Wetland plants also need to remain stable in the soil if they deal with fast moving water that ebbs and flows. But every single adaption serves a purpose for that individual animal. The old secondary forest (60% of the habitat) is dominated by the leguminous trees. The forest habitats experiences significant dry seasons and two rainfall peaks. Young are not able to walk immediately, and must be carried for some time. Many parts of the king colobuss range are extremely vulnerable to desertification. and is now lost to history. They are strictly leaf-eaters and spend most of their time in treetops, preferring to eat the tender young leaves found there. Precipitation is typically not limiting, but may be somewhat seasonal.

The King colobuses are herbivores (folivores), their diet generally consists of soft, young leaves, growing on treetops. Red colobus monkeys are also found in East Africa, but are endangered and quite rare. In many regions they are extremely abundant, but, where their forest habitat has been altered by logging or fire, they are much less resilient than black-and-white colobus. Taxon Information Davies, G., J. Oates. (Nowak, 1999). [6] In a montane habitat colobus are known to utilise lichen as a fallback food during periods of low food availability. Some teams have proven year births whereas others have proven births in relation to the dry seasons.

They favor the highly digestible leaves, which have a relatively low level of fiber. [2] Resident-egalitarian and allomothering relationships have been observed among the female population. Habitat: Understory and middle branches of rainforest generally near to water. The olive colobus has a little head, a short muzzle and rather subdued coloration. Omissions? One of the major threats to the population of this highly endangered species is destruction of its natural habitat for private farming, commercial agriculture as well as selective logging. International Conference on Land Degradation and Desertification, Khon Kaen, Thailand.

Recent work on four Rhinopithecus species, including the GSM, shows that these colobines possess derived genetic adaptations associated with an efficient ability to metabolize fatty acids and xenobiotics and to enable the digestion of high levels of RNA derived from their stomach microbiome. Females will suckle young other than their own. King Colobus - Encyclopedia of Life Territorial calling is a typical type of aggression however may also be a warning to the group of predators.
