Effect of abiotic factors on understory community structures in moist deciduous forests of northern India

Floristic Biodiversity and Stem Volume of Kambui Forest Reserve, Kenema District, Sierra Leone.

“…The Importance Value Index (IVI) was determine using the (Kent and Coker (1992), Pielon (1975), Phillip (1983, Curtis, 1950;Mishra 2013;Mclntosh 1950 andMichael (1990) Where: D = is the dominance of the index, P i = is the proportion of i th species, S = is the number of individuals of all the species.…”

“…When the floristic biodiversity of a forest is being degraded it stem volume strength is affected because the volume is increased with the number of trees in a stand as well as the diameter at breast height of trees. In recent times, scientific documentation of biodiversity has assumed immediate research priority (Singh, 2012) because biodiversity maintenance is one of the major goals to attain forest sustainability while assessment of forest community composition and structure is very helpful in understanding the status of tree population, regeneration, and diversity for conservation purposes (Osorio et al 2009;Mishra et al, 2013). In the last few decades, the world has realized that the conservation and sustainable use of biodiversity are the principal pillars for sustainable development.…”

“…The percentage value of the relative frequency, relative density and relative dominance are summed up together and this value is designated as (IVI) of the species. Density = Index (H):-Shannon-Wiener diversity index (Shannon and Wiener, 1963, Kent and Coker 1992 and Gaines et al, 1999) was calculated from the IVI values using the formula: is Shannon-Wiener Index of diversity, P i = the proportion of individual of a species, S = number of species in the community, ∑ = summation symbol, In = Natural logarithm to the base e 428 The Simpson's Diversity Index (D):-Simpson diversity was calculated by methods of(Mishra, 2013, Simpson, 1949.…”

An indirect method of estimating leaf area index in a tropical deciduous forest of India

“…Our values from dry miscellaneous and sal mixed forests are also similar with the LAI-2000 measurements in three pre-montane to lower montane rainforests in South Ecuador (5.1 at 1050 m, 4.6 at 1540 m and 3.9 at 1890 m a.s.l., Moser et al, 2007) and in mountain forests in Sabah, Borneo (5.6 at 700 m, Kitayama and Aiba, 2002). The comparatively low LAI values in the teak plantations may in part result from the trees being shorter, being of comparatively young age and without having middle storey tree layers and relatively poor soil organic carbon in that region (Mishra et al, 2013). Teak plantations showed lowest LAI values due to lesser contribution of the poorly developed understory layer to the stand total LAI (Montgomery, 2004).…”

Variation in structure and composition of two pine forests in Kailash Sacred Landscape, Nepal

“…T he structure of a forest is determined by biotic and abiotic components (Behera et al, 2012;Mishra et al, 2013), along with human disturbance (Sanderson et al, 2002;Kareiva et al, 2007). Disturbance and biological processesare significant factors determining forest stand development (Franklin et al, 2002).…”
