Relation between environmental factors and structure of Atlantic Forest fragments

Forest fragmentation affects the structure and interactions of plant communities on several levels is considered one causes extinction species. This study aimed to verify if size, isolation, altitude soil attributes influence species richness, basal area, abundance composition in Atlantic fragments. We sampled shrubby-arboreal individuals ten fragments, measured isolation. To effects environment abundance, richness we utilized generalized linear mixed models; detect patterns distribution concerning altitude, constructed ordination histograms; determine associations between composition, performed a canonical correspondence analysis. A group was related soils with higher Base Saturation, Organic Matter, Phosphorus, Silt pH; another had more relationship variables such as Aluminium, Iron, Clay Altitude, third Sulfur, Zinc Boron. Some occurred only smaller less elevated others were exclusive larger The size isolation fragments did not explain richness. interaction texture nutrients changes community. Species area density fertile soils. increases fragment
