From his personal research undertaken in the subterranean field (natural and artificial cavities) in Shaba (ex-Katanga, in S.E. Zaire) and Rwanda, the author briefly defines the macroclimate of the prospected regions as well as the microclimate of the subterranean habitat (humidity and temperature). A reversible hypothermia has been noticed in the dry season only (from May till August) in eleven species of troglophile Chiroptera belonging to the following families: Rhinolophidae (7 species of Rhinolophus), Hipposideridae (only Hipposideros ruber) and Vespertilionidae (Miniopterus inflatus rufus, Miniopterus schreibersi arenarius & M.s. natalensis, Myotis tricolor). No sign of lethargy has been noticed in the Megachiroptera (Lissonycteris angolensis, Rousettus aegyptiacus leachi), Emballonuridae (Taphozous perforatus sudani), Hipposideridae (Cloeotis percivali australis) or Nycteridae (3 species of Nycteris). There could be correlations between lethargy and breeding if one takes into account the phenomena of late ovulation and delayed implantation. The entry into lethargy is not caused by the scarcity of food. It does not concern all the individuals of a colony or in various populations of a cave. The degree of humidity appears to be more important than the temperature as far as the conditions for hibernation are concerned.
After a brief analysis of the elements of the cavernicolous microclimate in Shaba, the author emphasizes the possibility of relations between ecology and parasitism. He then reviews the 9 species of Chiroptera that live in the subterranean field in Shaba, pointing out their environmental habitat. behaviour and parasites.
LIMESTONE FORMATIONS, KARSTS, AND CAVES IN SHABA PROVINCE (ZAIRE) - Zaire have numerous Precambrian carbonated formations, especially in the Shaba district. Both "Kakontwe" and "Lubudi" limestones, with large outcrops and tectonic porosity are favourable for cave genesis.
Une morphologie karstique typique en zone intertropicale : les karsts du Bas Zaïre, 1985,
Quinif, Y.
A TYPICAL MORPHOLOGY OF TROPICAL KARSTS: THE KWILU BASIN IN THE LOWER-ZAIRE - The Kwilu basin, in the region of Bas-Zaire, shows typical landscapes of tropical karsts: cone and tower karsts shaped in precambrian limestones of the "Groupe schisto-calcaire". These precambrian series are little tectonised. They are covered with cenozoic formations which are important in the evolution of the karst. Different types of cavities are studied and replaced in the morphostructural context: old caves, originating in phreatic zone and now cut by the erosion, river streams in tunnel-caves, network under the water table. The superficial forms are interpreted as successive evolutive steps: dissection of a surface (morphological or structural) by a dendritic hydrographic network, birth of a cone-karst being transformed in tower-karst overlooking a new surface. We insist on the morphogenetic importance of the paleoclimatic changes and on the existence of an intertropical karstic morphology in stable craton.
Morphology and hydrology of a covered karst: the Ziaka cave-system (Lower Zaïre) - In the middle of the Lower Zaïre karst, Ziaka cave constitutes the emergence of a great flooded karst. Divers have explored several flooded galleries. The cave shows very characteristic morphology of flooded karst: coupolas, bedding-plane anastomosis. The river deposits of the Kwilu cover the limestone. The karst is capped and artesian, its water table is higher than the base level of the Kwilu.
The Kisanga iron caps in Southern Shaba (Zaire), situated in the Kakontwe limestone, results from the filling of an Upper Proterozoic paleokarst. These ancient karstic traces have been related to a local and temporary emergence in the Likasi district caused by the Kipushi rift structuration during the early Lower Kundelungu.
