“…Thus, the coming years bring exciting opportunities for ecologists and evolutionary biologists to finally consider and accept oncobiota as a key player of the holobiont, and thus initiate and conduct theoretical and empirical research that adopts a very innovative perspective on the ecological and evolutionary importance of malignant cells. Using Tasmania devils and DFTD as a model system, Hamede et al (2020, This volume) discussed the relevance of cancer cells as selective agents and suggested a holistic framework to understand the interplay of ecological, epidemiological, and evolutionary dynamics of cancer in wildlife. Using a modeling approach, Perret, Gidoin, Ujvari, Thomas, and Roche (2020, This volume) explored, for the first time at the ecosystem level, the role of cancer in species interactions, notably host–predator interactions, and how in return, the outcome of alteredinterplay could affect the evolution of resistance mechanisms against cancer.…”
