[Cranial features and feeding types of subspecies forms of Moschus moschiferus L. (Moschidae, Cetartiodactyla)].

The relationship between the cranial features and feeding types in the musk deer has been studied. According to the results of dispersion and cluster analyses, the six modern subspecies were divided into four trophic (mixed-feeders) subcategories--by the ratio of grass and leaves with a significant fraction of lichens (from 25 to 75%) in their diet. It was established that some morphological features of the skulls of subspecies forms correlate with their feeding specialization and habitat and can thus be useful in the reconstruction of adaptations of extinct Moschidae taxa.

[Results of mandibular bone plastic repair with vascularized autotransplants].

A total of 96 vascularized flaps used in the reconstruction of the mandible in 91 patients are analyzed. In 82 cases the defects appeared after treatment of malignant and benign lesions of the mandible. In 18 patients the mandible was reconstructed using rib grafts.

[Molecular genetic diversity of musk deer Moschus moschiferus L., 1758 (Ruminantia, Artiodactyla) from the northern subspecies group].

Genetic diversity within the northern subspecies group of musk deer Moschus moschiferus L, 1758 was examined based on the mtDNA control region hypervariable fragment (300-bp) sequence polymorphism. Nucleotide diversity, constituting 2.6% for the whole sample (n = 34), varied in the range from 0.

[Taxonomy of the musk deer (Artiodactyla, Mammalia)].

We studied the chromosome sets and specific morphological features and phenetic traits of hair cover coloration, as well the pattern of its inheritance upon experimental hybridization. The diploid set of chromosomes in the animals from the northern part of the range contains 2n = 58 (there are two additional B-chromosomes in the Far Eastern musk deer) and is identical to that from the southern musk deer forms. Discrete polymorphic features of neck and hair cover coloration have been identified in the northern and southern musk deer, and these are used as taxonomic features.
