ABSTRACTBat communities in the understorey of primary lowland dipterocarp forest in peninsular Malaysia and Sabah were sampled with mist nets and harp traps to estimate their trophic structure. Overall, 4 of 26 species (15%) at one site, and 6 of 33 species (18%) at the other site were frugivores, while the remainder were insectivores. In terms of individuals, 7–12% of all captures were frugivores. However, the true proportion of frugivores at both sites was probably closer to 1%, because the sampling procedures were strongly biased towards frugivores. In contrast, previously published studies indicate that frugivores comprise 34–48% of species, and up to 80% of individuals in bat communities in the understorey of Neotropical forest. These results support the hypothesis, developed from studies of bird communities, that the under-storey of Malaysian dipterocarp forest supports relatively few obligate frugivores, at least in non-masting years. However, further data are required on bats in the canopy, and on the foraging ranges of bats to compare the absolute densities of bats in Malaysian and Neotropical forests.

A study on amphibian fauna at the lowland dipterocarp forest of Lubuk Semilang Recreational Park, Langkawi, Kedah, Peninsular Malaysia was conducted between December 2018 and June 2019. We recorded 18 species of amphibians from 14 genera and 6 families. These include seven new records for Lubuk Semilang, which are Fejervarya limnocharis, Limnonectes hascheanus, Megophrys aceras, Kaloula pulchra, Microhyla butleri, Pulchrana laterimaculata, and Polypedates discantus. We also recorded a new anuran record for Langkawi Archipelago, Pulchrana laterimaculata, and two endemic species of Malaysia, Leptobrachium smithi and Limnonectes macrognathus. Results from this survey indicate the amphibian species of the Langkawi Archipelago has increased from 28 to 29 species. Data published through GBIF (Doi: 10.15470/f0diow)

ABSTRACTChanges in the lowland dipterocarp forest structure and composition are described for a 34-year period between 1947 and 1981 in Sungei Menyala Forest Reserve, Peninsular Malaysia. Although tree density declined by about 10%, basal area changed little, averaging 32.4 m2 ha−1. Size class distributions in 1947 and 1981 were not significantly different. Mortality rates were independent of size class. Mortality exceeded recruitment during the first 16 years to 1963, but was thereafter almost exactly balanced by recruitment. Recruitment rate increased significantly for the latter part of the study.Mortality was greater than average for understorey species and lower for emergents. Pioneer and late seral species together showed significantly higher mortality rates. Amongst the commoner species, emergent, late-seral and pioneer species showed the highest annual diameter growth rates with species averages over all size classes exceeding 3 mm yr−1; rates for main-canopy species were between 1.5 and 2.5 mm yr−1, and understorey species generally less than 2 mm yr−1.Species richness was almost identical in 1947 and 1981 (243, 244 species), but a clear decline (to 229 species) between 1953 and 1971 was recovered by 1981. Most species showed little net change in density over the 34-year period, but eight of the 32 commoner species showed significant changes, all unidirectional. These changes in species composition are not negligible, but further analysis is needed to determine if, for example, they are related to disturbance of part of the plot in 1917.

Batu Hampar Recreational Forest (BHRF) is a lowland dipterocarp forest located in the northwestern region of Peninsular Malaysia and has not been surveyed for its herpetofauna until now. A preliminary survey of the herpetofaunal diversity of BHRF was conducted from September 2018 to February 2019 resulting in 103 individuals (37 species) of amphibians and reptiles found. This includes 14 species of frogs from six families and 10 genera; 14 species of lizards from four families and 11 genera; eight species of snakes from five families and eight genera; and one species of freshwater turtle. From these results, Batu Hampar Recreational Forest has a high herpetofaunal diversity with a Simpson’s Index of Diversity of 0.869 and a Shannon-Wiener Diversity Index of 2.930. In the future, additional surveys over longer periods of time should be conducted at BHRF to produce a more complete checklist.

The importance of disturbances for the dynamics of tropical forests has been described by Whitmore & Burslem (1998). Among the phenomena which they classify as large scale disturbances are those caused by wind. The most extensive of these occur within the hurricane (cyclone) belt (10-20° from the equator) but outside this belt large blowdowns of trees are known to occur, perhaps most spectacularly in the Brazilian Amazon (Nelson et al. 1994). There is evidence that rare wind storms influence the dipterocarp rain forests of Peninsular Malaysia, 2-6°N. One famous storm in November 1880 which devastated hundreds of square kilometres of forests in Kelantan, north-east Malaya, was probably an aberrant cyclone (Wyatt-Smith 1954). Smaller windstorms which have blown down several hectares of forests have been reported from Malaysia including Borneo (Ashton 1993) but their frequency and extent have not been well documented (Whitmore & Burslem 1998). At Barito Ulu, Central Kalimantan, one such storm occurred recently and the fortuitous combination of a well patrolled trail system and the localization of the storm has allowed a detailed assessment of the forest damage.
