Cichlid Diversity, Speciation and Systematics: Examples from the Great African Lakes
Cichlid diversity, speciation and systematics: examples from the Great African Lakes Jos Snoeks, Africa Museum, Ichthyology- Cichlid Research Unit, Leuvensesteenweg 13, B-3080 Ter vuren,.Belgium. Tel: (32) 2 769 56 28, Fax: (32) 2 769 56 42(e-mail: [email protected]) ABSTRACT The cichlid faunas of the large East African lakes pro vide many fascina ting research tapies. They are unique because of the large number of species involved and the ir exceptional degree ofendemicity. In addition, certain taxa exhibit a substantial degree of intra~lacustrine endemism. These features al one make the Great African Lakes the largest centers of biodiversity in the vertebrate world. The numbers of cichlid species in these lakes are considered from different angles. A review is given of the data available on the tempo of their speciation, and sorne of the biological implications of its explosive character are discussed. The confusion in the definition of many genera is illustrated and the current methodology of phylogenetic research briefly commented upon. Theresults of the systematic research within the SADC/GEFLake Malawi/NyasaBiodiversity Conservation Project are discussed. It is argued that systematic research on the East African lake cichlids is entering an era of lesser chaos but increasing complexity. INTRODUCTION The main value of the cichlids of the Great African Grea ter awareness of the scientific and economi Lakes is their economie importance as a readily cal value of these fishes has led to the establishment accessible source of protein for the riparian people.

Two crude proteins (38%CP and 56%CP) and two crude lipids (9%CL and 16%CL) rates were applied to four formulated diets: R1 (38%CP:16%CL), R2 (38%CP:9%CL), R3 (56%CP:16%CL) and R4 (56%CP:9%CL). The SR was 100% in H. ahli while that of P. socolofi ranged from 66.6% to 93.3% in the two groups, respectively. The highest WG and SGR were seen in the H. ahli and P. socolofi groups fed with R2 feed. The best FCR values were obtained in R2 groups of H. ahli (1.64) and R groups of P. socolofi (1.41).

Testing Conjectures About Morphological Diversity in Cichlids of Lakes Malawi and Tanganyika
Copeia, 2005(2), pp. 359±373 Testing Conjectures about Morphological Diversity in Cichlids of Lakes Malawi and Tanganyika PROSANTA CHAKRABARTY The morphological diversity of Malawi and Tanganyika cichlids has often been qualitatively described, but rarely have hypotheses based on these descriptions been tested empirically. Using landmark based geometric morphometrics, shapes are an- alyzed independent of other aspects of the body form (e.g., size). The estimation of shape disparity, the quantitative measure of the variance of these raw shapes, can then be applied in order to objectively test hypotheses about morphological diver- sity. The shape disparity within and between different groups is explored as well as how it is partitioned within the cichlid body. Tanganyika cichlids are found to have signi®cantly greater shape disparity than Malawi cichlids. Ectodini is found to have signi®cantly greater shape disparity than other Great Lake tribes. Piscivorous cich- lids are signi®cantly more disparate in shape than cichlids with other diets, and the shape disparity of the cranial region was signi®cantly greater than that of the post- cranial region. ``We begin by describing the shape of an object in Lake cichlids have been described (Bouton et the simple words of common speech: we end by al., 2002a; Wautier et al., 2002; Kassam et al., de®ning it in the precise language of mathemat- 2003a) including evidence of convergence of ics; and the one method tends to follow the other these elements between lakes (RuÈber and Ad- in strict scienti®c order and historical continui- ams, 2001; Kassam et al., 2003b); however, those ty.''±D'Arcy Thompson, 1917 (On Growth studies dealt only with patterns of morphologi- and Form) cal diversity rather than with its magnitude. -
Doctoral Thesis
Doctoral Thesis Studies on mouth brooding cichlids of Lake Malawi: genetic, ecological and morphological differences (Summary) Shaharior Hashem Department of Bioresource Science Graduate School of Biosphere Science Hiroshima University March 2020 Summary of the Dissertation In most recent couple of decades, East African cichlids have been studied as a classic example of fast vertebrate evolution and biological diversification. A big number of cichlid species have been identified from three great lakes of East Africa: Lakes Malawi, Tanganyika, and Victoria. Malawian haplochromine cichlids are endemic, suggesting that most of this diversification has taken place within the temporal and spatial boundaries set by the lake shores. Examination of the genetic structure of recently divergent populations or species is relevant to our understanding of the process of speciation in general. Species richness and their divergence in morphology and trophic adaptations make cichlids premier of rapid speciation. Hybridization between species or genera is considered to have rapidly boosted genetic variation, which may enable speciation and adaptive radiation. Haplochromines are divided into 2 large groups. One is called ‘mbuna’, living on rocky shores and feeding mainly on attached algae, and another is ‘non-mbuna’, living in sandy shores or the ‘pelagic zone’ and feeding on a variety of items. Cichlid fishes have evolved incredible morphological and behavioral diversity. Within Lake Malawi, the phenomena of hybridization and retention of ancestral polymorphism explain allele sharing across species. Egg-spots, particularly on male fins, are considered to have a vital role in the courtship and spawning behavior of haplochromines. These spots contain a transparent outer ring and a bright colored yellow, orange or reddish center. -

Therefore, he is known as the ‘father of modern taxonomy’. In his attempt to describe the entire natural world he gave all known species (mineral, plant, animal) a two-part name, also called binomial nomenclature. Hereby he established conventions for the naming of living organisms that became universally accepted in the scientific world. Binomial nomenclature: The scientific naming of species whereby each species receives a Latin or Latinized name of two parts, the first being the genus and the second being the specific epithet. The genus name is always a noun, italicized (or underlined) and capitalized; the species name is a descriptive term, italicized (or underlined) and not capitalized.
