text: 'Brood parasites exploit their host in order to increase their own fitness.
Typically, this results in an arms race between parasite trickery and host defence.
Thus, it is puzzling to observe hosts that accept parasitism without any resistance.
The ‘mafia’ hypothesis suggests that these hosts accept parasitism to avoid retaliation.
Retaliation has been shown to evolve when the hosts condition their response to
mafia parasites, who use depredation as a targeted response to rejection. However,
it is unclear if acceptance would also emerge when ‘farming’ parasites are present
in the population. Farming parasites use depredation to synchronize the timing
with the host, destroying mature clutches to force the host to re-nest. Herein,
we develop an evolutionary model to analyse the interaction between depredatory
parasites and their hosts. We show that coevolutionary cycles between farmers
and mafia can still induce host acceptance of brood parasites. However, this equilibrium
is unstable and in the long-run the dynamics of this host–parasite interaction
exhibits strong oscillations: when farmers are the majority, accepters conditional
to mafia (the host will reject first and only accept after retaliation by the
parasite) have a higher fitness than unconditional accepters (the host always
accepts parasitism). This leads to an increase in mafia parasites’ fitness and
in turn induce an optimal environment for accepter hosts.'
