    AN ILLUSTRATED GUIDE TO THE LAND SNAILS OF THE WESTERN GHATS OF INDIA Exotic snails and slugs can be a serious problem because they are often difficult to control and can be locally about 35 Ma. The land-snail fauna of the Western Ghats and Sri Lanka reflects this complex geological history.

  • Species Diversity, Endemism and Distribution of Land Snails of the Western Ghats, India

Email: [email protected] 2 Department of Applied Zoology, Mangalore University, Mangalagangothri, Mangalore, 574199, India. 3 Malacology Centre, Poorna Prajna College, Udupi, 576 101, India. Abstract As elsewhere, invertebrate taxa have received little attention in conservation planning in India. The Western Ghats has been designated as a global biodiversity hotspot, one of only two such designations in India. We have assembled a database for land snail records in the region, incorporating both published records and the results of our own surveys over the last three years. Of the 269 species so far recorded, 75% are endemic to the region. Many species have very restricted ranges within the region. There is a decline in diversitv and local endemism from south to north. The southernmost division (8~·12°N) has much the richest recorded fauna (210 species), and the level of local endemism The latter is much lower in the central and northern divisions. There is thus considerable faunal turnover within the region. The overall level of endemism is higher than that recorded for other taxa, and our data have already been used to identify three local hotspots within the region. These results are discussed in terms of present climate and habitats, and in terms of environmental history.

MADHYASTHA* Malacology Centre, Poornaprajna College, Udupi-576 101, Karnataka, India E-mail: [email protected];[email protected]; sps [email protected] INTRODUCTION Molluscs fonn an important constituent of leaf litter and soil biota. They are an ideal group for monitoring site specific environmental impact assessment studies because of their limited migration patterns. Majority of them remain undiscovered or under described, partly because of insufficient exploration and partly because of their often minute sizes (Emberton, 1995). Unfortunately, for the last 75 years or so, in South India, no attention has been paid for this important group with exceptions of some localized reviews and publications [(Tonapi and Mulhekar, 1963; Tonapi 1971; Subba Rao and Mitra, 1979, 1986; Madhyastha et ai., 2003, 2005; Mavinkurve et ai., 2004a, (in press); Sandhya et ai., (submitted)]. The works of Ramanan (1900) and Sathyamurthi (1960) are the preliminary source for those interested in the terrestrial molluscs of Tamil Nadu. This work is in continuation of the checklist for the land snails of the southern states that is being fonnulated (Mavinkurve et al., 2004b). STUDY AREA Situated on the southeastern side of the Indian peninsula, the state of Tamil Nadu has an area of 130,058 sq Ian. The landmass of the state can be divided into two natural divisions: (i) The eastern coastal plain (ii) The hilly region along the north and the west. Along the whole length of the western part, at a distance from the sea varying from 80 to 160 km runs the Western Ghats range, a steep and rugged mass averaging 1220 metres above the sea level.

It is a UNESCO World Heritage Site and is one of the eight "hottest hotspots" of biological diversity in the world.[1][2] It is sometimes called the Great Escarpment of India.[3] The range runs north to south along the western edge of the Deccan Plateau, and separates the plateau from a narrow coastal plain, called Konkan, along the Arabian Sea. A total of thirty nine properties including national parks, wildlife sanctuaries and reserve forests were designated as world heritage sites - twenty in Kerala, ten in Karnataka, five in Tamil Nadu and four in Maharashtra.[4][5] The range starts near the border of Gujarat and Maharashtra, south of the Tapti river, and runs approximately 1,600 km (990 mi) through the states of Maharashtra, Goa, Karnataka, Kerala and Tamil Nadu ending at Kanyakumari, at the southern tip of India.

We prepared an ethogram consisting of seven states and 10 events from these observations. This is the first ethogram made for an Indian turtle species. Preliminary time-budgets suggest females may be more active than males, and our observations suggest the possibility of other sex-specific behavioral traits, although our small sample sizes prohibit statistical validation at this time. We advocate long-term behavioral studies of the Cane Turtle in its natural habitat for conservation and management purposes. Key Words.—ethogram; focal animal sampling; in-situ conservation; sex-specific behavior; terrestrial emydid; Western Ghats INTRODUCTION (Hailey and Coulson 1999). We are not aware of any time budgets for Indian chelonians in the literature.

MADHYASTHA* Malacology Centre, Poornaprajna College, Udupi-576 101, Karnataka, India E-Inail: [email protected]; [email protected]; [email protected] INTRODUCTION Tropical rainforest floor forms the workshop of diverse interactions between various organisms. The interactions in majority of the cases result in cycling of energy and nutrients. The land snails form the epigeic species i. e., those which live and feed on the soil surface. They form an important link in the recycling chain decomposing the macro litter into microforms facilitating for the action. by microorganisms. In India, especially from the Western Ghats in Karnataka, land snails have been least worked out (Madhyastha et aI., 2002; Mavinkurve et aI., 2003, 2004 a, b; in press).

    SPECIES DIVERSIFICATION IN A TROPICAL RAINFOREST LAND-SNAIL FAUNA Final Report DINARZARDE RAHEEM BELSPO Research Fellow (Non-EU Postdoc) Royal Belgian Institute of Natural Sciences, Vautierstraat 29, B-1000, Brussels 1. BACKGROUND Terrestrial biological diversity is not distributed evenly across the globe, but is concentrated in the forested tropics (Myers et al., 2000; Sechrest et al., 2002; Mittermeier et al., 2004). Our understanding of the evolutionary processes that have generated and maintained this diversity is poor, but such knowledge will be vital for conserving both the patterns and processes of diversity in the face of ongoing and future environmental change (Mace et al., 2003; Moritz & McDonald, 2005). Using land snails as a focal group and an approach centred on molecular systematics and community ecology, my 18-month fellowship aimed to investigate speciation and ecological diversification in two Sri Lankan rainforest snail genera, the pulmonate Corilla and the caenogastropod Theobaldius. In common with other taxa from other tropical rainforest regions (Moritz, et al., 2000; Hall, 2005; Weir, 2006; Brumfield & Edwards, 2007; Elias et al., 2009; Santos et al., 2009), Corilla and Theobaldius are represented by distinct species assemblages in lowland and montane rainforest. The study had two broad objectives: first, to reconstruct the evolution of these distinct lowland and montane assemblages, and second, to explore the relationship between species diversification and niche evolution. Work to date has been focussed on carrying out molecular and initial phylogenetic analyses on the two land-snail genera, Corilla and Theobaldius. In addition, I have been working on a major new taxonomic revision (Raheem et al., in press) on the land-snail fauna of the Western Ghats of India, as well two smaller related projects, one on the widespread Asian land snail Macrochlamys, and the other on the type collections of William Benson, the pioneering 19th century worker on Indian land snails.

    Ecology of two endemic turtles in the Western Ghats Final Technical Report 2010 A Radio tagged Female Cane turtle # 6 monitored during the study Principal Investigators: Karthikeyan Vasudevan and Bivash Pandav Researcher: V. Deepak Wildlife Institute of India Chandrabani, Dehradun. Citation: Vasudevan, K., Pandav, B & Deepak, V. 2010.Ecology of two endemic turtles in the Western Ghats. Final Technical Report, Wildlife Institute of India 74p. Ecology of two endemic turtles of Western Ghats EXECUTIVE SUMMARY This project was initiated on the 16th January 2006 with an aim to generate natural history information on two out of the three endemic species of terrestrial turtles. India has 28 species of freshwater turtles and tortoises, of them three species are endemic. The endemic species: Cane turtle, Vijayachelys silvatica; Travancore tortoise Indotestudo travancorica; Leith’s softshell Nilssonia leithii, are restricted to the southern peninsula and the Western Ghats. In this study the focal species were the Cane turtle and the Travancore tortoise which had their distribution in the Western Ghats. The objectives of the project were (i) to estimate the population density of Travancore tortoise and cane turtle in a fragmented landscape; (ii) to quantify the diet of these two species and describe the feeding ecology with respect to their role in seed dispersal; (iii) to identify threats to the turtle population based on their habitat use ranging pattern and food habits and recommend measures for their conservation; (iv) to carry out a survey of these two species along the Western Ghats to ascertain the exact distribution in the context of Protected area network in the region.
