The influence of climate change on the distribution of indigenous forest in KwaZulu‐Natal, South Africa
Aims (1) To define the physical correlates of indigenous forest in KwaZulu‐Natal province and develop a model, based on climatic parameters, to predict the potential distribution of forest subtypes
Resprouting as a key functional trait: how buds, protection and resources drive persistence after fire.
A buds-protection-resources (BPR) framework for understanding resprouting in fire-prone ecosystems, based on bud bank location, bud protection, and how buds are resourced is developed, which provides insights into resprouted typologies that include both fire resisters and fire resprouters.
The distribution of the samango monkey (Cercopithecus mitis erythrarchus peters, 1852 and Cercopithecus mitis labiatus I. Geoffroy, 1843) and forest history in southern Africa

It is suggested that southern African forest mammals followed two possible routes relating directly to the timing, and extent of development, of Afromontane and Indian Ocean Coastal Belt forest respectively, in the south- ern African subregion in the past.
Do food availability, parasitism, and stress have synergistic effects on red colobus populations living in forest fragments?
A path analysis suggests that change in food availability has a strong direct effect on population size, but it also has an indirect effect via parasite infections.
Multiple Receivers, Multiple Ornaments, and a Trade‐off between Agonistic and Epigamic Signaling in a Widowbird
It is proposed that the “multiple receiver hypothesis” can explain the coexistence of multiple handicap signals, and the trade‐off between signal expressions might contribute to the inverse relation between nuptial tail elongation and coloration in the genus Euplectes (bishops and widowbirds).
Resilient forest faunal communities in South Africa: a legacy of palaeoclimatic change and extinction filtering?
The response of vertebrate taxa to large-scale, historical processes is dependent on their relative mobility: forest birds best illustrate patterns resulting from post-glacial faunal dispersal, while among mammals and frogs the legacy of climatic extinction filtering remains stronger.
Agonistic carotenoid signalling in male red-collared widowbirds: aggression related to the colour signal of both the territory owner and model intruder
It is shown that sexually dimorphic carotenoid ornamentation functions as an agonistic signal in male red-collared widowbirds, Euplectes ardens, suggesting that the nuptial carotanoid coloration is an honest signal of dominance or fighting ability, sexually selected through male contest competition over territories.
Savanna woody plant dynamics: the role of fire and herbivory, separately and synergistically
A synthesis of recent literature suggests that in some cases herbivory alone can be more significant than fire alone, on woody plant population size, that fire and Herbivory together are a lethal combination for woody plants and that differences in strategies and responses of savanna plants to fire and herbsivory are poorly explored.
