We introduce in this paper a new interacting particle system intended to model an example of ecological succession involving two species: Pteridium aquilinum L. commonly called bracken and Fagus sylvatica L. or european beech. The species both compete over vacant sites, assimilated to windfall, according to fundamentally different evolutionary strategies. Our main objective is to exhibit phase ...

We present numerical results based on a simplified ecological system in evolution, showing features of extinction similar to that claimed for the biosystem on Earth. In the model each species consists of a population in interaction with the others, that reproduces and evolves in time. Each species is simultaneously a predator and a prey in a food chain. Mutations that change the interactions ar...

A representational approach to ecological psychology is presented. This paper identifies a computational-level commonality in ecological psychology research related to passability of apertures. It is argued that a cognitive mechanism capable of comparing the geometric properties of an environment and the geometric properties of the agent can be used to support judgments for action in space.

An alternative view of presence is introduced based on existential philosophy and ecological psychology. This view favors a Heideggerian/Gibsonian metaphysic over the more conventional rationalistic orientation. In this alternative view, notions of subjective presence and objective presence no longer exist. Presence is instead tied to one’s successfully supported action in the environment, this...

this study investigates the application of landscape ecology in planning and design of urban ecological systems. the ecological approach to landscape planning and the concepts of designing and implementing ecological systems have gained increasing attention in the last two decades. however, the ecological systems of urban environment need more research to consider built and natural patches and ...

environmental degradation model is one of the environmental impact assessment (eia) methods in which ecological cumulative effects of human activities on his surrounding nature could be evaluated and quantified. as a special trait of landscape ecological metrics is the ability of rapid assess and recognize of human activities in the shortest time. thus in this study, we used a landscape degrada...
