Misc.: The lemurs biggest factor in its decline in
numbers is the continuous and rapid deforestation by clearing for industry and
plantations, timbering for local use and export, and slash and burn
agriculture.
There are 2 species of
ruffed lemurs - Black and White Ruffed and Red Ruffed. Our lemurs are a
hybrid, referred to as Tri-Colored Ruffeds and are a cross between the two.
Size and Appearance: Ruffed lemurs are the
largest of the living "lemuridae." They have a head and body
length of 39-45 inches, weighing between 7-9 pounds. Our lemurs have the
colors of both species, black, white and red. Both have solid black
faces and ruffed "collars" around their faces of varying
colors.
Habitat: Ruffed lemurs are
aboreal and spend their time in the high canopy of the seasonal rainforests on
the eastern side of the island. They are diurnal and are active only in
the daylight.
Distribution: Eastern Madagascar.
Reproduction and
Offspring: Ruffeds mate from about
May to July and give birth during the wet season when fruit is plentiful. Parenting in this species of lemurs is unique in that
no single infant is invested in but instead, females bear litters of multiple
offspring. Males also play a role in the parenting of the offspring especially
in smaller groups where the certainty of paternity is high. In larger groups,
the chance of a female mating with more than one male increases as does uncertainty
in paternity. This tends to decrease the level of male care of offspring.
Instead of clinging to the mother, offspring are placed into a nest which is
guarded by both parents.
Social System and
Communication: This prosimian typically
lives in small, matriarchal groups
of 2-16 individuals, but group sizes of up to 32 have been recorded. Its diet
consists primarily of fruit, nectar, and pollen. Leaves and seeds may be eaten
when fruit becomes scarce. Red ruffed lemurs will sometimes form large groups
during the wet season when food is plentiful. .They will all find one food
source and forage together as a group. During the dry season they will often
separate and find food on their own when the fruit is hard to find. This is
very odd because most other diurnal lemurs will stay together and forage in
large groups even during the dry season. Field studies suggest that red
ruffed lemurs, like black-and-white ruffed lemurs, may be found in monogamous
pairs or in small, organized groups. Individuals out in forest communicate
through loud booming calls, which can be heard for miles.
Conservation Status: Both species in the wild
are critically endangered.
