Abstract Old World fruit bats (family Pteropodidae) are common throughout the Paleotropics, where they play an important ecological role as seed dispersers and pollinators. Although many regions host diverse assemblages of fruit bats, mechanisms of resource partitioning are only beginning to be documented. This study investigates the potential role of feeding behavior in patterns of resource use within a sympatric assemblage of pteropodids from Papua New Guinea. Individuals of Syconycteris… Expand
Seed predation by the wrinkle-faced bat Centurio senex: a new case of this unusual feeding strategy in Chiroptera
TLDR
It is shown that endocarp hardness has important implications on the ecological interaction between C. senex and S. capiri, due to the bats inability to puncture seeds with harder endocarps, causing an alternation between predation and dispersal of seeds. Expand
Dietary variation in spectacled flying foxes (Pteropus conspicillatus) of the Australian Wet Tropics
TLDR
The diet of Pteropus conspicillatus, a large flying fox, was examined by collecting faeces in traps beneath daytime roost trees in four geographically distinct camps in the Wet Tropics bioregion of North-eastern Queensland, Australia to suggest that camps may need to be managed on an individual camp-specific basis. Expand
Rousettus madagascariensis (Chiroptera: Pteropodidae) shows a preference for native and commercially unimportant fruits
TLDR
It is suggested that maintaining natural food availability in humid forests and providing alternative sources of fruit may contribute to limiting the damage caused by R. madagas- cariensis to commercially important crops. Expand
MORPHOLOGICAL AND ECOLOGICAL CORRELATES OF COEXISTENCE IN MALAYSIAN FRUIT BATS (CHIROPTERA: PTEROPODIDAE)
TLDR
It is suggested that relatively minor separation among Cynopterus species pairs along single axes of resource use is sufficient to counteract overlap on other axes, and permit the coexistence of potential competitors. Expand
In situ feeding tactics of short-nosed fruit bat (Cynopterus sphinx) on mango fruits: evidence of extractive foraging in a flying mammal
TLDR
It appears that actions exhibited by C. sphinx in peeling off the outer skin of mangoes exemplify “extractive foraging”, a behavior that is prominently known in large-brained mammals. Expand
Ecomorphological analysis of the masticatory apparatus in the seed-eating bats, genus Chiroderma (Chiroptera: Phyllostomidae)
TLDR
It is revealed that the pattern of morphological differentiation that emerged from the canonical variate analysis does not agree with the one expected based solely on the phylogenetic relationships adopted for the canopy fruit-bats studied here, which is consistent with the hypothesis that morphological adaptations related to granivory have evolved in Chiroderma. Expand
The Role of Frugivorous Bats in Tropical Forest Succession
TLDR
It is suggested that frugivorous New World phyllostomid bats play a more important role in early plant succession than their Old World pteropodid counterparts, and fruit‐eating bats play important roles in forest regeneration throughout the tropics, making their conservation highly desirable. Expand
Aspects of digestion and physiology in Wahlberg's epauletted fruit bat (Epomophorus wahlbergi)
TLDR
The results of this study showed that the morphological structures of tongue papillae in E. wahlbergi were similar to that of other fruit and nectar feeding bats and showed morphological adaptations for efficiently feeding on fleshy fruit andNectar. Expand
Diversity of fruit bats (Pteropodidae) and their ectoparasites in Batuputih Nature Tourism Park, Sulawesi, Indonesia
TLDR
Nycteribiidae was the most abundant ectoparasite taxa while the highest mean abundance and intensity were observed for the genus Thoopterus and Rousettus, which provides important baseline data for future reference in monitoring bat population status and conservation efforts in the region. Expand
Age and food hardness affect food handling by insectivorous bats
TLDR
Feeding behaviour of insectivorous bats eating hard and soft mealworm-based food items is quantified based on the bats’ ability to consume and manipulate food items, consumption time, chew frequency, and total chews to consume. Expand

The effect of food hardness on feeding behaviour in frugivorous bats (Phyllostomidae): an experimental study
TLDR
Results of chi-square, log-linear, R×C, and Kruskal–Wallis tests demonstrate that feeding behaviours vary significantly with fruit hardness both within and between species. Expand
Food habits of Cynopterus brachyotis (Muller) (Chiroptera: Pteropodidae) in Peninsular Malaysia
TLDR
It is suggested that folivory (by leaf fractionation) should be energetically more advantageous than the ingestion of large amounts of low protein fruit or the active pursuit of mobile insects. Expand

TLDR
Investigating the diets and patterns of coexistence in this group of ecologically similar species of anurans at the Río Llullapichis in Amazonian Perú finds similarity in diet within guilds tends to be lowest in the dry season when food is less abundant, suggesting that food is in short supply in thedry season.

Bats, flowers and fruit: evolutionary relationships in the Old World
TLDR
Old World phytophagous bats (Megachiroptera: Pteropodidae) number 173 species of which 79% are Asian and 21% African, and both bat-flower and bat-fruit syndromes are commonly recognized. Expand
Old World fruit bats can be long–distance seed dispersers through extended retention of viable seeds in the gut
TLDR
It is demonstrated regular daytime (>12 hours) retention of food and viable fig seeds in the gut of the Old World fruit bat Cynopterus sphinx: a behaviour not previously reported for any frugivorous bat. Expand
Vertical stratification of fruit bats (Pteropodidae) in lowland dipterocarp rainforest in Malaysia
TLDR
The abundance of Old World fruit bats in the subcanopy indicates that their roles in pollination and seed dispersal of Malaysian forest trees may be greater than previously recognized. Expand
Hardness as a basis of fruit choice in two sympatric primates.
TLDR
It is demonstrated that hardness of both fruit pericarp and seed may play a significant role in food choice among sympatric vertebrates and in studies of mammalian foraging behavior. Expand
Roosting and Foraging Behavior of the Queensland Tube-Nosed Bat, Nyctimene-Robinsoni (Pteropodidae) - Preliminary Radio-Tracking Observations
TLDR
The high density of fruiting cluster fig trees in November and December could account for the sedentary behaviour ot this bat at this time of year. Expand
Ecomorphological analysis of trophic niche partitioning in a tropical savannah bat community
TLDR
Comparisons of three species with highly specialized feeding habits with the rest of the species in the community indicate that specialization into these niches comes at the expense of bite performance and, hence, may result in a reduction of the trophic niche breadth. Expand
Preferences of fig wasps and fruit bats for figs of functionally dioecious Ficus pungens
TLDR
The interaction between figs, pollinators and frugivores introduces the potential for conflict between the roles of raising fig wasps and dispersing seeds, which could compromise pollination mutualism. Expand
