African Biodiversity: Molecules, Organisms, Ecosystems by Bernhard A. Huber

By Bernhard A. Huber

In might 2004, the Alexander Koenig Zoological examine Museum hosted the 5th foreign Symposium on Tropical Biology. This sequence used to be proven on the ZFMK within the early Eighties, and has variably interested in systematics and ecology of tropical organisms, with an emphasis on Africa. past volumes are these edited by means of Schuchmann (1985), Peters and Hutterer (1990), Ulrich (1997), and Rheinwald (2000). The symposium in 2004 was once prepared through the Entomology division lower than the course of Michael Schmitt. The goal was once to target Africa instead of on a selected taxon, and to focus on biodiversity in any respect degrees starting from molecules to ecosystems. This concentration was once well timed in part as a result of presently operating BIOTA Africa programmes (BIOdiversity tracking Transect research in Africa). BIOTA is an interdisciplinary study venture concentrating on sustainable use and conservation of biodiversity in Africa ( consultation titles have been Biogeography and Speciation approaches, Phylogenetic styles and Systematics, range Declines and Conservation, and utilized Biodiversity Informatics. every one consultation used to be opened via an invited speaker, and all jointly seventy seven lectures and fifty nine posters have been provided. there have been over two hundred individuals and it used to be pleasant to us to fulfill colleagues from 26 countries, together with Russia, Ukraine, Japan, united states, and ten African nations. We thank all members for his or her priceless contributions.

S. : The Natural History Museum, London; Zimbabwe: Natural History Museum of Zimbabwe, Bulawayo. 3 Georeferencing All records of sufficient accuracy were collated to create a point locality geographical dataset for mapping distributional ranges. Only a small proportion of the records were initially accompanied by geographical coordinates or quarter-degree squares (QDS). 7 km2) were used preferentially, whenever possible, owing to their high level of spatial resolution. All such localities were, in turn, converted to decimal-degree format for GIS input.

It is exactly the avoidance of duplicated conservation efforts that is the advantage of the complementarity analysis! 4. 1 Strengths of the complementarity approach The coarse-scale distribution maps (Fig. 1, left) are range-maps, which tell little about finer distributional details or local distribution gaps. In spite of the potential problems with using such data (p. 3), our analysis reveals that the priority areas chosen from such data contain confirmed records of 99% of all forest birds of the region.

The number of cells in the near-minimum set determined with coarse-scale (onedegree) and interpolated distributional data, in which there are confirmed distribution records of the individual species. Dark columns: near-minimum set calculated for single representation of all species; light columns with flexible alterative also taken into account. 7% of all species considered, the minimum set included populations interconnected with other populations across at least three onedegree cells. 2% of the species, the minimum set contained only isolated populations (often a tiny cluster of adjacent 15’ cells), of which 1/3 are local populations inside a broader range and 2/3 represent species whose entire global range consist of small local populations.
