This process which has been reproduced using an ecosystem model.

He is best known for his pioneering work in the development of open ocean plankton ecosystem models.

A traditional ecosystem model attempts to approximate the real system as closely as possible.

After establishing the components to be modeled and the relationships between them, another important factor in ecosystem model structure is the representation of space used.

Liebig's Law has been extended to biological populations (and is commonly used in ecosystem models).

For example, below-ground resource allocation is driven by nitrogen or water availability in many forest ecosystem models.

This work led to the development by Fasham and colleagues of a seminal open ocean plankton ecosystem model.

Simulation of geographical trends in Chowdhury ecosystem model.

Digital ecosystem models are informed by knowledge of natural ecosystems, especially for aspects related to competition and collaboration among diverse entities.

Ecosystem models are mathematical representations of ecosystems.

Computer simulations using the Chowdhury Ecosystem Model did not find support for the rule.

In ecosystem models, population sizes (or concentrations) of plants, animals and resources (nutrients, organic material) are typical state variables.

Tilman et al. demonstrated that extinction debt could occur using a mathematical ecosystem model of species metapopulations.

Remotely sensed data, combined with information from ecosystem models, offers an unprecedented opportunity for predicting and understanding the behavior of the Earth's ecosystem.

Ecosystem models have applications in a wide variety of disciplines, such as natural resource management, ecotoxicology and environmental health, agriculture, and wildlife conservation.

A terrestrial ecosystem model driven by satellite measures of vegetation greenness (NDVI).

Areas of research range from genomic surveys, to studies of the genetic basis of marine microbial biogeochemistry to building ecosystem models.

Arctic biota/vegetation (ecosystem models)

Parallel to PCLake, PCDitch was developed, which is an ecosystem model for ditches and other linear water bodies.

From this empirical base he went on to develop ecosystem models that explained the annual cycle of plankton ecosystems, most notably in his analysis of the Georges Bank region.

POM proponents posit that an ecosystem is so information-rich that an ecosystem model will inevitably either leave out relevant information or become over-parameterized and lose predictive power.

Subsequent joint work with colleagues in Princeton University led to the ecosystem model being one of the first to be applied within a general circulation model of the North Atlantic.

A theoretical ecosystem model recently demonstrated that greater access to organic nitrogen by mycorrhizal fungi should slow decomposition of soil carbon by free-living decomposers by inducing nutrient limitation.

Ecosystem models are formed by combining known ecological relations (e.g. the relation of sunlight and water availability to photosynthetic rate, or the relation between predator and prey populations) with data gathered from field observations.

Because of this complexity, ecosystem models typically simplify the systems they are studying to a limited number of components that are well understood, and deemed relevant to the problem that the model is intended to solve.
