At the risk of reiterating what is well-known, this thread would be incomplete without a mention of Richard MacNeish's classic diachronic, interdisciplinary study of a region in south-central Mexico: The Prehistory of the Tehuacan Valley (1967-1972). Volume 1 (of five) is dedicated to "Environment and subsistance." More recent research has added much information, but this massive contribution continues to be relevant for understanding the changing relationship of human populations to their environments.
On these studies, and MacNeish's contributions to research in other parts of the world, see: http://books.nap.edu/html/biomems/rmacneish.pdf
You are probably familiar with research in eastern North America, so at the risk of providing info you are already familiar with... The seeds of several weeds were collected and likely cultivated for some hundreds of years before the arrival of domesticated plants. In this case, "domesticated plants" refers to squash, beans and maize, and weedy plants include chenopodium, goosefoot, sumpweed and others, along with nuts, berries and other fruits. The debate about whether any of these weeds were domesticated, or to what degree they were domesticated, is ongoing, but there is very good evidence for extensive use of these weeds in prehistory.
Kristen Gremillion has a ResearchGate page that should provide all the basics for this region.
