通过理论模型研究了性选择和生态多样性驱动的同域物种形成的可能性。特别是我们专注于岩石居住haplochromine慈鲷物种在维多利亚湖。这些慈鲷科鱼类的高物种形成率被解释为它们明显的能力，迅速专门化到一个大的多样性的喂养生态位。然而，Seehausen及其同事证明了性选择在维持物种之间生殖障碍方面的重要性。我们的个人为导向的模型集成了生态位分化和费舍尔失控的过程，这是有限的可见性的限制。该模型表明，快速同域物种形成或物种灭绝，这取决于性选择的强度。
A theoretical model is studied to investigate the possibility of sympatric speciation driven by sexual selection and ecological diversification. In particular we focus on the rock–dwelling haplochromine cichlid species in Lake Victoria. The high speciation rate in these cichlids has been explained by their apparent ability to specialize rapidly to a large diversity of feeding niches. Seehausen and colleagues however, demonstrated the importance of sexual selection in maintaining reproductive barriers between species. Our individual–orientated model integrates both niche differentiation and a Fisherian runaway process, which is limited by visibility constraints. The model shows rapid sympatric speciation or extinction of species, depending on the strength of sexual selection.
