How do small savanna trees avoid stem mortality by fire? The roles of stem diameter, height and bark thickness
- M. Lawes, H. Adie, J. Russell-Smith, B. Murphy, J. Midgley

- 1 April 2011
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, or… Expand
The heat is on: frequent high intensity fire in bracken (Pteridium aquilinum) drives mortality of the sprouting tree Proteacaffra in temperate grasslands

We examined the effect of fire frequency and intensity on a Protea caffra tree population in the temperate montane grasslands of north-western KwaZulu-Natal, South Africa. We assessed the effect of… Expand
Podocarpaceae in tropical forests: A synthesis
- L. Cernusak, H. Adie, +13 authors Benjamin L Turner
- Geography
- 14 October 2011
The Podocarpaceae comprises 18 genera and about 173 species of evergreen, coniferous trees and shrubs. It is the most successful gymnosperm family in angiosperm-dominated tropical forests (Brodribb,… Expand
Explaining conifer dominance in Afrotemperate forests: Shade tolerance favours Podocarpus latifolius over angiosperm species
Abstract We contrasted the regeneration success of angiosperm canopy species with that of Podocarpus latifolius to test whether this conifer was sufficiently shade tolerant to be favoured on… Expand
Regeneration dynamics in arid subtropical thicket, South Africa

- Biology
- 1 September 2013
Abstract In arid environments nurse-plants modify localised habitats and create regeneration opportunities for seedlings vulnerable to hostile conditions created by biotic and abiotic factors.… Expand
Role reversal in the stand dynamics of an angiosperm-conifer forest: Colonising angiosperms precede a shade-tolerant conifer in Afrotemperate forest
Abstract In mixed angiosperm–conifer forests worldwide, infrequent landscape-level catastrophic disturbances create a mosaic of persistent and different aged forest stands in the landscape with… Expand
Pervasive, long-lasting impact of historical logging on composition, diversity and above ground carbon stocks in Afrotemperate forest

- Geography
- 15 December 2013
Abstract Understanding the rate and extent of forest recovery from major disturbance events enable forest managers to establish conservation priorities and allocate limited resources for their… Expand
Small fire refugia in the grassy matrix and the persistence of Afrotemperate forest in the Drakensberg mountains

- Geography, Medicine
- Scientific Reports
- 26 July 2017
Afrotemperate forests situated in the Drakensberg mountains of South Africa are characteristically small (1–10 s ha) and widely dispersed in a vast fire-prone grassland. Compared with lowland… Expand

Podocarps in Africa: Temperate Zone Relicts or Rainforest Survivors?
Podocarp distribution in Africa follows a discontinuous mountainous belt from Cameroon to Angola in the west and from Ethiopia in the northeast to the southern Cape in South Africa. Besides a relict… Expand
