Tropical volcanoes are an important but understudied ecosystem, and the relationships between plant species diversity and compositional change and elevation may differ from mountains created by uplift, because of their younger and more homogeneous soils. We sampled vegetation over an altitudinal gradient on Mt. Rinjani, Lombok, Indonesia. We modeled alpha- (plot) and beta- (among plot) diversity (Fisher's alpha), compositional change, and biomass against elevation and selected covariates. We also examined community phylogenetic structure across the elevational gradient. We recorded 902 trees and shrubs among 92 species, and 67 species of ground-cover…??

The study assessed the Philippine-endemic and Mindanao-endemic bird communities of two mountains in Agusan del Norte – Canticol, Tubay and Mt. Hilong-hilong, Remedios T. Romualdes (RTR) from September to November, 2008 using eight-minute fixed-radius point counts. Habitat variables included vegetation structure, elevation, slope and incidence of anthropogenic disturbance. Non-linear regression analysis and AICc model selection were used to determine the habitat variables that influence the richness and abundance of endemics in the two sites. Canticol had lower mean density of large and medium trees and higher degree of anthropogenic disturbance than Mt. Hilong-hilong. There were 31 Philippineendemic birds (four threatened)…
