The present geological period has more species than any other, yet the current rate of extinction of species is greater now than at any time in the past. Ecosystems and communities are being degraded and destroyed, and species are being driven to extinction. The species that persist are losing genetic variation as the number of individuals in populations shrinks, unique populations and subspecies are destroyed, and remaining populations become increasingly isolated from one another. The cause of this loss of biological diversity at all levels is the range of human activity that alters and destroys natural habitats to suit human needs.” (Primack, 2002). CapeNature launched its State of Biodiversity Programme (SoBP) to assess and monitor the state of biodiversity in the Western Cape in 1999. This programme delivered its first report in 2002 and these reports are updated every five years. The current report (2007) reports on the changes to the state of vertebrate biodiversity and land under conservation usage.

Box 336, Hawassa University, Hawassa, Ethiopia (*[email protected]). 2Department of Biology, College of Natural and Computational Sciences, P.O. Box 5, Hawassa University, Hawassa, Ethiopia. ABSTRACT Diet composition and trace metal concentration in the muscle of the lapping minnow Garra quadrimaculata (Rüppell, 1835) was investigated to study the trophic status of the species as well as to assess the level of bioaccumulation of heavy metals in the body of the fish. The study was conducted based on 328 gut samples collected from February to March (dry months) and from August to September (wet months) of the year 2011. Frequency of occurrence and volumetric methods were employed in this study. Detritus, fish eggs, macrophytes, phytoplankton and insects occurred in 54.9%, 16.2%, 43.9%, 56.4% and 26.6% of the guts, respectively and comprised 27.1%, 22.2%, 18.2%, 18.2% and 14.1% of the total volume of food, respectively. The proportions of different food items consumed varied during the dry and wet months. Fish eggs and detritus were the dominant food items during the dry months. Macrophytes and insects were also common in the diet. During the wet months, phytoplankton was the most dominant food item (33.5% by volume). Macrophytes, detritus and insects were also important in the diet.

    Out of Lake Tanganyika: Endemic Lake Fishes Inhabit Rapids of the Lukuga River

    355 Ichthyol. Explor. Freshwaters, Vol. 22, No. 4, pp. 355-376, 5 figs., 3 tabs., December 2011 © 2011 by Verlag Dr. Friedrich Pfeil, München, Germany – ISSN 0936-9902 Out of Lake Tanganyika: endemic lake fishes inhabit rapids of the Lukuga River Sven O. Kullander* and Tyson R. Roberts** The Lukuga River is a large permanent river intermittently serving as the only effluent of Lake Tanganyika. For at least the first one hundred km its water is almost pure lake water. Seventy-seven species of fish were collected from six localities along the Lukuga River. Species of cichlids, cyprinids, and clupeids otherwise known only from Lake Tanganyika were identified from rapids in the Lukuga River at Niemba, 100 km from the lake, whereas downstream localities represent a Congo River fish fauna. Cichlid species from Niemba include special- ized algal browsers that also occur in the lake (Simochromis babaulti, S. diagramma) and one invertebrate picker representing a new species of a genus (Tanganicodus) otherwise only known from the lake. Other fish species from Niemba include an abundant species of clupeid, Stolothrissa tanganicae, otherwise only known from Lake Tangan- yika that has a pelagic mode of life in the lake. These species demonstrate that their adaptations are not neces- sarily dependent upon the lake habitat. Other endemic taxa occurring at Niemba are known to frequent vegetat- ed shore habitats or river mouths similar to the conditions at the entrance of the Lukuga, viz. Chelaethiops minutus (Cyprinidae), Lates mariae (Latidae), Mastacembelus cunningtoni (Mastacembelidae), Astatotilapia burtoni, Ctenochromis horei, Telmatochromis dhonti, and Tylochromis polylepis (Cichlidae). The Lukuga frequently did not serve as an ef- fluent due to weed masses and sand bars building up at the exit, and low water levels of Lake Tanganyika.
