2012 review

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.

By: W. Hoffmann n, E. Geiger n, S. Gotsch n, D. Rossatto *, L. Silva *, O. Lau n, M. Haridasan*, A. Franco *

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.

2010 journal article

Allocation to leaf area and sapwood area affects water relations of co-occurring savanna and forest trees

OECOLOGIA, 163(2), 291–301.

By: S. Gotsch n, E. Geiger n, A. Franco *, G. Goldstein*, F. Meinzer * & W. Hoffmann n

author keywords: Leaf area index; Huber value; Sap flow; Brazil; Cerrado
MeSH headings : Biomass; Brazil; Droughts; Ecosystem; Geography; Plant Leaves / physiology; Plant Roots / physiology; Plant Stomata / physiology; Seasons; Species Specificity; Trees / classification; Trees / physiology; Water / analysis; Water / metabolism
TL;DR: Despite significant differences in water relations, relationships between traits such as wood density and minimum ΨL were indistinguishable for the two species groups, indicating that forest and savanna share a common axis of water-use strategies involving multiple traits.

2009 journal article

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

ECOLOGY, 90(5), 1326–1337.

By: W. Hoffmann n, R. Adasme n, M. Haridasan*, M. Carvalho*, E. Geiger n, M. Pereira*, S. Gotsch  n, A. Franco *

author keywords: alternate stable states; Cerrado, Brazil; evergreen forest; fire ecology; gallery forest; hysteresis; positive feedback; riparian forest; savanna; topkill
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.
