Abstract
The general aim of this article is to carry out a reconstruction of the theory of Population Dynamics
(DP) in Ecology, according to Castle’s (2001) general stance with regard to the semantic view of
theories, but doing it within the framework of metatheoretical structuralism. Thus, we will first identify
Population Dynamics’ basic theory-element: its core K(DP) – with the class of potential models, the
class of models (through the identification of its fundamental law) and the class of partial potential
models (though leaving aside the identification of its constraints and its intertheoretical links) –,
and its domain of intended applications I(DP). Then, we will establish the general guiding lines of its
theory-net, developing in some detail one of its main lines of specialization – namely, that related to
the so-called “continuous growing” of the considered populations –, with DP’s principal “models”, and
leave developing of the other of its main lines of specialization – namely, that related to the so-called
“discrete growing” of the considered populations – for a further publication.
