A survey of the Easter Island landscape has resulted in the recognition of numerous lithic mulched household gardens and fields. It is proposed that lithic mulching was a technological innovation introduced to enhance the moisture retention capacity of the excessively drained island soils, and was an innovation incorporated into elite managed field systems which arose in the early 15th century to meet the demands for surplus production. Key-words: Easter Island, agriculture, field-systems, social hierarchy, Polynesia, environment, Introduction Traditional Pacific island societies are fundamentally agricultural populations and their production systems have been the focus of extensive ethnographic research (e.g. Barrau 1961; 1965; Brookfield 1972; Kirch 1990; 1994; [...]

We report recent X-ray Fluorescence analysis of samples from neighboring basalt adze production locales situated in western Tutuila, American Samoa. These data allow for the successful reassignment of source locations to locally and regionally transferred adzes with greater precision, and highlights the relevance of intra-island source analysis when addressing inter-archipelagic exchange models.

We tested the sensitivity of the Aplysia activity rhythm to red light in three ways: first, by measuring the response of the rhythm to 24 h cycles of red light (RD), second, by measuring the effect of constant red background light (RR) on the rhythm driven by superimposed white LD, third, by measuring the effect of RR on freerunning. In several experiments we removed the eyes in order to assess their role in mediating the action of red light. Results for individuals and groups were analyzed by calculating form estimates and periodograms. These results show that Aplysia have photoreceptors outside the eyes that are sensitive to red light and that are coupled to locomotion. It is unlikely that the eyes themselves are red sensitive photoreceptors that can reflexively drive locomotion in red lightcycles. On the other hand, it is quite likely that the eyes are a part of a circadian pacemaking system that can be entrained by extraocular red sensitive photoreceptors. We have drawn a hypothetical flow diagram that relates the known facts about circadian organization in Aplysia (Fig. 8). In the diagram rhythmic behavior arises from the convergence and integration of temporal information from several classes of photoreceptors. Internally timed signals from the eyes both facilitate locomotion and uncouple locomotion from extraocular mechanisms. [ABSTRACT FROM AUTHOR]
