REDD is short for Reduced Emissions from Deforestation and Degradation in Developing Countries. After developed countries highly developed their economy, global warming, forest conservation and biodiversity become the main topics they concerned about, and, a blame to poor countries in politics, which reminds me of that famous book our common future, which is full of [...]

Malesia has extremely rich flora. This region containing high concentrations of endemic flora (Sodhi et al, 2004). Furthermore, this region also overlaps with three biodiversity hotspots for conservation. Biodiversity hotspots are areas of high priority for conservation and may be selected on the basis of their local species richness, degree of concentration of rare species [...]
ESSAY ON INFLUENCE OF SPATIAL AND SIZE SCALE ON PHYLOGENETIC RELATEDNESS IN TROPICAL RAINFOREST COMMUNITIES
Go to the original post at peter's blogSaturday, August 1st, 2009
Introduction
Evolutionary relatedness among various groups of organisms helps to explain community interactions in an ecosystem. There are three mechanisms that are often invoked to understand the structure of diversity within ecological communities; neutrality, competitive exclusion and abiotic filtering. In their study, Swenson et al., 2007 studied evidence for phylogenetic conservatism and spatial scale relatedness in tropical [...]

Essay on “Phylogenetic analysis of trophic associations” (Ives & Godfray 2006)
Closely related species may share traits simply because they have inherited them from a common ancestor. This idea underlies the concept of “independent contrast” (Felsenstein 1985), which has been widely used in studying correlated evolution and adaptive significance (Price 1997).
Most previous studies focus on estimating [...]
using phylogenetics in understanding community dynamics
Go to the original post at carla's blogSaturday, August 1st, 2009
This essay stems from the Webb paper on exploring the phylogenetic structure of a tree community in Borneo (2000). I chose the study because I was particularly interested in the idea of using phylogenetic approach in understanding ecological communities; that you can somehow trace ecological processes operating in a community (general; community perspective) by [...]
