Abstract
Burgess, N., de Klerk, H., Fjeldsá, J., Crowe, T. & Rahbek, R. 2000. A preliminary assessment of congruence between biodiversity patterns in Afrotropical forest birds and forest mammals. Ostrich 71 (1 & 2): 286–291. Databases compiled for forest birds and forest mammals in the Afrotropics were tested for congruence of overall patterns and hotspots of species richness and endemism. We also looked at how well a near-minimum set of priority areas for one taxon catered for the second taxon. Overall species richness and richness hotspots of forest birds were significantly correlated with those of forest mammals, as was the case for overall endemism. Endemism hotspots for forest birds and mammals were not significantly correlated. The near-minimum set for forest birds represented 136 (76.5%) forest mammal species. The near-minimum set for forest mammals represented 350 (93.62%) forest bird species. However, to represent all forest mammals three times each, 51 grids were needed in addition to the 78 chosen as a near-minimum set for forest birds, and to represent all forest birds three times each, 43 more grids were needed in addition to the 80 selected for forest mammals. There is some congruence between the patterns of richness, endemism and near-minimum sets for forest birds and mammals in the Afrotropics, but the one taxon does not provide the ideal conservation solution for the other. Further refinement of the databases used in this paper would allow for more rigorous testing of congruence between these two groups.
