Parabiosis, meaning "living beside", is a technical term in various contexts in fields of study related to ecology and physiology. It accordingly has been defined independently in at least three disciplines, namely experimental or medical physiology, the ecology of inactive physiological states, and the ecology of certain classes of social species that share nests. ==Etymology== Parabiosis derives most directly from new Latin,〔()〕 but the Latin in turn derives from two classical Greek roots. The first is ''παρά'' (''para'') for "beside" or "next to". In modern etymology this root appears in various senses such as "close to", "outside of", and "different". * In the physiological sense of "parabiosis", "para" apparently was intended to mean "next to". * In describing transiently inactive physiological states, "para" apparently meant "outside of". * In ecological usage the word was coined by the entomologist Auguste-Henri Forel as an analogue to "symbiosis", also in the sense of "next to". However, in this case the emphasis was in contrast to "together" ("sym-"). The second classical Greek root is ''βίος'' (''bios''), meaning "life". 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Parabiosis」の詳細全文を読む スポンサード リンク
