“…Unlike that observed by Mikesic and Drickamer (1992) in Mus musculus domesticus and that suggested by Brown (1953), we did not find any differences in home range size between adult and juvenile individuals of A. azarae. This could be due to the fact that in our study, animals which established home ranges were reproductively active, in spite of being classified as juveniles by their weights.…”

. 1999. Factors affecting home range size and overlap in Akodon azarae (Muridae: Sigmodontinae) in natural pasture of Argentina. Acta Theriologica 44: 37-44.Differences in home range size in relation to sex, age, breeding and non-breeding periods were studied. Home range size and overlap were examined at different densities values in populations of Akodon azarae (Fischer, 1829) on railway banks in southern Córdoba Province (Argentina). The sampling was carried out between October 1994, and February 1997, using the capture-mark-recapture method. Home range size in A. azarae was determined by sex and breeding period, and it was independent of the observed density values. Home range size of males was always larger than that of females. Increase of population density during the breeding period affected the degree of intersexual overlap of home range.

“…For instance, mice in standard laboratory enclosures (48 X 26 cm) had decreased levels of neurogenesis compared with mice in larger enclosures (86 X 76 cm; for a review, see Van Praag, Kempermann, & Gage, 2000). This represents an increase in spatial-area use of 5 X the standard cage enclosures, but even this increase in spatial area is far below their natural home range of -300 m^ (Mikesic & Drickamer, 1992). Our increase in spatial area was 25 X the standard cage enclosure, thus we assumed that an increase of this magnitude would be sufficient to induce changes in cortical attributes.…”

Differences in an animal's spatial environment can have dramatic effects on the hippocampus, an area of the brain involved with spatial processing. Animals in spatially impoverished environments have decreased hippocampal attributes. However, we do not know if differences in the spatial environment differentially interact with territorial status, which also covaries with hippocampal attributes. Here, we asked whether territoriality and differential spatial-area use interact to generate different effects on cortical attributes (reptilian hippocampal homologue) in lizards. We compared medial and dorsal cortical attributes between territorial and nonterritorial morphotypes of side-blotched lizards, Uta stansburiana, in larger versus smaller (i.e., spatially impoverished) enclosures. We found that territorial males had increased neurogenesis rates in their medial cortices in larger enclosures when compared with their siblings in smaller enclosures; nonterritorial males had low levels of neurogenesis regardless of enclosure size. Enclosure size had no significant effect on cortical volumes or the total number of neurons in either cortical region. These results suggest that territorial morphotypes may be more sensitive to changes in the spatial environment, thus leading to increases in regulation of neurogenesis in the face of increased spatial processing and physical activity demands.

“…A study conducted by Mikesic & Drickamer (1992) demonstrated that the home-range size of mice (M. musculus) varies significantly between the sexes and increases with age. Home-range sizes of juveniles of the two sexes are nearly equal, but males increase home-range area after maturity.…”

The occurrence of the larval cestode Cysticercus fasciolaris in rodent populations from the Cuxtal ecological reserve, Yucatan, Mexico

Cysticercus fasciolaris is the larval stage of the cestode Taenia taeniaeformis, whose definitive hosts are mainly cats. This larval stage uses a wide variety of small rodents, and occasionally birds and humans, as intermediate hosts. In the Yucatan, there are no reports of the presence of this cestode in animal populations. The aim of this study was to evaluate the occurrence of C. fasciolaris in rodent populations from the Cuxtal ecological reserve, Yucatan, Mexico. Trapping of rodents was conducted from October 2009 to April 2010 in 40 households in Molas, in which Sherman traps were placed both inside and outside backyards. Rodents were dissected to inspect the liver for the presence of the worm. To determine risk factors associated with infection, univariate analysis was performed using sex, age, species, trapping site, and season as independent variables. Variables with a P value < 0.2 were analysed using a logistic regression model. In this study, 411 individuals of six rodent species were trapped; Mus musculus was the most abundant (78%), followed by Rattus rattus (13%) and the wild species Peromyscus yucatanicus, Ototylomys phyllotis, Heteromys gaumeri and Reithrodontomys gracilis (9%). Only 7.5% (n = 31) of M. musculus and R. rattus were infected with C. fasciolaris (demonstrated by the presence of liver cysts) with a prevalence of 9.0% and 3.5%, respectively. Both adults and male mice were 4.33 and 3.46 (OR values) times more likely to have C. fasciolaris than juveniles and females respectively. We can conclude that in the Cuxtal Reserve, Yucatan, Mexico, the prevalence of C. fasciolaris is higher in M. musculus, and that adult males had a higher probability of infection. Wild species, mainly P. yucatanicus, were not found to be infected with the cestode, but its presence in the backyards of households could result in a potential risk of acquiring this infection.
