Troop fission in wild ring-tailed lemurs (Lemur catta) at Berenty, Madagascar

Article Abstract:

The troop fission in primates is reported mostly for female bonded cercopithecoid monkeys where the breakaway of subordinate kin group females initiates troop fission. Male-female association did not cause the troop fission and males play no apparent role in troop fission in ring-tailed lemurs but this difference appears to be attributed to a unique trait of lemurs, female social dominance.

Variation in fecal testosterone levels, inter-male aggression, dominance rank and age during mating and post-mating periods in wild adult male ring-tailed Lemurs (Lemur catta)

Article Abstract:

A study to examine the mean fecal testosterone (fT) levels and intermale aggression in wild adult male Lemurs (Lemur catta) during mating and post-mating seasons is conducted. Results show a strong positive relation between male testosterone level and male-male competition for access to receptive females during breeding season.

Attacks on wild infant ring-tailed lemur (lemur catta) by immigrant males at Berenty, Madagascar: Interpreting infanticide by males

Article Abstract:

Wild infant ring-tailed lemus (lemur catta) was attacked persistently by immigrant males, which disappeared when severe wounds were observed at Berenty Reserve, Madagascar. It suggests that ring-tailed lemur females rarely defend infants cooperatively against lethal attack by immigrant males.
