摘要:Generally, the study of animal welfare is based on the identification and promotion of speciestypical behaviors of the individual or target group. The adjustment to new conditions (i.e. captivity) is easier for some species, while for others it may be very difficult or even impossible. The adjustment to captive conditions is a basic element for the development of conservation strategies (i.e. translocation, introduction, and reintroduction) and can be measured by different variables related to an animal’s psychological well-being. From a psychological point of view, we assume that organisms can adjust their behavior in correspondence to changes in their environment, adjustment that is enabled by an ecological contact medium (e.g. Ribes, 2007; Ribes & Perez-Almonacid, 2011). Under this assumption, we propose a methodology that allows the classification, identification and manipulation of relevant factors for an individual’s adjustment to different conditions (i.e. freedom and captivity) and a more rational handling of organisms and their specific life condition. The main elements of this methodology are: 1) adaptive and survival circumstances; 2) description of ecological milieu; 3) interactive processes (i.e. intra-individual, inter-individual, and inter-individual dependence); and 4) interaction-situation relationship.
