The ancient Greek word oikos (ancient Greek: οἶκος, plural: οἶκοι; English prefix: eco- for ecology and economics) refers to three related but distinct concepts: the family, the family's property, and the house. Its meaning shifts even within texts, which can lead to confusion.
The oikos was the basic unit of society in most Greek city-states. In normal Attic usage the oikos, in the context of families, referred to a line of descent from father to son from generation to generation. Alternatively, as Aristotle used it in his Politics, the term was sometimes used to refer to everybody living in a given house. Thus, the head of the oikos, along with his immediate family and his slaves, would all be encompassed. Large oikoi also had farms that were usually tended by the slaves, which were also the basic agricultural unit of the ancient economy.
Traditional interpretations of the layout of the oikos in Classical Athens have divided into men's and women's spaces, with an area known as the gynaikon or gynaikonitis associated with women's activities such as cooking and textiles work, and an area restricted to men called the andron. In Lysias' speech On the Murder of Eratosthenes, the women's rooms were said to be situated above the men's quarters, while in Xenophon the women's and men's quarters are next to one another.
Oikos is a monthly peer-reviewed scientific journal covering research in the field of ecology. It is published by Wiley-Blackwell on behalf of the Nordic Foundation Oikos. Since 2011, the editor-in-chief is Dries Bonte (Ghent University).
The journal was established in 1949 as Acta Oecologica Scandinavica, together with the Nordic Foundation Oikos, to provide a vehicle for publishing in the growing field of ecology. The journal content would have no preference with regard to taxonomic group. In the 1970s the scope was narrowed to studies with relevance to the progress of theory in ecology.
From 1949 to 1977, the journal appeared in one volume of three issues per year. From 1977 to 1987, two volumes per year were produced, and three volumes from 1987. In addition, from 1949–1975, a number of supplements were published at irregular intervals.
Since 2007, the Oikos subject editors make nominations for the annual Per Brinck Oikos Award given to a world-leading ecologist.
