  journal={Animal Behaviour},
Mus domesticus usually exists commensally with humans, often reaching high densities in areas containing concentrated food resources. Mus spretus exists in vegetational habitats with generally scattered and seasonal food supplies. Two behavioural mechanisms could be responsible for determin- ing their spatial dispersion: (1) resident territory holders aggressively exclude intruders from attractive areas (aggressive exclusion hypothesis), or, (2) animals spread out to exploit scattered resources… Expand

Competitive behaviour in an island population of house mice,Mus domesticus
It is proposed that the lack of aggression among feral May mice may be due to the infeasibility of defending large territories, containing scattered resources, on an island where there is no real predation risk, and this hypothesis may explain the lower aggression and higher densities that are characteristic of populations of small mammals, reptiles and birds living on small islands.

Microhabitat and spatial dispersion of the grassland mouse (Mus spretus Lataste)
The hypothesis that mice may be able to maintain large exclusive ranges due to a combination of high predation pressure and a limited number of sites with sufficient ground and overhead cover is supported. Expand
Transgressive segregation in a behavioural trait? Explorative strategies in two house mouse subspecies and their hybrids
F1 males differed from both parental strains, with longer latencies to enter the arena, but explored the arena in a similar fashion as the M.?m.?domesticus males, thus displaying transgressive behavioural phenotypes, and add a new facet to the study of speciation. Expand
Effects of resource distribution on activity and territory defence in house mice, Mus domesticus
Abstract How much an animal invests in defending a territory depends, in part, on the quality, quantity and distribution of resources, but do animals target their investment in defence within theExpand
Social interaction alters attraction to competitor's odour in the mouse Mus spretus Lataste
A third experiment showed that the odour of an unfamiliar male was more attractive than that from an unfamiliar female, especially to males, and the consequences of these responses for maintaining spatial dispersion in this species are discussed. Expand
Influence of residency and social odors in interactions between competing native and alien rodents
Findings from both enclosure and field trials suggest that direct aggressive interactions between individual R. rattus and R. fuscipes probably facilitate segregation of space between these two species in wild populations, where resident animals may typically be the winners and exclude heterospecific intruders.

Aggression and Commensalism in House Mouse: a Comparative Study Across Europe and the Near East
Social behavior of house mice appears to be pliable rather than rigid and species specific, it can be changed rapidly according to ecological needs and such adaptability allows house mice to colonize various habitats. Expand
Structural complexity of territories: preference, use of space and defence in commensal house mice, Mus domesticus
The results suggest that mice prefer areas containing physical structure because this provides a degree of protection from predators but territories with complex physical structuring appear to be much more difficult to defend. Expand
Species-specific movement traits and specialization determine the spatial responses of small mammals towards roads
Abstract The barrier effect is a pervasive impact of road networks. For many small mammals individual avoidance responses can be the mechanism behind the barrier effect. However, little attention hasExpand
Interspecific competition in small rodents: from populations to individuals
Recent research approaches to interspecific competition in rodents are reviewed based on census data and species assemblages, that use regression analysis, time series analysis, removal and exclusion experiments, and showcase their own experimental research on the effects of inter specific competition on individual life-history traits in boreal voles.

Social organization in the aboriginal house mouse,Mus spretus Lataste: behavioural mechanisms underlying the spatial dispersion of competitors
Because rodents behave cryptically and often have large home ranges, the role of social defence in determining their spatial dispersion in grassland remains an enigma. Individual dispersion andExpand
Limiting Resources and Territoriality in Microtine Rodents
A set of hypotheses to predict under what conditions females and males should defend territories are proposed and the relation between diet and female territoriality holds up well, with the caution that diet and behavior are seldom analyzed in the same population at the same time. Expand
The Reproductive Ecology of the House Mouse

The reproductive biology of the house mouse seems uniquely suited to support ecological opportunism, and the relatively few environmental inhibitors of reproduction in this species should enhance the ability of dispersing young to colonize an exceptionally wide variety of habitats and climates.

Territoriality in Wild House Mice, Mus musculus L.
A number of workers have studied the social relationships that develop among caged groups of laboratory mice (reviewed by Scott and Fredericson, Physiol. Zool., 24:273–309, 1951). Brown (Ecol. Mono.,Expand
Eight 0.1-ha small-mammal enclosures were stocked with house mice on 6 June 1975 and mice were allowed to populate all grids until late December 1975, found to have similar assimilation efficiencies no matter where they were trapped in the grids. Expand

Interactions at the individual level, involving aggressive encounters and possibly other factors, form the basis of the interactions which have been demonstrated at the population level in the wild. Expand

The production and detection of odorous substances may contribute to the autonomy and relative reproductive isolation of some local populations of mice. Expand
Social and territorial behaviour of laboratory mice (Mus musculus L.) in small complex areas
H Hierarchically organized colonies of five male Mus musculus of strain LACA/CFW were transferred to complex arenas of 1·3, 2·6, 3·8 or 5·2 m 2; changes in dominance occurred in eight out of thirteen of the colonies; the dominant mouse occupied the majority of the floor area, but some subordinates formed small territories.

A population study of house-mice permanently inhabiting a reed-bed in South Australia.
A second intensive population study began at Turretfield in the reed-bed, where preliminary trapping supported the view that Reed-beds, if permanently inhabited, would provide ready spring-boards for the fields' re-invasion each year. Expand
Behavioural variation in wild house mice Mus domesticus Rutty: A quantitative assessment of female social organization
Variation in reproductive success among individual females was related both to their social class and variation in the quality of their nest sites, and provides an explanation for the stability of high density mouse populations provided with excess food. Expand
