- Description: Knowledge of the factors that drive species distributions provides a fundamental baseline for several areas of research including biogeography, phylogeography and biodiversity conservation. Data from 148 minimally disturbed sites across a large drainage system in the Cape Floristic Region of South Africa were used to test the hypothesis that stream fishes have similar responses to environmental determinants of species distribution. Two complementary statistical approaches, boosted regression trees and hierarchical partitioning, were used to model the responses of four fish species to 11 environmental predictors, and to quantify the independent explanatory power of each predictor.

- Description: South Africa is widely recognised as a highly diverse country with regard to its people, culture, landscapes, biological resources and ecology. The importance of policies on protecting cultural diversity and how they relate to the environment is only just emerging at an international level, but in South African we find there is a complete lack of institutional support for rural communities’ attachment to local landscapes. The main objective of this case study is to improve our understanding of the meanings and values that Xhosa people (amaXhosa) of the Eastern Cape Province of South Africa attach to their natural landscapes. It is clear that the amaXhosa are still intrinsically connected to their natural environment, in particular the thicket biome that is called ihlathi yesiXhosa (Xhosa forest). Access to places and spaces within the natural environment provides a sense of wellbeing, a link to ancestral spirits, a location for religious rituals, plus a wealth of culturallyinspired uses of specific species and sacred places in the landscape. We suggest that local cultural values could be incorporated into the formal conservation process.

Submission to Press Freedom Commission (PFC) on Media Self-regulation, Co-regulation or Statutory regulation in South Africa:

- Description: Prof Duncan has outlined the relative merits and demerits of self-regulation, co-regulation and deregulation, with which we are in broad agreement. She has also ably dealt with the three functions of regulatory bodies, namely the setting of ground rules for the industry to ensure best practice; enforcement of these; and adjudication of claims and counter claims re journalistic practice (Duncan 2012, p17). Finally, she has also taken up the issue of the necessity of accepting Third Party Complaints as one of the fundamental mechanisms by which citizens can make complaints on the basis of principle, rather than being personally aggrieved. While we are in broad agreement with her on these issues, we would like to highlight some further points for consideration.

Troubling White Englishness in South Africa:

- Description: To be white in Africa is to be part of a minority - but a very powerful minority. To be white in South Africa is to be implicated and complicit in historical dispossession and disenfranchisement. However, in post-apartheid South Africa, whiteness is no longer the invisible condition of the default human being, a condition to which all other humans must aspire. In fact, to be white is suddenly to be very visibly Other to the black African majority who are increasingly shaping the social landscape in ways that undermine the trajectories of both the colonial project and the apartheid project in this country.
