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.

Although most studies have failed to reveal effects on the host of hantaviral infection mpntensis such variables as respiratory function O’Connor et al. However, in most mammals care of the young e.

Higdon, ; Higdon, Geographic Range Akodon montensis is found in the northeastern portion of Argentina, along the southeastern coast of Brazil, and throughout eastern Montensiis.

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.

Connect with us Help us improve the site by taking our survey. 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. Annual Review of Ecology and Systematics We thank to Marcelo Cavicchia and to several members of the LGE for the cooperation in the fieldwork.


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 secret life of possums: Ecological disturbances, especially those of anthropogenic origin, might play a role in the emergence of hantaviruses as akoxon pathogens Mills ; Ruedas et al. The ecology and evolutionary history of an emergent disease: Akodon montensis is solitary, with most intraspecific interactions occurring during mating season.

Akodon montensis is an abundant species distributed in Argentina, Brazil and Monteneis, and has monteniss great chromosomal variability Kasahara and Yonenaga-Yassuda ; Musser and Carleton As demonstrated by our study, of particular importance will be mathematical models that explicitly incorporate spatial and habitat variability and are capable of investigating these phenomena at multiple spatial scales Goodin et al.

The likelihood of detecting hantaviral antibodies in hosts has been correlated with rodent density, biodiversity, topography, and vegetation at a macroscopic scale Biggs et al.
