红鹿（Cervus elaphus）雌性（母鹿）对Rhum的优势等级差异与其繁殖成功以及雄性和雌性后代的相对成功有关。男性（雄鹿）出生的母亲以上的中位数排名比母鹿更成功，而母鹿出生的下属比雄鹿更成功。优势母畜产犊的公母比显著高于从属母畜。由于母鹿的优势等级与成年体重和出生体重有关，这些结果表明，出生性别比可能受到雌性早期发育过程中环境因素的影响。
Differences in dominance rank among red deer (Cervus elaphus) females (hinds) on Rhum were related to their breeding success as well as to the comparative success of male and female offspring. Males (stags) born to mothers above median rank were more successful than hinds, while hinds born to subordinate mothers were more successful than stags. The ratio of male to female calves produced by dominant mothers was significantly higher than that produced by subordinates. Since dominance rank among hinds is related to their body weight as adults and to their birth weight, these results suggest that the birth sex ratio may be affected by environmental factors operating during a female''s early development.
