Above-ground allometry, biomass and nutrient content of acacia mearnsii across four ages and three sites in the Kwazulu-Natal Midlands.
Acacia mearnsii (black wattle) is one of the few tree crops of which both timber and bark are utilised, with branches sometimes being collected for fuel wood. There is a great potential for nutrient loss from plantations ...
Role of light and temperature in the flowering of Watsonia species.
The role of light and temperature on flowering of South African Watsonia species were evaluated to assess the potential for this genus as a commercial flower crop. Species were selected that represent different climatic ...
Regeneration failure and the Acacia karroo successional pathway in coastal dune forests in KwaZulu-Natal, South Africa.
Monospecific stands of Acacia karroo establish naturally on disturbed coastal dunes in KwaZulu-Natal, South Africa. While the A. karroo successional pathway is successful in rehabilitating mined dunes at the Richards Bay ...
Host specificity of the hemiparasitic mistletoe, Agelanthus natalitius.
Mistletoes are a group of hemiparasitic plants that grow on a wide variety of host trees and differ in their degree of host specificity, ranging from specialists to generalists. Mistletoes can also be locally host specific ...
Some physiological and growth responses of three eucalyptus clones to soil water supply.
The response of three Eucalyptus spp. clones (GC550, GU210 and TAG14) to water availability was assessed in terms of growth, plant water status, leaf gas exchange, whole plant hydraulic characteristics (both root and ...
Some implications of associated mycoflora during hydrated storage of recalcitrant seeds of Avicennia marina (Forssk.) Vierh.
Three questions are considered in the context of the possible effects of seedassociated mycoflora, typified by Fusarium moniliforme, during hydrated storage of recalcitrant seeds of the tropical species, ...
The application of microsatellites to sugarcane parentage determination and varietal identification.
The use of microsatellite markers has matured and become commonplace for plant genome analyses and is now poised for widespread practical application in sugarcane. Sequence Tagged Microsatellite Site (STMS) amplification ...
Patterns, mechanisms and evolution of avian facultative hypothermic responses : a southern African perspective.
Recent evidence suggests that avian facultative hypothermic responses are more common than previously thought. Traditionally, several categories of avian hypothermic responses have been recognized, and are frequently ...
Systematic revision of Southern African species in the genera Eptesicus, Neoromicia, Hypsugo and Pipistrellus (Chiroptera: Vespertilionidae).

Seed germination and medicinal properties of Alepidea species.
The rhizomes of Alepidea amatymbica and Alepidea natalensis are used for medicinal purposes. Because of the increase in demand for these plants the species is becoming scarce. As the seed biology of neither species is well ...
