Abstract

Butterflies are in the order Lepidoptera, which are insect with scaled wings. Over 28,000 species of butterflies exist in the world today contributing to one-quarter of all named species on the earth. Lepidoptera is important to man and the health of the environment. Butterflies play a significant role in the pollination of crops and as aesthetics. The study assessed the diversity and abundance of butterfly species in the Taraba State College of Agricultural Science and Technology, Jalingo, Nigeria. Line transects were used to survey two study sites within the School using handheld sweep nets in January to March, 2024. Data were analyzed using descriptive statistics. A total of 1,153 individuals representing 21 butterfly species belonging to 3 families were recorded across the two study sites. Out of these, members belonging to the family Lyceanidae were the most csommon with 6 species being recorded accounting for 46.2% of the total species and 93.2% of total number of individuals collected in engineering complex while members belonging to the family Nymphalidae were the most common with 10 species being recorded accounting for 52.6% of the total species and low in the total number of individuals with 37.8% collected in staff quarters. Species richness, evenness and diversity varied from study sites to sites (R= 2.7014 – 2.0293), (e= 0.6691 – 0.6317), (H1= 1.9700 – 1.6203). It was recommended that management effort towards conservation be put in place so as to ensure sustenance of butterflies and ecosystem services derived from them, and further exploration of butterfly species be done to update this checklist.

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 assesses fish species composition and abundance at selected landing sites along the Upper Benue River Basin in Taraba State, Nigeria. Fish sampling was conducted monthly over six months (February to August 2022) at Mayo-Renewo and Lau landing sites using various fishing methods, including traps, gillnets, and hook and line. A total of 6,519 fish specimens from 26 species and 22 families were recorded. The dominant species were Tilapia galilaeus, Distichodus rostratus, and Alestes macroplepidotus in Mayo-Renewo, while Clarias gariepinus, Heterotis niloticus, and Alestes macroplepidotus were most abundant in Lau. The Shannon-Weiner Diversity Index indicated moderate species diversity, with values of -3.20703 at Mayo-Renewo and -3.28523 at Lau. Length-weight relationships showed positive allometric growth in most species, with a mean condition factor (K) above 1, indicating a favorable aquatic environment. Physicochemical analyses revealed variations in temperature (21.46–24.58°C), dissolved oxygen (6.1–8.4 mg/L), pH (8.22–8.62), electrical conductivity (340–840 µS/cm), total dissolved solids (170–556 mg/L), and turbidity (192–320 NTU). Statistical analysis (ANOVA) confirmed significant seasonal differences in these parameters (p < 0.05). The findings highlight the ecological health of the river and the importance of continuous monitoring to sustain fish biodiversity and productivity.

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.
