AbstractDuring a biodiversity assessment on an upper mesophotic artificial reef of Andaman and Nicobar Islands (Shipwreck: HMIS Sophie Marie/HMIS SM), a single specimen of sponge Chelonaplysilla delicata was recorded. Our finding confirms the species taxonomy and highlights the current observation as a first report from the Andaman and Nicobar Islands and the Indian Ocean. The baseline diversity of epifaunal assemblage is further reported in this study.

The growing strategic importance of Andaman and Nicobar Islands is now changing the dynamics of Indian ocean and maritime politics. The sea politics is now has been more tangled than before. Viewed under the theory of offensive realism proposed by John Mearsheimer that holds the concept of power maximization of states and balancing strategies to counter their rival states as all states have some offensive capabilities and countries can never be certain about the intentions of other states. The ultimate goal is to dominate. Within that context, the study aims to examine the growing strategic importance of Andaman and Nicobar Islands and its future prospects and implications on Pakistan. This paper analyzes the main indicators that India is presently working on, to develop its Tri-service theatre. The study seeks to answer the following questions a) How Andaman and Nicobar Islands are strategically important for India? b) How will the development of the two islands will change the dynamics of maritime politics and tackle increasing Chinese presence in Indian ocean? c) What will be the future implications or Pakistan? The study argues that the ANC is the significant factor for India to aggravate its control in the Indian Ocean region as it is developing its largest military and nuclear build-up. However, it can unleash negative imprints for Pakistan in future in certain aspects.

Boats and ships are the major modes of transportation among the Andaman and Nicobar group of islands. The Andaman Trunk Road also forms an important part of the transportation system in the Andaman Islands north of Port Blair. The harbor structures in the islands were the most affected during the ground shaking; the result heavily disrupted the lives of the island residents. These transportation systems are expected to be in working condition after a major disaster, to facilitate the search and rescue operations and the relief work in the affected areas. A reconnaissance team surveyed the damage that the 2004 earthquake and tsunami caused to the transportation structures in the islands. Damage was observed in all transportation systems, including harbors, highways, airports, and hangars.

AbstractInformation on the bat fauna of the Andaman and Nicobar Islands was limited previously to the results of sporadic surveys, with no specific focus on the habitats or distribution of the species. We carried out the first extensive survey of the Andaman and Nicobar Islands during 2003–2006, covering 40 islands. Our objective was to map the bat species, their habitats and distribution. This resulted in identification of 25 bat species representing 13 genera, location of > 300 roosts and validation of previously recorded species. Notable findings included the rediscovery of the endemic Nicobar flying fox Pteropus faunulus after a century and its extinction from the type locality on Car Nicobar Island, the sighting of an albino Hipposideros diadema nicobarensis from Katchal Island, and the first records of Rhinolophus yunanensis, Murina cyclotis and Hipposideros larvatus from the Andaman Islands, and Taphozous melanopogon, Murina cyclotis, Pipistrellus spp., Myotis horsfieldii dryas and Cynopterus brachyotis from the Nicobar Islands. Threats to the bat fauna appear to be primarily roost disturbance and hunting for sport. Anthropogenic pressure on species of Pteropus is high as hunting occurs throughout the year. Secondary sources and our field observations confirmed the decline of Pteropus in several islands as a result of hunting and alteration to habitats. We introduced a community initiative to monitor and protect roosts and foraging sites close to settlements in the Nicobar Islands. Priorities identified for conservation of the bat fauna of the archipelagos are mitigation of threats to flying foxes and cave dwelling bats, initiation of research on endemic bat species such as P. faunulus, and a voluntary ban by local communities on hunting in specific areas and seasons.

Plate tectonics after the 26 December 2004 Great Sumatra earthquake resulted in major topological changes in the Andaman and Nicobar islands. Aerial and land reconnaissance surveys of those islands after the earthquake provide evidence of spectacular plate tectonics that took place during the earthquake. Initial submergence of the built environment and the subsequent inundation upon arrival of the tsunami wave, as well as emergence of the new beaches along the islands—particularly on the western rims of the islands and in the northern islands—are the major signatures of this Mw=9.3 event.

<p><em>Paracyathus pruinosus</em> Alcock, 1902, (Scleractinia: Caryophylliidae) was found from Andaman and Nicobar Islands, representing a new addition to the ahermatypic corals of India and the central Indian Ocean. The corallites of <em>Paracyathus pruinosus</em> were solitary, short, stout, elliptical and solid, mostly found under caves and slightly deep. Costae were granular, flat and equal. Septa were arranged closely and lined with granular ridges. Tentacles were found to extend only during night. The present record of <em>P. pruinosus </em>from Andaman and Nicobar Islands not only represents a new addition to the Caryophylliidae of the Central Indian Ocean, but also calls for conducting in-depth studies with a special emphasis to the under-studied caryophylliids of India.</p><div> </div>

A New Species

The systematic position of the agamid genus Coryphophylax (Squamata: Agamidae) is given as monotypic and endemicto the Andaman and Nicobar Islands in the Bay of Bengal, India. After having surveyed intensively in thirteen differentIslands and examined several individuals in the Andamans group of islands, we describe a second species ofCoryphophylax from the lowland rainforests of the South Andaman Island. Coryphophylax brevicaudus sp. nov. isdifferentiated from its congener, C. subcristatus (Blyth, “1860” 1861) by its smaller size, relatively shorter tail, presenceof nuchal and dorsal crests in both sexes, midbody scale row counts and colour pattern. The new species lives in sympatrywith C. subcristatus. The taxonomic history and systematic status of the genus Coryphophylax are discussed, and the need for continued surveys in the Islands is emphasized.
