Lake Tanganyika's cichlid fishes represent one of the most diverse species assemblages of the world. In this study we focused on the tribe Tropheini which occupies several trophic niches, mostly in rocky habitats. We analysed morphological variation of seventeen closely related species by means of geometric morphometric methods and related these data to ecological characteristics and phylogeny of the study species. It turned out that morphology mostly correlated well with ecological parameters, but not always closely with the degree of the phylogenetic relatedness of the species. Overall, body shapes in the tribe Tropheini are of great evolutionary plasticity, but variation is restricted to particular body parts: the preorbital region once again emerged as a key factor that facilitated their impressive radiation.

形式、功能和系统发育:坦噶尼喀湖慈鲷部落 Tropheini 的比较形态测量学

坦噶尼喀湖的慈鲷鱼是世界上最多样化的物种组合之一。在这项研究中,我们专注于占据多个营养生态位的 Tropheini 部落,主要位于岩石栖息地。我们通过几何形态测量方法分析了 17 个密切相关物种的形态变异,并将这些数据与研究物种的生态特征和系统发育联系起来。结果表明,形态学主要与生态参数相关,但并不总是与物种的系统发育相关程度密切相关。总体而言,Tropheini 部落的身体形状具有很大的进化可塑性,但变异仅限于特定的身体部位:眶前区域再次成为促进其令人印象深刻的辐射的关键因素。
