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.

Ebook "Recarbonization of the biosphere: Ecosystems and the global carbon cycle" increasing amounts of carbon dioxide (CO2) are added to the atmosphere by fossil fuel combustion but the biosphere is a potential C sink. Thus, a comprehensive understanding of C cycling in the biosphere is crucial for identifying and managing biospheric C sinks. Ecosystems with large C stocks which must be protected and sustainably managed are wetlands, peatlands, tropical rainforests, tropical savannas, grasslands, degraded/desertified lands, agricultural lands, and urban lands.

Ebook "The future of the world’s forests: Ideas vs Ideologies" seeks answers to this question. It examines the often dysfunctional relationships between various members of the international forest constituency, which have so often prevented the formation of consensus. It also explores the tendency to pursue technical and politically convenient ‘fixes’ focused on the internal workings of the forest sector, while ignoring the overwhelming influence of external forces on the fate of forests.

The present study, based on the molecular data of seven DNA regions supported the relationship within the genus Altingia. Three clades were recognized in this genus. The species A. excelsa from Lao Cai province of Vietnam was well supported as closely related to A. siamensis by molecular data, this result is congruent with morphology, and distribution.

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.

Ha Long bay - Cat Ba island located in the Northeast of Vietnam, in the area of Ha Long city (Quang Ninh province) and Cat Hai island district (Hai Phong city) is the largest limestone island in Vietnam. Features of biodiversity include the seven typical ecosystems of tropical limestone islands, namely tropical rainforest ecosystem, cave ecosystem, mangrove ecosystem, tidal ecosystem, coral reef ecosystem, soft-bottom ecosystem. Ha Long - Cat Ba also represents a high level of species diversity with 4,622 species of plants and animals on land and in the sea.

The study of habitat distribution of fruit-feeding butterflies in the tropical rainforest is important for understanding their diversity in the tropics and for determining responses of butterflies to forest disturbance. Some previously works demonstrate the construction and methods of using the portable bait traps for collecting and taxonomical and ecological studies of tropical butterflies (De Vries, 1988; Austin, Riley, 1995; Tangah et al., 2004; Hamer et al., 2006; Hayes et al., 2009). The current work is the first to describe the bait trap use in Vietnam.

In this research, the dead trees were defined as the standing trees that died between the two occasions at which measurements were taken. The data on 300 subplots from 12 permanent sample plots were collected. The response variable was the number of dead trees per subplot.

Cumulatively, all our individual footprints make up the unsustainable total demand. The solution to this problem is for people to take individual action to break down that large footprint. We need to change the way we live to combat climate change, conserve the world’s forests and protect our oceans. No-one wakes up in the morning and consciously decides to contribute to global warming; to help cut down a tropical rainforest; or to deprive future generations of a decent standard of living.

The city-state of Singapore is a wonderful place where many of Asia’s cultures, new and old, as well as tropical beaches and pristine rainforest, can all be experienced within a very small area. The official language is English, but Singapore’s many ethnic groups, such as Malay, Indian, Arab and the Chinese put their own unique mark on the city, each with their own city quarters, shops, restaurants and festivals.
