| dc.description.abstract | The study identified the woody species, determined the abundance and diversity of selected macroarthropods (millipedes, termites, beetles and bees), the soil physico-chemical properties and examined the relationship between them in Akure forest reserve, Aponmu. This was with a view to providing information on the effect of different woody species on the abundance and diversity of selected macroarthropods. The study was carried out in four physiognomies comprising plantations (Tectona grandis, Gmelina arborea, Taungya) and secondary regrowth forest.Four plots of 25 m x 25 m were randomly selected from a sample of 100 m x 100 m for sample collection.All woody species were enumerated and identified and composite soil samples were collected at a depth of 0-30 cm using a soil auger from five sampling points. The soil samples were bulked and analyzed for soil pH, organic matter, and total nitrogen. Pitfall traps were used for beetle collection, millipede was collected by hand picking and bee specimens were trapped using window intercept, while termite collection was done by transect method.Data collected were analyzed using descriptive statistics and analysis of variance. The results showed that woody species diversity and abundance were fewer in planted forests relative to secondary regrowth forest. Secondary regrowth forest had 83 woody species and Shannon-Wiener Index(4.0589); Tectona grandis plantation had the least number of woody species (16) while Taungya plantation had the least Shannon-Wiener (2.1607) Index. Out of the twenty-seven (27) species of selected macroarthropod encountered, Taungya plantation had the highest (20 species), while the secondary regrowth forest and Gmelina arborea plantation had the least (14 species). Taungya plantation was richest in beetle specimens with a mean density (8.5±1.85); Gmelina arborea plantationwas richest in millipede specimens (16.75±1.98), whileTectona grandis plantation had the richest in termite (124.75±23.63) collection. Comparative analyses showed that no significantly (p < 0.05) differencein the abundance of the selected macroarthropod across the plant physiognomies. The results of the soil analysis showed that Taungya plantation soil was slightly alkaline (7.32±0.31), with highest organic matter (OM) (2.14±0.16)% and total nitrogen (TON) (0.048±0.00)%, while the least OM and TON was recorded in Tectona grandis plantation (5.69±0.20 1.18±0.12, and 0.035±0.01%) respectively. There was a positive relationship between total organic matter (TOM) and total organic carbon (TOC) (0.999), total nitrogen and TOC (0.969), TN and TOM (0.970) in Gmelina arborea plantation. There wasa negative relationship between termite and woody species (-0.981) and positive significant relationship between TOM and TOC (0.999), TN and TOC (0.993), TN and TOM (0.993) in the Tectona grandis plantation. In the Taungya plantation positive relationship was recordedbetween millipede and pH (0.975), TN and TOC (0.985), TN and TOM (0.984), TOM and TOC (0.999). A negative significant relationship exist between termite and TOC (-0.959), Termite and TOM (-0.951) while a positive significantoccurred between TN and TOC (0.972) in secondary regrowth forest. This study concluded that woody species affected abundance and diversity of the selected macroarthropods and soil chemical characteristics. | en_US |
