Savanna vegetation-fire-climate relationships differ among continents
Ecologists have long sought to understand the factors controlling the structure of savanna
vegetation. Using data from 2154 sites in savannas across Africa, Australia, and South …

What Limits Trees in C4 Grasslands and Savannas?
Though the distribution of global vegetation can generally be predicted from climate,
grasslands are an exception. C4 grassy biomes cover vast areas that are warm enough and …

The global extent and determinants of savanna and forest as alternative biome states
Theoretically, fire–tree cover feedbacks can maintain savanna and forest as alternative
stable states. However, the global extent of fire-driven discontinuities in tree cover is …

Global resilience of tropical forest and savanna to critical transitions
It has been suggested that tropical forest and savanna could represent alternative stable
states, implying critical transitions at tip** points in response to altered climate or other …

What controls the distribution of tropical forest and savanna?
Ecology Letters (2012) 15: 748–758 Abstract Forest and savanna biomes dominate the
tropics, yet factors controlling their distribution remain poorly understood. Climate is clearly …

Tree cover in sub‐Saharan Africa: rainfall and fire constrain forest and savanna as alternative stable states
Savannas are known as ecosystems with tree cover below climate‐defined equilibrium
values. However, a predictive framework for understanding constraints on tree cover is …

Woody encroachment over 70 years in South African savannahs: overgrazing, global change or extinction aftershock?
Woody encroachment in 'open'biomes like grasslands and savannahs is occurring globally.
Both local and global drivers, including elevated CO2, have been implicated in these …

Woody cover in African savannas: the role of resources, fire and herbivory
Aim To determine the functional relationships between, and the relative importance of,
different driver variables (mean annual precipitation, soil properties, fire and herbivory) in …

A continent-wide assessment of the form and intensity of large mammal herbivory in Africa
Megafaunal extinctions and a lack of suitable remote sensing technology impede our
understanding of both the ecological legacy and current impacts of large mammal …
