Ancient lakes are excellent laboratories for evolutionary research, where species can be studied in the cradle where they originated. In this article, we investigate two endemic ostracod species flocks from the two oldest lakes in the world, Lake Baikal (LB) (ca. 28 myr) and Lake Tanganyika (LT) (ca. 12 myr), with DNA sequence data. Nuclear ITS1 failed to resolve the phylogeny of both flocks. Whilst most phylogenetic relationships of the Tanganyika flock are resolved with mitochondrial COI, the… Expand

Figures and Tables from this paper

Morphological and molecular diversity of Lake Baikal candonid ostracods, with description of a new genus
TLDR
An exceptional morphological diversity of Lake Baikal candonids is confirmed and it is shown that bothBaikal lineages are closely related to Candona, but only distantly to Pseudocandona. Expand
Cryptic diversity and speciation in endemic Cytherissa (Ostracoda, Crustacea) from Lake Baikal
TLDR
Current distribution data of Cytherissa species provide first indications for both geographic and ecological separation, and the first steps towards future, rigorous testing of focussed hypotheses on the causality of speciation through either allopatric isolation or parapatric ecological clines are provided. Expand
Phylogenetic position and age of Lake Baikal candonids (Crustacea, Ostracoda) inferred from multigene sequence analyzes and molecular dating
TLDR
Baikal candonid clades show a close phylogenetic relationship with Palearctic lineages, but their deep divergence is indicative of separate genera, and a monophyly of tribes that today live exclusively in subterranean waters is suggested. Expand
Conquest of the deep, old and cold: an exceptional limpet radiation in Lake Baikal
Lake Baikal is the deepest, oldest and most speciose ancient lake in the world. The lake is characterized by high levels of molluscan species richness and endemicity, including the limpet familyExpand
Quaternary ostracodes and molluscs from the Rukwa Basin (Tanzania) and their evolutionary and paleobiogeographic implications
Abstract Much of the spectacular biodiversity of the African Great Lakes is endemic to single lake basins so that the margins of these basins or their lakes coincide with biogeographic boundaries.Expand
Age and origin of Australian Bennelongia (Crustacea, Ostracoda)
TLDR
A much higher diversity in the genus Bennelongia (Ostracoda) in Western Australia than in eastern Australia is reported and mitochondrial COI sequence data is used for phylogenies, relative age estimates, lineage-through-time plots, and reconstructions of ancestral distributions to test four hypotheses that might explain the higher diversity. Expand
High cryptic diversity and persistent lineage segregation in endemic Romecytheridea (Crustacea, Ostracoda) from the ancient Lake Tanganyika (East Africa)
TLDR
It is found that ostracod populations from four different localities are genetically highly differentiated from each other when analyzing the mitochondrial 16S region, while they are almost identical with genetic markers from the nuclear genome (D1-D2 from the large ribosomal subunit (LSU) and ITS). Expand
A tale of time and depth: intralacustrine radiation in endemic Gammarus species flock from the ancient Lake Ohrid
TLDR
Phylogenetic analyses showed that endemic Gammarus species comprise an ancient species flock, withGammarus sketi from the feeder springs being their sister taxon outside the lake, and two novel mtDNA lineages were found within the lake. Expand
The endemic Cladophorales (Ulvophyceae) of ancient Lake Baikal represent a monophyletic group of very closely related but morphologically diverse species
TLDR
TheBaikal clade appears to represent a recent radiation, based on the low molecular divergence within the group, and it is hypothesized that the large morphological variation results from diversification in sympatry from a common ancestor in Lake Baikal. Expand
Detecting a signature of adaptive radiation : diversification in Lake Tanganyika catfishes
This thesis compares two independent radiations of catfish in Lake Tanganyika, Claroteine and Synodontis catfishes, to investigate generalities in patterns and processes of diversification betweenExpand

Speciation in ancient lake ostracods: comparative analysis of Baikalian Cytherissa and Tanganyikan Cyprideis
TLDR
Comparing phylogenies and estimated ages between the two ostracod flocks are compared and results are interpreted with regard to modern theories of evolution in ancient lakes, in particular, monophyly of endemic flocks and intra-lacustrine speciation. Expand
The Lake Tanganyika cichlid species assemblage: recent advances in molecular phylogenetics
TLDR
An account of the taxonomy and phylogeny of the Lake Tanganyika cichlid species assemblage, its relationship to the African cichLid fauna, key factors leading to the astonishing diversity and recently proposed alternative age estimates are presented. Expand
Ancient lakes as evolutionary reservoirs: evidence from the thalassoid gastropods of Lake Tanganyika
TLDR
It is shown here that there has been no acceleration in the rate of speciation in the thalassoid gastropods of the lake following lake colonization, suggesting limited within–lake speciation has occurred. Expand
The dynamics of endemic diversification: C01 phylogeny suggests explosive origin of the gastropods of Lake Tanganyika
TLDR
The first molecular phylogenetic treatment of 12 of the 18 endemic gastropod genera of Lake Tanganyika, based on a mitochondrial gene fragment of cytochrome oxidase I, finds a larger clade including Cleopatra, a thiarid genus widely distributed throughout East Africa, is monophyletic. Expand
Molecular and morphological evolution of the amphipod radiation of Lake Baikal.
TLDR
It is suggested that the amphipod fauna of Lake Baikal is polyphyletic; originating from two independent invasions of the lake. Expand
Phylogeny of the Lake Tanganyika cichlid species flock and its relationship to the Central and East African haplochromine cichlid fish faunas.
TLDR
These findings contradict the current hypothesis that ancestral riverine haplochromines colonized Lake Tanganyika to give rise to at least part of its spectacular endemic cichlid species assemblage and instead contradict the early phases of the Tanganyikan radiation, which affected Central and East African rivers and lakes. Expand
Endemic diversification of the monophyletic cottoid fish species flock in Lake Baikal explored with mtDNA sequencing.
TLDR
In the ancient Lake Baikal in East Siberia, cottoid fishes have diversified into an endemic flock of 33 species, and all but one of the current Baikalian genera formed well-supported monophyletic groups. Expand
Origin of the Superflock of Cichlid Fishes from Lake Victoria, East Africa
TLDR
A haplotype analysis shows that the most recent desiccation of Lake Victoria did not lead to a complete extinction of its endemic cichlid fauna and that the major lineage diversification took place about 100,000 years ago. Expand
The neglected side of speciation in ancient lakes: phylogeography of an inconspicuous mollusc taxon in lakes Ohrid and Prespa
TLDR
The patterns of speciation found in the genus Pisidium are compared to patterns in morphologically distinct molluscan groups in lakes Ohrid und Prespa and suggested scenarios of the endemic pea clam evolution within both lakes are suggested. Expand
Rapid evolution of an ancient lake species flock: Freshwater limpets (Gastropoda: Ancylidae) in the Balkan Lake Ohrid
TLDR
The study presents the first genetic confirmation for the existence of a species flock in a European ancient lake, and provides the first evidence for rapid morphological change in an European ancient Lake Ohrid species flock. Expand
