Résumé : Sometimes, in science, we get so obsessed with a particular piece of a puzzle, that we miss the big picture. The same seems to be happening in the study of interaction networks, with different schools arguing over pieces of reality. Aiming to take a step back and change our perspective, this presentation describes a novel cognitive model that provides an integrative solution to two classical dilemmas about interactions between organisms of different species. Our research team, in collaboration with other experts, embarked on an extensive investigation to uncover the underlying principles that could lead to this solution. Through a comprehensive analysis, first, we demonstrated the commonalities between the dilemmas, and employed a graphical model to better understand the theoretical connection between them. We then developed an algorithmic model that predicts the four most commonly observed network topologies in nature. Our cognitive model, initially designed for antagonisms in monolayer networks, was subjected to a series of empirical tests and logical deductions. The results show that the model can be extended to mutualisms and multilayer networks, highlighting its broad applicability. Currently, we are working to refine the model and develop it into a new semantic theory, which may have significant implications for basic and applied ecology. We invite the audience to join us as we share the journey of discovery, unveiling the exciting possibilities that this new theory presents.
