World Distribution

The present world distribution of six species of Cryptolestes found in stored produce is delineated from the evidence of specimens collected from a small number of countries and from specimens collected from produce examined in ships at British ports.It is concluded that C. ferrugineus (Steph.) is worldwide, being found in temperate and tropical areas and in humid and dry zones. The range of C. minutus (Ol.) is limited by low temperature and low humidity but it is more abundant than C. ferrugineus in the wet tropics. C. pusilloides (Steel & Howe) is at present confined to the southern hemisphere but may be spreading slowly. It seems unlikely that this species entered stored products handled by the shipping trade much before 1944. C. turcicus (Grouv.) has been identified from Europe, North and tropical Africa, Turkey, North America, Uruguay and Argentina, and C. spartii (Curt.) only from Europe, North Africa and Turkey. C. ugandae Steel & Howe is rare, being found only from Uganda, Nigeria and Ghana.

AbstractDust and processes of raindrop formation in the clouds play a very important role in the climatic evolution of tropical north Africa. Sedimentologic, stratigraphic, pedologic, geomorphologic, and palynologic data converge to show that a major environmental change occurred in tropical Africa about 7000 yr B.P. In the Sudanian and Sudano–Guinean zones (wet tropical zone), from 15,000 to 7000 yr B.P., rivers deposited mostly clay, while from 7000 to 4000 yr B.P. they deposited mostly sand. During the first period, pedogenesis was vertisolic (montmorillonite dominant), associated with pollen belonging mostly to vegetation typical of hydromorphic soils, while during the second period pedogenesis was of ferruginous type (kaolinite dominant) with pollen belonging mostly to vegetation typical of well-drained soils. The great change near 7000 yr B.P. is linked chiefly to a major hydrological change that appears related to a change in the size of raindrops: from fine rains associated with considerable atmospheric dust (raindrop diameter essentially less than 2 mm) to the second period associated with thunderstorm rains (raindrop diameter mostly greater than 2 mm). The size of raindrops is related particularly to cloud thickness and dust concentration in the troposphere. Thunderstorm activity is influenced also by fluctuations of the atmospheric electricity, modulated by the sun.

Insight Into

The two versions of the autobiography that Nicholas Said published offer insight into 19th-century conditions in five continents as well as insight into life as a child, slave, manservant, and teacher. As a child in the 1830s, Said was enslaved in Borno, marched across the Sahara Desert, and passed from hand to hand in North Africa and the Middle East. After serving as a slave in various societies, Said was freed by a Russian aristocrat in the late 1850s after accompanying the aristocrat in question to various parts of Europe. In the 1850s, Said also traveled as a manservant for a European traveler to South and North America. Ultimately he settled in the United States, where he authored two versions of his autobiography, served as a teacher and soldier, got married, and disappeared from sight. This article compares the two versions of the autobiography that Said published, provides an overview of Said’s life, charts the development of scholarly works on Said, and draws attention to the primary sources related to the study of Said and his autobiography.

And Function

The genus Iris consists of approximately 360 species and is distributed to Eurasia, North Africa, and North America. Belamcanda chinensis was incorporated into the genus Iris by APG III as Iris domestica. Iris species have also been cultivated as ornamentals since ancient times. Many flavonoids are isolated and identified from the flowers, leaves, and rhizomes. So far as we know, 6 anthocyanidins, 13 flavones, 20 flavonols, 20 C-glycosylflavones, 14 flavanones, 11 dihydroflavonols, 6 flavan and proanthocyanidins, and 85 isoflavonoids were reported as aglycones and glycosides. However, chalcones, dihydrochalcones, aurones, biflavonoids, and neoflavonoids are not found in the genus Iris. Fifteen xanthones that are related to flavonoids were also isolated from Iris species. In this review, we describe the flavonoids and xanthones that were isolated and characterized from Iris species. Moreover, their phytochemistry, contribution to the flower colors, relationships with taxonomy, and activities and functions are also discussed.

The Albian-Cenomanian (Lower Cretaceous-Upper Cretaceous) boundary in Texas and northern Mexico

As first designated by Böse, the Albian-Cenomanian (Lower Cretaceous-Upper Cretaceous) boundary in northern Mexico and Texas is selected at the base of the ammonite zone ofPlesioturrilites brazoensis(Römer). This boundary seems to best agree with boundaries selected for North Africa and Europe, but in North America it may not be the optimum boundary for paleontologists working with foraminiferans.
