how is the social organization of orangutans. Pelage: Course, wiry hair; shade ranges from pale brown to near black. In so doing, the study helps to understand the nature of the environmental factors such as the disturbance levels, foraging opportunities, food availability, and habitat quality of the species for future management and conservation efforts, and the sustainability of the study area biodiversity. Primates may respond quite differently to forest disturbance, fragmentation, and related edge effects, which make the long-term survival of a particular primate species in an altered habitat depending on its specific habitat requirements [8, 35]. The Ashangi group is composed of alkaline basalts interbedded with pyroclastics and rhyolites [40]. G. Belay and A. Mori, “Intraspecific phylogeographic mitochondrial DNA (D-loop) variation of Gelada baboon, G. Belay and T. Shotake, “Blood protein variation of a new population of gelada baboons (, T. R. Defler, “The time budget of a group of wild woolly monkeys (, K. Milton, “Physiological ecology of howlers (. Known and identified food species consumed by members of geladas were recorded in the field and unidentified species were collected, named by their local name, pressed, and taken to Addis Ababa University National Herbarium for further taxonomic identification. Gestures such as staring, smiling, and head-bobbing serve as threat displays, whereas nose-touching and lip smacking show friendly attitude. The authors would also like to express their warmest appreciation to Basona Worana Woreda Agricultural and Rural Development Authority for giving permission to conduct this study. 3-4 years. This particular Monkey is often argued to be an Ape instead. (iii)Subsequent studies should be conducted to determine the trajectory of a population and behavioural ecology of geladas in the area. D.

We will be providing unlimited waivers of publication charges for accepted research articles as well as case reports and case series related to COVID-19. The gelada baboon (Theropithecus) is found in the highlands of Ethiopia. The vegetation type of the study area is mainly scattered shrubs interspersed with annual and perennial herbs in the sloppy area. Scoot with hindquarters along the ground while foraging. It occurs in the provinces of Tigray, Wollo, Gondar, and Shoa between latitudes 9° and 14° N in rocky gorges and precipices at altitudes between 2350 and 4400 m asl [14–18]. Wide ranges of factors such as climatic conditions, food availability and quality, and human disturbances influence the diurnal activity budget of geladas in the study area. The data used are available from the corresponding author upon request. Currently, there are about 315 species of mammals in Ethiopia, of which about 36 (11.4%) are endemic [4]. A.

According to Gippoliti [19], the gelada distribution is still imperfectly known at the moment, and apparent gaps in its distribution range warrant further field research. [57] on Arsi geladas where geladas exhibited themselves on feeding about 42%. During the wet season, however, green grasses were plenty and geladas satisfy their energy demand.
