“…Thus, plant community in the protected site may be limited by loss of soil nutrients, whereas in the annually burned site soil nutrients adsorbed in clay may be gradually released to soil. Water holding and nutrient availability are determinants for vegetation diversity and structure (Dubbin et al 2006). Whereas some studies, as well as ours, found that clay proportion increased with fire frequency in savannas (e.g., Spera et al (Hubbert et al 2006) or was kept constant (Bowker et al 2004).…”

Fire is an important ecological factor that structures savannas, such as the cerrado, by selecting plant species and altering soil nutrient content. In Emas National Park, central Brazil, we compared soils under three different fire regimes and their relationship to the cerrado species they support. We collected 25 soil and vegetation samples at each site. We found differences in soil characteristics (p<0.05), with fertility and fire frequency positively related: in the annually burned site we found higher values of organic matter, nitrogen, and clay, whereas in the protected site we detected lower values of pH and higher values of aluminum. We also observed differences in plant community structure, with distinct floristic compositions in each site. Floristic composition was more related to sand proportion (intra-set correlation=0.834). Different fire frequencies increase environmental heterogeneity and beta diversity in the Brazilian cerrado.

“…Physicochemical characteristics included pH, moisture content, specific gravity, hydraulic conductivity, particle size analysis (Gee and Bauder, 1986), hydraulic conductivity, organic carbon (Walkley and Black, 1934), CEC (Chapman, 1965), AEC (Mehlich, 1948). Exchangeable cations in the media such as Ca 2+ , Mg 2+ , K + , Na + , Al 3+ , Si 4+ , Fe 3+ were measured as per method given by Dubbin et al (2006). ECEC was calculated as the sum of exchangeable cations.…”

“…However, responses to aluminum toxicity vary among plant species, and some are adapted to high levels of aluminum, being restricted to this soil condition (Haridasan 2000). Therefore, species composition is related to soil texture, aluminum saturation, nitrogen, and organic matter concentration (Higgins et al 1997;Dubbin et al 2006;Silva & Batalha 2008). …”

Influence of fire history and soil properties on plant species richness and functional diversity in a neotropical savanna

Differences in plant species richness and composition are associated with soil properties and disturbances such as fire, which can therefore be key determinants of species occurrence in savanna plant communities. We measured species richness, using nine plant functional traits and abundance to calculate three functional diversity indices. We then used model selection analyses to select the best model for predicting functional diversity and richness based on soil variables at sites with three different fire frequencies. We also calculated the community-weighted mean of each trait and used ordination to examine how traits changed across fire frequencies. We found higher species richness and functional dispersion at sites that were more fertile and where fire was frequent, and the opposite at such sites where fire was infrequent. However, soil properties influenced functional evenness and divergence only where fire was infrequent, with higher values where soils were poorer. Fire can change functional traits directly by hindering development of plants and indirectly by altering competition. Different fire frequencies lead to different plant-soil relationships, which can affect the functioning of tropical savanna communities. Functional diversity components and functional identity of the communities are both affected by fire frequency and soil conditions.
