This study examines how South Africans construct and negotiate racial identities in written commentaries via a forum of the Mail@Guardian website Thought Leader in response to a blog by Ndumiso Ngcobo entitled “I’m a coconut and I am proud of it – say it with me.” Ngcobo’s ironic opinion piece, written in 2008, which plays with the label “coconut” (frequently employed in South Africa among “black” people in reference to another “black” person who seemingly behaves “white”), triggered 163 responses from individual readers. An essential point made by Ngcobo is that perceptions and attitudes around “whiteness” and “blackness,” or what can be considered “white” or “black” in racial terms, vary greatly, depending on circumstances and perspective. However, the author’s irreverent and ironic style is misunderstood and misinterpreted by many of the comment writers. Relying partially on the methodological framework of Critical Discourse Analysis, I analyze the commentary texts and interpret the categories people use in their discursive constructions of race and identity by examining their stylistic choices and content markers and focusing on sociolinguistic and cultural issues. It is argued that the analyzed comments are representative not only of the pervasiveness of “rigid” race thinking but also of how intra-racial boundaries are constructed in the post-apartheid state.
The sequence diversity in the mitochondrial cytochrome-c oxidase I (COI) gene was evaluated as a tool for resolving differences among species of European adelgids collected from several localities across the Czech Republic. Members of 7 genera and 16 species were examined, and as outgroups, two species of Phylloxeridae were used. Sequence divergences within species were on average less than 0.15%, whereas divergences between species ranged from 0.0 to 4.12% for congeneric and to 13.24% for intergeneric comparisons. It is concluded that DNA barcoding of Adelgidae is a powerful tool for identifying genera, but at the species level it works only in those cases where there are no species complexes. Nevertheless, it can be used as a complement to traditional, morphological taxonomy.
