Detecting patterns of upwelling variability in Eastern Boundary Upwelling Systems with special emphasis on the Benguela region
(University of Western Cape, 2020)
Coastal upwelling is one of the most important oceanographic processes relating to ecosystem function at local and global spatial scales. To better understand how changes in upwelling trends may occur in the face of ongoing ...
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 ...
Quantifying competition in two co-occurring southern African psammophiinae snakes: Psammophis crucifer and psammophylax r. Rhombeatus
(University of Western Cape, 2020)
Studies on snake competitive interactions have relatively been well documented globally, however, those examples tend to be dominated by non-African examples. Africa has a large and spectacular reptile diversity and yet ...
Towards an unravelling of the taxonomy of Chrysaora (Scyphozoa; Semaeostomeae; Pelagiidae) from around South Africa
(University of the Western Cape, 2017)
Historically, two species of Chrysaora are known from the Benguela Current Ecosystem: C.fulgida (Reynaud 1830) and C. africana (Vanhöffen 1902). However a third morphotype is now seen, which bears a resemblance to both. ...
A web-based biodiversity toolkit as a conservation management tool for natural fragments in an urban context
(University of the Western Cape, 2016)
The collection of biological information has a long history, motivated by a variety of reasons and in more recent years is largely being driven for research and academic purposes. As a result biological information is often ...
Blood cell histology of Homopus areolatus: effects of season and cohort
(University of the Western Cape, 2015)
Homopus areolatus is an endemic terrestrial tortoise that resides in a Mediterranean type of climate, which is characterised by winter rainfall and mild winter temperatures. Within ectotherms, such as H. areolatus, ...
Assessing the vegetation and soil microbial ecology of renosterveld rangelands around Nieuwoudtville, Northern Cape Province
(University of the Western Cape, 2015)
The Bokkeveld Plateau, a region hosting high plant endemism, is home to two arid mountain centre renosterveld types. One, Nieuwoudtville Shale Renosterveld, has partially been transformed into croplands and pastures, with ...
Effects of season and cohort on the haematology of the geometric tortoise Psammobates geometricus.
(University of the Western Cape, 2012)
The geometric tortoise is one of the world‟s rarest terrestrial tortoises and is endemic to the Southwestern Cape, South Africa. There has been cause for conservation concern for Psammobates geometricus, yet as is common ...
Valuing the natural resources and ecosystem services of Leliefontein communal rangeland in Namaqualand, South Africa.
(University of the Western Cape, 2014)
Natural resources play important roles in ecosystem service delivery, more especially in rural households where livelihoods depend heavily on natural resources for the delivery of ecosystem services. The various benefits ...
Monitoring water quality with riparian trees along the Berg River, Western Cape
(University of the Western Cape, 2012)
Heavy metals and nutrients have long been regarded as pollutants to freshwater ecosystems. These elements have a detrimental effect on plants, animals and the water quality of rivers in South Africa. The Berg River flows ...
