Both, non-reciprocity and mass conservation, have far reaching generic consequences for the universal dynamical behaviour of the concerned wide range of non-equilibrium systems. Results of many particular approaches to the mathematical modelling of such systems have shown that classical concepts of nonlinear and statistical physics, such as phase transitions, need to be reconsidered and developed further.
