The European rabbit (Oryctolagus cuniculus) uses the secretion of the chin gland to maintain dominance hierarchies in the wild. Recent work has investigated changes in the secretion when social status is manipulated in the rabbit. When a rabbit becomes dominant, a new compound appears in his secretion, 2-phenoxyethanol. This compound is used as a fixative in the perfume industry. This study investigates whether the compound performs a similar function in the secretion of the rabbit. 2-Phenoxyethanol is not detected olfactorially by rabbits, and slows the release rate of some of the compounds that occur naturally in rabbit chin gland secretion. We suggest that when a rabbit becomes dominant, he adds a fixative to his secretion so that his scent will persist in the environment and not dissipate. He will thus come to dominate the olfactory environment, in much the same way as he does the physical environment.

欧洲兔子 (Oryctolagus cuniculus) 在野外使用下巴腺的分泌物来维持优势等级。最近的工作研究了在兔子中操纵社会地位时分泌物的变化。当兔子占主导地位时,他的分泌物中会出现一种新的化合物2-苯氧乙醇。该化合物在香料工业中用作固定剂。这项研究调查了该化合物在兔子的分泌中是否具有相似的功能。2-苯氧乙醇在兔子的嗅觉上没有检测到,并且减慢了兔子下巴腺分泌中天然存在的某些化合物的释放速率。我们建议,当兔子占主导地位时,他会在分泌物中添加固定剂,以使其气味在环境中持续存在而不会消散。因此,他将以与物理环境几乎相同的方式来统治嗅觉环境。
