Comparing chromosomal and mitochondrial phylogenies of the Indriidae (Primates, Lemuriformes).

The Malagasy primate family Indriidae comprises three genera with up to 19 species. Cytogenetic and molecular phylogenies of the Indriidae have been performed with special attention to the genus Propithecus. Comparative R-banding and FISH with human paints were applied to karyotypes of representatives of all three genera and confirmed most of the earlier R-banding results.

Comparing chromosomal and mitochondrial phylogenies of sportive lemurs (Genus Lepilemur, Primates).

In recent years several new sportive lemur species (genus Lepilemur) have been described. In contrast to other lemur taxa, the genus shows comparatively high chromosomal variability, which, in addition to molecular data, can be used to infer phylogenetic relationships within the genus. By comparing R-banding patterns and fluorescence in-situ hybridization data, we detected chromosomal rearrangements that occurred during speciation within the genus.

Phylogenetic history of the Sifakas ( Propithecus: Lemuriformes) derived from cytogenetic studies.

The R-banded karyotypes of the different subspecies of Propithecus diadema and P. verreauxi are compared to each other and to that of P. tattersalli, as well as those previously reported of Indri indri and Avahi laniger.

Chromosomal evolution of the Hapalemur griseus subspecies (Malagasy Prosimian), including a new chromosomal polymorphic cytotype.

A cytogenetic study has been performed on Hapalemur griseus caught in different locations of the eastern and northern forests of Madagascar. This allowed the determination of the more precise distribution areas of the different subspecies and the isolation of a new cytogenetic polymorphic subspecies of H. griseus.
