The persistence of wide-ranging mammals such as Asian elephants in fragmented landscapes requires extending conservation efforts into human-dominated around protected areas. Understanding how use may help facilitate their movements and reduce conflict incidence. We studied elephants' habitats ranging patterns focal herds a landscape rainforest fragments embedded tea, coffee, Eucalyptus plantations the Anamalai Hills. Elephant entering this were tracked daily between April 2002 March 2006,...
The responses of bats to land-use change have been extensively studied in temperate zones and the neotropics, but little is known from palaeotropics. Effective conservation heavily-populated palaeotropical hotspots requires a better understanding which can cannot survive human-modified landscapes. We used catching acoustic transects examine bat assemblages Western Ghats India, identify species most sensitive agricultural change. quantified functional diversity trait filtering forest...
To conserve biodiversity it is imperative that we understand how different species respond to land use change, and determine the scales at which habitat changes affect species' persistence. We used suitability models (HSMs) spatial from 100–4000 m address these concerns for bats in Western Ghats of India, a hotspot global importance where requirements are poorly understood. acoustic capture data build fine scale HSMs ten (Hesperoptenus tickelli, Miniopterus fuliginosus, pusillus, Myotis...
ABSTRACT Changes in tree, liana, and understory plant diversity community composition five tropical rain forest fragments varying area (18–2600 ha) disturbance levels were studied on the Valparai plateau, Western Ghats. Systematic sampling using small quadrats (totaling 4 ha for trees lianas, 0.16 plants) enumerated 312 species 103 families: 1968 (144 species), 2250 lianas (60 6123 plants (108 species). Tree density, stem basal higher three larger (> 100 but negatively correlated with...
Bats play crucial roles in ecosystems, are increasingly used as bio-indicators and an important component of tropical diversity. Ecological studies conservation-oriented monitoring bats the tropics benefit from published libraries echolocation calls, which not readily available for many ecosystems. Here, we present calls 15 species Valparai plateau Anamalai Hills, southern Western Ghats India: three rhinolophids (Rhinolophus beddomei, R. rouxii (indorouxii), lepidus), one hipposiderid...
Abstract Historical fragmentation and a current annual deforestation rate of 1.2% in the Western Ghats biodiversity hotspot have resulted human‐dominated landscape plantations, agriculture, developed areas, with embedded rainforest fragments that form refuges animal corridors. On private lands Anamalai hills, India, we established restoration sites within three (5, 19, 100 ha) representing varying levels degradation such as open meadow, highly degraded dense Lantana camara invasion,...
Abstract Ecological restoration is a leading strategy for reversing biodiversity losses and enhancing terrestrial carbon sequestration in degraded tropical forests. There have been few comprehensive assessments of recovery following fragmented forest landscapes, the efficacy active versus passive (i.e., natural regeneration) remains unclear. We examined 11 indicators structure, tree diversity composition (adult sapling), aboveground storage 25 pairs actively restored ( AR ; 7–15 yr after...
It is estimated that six in every ten wild Asian elephants live India. This report by the Ministry of Environment and Forests India outlines plans to safeguard species associated habitats face rapid economic expansion development pressures.
Brown palm civet diet was assessed by examining 1,013 scats between May 1996 and December 1999 in Kalakad-Mundanthurai Tiger Reserve, Western Ghats, India. The brown is predominantly frugivorous, with fruits of 53 native species four introduced plants comprising 97% its diet. There high intra- inter-annual variation the civets. Civets adapted to fluctuations fruit resources feeding on a diverse range supplementing their year-round, primarily invertebrates vertebrates. mainly ate trees...
Abstract: The effects of fragmentation and overstorey tree diversity on regeneration were assessed in tropical rain forests the Western Ghats, India. Ninety plots sampled for saplings (1–5 cm diameter at breast height (dbh); 5×5-m plots) trees (>9.55 dbh; 20×20-m within two fragments (32 ha 18 ha) continuous forests. We tested hypotheses that expected seed-dispersal declines (1) reduce sapling densities species richness all old-growth species, increase recruitment early-successional (2)...
Abstract Forest fragmentation and habitat loss are major disruptors of plant–frugivore interactions, affecting seed dispersal altering recruitment patterns the dependent tree species. In a heterogeneous production landscape (primarily tea coffee plantations) in southern Western Ghats, India, we examined effects surrounding forest cover fruit crop size on frugivory four rainforest bird‐dispersed species ( N = 131 trees, ≥30 trees per species, observed for 623 hr). Frugivore composition...
In the Western Ghats, India, we study how different intensities of tea cultivation influence birds.We compared bird communities in conventional monoculture and mixed-shade plantations, both which use agrochemicals, with organic a rainforest fragment, continuous within Anamalai Tiger Reserve.In 225 point count surveys, overall species richness abundance were lowest up to 33% higher tea.Mixed-shade had 40% (including 15 canopy 4 shrub mid-storey speciesprimarily frugivores, nectarivores...
Conservation in human-modified landscapes is important for riparian animals as their habitats extend linearly beyond adjoining protected areas. We examined occupancy and intensity of habitat use Asian small-clawed otters coffee tea plantations an area the Western Ghats. sampled 66 stream segments 500 m length, using spraints indicator use. Several variables characterising shoreline were also measured. Occupancy, corrected detection spraints, was >0.75 all three land types, indicating...
Abstract We used capture (mist‐netting) and acoustic methods to compare the species richness, abundance, composition of a bat assemblage in different habitats Western Ghats India. In tropics, catching bats has been more commonly as survey method than recordings. our study, based on recording echolocation calls detected greater activity mist‐netting. However, some were frequently or exclusively by capture. Ideally, two should be together compensate for biases each. Using combined data, we...
Wildlife-vehicle collisions on the roads lead to mortality of a range animal taxa both within and around wildlife reserves.Quantifying understanding impacts are essential for identifying vulnerable suitable mitigation measures.We studied in relation habitat season Anamalai Tiger Reserve adjoining Valparai plateau Western Ghats, India.Habitats were broadly classified as forest, monoculture plantations (tea, coffee, eucalyptus) mixed.Eleven road transects 3-12 km length surveyed between 9 12...
The distribution and abundance patterns of Malabar Grey Hornbill Ocyceros griseus Great Buceros bicornis were studied in one undisturbed heavily altered rainforest landscape the southern Western Ghats, India. Agasthyamalai hills (Kalakad-Mundanthurai Tiger Reserve, KMTR) contained over 400 km 2 continuous rainforest, whereas Anamalai (now Indira Gandhi Wildlife Sanctuary, IGWS) fragments a matrix tea coffee plantations. A comparison point-count line transect census techniques for at site...
When leopards are found in human-dominated landscapes, conflicts may arise due to attacks on people or livestock loss when retaliate following real and perceived threats. In the plantation landscape of Valparai plateau, we studied incidents injury life over time (15 – 25 y) carried out questionnaire surveys 29 colonies eight tribal villages study correlates depredation, people's perception leopards, preferred management options for human leopard interactions. Leopards were implicated an...
