A forest is a highly organised system in which dominant elements are plants, in particular trees, forming a canopy cover and playing the role of its major constituent species, and animals with their habitats. A great variety of life forms in the forest are linked with its multi-layered structure, which is the result of varying amounts of sunlight reaching the understory layer. This has a decisive impact on the distribution of species depending on their shade tolerance.

A comprehensive global database of forest ecosystem carbon budget variables fluxes and stocks , ecosystem traits standing biomass, leaf area index, age , and ancillary information management regime, climate, soil characteristics has been compiled for sites. The database fills an important gap for model calibration, model validation, and hypothesis testing at global and regional scales Luyssaert et al. This database is structured by site i. It contains carbon budget variables fluxes and stocks , ecosystem traits standing biomass, leaf area index, age , and ancillary information management regime, climate, soil characteristics for sites from eight forest biomes. Flux estimates were included in the database when they were based on direct measurements e.

The purpose of this paper is to give a general description and analysis of the key factors important for forest biodiversity, and to show the development of a strategy for choosing an indicator methodology for assessment of forest biodiversity. Different biodiversity indicator schemes methodologies have been developed recently and all should be capable of being adapted to the specific objectives of biodiversity assessment and to the forest types concerned. A forest ecosystem comprises three main components: structure e.

A forest is an area of land dominated by trees. It does not include land that is predominantly under agricultural or urban land use. Forests are the dominant terrestrial ecosystem of Earth, and are distributed around the globe. The largest part of the forest 45 percent is found in the tropical domain, followed by the boreal, temperate and subtropical domains. Net primary production is estimated at

This revision maintains the position of Forest Ecosystems as the one source for the latest information on the advanced methods that have enhanced our understating of forest ecosystems. Further understanding is given to techniques to explore the changes in climatic cycles, the implications of wide-scale pollution, fire and other ecological disturbances that have a global effect. The inclusion of models, equations, graphs, and tabular examples provides readers with a full understanding of the methods and techniques.

An organism is always in the state of perfect balance with the environment. The environment literally means the surroundings. The environment refers to the things and conditions around the organisms which directly or indirectly influence the life and development of the organisms and their populations. Organisms and environment are two non-separable factors. Organisms interact with each other and also with the physical conditions that are present in their habitats.
