GLOBIO Model
The GLOBIO Model is a global biodiversity model developed by the Netherlands Environmental Assessment Agency to support policy makers by quantifying global human impacts on biodiversity and ecosystems An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment.

Netherlands Environmental Assessment Agency
The Netherlands Environmental Assessment Agency ( - abbr. PBL) is a Dutch research institute that advises the Dutch government on environmental policy and regional planning issues. Operating as an autonomous entity within the Dutch Government organization, specifically under the Ministry of Infrastructure and Water Management. While primarily associated with the Ministry of Infrastructure and Water Management, PBL's expertise is also sought by other government departments, including the Ministry of Economic Affairs, the Ministry of the Interior and Kingdom Relations, the Ministry of Agriculture, Fisheries, Food Security and Nature, and the Ministry of Foreign Affairs. The research fields include sustainable development, energy and climate change, biodiversity, transport, land use, and air quality. It is one of three applied policy research institutes of the Dutch government, the other two being ''Centraal Planbureau'' (CPB), and The Netherlands Institute for Social Research (SC ...

Biodiversity
Biodiversity is the variability of life, life on Earth. It can be measured on various levels. There is for example genetic variability, species diversity, ecosystem diversity and Phylogenetics, phylogenetic diversity. Diversity is not distributed evenly on Earth. It is greater in the tropics as a result of the warm climate and high primary productivity in the region near the equator. Tropical forest ecosystems cover less than one-fifth of Earth's terrestrial area and contain about 50% of the world's species. There are latitudinal gradients in species diversity for both marine and terrestrial taxa. Since Abiogenesis, life began on Earth, six major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic aeon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosion. In this period, the majority of Multicellular organism, multicellular Phylum, phyla first appeared. The next 400 mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecosystem
An ecosystem (or ecological system) is a system formed by Organism, organisms in interaction with their Biophysical environment, environment. The Biotic material, biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal Environmental factor, factors. External factors—including climate—control the ecosystem's structure, but are not influenced by it. By contrast, internal factors control and are controlled by ecosystem processes; these include decomposition, the types of species present, root competition, shading, disturbance, and succession. While external factors generally determine which Resource (biology), resource inputs an ecosystem has, their availability within the ecosystem is controlled by internal factors. Ecosystems are wikt:dynamic, dynamic, subject to periodic disturbances and always in the process of recovering from past disturbances. The tendency of an ecosystem to remain clo ...
