Ecosystems change at the Neolithic transition

The structures of the ecosystems in Central Sweden c. 7000 B.P. and 5000 B.P., i.e. on both sides of the Neolithic transition, are summarized. The difference between the systems is a difference in scale, not in structure. Both systems include culturally imposed clearance‐regeneration cycles. In the Early Neolithic ecosystem 100 times as much energy was converted to the use of man as in the Late Mesolithic system.

Preliminary report on the measurement of flakes from early post‐glacial settlements

A method of grouping early post‐glacial settlements is described. This is based upon Quaternary geological, archaeological and statistical methods. Hakes were measured from settlements dated ‐with a high degree of certainty through the agency of the natural sciences, and the results obtained were treated statistically.
