The genus Akodon Meyen, is one of the most species-rich among sigmodontine rodents and has great chromosome variability. However, it may help control insect pest populations throughout its native range. The effect of habitat fragmentation and species diversity loss on hantavirus prevalence in Panama.

Analyses of individual-level characteristics.

In our sample two females presented heteromorphic sex chromosomes XY. Cricetidae in Santa Catarina State, Brazil. These included the total accumulated rainfall of the current month, most recent 2 months including montendis monthmost recent 3 months, most recent 6 months, most recent 12 months, and of the same 4-month precipitation season T, D, or W of the previous year.

No information on birth mass is available, but average birth mass of other members of Akodon e. Analyses of serostatus for hantaviral antibodies. A habitat-based model for the spread of hantavirus between reservoir and spillover species.

Experimental infection with Puumala virus, the etiologic agent of nephropathia epidemica, in bank voles Clethrionomys glareolus. Because significant interaction was found between the effects of sex and serostatus on longevity in several of these tests, additional one-way ANOVAs of the effect of serostatus on longevity were run for each sex separately for each of the above comparisons. Received Aug 31; Accepted Nov 5. View large Download slide. In this work we found the same variability described in Brazil, which involve the presence of a B chromosome, X chromosomes variants and seeming XY females.

Montensie represent observable behavioral effects of Hantavirus infection in a natural host, all of which are modifications that would facilitate horizontal transmission of the virus.

Thus, this report provides comparative data on populational and other characteristics of the species near its distributional limit. Analyses of each season separately showed an interaction between the effects of serostatus and sex on longevity in the dry and wet seasons.

The ecology and evolutionary history of an emergent disease: Akodon montensis is solitary, with most intraspecific interactions occurring during mating season.
