交配偏好和交配前生殖隔离的研究往往集中在女性，但男性偏好的潜在重要性越来越受到重视。我们调查男性行为的背景下，生殖隔离的分歧溯河产卵和流居民人口的threespine棘鱼，Gasterosteus aculeatus，使用大小操纵的女性两种生态型。具体来说，我们问男性求偶偏好是否存在，以及它们是否基于相对体型，非体型方面的生态型或其他特征。因为男性行为是相互关联的，我们对相关性进行了主成分分析，并对主成分进行了后续分析。这两个男性生态型不同的整体行为频率，流居民男性表现出一贯更有力和积极的求爱比溯河产卵男性，否则积极的行为发挥更积极的作用，溯河产卵比流居民求爱。我们观察到更有力的求爱向较小的女性（相对较小）流居民男性和反向模式（相对较大）溯河产卵男性。因此，大小决定性的男性求爱偏好可能有助于生殖隔离在这个系统中，虽然偏好是绝对的。我们发现很少有迹象表明，男性优先响应女性自己的生态型独立的身体大小。
Studies of mating preferences and pre-mating reproductive isolation have often focused on females, but the potential importance of male preferences is increasingly appreciated. We investigated male behavior in the context of reproductive isolation between divergent anadromous and stream-resident populations of threespine stickleback, Gasterosteus aculeatus, using size-manipulated females of both ecotypes. Specifically, we asked if male courtship preferences are present, and if they are based on relative body size, non-size aspects of ecotype, or other traits. Because male behaviors were correlated with each other, we conducted a principal components analysis on the correlations and ran subsequent analyses on the principal components. The two male ecotypes differed in overall behavioral frequencies, with stream-resident males exhibiting consistently more vigorous and positive courtship than anadromous males, and an otherwise aggressive behavior playing a more positive role in anadromous than stream-resident courtship. We observed more vigorous courtship toward smaller females by (relatively small) stream-resident males and the reverse pattern for (relatively large) anadromous males. Thus size-assortative male courtship preferences may contribute to reproductive isolation in this system, although preferences are far from absolute. We found little indication of males responding preferentially to females of their own ecotype independent of body size.
