PROF. C. KOSSWIG has suggested1 that factors which may contribute to the high evolutionary response of Cichlid fishes to the environments of the Great African Lakes are selective mating and specialized breeding habits, including monogamy at least until one brood becomes independent. A beginning has been made in the study of a group of closely related species in Lake Nyasa, the Tilapia of the T. squamipinnis group2,3. Before 1939 these had been considered as a single species. Slight differences… 
The mbuna cichlids of Lake Malawi: a model for rapid speciation and adaptive radiation
TLDR
There is no good evidence for monophyly in the mbuna, rather mitochondrial DNA phylogenies indicate that they are polyphlyetic with respect to benthic feeding cichlids of the genera Aulonocara, Alticorpus and some species of Lethrinops, and sexual selection acting on male colour seems the most plausible mechanism for initial species divergence.
Diversification In African Cichlid Fishes: From Speciation To Macroevolutionary Patterns
TLDR
This result suggests that ecological and behavioral traits have a strong influence on the scale and degree of population subdivision, a finding which has potentially important implications for understanding differential propensities for diversification among lineages and phylogenetic patterns of diversity.
ECOLOGICAL FACTORS IN SPECIATION
TLDR
It is more important to determine the respective roles of geographical and ecological factors in speciation, and to find out whether they operate consecutively or concomitantly, than to consider the role of sympatric speciation.
THE ROLE OF SEXUAL SELECTION AS AN ISOLATING MECHANISM IN THREE SPECIES OF POECILIID FISHES
TLDR
The present report is concerned with a single aspect of a study now in progress of the ecological relations within a mixture of three sympatric species of PoeciIiid fishes which show an extraordinary degree of habitat coincidence in certain of the fresh waters of Trinidad.
Ecological Factors I N Speciation
The past decades have seen the gradual formulation of the theory of geographical speciation, principally based 011 work in the fields of the systematics of mammals, birds, insects, and mollusks. This
DIVERGENCE WITH GENE FLOW IN THE ROCK‐DWELLING CICHLIDS OF LAKE MALAWI
TLDR
The effect of recent lake‐level fluctuations on patterns of allelic diversity in the genus Metriaclima is determined, to describe the patterns of population structure within this genus, and to identify barriers to migration.
Population structure and colour variation of the cichlid fishes Labeotropheus fuelleborni Ahl along a recently formed archipelago of rocky habitat patches in southern Lake Malawi
TLDR
Relative to shoreline populations, reduced levels of gene flow among populations inhabiting isolated, deep–water islands provides greater opportunities for drift, adaptation to local conditions, or sexual selection to effect genetic differentiation in this species.

TLDR
It is suggested that ecological and behavioral traits have a strong influence on the scale and degree of population subdivision, a finding that has potentially important implications for understanding differential propensities for diversification among lineages and phylogenetic patterns of diversity.
Ways of Speciation in Fishes
TLDR
The isolated form, as a byproduct of genic differentiation, the isolated form will finally develop characters by which fertility with the original species becomes impossible; speciation is the result of a prolonged geographic isolation.
Patterns of Speciation in Marine Gastropods: A Review of the Phylogenetic Evidence for Localized Radiations in the Sea*
TLDR
P phylogenetic evidence from diverse marine gastropods is reviewed to test Mayr's prediction that recently diverged sister species should not be sympatric over most of their ranges, suggesting that classical models of allopatric divergence are insufficient to explain marine speciation.
