Abstract

POWLING, A., PHILLIPS, A., PRITCHETT, R., SEGAR, S. T., WHEELER, R. & MARDIASTUTI, A. 2015. The vegetation of Lambusango Forest, Buton, Indonesia. Reinwardtia 14(2): 265 - 286. - Lambusango Forest is a tropical rainforest on the island of Buton, which lies close to south east Sulawesi. The forest covers an area of about 95.000 ha, with different parts of the forest having different levels of conservation protection. It lies on rocks of both calcareous (limestone) and non-calcareous (sandstone, conglomerate, peridotite and chert) nature, which give rise to soils with varying pH values, nutrient levels and water-holding capacities. The climate is seasonal, with a dry season of three months and considerable year-to-year variability due to El Nino and La Nina events. The vegetation on the different soils and in different habitats has been studied. Over 300 species of vascular plants found in the forest and surrounding areas are listed, including trees and shrubs, herbs, climbers, epiphytes, ferns and club-mosses. Two genera, Calamus with 18 species and Ficus with 29 species, are particularly species-rich, apparently due to their ability to occupy numerous edaphic and ecological niches. Species of these two genera are also good colonists and so better able to reach Buton in the recent past than other species. The plants of the forest indicate that Buton is floristically very similar to Sulawesi, with at least 83% of the species found in the forest also being known from Sulawesi. Most of the plant families and genera present on Buton are common in SE Asia, indicating colonisation primarily from that continent. Many fewer families and genera have colonised from the Australasian continent. The conservation of plant diversity is necessary for the forest to continue as a functioning ecosystem, to the benefit of the animals of the forest and also the local people.

PRITCHETT, R., PHILLIPS, A., MARDIASTUTI, A. & POWLING, A. 2016. Rattan diversity and broad edaphic niches in a tropical rainforest of Buton, Sulawesi, Indonesia. Reinwardtia 15(2): 99 – 110. — This paper attempts to answer the question: how can at least 20 species of rattan palms in the genus Calamus (family Palmae (Arecaceae)) co -exist in a rainforest? A survey of rattans was made in Lambusango Forest on Buton, an island close to south east Sulawesi, in Indonesia. Rattan species and numbers were recorded in 87 quadrats of 30 × 10 m, laid out along linear transects in habitats with a variety of soils. Evidence for edaphic (soil) niches was sought. Different rattan species were found to be adapted to soils with different conductivity and pH values. Standardised mean difference (d) scores were calculated for pairs of species based on their response to soil pH. Of the 66 pairs tested, 61 were found to be significantly different statistically. Such differences suggest, but do not prove, that many species occupy different edaphic niches. It was found that species which show a preference for soils with intermediate pH values (5.0 to 6.5) can grow in soils with a wide range of pH values, implying broad edaphic niches and that competition between these species is weak. Correspondence analysis shows that many species do not distinguish greatly between many soils with intermediate pH values. It is concluded that rattan species show evidence for having different edaphic niches, although the niches for many species are broad. It is speculated that many rattan species may be ecologically equivalent and that a weak version of ecological neutrality theory may apply.
