Biomass and leaf area equations are often required to assess or model forest productivity, carbon stocks and other ecosystem services. These factors are influenced by climate, age and stand structural attributes including stand density and tree species diversity or species composition. However, such covariates are rarely included in biomass and leaf area equations. We reviewed the literature and built...
Owing to the growing sensitivity of forests to drought under the warming climate, more attention should be paid to the role of soil drought, plant–plant interactions, tree species and structural diversity, and other abiotic factors on the crown die-back of trees. We studied how permanent soil water stress had impacted on crown die-back of beech trees (Fagus sylvatica L.) at their drought limit in...
Quantum efficiency of p-n junction solar cell is analytically calculated with incorporation of the effect of Quasi-Fermi level generated after showering of photon. Result is derived after simultaneous solution of carrier transport equations involving both drift and diffusion mechanism, and carrier continuity equations involving generation rate. It is observed that slightly higher efficiency is obtained...
