Social organization in the aboriginal house mouse, Mus spretus Lataste: behavioural mechanisms underlying the spatial dispersion of competitors
Article Abstract:
A study on the role of social defense among rodents in determining their spatial dispersion in grasslands shows that the M. spretus species fiercly prevents the intrusion of others in their territory. Results also show that the competition to dominate over suitable sites is more fierce than theaggression to drive competitors away. Mice use odor cues to identify and compete for dominance over occupied areas. Once dominance relationships are established the mice become mutually tolerant. This also suggests intra-sexual competitive behavior among different groups of M. spretus.

The competing countermarks hypothesis: Reliable assessment of competitive ability by potential mates
Article Abstract:
Scent marking over a scent mark already present is usually termed countermarking, and such marks provide a continuous record of competitive challenges between conspecifics. Scent marks in the territories of neighbouring male house mice were manipulated to test the hypothesis that females prefer males that countermark in their territory over those whose own marks are partially contermarked by a competing male. Oestrus females were found to be more strongly attracted to approach territory owners.

The effects of cage cleaning of aggression within groups of male laboratory mice
Article Abstract:
A study of the effects of cage cleaning on captive laboratory mice revealed that the best strategy to curb aggressive behavior in mice is to shift them to totally clean cages. Aggression levels peaked in mice when they were shifted to clean sawdust mediums in their previously inhabited unclean home cages.
