  • Fig. 1 Historical changes in EVI over 30 years of fire suppression.

    Historical changes in the EVI over 30 years of fire suppression, as determined by Landsat images. Each study plot is denoted by a different symbol and a separate regression line.

  • Fig. 2 Carbon stocks and species richness due to forest encroachment.

    Changes in (A) carbon stocks, (B) plant species richness, and (C) ant species richness over gradients of forest encroachment. All variables were significantly correlated with basal area (P < 0.0001) except for the number of forest and generalist ants (P = 0.42).

  • Fig. 3 Carbon-biodiversity trade-offs across savanna-forest transitions.

    Carbon-biodiversity trade-offs across savanna-forest transitions. Relationships between ecosystem carbon stocks and species richness of (A) plants and (B) ants. All relationships are statistically significant (P < 0.0001). Fitted relationships: all plants, y = 245.88x−0.271; savanna plants, y = 1953.4x−0.975; all ants, y = 198.68x−0.426; savanna ants, y = 2258.8x−1.380.
