Disturbance and Tropical Pioneer Species: Patterns of Association Across Life History Stages

BAckground

The authors studied pioneer species common in the Sinharaja World Heritage Reserve in Sri Lanka to characterize differences in relation to canopy openness and type, and intensity of disturbance using a combination of field work, canopy photos, and regression models.

Ecological Significance of Crown Functional Traits Across Size Classes and Disturbance Environments in Eight Pioneer Species in a Sri Lankan Rain Forest

background

This article evaluates the tree crown characteristics of eight pioneer tree species in the Shorea-Mesua vegetation type (an aseasonal, mixed dipterocarp forest) around the Sinharaja World Heritage Forest Reserve in southwest Sri Lanka.

Research Goals & Methods

The crown surface area, crown volume, and live crown ratio were measured as well as evaluated for their correlation with tree size classes and disturbance causes.

The Ecophysiology of Pioneer Tree Species in Relation to their Disturbance Ecology in a Wet Lowland Rainforest, Sri Lanka

Background

This dissertation evaluates pioneers species and their response to light availability and disturbance characteristics in the Shorea-Mesua vegetation type (an aseasonal, mixed dipterocarp forest) around the Sinharaja World Heritage Forest Reserve in southwest Sri Lanka.

Effects of fire on the recruitment of rain forest vegetation beneath Pinus caribaea plantations, Sri Lanka

Background

Groundstory fires burn forest understories and can impact advance regeneration, contributing to conversion of forests to fire-sustained grasslands or fernlands. While plantations of fire-tolerant trees have been successfully established on these sites, managing fire in the newly developing understory remains an issue of concern.
