“…This means, as suggested by Batzli and Henttonen (1993), that when home-range overlap is significantly lower than it would be expected by random distribution, individuals are avoiding one another. Steinmann et al (2005Steinmann et al ( , 2006a also found that during the breeding period, C. musculinus males' home ranges were twice as large as those of females and exhibited considerable overlap, with that of other males and of several breeding females. The greater home-range size and the intersexual overlap observed in males' home ranges might be a mechanism to increase the number of receptive females that they find to ensure optimal mating (Steinmann et al 2005(Steinmann et al , 2006a.…”

Sexual differences in home-range sizes and degree of overlap are considered a typical feature of rodent species with a promiscuous-polygynous mating system in which male spatial distribution is strongly influenced by search for mates and females are the territorial sex (Madison 1980;Gaulin and FitzGerald 1988;Heske and Ostfeld 1990).…”

“…In previous studies, Steinmann et al (2005Steinmann et al ( , 2006a found that during the breeding period, breeding females of Calomys musculinus keep exclusive, nonoverlapping home ranges that are spatially close. In these studies, female territoriality was assumed based on the exclusive use of space.…”

We studied territorial behaviour of Calomys musculinus, a promiscuous-polygynous species, in order to test the predictions that during the breeding period, homerange-owner females are more aggressive than home-range intruders and that males do not display territorial behaviour. At the core of the breeding season, we conducted 136 intrasexual and 66 intersexual encounters. The study was carried out in four 0.25-ha enclosures, each containing one independent population. We studied territorial behaviour utilising focal animal sampling to record behaviour. Encounters were conducted in a circular opaque arena (COA) near the home-range's activity mathematical centre (AMC). Amicable behaviour was not observed in any of the 78 trials among females. The rates of aggressive and submissive behaviour per female-female encounters varied in relation to whether they were home-range owners or intruders, the former being aggressive, the latter submissive. So we could link these drives to the territorial behaviour of C. musculinus. This result fits well with the already known territoriality of C. musculinus during the breeding season. In contrast, the 58 intrasexual male encounters did not show direct aggressive interactions between them. The rates of the different behaviours between males did not vary in relation to whether they were home-range owners or intruders. In our study, which took place during the breeding period, C. musculinus males were nonterritorial, and they never exhibited aggressiveness towards females.

“…As a result, the proportion of dispersing individuals in this period is large (e.g. Steinmann et al 2005). The probability of a dispersing individual to be exposed to a larger variety of parasites is likely high.…”

We investigated host and flea species composition across different habitats during dry and rainy seasons in the Western Usambara Mountains in Tanzania. During both seasons, similarity in flea species composition increased with an increase in the similarity in host species composition. Nevertheless, between-season within-habitat as well as within-season between-habitat similarity in host species composition was higher than similarity in flea species composition. Ordination of habitats according to their host and flea species composition demonstrated that the pattern of between-habitat similarity in both host and flea species composition varied seasonally. Despite the relatively rich mammal and flea fauna of the study region, the major contribution to variation in species composition between seasons and among habitats was due to a few species only. Flea assemblages on Lophuromys kilonzoi Verheyen et al., 2007 and Praomys delectorum Thomas, 1910 in different habitats were equally similar in either season. In contrast, flea assemblages on Mastomys natalensis (Smith, 1834) occurring in different habitats were more similar in the dry than in the rainy season, whereas the opposite was the case for fleas on Grammomys sp. In different hosts, the main differences in species composition of flea assemblages between seasons as well as among habitats were due to different flea species. Although our results support the earlier idea that parasite species composition is determined by both host species composition and habitat properties, the former appears to explain variance in flea species composition between localities in the tropics better than between localities in temperate and arid zones.

Under the hypothesis that the reproductive activity of a rodent species is influenced by conditions of the environment and by coexistent rodents, we assessed the relationship between environmental variables and reproductive activity of rodents at two spatial scales, field borders and trap sites, during the breeding period (spring, summer and autumn seasons) in pampean agroecosystems of Argentina. We distinguished between active and inactive sites, based on female reproductive condition. We conducted several statistical analyses to compare between active/inactive borders and trap sites for vegetation-rodent and rodent-rodent associations. The environmental variables useful for distinguishing active sites from inactive ones were different for each rodent species. Whereas vegetation cover, at the two habitat scales analyzed, seemed to be important for Akodon azarae , the crop types adjacent to borders seemed to be significant for Calomys musculinus to differentiate active/inactive sites. In the case of Calomys venustus , we could not identify one variable that reflected differences between border types. These associations would be related to the use that each rodent species makes of border and cropfield habitats, together with the resources they need at each moment of the breeding period.
