ECOLANG - Communications Language for Ecological Simulations Network
António Manuel Correia PereiraThe document describes the communication language used in one multi-agent systems environment for ecological simulations, based on the EcoDynamo simulator application linked with several intelligent agents and visualisation applications and extends the initial definition of the language. The agents’ actions and perceptions are translated into messages exchanged with the simulator application and other age...
Management oriented mathematical modelling of Ria Formosa (South Portugal)
P. Duarte; B. Azevedo; C. Ribeiro; António Manuel Correia Pereira; M. Falcão; D. Serpa; R. Bandeira; J. Reia1 - Ria Formosa is a large (c.a. 100 km2) mesotidal lagoon system included in a Natural Park, with large intertidal areas and several uses such as fisheries, aquaculture, tourism and nature conservation. Its watersheds cover an area of approximately 864 km2, with a hydrographic network of small and, mostly, ephemeral rivers. 2 - The Soil and Water Assessment Tool (SWAT model) has been applied to the catchments ...
Different modelling tools of aquatic ecosystems : a proposal for a unified appr...
António Manuel Correia Pereira; Pedro Duarte; Alain NorroOver the last few decades, several modelling tools have been developed for the simulation of hydrodynamic and biogeochemical processes in aquatic ecosystems. Until late 70’s, coupling hydrodynamic models to biogeochemical models was not common and today, problems linked to the different scales of interest remain. The time scale of hydrodynamic phenomena in coastal zone (minutes to hours) is much lower tha...
How does estimation of environmental carrying capacity for bivalve culture depe...
Pedro Duarte; A. J. S. Hawkins; António Manuel Correia PereiraThe simplest computational approach for estimating environmental carrying capacity (CC) for bivalve suspension-feeders is to compare the combined rate of filtration with rates of processes that contribute to food renewal. More realistic approaches are based on mathematical models that take into account complex sets of feedbacks, both positive and negative, whereby cultured organisms interact with ecosystem proc...
