Nitrogen (N) enrichment of tropical ecosystems is likely to increase with rapid industrial and agricultural development, but the ecological consequences of N additions in these systems are not well understood. We measured soil Noxide emissions and N transformations in primary rain forest ecosystems at four elevations and across two substrate types on Mt. Kinabalu, Borneo, before and after short...

1. Arid ecosystems are a patch mosaic of plants and biological soil crusts that have been described as islands and mantles of fertility, respectively. To determine whether these patches are metabolically linked by a fungal network of dark septate and arbuscular mycorrhizal fungi (AMF), we measured translocation of nitrogen (N) and carbon (C) in a desert grassland using 15 N-NO 3 and 13 C 5 , 15...

Calocybe indica, a tropical edible mushroom, is popular because it has good nutritive value and it can be cultivated commercially. The current investigation was undertaken to determine a suitable substrate and the appropriate thickness of casing materials for the cultivation of C. indica. Optimum mycelial growth was observed in coconut coir substrate. Primordia initiation with the different sub...

The decomposition of organic matter is a major biogeochemical process because of its effect on ecosystem productivity and its implications on climate change. Temperature and moisture are two variables that have a tremendous influence on microbial decomposition. Decomposition is also influenced by substrate type, in which higher quality substrates often have greater decomposition than lower qual...

In developing countries, or in those countries that do not produce peat, forest soil has traditionally been used as a substrate for cultivation of seedlings nurseries. However, found to high quality. Additionally, the harvesting within forested stands negative environmental connotations. The objective this study was evaluate use Acacia cyanophylla–based compost an alternative growing media prod...
