Alpha Diversity And Species Status Of Uneven Forests In Eco-Zones Of Taraba State, Nigeria, Dau Henry Japheth, Joseph A. Ugbe, Jerry I. Alfa Sep 2023

Alpha Diversity And Species Status Of Uneven Forests In Eco-Zones Of Taraba State, Nigeria, Dau Henry Japheth, Joseph A. Ugbe, Jerry I. Alfa

Journal of Bioresource Management

Alpha diversity indices quantify the uncertainty in predicting the species identity of an individual. Quantitative indices on species composition and distribution are vital to understanding the trend and species status of an ecosystem for conservation management. However, among the forest ecosystems in Taraba state, Bakin Dutse and Wasaji uneven forests are one of the least studied areas, especially in terms of tree species status. This research work aims at assessing alpha diversity and species status of selected uneven forests in Taraba state, Nigeria; to provide baseline knowledge for conservation management. In total, 102 tree species from 74 genera and 41 …

The inventory of the carabid family at two forest sites in the Belezma national park namely an oak grove site and a cedar site during a period ranging from May 2017 to April 2018, has shown the counting of 27 taxa that have been inventoried by Barber pitfall traps. The results showed that the Quercus ilex site has slightly more species (25 species) compared to the Cedrus atlantica one (23 species). However, the Harpalinae subfamily is quantitatively the better one represented at both sites. The Shannon and Simpson indices report slightly higher figures in the Cedrus atlantica site with respectively …
