The effect of exogenous growth regulators on salinity tolerance in Erucastrum strigosum
(University of the Western Cape, 2003)
Randomized block experiments were conducted to examine the putative amelioratory
effects of kinetin or gibberellic acid at concentrations (0, 4, 12.5, 40, and 125 μM) in
Erucastrum strigosum plants subjected to a salinity ...
Empirical and model derived respiration responses to climate in different soils of an arid South African ecosystem
(2009)
This study examined the magnitude of soil CO2 efflux in an arid South African ecosystem, the flux responses as well as those of key limiting nutrients to soil temperature increases and moisture reductions consistent with ...
The relevance of fog and dew precipitation to succulent plant hydrology in an arid South African ecosystem
(2009)
Fog and dew interception and utilization by plant canopies remains one of the least
considered aspects of vegetation studies at any scale yet the few studies that have been conducted point to their considerable influence ...

Amphibian monitoring in Kakamega Forest, Kenya
(2007)
Since the late 1970 there has been increased concern of amphibian decline and extinction. Several causes for the worldwide declines have been suggested and include ultraviolet radiation, predation, pollution, climate change, ...
The relationship between sediment composition and infaunal polychaete communities along the southern coast of Namibia
(University of the Western Cape, 2005)
This study examined the relationship between sediment structure and infaunal polychaete communities off the southern coast of Namibia from two separate sets of data, and a total of ninety-two samples. It also examined ...
Impacts of the invasive reed Arundo donax on biodiversity at the community-ecosystem level
(University of the Western Cape, 2007)
Arundo donax is an invasive species that mostly impacts on sensitive riparian ecosystems. Arundo is also invasive in South Africa, though less is known about its ecology, biology, and impacts. Since California and the ...
Patterns of resource use by livestock during and after drought in a communal rangeland in Namaqualand
(University of the Western Cape, 2006)
Pastoralists in Africa have developed complex mechanisms by which they can alleviate the threat of drought. They practice mobility as one of the strategies to avoid the worst effects of natural stress and disperse grazing ...

(University of the Western Cape, 2005)
At a meeting of worl leaders at the United Nations Conference on Environment and Development in Rio de Janeiro in 1992, it was recognized that because of the tremendous increase in the size of the global populations (which ...
Testing the suitability of local seaweeds and formulated feed as a food source for abalone (Haliotis midae Linnaeus) in an Integrated Land-based Aquaculture System
(University of the Western Cape, 2008)
The direct methanol fuel cell or DMFC is emerging as a promising alternative energy
source for many applications. Developed and developing countries, through research, are
fast seeking a cheap and stable supply of energy ...
