Abstract

This study investigates the influence of fruiting plants on the distribution of Tantalus monkeys (Chlorocebus tantalus tantalus) in the Ngel Nyaki Forest Reserve, Taraba State, Nigeria. The research aims to determine the diversity, abundance, and distribution of fruiting tree species and their relationship with the spatial patterns of Tantalus monkeys across different habitat types. Data were collected over an eight-month period, covering both dry and wet seasons, using direct field observations and ecological survey methods to assess the availability of fruiting trees, primate feeding preferences, and monkey distribution. Results indicate that the presence and abundance of specific fruiting species significantly affect the distribution patterns of Tantalus monkeys, with seasonal fluctuations in fruit availability influencing primate movement and habitat utilization. This study highlights the critical role of fruiting plants in primate ecology and underscores the importance of conserving fruit-bearing tree species to support sustainable primate populations. The findings provide valuable insights for biodiversity conservation efforts and management strategies in montane forest ecosystems.

Abstract

This study investigates the seasonal dynamics of hornbill diversity, abundance, and distribution in Bali and Gassol Local Government Areas of the central zone of Taraba State, Nigeria, a biodiverse region currently experiencing hornbill population decline. The objectives were to assess species composition, seasonal abundance, and habitat-specific distribution of hornbills across wet and dry seasons. A multistage stratified sampling method was applied, categorizing the study area into woodland savannah and open grassland as sampling sites. Hornbill surveys were conducted using the point count method. A total of 1,216 individuals representing three species—the African Grey Hornbill, African Pied Hornbill, and Red-billed Hornbill—were recorded, with higher diversity and abundance observed in the wet season due to increased food and water availability. Woodland savannah supported larger populations (753) compared to open grassland (463), attributed to its complex vegetation, nesting opportunities, and favorable microclimates. The African Grey Hornbill dominated across habitats and seasons (50–70%). Human activities, particularly bushfires, exacerbated dry season declines in open grasslands. Despite seasonal fluctuations in abundance, species richness remained stable across both habitats. Distribution patterns showed significant deviations from expected uniformity, indicating species-specific habitat and seasonal preferences. The study concludes that hornbill conservation in Central Taraba requires recognition of habitat preferences and seasonal ecological dynamics. It recommends community-based initiatives to raise conservation awareness, promote sustainable land use, and encourage practices that support hornbill population recovery and long-term biodiversity conservation.
