Symbiosis Evolution of Science Communication Ecosystem Based on Social Media: A Lotka–Volterra Model-Based Simulation

Table 1

The value range of the symbiosis coefficient and its corresponding symbiosis pattern. represents the influence coefficient of the scale change of population 2 on the growth of population 1.

Value range	Symbiosis pattern	Feature
	Not symbiosis	Two symbiotic units developed independently
	Not symbiosis	Two symbiotic units compete maliciously
or	Parasitic	Two types of symbiotic units, one reduced () and the other benefited ()
or	Commensalism	Two types of symbiotic units, one that benefits () and the other that does not affect ()
	Mutualism	Asymmetric mutualism between two types of symbiotic units (); symmetric mutualism between two types of symbiotic units ()
