Abstract EN
Fishes of the family Cichlidae are famous for their spectacular species flocks and therefore constitute a model system for the study of the pathways of adaptive radiation.
Their radiation is connected to trophic specialization, manifested in dentition, head morphology, and body shape.
Geometric morphometric methods have been established as efficient tools to quantify such differences in overall body shape or in particular morphological structures and meanwhile found wide application in evolutionary biology.
As a common feature, these approaches define and analyze coordinates of anatomical landmarks, rather than traditional counts or measurements.
Geometric morphometric methods have several merits compared to traditional morphometrics, particularly for the distinction and analysis of closely related entities.
Cichlid evolutionary research benefits from the efficiency of data acquisition, the manifold opportunities of analyses, and the potential to visualize shape changes of those landmark-based methods.
This paper briefly introduces to the concepts and methods of geometric morphometrics and presents a selection of publications where those techniques have been successfully applied to various aspects of cichlid fish diversification.
