Not all trees can make a forest: Tree species composition and competition control forest encroachment in a tropical savanna

Flake, S. W., Honda, E. A., Pilon, N. A. L., Hoffmann, W. A., & Durigan, G. (2022, January 20). JOURNAL OF ECOLOGY.

By: S. Flake n, E. Honda, N. Pilon*, W. Hoffmann n & G. Durigan*

author keywords: Cerrado; competition; forest encroachment; stand development; tree growth; tree mortality; woody encroachment

Ecological thresholds at the savanna-forest boundary: how plant traits, resources and fire govern the distribution of tropical biomes

[Review of ]. ECOLOGY LETTERS, 15(7), 759–768.

author keywords: Alternate stable states; critical thresholds; forest; savanna; tipping point
MeSH headings : Brazil; Ecosystem; Fires; Seedlings; Trees; Tropical Climate
TL;DR: Based on data from central Brazil, it is proposed that these interactions are governed by two critical thresholds; the fire-resistance threshold is reached when individual trees have accumulated sufficient bark to avoid stem death, and theFire-suppression threshold is reach when an ecosystem has sufficient canopy cover to suppress fire by excluding grasses.

author keywords: cerrado; ecosystem dynamics; forest-savanna boundaries; leaf phenology; photosynthesis; specific leaf area
TL;DR: Comparisons of patterns of leaf phenology, stem radial growth and branch growth of co-occurring savanna and forest trees in the Cerrado region of central Brazil suggest that forest trees that invade the savanna tend to present higher growth rates and larger and denser crowns, which enhance shading and could promote changes in equilibrium of forest–savanna boundaries.

Tree topkill, not mortality, governs the dynamics of savanna-forest boundaries under frequent fire in central Brazil

MeSH headings : Brazil; Ecosystem; Fires; Plant Bark; Plant Stems; Population Dynamics; Trees / physiology
TL;DR: The forests studied here appear to be much more resilient to occasional incursion of fire from the savanna, despite being unable to invade frequently burned savannas, and rapid growth will be particularly important for forest species to escape the fire trap, so forests should be restricted to high-resource sites.
