INSECTS INJURIOUS TO FOREST TREES IN SOUTH AFRICA

Wildfires in South Africa; Cherry Trees in Japan

We consider two challenging ecological problems and show how they are naturally investigated using spatial survival models with time varying covariates. The first problem involves explanation of the occurrence of wild fires. This process is of interest because over half of the world’s terrestrial ecosystems depend on fire to maintain ecological structure and function and the ecological role of ...

Species Diversity of Trees and Forest Floor Plants in Oriental beech Forest Types of Shastkalate Educational and Research Forest, Gorgan)

Trees are the most important biological elements of forest ecosystems. The variability of the tree species composition inhabiting in the Oriental beech forest, not only forms different forest types but also has a remarkable impact on the species diversity of forest floor plants, due to the existence of trees in the overstory layer. In this research, forest types of an an Oriental beech were ide...
