      Durand's () studies of the population dynamics of Alestes baremose supported earlier suggestions that this lake had distinct populations of this species. In Citharinus citharus,first-yeargrowth was found to be very variable in the Chari-Logone; growth stopped November-March when the water temperature fell below 25°C (Benech, ).

The species included two snake species, Two Lizard species, one skink, and one gecko. The occurrence of the Forest Cobra Naja melanoleuca, Nile Monitor Varanus niloticus, and Central Africa Rock Python Python sebae was reported by the community.

A full list of species recorded during the survey is shown below in table Full text of "Current bibliography for aquatic sciences and fisheries" See other formats. Moreover, the data of Acere () allowed a fitting with the VBGF as modified by Soriano et al. () taking into account a two phase growth curve for juveniles and adults as shown on Fig.

This new curve can be assumed to result from two different growth patterns as shown in Fig. Full text of "The Uganda protectorate; an attempt to give some description of the physical geography, botany, zoology, anthropology, languages and history of the territories under British protection in East Central Africa, between the Congo Free State and the Rift Valley and between the first degree of south latitude and the fifth degree of north latitude".

Thus, without the need to return to rivers for breeding, as do anadromous fïshes (Lowe-McConnell,), a cichlid population may adapt to the conditions of a single habitat only, which is presumably conducive to ecological specialization and to speciation of allopatric populations.

Two important documents onglobal plant biodiversity have been published in recent years, Centres of plant diversity, in three volumes(WWF & IUCN, ), and the IUCN Red list of threatened plants (Walter & Gillett).

About 78% of the world’s plants are tropical (the zone between the Tropic of Cancer and theTropic of Capricorn). The book opens with an overview of the ecology of tropical freshwater and marine environments and their associated fish faunas, and then presents a number of freshwater studies drawn from the African, South American, Asian and New Guinea tropics.

Special consideration is given to the new man-made lakes which have provided large-scale. An active breeding colony of the suitable snail host was established to provide a steady supply of cercariae for goats infection. The effect of experimental Schistosoma bovis infection on the clinical and pathological alternations was investigated in male goats (month old).
