Basaltic Soils

A preliminary account is given of lowland tropical rain forest in which Agathis obtusa is dominant on basaltic soils. On the islands of Erromanga and Aneityum the shade tolerant Agathis seedlings often develop in close proximity to the parent trees, usually in small canopy gaps provided by the death or deterioration of Calophyllum and other associated broadleaved trees. There is no accumulation of litter or mor humus beneath Agathis obtusa and no evidence of podzolization was found. Agathis obtusa appears to be one of the most stable components of the lowland primary forest in the New Hebrides and no windthrown trees were found. It is suggested that the emergent Agathis could moderate the effect of hurricane-force winds on the broadleaved canopy but that the smaller canopy breaks allow the growth of previously established but stagnating Agathis seedlings; similar release of Agathis regeneration has resulted from small-scale selective logging on Aneityum.

We observed a period of famine in the lowland tropical rain forest of Sabah, Malaysia from August 1999 to September 2000. All six Malayan sun bears (Helarctos malayanus) that were captured and radio-collared were in poor physical condition, and two were later found dead. The physical condition of bearded pigs (Sus barbatus) that were captured, observed or photographed by camera traps also revealed that the pigs were in various stages of emaciation and starvation. We surmise that the famine resulted from prolonged scarcity of fruit during an intermast interval in the study area. These phenomena of emaciated animals and fruit scarcity have also been reported from other areas of Borneo. Lowland tropical rain-forest trees of Borneo display supra-annual synchronized general fruiting. We believe that the starvation we observed and the generally low density of large animals in Borneo forests is a consequence of a history of prolonged food scarcity during non-general-fruiting years, but may be accentuated by anthropogenic factors such as forest fragmentation, selective logging, and reduced density of fig trees in logged forests.

Microhabitat use and habitat-abundance relationships of four freshwater shrimps, Atyopsis moluccensis, Macrobrachium pilimanus, Macrobrachium trompii and Macrobrachium neglectum, were surveyed in tropical streams running through primary and secondary forests in Borneo, East Malaysia. Underwater observations revealed that A. moluccensis preferred relatively high water velocity and a boulder substrate. Macrobrachium pilimanus also preferred high water velocity and a cobble substrate, whereas M. trompii occupied stream margins with slow current and fine substrates (from POM (particulate organic matter) to pebbles). In contrast, M. neglectum was distributed relatively evenly through the stream channel. The abundance of A. moluccensis, M. pilimanus and M. trompii in the stream reaches was best explained by the abundance of boulders, cobbles and POM, respectively, suggesting that the amount of preferred microhabitat is an important factor affecting shrimp abundances in the tropical rain-forest streams. The primary-forest reaches were dominated by coarse substrates, such as cobbles and boulders, while a great proportion of the streambeds in the secondary-forest reaches were covered with sand. Owing probably to such habitat differences, the abundance of both A. moluccensis and M. pilimanus, which preferred coarse substrates, was less in the secondary- than in the primary-forest reaches. These suggested that loss of preferred habitat, namely decreased coarse substrate availability, by sedimentation resulting from riparian deforestation had altered the shrimp assemblage structures.

Based on the results of research on the vegetation around Padang Lawas Temples, Padang Lawas Regency, North Sumatera Province, can be known that Padang Lawas Temple sites are located in vegetation environment of lowland tropical rain forest with a high level diversity of plant families, one of those plant families is Euphorbiaceae with one of its species, Phylanthus emlica. L(Balaka). Phylanthus emlica is a type wild plant that grows open spaces in lowland tropical rain forests. Observing its life characteristic and its habitat, then Balaka plant (Phylanthus emlica) in Padang Lawas Temples’ yards was not planted in purpose planted but grows naturally. Balaka plant (Phylanthus emlica) has different name in every area. In Melayu, this plant is known as malaka. In Minangkabau known as balaka, in Sunda known as malaka and in Java, this plant is known as Kemloko, meanwhile in Madura and Bali this plant is called mlakah ,and karsinta in Flores (NTT)

Banyak Angkrem and Kedung Kopong are medium lowland tropical rain forest areas where many types of orchids can be found. This study aims to determine the types and diversity of orchids found in the area of ​​Banyak Angkrem and Kedung Kopong. Data was collected using the Visual Encounter Survey (VES) method with a radius to the right and to the left  5 m from the observation path with a research area ​​6.24 ha. The results showed that in the two areas found 15 species of orchids consisting of 10 species of epiphytic orchids (Acriopsis lilifolia, Agrostophyllum laxum, Bulbophyllum sp 1, Bulbophyllum sp 2, Dendrobium sagittatum, Dendrobium sp, Oberonia lotsyana, Pholidota sp, Polystaschya concreta, Vanila. planifolia) and 5 species of terrestrial orchids (Geodorum densivelorum, Malaxis ophrydis, Malaxis sp, Nervilia plicata, Perystilus goodyroides). The level of diversity (H ') of orchids in the two regions is classified as moderate with an H' value of 2.22
