Research overview: fission-fusion dynamics in lion prides

Although a pride is a stable social unit, its members are rarely all together; lions move in subgroups that split and merge in a fission-fusion pattern. This overview surveys research on how pride members distribute themselves across the territory according to prey, water, cub-rearing needs, and the threat of intruders, reuniting periodically through roaring and scent. It discusses how subgroup size affects hunting success and vulnerability, and how communal cub creches anchor females. The topic refines the popular image of the pride as a constant group, showing instead a fluid society held together by long-term bonds and recognition across temporary separations.
