Species diversity and abundance of butterfly fauna in four selected habitats in Sinharaja man and biosphere (MAB) reserve
Wednesday, March 26th, 2008Sri Lanka possesses a rich diversity of butterflies compared to other countries in the region, but studies on this interesting taxon remain limited. The present study on butterflies at Sinharaja forest was carried out as an effort of filling this gap to some extent. Data was collected from four different habitat types i.e. primary forest, […]
Edge effects on small mammal assemblages in Sri Lankan rainforests
Wednesday, March 26th, 2008This project was carried out with the objective of investigating edge effects on species richness and abundance of small mammals in rainforests of Sri Lanka. Core and edge habitats of twelve rainforests were live-trapped for five consecutive nights each, during 2006 and 2007. Habitat assessments were also carried out to ascertain differences in microhabitat features […]
Biodiversity of pteridophytes at Mulawella Mountain of the Sinharaja Forest
Wednesday, March 26th, 2008Pteridophyte flora represent an important component of natural vegetation and about 362 taxa belongs to 30 families have been described in Sri Lanka. Even though Pteridophytes play a significant role in natural ecosystems, they are one of the least studied plant categories in Sri Lanka. Although majority of Pteridophytes (81%) have been distributed in the […]

All its members are categorized as highly threatened or threatened in the IUCN red data book. A recent study carried out in order to evaluate the species limits of Stemonoporus, further strengthened its position as the most species-rich endemic dipterocarp genus […]
Wood quality traits in Eucalyptus hybrid in Tamilnadu for pulpwood
Wednesday, March 26th, 2008Eucalyptus tereticornis is utilized mainly for paper pulp as it possess long fibers and fibers with wide overall diameter and thin walls. This paper elicits information on extent of variability, effect of stand age, order of coppice sprouts relative to the original tree and number of coppice sprouts per stool on wood properties of E. […]
Litterfall and Nutrient Accretions to Soil in Teak Plantation
Wednesday, March 26th, 2008In natural forests and manmade protected plantations, nutrient cycling is an important process and it involves various processes within the ecosystem. A considerable amount of nutrients are returned through litterfall in the form of leaves, twigs, bark, flowers, fruits, etc. to the soil and are made available for reabsorption. In order to study the litterfall […]
