Popularized by the character Timon in the invigorate Disney film " Lion King , " meerkats are often viewed as meek beast always on the lookout for danger . But within their small groups , these creatures are anything but meek — including when it comes to their couple behaviors .
Meerkats(Suricata suricatta ) live in complex , hierarchical social group or " mobs " dwell of two to 50 individuals . These groups are ruled by a dominant male and female , called the alpha pair , that have exclusive breeding right . The group also hold dependent female person who are typically closely related to the rife female ; subordinate male who are normally the materialisation of thealpha span ; and one or more unrelated immigrant male .
Meerkats progress to intimate maturity at 1 twelvemonth sometime , and males willingly leave their radical for good at around 2 class old to set about to join or take over another mathematical group . Adult subordinate female , on the other hand , are often forcefully ( and sometimes violently ) evicted by the prevalent female — they ’ll sometimes stay on the group ’s territory , sleeping and foraging alone or with other force out female until the dominant female person ’s hostility towards them subsides .

Some female person do n’t yield to the mathematical group and instead form new mathematical group , sometimes becoming thealpha female person , say Tim Clutton - Brock , a zoologist at the University of Cambridge in the United Kingdom . A female may alternatively become alpha by inherit the attitude in her KwaZulu-Natal group upon the death of the previous alpha ( by being the largest and most powerful underling ) .
" And it ’s very common that the breeding male in groups are the ones that have fight and evict other male person , " Clutton - Brock severalize Live Science .
Dominant female do n’t have much choice in their mate , given that the dominant male will do all he can to prevent her from snarl with immigrant males in the group . And the dominant male will usually only checkmate with the prevailing female , because the other sexually mature females in his grouping are his offspring .
Similar to humans , meerkats are capable tobreed year - round . But in their native household cooking stove in southern Africa , mating often coincides with menstruation of in high spirits rainfall , Clutton - Brock allege , bring that " the rainfall is unpredictable but it ’s down in the mouth between April and July . "
fall in that mating typically occurs underground , it ’s undecipherable if meerkat prosecute in many courting ritual . In some display case , the dominant male person may fight with the predominant female person and grip her by her nape until she subdues and allows him to mount her from behind .
dependent female person may occasionally couple with the immigrant male person from within the chemical group or outside of the group . But this underhand conduct comes at a price — dominant females routinely shoot down dependent females ' pups and force out the wrongdoer ( sometimes while the subordinate female person is pregnant , forcing her to abort ) .
As payment for their misdeeds , subordinate females that misplace their litters or return to the chemical group after being evictedact as wet nursesfor the dominant female ’s pups .
The dominant female has up to four litters a year and will often remain in her position until her death . When that happen , the remaining female will fight for the ruling tush , with the biggest female often coming out beforehand . The ultimate winner will experience spikes in testosterone and estrogen , as well as a rapid increase in weight and emaciated size , in the three months after take over , Clutton - Brock say .
Interestingly , late research shows that subordinate meerkat sisters in a group actively compete with each other through eating . In experiments , Clutton - Brock and his colleague fed younger sister luck of food to increase their sizing . old sisters responded by eat more on their own to grow bigger , helping them keep their shoes in the queue for the crown and the right to spawn .
