[{"abstract":[{"text":"<jats:p> This paper proposes a review focused on exotic chemotaxis and cross-diffusion models in complex environments. The term exotic is used to denote the dynamics of models interacting with a time-evolving external system and, specifically, models derived with the aim of describing the dynamics of living systems. The presentation first, considers the derivation of phenomenological models of chemotaxis and cross-diffusion models with particular attention on nonlinear characteristics. Then, a variety of exotic models is presented with some hints toward the derivation of new models, by accounting for a critical analysis looking ahead to perspectives. The second part of the paper is devoted to a survey of analytical problems concerning the application of models to the study of real world dynamics. Finally, the focus shifts to research perspectives within the framework of a multiscale vision, where different paths are examined to move from the dynamics at the microscopic scale to collective behaviors at the macroscopic scale. </jats:p>","lang":"eng"}],"status":"public","type":"journal_article","publication":"Mathematical Models and Methods in Applied Sciences","language":[{"iso":"eng"}],"_id":"63290","user_id":"31496","year":"2022","citation":{"apa":"Bellomo, N., Outada, N., Soler, J., Tao, Y., &#38; Winkler, M.
