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)


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.

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

Strumigenys fairchildi Brown, 1961 is recorded for the first time in Brazil. This ant species was previously known only from a few specimens collected in Costa Rica, Panama and Ecuador. The worker S. fairchildi was collected at the Parque Estadual do Cristalino, a continuous area of Amazon tropical rain forest protected for biodiversity conservation in the municipality of Novo Mundo, Mato Grosso state. In addition, we present a distribution map and high-resolution images of the worker.
