Résumé :

AbstractThe Vulnerable bumphead parrotfish Bolbometopon muricatum, a highly prized fishery resource worldwide, has experienced population declines throughout its geographical range. There is limited knowledge of the distribution and abundance of, and threats to, this fish in Indian waters, particularly for the Andaman and Nicobar Islands. To assess the species’ distribution and conservation status we conducted underwater surveys across 75 sites around 51 islands and interviewed 99 fishers across the Andaman and Nicobar archipelago. We recorded a total of 59 individual B. muricatum across nine sites from the northernmost island in the Andamans (Landfall Island) to the southernmost island in the Nicobars (Great Nicobar Island). Interviews revealed that most fishers (100% in Nicobar, 94% in Middle Andaman, 62% in South Andaman) had seen B. muricatum, and knowledge of the species is highest amongst spearfishers. Generalized linear models indicated that presence of marine protected areas and high live coral cover influenced the abundance and distribution of B. muricatum. The species' density seems to be naturally low in the archipelago. We discuss our findings in the light of protecting rare and threatened species, and recommend strengthening the existing marine protected areas in these islands.

Résumé :

Andaman and Nicobar Islands have two different genetic groups of cattle namely Andaman local cattle and Trinket cattle. Andaman local cattle are distributed in Andaman group of Islands and Campbell Bay of Nicobar group of Islands. Andaman local cattle are non-descriptive and represent an admixture of different Indian breeds that had been brought to these islands in different phases of inhabitation and rehabilitation of migrated people. It is believed that the Andaman local cattle have the inheritance from Red Sindhi, Sahiwal and Hariana. It is unique cattle, well adapted to special type of tropical humid island climatic and environmental condition. The present study was designed to standardise the normal reference haematological and biochemical range for different age groups of Andaman local cattle which were maintained in the South Andaman and North and Middle Andaman district, Andaman and Nicobar Islands, India. In this study, haematological parameters, biochemical indices and antioxidant and oxidative stress profiles were estimated in healthy, normal physiological Andaman local cattle for different age groups. The present study results clearly indicated that the values of haematological, biochemical and antioxidant profiles were under the normal physiological range. These results of this study may serve as the reference values in which alterations due to metabolic, nutrient deficiency, physiological and health status can be compared for diagnostic and therapeutic purposes for Andaman local cattle in Andaman and Nicobar Islands and its neighbouring countries or other parts of the country with similar environmental and climatic conditions.

Résumé :

The damage sustained by buildings and structures in the Andaman and Nicobar islands area was due to earthquake shaking and/or giant tsunami waves. While damage on Little Andaman Island and all the Nicobar Islands was predominantly tsunami-related, damage on islands north of Little Andaman Island was primarily due to earthquake shaking even though tsunami waves and high tides were also a concern. In general, the building stock consists of a large number of traditional and non-engineered structures. Many traditional structures are made of wood, and they performed well under the intensity-VII earthquake shaking sustained along the islands. However, a number of new reinforced concrete (RC) structures suffered severe damage or even collapse. Also, extensive damage occurred to the coastal and harbor structures in the Andaman and Nicobar islands.

Résumé :

The paper explores the key factors relevant to the development of micro and small businesses in the Andaman and Nicobar Islands. This study specifically focused on the relevant factors from the islands' perspectives. This study used primary sources of data collected in the South Andaman Islands (Andaman and Nicobar Islands), and the obtained data were analyzed using SPSS. The findings of the study proved that tourism business and marine and wood-based businesses have huge potential in the Andaman Islands. The study's findings highlighted the significance of subsidies and incentives for island promotion and sustainable development, which could be accomplished through capital investment, as well as transportation subsidies, which are critical for new and existing businesses on islands. Cargo transportation from the mainland to islands is the primary mode of sea transportation and the only mode between island regions. Under this situation, the Andaman and Nicobar Islands totally rely on manufacturing or service businesses as a lifeline. Hence, micro- and small businesses will play a vital role in employment generation, production, investments, and the growth of a small business. As a result, the administration of the islands should implement appropriate policy measures based on the relevant factors in the islands' region. The local administration needs to support and provide easy access to finance, transportation, and other facilities for small businesses in the Andaman and Nicobar Islands.

Journal of Threatened Taxa 14, n^o 1 (26 janvier 2022) : 20406–12. http://dx.doi.org/10.11609/jott.7719.14.1.20406-20412.

Texte intégral

Résumé :

Halophila beccarii, listed as ‘Vulnerable’ on the IUCN Red List, aids in seagrass and mangrove succession, acts as a substrate stabilizer and provides feeding grounds for mega-herbivores like dugongs. This species was first recorded from the Andaman & Nicobar Islands in 2015, and its distribution status within the archipelago remains under-investigated. We report a new distribution record of H. beccarii from the North Andamans and shed light on its inter-island distribution. H. beccarii was recorded from a mixed meadow comprising of Cymodocea rotundata (20.5 ± 28.8%, mean seagrass cover), Thalassia hemprichii (16.3 ± 23.3%, mean seagrass cover), and Halodule pinifolia (6.3 ± 12.1%, mean seagrass cover) at Pokkadera, North and Middle Andaman district. H. beccarii had the highest mean seagrass cover (30 ± 34.7%) and shoot density (103.5 ± 68.3 shoots/ m2) among sympatric seagrass species. We also recorded eight seagrass-associated macrofaunal groups (gastropods, bivalves, polychaetes, foraminiferans, nematodes, brachyurans, decapods and asteroids) from the infaunal and epibenthic micro-habitats within the meadow. Infaunal macrobenthos had a much higher density (73.5 ± 129.7 individuals/m2) than the epibenthic macrofauna (0.4 ± 1.5 individuals/m2), possibly influenced by the seagrass canopy structure and biomass. Overall, gastropods were the most dominant macrobenthic faunal group (overall mean 95.0 ± 106.1 individuals/m2). The present findings emphasize the need for more exploratory surveys to understand H. beccarii distribution in the Andaman & Nicobar archipelago to identify priority conservation areas.

Résumé :

Background: In Andaman and Nicobar Islands, there is very limited study that provides information on different aspects of hearing loss and even data that indicates the prevalence of hearing loss is limited. This study aims to descriptively analyses different aspects of hearing loss and also estimate the prevalence of hearing loss in Andaman and Nicobar Islands. Material and Method: Andaman and Nicobar Islands have only one ENT and Audiology setup which is located in Port Blair, at G. B. Pant Hospital. Any disorders and diseases related to hearing loss were referred and or one has to attend the only hospital from every corner of the Islands. A retrospective and descriptive analysis was conducted for a total of 7021 cases who were referred for Audiological diagnosis during 2018 to 2019, before the Coronavirus pandemic. A descriptive analysis was done for different types and degree of hearing loss. The Prevalence of Hearing Loss for various types and degree of hearing loss, and their correlation with gender and age was estimated. Results: Par degree of Hearing Impairment, of 7021 sample, the overall estimated prevalence of Hearing Impairment (HI) was 41.74%. Mild degree of HI (18.13%) was most prevalent and Profound HI (1.6%) was least prevalent. For type of Hearing loss, Bilateral SNHL (10.7%) was most prevalent and B/L Mixed HL (3.4%) was least prevalent. The prevalence of Unilateral CHL (10.06%) was surprisingly higher than other unilateral conditions. Par age, the prevalence of hearing loss was most significant among 14-50 age group. Par gender, results shows more prevalence in males than females. Conclusion: The estimated high prevalence of hearing loss will have negative impact in Andaman and Nicobar Islands. Health education, adequate manpower, systematic awareness plan in rural and among socio – economically deprived is an eminent requirement in order to reduce the burden of hearing loss. Key words: Prevalence, HI: Hearing Impairment, HL: Hearing Loss, SSD: Single Sided Deafness, Andaman and Nicobar Islands (A & N Islands), Port Blair. PTA: Puretone Audiometry.

Résumé :

Six Indo-Pacific sponges are recorded for the first time from the Andaman and Nicobar Islands: Agelas ceylonica sensu Thomas, 1981, Axinella donnani (Bowerbank, 1873), Dragmacidon australe (Bergquist, 1970), Siphonodictyon maldiviense (Calcinai, Cerrano, Sarà & Bavestrello, 2000), Clathrina clara Klautau & Valentine, 2003 and Plakortis bergquistae Muricy, 2011. Among them, D. australe, S. maldiviense and P. bergquistae are indeed new records to India. These findings not only represent new additions to sponge fauna of India, but also highlight the importance of markedly overlooked sponge diversity of the Andaman and Nicobar Islands.

Résumé :

Abstract Ascidians are filter-feeding sac-like marine urochordates of great evolutionary, ecological and economic importance. Andaman and Nicobar Islands are one of the most important hot spots of biodiversity in India, while the ascidian diversity of this region is very scanty. Ascidians belonging to 29 species were identified at the Andaman and Nicobar Islands during the field research carried out from March 2014 to April 2015. Eight species (Didemnum granulatum, Didemnum molle, Didemnum psammatodes, Diplosoma listerianum, Lissoclinum fragile, Lissoclinum levitum, Lissoclinum patella, Trididemnum Cyclops) from the Didemnidae family were found and identified. Various diversity indices, such as the Shannon -Wiener index (H’), Margalef’s index (D), Pielou’s index (J’), K-dominance curves, Cluster Analysis and Multidimensional Scaling, were used to analyze the diversity, richness and evenness of species, and to compare the diversity between samples and their resemblance in terms of species composition. The maximum species richness was observed in Campbell Bay (2.424) and the minimum in Haddo Wharf (0.910). This finding shows the rich species diversity of ascidian fauna at Andaman and Nicobar Islands.

Résumé :

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.

Résumé :

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.

Résumé :

Takahashi (1942) described Dialeurotrachelus cambodiensis, the type species of the monotypic whitefly genus, Dialeurotrachelus Takahashi from three syntype specimens collected on an unidentified tree in Cambodia, which were subsequently lost or destroyed. It was rediscovered after eight decades in the Indian territories of the Andaman and Nicobar Islands. A neotype is designated for D. cambodiensis Takahashi, from specimens collected on Diospyros kurzii Hiern (Ebenaceae) from Andaman Island, India. It is recorded for the first time from the Indian territories, Andaman and Nicobar Islands. Pupal morphology is assessed for redefining the generic description with differential diagnoses from related genera, and anomalies involved with structure of the vasiform orifice and associated structures are discussed. Illustrations are provided of the puparia in life, camera lucida drawings, slide mounts, and scanning electron photomicrographs.
