Manjaribe (2016) Eulemur
sanfordi belongs to a group of endemic lemur species in Amber
Mountain National Park, Madagascar. The diet of E. sanfordi
and the effects of gut-passage on the germination of seeds were studied
to determine how the feeding activities of this lemur affect the
integrity of this forest ecosystem. A specific group of E. sanfordi
was observed and monitored during 396 hours from the end of the dry
season to the beginning of the rainy season. Field observers recorded
the food items taken, plant species consumed, plants organs preferred
and the forest layer in which food was harvested by this species. Seeds
were sorted from discarded food items left by the group of E.
sanfordi being followed. Germination tests allowed analysis of the
germination potential of the collected seeds. Feeding
times for E. sanfordi varied significantly (p =
0.01) across the study period (from September to February). Their
feeding activities were intense between December and February, peaking
in January (90%). They spent more time eating fruits than other organs
of plants. Feeding patterns on ripe fruit also varied significantly (p
= 0.01) during the study. E. sanfordi
consumed 34 plant species, with 21% from the family of Moraceae. This
group of observed lemurs consumed 9 to 17 plant species per month and
preferred trees greater than 10 m tall. Overall, seeds that passed
through the gut of these lemurs had significantly higher germination
rates than those seeds that did not (t = 5.87, p =
0.02). The average latency period of passed and control seeds ranged
from 35 to 83 days and from 52 to 95 days, respectively. E.
gut passage provides better germination of seeds species they consumed.
This could contribute to the conservation of plant diversity. E.
sanfordi play an important role in Amber forest ecosystem to
preserve some endemic species.
