AbstractWhile the Neogene history of the Eastern Mediterranean region is now fairly well understood, our knowledge of older regional palaeogeographies is less accurate, especially the positions of blocks and nappes constituting the Aegean Islands prior to the Cenozoic. Our study focuses on the ophiolite exposed on the island of Karpathos (Dodecanese), which is located in the Aegean fore-arc at a pivotal position between the ‘western’ and ‘eastern’ ophiolites of the Mediterranean region and where conflicting Late Jurassic and Late Cretaceous ages have led to diverging tectonic and palaeogeographic interpretations. To test these ages, we targeted the radiolarian cherts that depositionally overlie the ophiolite and extracted diagnostic radiolarian assemblages of Aptian (∼125−113 Ma), early–middle Albian (∼113−105 Ma) and Turonian (∼93.9−89.8 Ma) ages. These results suggest that previous Late Cretaceous K–Ar isotopic ages (from 95.3 ± 4.2 Ma to 81.2 ± 1.6 Ma) may have been reset by Late Cretaceous metamorphism or affected by argon loss. Overall, the new Early Cretaceous ages show that the Karpathos ophiolite should not be correlated with the Pindos Nappes of Greece or the ophiolites of Cyprus or Syria but rather with the Lycian Nappes of Turkey and their root located in the Izmir–Ankara–Erzincan Suture Zone. Therefore, the Karpathos ophiolite represents a remnant of the Northern Neotethys, not the Pindos Ocean or the proto-Eastern Mediterranean Basin.

AbstractA total of 66 specimens belonging to eleven snake species, some of which were collected during the field studies of 17-31 July and 3-25 September 2003, and some others which have been previously collected and all have been deposited into the collection of ZDEU (Zoology Dept. Ege University), were evaluated taxonomically. 25 of the specimens belonged to Typhlopidae, 37 to Colubridae, three to Viperidae and one to Boidae. These specimens were evaluated from the points of view of pholidosis, pattern and coloration and morphological measurements. Some biological and ecological information were also given with the brief geological history of eastern Mediterranean region.

Abstract Lymphatic filariasis (LF), a neglected tropical disease, is targeted for global elimination as a public health problem. This article reviews the history of LF control and elimination activities in the countries of the World Health Organization's (WHO) Eastern Mediterranean Region (EMR) over the last 2 decades. In 2000, the estimated at-risk population in EMR countries was 12.6 million people, accounting for approximately 1% of the global disease burden. Of the 22 EMR countries, 3 countries (Egypt, Sudan and Yemen) were LF endemic and the disease was suspected in 4 other countries (Djibouti, Oman, Somalia and Saudi Arabia). After almost 2 decades of implementing sustained control and prevention measures, Egypt and Yemen were successfully validated by the WHO as having achieved the elimination criteria in 2017 and 2019, respectively. In 2018, Sudan completed mapping of LF, reaching 26.2% geographical coverage where mass drug administration (MDA) is required and is scaling-up MDA. Extensive epidemiological assessment indicated the absence of LF transmission in the four suspected countries and no MDA required. Challenges faced during the elimination and post-elimination phases are described and discussed.

Ever since the liberation of Greece over a century ago, the central issues in Greek public life have been the political unification of all Greek-speaking peoples, questions of domestic, social and economic policy, and the elaboration of a satisfactory constitutional regime.Since Greece received at the time of its liberation only a small share of the lands which it considered to be Greek, its foreign policy has always had this goal: the unification under the political sovereignty of the national state of all the territories in the Eastern Mediterranean region where Greek-speaking inhabitants predominate. By the acquisition of the Ionian Islands in 1863, Thessaly in 1881, and Crete, die Aegean Islands, Southern Epirus and Southern Macedonia in 1913, the greater part of this task had been accomplished on the eve of the first World War.

Forest exploitation by humans and their activities has taken place throughout the Mediterranean Basin for centuries. The area formerly called Yugoslavia located on the Balkan Peninsula, is fairly representative of fire conditions in the eastern Mediterranean Sea. Over the centuries different ethnic groups have altered the forest through utilization and the grazing of domestic animals. Possibly the most serious influence has been fire, both man-caused and natural. The author has examined fire in different countries of the region and made some suggestions which might help reduce the number of wildfires and aid in the suppression of those which do occur.

AbstractThe Central Anatolian Crystalline Complex (CACC), situated between the northern and southern oceanic strands of Neotethys, contain a number of little-studied ophiolitic bodies of late Cretaceous age that have a bearing on the Mesozoic development of this region. The pillow lavas and sheeted dykes of the Sarikaraman Ophiolite were originally a comagmatic differentiated series of vesicular, aphyric and olivine-poor, plagioclase—clinopyroxene phyric tholeiites, but now exhibit greenschist facies assemblages. A set of late dolerite dykes cross-cutting the whole volcanic sequence are more chemically evolved and were probably derived from a different source. Relative to N-MORB the lavas and dykes are enriched in some LIL elements (K, Rb, Cs, U, Th and Sr) and depleted in HFS elements (Nb, Ta, Hf, Zr, Ti and Y) and lightREE. In terms of immobile elements the ophiolitic basalts have the broad chemical characteristics of island are tholeiites that were formed in a supra-subduction zone setting, whereas the late dykes are more akin to N-MORB. In this respect the Sarikaraman Ophiolite is similar to other ophiolites found in the eastern Mediterranean region and emphasizes the preservation of this particular environment in the CACC. If all the Central Anatolian Ophiolites (of which the Sarikaraman Ophiolite is one example) were derived via southward thrusting from the Vardar-Izmir-Ankara-Erzincan Ocean branch to the north, age relationships suggest that this segment of ocean crust was relatively short-lived before obduction onto the CACC.

AbstractWhile numerous scholars have compared the Priestly regulations in the Pentateuch to ancient Near Eastern “ritual texts,” the Priestly legal material more generally corresponds in form and style to ancient Near Eastern casuistic law collections than to descriptive or prescriptive “ritual texts.” At the same time, ancient Near Eastern law collections do not contain any ritual or religious ordinances, relating instead primarily to civil and financial affairs or social law and order. This paper examines the formal, substantive, and generic affinities between the Priestly laws and the casuistic Greek “Sacred Laws” inscribed on stone and other materials throughout the eastern Mediterranean basin from the sixth century BCE onwards. Analysis of related Northwest-Semitic and Punic texts, as well as potential precedents from the Hittite world, further contributes to our understanding of theSitz im Lebenof the casuistic Priestly law.
