Unravelling the chemical basis of competitive scent marking in house mice
Article Abstract:
The protein fraction of male mouse urine contains the chemical signals that prompt competitive countermarking, according to research investigating the role of proteins and volatiles in stimulating the countermarking response of competitors to the urine scent marks of other male house mice. An unusual object entering a mouse's home enclosure will prompt urine marking, but the only fraction of urine that prompted more countermarking than this novelty response was that containing the urinary proteins and their associated volatile ligands.

Housing and welfare in laboratory rats: time-budgeting and pathophysiology in single-sex groups
Article Abstract:
Studies on Alderley Park rats, Rattus norvegicus, show clear cut relationship between aggressive social pressure, time budgeting, physiology and early organ histology changes in males and females. Both males and females differ in the number of aggressive acts in response to social pressure. Females spend more time moving around the enclosure and stretching up the walls. Corticosterone levels are correlated with subsequent aggressive behavior.

Housing and welfare in laboratory rats: Effects of cage stocking density and behavioural predictors of welfare
Article Abstract:
Male and female Alderley Park rats were housed in single-sex groups to study the effects of group size on competitive behavior, timing budgeting and changes in serum testosterone. Pathophysiology in both sexes showed strong and highly specific links with behaviours indicating attempts to escape from cages. Aggressive grooming was linked with pathophysiological responses only in males.
