Genetic Diversity and Inter-Specific Interactions in Family Arecaceae

Background and Objective: Palm trees are most significant in the nutrition and ecological sustainability of man. This study aimed to evaluate the significance of taxonomic diversity and species interactions (epiphytes) among members of the Arecaceae family. Materials and Methods: Two study locations (South-Core and North-Core) at Joseph Sarwuan Tarka University, Makurdi, Benue State, Nigeria, were considered. A simple random sampling technique based on standard procedures for ecological and taxonomic assessments was employed. A transect distance of 100 by 100 m was measured in five plots in each of the study locations following the utilization of a non-destructive method of harvest. Studied species displayed varied foliar and floral macromorphological characteristics, which were qualitatively and quantitatively measured. ResμLts: Elaeis guineensiswas the most dominant (Simpson, 0.43), and richest (Magalef, 28.84) species evaluated. Cocos nucifera was the most diverse (Shannon-Weiner, 0.37) in both locations. Also, inter-specific interactions evaluated suggested most epiphytes preferred Elaeis guineensis.The most dominant, diverse, and richest epiphyte in this study was Polysticlium munitum. Analysis for carbon storage and species density showcased the ecology of species. Phylogenetic relationship revealed Cocos nucifera, Elaeis guineensis,andCycas revoluta are closely related. Conclusion: The ecological and taxonomic significance of palm species is negligible but of great impact on the ecosystem.
