Diversity, stability and landscape dynamics in savanna communities ; Diversidad, estabilidad y dinámica del paisaje en comunidades de sabana

At a border of a savanna plateau (Mesa de Guanipa, Venezuela) we sampled tree communities from different land forms to study relationships between species richness (S), diversity (H’) and compositional stability estimated with two indices: resistance to species turnover (Rst) and resistance to compositional change (Rc). The hypothesis is that in dynamic systems external factors such as substrate dynamics and tendency to disturbance are determinants of community diversity and stability. The five land forms found in the study area represent a temporal sequence starting in the Mesa and ending in... Mehr ...
