Akodon montensis is an abundant species distributed in Argentina, Brazil and Paraguay, and has a great chromosomal variability (Kasahara. J Parasitol. Apr;83(2) Besnoitia sp. (Protozoa:Toxoplasmatinae) from Akodon montensis (Rodentia:Cricetidae) in Santa Catarina State, Brazil. Range Description. This species occurs from east Paraguay (Gamarra de Fox and Martin, ), northeast Argentina (Pardias et al., ), and southeast Brazil.

Even though, in Akodon montensis this condition has a relative low frequency Fagundes et al. Five specimens four females and one male had 25 chromosomes in all analyzed cells due to the presence of a small submetacentric B chromosome Fig. Discussion The studied populations of Akodon montensis from Brazil showed high chromosome variability Kasahara and Yonenaga-Yassuda ; Fagundes et al. Animals with bilateral symmetry akidon dorsal and ventral sides, as well as anterior and posterior ends.
On the basis of the year climatic mean for precipitation in the RNBM area, we defined 3 precipitation seasons Fig.

Therefore, we undertook this study to investigate some of the factors that may affect both population and individual characteristics, and hantavirus occurrence and prevalence levels, within A. To our knowledge, our study is the first to report both a lack of consistent seasonal variation together with a strong seasonal interaction with habitat in seroprevalence levels. Classification Kingdom Animalia animals Animalia: Our results of DAPI staining showed high homology among karyotypes of specimens from Argentina and those for Brazil studied with G-banding method Kaodon and Yonenaga-Yassuda ; Silva and Yonenaga-Yassudawhich indicates a high conservation in the standard karyotype of this abundant and widely distributed species.
Viability of the critically endangered African wild ass Equus africanus population on Messir Plateau Eritrea. In North America outbreaks of hantavirus pulmonary syndrome HPS have been correlated with precipitation patterns Eisen et al. No phenotypic malformations were detected in both cases.
ADW: Akodon montensis: INFORMATION
Click montesis to view. In our study seroprevalence levels differed by locale and this difference varied seasonally. From eighteen females, nine This conversion is primarily of forested land to agriculture crop or pastureinterspersed by smaller forest remnants Koch et al.
Longevity differed significantly according to serostatus in montejsis in 2 locales R3B, JJB and in both years. No information on birth mass is available, but average birth mass of other members of Akodon e. Microhabitat selection of five sigmodontine rodents in a forest—steppe transition zone in northwestern Patagonia.
However, additional data are needed to understand the dynamic of the multiple chromosome polymorphism observed in this species of sigmodontine rodents. Akodon montensis montane akodont Facebook.
We used the Huggins closed-capture model, allowing variable capture probabilities among sampling events trapping nights and constraining the probability of capture and recapture to be equal.
Received Aug 31; Accepted Nov 5. Means within the same row followed by different letters have significantly different means of ranked values. The sigmodontine rodent genus Akodon is a large, diverse, and geographically widespread group distributed throughout South America from Colombia to southern Argentina and Chile Musser and Carleton Climate variability and change in the United States: Although most studies have failed to reveal effects on the host of hantaviral infection of such variables as respiratory akoddon O’Connor et al.
In these instances, the minimum number known alive MNKA was used as the population estimate. Movement distances of five rodent and two marsupial species in forest fragments of the coastal Atlantic rainforest, Montsnsis.
Accessed April 18, at http: Similar to other small mammals, A. Feeding of small rodents on seeds and fruits: Bozinovic, ; Goncalves, et al. Couto and Talamoni, ; Couto and Talamoni, ; Jordao, et al. Myths and facts on ratadas: High seroprevalence of hantavirus infection on the Azuero Peninsula of Panama. Analyses of individual-level characteristics. Geographic Range Akodon montensis is found in the northeastern portion of Argentina, along the southeastern coast of Brazil, and throughout eastern Paraguay.
Analyses were conducted of all individuals, and of males only, to determine whether seropositive and seronegative animals showed differences in the displacement of their home-range centroids from the previous sampling session.

Reproductively active and fertile females can be found in the wild with XY chromosomes. Within these habitats it occupies evergreen, semi-deciduous, and riparian gallery forests. Finally, in the present paper we report for the first time a trisomy of chromosome 11 in a single individual.
