Estimation of Canopy Leaf Area Index of Tropical Rainforests of Sri Lanka from the Normalized Difference Vegetation Index along a Wide Altitudinal Gradient

Madhumali, R.M.C.; Wahala, W.M.P.S.B.; Welikanna, D.R.; Dunendran P.; Sanjeewani, H.K.N.; Samarasinghe, D.P; De Costa, W.A.J.M. (Department of Forestry and Environmental Science, University of Sri Jayewardenepura, Sri Lanka, 21-01-22)

The leaf area index (LAI) of a forest is a key determinant of its primary productivity. Estimation of LAI via remote sensing of forest canopies offers an alternative to direct measurement, which is difficult in tropical ...
Inter-Relationships Between Canopy Openness and Vegetation Diversity in Tropical Rainforests of Sri Lanka Across a Wide Altitudinal Gradient

Madhumali, R.M.C.; Wahala, W.M.P.S.B.; Sanjeewani, H.K.N.; Samarasinghe, D.P.; De Costa, W.A.J.M. (Sabaragamuwa University of Sri Lanka, 16-12-20)

As light transmission is essential for plants in the forest under story, canopy openness (CO) could be closely related to vegetation diversity in tropical rainforests. This study investigated the variation of CO of wet ...
Response of Canopy Leaf Area Index and Architecture of Tropical Rainforests in Sri Lanka to Climatic Variation along an Altitudinal Gradient

Madhumali, R.M.C.; Wahala, W.M.P.S.B.; Sanjeewani, H.K.N.; Samarasinghe, D.P.; De Costa, W.A.J.M. (Postgraduate Institute of Agriculture (PGIA), 01-01-21)

The foliage canopy of a forest is important for radiation capture, carbon sequestration and regulation of water relations. The objective of this work was to quantify the response of key canopy properties of tropical ...
Response of tree community composition, plant diversity and aboveground tree biomass in tropical rainforests of Sri Lanka to variation in altitude

Sanjeewani, H.K.N.; Samarasinghe, D.P.; Jayasinghe, H.D.; Gardiyawasam, P.H.; Wahala, W.M.P.S.B.; Wijetunga, W.M.G.A.S.T.B.; Ukuwela, K.D.B.; Gomes, P.; De Costa, W.A.J.M. (Postgraduate Institute of Agriculture (PGIA), 01-01-20)

Tropical rain forests (TRFs) are a major carbon sink and play an important role in regulating the global climate. Floristic composition, structure and carbon storage in biomass of TRFs could vary substantially with climatic ...
