“…This is due primarily to the superior methods of chromosome harvest available in these species (e.g., Lee and Elder 1980). Collectively , the vertebrate data have shown that variation in both heterochromatin amount and chromosomal position is or can be extensive both within and across phyletic groups (Arnason 1974, Yosida 1975, Mascarello and Mazrimas 1977, Pathak and Wurster-Hill 1977, Schmid 1978a, b, Mengden 1981, Haiduk et al 1981, Baverstock et al 1982, Patton and Sherwood 1982. Most species invariably possess C-bands at or around the centromeres (pro centric), and frequently at the chromosome tips (telomeric).…”

“…However, C-banding studies have demonstrated the presence of pericentromeric heterochromatic regions in most karyotypes of bat species analysed to date, with similar size to those described in most of the mammal species (Pathak et al, 1973;Bickham, 1979;Haiduk et al, 1981;Morielle-Versute et al, 1996;Santos and Souza, 1998;Volleth et al, 1999;Volleth et al, 2001).…”

“…It has been suggested that the difference in the nuclear content of bats in relation to other mammalian groups is mainly because of their lack of repetitive DNA sequences (Van Den Bussche et al, 1995). However, C-band studies in bat chromosomes have revealed several species with large amounts of heterochromatic regions (Haiduk et al, 1981;MorielleVersute et al, 1996;Volleth et al, 2001).…”

This paper reports the molecular and cytogenetic characterization of a HindIII family of satellite DNA in the bat species Pipistrellus pipistrellus. This satellite is organized in tandem repeats of 418 bp monomer units, and represents approximately 3% of the whole genome. The consensus sequence from five cloned monomer units has an A-T content of 62.20%. We have found differences in the ladder pattern of bands between two populations of the same species. These differences are probably because of the absence of the target sites for the HindIII enzyme in most monomer units of one population, but not in the other. Fluorescent in situ hybridization (FISH) localized the satellite DNA in the pericentromeric regions of all autosomes and the X chromosome, but it was absent from the Y chromosome. Digestion of genomic DNAs with HpaII and its isoschizomer MspI demonstrated that these repetitive DNA sequences are not methylated. Other bat species were tested for the presence of this repetitive DNA. It was absent in five Vespertilionidae and one Rhinolophidae species, indicating that it could be a species/genus specific, repetitive DNA family.

“…Multiple inversions in chromosome 6 have been noted in Peromyscus (Bobbins and Baker, 1981;Rogers, 1983). With the resolution of Gbands available to us it is impossible to distinguish the inversion in chromosome 6 in Reithrodontomys from that found in some species of Peromyscus.…”

“…In this example, data on differentially-stained chromosomes have provided a magnitude of information that could not have been afforded by standard karyotypic preparations. Banding studies of pteropodid and phyllostomid bats (Patton and Baker, 1978;Baker and Bickham, 1980;Haiduk et al, 1981;Haiduk and Baker, 1982) and oryzomyine rodents (Baker et al, 1983) are additional examples that suggest caution in interpreting chromosomal evolution based on standard chromosomal morphology.…”

ABSTRACT.-G-and C-banded karyotypes of Reithrodontomys raviventris were examined to identify the amount and types of chromosomal change that have occurred in this species. The evolutionary origin and phylogenetic relationships of R. raviventris were evaluated by comparing G-and C-band data with six additional species of Reithrodontomys (fulvescens, creper, mexicanus, megalotis, montanus, and sumichrasti). Banding homologies indicate that the low diploid number forms (raviventris, montanus, megalotis, and sumichrasti) shared a common ancestry and that a major dichotomy exists among these taxa. R. raviventris and R. montanus share a phylogenetic relationship as indicated by 10 shared-derived chromosomal rearrangement events. R. megalotis and R. sumichrasti represent a second well-defined clade. These chromosomal banding data suggest an alternative hypothesis to the traditionally accepted view that R. raviventris is most closely related to R. megalotis.The salt-marsh harvest mouse, Reithrodontomys raviventris, is an endangered species restricted to salt marshes in the San Francisco Bay area. Two subspecies, R. r. raviventris (Dixon, 1908) and R. r. hahcoetes (Dixon, 1909) are recognized, representing southern and northern populations, respectively (Fig. 1). Previous studies have concluded that R. raviventris and another locally abundant harvest mouse, R. megalotis longicaudus, were derived from a common ancestral stock with R. megalotis being the closest living relative of R. raviventris. Hooper's (1944) assessment of San Francisco Bay as an isolating mechanism for speciation of small mammals first introduced the notion of a phylogenetic relationship between R. raviventris and megalotis. Fisler (1965) pursued the idea that R. raviventris was a megalotis derivative in a detailed study of adaptation and speciation of harvest mice in the San Francisco Bay area.Chromosomal studies were undertaken by Shellhammer (1967Shellhammer ( , 1969 to document variability in the three forms of harvest mice from San Francisco Bay. Both subspecies of R. raviventris possess a 2n = 38, FN = 72 karyotype, but vary in chromosomal morphology. The standard karyotype of R. megalotis longicaudus is similar (2n = 42, FN = 80), which led Shellhammer (1967) to propose that the karyotype of R. raviventris had most likely evolved from one like that found in R. megalotis.Recent studies of chromosomal evolution within and among species of Reithrodontomys document that the genus is characterized by a high amount of chromosomal variability (Carleton and Myers, 1979; Robbins and Baker, 1980;Engstrom et al., 1981). On the basis of standard karyotypic data, there appear to be two major groups. One group includes species with high diploid numbers (50-52) and mostly acrocentric elements (Reithrodontomys fulvescens, mexicanus, creper, gracilis, tenuirostris, and humulis). The second assemblage includes species characterized by low diploid number (38-42) and an entirely biarmed karyotype (R. raviventris, montanus, megalotis, and sumichrasti). Carleton and ...
