Savanna woody encroachment is widespread across three continents.
Tropical savannas are a globally extensive biome prone to rapid vegetation change in response to changing environmental conditions. Via a meta-analysis, we quantified savanna woody vegetation changeExpand

What controls the distribution of tropical forest and savanna?
Forest and savanna biomes dominate the tropics, yet factors controlling their distribution remain poorly understood. Climate is clearly important, but extensive savannas in some high rainfall areasExpand

Firescape ecology: how topography determines the contrasting distribution of fire and rain forest in the south‐west of the Tasmanian Wilderness World Heritage Area
Aim  To test the hypothesis that ‘islands’ of fire-sensitive rain forest are restricted to topographic fire refugia and investigate the role of topography–fire interactions in fire-mediatedExpand

How do small savanna trees avoid stem mortality by fire? The roles of stem diameter, height and bark thickness
To recruit to reproductive size in fire-prone savannas, juvenile trees must avoid stem mortality (topkill) by fire. Theory suggests they either grow tall, raising apical buds above the flames, orExpand

Abrupt fire regime change may cause landscape-wide loss of mature obligate seeder forests.
Obligate seeder trees requiring high-severity fires to regenerate may be vulnerable to population collapse if fire frequency increases abruptly. We tested this proposition using a long-lived obligateExpand

Fire regimes of Australia: A pyrogeographic model system
Aim Comparative analyses of fire regimes at large geographical scales can potentially identify ecological and climatic controls of fire. Here we describe Australia’s broad fire regimes, and exploreExpand

Humid tropical rain forest has expanded into eucalypt forest and savanna over the last 50 years
Tropical rain forest expansion and savanna woody vegetation thickening appear to be a global trend, but there remains uncertainty about whether there is a common set of global drivers. UsingExpand

The interactive effect of temperature and humidity on the oxygen isotope composition of kangaroos
1. A strong relationship between the oxygen isotope composition (expressed as delta O-18) of body water and relative humidity has been demonstrated for a number of mammalian herbivores with lowExpand

Pyrodiversity is the coupling of biodiversity and fire regimes in food webs
Fire positively and negatively affects food webs across all trophic levels and guilds and influences a range of ecological processes that reinforce fire regimes, such as nutrient cycling and soilExpand

The carbon and nitrogen isotope composition of Australian grasses in relation to climate.
1. The carbon and nitrogen isotope composition of plants are known to be affected by environmental factors, especially water availability. While d13C of C4 plants is generally assumed to be muchExpand
