mafia hypothesis
固有名詞
(biology)
A
hypothesis
attempting
to
explain
why
most
hosts
of
brood
parasites
care
for
the
parasite's
nestlings.
Since
the
host's
nest
is
attacked
if
the
parasite's
egg
is
detected
and
rejected,
this
indirectly
enhances
selective
pressures
favouring
aggressive
parasite
behaviour
that
may
result
in
positive
feedback
between
mafia-like
parasites
and
compliant
hosts.
日本語の意味
生物学における「マフィア仮説」とは、寄生巣を持つ動物が、寄生鳥の卵を検知して拒否すると巣が攻撃されるため、結果的に寄生鳥の攻撃的な行動が選択圧として働き、これが寄生者と従順な宿主との間で正のフィードバックループを引き起こすという現象を説明する仮説を指します。
