After its theoretical analysis of the newly developed ecological approach to translation studies, this paper investigates the conditions, layers, goals, modalities and results (values) of interdisciplinary transplantation1 from ecology as the donor theory to translatology as the receptor in light of more general rules for interdisciplinary transplantation, with a view to discovering possible ways in which the ecological approach can further facilitate the advancement of translation studies. And then, by a brief analysis of the gains and losses of memetic studies in terms of interdisciplinarity, it goes on to discuss the theoretical isomorphism between natural science and social science. The importance of this discussion lies not just in its promise of further development of the ecological approach to translation studies but in its elicitation of the central issue of this paper: the relationship between interdisciplinary approaches and disciplinary integration of translatology
