Effects of resource distribution on activity and territory defence in house mice, Mus domesticus
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 the territory according to the location of different resources? We examined whether wild-caught male and female house mice increased aggression towards intruders of the same or […]

Here, using female C57BL/6J mice, we investigated whether the way that environmental enrichments are distributed affects the risk of negative interactions between individuals and whether familiar siblings are less […]
