During the past few months the writer conducted observations to determine, first, if Aëdes aegypti preferred places of oviposition within habitations or those located outside with natural shelter near by, and, second, the distance from human habitations at which this species may breed. These investigations were carried out in, or near, the compound of the West African Yellow Fever Commission at Yaba, near Lagos, Nigeria.

Relationships of Ixonanthaceae and Irvingiaceae have been poorly known in the past. We therefore investigate the relationships of these families here. Plastid atpB, rbcL and ndhF sequences from taxa representing all genera were analysed using maximum likelihood. Allantospermum was found as sister to Irvingiaceae and does not belong to Ixonanthaceae where it was often traditionally placed. This position of Allantospermum in Irvingiaceae is further supported by numerous putative synapomorphic characters. Expanded species sampling in Ixonanthaceae found that African Phyllocosmus was embedded within a strongly supported clade containing American Ochthocosmus. A re-evaluation of morphological characters of the two supports an enlarged concept of Ochthocosmus. Within Irvingiaceae, the West African monotypic Desbordesia was embedded within a strongly supported clade of Old World Irvingia. These findings change circumscriptions of both Ixonanthaceae and Irvingiaceae.

Islamic Civilization

IntroductionHuman development, from the Islamic point of view, can be achieved onlyby following the footsteps of the Prophet (SAAS). The nearer one comes toimbibing the Message of the Quran, Sunnah, and Shari’ah in one’s life, themore humanly developed one becomes, because personal development in Islamis measured by one’s refinement in living this Message. The more refinedand developed are the persons in a community, the better will be their cultureand civilization.As long as Muslims continued moulding their life according to the Shari‘ah,their civilization in Medina, Baghdad, Andullis, Constantinople, and Delhiflourished. The decline and fall of Islamic civilization came when Muslimsstarted paying mere lip service to the formula of faith and departing fromthe spirit and purposes of the Shari‘ah. This was the unfortunate phenomenonthroughout the Muslim world. Fortunately, the rightly inspired people roseto bring back the erring Muslims to the path of the Shari’ah. This paper seeksto present an assessment of the dynamics used by a Mujaddid (a promoterof Tajdid or revival) of West Africa to re-Islamize a society that had sunkinto the abyss of confusion.Islam in West AfricaWest Africa, situated south of the Sahara desert, and which the Arabhistorians called Bilad al Sudan, has witnessed in the past, many Islamicempires, e.g., Ghana, Mali, Songhai, and Bornu, the last of which was theSokoto Caliphate. It emerged from the process of Tajdid (renewal or revival inaccordance with the Quran and Sunnah)’ which was started by Shehu(Shaikh) ‘Uthman Danfodio (1754-1817) in 1774, and which culminated in ...

Abstract The Arabic manuscripts of Timbuktu have received considerable publicity during the past 25 years, yet their contents remain largely unknown. Since 2012, an inventory of nearly 350,000 Timbuktu manuscripts in private libraries has been underway, and the contents of those libraries are now accessible in the West African Arabic Manuscript Database (WAAMD). This analysis examines 31 of the 35 libraries and in addition to reporting on their contents, notes challenges in accessing incompletely identified works, and compares the manuscripts with other West African collections.

Sub-Saharan West Africa has remained largely a blank space on the world rock-art map, in spite of a steady trickle of reports during the past century on pictograph and petroglyph sites in the West African sahel and savanna belts. It seems that the nature of the rock art reported, predominantly ‘geometric’ and saurian motifs, and ‘stick figures’, as well as its apparent recent age, formed little incentive for in-depth studies of rock art in this region. From sub-Saharan Mali, for example, only two sites have been published to a satisfactory standard (Huysecom 1990; Huysecom et al. 1996). The richness of the region in rock art, as indicated by several authors (e.g. Griaule 1938; Huysecom & Mayor 1991/92; Togola et al. 1995), has been confirmed by on-going research on rock art in the Boucle du Baoulé region (map, FIGURE 5) in the southwest of the country (Kleinitz 2000). In three field seasons, 14 known and 38 newly identified rock-shelters and open-air sites with pictographs and peboglyphs have been recorded.

A survey of the distribution of Aëdes aegypti and other Culicine mosquitos was made during the dry season of 1942, between 31st March and 15th May. The position of Eritrea gives it a particular interest in relation to the possible spread of yellow fever from Africa to the East. In the west it borders on the Anglo-Egyptian Sudan, in parts of which yellow fever is endemic, and it has a Red Sea coast line of some 600 miles, near the centre of which is the port of Massawa. The Culicines hitherto found include six that are known to be potential vectors of yellow fever.The topography and climate of Eritrea have been described by Lega, Raffaele and Canalis (1937). The country may be divided into four areas, the eastern and western plains, the mountain slopes and the plateau. The latter, on which lie several of the towns, is from about 1,900 to 2,500 metres (some 6,200 to 8,200 feet) above sea level.

Few English-speaking scholars realise that a francophone network of scholars has powerfully developed the study of contact between French and African languages over the past decade, and that this is currently being synthesised in the form of an Inventaire des particularités lexicales du français en Afrique noire. This corporate work, sponsored by the Association des universités partiellement ou entièrement de langue française (A.U.P.E.L.F.) and the Agence de coopération culturelle et technique (A.C.C.T.),1 is of considerable linguistic, educational, and sociopolitical significance, and deserves to be widely known in Africa. Indeed, it will be remembered that at the founding of the West African Linguistic Society in 1961 two surveys were mooted: West African languages and, later, English in West Africa, of which the former was accomplished with the help of the International African Institute and the Ford Foundation, while the latter was forgotten. With the ‘Inventory of French in Africa’, the francophone network of scholars has certainly stolen a march on English-speaking Africa.

The past few decades have seen the emergence of several worldwide arbovirus epidemics (chikungunya, Zika), the expansion or recrudescence of historical arboviruses (dengue, yellow fever), and the modification of the distribution area of major vector mosquitoes such as Aedes aegypti and Ae. albopictus, raising questions about the risk of appearance of new vectors and new epidemics. In this opinion piece, we review the factors that led to the emergence of yellow fever in the Americas, define the conditions for a mosquito to become a vector, analyse the recent example of the new status of Aedes albopictus from neglected mosquito to major vector, and propose some scenarios for the future.
