Abstract

Termites play important roles in organic matter decomposition, nutrient cycling, and soil structure in tropical rain forests. When forests are replaced by agriculture, termite species richness, abundance, and function often decline. This research was aimed to determine diversity and composition of termites in three land use types (kemiri gardens, simple and complex agroforestry). Methods of sample collection using transects with a size of about 2 x 100 m, divided into 20 sections (2 x 5 m). The collected samples were collected for identification purposes. Variables measured the diversity of termites which includes the type and number of species (species richness) found in each land use. Diversity and abundance of species of termites were analyzed using the Shannon Diversity IndexWienner. The results showed that the total number of termite species founded in all area was 6 species comprising 2 families, i.e. termitidae and rhinotermitidae. Alpha diversity of termite founded in kemiri gardens was 4 species, and 5 species founded in complex agroforestry and 3 species founded in simple agroforestry. The highest frequency of termite species was 0,5 that achieved by Odontotermes sp in kemiri gardens and simple agroforestry, while the lowest frequency was 0,05 that achieved by Schedorhinotermes sp. in candlenut gardens. Further, the Shannon species diversity Index (H’) of each land use types were 0,93, 0,95 and 1,47 in simple agroforestry, kemiri gardens and complex agroforestry, respectively.

Abstract

Different elevation of lands can affect environmental conditions such as light intensity, temperature, and humidity. The environmental conditions will affect the growth and species of weeds. The aim of this study was to compare the diversity and species composition of weed comunities on highland and lowland of cacao plantation. The study was conducted by colecting the weed species from 25 plots with a size of 2 x 2 m. Every plot was placed by purposive sampling. The result showed that there were 26 species of weeds on highland while only 15 species of weeds were found on lowland. Weeds on highland was dominated by Ageratum conyzoides with important value index (IVI) of 62.07% while on lowland was dominated by Euphorbia hirta with IVI of 26.56%. The weeds community has a medium diversity index while the value of Similarity Index (IS) was low (4.87%) between weeds community on highland and lowland. It could be concluded that different environmental condition would affect the number and species of weeds.
