Natural forest ecosystems are very important because of their potential and primary role in carbon (C) sequestration. However, it is not very clear that whether Functional Trait Diversity (FTD) enhances C stocks in them due to the trait values of the most abundant species (the mass ratio effect; measure as a Community Weighted Mean (CWM) and/or the variety of trait values (the niche complementarity effect; measure as a Functional Divergence (FD) within an ecosystem. In this study, I reviewed the most recent, critical, empirical and original research studies about FTD-C stocks relationship to understand the effects of CWM and FD on C stocks in natural forest ecosystems. The results of their studies suggest that strong dominance by tall and conservative species, rather than a set of coexisting species with diverse heights and exploitative nature, results in greatest C stocks in natural forest ecosystems. Thus, functional dominance (CWM effect) rather than FD effect has strong influence on C stocks in natural forest ecosystems. In conclusions, these evidences reflect that presence of dominant species will finally diminish functional divergence. Therefore, further research is needed to include the abiotic and biotic factors of an ecosystem in the conceptual model to critically test the FTD model of C stocks for full understanding.

Damage of fruits by insect pests is one of the major problems faced by fruit sellers in many parts of the country. African star apple Chrysophyllum albidum G.Don. is one of the indigenous fruits that are highly damaged by insect pests during the fruiting season and in storage. A survey of markets and environs were carried out in Ibadan metropolis during the fruiting seasons for two years to determine the associated insect pests and the extent of damage done to C. albidum. Samples of ripe fruits were randomly collected from seven markets and homestead trees at different locations in Ibadan metropolis. Samples were examined in the laboratory at the Federal College of Forestry for damage and the causative agents were identified. Collections made periodically from green fruits to ripening in orchard at Forestry Research Institute of Nigeria showed that infestation of unripe fruits was by scale insects Coccus hesperidum L. while the ripe fruits were mainly attacked by fruit flies (Drosphillla spp. and Cerattis capitata Weid). Infestations were most severe in the market samples than the homestead tree samples. Severity of infestation ranged between 10-35% of the sampled fruits during the periods of the study. There were no significant differences (p>0.05) in the number of fruit fly species collected from different markets or from trees in the sampled locations. There were positive and negative correlations between the ripeness of fruits and attack by fruit flies and scale insects respectively.

A phytosociological assessment was done in Terai-Bhabar region of the central Himalaya to understand the current status of a monotypic genus Indopiptadenia. Identification of different forest communities within the region was also accomplished. Cluster analysis and PCA revealed five forest communities (i.e., sal miscellaneous forest, sal dominant forest, lowland miscellaneous forest, teak plantation and Indopiptadenia population) on the basis of their species composition. Out of these 5 communities, Indopiptadenia population attracted more attention due to its small and declining population. The unique habitat of this small population found chiefly on gravely-sandy soil along the water streams edges places it before the natural threats of floods and cutting of river banks. The lowest tree density (440.00 stem haG1) and basal cover (19.35 m2 haG1) values were exhibited by this plant community. This suggests that the population of Indopiptadenia is more exposed forest community in comparison to others and faces higher degree of anthropogenic pressures for their fodder and timber values.

Climate is the prime factor that influences forest growth, composition and distribution. There are many ways to determine forest productivity in terms of climatic factors like temperature, precipitation, length of growing season, effective sun hour etc. When edaphic and topographic factors remain constant, climatic factors become more prominent for forest growth and productivity. Among many methods of assessment of forest productivity, Paterson’s Climate Vegetation Productivity (CVP) index-requires less efforts and fieldwork to determine productive potential of any forest land. The index is not stand and species specific, hence, it can be put in use for overall assessment of the forest and vegetation productivity in any country, region and continent or even for the globe. This index may be used for comparison of forest lands, even non-forested lands with higher index value that may be established as a productive forest.
