我们调查了家庭成员的信息是如何编码的个别特定的肛门腺分泌（AGS）的海狸，加拿大蓖麻。由于海狸生活在严格的家庭单位和亲属共享更多的功能在AGS配置文件比非亲属，家庭成员共享更多的AGS功能比非家庭成员。因此，家庭承认似乎是一个自然的结果，更具体的亲属承认。多变量统计分析揭示了使用多组分AGS编码家族成员的两种可能性：使用两种（女性）至三种（男性）AGS化合物或多种化合物，但我们无法确定哪种可能性更大。化合物在编码家族成员信息方面并不同等重要，并且化合物之间的相互作用复杂。我们尝试用两个、三个或多个化合物重建不同科之间的谱系树。我们发现，无论是男性还是女性，使用少量或大量化合物构建的树没有显着差异。然而，从雄性化合物和雌性化合物衍生的树缺乏良好的一致性。
We investigated how information about family membership is coded by the individually specific anal gland secretion (AGS) in the beaver,Castor canadensis. Because beavers live in strict family units and relatives share more features in the AGS profile than non-relatives, family members share more AGS features than non-family members. Therefore, family recognition seems to be a natural consequence of the more specific kin recognition. Multivariate statistical analyses revealed two possibilities in coding for family membership using the multi-component AGS: either two (female) to three (male) AGS compounds or many compounds were used, but we were not able to determine which possibility is more likely. Compounds were not equally important in coding family membership information, and the interactions among compounds were complex. We attempted to reconstruct a lineage tree for the relationship among different families using two–three or many compounds. We found there was no significant difference for trees constructed by using few or many compounds in either males or females. However, the trees derived from male compounds and female compounds lacked good congruence.
