Abstract

Aims: Effect of tree species composition and food selectivity on the population density of the Sclater’s guenon was carried out to determine how habitat composition and food preferences affect population density of the Sclater’s monkeys in the study area. Place and Duration of Study: The study was carried out in forest patches of Lagwa community in Aboh-Mbaise Local Government Area, Imo State (December 2019-November 2021). Study Design: The point centered quarter method was used to collect data on trees species, while the visual observation and line transect methods was used to collect data on food preference and population density of the monkeys. Methodology: The research was carried out within the wet and dry season. Faecal examination was used for collecting information on plant and fruit species consumed. Results: The most dominant tree species were Khaya ivorensis and Treculia africana with important value index (IVI) of 35.13 and 26.73 respectively, while Bosqueia angolensis was the least dominant species with IVI of 0.99. Tree species with diameter at breast height class of 41cm and above were absent in Eziudo, Obo and Umunekere communities. Dacryodes edulis, Elaeis guinensis, Mangifera indica and Musa balbisiana were the most consumed plant species. The mean troop sizes were 3.21±1.42 for the dry season and 2.78±1.25 for the wet season, with troop density for both seasons as 0.03±0.02. Conclusion: The findings presents the relationship between the Sclater’s monkey’s diet and their habitat, and how habitat changes can cause changes in the feeding pattern, type of food and meals consumed. Sensitization campaigns and provision of alternative food sources for humans can reduce disturbance of the habitat and further sustain the population of the monkeys.
