Asynchronism in leaf and wood production in tropical forests

Factors Affecting Yield and Composition of Milk

The variation in composition and daily yield of milk is a regular phenomenon in all milking animals. Broadly, the factors which are responsible for such variations can be divided into (1) Physiological, which will be governed by the genetical make up and (2) Environmental, such as age, number of previous lactations, pregnancy, nutrition status, etc. The dairyman has hardly got any control over ...

Study of ectomycorrhizal fungi with beech trees in highland beech forests (Farim, Mazandaran province)

In this study, the ectomycorhizal fungi from beech trees in highland beech forests of Farim (Mazandaran province) were identified based on extraction of DNA from roots and sequencing the ITS region of nuclear ribosomal DNA. For this purpose, in the altitude of 1500-2100 meters A.S.L, 30 plot and one plant per each plot were selected randomly and samples were taken from roots in depths of 10 cm ...

Does one model fit all? Patterns of beech mortality in natural forests of three European regions.

Large uncertainties characterize forest development under global climate change. Although recent studies have found widespread increased tree mortality, the patterns and processes associated with tree death remain poorly understood, thus restricting accurate mortality predictions. Yet, projections of future forest dynamics depend critically on robust mortality models, preferably based on empiri...
