An ecosystem services conceptual diagram—also known as a causal chain, conceptual model, logic model, path model, or means-ends diagram—links changes caused by an external stressor or intervention through the ecological system to socio …

An ecosystem model can be very simple or very complex depending on the questions being examined. For example, a graphical model like the one below can be very useful to help us figure out what the various components are in an ecosystem and how they are related, but they are not very useful in predicting future conditions.

Ecosystem models attempt to incorporate ecosystem components (for example, populations, species, functional groups) and processes (for example, predator–prey interactions, large and small perturba-tions, dispersal) into one modelling framework.

These conceptual models link changes in biophysical systems (like a wetland) caused by an intervention (like a stream reconnection) to changes in socio-economic and human well-being outcomes (like property damage and injury due to flooding) and can also include direct, not environmentally mediated, changes in human well-being (like restoration j...

This document includes materials for workshops to help a U.S. Forest Service planning team identify key ecosystem service management outcomes and develop socioeconomic metrics for those outcomes using ecosystem service conceptual models (ESCMs). These materials were adapted from virtual workshops held in summer 2020 with the Ashley National Forest.

2024年4月15日 · The diagram of ecosystem represents various components of an ecosystem that form complex, dynamic networks of living beings interacting with their surroundings and one another. "Eco" stands for environment, and "system" for related components or activities in the word "ecosystem."

2012年10月31日 · To make an ecosystem (diagram/ model) showing how an ecosystem works. It must contain at least three types of each of the following: abiotic elements, plants, herbivores, carnivores, and omnivores. Organism numbers must have the necessary resources in the ecosystem to maintain its carrying capacity.

We model or describe an ecosystem as a set of pools or compartments, connected by fluxes, that is, transfers of energy or materials among pools. Figure 2.2: An ecosystem perspective of lake, in terms of phosphorus (Carpenter et al. 1992).

To test this, the “Daisyworld” model is used to simulate the effects of diversity and trophic complexity increments on ecosystem stability. For this, the model was consecutively run with: 1st...

We created an interactive, expandable tree diagram of PEWI’s science model for users to explore the components of all seven science modules. By navigating to the science model webpage, you can click on any node to expand the model out to increasing levels of detail.
