Facultative and Obligate Trees in a Mesic Savanna: Fire Effects on Savanna Structure Imply Contrasting Strategies of Eco-Taxonomic Groups Open
Fire is a major determinant of savanna tree communities and, as such, manipulation of fire frequency is an important management tool. Resolving the effects of fire management on tree size class distributions can help managers predict and p…
Defining the fire trap: Extension of the persistence equilibrium model in mesic savannas Open
Mesic savannas are dominated by trees that are strong resprouters caught in a frequent fire trap. Persistence within this fire trap has been described by a resprout curve of SizeNext ~ f(Pre‐fire size), defined by the Michaelis‐Menten func…
Variable rainfall has a greater effect than fire on the demography of the dominant tree in a semi‐arid <i>Eucalyptus</i> savanna Open
Rainfall, fire and competition are emphasized as determinants of the density and basal area of woody vegetation in savanna. The semi‐arid savannas of Australia have substantial multi‐year rainfall deficits and insufficient grass fuel to ca…
