The chemistry of acacia gums
… to the Rosaceae and Leguminosae families. Acacia trees belong to the Leguminosae family, and the exudate from a variety of acacia species is known as "gum arabic" or "gum acacia". Gum arabic is collected for industrial use from acacia trees grown in hot, dry climates. The most esteemed …

Invasion of coastal Acacia communities by Chrysanthemoides
… in displacement of the previous dominant, Acacia longifolia var. Sophorae (coastal wattle). In South Africa, closely related Acacia ssp. Are invasive, so a study of both Chrysanthemoides and Acacia provided a means of better understanding the invasion process. The main factors in the …

Spatial and temporal variability in Acacia population dynamics
… of a suite of common African savanna trees, the Acacia, in a landscape context. I carried out my field work in Hluhluwe iMfo lozi Park in KwaZulu Natal, South Africa, during 2006 and 2007. Fire, herbivory, and the grass layer were primary determinants of distributions and co-occurrence of Acacia …

The successional dynamics of Acacia nilotica (L.) savanna
… of seedlings is significantly higher below Acacia canopies than in open spaces. Size class data indicate that the largest Euclea individuals are found in open spaces and not below A. nilotica canopies. Because Eucleas have slower growth rates than A. nilotica, the large Eucleas may well have …

Birds as a dispersal agent for Acacia cyclops
The aims of this study were to: 1) estimate the quantity of seeds taken by birds in relation to the seed production of A. cyclops; 2) determine any selective feeding preferences for A. cyclops seeds, using Cape Turtle doves (Streptopelia capicola); 3) estimate the calorific utilization by Cape …

Attributes that make Acacia karroo dominant : stable N and C isotope analysis of nine Acacia species from KwaZulu-Natal (South Africa)
This study focuses on nine Acacia species from Hluhluwe-Imfolozi Park in KwaZulu-Natal, South AFrica. The study was motivated by the need to understand the dominance of legumes in the process of bush encroachment in Southern Africa. A. karroo has been identified as a particularly invasive species …

Why do wasp induced galls of Acacia longifolia photosynthesise?
… of bud galls induced by the wasp, Trichilogaster acaciae longifoliae (Pteromalidae) in the invasive Acacia longifolia. The role of this photosynthetic activity was examined in terms of its ability to subsidise carbon budgets, as well as to provide O₂ to the larvae and consume CO₂ in the dense gall …

Systematic and evolutionary studies of Acacia series Gummiferae (Fabaceae: Mimosoideae)
Study of the evolution and systematics of Acacia series Gummiferae encompassed revision of a subset of the New World members of the series that are endemic to the West Indies, a cladistic analysis of chloroplast DNA restriction site variation of members of Acacia series Gummiferae and related taxa, …
