Defences against brood parasites from a social immunity perspective.

摘要: Parasitic interactions are so ubiquitous that all multicellular organisms have evolved a system of defences to reduce their costs, whether the parasites they encounter classic which feed on individual, or brood usurp parental care. Many parallels been drawn between deployed against both types parasite, but typically, while selected protect survival, those parent's inclusive fitness, suggesting selection pressures impose fundamentally different. However, there is another class specifically an individual's known as social immunity. Social immune responses include anti-parasite typically provided for others in kin-structured groups, such antifungal secretions produced by termite workers brood. Defences parasites, therefore, more closely aligned with responses. Much like immunity, host parasitism employed donor (a parent) benefit one recipients (typically kin), and therefore donor's not survival ultimately fitness individual This can lead severe conflicts different parties, whose interests always aligned. Here, we consider light at stages parasite encounter, addressing where occur how might be resolved. We finish considering this approach could help us address longstanding questions our understanding parasitism. article part theme issue 'The coevolutionary biology parasitism: from mechanism pattern'.
