    Summary It has been debated whether the extinct quagga was a distinct fourth species of African zebra or whether it was merely the southern variant of the Plains zebra (Equus burchelli). Using a radioimmunoassay (RIA) technique, we have shown that proteins remaining in quagga skins from museums are much more similar to serum proteins of the Plains zebra than to those of the other two extant zebras.

    Notes:
    Summary To investigate molecular evolution in a mammalian order with a comprehensive fossil record, we have constructedα-globin-like gene cluster maps for members of the order Perissodactyla. Although the arrangement of genes is the same in the five Equidae examined, the tapir and rhinoceros differ from each other and the horse in the position and number of their ζ genes, but not in the arrangement of theirα and θ genes. In contrast to morphological work, a dendrogram derived from restriction site maps associates the tapir with the horse rather than with the rhinoceros; however, this phylogeny is not statistically significant. Among the Equidae,Equus caballus emerges as an outgroup, in agreement with data from other disciplines.

    Abstract Chromosomal studies of Tibetan wild ass,Equus kiang holdereri are reported for the first time. A Robertsonian polymorphism resulting in diploid numbers of 2n=51 and 2n=52 was identified. This polymorphism involves the same elements that participate in the polymorphic Robertsonian rearrangement producing diploid numbers of 54–56 inE. hemionus kulan andE. hemionus onager. Comparison of mitochondrial DNA restriction fragment patterns among three unrelated kiang individuals and between kiangs and a Transcaspian kulan,E. hemionus kulan, indicates an approximately 1% nucleotide sequence divergence of mitochondrial DNAs between the two taxa. The chromosomal divergence betweenE. hemionus andE. kiang probably originated less than 500,000 years ago. Studies of additional Asiatic wild ass taxa are indicated in order to gain further insights into the speciation and systematics of this threatened group of mammals.

    Abstract The distribution of silver-stained nucleolus-organizing regions (NORs) in fibroblast chromosomes from all seven extant species of Equidae are described. There are variations in the number and locations of silver-stained NORs in different species but most of the cells in an individual of any speies had only 2 to 4 silver-stained NORs. In Equus przewalskii and E. caballus NORs were detected on up to three different chromosomes. In E. asinus 11 different chromosomes were observed to possess NOR sites. E. hemionus kulan and E. hemionus onager had NORs on 2 large metacentric pairs and a small acrocentric pair. In E. grevyi and E. burchelli NORs were located on 3 to 4 different pairs. E. zebra hartmannae had silver-staining over the telomere regions of the short arms of the chromosomes 1, 3 and 4. A comparison of G-banded chromosomes and silver-stained NORs has revealed one autosome with conserved G-band patterns and possessing a silver-staining NOR in all the species except E. asinus. Variations in the number and multichromosomal locations of NORs in various species could have evolved by pairing and exchanges between non-homologous chromosomal heterochromatin having similar satellite DNA sequences.

    Abstract The two subspecies of ruffed lemurs (Vareica variegata variegata andVarecia variegata rubra) have been maintained in captivity since 1959 and all institutions which hold ruffed lemurs have contributed data to theVarecia International Studbook. Studbook data were used to analyze inbreeding effects on survival in both subspecies ofVarecia. Several variables, including offspring's inbreeding coefficient, litter size, mother's inbreeding coefficient, and mother's age, were examined for significant associations with percent survivorship per litter. Percent survivorship per litter was negatively correlated to the offspring inbreeding coefficient in the black and white ruffed lemurs (p〈0.001) but no significant association was found for red ruffed lemurs. Although emphasis has been put towards the status of the red ruffed lemurs due to the small founder size, the black and white ruffed lemurs should also be managed with care due to the lower tolerance to inbreeding in captivity.
