The Mammals of Nigeria.

402 Seiten, 20 Bildtafeln mit 2/w-Photos, zahlreiche Strichzeichungen.

Oxford University Press. Oxford, New York, Toronto.
ISBN 0-19-8575653.

Anbietertext:

Both a field guide and a reference work, this book is the first comprehensive account of all 250 species of mammals recorded in Nigeria. The first part describes each species in detail with information on distribution, identification, status, ecology, reproduction, and taxonomy, with keys provided for easy identification of each species. Following chapters consider the ecological relationships of Nigerian mammals, zoogeographical patterns and ecological trends, and interactions between humans and mammals. Written with a minimum of technical terms and filled with photographs, drawings, and maps, this book is a fascinating and useful work for anyone intererested in African mammals.

EATON, M.J. (2010)

Dwarf Crocodile - Osteolaemus tetraspis.

In: Crocodiles.Status Survey and Conservation Action Plan: 127-132.
Third Edition, ed. by S.C. Manolis and C. Stevenson. Crocodile Specialist Group: Darwin.

Aus dem Inhalt:

The African dwarf crocodile historically ranged throughout the lowland regions of West and western Central Africa, from Senegal and The Gambia in the west to the eastern border of the Congo Basin in the Democratic Republic of Congo and Uganda. Northern Nigeria and Cabinda Province (Angola) are considered to be the northern and southern extents of the genus, respectively. The Central and West African dwarf crocodile (O. tetraspis) is now distinguished from Osborn’s dwarf crocodile (O. osborni), and new research suggests that populations further west are signifi cantly differentiated from lineages in Central Africa and the Congo Basin and warrant a unique species designation (Osteolaemus cf. tetraspis) (Eaton et al. 2009).

The taxonomy of the African dwarf crocodile has been under debate for almost 80 years. Osteolaemus tetraspis was first described in 1860 from Gabon. A second morphological form, discovered in the upper Congo River Basin, was described as a new genus (Osteoblepharon osborni, Schmidt 1919). This new genus was subsequently considered to be unwarranted, resulting first in osborni being relegated as species of Osteolaemus and then to a subspecies, Osteolaemus tetraspis osborni (Wermuth 1953). Some authorities have even suggested that sub-species status may not be merited. A recent morphological study, however, has confirmed fixed differences between tetraspis and osborni, suggesting that each should be resurrected as a distinct taxon. Additionally, a recent molecular  phylogenetic analysis of samples collected from the Republic of Congo, Gabon, Ivory Coast and Ghana supports the evolutionary distinctiveness of dwarf crocodiles in the Congo Basin (osborni) from those further west. This same investigation also revealed that the nominal form of O. tetraspis from Gabon’s Ogooué Basin is genetically distinct from dwarf crocodiles in West Africa, suggesting that at least one new morphologically cryptic species exists in the latter region.

Comparative ecology of the African pike, Hepsetus odoe, and tigerfish, Hydrocynus forskahlii, in the Zambezi River floodplain.

Journal of Fish Biology 45 (2): 211–225, August 1994. DOI: 10.1111/j.1095-8649.1994.tb01301.x

Abstract:

The ecology of sympatric African pike, Hepsetus odoe (Hepsetidae), and tiger fish, Hydrocynus forskahlii (Characidae), were compared during high (May-August) and falling water (September-December) conditions in the Upper Zambezi R. drainage of Zambia. Both species were common in the central and southern regions of the river and associated floodplain, and Hydrocynus was common in the northern region in swift flowing tributaries where Hepsetus was rare. Hepsetus inhabited vegetated environments of river backwaters, lagoons, and sluggish tributaries, whereas Hydrocynus occupied the open water of the main river channel almost exclusively. During the period of annual flooding, juveniles of both species coexist in flooded savanna regions. Size distributions of adult Hydrocynus and Hepsetus changed relatively little between high and low water conditions. Stomach contents analysis indicated that adult size classes of both species are almost entirely piscivorous, and both show diet shifts with changes in size. Only very small seasonal diet shifts were noted. Approximately 50% of the diet of Hepsetus consisted of haplochromine cichlid fishes, but also included large numbers of tilapine cichlids and mormyrids, Hydrocynus consumed primarily cichlid fishes, but also consumed large percentages of Hepsetus and small characid fishes. Small size classes of Hepsetus fed heavily on small machokid catfishes (Synadontis spp.) and later shifted to a diet of cichlids and mormyrids, and small Hydrocynus preyed heavily on Barbus spp. (Cyprinidae), small characids, and mormyrids. Ratios of prey length-predator length averaged approximately 0·26 for Hydrocynus and nearly 0·40 for Hepsetus. The large potential for food resource competition appears not to be realized due to a very high degree of habitat partitioning between larger size classes of the two species. At the interface between river backwaters and channel habitats, Hydrocynus is a significant predator of Hepsetus, a factor that should further restrict the occurrence of the latter in open areas of the main channel.

SCOTT McGRAW, W. (1998)

Three monkeys nearing extinction in the forest reserves of eastern Côte d'Ivoire

ORYX 32 (3): 233-236. ISSN 0030-6053. DOI 10.1046/j.1365-3008.1998.d01-48.x

Abstract:

Surveys were carried out in forest reserves in eastern Côte d'Ivoire in 1997 to investigate the status of three primate taxa believed to be on the verge of extinction. The findings indicate that Procolobus badius waldroni may be extinct, and that Cercopithecus diana roloway and Cercocebus atys lunulatus may become so unless urgent action is taken.

Der Viktoriasee. Kenya-Uganda-Exkursion vom vom 27. Februar bis 31. März 1999.

Universität Trier.

http://www.ostafrika-forschung.de/1999/start.htm (NB: Diese Internetseite ist nicht mehr verfügbar)

Einleitung:

Im Rahmen des Studiums der Geographie führte für 16 afrikabegeisterte Studenten der Universität Trier der Weg nach Ostafrika. Vom 27. Februar  bis 31. März 1999 bereisten sie unter der Leitung von PD Dr. Berthold Hornetz und Dipl.-Geogr. Dietmar Zühlke Kenya und mit einem  "Abstecher" Uganda. Während dieser Exkursion sahen sie großartige Landschaften in Kenya und Uganda, trafen die unterschiedlichsten Stadt- und Landmenschen und beschäftigten sich mit den verschiedensten Problemen ostafrikanischer Entwicklungsländer anhand einzelner Beispiele. Die Ergebnisse sind auf dieser CD-ROM zusammengetragen worden. Diese Zusammenstellung soll sowohl dem Interessierten ermöglichen sich über geographisch relevante Themen zu informieren, als auch bei Teilnehmern und Teilnehmerinnen Erinnerungen wecken an die fachlich fruchtbare und schöne Zeit, die sie dort miteinander verbracht haben.
