Functional coupling constrains craniofacial diversification in Lake Tanganyika cichlids
Functional coupling, where a single morphological trait performs multiple functions, is a universal feature of organismal design. Theory suggests that functional coupling may constrain the rate of phenotypic evolution, yet empirical tests of this hypothesis are rare. In fish, the evolutionary transition from guarding the eggs on a sandy/rocky substrate (i.e. substrate guarding) to mouthbrooding...
متن کاملTempo and Mode of Diversification of Lake Tanganyika Cichlid Fishes
BACKGROUND Understanding the causes of disparities in species diversity across taxonomic groups and regions is a fundamental aim in evolutionary biology. Addressing these questions is difficult because of the need for densely sampled phylogenies and suitable empirical systems. METHODOLOGY/PRINCIPAL FINDINGS Here we investigate the cichlid fish radiation of Lake Tanganyika and show that per li...
متن کاملDepth and substratum differentiations among coexisting herbivorous cichlids in Lake Tanganyika
Cichlid fish in Lake Tanganyika represent a system of adaptive radiation in which eight ancestral lineages have diversified into hundreds of species through adaptation to various niches. However, Tanganyikan cichlids have been thought to be oversaturated, that is, the species number exceeds the number of niches and ecologically equivalent and competitively even species coexist. However, recent ...
متن کاملEvolutionary convergence of body shape and trophic morphology in cichlids from Lake Tanganyika
The cichlid species ̄ocks of the East African Great Lakes, Victoria, Malawi, and Tanganyika are unique examples of adaptive radiations (Greenwood, 1984). In each lake, highly specialized species that occupy a wide range of trophic niches are found, which are similar morphologically and behaviourally (Fryer & Iles, 1972). The similarities in trophic morphology between ®shes from different lakes c...
متن کاملHidden biodiversity in an ancient lake: phylogenetic congruence between Lake Tanganyika tropheine cichlids and their monogenean flatworm parasites
The stunning diversity of cichlid fishes has greatly enhanced our understanding of speciation and radiation. Little is known about the evolution of cichlid parasites. Parasites are abundant components of biodiversity, whose diversity typically exceeds that of their hosts. In the first comprehensive phylogenetic parasitological analysis of a vertebrate radiation, we study monogenean parasites in...
