| deforestation and the spatio-temporal distribution of savannah and forest members of the simulium damnosum complex in southern ghana and south-western togo. | spatio-temporal data on cytotaxonomic identifications of larvae of different members of the simulium damnosum complex collected from rivers in southern ghana and south-western togo from 1975 until 1997 were analysed. when the data were combined, the percentages of savannah blackflies (s. damnosum sensu stricto and s. sirbanum) in the samples were shown to have been progressively increasing since 1975. the increases were statistically significant (p < 0.001), but the rates of increase were not li ... | 2002 | 12625139 |
