La formule chromosomique de quelques Insectivores indigènes

Karyotype and Chiasma Frequency in the Indian Hedgehog,Hemiechinus Auritus Collaris

“…The terminalization co-efficient at these stages has been calculated to be 0.76 and 0.94 res pecti vel y. The various members of the family Erinaceidae (Table II) are characterized by having a basic number of 48 chromosomes (PAINTER 1925;BovEY 1949a and1949b;SmssE 1956;GEISLER and GROPP 1967;KRAL 1967a and1967b;GROPP 1969 andSHARMA et al 197la and1971b). However, the fundamental arm number in the various species of hedgehogs varies from 90 to 96, which indicates that the basic number of 48 chromosomes, a characteristic feature for this family, seems to be superficial and requires sufficient cytological investigations for its final confirmation.…”

“…Excepting Erinaceus amurensis with 2n = 44 (KANG and KIM 1963 ), there occurs a common diploid number of 48 chromosomes in the various species of the genera Erinaceus and Hemiechinus of the family Erinaceidae, order Insectivora (PAINTER 1925;BovEY 1949a and1949b;SuiSSE 1956;JoRDON 1966;GEISLER and GROPP 1967;KRAL 1967a and1967b;BoRGAONKAR 1969;SHARMA et al 1971a and1971b). However, they depict certain taxonomical differences.…”

Cytological studies of certain desert mammals of Saudi Arabia 3. The karyotype of Paraechinus aethiopicus.

“…Except the hedgehog Erinaceus amurensis (2n=44) the diploid number of 48 chromosomes is seen in the various species of the well known genera, Erinaceus, Hemiechinus and Aethechinus (Painter 1925, Bovey 1949, Gropp and Geisler 1966, Gropp et al 1966, Jordon 1966, Geisler and Gropp 1967, Kral 1967, Hsu and Benirschke 1968, Borgaonkar 1969, Gropp et al 1969, Natarajan and Gropp 1971, Sharma et al 1971, Gropp and Natarajan 1972, Matthey 1973and Sharma et al 1975. To the best of our knowledge there is only one report about the karyotype fo Paraechinus aethiopicus from Iraq (Bhatnagar and El-Azawi 1978).…”

The chromosomes of a bat, <i>Pipistrellus tralatitus abramus</i>

“…

The extensive studies on the chromosomes of the Chiroptera made by Makino (1948) and Bovey (1949) have furnished valuable data toward understanding the evolutionary relation to the Insectivora which stands in close relationship to the Primates.Thanks to their work, the chromosome conditions of fourteen species of bats have been presented in sufficient detail, and the cytotaxonomical connection with the related orders has been discussed.The present author has made a study of the chromosomes of the Japanese house bat, Pipistrellus tralatitus abramus, a member of Vespertilionidae (Microchiroptera), by the application of an improved water-pretreatment squash technique which produced good chromosome slides available for the morphological analysis of chromosomes in a considerable detail. The results are presented in this paper.
