Conflict between background matching and social signalling in a colour-changing freshwater fish [PDF]
, 2016 The ability to change coloration allows animals to modify their patterning to suit a specific function. Many freshwater fishes, for example, can appear cryptic by altering the dispersion of melanin pigment in the skin to match the visual background ...

When are females dominant over males in rats (Rattus norvegicus)?
Behavioral Ecology and SociobiologyAbstract In group-living animals, males are assumed to be dominant over females when they are larger than females. Despite this, females have sometimes been proven to be dominant over some males via the winner-loser effect, which becomes stronger when the intensity of aggression in the group is higher.

Victims of infanticide and conspecific bite wounding in a female-dominant primate: a long-term study. [PDF]
PLoS ONE, 2013 The aggression animals receive from conspecifics varies between individuals across their lifetime. As poignantly evidenced by infanticide, for example, aggression can have dramatic fitness consequences.

Infanticide and infant defence by males--modelling the conditions in primate multi-male groups [PDF]
, 2004 Infanticide by primate males was considered rare if groups contain more than one adult male because, owing to lower paternity certainty, a male should be less likely to benefit from infanticide.
