“…tant. Furthermore, genetic data (Rodriguez-Romero et al, 1975;Uribe et al, 1974) does not support differentiating the nominal taxa. Therefore, we have chosen to recognize Peromyscus alstoni as a monotypic species.…”

“…Davis (1944) and Davis and Follansbee (1945) synonymized orizabae 2ind perotensis with alstoni, and recognized two geographic races, N. a. alstoni and N. a. perotensis (included orizabae). Subsequent investigators (Burt, 1960;Hooper, 1959;Klinginer, 1968;Rodriguez-Romero et al, 1975;Uribe et al, 1974) have supported the close relationship of Neotomodon and Peromyscus. Yates et al (1979) synonymized the two genera under Peromyscus-X\ms at the time of this study the nomenclature of the volcano mouse consisted of Peromyscus alstoni alstoni and Peromyscus alstoni perotensis.…”

The volcano mouse, Peromyscus (Neotomodon) alstoni, occurs at high elevations in the trans volcanic belt of Mexico. Recent fieldwork in the state of Tlaxcala resulted in large series of P. alstoni from populations located between the two recognized subspecies {P. a. alstoni and P. a. perotensis). Morphometrical analyses were conducted to test the value of described subspecific characters as well as redefine the boundary of the subspecies. Univariate and multivariate analyses were used to determine age, secondary sexual, individual, and geographic variation. Significant differences were found among four age classes. There were no significant differences in secondary sexual variation. Analysis of geographical variation failed to differentiate samples of P. alstoni, thus indicating that the species is monotypic.

“…Adults usually weigh from 40 to 50 g ( 19 ). A cytogenetic analysis shows that its chromosome number is 2n = 48 with a fundamental number NF = 66, like Peromyscus ( 20 ). Neotomodon alstoni is listed as Least Concern species, according to the red list of the International Union for Conservation of Nature (IUCN) ( 21 ).…”

The mouse N. alstoni spontaneously develops the condition of obesity in captivity when fed regular chow. We aim to study the differences in metabolic performance and thermoregulation between adult lean and obese male mice. The experimental approach included indirect calorimetry using metabolic cages for VO2 intake and VCO2 production. In contrast, the body temperature was measured and analyzed using intraperitoneal data loggers. It was correlated with the relative presence of UCP1 protein and its gene expression from interscapular adipose tissue (iBAT). We also explored in this tissue the relative presence of Tyrosine Hydroxylase (TH) protein, the rate-limiting enzyme for catecholamine biosynthesis present in iBAT. Results indicate that obese mice show a daily rhythm persists in estimated parameters but with differences in amplitude and profile. Obese mice presented lower body temperature, and a low caloric expenditure, together with lower VO2 intake and VCO2 than lean mice. Also, obese mice present a reduced thermoregulatory response after a cold pulse. Results are correlated with a low relative presence of TH and UCP1 protein. However, qPCR analysis of Ucp1 presents an increase in gene expression in iBAT. Histology showed a reduced amount of brown adipocytes in BAT. The aforementioned indicates that the daily rhythm in aerobic metabolism, thermoregulation, and body temperature control have reduced amplitude in obese mice Neotomodon alstoni.
