Diet of the Common Palm Civet Paradoxurus Hermaphroditus in a Rural Habitat in Kerala, India, and Its Possible Role in Seed Dispersal Diet of the Common Palm Civet Paradoxurus hermaphroditus in a rural habitat in Kerala, India, and its possible role in seed dispersal Abstract P. S. JOTHISH Paradoxurus hermaphroditus Common Palm Civet diet in a rural habitat in India was studied by faecal analysis. Observations were made from January 2008 to May 2010, although no faeces wereCarica found papaya after January was the 2010. most In common total 94 fruitfaeces of werewhich collected. remains Of these, vegetable matter alone was found in 82% and animal matter alone in 4%; 14% held both plant and animal matter. Fruits were the predominant vegetable matter in the faeces. Papaya were found and was eaten year round. No seasonal change in proportion or dietary shift between vegetable and animal matter- was observed. Seeds from faeces were viable and a high percentage of defecated seeds germinated. Considering the movement pattern of Common Palm Civets studied elsewhere and the high seed germination rate, Common Palm Civet is plausibly an ef fective seed disperser of fleshy-fruited plants in the study area. Common Palm Civet often attacks poultry and is perceived as a Keywordsthreat by the poultry farmers. : Balaramapuram, faecal analysis, frugivory, poultry raiding, seed germination Introduction Methods - - Order Carnivora includes a wide range of animals character Food composition was studied by analysing faeces, a technique ised by a diversity of diets.

Wesley-Hunt1, Reihaneh Dehghani2,3 and Lars Werdelin3 1Biology Department, Montgomery College, 51 Mannakee St. Rockville, Md. 20850, USA; 2Department of Zoology, Stockholm University, SE-106 91, Stockholm, Sweden; 3Department of Palaeozoology, Swedish Museum of Natural History, Box 50007, SE-104 05, Stockholm, Sweden INTRODUCTION Ecological morphology (ecomorphology) is a powerful tool for exploring diversity, ecology and evolution in concert (Wainwright, 1994, and references therein). Alpha taxonomy and diversity measures based on taxon counting are the most commonly used tools for understanding long-term evolutionary patterns and provide the foundation for all other biological studies above the organismal level. However, this provides insight into only a single dimension of a multidimensional system. As a complement, ecomorphology allows us to describe the diversification and evolution of organisms in terms of their morphology and ecological role. This is accomplished by using quantitative and semi-quantitative characterization of features of organisms that are important, for example, in niche partitioning or resource utilization. In this context, diversity is commonly referred to as disparity (Foote, 1993). The process of speciation, for example, can be better understood and hypotheses more rigorously tested, if it can be quantitatively demonstrated whether a new species looks very similar to the original taxon or whether its morphology has changed in a specific direction. For example, if a new species of herbivore evolves with increased grinding area in the cheek dentition, it can either occupy the same area of morphospace as previously existing species, suggesting increased resource competition, or it can occupy an area of morphospace that had previously been empty, suggesting evolution into a new niche.

They differ from each other by their furs and body sizes and both are threatened with extinction (Nowak, 1991; Corbet & Hill 1992). Bears have relatively undeveloped carnassial teeth; narrow premolars, crushing molars with flat crowns and large robust canines. 127 3.4.1.1 Subfamily Ursinae Fischer, 1817, Plate 3(A1 to B3) As mentioned above, two genera and two species represent the subfamily Ursinae in Southeast Asia, namely: - Malayan Sun Bear (Figure 3.8, A), Ursus/Helarctos malayanus (Raffles, 1821) with the scientific name Ursu and synonym Helarctos is distributed in the south west of China, Assam, Myanmar, Vietnam, Peninsular Malaysia, to the islands of Sumatra and Borneo. It is the smallest of all bears found in the tropical rainforests of Southeast Asia. - Asiatic Black Bear (Figure 3.8, B), Ursus thibetanus Cuvier, 1823 is mainly localized in the Himalayas, Afghanistan to southern China, Myanmar, northern Thailand and Indochina. It has several alternative names including Asiatic Black Bear, Himalayan Black Bear, Moon Bear and inhabits mountain forests.

  • The 2008 IUCN Red Listings of the World's Small Carnivores
    The 2008 IUCN red listings of the world’s small carnivores Jan SCHIPPER¹*, Michael HOFFMANN¹, J. W. DUCKWORTH² and James CONROY³ Abstract The global conservation status of all the world’s mammals was assessed for the 2008 IUCN Red List. Of the 165 species of small carni- vores recognised during the process, two are Extinct (EX), one is Critically Endangered (CR), ten are Endangered (EN), 22 Vulnerable (VU), ten Near Threatened (NT), 15 Data Deficient (DD) and 105 Least Concern. Thus, 22% of the species for which a category was assigned other than DD were assessed as threatened (i.e. CR, EN or VU), as against 25% for mammals as a whole. Among otters, seven (58%) of the 12 species for which a category was assigned were identified as threatened. This reflects their attachment to rivers and other waterbodies, and heavy trade-driven hunting. The IUCN Red List species accounts are living documents to be updated annually, and further information to refine listings is welcome.

The sighted species included Leopard Cat, Rustyspotted Cat, Jungle Cat, Small Indian Civet, Asian Palm Civet, Brown Palm Civet, Common Mongoose, Ruddy Mongoose, Stripe-necked Mongoose and unidentified species of Otters. Malabar Civet, Fishing Cat, Brown Mongoose, Nilgiri Marten, and Ratel were not sighted during this study. The Western Ghats alone account for thirteen species of small carnivores of which six are endemic. The sighting of Rustyspotted Cat is the first report from Karnataka. Habitat loss and hunting are the major threats for the small carnivore survival in nature. The Small Indian Civet is exploited for commercial purpose. Hunting technique varies from guns to specially devised traps, and hunting of all the small carnivore species is common in the State.

    Characteristics of the complete mitochondrial genome of the monotypic genus Arctictis (Family: Viverridae) and its phylogenetic implications Siuli Mitra1,*, Vaishnavi Kunteepuram1,*, Klaus-Peter Koepfli2, Neha Mehra1, Wajeeda Tabasum1, Ara Sreenivas1 and Ajay Gaur1 1 Laboratory for Conservation of Endangered Species (LaCONES), CSIR-Centre for Cellular and Molecular Biology, Hyderabad, Telangana, India 2 Center for Species Survival, Smithsonian Conservation Biology Institute, Washington, D.C., USA * These authors contributed equally to this work. ABSTRACT The binturong (Arctictis binturong) is classified as a member of the subfamily Para- doxurinae within the family Viverridae (Carnivora: Mammalia) and comprises nine subspecies spread across Southern and Southeast Asia. Here, we describe the complete mitochondrial genome of the Indian subspecies A. b. albifrons using next-generation sequencing methods. The total length of the A. b. albifrons mitogenome was 16,642 bp. Phylogenetic analyses based on 13 mitochondrial protein-coding genes placed the binturong as a sister taxon to Paguma larvata within the Paradoxurinae and supported the clustering of Genettinae and Viverrinae and the monophyly of Viverridae and six other families of feliforms, consistent with previous studies. Divergence time estimates suggest that the Viverridae diversified during the Miocene (22.62 Mya: 95% CI [20.78– 24.54] Mya) and that Arctictis and Paguma split 12.57 Mya (95% CI [8.66–15.67] Mya).

Flying squirrels consumed 4 major plant parts belonging to 9 plant species. Ficus racemosa was the most-eaten species (68.1%) during the period of the study, followed by Cullenia exarillata (9.57%) and Artocarpus heterophyllus (6.38%). The most commonly consumed food item was the fruit of F. racemosa (48.93%). Leaves formed an important component of the diet (32.97%) and the leaves of F. racemosa were consumed more than those of any other species. Flying squirrels proved to be tolerant of disturbance and exploited food resources at the fragment edge, including exotic planted species. Key words: edge, Ficus, fig fruits, folivore, Petaurista philippensis, rain-forest fragment, Western Ghats The adaptability of mammals allows them to exist in varied across the Western Ghats seem to increase with disturbance. environments and helps them to cope with habitat fragmenta- Ashraf et al.
