The University of Chicago Press. As in most previous studies of rodent-hantavirus systems, seroprevalence varied among sampling locales and was higher among males. Endothermy is a synapomorphy of the Mammalia, although it may have arisen in a now extinct synapsid ancestor; the fossil record does not distinguish these possibilities. Though we edit our accounts for accuracy, we cannot guarantee all information in those accounts.

These results indicate the importance of vegetational structure Goodin et al.

Additionally, the subtelocentric X chromosome presented a large positive C-band, which covered its akoddon arm Fig. Secondly, some members of the genus Akodon have a significant impact on agriculture by foraging on crops e. These locales were chosen to represent a cross-section of potential micro-habitat types representing a continuum of human disturbance.

Finally, in the present paper we report for the first time a trisomy of chromosome 11 in a single individual. Sherman Traps, Tallahassee, Florida placed on the ground, and another placed zkodon branches or vines 2—3 m above ground, to sample species that are primarily arboreal.

Management of the area as a biosphere reserve provides some relative control to compare areas surrounding the Reserve that are undergoing rapid land-cover conversion.

Abstract The genus Akodon Meyen, is one of the most species-rich among sigmodontine rodents and has great chromosome variability. Cricetidae in Santa Catarina State, Brazil.

ADW: Akodon montensis: INFORMATION

Two-way ANOVAs were conducted to assess the relationship between longevity and the serostatus and sex of individuals for all data combined, and for each season, locale, and year separately. Additionally, two-way ANOVAs were conducted to evaluate interaction effects between serostatus and other variables, and between sex and other variables. Results All individuals of Akodon montensis had an autosome complement composed of nine pairs of aodon to medium size metacentric chromosomes, and two small-sized pairs, one acrocentric and one metacentric.

Effects of the virus on host individuals and populations are poorly understood.

Chromosome pairs with positive signals after silver staining. For the first capture, an animal was assessed to have been alive for a minimum of 1 month if it was a juvenile, 2 months if subadult, and 3 months if adult. For captures in subsequent sessions the number of months between sessions was added to the age estimated at 1st capture.
