The karyotype of Peromyscus grandis Rodentia: Cariotipo de Peromyscus grandis Rodentia: Swier 3John D.

Hanson 4Cibele G. Sotero-Caio 1and Robert D. BuildingLubbock, TX Peromyscus grandis is a rodent whose distribution is restricted to the mountain ranges of central Guatemala. This note represents carigrama first report of karyotypic data for this species. Cariogramma species of rodents are endemic to the highlands of Mesoamerica i. Although this region is considered one of the biodiversity hotspots for conservation priorities Myers et al.

Although most species within this group have been shown to exhibit extreme karyotypic conservation with few taxa varying in their sex chromosome composition Smith et al. Peromyscus grandis is the only species within the P.

Herein, the karyotype of P.

At least five metacentric spreads were examined and photographed per individual and the diploid 2n and fundamental numbers of autosomal arms FN were determined for each individual.

Karyograms were initially constructed by arranging bi-armed chromosomes based on cariogeama largest to smallest ; inferences of homology were then made using the chromosomal morphology depicted in the Committee for Standardization of Chromosomes of Peromyscus and Greenbaum et al.

Karyotypes were obtained from two individuals of P. Comparison to the standard karyotype for Peromyscus Committee for Standardization of Chromosomes of Peromyscus ; Greenbaum et al. The remaining autosomes are acrocentric see Fig. Although the chromosomal data depicted herein are based on standard carioograma non-differentially stainedmany inferences can be made relative to the G-banded datasets depicted in Greenbaum et al.

The karyotype of P. To further examine this apparent discrepancy, we examined the karyotypes of 17 individuals of P. The second difference observed in the karyotype of P. In general, the karyotype of P.
