Soil environment and tree species diversity in tropical rain forest, West Sumatra, Indonesia

Nutritional characteristics of mineral elements in tree species of tropical rain forest, West Sumatra, Indonesia

“…There have been several reports on the relationships between the environmental heterogeneity and the coexistence of species (MacArthur 1958(MacArthur , 1964(MacArthur , 1965Gladfelter and Gladfelter 1978;Pringle 1990). In our study site, a 1 ha permanent observation plot, Pinang Pinang (Hotta 1984(Hotta , 1986(Hotta , 1989, we observed that the heterogeneity of available mineral nutrients in soils tended to be associated with the diversity of tree species (Kubota et al 1995).…”

“…Soils are relatively young Typic Dystropepts, developed from andesite and limestone. Detailed soil characterization was performed by Wakatsuki et al (1986) and Kubota et al (1995).…”

Nutritional characteristics of mineral elements in leaves of tree species in tropical rain forest, west Sumatra, Indonesia

“…Soils were relatively young Typic Dystropepts, derived from andesite and limestone. Detailed soil characterization was performed by Wakatsuki et al (1986) and Kubota et al (1998). Samples. Leaf samples were collected for 608 trees with a dbh above 8 cm in the plot from December 1995 to February 1996.…”

“…All what is required is that plant species show variation in their response to two or more resources or limiting factors (Tilman 1986). We are interested in the mineral nutritional characteristics in both soils and trees which are associated with the maintenance of species richness and their coexistence in tropical rain forests (Masunaga et al 1997Kubota et al 1998). Dynamics of mineral elements in tropical rain forests have been analyzed by several authors (Mo et al 1994;Jordan 1991;Golley 1983), as well as nutritional characteristics of tree species (Chenery 1951;Chenery and Sporne 1976;Gerhard et al 1996).…”

Microbial Community-Level Physiological Profiles Between Tokatli and Sirçali Canyons, Turkey

“…Soil properties are influenced by, for example, soil acidity and nutrient elements of vegetation types (Finzi et al, 1998;van Breemen and Finzi, 1998). Slope differences affect the distribution and development of vegetation and the biological uptake of soil nutrients (Kubota et al, 1998). Soil microorganisms perform in many ecosystem processes, such as nutrient conversion, litter decomposition by regulating the structural and hydrological properties of the soil (Gallardo and Schlesinger, 1994;Kennedy, 1999).…”
