Abstract

Arthropoda is a very large phylum in the subdivision Invertebrata, playing a significant role in the ecosystem, it includes the very important class, Insecta, which are the most diverse and most abundant group of arthropods found virtually everywhere (ubiquitous) in large numbers, constituting nuisance to man and its livestock and crops while playing invaluable roles in ecosystem provisioning and services, as well as support. However, despite the recognized significance of termites in tropical ecosystems, comprehensive studies on termite diversity within Okomu National Park (ONP) is sparse. This study, therefore, identified termite species and evaluated their diversity within termite mounds across ranges within ONP. Termite samples were collected from representative mounds across the four ranges, Arakhuan, Igwuowan, Julius Creek, and Babui Creek in ONP, hand-picked using active search and baiting methods, then preserved in 80% alcohol for laboratory identification. Soil samples were extracted near mounds and analyzed for pH and fertility levels using a 4-in-1 soil tester. Pearson correlation analysis was employed to determine species diversity patterns associated with termite mounds across different habitat types. Macrotermes natalensis was the dominant termite species identified, with different maturity stages observed across various mound structures.  The study elucidates termite impacts on protected environments, informing enhanced conservation strategies.
