INTRODUCTION Peacock eye (olive leaf spot), caused by Venturia oleaginea (Castagne) Rossman & Crous (= Spilocaea oleaginea), provokes severe damage to olive in all olive-growing countries. In recent years, the incidence and severity of this disease have increased in Palestine, likely resulting from climate change (Salman et al., 2011). Peacock eye is considered the most important disease attacking olive trees in Palestine, where olive production is very impor- tant, contributing approx. 13% to the national income (Salman et al., 2011; Abuamsha et al., 2013; UNCTAD, 2015).

  • Water Systems at Yasileh
    ARAM, 23 (2011) 619-644. doi: 10.2143/ARAM.23.0.2959676 WATER SYSTEMS AT YASILEH Prof. ZEIDOUN AL-MUHEISEN* (Yarmouk University) Yasileh is located 9 km east of Irbid and 5 km west of ar-Ramtha, in north- ern Jordan. The site of Yasileh has an important geographical location since the area was a crossroad sfor the ancient trading routes between Southern Syria, Jordan and Palestine, in addition to the fact that the land in the sur- rounding area is very fertile and very well suited to agriculture. The Wadi ash-Shallalih area, including the site of Yasileh, a natural basin in which to collect rainwater where the annual rainfall for the Yasileh area has been esti- mated at between 400-500 mm. A sufficient supply of water was also ensured by cisterns cut into the rocky sides of Wadi Yasileh, as well as a spring located 1 km to the north of the site. Yasileh has a variety of water sources, storage and delivery systems including springs, reservoirs, wells, dams, tunnels and canals. Since 1988, ten campaigns have been carried out by the Institute of Archeology and Anthropology at Yarmouk University. Based on the results of the archaeological activities in the site headed by the author, this article will shed light on the water systems at Yasileh. INTRODUCTION The Yasileh site is located in Wadi ash-Shallalih, which represents the lower reaches of Wadi Warran (Schumacher 1890, 108). Wadi ash-Shallalih runs through the area between Hauran and ‘Ajlun and is fed by tributaries arising in the ‘Ajlun mountains; running west of the village of Suf, it continues north- ward to reach the area of ar-Ramtha, where it is known as Wadi Warran.

Since they lack a surviving narrative history of their own, in approaching the Nabataeans one necessarily relies heavily upon the commentaries of outside observers, such as the Greeks, Romans, and Jews, as well as upon comparisons of Nabataean material culture with Classical and Near Eastern models. These approaches have elucidated much about this

    chapter 9 East of the River Jordan Several architectural characteristics (such as stone doors and re-used Roman monuments) found just to the north, in the Hauran, were also to be found further to the south, in what is now northern Jordan, where the cadence of settlement also seems to match.1 The area was still awaiting comprehensive archaeological investigation at the beginning of the 20th century,[1] but schol- ars such as David Kennedy have illuminated Jordan’s military history, as have others her legacy of churches.2 Irbid Oliphant (who largely parrotted Seetzen[2]) visited one house at Irbid / Abila, which was missing the actual door: “the framework of the door was all carved stone; and there were sockets in the lintels and thresholds for pivots to work in, showing that formerly the door was a slab of stone turning on a stone hinge.”[3] More might have survived in 1810, when Seetzen visited the town, finding it deserted: Some beautiful remains of the ancient walls are to be discovered, together with a number of arches, and of columns of marble, basalt, and grey granite. On the outside of these ancient walls I found also a great many columns, two of which were of extraordinary magnitude, from which I concluded that there must have been formerly in this spot a considerable temple.[4] Merrill saw “fine Roman ruins, and some evident marks of very great antiquity” at Irbid in 1881, including “a small, well-preserved Roman building, which may have been a temple or a tomb, was an inscription within a nicely carved wreath, perfectly round.”[5] He questioned people about Roman roads and antiquities in the vicinity, and was told what they said was the road: 1 El-Khouri 2009: the archaeological landscape in north-west Jordan, including (27–60) sites, roads and agriculture, and 61–139 for catalogue of Roman sites.

Published by American Research Institute for Policy Development DOI: 10.15640/jns.v6n2a12 URL: https://doi.org/10.15640/jns.v6n2a12 Tourism Impacts in the Site of Umm Qais: An Overview Mairna H. Mustafa1, Dana H. Hijjawi2 and Fadi Bala'awi3 Abstract This paper aims at shedding the light on the different impacts of tourism development in the site of Umm Qais (Gadara) in Jordan. Despite the economic benefits gained by tourism, deterioration has been witnessed in this site due to damage of archaeological features as well as the displacement of the local community. Implications were suggested to achieve a more sustainable tourism development in the site. Keywords: Umm Qais (Gadara), Tourism impacts, Sustainable development, Local community of Umm Qais. Introduction The Site of Umm Qais (the Greco-Roman Decapolis town of Gadara) is 120 Km north of Amman, and 30 Km northwest of Irbid (both located in Jordan). The site is 518 meters above sea level and is over looking both Lake Tiberias and the Golan Heights, which creates a great point to watch nearby lands across the borders (Teller, 2006) (Map 1). The city was mentioned in the New Testament as χωρά των͂ Γαδαρηνων,͂ (chorā̇ ton̄̇ Gadarenō n)̄̇ or “country of the Gadarenes” (Matthew 8:28), it's the place where Jesus casted out the devil from two men into a herd of pigs (Matthew 8: 28-34), mentioned as well in the parallel passages as (Mark 5:1; Luke 8:26, Luke 8:37): χωρά των͂ Γερασηνων,͂ chorā̇ ton̄̇ Gerasenō n̄̇ “country of the Gerasenes.” (Bible Hub Website: http://biblehub.com/commentaries/matthew/8-28.htm).

Studies in Fungi 5(1), 6–16, Doi 10.5943/sif/5/1/2 Abstract Microfungi are commonly inhabited soil with various roles. The present study was conducted in order to isolate and identify microfungi from soil samples in Serdang, Selangor, Malaysia. In this study, the soil microfungi were isolated using serial dilution technique and spread plate method. A total of 25 isolates were identified into ten genera based on internal transcribed spacer region (ITS) sequence analysis, namely Aspergillus, Clonostachys, Colletotrichum, Curvularia, Gliocladiopsis, Metarhizium, Myrmecridium, Penicillium, Scedosporium and Trichoderma consisting 18 fungi species. Aspergillus and Penicillium species were claimed as predominant microfungi inhabiting the soil. Findings from this study can be used as a checklist for future studies related to fungi distribution in tropical lands. For improving further study, factors including the physicochemical properties of soil and anthropogenic activities in the sampling area should be included.

  • Results of the Iv World Congress of Terraced Landscapes
    RESULTS OF THE IV WORLD CONGRESS OF TERRACED LANDSCAPES ORGANIZED BY ITLA MAC IN CANARY ISLANDS, SPAIN From 13 to 22 March 2019 the IV World Congress of Terraced Landscapes Re- enchanting Terraces has been held in La Gomera, Canary Islands (Spain). The Congress, organized by the International Terraced Landscapes Alliance (ITLA) had the objective to show the significative value of the terraced landscapes as active resources that can be used to meet new social demands for food, agriculture, leisure, education, social interaction and finally quality of life with friendly, beautiful and safe landscapes against natural risks. The Congress focuses on the specific problems of the Canary Islands, Madeira, Azores and Cape Verde to develop a global thinking on the perspectives of these territories in the future. More than 150 experts from different countries and representing all the various institutions that have organized the event in Canary Islands participated to the Congress. From 16 to 18 March, the congress participants, divided into 14 groups, moved to the eight islands of El Hierro, Fuerteventura, Gran Canaria, La Gomera, Lanzarote, La Palma, Tenerife and Madeira, to visit the productive and abandoned terraces, to discuss with owners and farmers, to exchange with the population and the local institutions about the perspectives of their development. As a result of these visits, specialists in various disciplines related to the environment, land management, geography or architecture have travelled to La Gomera from the different islands to participate in the final event of the IV World Congress of Terraced Landscapes. On this occasion the representative of the local government of La Gomera, valuing the great contribution of the event, has stressed that in the island are being implemented 50 projects of rehabilitation of terraces that require sustainable development and economic strategies to ensure their conservation.

Other species are considered enzyme factories or are common indoor air allergens. Although DNA sequences are essential for robust identification of Penicillium species, there is currently no comprehensive, verified reference database for the genus. To coincide with the move to one fungus one name in the International Code of Nomenclature for algae, fungi and plants, the generic concept of Penicillium was re-defined to accommodate species from other genera, such as Chromocleista, Eladia, Eupenicillium, Torulomyces and Thysanophora, which together comprise a large monophyletic clade.

Apartado Postal 63, Xalapa, Veracruz 91000, México Abstract — Thirty collections of Loculoascomycetes from the Ajos-Bavispe National Forest Reserve and Wildlife Refuge, the Pinacate and Great Altar Desert Biosphere Reserve, and the Sierra of Alamos-Rio Cuchujaqui Biosphere Reserve, in Sonora, Mexico were studied. Ten new records for the Mexican mycobiota are presented: Capronia montana, Chaetoplea crossata, Didymosphaeria futilis, Glonium abbreviatum, Hysterographium mori, Montagnula infernalis, Patellaria atrata, Rhytidhysteron rufulum, Thyridaria macrostomoides, and Valsaria rubricosa. Photographs of macro- and microscopic characters are given for some species. Key words: Chaetothyriales, Hysteriales, Melanommatales, Patellariales, Pleosporales Introduction The term Loculoascomycetes is used for ascomycetes with bitunicate asci and septate ascospores (Kirk et al. 2008). There is some controversy over the taxonomy of the genera in this group, e.g., Valsaria, because authors such as Dennis (1978) have placed them in the Loculoascomycetes owing to their bitunicate asci while others, such as Barr (1990a), have included them in Pyrenomycetes arguing the presence of unitunicate asci. Boehm et al. (2009) studied four nuclear genes in different species of Loculoascomycetes and have proposed changes to the current taxonomy, e.g., Rhytidhysteron rufulum which was previously included in order Patellariales has been tentatively moved to the Hysteriales.
