Abstract:The floral biology and pollination ecology of durian, Durio zibethinus, were determined in eight semi-wild trees in mixed-fruit orchards in southern Thailand during April-May 2003 and 2005. Flowers open fully at 16h00–16h30 and most androecia drop around 01h00. Anthers dehisce at 19h30–20h00 when the stigmata are already receptive. In a series of pollination experiments, fruit was set in all treatments within 10 d. The greatest pollination success occurred after hand-crossed (76.6%), open (54.4%) and emasculation pollination (53.3%). Consistently, hand-crossed (12.2%), emasculation (8.7%) and open pollination (5.1%) yielded a substantial fruit set 2 mo after the pollination experiments. Very low pollination success in facilitated autogamy suggests that most durian trees are highly self incompatible. No mature fruit was found after insect pollination and automatic autogamy. Fruit bats, especially Eonycteris spelaea, are the major pollinators of this durian although the giant honey bee (Apis dorsata) was the most frequent visitor to the flowers. Bats visited durian flowers at the rate of 26.1 (SD = 20.7) visits per inflorescence per night. Since this semi-wild durian depends on fruit bats as its pollinator, protecting fruit bat populations and their roosts is vital for the production of the durian fruit crop.

1. The effect of cobalamin inactivation by the anaesthetic gas nitrous oxide on the concentration of S-adenosylmethionine (Ado Met) in brain and liver of fruit bats (Rousettus aegyptiacus) was examined.2. Test animals exposed to N2O–oxygen (50:50, v/v) developed ataxia and paralysis leading to death after an average of 9·8 weeks (n 6). Animals receiving pteroylmonoglutamic acid supplements in the diet became ataxic earlier (mean 8·8 weeks) while those receiving methionine supplements survived for significantly longer periods (12·5 weeks, P < 0·01).3. Plasma cobalamin levels indicated severe depletion of cobalamin stores in N2O-exposed animals.4. The mean concentration of Ado Met in the brain of N2O-treated bats was nearly 50% higher than that of untreated controls. Ado Met levels in treated bats receiving pteroylmonoglutamic acid or methionine supplements were respectively 18 and 25% higher than in controls. In contrast, the concentration of Ado Met in the liver of all the N2O-treated groups was slightly lower than in controls.5. These results suggest that the N2O-induced neuropathy in the fruit bat is not related to a depletion of Ado Met in the nervous system.

AbstractA new genus and species of filarioid worm is described from the peritoneal cavity of fruit bats, Pteropus hawaiiensis from Fiji and the name Chiropterofilaria brevicaudata n. sp. is given to it. The microfilaria is described. This appears to be the first record of a nematode from this host. The new genus is differentiated from its nearest genus Lemdana in that the spicules are only slightly unequal; and in the female worms, the oesophagus usually make several turns around the vagina before joining the intestine. From the same host, a second microfilaria, Microfilaria fijiensis n. sp. is described, the adults of which were not found.

AbstractAlong with its many advantages, social roosting imposes a major risk of pathogen transmission. How social animals, and especially free-ranging mammals, reduce this risk is poorly documented. We used lipopolysaccharide injection to imitate bacterial sickness in both a captive and a free-ranging colony of an extremely social, long lived mammal – the Egyptian fruit bat. We monitored behavioral and physiological responses using an arsenal of methods, including on-board GPS and acceleration, video, temperature and weight measurements, and blood samples. Sick-like bats exhibited an increased immune response, as well as classical illness symptoms including fever, weight loss, anorexia, and lethargy. Notably, they also isolated themselves from the group by leaving the social cluster and avoiding contact. Free-ranging individuals ceased foraging outdoors for at least two nights. Together, these sickness behaviors demonstrate a strong, integrative immune response which promotes recovery of infected individuals while protecting their group members from transmission of pathogens, and at the same time, reducing spillover events outside the roost.

Timorese fruit bat(Pteropusvampyrus)is the only fly mammalian with its unique behavior which hanging upside down inspite of its pregnancy. This research is aimed to reveal the morphology of the Timorese fruit bats and the distribution of neutral carbohydrate within this organ. Three uterus samples derived from three different Timorese fruit bats were used in the research.Both macroscopical and microscopical examinations using H&E and PAS methods were applied. Macroscopically, Timorese fruit bats showedsoft reddish white duplex uterus. Meanwhile microscopically, endometrium consisted of epithelial layer and lamina propria and was the place where simple tubular glands located. The epithelial layer comprised of simple cylindric secretory cells and ciliated cells. Neutral carbohydrate distribution was seen within this epithelial layer. Myometrium was a thick circular smooth muscle layer which consisted of smooth muscle separated by collagen and elastic fibre. Perimetrium was a visceral layer and consisted of mesothelial cells.
