| dc.description.abstract | The population status and distribution of gelada baboon in Cliff Azwa and Arego was investigated and test statistics was applied to age-sex categorical variable. The study area was stratified into five study blocks namely Aba Tasho, Aba Gude, Doro Mezeleya, Azwa and Dikule genet. The study was carried out from August, 2008 to March, 2009. Data on movement, distribution and human gelada interaction were collected in the area based on the questionairre survey and field observation. Data were analyzed using descriptive statistics, and responses were compared using t-test and oneway ANOVA to compare age-sex categorical variables. The population size and abundance of geladas in the area was determined from total (direct) count. A total of 338 individual geladas were recorded with a density for the entire region of 0.071 geladas/km2 and actual density specific for the home ranges was 6.22/km2. Of this, males were 74, females 186 and juveniles 78. There was significant difference (P<0.05) between males and females, males and juveniles and females and juveniles. Large number of infants indicates that the population is increasing. Geladas spent more time feeding (57.26 %). Other activities such as vocalization, defecation and looking at the observer were the least (2.33%) in their time budget. They depend on grass during the wet season (82.77%) but during the dry season, they fed on roots (38.71%) and leaves (38.5%) in larger proportion and almost in equivalent amount. There are significant differences (P<0.05) on the type of food taken during the dry and wet seasons. Key words: abundance, body size, distribution, extinction, Gelada baboon, habitat, human activities, juvenile. | en_US |
