Climatic And Environmental Change

In the autumn of 2004, a remarkable gathering of 102 scholars took place at St Antony's College, Oxford: they had come for an interdisciplinary symposium on ‘Trees, rain, and politics in Africa: the dynamics and politics of climatic and environmental change’. Symposium papers were grouped into panels that focused on either particular resources (such as trees and water) or particular aspects of social relationships (such as politics and discourses). This format resulted in a series of dialogues between the natural science and social science paradigms, and this first half of the present issue of Africa takes as its theme just one of those interdisciplinary conversations. Taken together, these authors demonstrate how the hybridization of natural science and social science can benefit understandings of the African past, interpretations of the African present and planning for the African future.1

Fouling Communities

Macroalgal fouling communities are potentially useful as bioindicators in environmental monitoring as they are considered to be sensitive to changes in environmental conditions and the use of artificial substrata facilitates the implementation of standardized sampling strategies. The response of macroalgal fouling communities on buoys to changes in water quality was investigated with a view to the possible utilization of these assemblages in environmental monitoring programmes. Seven study sites were selected based on previously collected environmental data and Principal Components Analysis (PCA) was used to order sites according to beam attenuation coefficient (BAC) and concentration of dissolved nitrates and phosphates, relative to a minimally impacted reference site. At each site, all fouling macroalgae were collected from 10 buoys of standard shape and size, and were identified to the lowest possible taxonomic level. Species composition and species dominance were highly variable among impacted sites, indicating that qualitative aspects of community structure may not be useful as indicators of changes in water quality. However, higher levels of nutrient enrichment and turbidity were associated with lower macroalgal species richness, lower overall abundances, and decreased diversities, and therefore these quantitative aspects of community structure are potentially useful as indicators of environmental change. Intermediate levels of turbidity and nutrient enrichment were associated with lower evenness, but did not influence species richness, suggesting that macroalgal abundances respond to changes in environmental conditions before species replacement occurs.
