合作育种策略导致短期的直接健身损失时，个人丧失或分享繁殖。合作策略的直接健身效益往往是延迟的，难以量化，需要终生繁殖的数据。在这里，我们使用一个纵向数据集来研究橡子啄木鸟（Melanerpes formicivorus）的合作一夫多妻制的终身生殖成功，它作为孤对筑巢或与同性共育者共享生殖。我们发现，男性和女性生产的年轻人每次成功的筑巢尝试时，共享生殖。然而，雄性筑巢在二人组和三人组有更长的生殖寿命，更多的终身筑巢尝试和更高的终身生殖成功比那些单独繁殖。对于女性来说，二人组的共同繁殖增加了生殖寿命，因此在二人组中筑巢的女性的一生生殖成功率与单独筑巢的女性相当，并且高于三人组中筑巢的女性。这些结果表明，对于男性二人组和三人组，生殖成功本身可能提供足够的健身效益来解释合作一夫多妻制的存在，以及在女性中作为二人组的共同繁殖的好处高于以前的假设。终身个人健康数据对于揭示合作一夫多妻制的全部成本和收益至关重要。
Cooperative breeding strategies lead to short-term direct fitness losses when individuals forfeit or share reproduction. The direct fitness benefits of cooperative strategies are often delayed and difficult to quantify, requiring data on lifetime reproduction. Here, we use a longitudinal dataset to examine the lifetime reproductive success of cooperative polygamy in acorn woodpeckers (Melanerpes formicivorus), which nest as lone pairs or share reproduction with same-sex cobreeders. We found that males and females produced fewer young per successful nesting attempt when sharing reproduction. However, males nesting in duos and trios had longer reproductive lifespans, more lifetime nesting attempts and higher lifetime reproductive success than those breeding alone. For females, cobreeding in duos increased reproductive lifespan so the lifetime reproductive success of females nesting in duos was comparable to those nesting alone and higher than those nesting in trios. These results suggest that for male duos and trios, reproductive success alone may provide sufficient fitness benefits to explain the presence of cooperative polygamy, and the benefits of cobreeding as a duo in females are higher than previously assumed. Lifetime individual fitness data are crucial to reveal the full costs and benefits of cooperative polygamy.
