine Calanoida (Hexanauplia: Copepoda) plankton.
