We hypothesize that biological diversification across ecological, spatial, and temporal scales maintains and regenerates the ecosystem services that provide critical inputs—such as maintenance of soil quality, nitrogen fixation, pollination, and pest control—to agriculture. Agrobiodiversity is sustained by diversified farming practices and it also supplies multiple ecosystem services to agricul...

One of the more intractable problems that archaeobiologists struggle with is how to characterise ancient subsistence systems when the plant and animal remains that we study are incommensurate in so many ways. Three examples from the upper Euphrates and Iran illustrate how changes in plant remains are associated with changes in animal exploitation. Two of them consider the agropastoral continuum...
