Structure diversity in three forest types of north-eastern Thailand (Sakaerat Reserve, Pak Tong Chai)

The aim of the present study is to provide a basic knowledge in view of a better understanding of the global structure of threetropical forests at the Sakaerat Environmental Research Station (Pak Tong Chai district, Northeastern Thailand): a drydipterocarp forest (DDF), a dry evergreen forest (DEF) and an intermediate stage (DDFwf), characterized by the absence offire since 29 years in a pyro-climax. These forest ecosystems were contrasted by the composition and floristic structure, thebasal area and the tree density. The species richness increases with the passage from the DDF, the most open environment, to the DDFwf, the most densely wooded. By these tree density and basal area, the DDF (602 trees/ha at DBH ³ 5 cm, 14.2 m2/ha) and the DEF (992 trees/ha at DBH ³ 5 cm, 29.0 m2/ha) studied belong to the typical tropical ecosytems of southeast Asia. The man-made fires and anarchic forest exploitations are a danger for the stability of these different ecosystems

Bioactive compounds of plum mango (Bouea macrophylla Griffith)

The fruit of Bouea macrophylla referred as Plum mango or Gandaria is a popular seasonal fruit, which is widely consumed in the Malay subcontinent. There is ample of traditional knowledge available among the locals on the use of leaves, bark, fruits and seeds of this plant. However, very limited research information and scientific report is available on their composition, phytochemicals or on the bioactive compounds. In the present chapter, we have aimed towards comprehensively providing information on nutritional value, functional qualities, health promoting bioactive compounds and volatile constituents of this underutilized fruit

Land Cover in a Managed Forest Ecosystem: Mexican Shade Coffee

Managed forest ecosystems like shade coffee supply valuable ecological services. Yet little is known about the drivers and characteristics of clearing in such systems. We present a spatial econometric analysis of land cover in a shade coffee region in southern Mexico. We find that plots close to large cities are less likely to be cleared all other things being equal—the opposite of the pattern usually observed in natural forests. In addition, we find that membership in coffee-marketing cooperatives, farm size, and certain soil types are associated with tree cover, while proximity to small town centers is associated with clearing.
