Definition of Term

(English) Two-dimensional, multi-species, individual-based modeling platform, which focuses on fish and invertebrate species and their trophic interactions. The main characteristic of OSMOSE is that it assumes opportunistic predation based on spatial co-occurrence and size adequacy between a predator and its prey (i.e., size-based opportunistic predation). OSMOSE simulates the life cycle of (typically 10 to 20) "focal functional groups", and implicitly considers "biotic resources", which only serve as potential food source.
(French) Plate-forme de modélisation individu-centrée, multi-espèces et en deux dimensions, qui se concentre sur les espèces de poissons et d'invertébrés et leurs interactions trophiques. La caractéristique principale d'OSMOSE est qu'il part du principe que le processus de prédation est opportuniste et qu'il dépend de la co-occurrence spatiale des individus et de la taille des proies relativement à celle de leurs prédateurs (i.e., OSMOSE part du principe que la prédation est un processus opportuniste basé sur les tailles des individus). OSMOSE simule le cycle de vie de (typiquement 10 à 20) "groupes fonctionnels focaux", et considère de manière implicite des "ressources biotiques", qui servent simplement de nourriture potentielle aux groupes fonctionnels focaux.
