“…Each fruit typically contains two seeds (coffee beans). Coffee seeds are known to be dispersed by mammals; in the study area the main dispersers of coffee are the brown palm civet Paradoxurus jerdoni, Asian elephant Elephas maximus, lion-tailed macaque Macaca silenus, and sloth bear Melursus ursinus (Mudappa 2001;Muthuramkumar et al 2006). …”

“…In other sites, the density of the coffee species (C. arabica and C. canephora) cultivated in the adjoining plantation declined sharply from the edge of the plantation up to 100 m inside the fragment; beyond this threshold, coffee density is low and does not change substantially further into the interior. The geographical range of seed dispersal by animals is definitely larger than 100 m. For example, the home range of brown palm civet (Paradoxurus jerdoni) is between 6 and 57 ha (Mudappa 2001), and that of primates and elephants even larger. Another factor that may significantly influence the spread of coffee and its decline in density from the edge is propagule pressure from the forestplantation boundary directly due to proximity to fruit-bearing crop plants.…”

While the conservation impacts of invasive plant species on tropical biodiversity is widely recognised, little is known of the potential for cultivated crops turning invasive in tropical forest regions. In the Western Ghats biodiversity hotspot, India, fragmented rainforests often adjoin coffee plantations. This study in the Anamalai hills assessed the effects of distance from edges and forest structure on the occurrence and abundance of shade-tolerant coffee (Arabica Coffea arabica and Robusta C. canephora) in four fragments (32-200 ha) using replicate line transects laid from the edges into the interiors. The coffee species cultivated in adjoining plantations was more abundant than the other coffee species inside study fragments, showing a clear decline in stem density from edge (0 m) to interior (250 m), suggesting the influence of propagule pressure of adjoining plantations, coupled with edge effects and seed dispersal by animals. Significant positive correlations of coffee density with canopy cover indicate the potential threat of coffee invasion even in closed canopy rainforests. Stem density of Coffea arabica (150-1,825 stems/ha) was higher in more disturbed fragments, whereas Coffea canephora had spread in disturbed and undisturbed sites achieving much higher densities (6.3-11,486 stems/ha). In addition, a negative relationship between C. canephora and native shrub density indicates its potential detrimental effects on native plants.

“…Very limited information was available on the distribution of the brown palm civet until recent surveys revealed that the species occurs widely along the Western Ghats from around 8° N to about 15° 20' N but is restricted to tropical rainforest vegetation [22], including in fragmented landscapes [23]. Still, research on the ecology of the brown palm civet has been scarce [10] and the present study is the first detailed report on the diet of the species. The study addressed the following questions: (a) What is the diversity of species or food items consumed by the brown palm civet?…”

Brown palm civet diet was assessed by examining 1,013 scats between May 1996 and December 1999 in KalakadMundanthurai Tiger Reserve, Western Ghats, India. The brown palm civet is predominantly frugivorous, with fruits of 53 native species and four species of introduced plants comprising 97% of its diet. There was high intra-and inter-annual variation in the diet of brown palm civets. Civets adapted to fluctuations in fruit resources by feeding on a diverse range of species and supplementing their year-round, primarily frugivorous, diet with invertebrates and vertebrates. Civets mainly ate fruits of trees and lianas, rarely those of herbs or shrubs. Fruits eaten by civets were mostly small (<1 cm diameter), multiseeded, pulpy berries, and drupes with moderate to high water content, along with several large (>2 cm) fruits like Palaquium ellipticum, Elaeocarpus serratus, Holigarna nigra, and Knema attenuata. The brown palm civet is a key mammalian seed disperser in the Western Ghats rainforest by being predominantly frugivorous and dispersing a diverse array of plant species. As brown palm civets can persist in fragmented rainforest, they can play a major role in restoration of degraded fragments in these landscapes. The results emphasize the need to recognize the importance of small carnivores as seed dispersers in tropical forests.

“…Habitat utilization of various mammalian orders has been reported to be mainly influenced by food resources and/or predation pressure (e.g. Primates: Clutton-Brock, 1975;van Schaik et al, 1996;Koenig, 2000, Cetartiodactyla: Teng et al, 2004Brodie and Brockelman, 2009, Perissodactyla: Fischhoff et al, 2007, and Carnivora: Buskirk and Powell, 1994Miyoshi and Higashi, 2005;Mudappa, 2006). On the basis of a review of these literatures, animals select habitats that are optimal with respect to food availability and predation avoidance, though other factors such as the weather (i.e., temperature, rainfall) and the social system occasionally influence habitat selection.…”

Riverine refuging by proboscis monkeys (Nasalis larvatus) and sympatric primates: Implications for adaptive benefits of the riverine habitat

2011

a b s t r a c tRiverine refuging by non-human primates, with focus on proboscis monkeys, was studied in a forest along the Menanggul River, Sabah, Malaysia from May 2005 to 2006. The results of the primate census indicated that not only proboscis monkeys but also sympatric primates inhabiting the study site preferred to utilize the riverine habitat for night-time sleeping, though the frequency of riverine usage was different among these sympatric primates. Four predation-related events in the study site and two additional predation reports at other study sites involving clouded leopards suggest a relatively high predation pressure in proboscis monkeys relative to other sympatric primates. Riverine refuging, which represents a strategy of long-range visibility, may provide non-human primates including proboscis monkeys with the common benefit of an effective means of predation avoidance. In addition, a one-male group of proboscis monkeys was studied to clarify the effects of food availability and air temperature on riverine refuging. Proboscis monkeys spent more time in the inland habitat, though the food availability was not much different between riverine and inland habitats, indicating that food availability is not a fundamental factor in their preference for riverine habitat. Air temperature only had a small effect on their preference for the riverine habitat. However, to clarify the reasons why riverine refuging is more common in proboscis monkeys than in sympatric primates, further investigation is needed.
