Regional experts also provided a review of the status of mangrove habitats in Egypt and Saudi Arabia. This document is a synthesis of these reports. It gives an indication of the status of mangroves in the Region1 and guidelines for mangrove rehabilitation, conservation and management. Avicennia marina is the most abundant mangrove species; it was reported in all mangrove areas in the Region. Relatively thick and well grown Rhizophora mucronata stands coexist in a few areas, particularly in Djibouti, while some other less developed Rhizophora mucronata stands occur in Yemen and

  • Avicennia Marina Mangrove Forest
    MARINE ECOLOGY PROGRESS SERIES Published June 6 Mar Ecol Prog Ser Resource competition between macrobenthic epifauna and infauna in a Kenyan Avicennia marina mangrove forest J. Schrijvers*,H. Fermon, M. Vincx University of Gent, Department of Morphology, Systematics and Ecology, Marine Biology Section, K.L. Ledeganckstraat 35, B-9000 Gent, Belgium ABSTRACT: A cage exclusion experiment was used to examine the interaction between the eplbenthos (permanent and vls~tlng)and the macroinfauna of a high intertidal Kenyan Avicennia marina man- grove sediment. Densities of Ollgochaeta (families Tubificidae and Enchytraeidae), Amphipoda, Insecta larvae, Polychaeta and macro-Nematoda, and a broad range of environmental factors were fol- lowed over 5 mo of caging. A significant increase of amphipod and insect larvae densities in the cages indicated a positive exclusion effect, while no such effect was observed for oligochaetes (Tubificidae in particular), polychaetes or macronematodes. Resource competitive interactions were a plausible expla- nation for the status of the amphipod community. This was supported by the parallel positive exclusion effect detected for microalgal densities. It is therelore hypothesized that competition for microalgae and deposited food sources is the determining structuring force exerted by the epibenthos on the macrobenthic infauna. However, the presence of epibenthic predation cannot be excluded. KEY WORDS: Macrobenthos . Infauna . Epibenthos - Exclusion experiment . Mangroves .

Aljaghthmi, H.M. Heba and I.M. Abu Zeid Department of Biological Sciences, Faculty of Sciences, King Abdulaziz University, P.O. Box 139109, Jeddah 21323, Saudi Arabia Abstract: The increased occurrences of diabetes have led to the utilization of the curative plants in search of the best remedies. The usage of medicinal plants has been embraced worldwide since it is a critical part of the public healthcare. Rhizophora mucronata and Avicenna marina are vulnerable plants that require protection for their continued significance in the cure of diabetes. The two plants have proved to be antiviral and antibacterial in nature. Traditionally, the Rhizophora mucronata and Avicenna marina were utilized to cure diabetes. Although there is tremendous progress in the diabetes cure through the oral hypoglycemic compounds, there is a consistent search for the newer medicines. Mostly these mangrove trees have antidiabetic activity despite the fact that they have not been accepted. However, the traditional medicine system has used such plants with success. This review showed some of the previous data on the Rhizophora mucronata and Avicenna marina that were tested on the rats in medical laboratories. Key words: Rhizophora mucronata Avicenna marina Diabetes Bioactive compounds. INTRODUCTION that the species have bioactive compounds potential for long-term treatment of diabetes and other significant The diabetes complications involve the retinal, renal disorders. The two plants are not directly consumed as and the cardiovascular complications.

    l'.3350 DEPOsmON AND DISSOLUTION OF THE MIDDLE DEVONIAN PRAIRIE FORMATION, WilLISTON BASIN, NORTH DAKOTA AND MONTANA by: Chris A. Oglesby T-3350 A thesis submined to the Faculty and the Board of Trustees of the Colorado School of Mines in partial fulfillment of the requirements for the degree of Master of Science (Geology). Golden, Colorado Date f:" /2 7 /C''i::-- i ; Signed: Approved: Lee C. Gerhard Thesis Advisor Golden, Colorado - 7 Date' .' Samuel S. Adams, Head Department of Geology and Geological Engineering II T-3350 ABSTRACf Within the Williston basin, thickness variations of the Prairie Formation are common and are interpreted to originate by two processes, differential accumulation of salt during deposition, and differential removal of salt by dissolution. Unambiguous evidence for each process is rare because the Prairie/Winnipegosis interval is seldom cored within the U.S. portion of the basin. Therefore indirect methods, utilizing well logs, provide the principal method for identifying characteristics of the two processes. The results of this study indicate that the two processes can be distinguished using correlations within the Prairie Formation. Several regionally correlative upward-brining, and probably shoaling-upward sequences occur within the Prairie Formation .. Near the basin center, the lowermost sequence is transitional with the underlying Winnipegosis Formation. This transition is characterized by thinly laminated carbonates that become increasingly interbedded with anhydrites of the basin-centered Ratner Member, the remainder of the sequence progresses up through halite and culminates in the halite-dominated Esterhazy potash beds. Two overlying sequences also brine upwards, however, these sequences lack the basal anhydrite and instead begin with halite and culminate in the Belle Plaine and Mountrail potash Members, respectively.

  • Ecological Patterns and Status of the Reefs of Sudan
    Proceedings of the 11th International Coral Reef Symposium, Ft. Lauderdale, Florida, 7-11 July 2008 Session number 18 Ecological patterns and status of the reefs of Sudan R. Klaus1, J. Kemp1, M. Samoilys1,2, H. Anlauf1, S. El Din3, E.O. Abdalla3, T. Chekchak1 1) Equipe Cousteau, 92 Avenue Kleber, 75116 Paris, France 2) CORDIO East Africa, P.O.BOX 24562, Karen 00502, Nairobi, Kenya 3) Red Sea University, Port Sudan, Sudan Abstract. Sudan borders the western shore of the Red Sea, a sea recognised as being of global importance for marine biodiversity. A survey carried out during October / November 2007 provided the opportunity to assess the current status of the reefs, many of which have never previously been surveyed. Within the Sudanese Red Sea there is a pronounced biogeographical transition from reef communities that are characteristic of the northern Red Sea to those more representative of the southern Red Sea. Recreational and extractive use of resources is still moderately low however the condition of the reefs and the abundance of resources is highly variable. There are low abundances of several key families of commercial fin fish (particularly groupers and larger snappers) and invertebrate groups (particularly sea cucumbers and larger gastropod molluscs). There is also a conspicuous absence of sea urchins (Diadema spp. and Echinometra spp.) from many sites. The reefs of Sudan were impacted by previous coral bleaching events, although the extent of mortality was influenced by variability in community composition and local environmental conditions. The biogeographic trends within Sudanese waters and the variability in resource abundance and reef condition all have important implications for management planning.

  • Chapter 2 Paleozoic Stratigraphy of the Grand Canyon
    CHAPTER 2 PALEOZOIC STRATIGRAPHY OF THE GRAND CANYON PAIGE KERCHER INTRODUCTION The Paleozoic Era of the Phanerozoic Eon is defined as the time between 542 and 251 million years before the present (ICS 2010). The Paleozoic Era began with the evolution of most major animal phyla present today, sparked by the novel adaptation of skeletal hard parts. Organisms continued to diversify throughout the Paleozoic into increasingly adaptive and complex life forms, including the first vertebrates, terrestrial plants and animals, forests and seed plants, reptiles, and flying insects. Vast coal swamps covered much of mid- to low-latitude continental environments in the late Paleozoic as the supercontinent Pangaea began to amalgamate. The hardiest taxa survived the multiple global glaciations and mass extinctions that have come to define major time boundaries of this era. Paleozoic North America existed primarily at mid to low latitudes and experienced multiple major orogenies and continental collisions. For much of the Paleozoic, North America’s southwestern margin ran through Nevada and Arizona – California did not yet exist (Appendix B). The flat-lying Paleozoic rocks of the Grand Canyon, though incomplete, form a record of a continental margin repeatedly inundated and vacated by shallow seas (Appendix A). IMPORTANT STRATIGRAPHIC PRINCIPLES AND CONCEPTS • Principle of Original Horizontality – In most cases, depositional processes produce flat-lying sedimentary layers. Notable exceptions include blanketing ash sheets, and cross-stratification developed on sloped surfaces. • Principle of Superposition – In an undisturbed sequence, older strata lie below younger strata; a package of sedimentary layers youngs upward. • Principle of Lateral Continuity – A layer of sediment extends laterally in all directions until it naturally pinches out or abuts the walls of its confining basin.

  • Martian Crater Morphology
    ANALYSIS OF THE DEPTH-DIAMETER RELATIONSHIP OF MARTIAN CRATERS A Capstone Experience Thesis Presented by Jared Howenstine Completion Date: May 2006 Approved By: Professor M. Darby Dyar, Astronomy Professor Christopher Condit, Geology Professor Judith Young, Astronomy Abstract Title: Analysis of the Depth-Diameter Relationship of Martian Craters Author: Jared Howenstine, Astronomy Approved By: Judith Young, Astronomy Approved By: M. Darby Dyar, Astronomy Approved By: Christopher Condit, Geology CE Type: Departmental Honors Project Using a gridded version of maritan topography with the computer program Gridview, this project studied the depth-diameter relationship of martian impact craters. The work encompasses 361 profiles of impacts with diameters larger than 15 kilometers and is a continuation of work that was started at the Lunar and Planetary Institute in Houston, Texas under the guidance of Dr. Walter S. Keifer. Using the most ‘pristine,’ or deepest craters in the data a depth-diameter relationship was determined: d = 0.610D 0.327 , where d is the depth of the crater and D is the diameter of the crater, both in kilometers. This relationship can then be used to estimate the theoretical depth of any impact radius, and therefore can be used to estimate the pristine shape of the crater. With a depth-diameter ratio for a particular crater, the measured depth can then be compared to this theoretical value and an estimate of the amount of material within the crater, or fill, can then be calculated. The data includes 140 named impact craters, 3 basins, and 218 other impacts. The named data encompasses all named impact structures of greater than 100 kilometers in diameter.

  • The Arabian Gulf
    Chapter 1 The Arabian Gulf Grace O. Vaughan, Noura Al-Mansoori, John A. Burt New York University Abu Dhabi, Abu Dhabi, United Arab Emirates 1.1 THE REGION Bound by deserts and located between the north-eastern Arabian Peninsula and Iran, the Arabian Gulf (also known as the Persian Gulf, and hereafter known as “the Gulf”) is bordered by eight rapidly developing nations. The Gulf is located in the subtropics between 24°N and 30°N latitude and 48°E and 57°E longitude (Fig. 1.1), and is considered as a biogeographic subprovince of the northwestern Indian Ocean (Spalding et al., 2007). During summers, the Gulf is the hottest sea on the planet, particularly in the shallow southern basin where sea surface temperatures (SSTs) regu- larly exceed 35°C in August. Sea temperatures are also highly variable among seasons, ranging over 20°C between summer and winter. Geologically, the Gulf is relatively young with coastlines that formed only in the past 3000–6000 years when polar ice sheets receded (Riegl & Purkis, 2012a). Today, the Gulf is bordered to the northeast by the Zagros mountains in Iran and the Hajar mountains in the Musandam peninsula and in the southwest by the sedimentary Arabian coast (Purser & Seibold, 1973). Presently, it covers an area of 250,000 km2 (Riegl & Purkis, 2012a). Generally, terrestrial systems sur- rounding the Gulf are arid to hyperarid (Riegl & Purkis, 2012a), limiting the input of freshwater to this semienclosed sea. The main freshwater input enters at the northern Gulf at the Shatt Al Arab waterway through the Tigris, Euphrates, and the Karun rivers (Sheppard, Price, & Roberts, 1992), although recent damming efforts have resulted in substantial reductions in freshwater discharge from these rivers (Sheppard et al., 2010).

  • Spatial Structure and Genetic Variation of a Mangrove Species (Avicennia Marina (Forssk.) Vierh) in the Farasan Archipelago
    Article Spatial Structure and Genetic Variation of a Mangrove Species (Avicennia marina (Forssk.) Vierh) in the Farasan Archipelago Rahmah N. Al-Qthanin 1,* and Samah A. Alharbi 2 1 Biology Department, College of Sciences, King Khalid University, Abha 61421, Saudi Arabia 2 Biology Department, College of Applied Sciences, Umm-Al-Qura University, Makkah 21421, Saudi Arabia; [email protected] * Correspondence: [email protected] Received: 12 August 2020; Accepted: 18 November 2020; Published: 30 November 2020 Abstract: Avicennia marina (Forssk.) Vierh is distributed in patches along the Farasan archipelago coast and is the most common mangrove species in the Red Sea. However, to date, no studies have been directed towards understanding its genetic variation in the Farasan archipelago. In this investigation, genetic variations within and among natural populations of Avicennia marina in the Farasan archipelago were studied using 15 microsatellite markers. The study found 142 alleles on 15 loci in nine populations. The observed (Ho) and expected (He) heterozygosity values were 0.351 and 0.391, respectively, which are much lower than those of earlier studies on A. marina in the Arabian Gulf. An inbreeding effect from self-pollination might explain its heterozygote deficiency. Population genetic differentiation (FST = 0.301) was similar to other mangrove species. Our findings suggest that the sea current direction and coastal geomorphology might affect genetic dispersal of A. marina. The more isolated populations with fewer connections by sea currents exhibited lower genetic variation and differentiation between populations. The genetic clustering of populations fell into three main groups—Group 1 (populations of Farasan Alkabir Island), Group 2 (populations of Sajid Island), and Group 3 (mix of one population of Farasan Alkabir Island and a population of Zifaf Island).

ABSTRACT Nabq protectorate is one of wonderful natural places in Egypt. It is characterized by diversity of bio-lives such as man- grove forests, coral colonies, wild life plants and migratory birds. Ongoing growth of tourism industries at Sharm El Sheikh northward into the Nabq protectorate causes severe hazards on its natural resources. The aim of the present study is to assess the present geo-environmental hazards in the Nabq protectorate. Assessment includes the analysis of satellite images, topographical, geological and other ancillary geological data using GIS technology. GIS data analyses indicate that the area is under threat from some of geo-hazards. Rough topography and mass wasting with high prob- ability of flash flooding threaten different constructions in this area. The mobilization of coastal sand dunes, wave ac- tion and tidal currents are natural impacts on Nabq ecosystems, where moved dunes leave clay soils that are removed in some places by tropical storms increasing sea water turbidity that threaten the corals and other living organisms in the tidal flat region.
