Ecklonia maxima kelp forests along a thermal gradient: community composition and recovery from disturbance
(University of the Western Cape, 2017)
Climate change will influence species distributions, survival and ecosystem functioning, mostly
through changes in sea surface temperatures and storm disturbance. Species are expected to shift
poleward in response to ocean ...
How Do Teachers and Learners Navigate the Terrain of Ecology and What are the Associated Conceptual Understandings?
(University of the Western Cape, 2011)
This thesis relates the teaching of ecology in schools to the requirements of the National Curriculum Statements, Grades R-9 and Grades 10-12, for Natural and Life Sciences. It examines the conceptual understanding of the ...

Interannual changes in abundance and distribution of jellyfish along the west coast of South Africa
(University of the Western Cape, 2015)
Hydromedusae are mostly carnivorous planktivores that under ideal conditions can reproduce and accumulate to form dense masses of jellyfish, known as blooms. These jellyfish blooms may have various impacts on their surrounding ...
Studies on the ecology and taxonomy of nematodes of Saldanha Bay, South Africa
(University of the Western Cape, 2013)
Few studies of shallow water marine nematodes have been conducted around South Africa, and none from the west coast. Here, I analyse the composition of nematode communities from six stations along a 3 km transect in Saldanha ...
Spatia-temporal dynamics in land use and habitat fragmentation in the Sandveld, South Africa
(University of the Western Cape, 2010)
The Cape Floristic Region (CFR) in South Africa, is one of the world's five Mediterranean hotspots, and is also one of the 34 global biodiversity hotspots. It has rich biological diversity, high level of species endemism ...
The roles of intertidal marine gastropod shells as secondary substrate for macroalgae
(University of the Western Cape, 2014)
Primary space within the marine benthos is by far the most limited resource for which all sessile organisms must compete. It only ever becomes available when the organisms occupying it dies or are forced to leave the area. ...
