Highlights Shell tool residues (starch) inform on timing of five crop introductions to Marquesas Islands. Four of west Pacific origin (kava, yam, breadfruit, taro) and one South American (sweet potato). The economic importance of sweet potato possibly has been under-estimated. Residues also reveal unexpected uses of shell tools.

The chemical diversity associated with marine natural products (MNP) is unanimously acknowledged as the “blue gold” in the urgent quest for new drugs. Consequently, a significant increase in the discovery of MNP published in the literature has been observed in the past decades, particularly from marine invertebrates. However, it remains unclear whether target metabolites originate from the.

From the three edges of its base arise three prominent straight radial ribs, which are prolonged into three large divergent feet, of.

Recently A. Chavan (1937, 1938) has published a valuable essay on the classification of the Lucinidae. Although the writer does not accept all the conclusions concerning New Zealand groups, he would like here to record his appreciation of M. Chavan's work. Many more of such family revisions are needed by workers in Mollusca. Gonimyrtea Marwick.

Star-shaped forams, Calcarina sp., on an algal substrate. Photo from here. About a month ago, I presented my first post on the marine shell-bearing protists known as foraminiferans.That post was on forams that constructed their shell by gluing together sand but I mentioned that there were other families that secreted their shells themselves.

A lead proponent of the importance of the protoconch in 'turrid' taxonomy was the New Zealand malacologist A. W. B. Powell who produced an influentiall classification of turrids between the 1940s and 1960s. Nevertheless, Powell did note an interesting phenomenon: the common existence of 'genus pairs' that were all but indistinguishable in.

This essay reviews the context and the content of the reform initiative, the preliminary outcomes and many challenges faced in its implementation, and the lessons for other developing countries aiming to support community-based management in fisheries or other natural resource sectors.

All the isolates were inhibited to varying degrees by Alteromonas sp. in vitro. The antibacterial substance produced by the Alteromonas sp. was soluble in organic solvent and closely bound to the external surface of bacterial cells.

Posts about test 2 written by cambriaromance. Populations of H. erectus were the first human emigrants from Africa. Traveling a route that must have been much the same as that hypothesized for moderns, Lecture 6, they reached the islands of Indonesia (review the map in lecture 5) where fossil crania have been found at Trinil, Ngandong, Sangiran, and Perning near the city of Mojokerto.
