1 MALAWI CICHLIDS SARAH ROBBINS BSCI462 SPRING 2013

2 CICHLIDS Family of fish within the infraclass Teleostei Over 1600 species discovered, Up to 3000 species predicted Most commonly found in Africa and South America Popular in freshwater aquariums, also used as a food source

3 AFRICAN RIFT LAKES Found in East Africa s Great Rift Valley 3 Lakes with Genetically distinct Lineages Lake Tanganyika, Lake Victoria, and Lake Malawi Lakes are less than 1 million years old (Smith et. al. 2003) Cichlid populations in the lakes are genetically divided on very small geographic scales (Streelman et. al.2004) Environmental stochasticity is common and may be a driving force behind speciation and hybridization in the lakes (Streelman et. al. 2004)

4 GENETIC CLUSTERS From Loh et. al. (2013)

5 EXPLOSIVE SPECIATION Ideal Model System for Rapid Adaptive Radiation More than 500 species each in Lake Victoria and Lake Malawi Occurred in 3 bursts Danley and Kocher (2001) Stages of Malawi Radiation

6 CONVERGENT EVOLUTION Convergent evolution between Lakes Malawi and Tanganyika shows that cichlids solve ecological problems in similar ways (Albertson 2006).

7 SEXUAL SELECTION Male-male competition: defense of a mating area Female choice of bright color patterns

8 SEXUAL SELECTION Male-male competition: defense of a mating area Female choice of bright color patterns

9 SEX REVERSAL Recruitment of novel sex chromosomes to maintain sexual color dimorphism Resolution of conflict between sex determination and maintenance of color pattern Example from Roberts (2009): OB Phenotype

10 SPECIATION IMPLICATIONS Novel Sex Determiners may lead to reproductive isolation From Roberts (2009)

11 HYBRIDIZATION Hybridization may explain high levels of genetic diversity within populations and an increased number of speciation events. Smith 2003: Hybridization between two geographically isolated populations led to an intermediate species in an area that was between the two populations.

12 CONSERVATION THREATS Overfishing presents a significant threat to maintenance of cichlid populations in the wild

13 FUTURE DIRECTIONS Comprehensive study of speciation mechanisms in cichlids Genetic basis of pigmentation variation Sex Reversal vs. Sexual Selection Conservation efforts to preserve species with rapid population loss from overfishing Stricter regulations on fishing Increased species awareness Male-biased conservation of highly colored species
