Spatial patterns of forest trees have been long recognized as evidences of underlying biological processes within forests. We used point pattern analysis methods and process-based models to detect the demography and dynamics of trees in a primary rainforest stand. A fully mapped 1-ha plot was investigated in the tropical rain forest of Cuc Phuong National Park. Trees were stem-mapped, diameter-measured at breast height and classified into species.

Structural and spatial patterns of tree species in forests are important indicators to explain which underlying mechanisms or processes regulating forest structure. In this article, techniques of spatial point pattern analysis were used to characterize structural and spatial patterns of two secondary rain forest stands in Cuc phuong National park, Vietnam.

Song Hinh Protected Forest is situated in the Song Hinh District of Phu Yen Province in the South-Central Coastal region of Vietnam. The major forested districts in Phu Yen Province are Dong Xuan, Son Hoa, and Song Hinh. The main forest types include tropical humidity rain evergreen broad leaf closed forest and tropical moist semi-evergreen broad leaf closed forests of natural forests.

DNA barcoding has been widely used to assess species diversity in a variety of ecosystems, including temperate, subtropical, and tropical rain forests. However, due to the difficulties associated with field exploration, most of the species in Truong Sa archipelago have never been barcoded.

Mesua ferrea L. was evaluated for its germination, seedling growth and biomass across four seed size classes. The production of two- and three-seeded fruits was high. The viability of the seeds was 58-81%. Germination was positively correlated with seed weight. Heavier seeds showed early and rapid germination.

Dipterocarpus dyeri (Dipterocarpaceae) is widely distributed in lowland rainforests in southeastern Vietnam. Due to over-exploitation and habitat destruction in the 1980s and 1990s, this species is listed as threatened. Understanding the genetic variation and mating rate among D. dyeri population that occurs in forest patches is necessary to establish effectively conservation strategies for this species. To conserve the species in tropical forests, genetic diversity and mating rate were investigated using eight microsatellites (single sequence repeat, SSR) as markers.

Explaining the high diversity of tropical rain forest has been a challenge for ecologists for decades. We applied a recent technique of spatial statistics that is Individual species area relationship (ISAR) to study diversity structure of a tropical broadleaved forest based on individual species. The ISAR is combined by species area relationship and Ripley’s K to measure the expected diversity of individual specific species in circular neighborhoods with variable radius of moving window circles around an arbitrary individual of a focal species.

Hevea brasiliensis, a forest tree, which is indigenous to the tropical rain forests of Central and South America and the only major commercial source of natural rubber (NR), is one of the most recently domesticated crop species in the world. The modern age of NR in India actually started during the 1870s when the British successfully transported Hevea seeds from Brazil for planting in the then British India1.'. Rubber seems to be a fairly straightforward word.

The planet is a marvelous place with its blue skies, wild storms, deep lakes, and rich and diverse ecosystems. The tides ebb and flow, baby animals are born in the spring, and tropical rain forests harbor an astonishing array of life. The Earth sustains living things and provides humans with the resources they need to maintain a bountiful way of life. These resources include water, soil, and nutrients to grow food, and the mineral and energy resources to build and fuel modern society, among many other things....

As resources become scarce, they become more valuable. Value is evidenced both by the increasing prices of resources and by controversy over resource allocation and management. From forest harvesting and land use conversion throughout North America, to the fragmentation of tropical bird habitat, to acid rain deposition in Eastern Europe, to Siberian tiger habitat loss in Russia, people have significantly affected the ecosystems of the world. Expanding population pressures continue to cause the price of resources to increase and to intensify conflicts over resource allocation....

The soils of the South American llanos and cerrado grasslands are predominantly old soils from which most of the plant nutrients have been lost. In many places there are layers of laterite (see the sidebar), which give them a red or yellow color. African savanna soils are much younger and more fertile. These shade into arid soils in the north and into wetter soils on high ground. On the southern side there are poor, exhausted, lateritic soils typical of tropical rain forest.
