Abstract In the region lying between Salerno and the Ofanto river on the north and Cetraro and the gulf of Tarento on the south and southeast, the south end of the Apennines merges into the structural pattern of the western Mediterranean region (southwestern Italy-Sicily-North Africa). After a cycle of sedimentation, tectonic deformation, and erosion extending from Triassic to upper Oligocene, a second cycle began in the late Oligocene and earliest Miocene. Mosaic faulting, in general based upon major structural features of the earlier cycle, occurred throughout the entire southern Italy-North African region. The age of the quartzite flysch remains unknown but is probably Jurassic-Cretaceous.

Despite being one of the most charismatic elements of the Mediterranean Basin fauna and its threatened status, the western Mediterranean range of Testudo graeca is at present very poorly known. The present work provides the most detailed geographical and ecological description for the North African clade of T. graeca so far. We gathered 283 occurrence data of T. graeca in North Africa and modelled the distribution by means of presence-only distribution modelling tools. The obtained model was then projected to southern Europe in order to explore whether the environmental characteristics of European populations fall into the predicted niche of the species in North Africa. T. graeca showed a wide environmental range in North Africa. Presence localities ranged from the sea level to 2090 m of altitude and from 116 to 1093 mm of annual precipitation. The presence-only model indicates that distribution in North Africa is mainly related to rainfall, specifically rainfall values in the wettest and coldest quarter of the year. The distribution model showed a range of ca. 1 000 000 km2. The projection of the model to southern Europe showed that the southern Iberian and Balkan Peninsulas, as well as most Mediterranean islands, present climatic conditions within those found in the range of the species in North Africa.

AbstractWe investigated the mitochondrial phylogeography of spur-thighed tortoises (Testudo graeca) in the Western Mediterranean. In North Africa, four major lineages (A-D) occur that together constitute a well-supported clade corresponding to one of the six major clades within T. graeca; the North African clade is sister to a Caucasian clade representing the subspecies T. g. armeniaca. Phylogenetic relationships between the North African lineages are badly resolved. Lineage A is distributed in Tunisia and adjacent Algeria, lineage B in Algeria and northern Morocco, lineage C in the Libyan Cyrenaica Peninsula, and lineage D north of the High Atlas Mts. and in the Souss Valley (southern Morocco). Lineage B is subdivided into two subgroups, B1 (eastern Morocco and Algeria) and B2 (north-western Morocco). Italian tortoises harbour haplotypes of lineage A, Spanish tortoises of subgroup B1. Based on a relaxed molecular clock calibrated with fossil evidence, the six major mtDNA clades of T. graeca are estimated to have diverged approximately 4.2-1.8 Ma ago; the split between the clades representing the eastern subspecies T. g. ibera and T. g. terrestris is younger than the split between Western Mediterranean tortoises and T. g. armeniaca. The Western Mediterranean lineages A-D were dated to have diverged at least 1.4-1.1 Ma ago; B1 and B2 split approximately 0.7 Ma ago. Our results suggest that Italian and Spanish tortoises were either introduced or originated from trans-oceanic dispersal in historic or prehistoric times. Spur-thighed tortoises invaded North Africa probably across Near Eastern landbridges that emerged in the Late Tertiary. Their diversification in North Africa seems to be correlated with habitat aridization cycles during the Pleistocene. The ranges of the Western Mediterranean lineages largely correspond to the distribution of morphologically defined subspecies in North Africa, with exception of T. g. graeca and T. g. whitei, and of T. g. lamberti and T. g. marokkensis, which are not differentiated. We propose to lump the first two subspecies under the name of T. g. graeca and the latter under the name of T. g. marokkensis. The complex differentiation of spur-thighed tortoises in North Africa implies that the model of a bipartite east-west differentiation, as proposed for other Maghrebian amphibians and reptiles, may be too simplistic, reflecting incomplete locality sampling rather than actual phylogeographic differentiation.

Spain is more commonly known as Andalusia, the Andalusia comes from the word Vandalusia, which means the country of the Vandals, because the southern part of the Peninsula was once ruled by the Vandals before they were defeated by Western Gothia in the fifth century. This area was ruled by Islam after the rulers of The Umayyah seized the peninsula's land from the West Gothies during the time of the Caliph Al-Walid ibn Abdul Malik. Islam entered Spain (Cordoba) in 93 AH (711 AD) through the North African route under the leadership of Tariq bin Ziyad who led the Islamic army to conquer Andalusia. Before the conquest of Spain, Muslims had taken control of North Africa and made it one of the provinces from the Umayyad Dynasty. Full control of North Africa took place in the days of Caliph Abdul Malik (685-705 AD). Conquest of the North African region first defeated until becoming one of the provinces of the Umayyad Caliph spent 53 years, starting from 30 H (Muawiyah ibn Abi Sufyan's reign) to 83 H (al-Walid's period). Before being defeated and then ruled by Islam, in this region there were sacs which became the basis of the power of the Roman Empire, namely the Gothic Kingdom. In the process of conquering Spain there were three Islamic heroes who could be said to be the most effective in leading units of troops there. They are Tharif ibn Malik, Tariq ibn Ziyad, and Musa ibn Nushair. Subsequent territorial expansion emerged during the reign of Caliph Umar ibn Abdil Aziz in the year 99 AH/717 AD, with the aim of controlling the area around the Pyrenian mountains and South France. The second largest invasion of the Muslims, whose movement began at the beginning of the 8th century AD, has reached all of Spain and reached far to Central France and important parts of Italy. The victories achieved by Muslims appear so easy. It cannot be separated from the existence of external and internal factors. During the conquest of Spain by Muslims, the social, political and economic conditions of this country were in a sad state. Politically, the Spanish region was torn apart and divided into several small countries. At the same time, the Gothic rulers were intolerant of the religious beliefs adopted by the rulers, namely the Monophysites, especially those who adhered to other religions, Jews. Adherents of Judaism, the largest part of the Spanish population, were forced to be baptized to Christianity. Those who are unwilling brutally tortured and killed. The people are divided into the class system, so that the situation is filled with poverty, oppression, and the absence of equality. In such situations, the oppressed await the arrival of the liberator and the liberator was from Muslims. Warrior figures and Islamic soldiers who were involved in the conquest of Spain are strong figures, their soldiers are compact, united, and full of confidence. They are also capable, courageous, and resilient in facing every problem. Equally important are the teachings of Islam shown by the Islamic soldiers, like tolerance, brotherhood, and help each other. The attitude of tolerance of religion and brotherhood contained in the personalities of the Muslims caused the Spanish population to welcome the presence of Islam there. Since the first time Islam entered in the land of Spain until the collapse of the last Islamic empire was about seven and half centuries, Islam played a big role, both in fields of intellectual progress (philosophy, science, fiqh, music and art, language and literature) and the splendor of physical buildings (Cordova and Granada). The long history passed by Muslims in Spain can be divided into six periods. Spanish Muslims reached the peak of progress and glory rivaled the glory of the Abbasid sovereignty in Baghdad. Abdurrahman Al-Nasir founded the Cordova University. He preceded Al-Azhar Cairo and Baghdad Nizhamiyah.

Acephalic spermatozoa syndrome (ASS) is a rare but extremely severe type of teratozoospermia, defined by the presence of a majority of headless flagella and a minority of tail-less sperm heads in the ejaculate. Like the other severe monomorphic teratozoospermias, ASS has a strong genetic basis and is most often caused by bi-allelic variants in SUN5 (Sad1 and UNC84 domain-containing 5). Using whole exome sequencing (WES), we investigated a cohort of nine infertile subjects displaying ASS. These subjects were recruited in three centers located in France and Tunisia, but all originated from North Africa. Sperm from subjects carrying candidate genetic variants were subjected to immunofluorescence analysis and transmission electron microscopy. Moreover, fluorescent in situ hybridization (FISH) was performed on sperm nuclei to assess their chromosomal content. Variant filtering permitted us to identify the same SUN5 homozygous frameshift variant (c.211+1_211+2dup) in 7/9 individuals (78%). SUN5 encodes a protein localized on the posterior part of the nuclear envelope that is necessary for the attachment of the tail to the sperm head. Immunofluorescence assays performed on sperm cells from three mutated subjects revealed a total absence of SUN5, thus demonstrating the deleterious impact of the identified variant on protein expression. Transmission electron microscopy showed a conserved flagellar structure and a slightly decondensed chromatin. FISH did not highlight a higher rate of chromosome aneuploidy in spermatozoa from SUN5 patients compared to controls, indicating that intra-cytoplasmic sperm injection (ICSI) can be proposed for patients carrying the c.211+1_211+2dup variant. These results suggest that the identified SUN5 variant is the main cause of ASS in the North African population. Consequently, a simple and inexpensive genotyping of the 211+1_211+2dup variant could be beneficial for affected men of North African origin before resorting to more exhaustive genetic analyses.

High rates of desertion and surrender during the battles in North Africa in the summer of 1942 were a major factor in Eighth Army’s poor combat performance. At the time, some suggested that these problems were symptomatic of a lack of courage or even of cowardice. There are two broad strands to the conceptualization of courage and cowardice. One focuses on the willingness of the person to fight; the other puts emphasis on how actions express an individual’s ability to cope with fear. Whichever conceptualization is used, high morale motivates the soldier to fight and shields the ordinary recruit from his fear, preventing it from overcoming him in battle. Where morale fails, the soldier is left demotivated and burdened with his terror and, therefore, and is therefore prone to desertion or surrender. Because it is extremely difficult to maintain morale at a continuously high level in an environment governed by chance and managed by humans, all soldiers can find themselves in situations where their actions may be judged as cowardly. Alternatively, if they are properly motivated to fight and prepared by the state and military to deal with the unavoidable fear of combat, all soldiers can be labelled courageous. Accordingly, emotive terms should be avoided when attempting to describe rationally explainable outcomes. The undoubtedly negative connotations attached to cowardice in battle and the positive ones attached to courage are, therefore, arguably unhelpful in understanding Eighth Army’s performance in the summer of 1942 and the human dimension in warfare more generally.

Abstract This article aims at presenting ISIS expansion in North Africa in the first quarter of 2016, with its subsequent implication in the wider framework of Jihadist proliferation worldwide. It can be argued that, while losing real estate in the Middle East, ISIS has started a permanent search for extra-cellular matrices or an ongoing process of de- and reterritorialization. The allegiance and support pledged by other African-based terrorist groups or organizations such as Boko Haram, al-I’tisam of the Koran and Sunnah in Sudan, al-Huda Battalion in Maghreb of Islam, The Soldiers of the Caliphate, al-Ghurabaa, Djamaat Houmat ad-Da’wa as-Salafiya and al-Ansar Battalion in Algeria, Islamic Youth Shura Council, Islamic State Libya (Darnah), in Libya, Jamaat Ansar Bait al-Maqdis, Jund al-Khilafah and Mujahideen Shura Council in the Environs of Jerusalem in Egypt, Okba Ibn Nafaa Battalion, Mujahideen of Tunisia of Kairouan and Jund al-Khilafah in Tunisia and al-Shabaab Jubba Region Cell Bashir Abu Numan in Somalia is an alarming hypothesis of Jihadism reaching “the threshold of inevitability”- syntagm existent in the network theories of David Singh Grewal- turning a whole region, continent of even world into what Nassim Nicholas Taleb would call Extremistan.

Abstract We present for the first time the climatology of medium-scale traveling ionospheric disturbances (MSTIDs) by using Global Positioning System (GPS) receiver networks on geomagnetically quiet days (Kp ≤ 3) over the North African region during 2008-2016. The MSTIDs appear frequently as oscillating waves or wave-like structures in electron density induced by the passage of Atmospheric Gravity Waves (AGW) propagating through the neutral atmosphere and consequently, causing fluctuation in the ionospheric Total Electron Content (TEC). The TEC perturbations (dTEC) data are derived from dual frequency GPS-measurements. We have statistically analyzed the MSTIDs characteristics, occurrence rate, seasonal behavior as well as the interannual dependence. The results show a local and seasonal dependence of nighttime and daytime MSTIDs. The propagation direction is predominantly towards the South (equatorward), MSTIDs event period is (12 ≤ period ≤ 53 mins), and dominant amplitude (0.08 ≤ amp ≤ ~1.5 TECU), with a propagation velocity higher at daytime than nighttime. The amplitudes of the MSTIDs increase with solar activity. The local MSTIDs Spatio-temporal heat reveals variability in disturbance occurrence time, but seems to be dominant within the hours of (Northwest: 1200–1600 LT) and (Northeast: 1000–1400 LT) in December solstice during daytime, and around (NW: 2100–0200 LT) and (NE: 1900–0200 LT) in June solstice, but get extended to March equinox during solar maximum (2014) during the nighttime. The time series of MSTIDs regional distribution map is also generated. Atmospheric gravity waves (AGW) seems to be responsible for the daytime MSTIDs occurrence.

Typhoid fever is endemic in the Mediterranean North African countries (Morocco, Algeria, Tunisia, Libya, and Egypt) with an estimated incidence of 10-100 cases per 100,000 persons. Outbreaks caused by Salmonella enterica serovar Typhi are common and mainly due to the consumption of untreated or sewage-contaminated water. Salmonella enterica Paratyphi B is more commonly involved in nosocomial cases of enteric fever in North Africa than expected and leads to high mortality rates among infants with congenital anomalies. Prevalence among travellers returning from this region is low, with an estimate of less than one per 100,000. Although multidrug resistant strains of Salmonella Typhi and Paratyphi are prevalent in this region, the re-emergence of chloramphenicol- and ampicillin-susceptible strains has been observed. In order to better understand the epidemiology of enteric fever in the Mediterranean North African region, population-based studies are needed. These will assist the health authorities in the region in preventing and controlling this important disease.

Abstract This article discusses The Met’s unpublished Dalāʾil al-khayrāt—2017.301—(MS New York, TMMA 2017.301), together with a group of comparable manuscripts. The earliest known dated manuscript within the corpus, it introduces several iconographic elements that are new to the Dalāʾil, and which compare with the traditions developing in the Mashriq and the Ottoman world in particular. The article discusses Dalāʾil production in seventeenth-century North Africa and its development in the Ottoman provinces, Tunisia, and/or Algeria. The manuscripts illustrate how an Ottoman visual apparatus—among which the theme of the holy sanctuaries at Mecca and Medina, appearing for the first time in MS New York, TMMA 2017.301—is established for Muhammadan devotion in Maghribī Dalāʾils. The manuscripts belong to the broader historic, social, and artistic contexts of Ottoman North Africa. Our analysis captures the complex dynamics of Ottomanization of the North African provinces of the Ottoman Empire, remaining strongly rooted in their local traditions, while engaging with Ottoman visual idioms.

This chapter builds on the link between French colonial policies and Muslim–Jewish relations in the metropole by tracing how decolonization throughout North Africa changed the way a diverse set of social actors, including French colonial administrators, international Jewish spokesmen, and a wide range of indigenous nationalist groups conceptualized Jewish belonging throughout the region. It argues that the process led to the emergence of the “North African Jew,” a category to which no individual ascribed but that worked rhetorically to unite the diverse Moroccan, Tunisian, and Algerian Jewish populations into a collective often understood to be in conflict with “North Africans,” “Muslims,” or “Arabs.”
