Revision Of The Genus Salvia L. (labiatae) In The Mediterranean And The Aegean Geographic Regions Of Turkey

Celep, Ferhat 01 October 2010 (has links) (PDF)
A revision of the Mediterranean and the Aegean geographic regions of Turkey of Salvia L. (Labiatae) is presented. According to the results, the study area has 60 taxa, 32 of which are endemic (mainly local endemics), 5 of which are non-endemic rare, and the remaining 23 taxa are widely distributed. The rate of endemism is 53% in the area. At the beginning of the thesis, history and worldwide distribution of the family and the genus are briefly given. Phylogenetic studies and infrageneric grouping of the genus are discussed. As well as, recent studies on the genus such as taxonomical, morphological, micromorphological and karyological are provided. Geographic, phytogeographic, topographic, and climatic features of the area are explained. Since 2005, about 2000 specimens have been collected and examined as the research materials. In addition, a large number of specimens have been seen and studied in ANK, AEF, BM, E, ERCIYES, G, GAZI, HUB, K, KNYA, LE, ISTE and ISTF herbaria. Digital photos of some specimens including type specimens have been seen from B, W and A herbaria. In the field when the specimens were detected geographical location (including GPS), habitat, phenological data and relevant field observations were all recorded. In the study, comparative morphological characters and their variations are discussed Anatomical features, such as root, stem, leaf and petiole, micromorphological properties, such as trichome, pollen and nutlet, of the species are comprehensively studied and their taxonomic implications are discussed. According to field studies and literature surveys, endemism, pyhtogeography, habitat, phenology, chorology, new distribution areas and conservation status of the species are determined. Infrageneric delimitation of the species using multivariety analysis is performed. In addition, first sectional key and sectional grouping of the species are made. As well as, identification key of the species is given. At the end of the thesis, expanded and corrected description, address, photographs and some notes on taxonomy of the species are given. The taxonomic studies revealed one new species, Salvia marashica, two new varieties, S. sericeo-tomentosa var. hatayica, S. cadmica var. bozkiriensis, one new combination, S. aucheri subsp. canescens and one new record, S. viscosa. As well as, S. sericeo-tomentosa and S. quezelii are rediscovered.

Specially Protected Areas Within The Context Of The Mediterranean Environmental Programme

Zorlu, Eda 01 December 2011 (has links) (PDF)
The enclosed and semi-enclosed seas are the most severely degraded and fragile ecosystems which necessitates immediate political responses. The problems encountered in relation to biological decline and habitat loss requires a special attention due to their unique value for the whole marine and coastal systems. The main purpose of this thesis is to analyze the contribution of the Mediterranean Environmental Programme to the protection and the preservation of the natural resources and biodiversity with a special focus on Turkey. The Mediterranean Environmental Programme which was launched in 1975 with an Action Plan and conducted through an umbrella convention which addresses this issue through the SPA/BD Protocol. In line with the SPA/BD Protocol over 750 areas are designated as specially protected areas and 25 areas as SPAMIs throughout the Mediterranean. Turkey as a Contacting Party to the 1995 Barcelona Convention and the SPA/BD Protocol, declared specially environmental protected areas which amount to 12.842,46 km2 . This thesis argues that the Mediterranean Environmental Programme provides a dynamic and flexible tool for the Mediterranean countries to address marine related problems including the biodiversity and protected areas. Whereas the ultimate success of the cooperation lies in effective implementation at national level which depends on the will of the decision makers, practitioners and the various other stakeholders / the responsive characteristics of the legislative and administrative processes.

A Coupled Modelling Attempt Of Hydrodynamics And Ecosystem Of Northern Levantine Basin

Aydogdu, Ali 01 July 2012 (has links) (PDF)
A three-dimensional ocean model, ROMS, has been utilized to simulate the hydrodynamics and the ecosystem dynamics of the Northern Levantine Basin circulation. The model is one-way nested inside a coarser resolution Mediterranean Sea eco-hydrodynamics model, forced with realistically updated surface and lateral fluxes of momentum, mass, heat and nutrients. Scenario runs representing present and future time-slices of 5 years each have been used to investigate sensitivity to climate in the near future. Other sensitivity tests depending on model parameters and options have been performed. It is revealed that the Asia Minor Current, dominating the basin circulation, divides the basin into the two basic regions of coastal and open sea characteristics. Although satisfactory results are reached for the general behaviour of the ecosystem, the model tends to overestimate the surface chlorophyll concentration. Sea surface patterns of variables predicted by the model are compared with satellite data indicate general agreement in the seasonal patterns. Based on the selected climate change scenario for 30-40 year difference of the time slices, rises of 0.33

Classical biological control of Mediterranean fruit fly, Ceratitis capitata (Wiedemann), (Diptera:Tephritidae): natural enemy exploration and nontarget testing

Trostle Duke, Marcia Katherine 16 August 2006 (has links)
This work covers stages one through seven (of nine stages) of a classical biological control program for Mediterranean fruit fly (=medfly), Ceratitis capitata (Wiedemann). Major research objectives concentrate on stage five (exploration and collection of natural enemies), and stage seven (testing and selecting natural enemies for additional work). Coffee was collected monthly from three locations in Kenya from November 1997 through July 1999. Four species of tephritid flies and ten parasitoid species were recovered. Four guilds of parasitoids were recorded, and two egg-prepupal endoparasitoids, Fopius caudatus (Szépligeti) and F. ceratitivorus (Wharton), were discovered. The oviposition behavior of these two species is contrasted. Domination of this tropical parasitoid assemblage by koinobionts is discussed relative to the dominance of temperate fruit-infesting tephritid systems by idiobionts. Fruit handling procedures were examined for impact on overall percent emergence and specifically percent emergence of flies versus parasitoids. It was determined that stirring samples had a significant positive effect on overall emergence, however daily misting of fruit did not. The only treatment without a significant bias in fly emergence over parasitoids was the stirred/dry treatment. Effects of these results on rearing procedures are discussed. Host specificity and host suitability of parasitoids reared from coffee were examined via: (1) association of parasitoids with host flies based on characteristics of the fly puparia from which parasitoids emerged, (2) rearing of cucurbit infesting tephritids and their parasitoids in Kenya, (3) rearing of flowerhead infesting tephritids and their parasitoids in Kenya and Hawaii, and (4) host range testing of Psyttalia species in Kenya and Hawaii. These results are discussed in terms of their utility for predicting nontarget effects. Psyttalia concolor (Szépligeti) was shipped to Hawaii and tested against the nontarget gall forming tephritid Procecidochares utilis Stone introduced to control the weed Ageretina adenophora (Maui pamakani). Psyttalia concolor failed to attack the gall-forming P. utilis both in choice and no-choice tests, but readily attacked tephritid larvae offered in fruit in choice tests. Recommendations for further testing and release of the parasitoids from Kenya are discussed for Hawaii and Latin America.

EU:s grannskapspolitik i Medelhavsregionen : En säkerhetspolitisk analys av Medelhavssamarbetet

Eriksson, Roger January 2009 (has links)
<p>Abstract</p><p>The thesis investigates how the European Union promotes stability and security in the Mediterranean region. The aim is to analyse the European Union’s security ambitions with Euro-Mediterranean Partnership, the Barcelona Process. An analytical framework with five sectors (military, political, economic, environmental and societal), based on the Copenhagen School’s theories about security sectors and securitization, is used for the analysis. Within the framework threats, objectives and methods are categorized into each security sector. Then it is possible to distinguish if any sector is more prioritised by the EU. Qualitative text analysis is used to examine relevant EU-documents. The result of the analysis shows that the European Union prioritizes the economical and societal sector in promoting peace and security within the Euro-Mediterranean Partnership. Through economical integration and cultural dialogue, the EU tries to enhance security and stability. The EU emphasises the importance of global governance and international law for a stable peace. The study concludes that the widened concept of security, within the Copenhagen School, can help to explain the European Union’s work inside the Euro-Mediterranean Partnership.</p>

Title from PDF of title page. / Document formatted into pages; contains 260 pages. / Thesis (M.A.)--University of South Florida, 2003. / Includes bibliographical references. / Text (Electronic thesis) in PDF format. / ABSTRACT: The study of prehistoric trade and exchange networks in the Western Mediterranean is directly linked to the identification and location of commodities available to Neolithic communities in that region. One of these commodities is a volcanic glass commonly known as obsidian. This investigation focused on the procurement, processing, and distribution of obsidian from the island of Pantelleria, situated between the southwestern coast of Sicily in the Straits of Sicily and the northeastern coast of Africa near Cape Bon, Tunisia. Previous studies indicate that there are several chemically different source areas on the island. Research involved the identification of primary obsidian deposits and the collection of samples from primary and/or secondary sources. / ABSTRACT: The position of each collection point was recorded using GPS coordinates, photographs, and physical descriptions, including accessibility and geological matrix. Additional information regarding the size, frequency, and grade (i.e. quality for tool production) was also noted. / System requirements: World Wide Web browser and PDF reader. / Mode of access: World Wide Web.

Fantasy, Leisure, and Labor: A Story of Temple Terrace's Historic Architecture

Hostetler, Rachelle 01 January 2011 (has links)
The purpose of this project is to explore how the community planning and style of housing of Temple Terrace Estates embodies the socio-economic conflicts inherent to the United States in the 1920s. To account for missing narratives, I will approach this research from a critical cultural perspective. I chose this approach as a way to investigate the power dynamics in the city during the time it was known as Temple Terrace Estates Inc. The Estates attracted investors by encouraging northerners to purchase a Mediterranean Revival or Spanish Colonial style villa in conjunction with a parcel of a large orange grove, which would be tended by paid laborers. The rigorous nostalgia for a colonial past resulted in marginalization of the laboring class and a loss of their voice in history. Thus, my objective is to bring attention to unrepresented experiences that exist within a dominant narrative The following chapters outline the history of Temple Terrace Estates, examine primary sources, and discuss my experience of living in the city. They also explain the theories and methods I use in the analysis such as space/place theory, critical cultural theory, and suburban theory. I tell the story of the conception and construction of The Estates as part of the story of Tampa, Florida, and the United States during the 1920s. Next, I examine the presence of both domestic and agricultural labor in the Estates and discuss the inherent exclusion of laborer's voices in the city's history. I analyze maps, ads, marketing, newspaper thesiss, housing styles, and agricultural practices of the Estates. Knowledge of the city's past provides a way to create meaning in contemporary issues such as historic preservation, crime, and education in the city. Addressing social inequality and implied violence in the history of labor at the Estates might strengthen current accusations of continued racism. However, the omission of the voices of laborers also perpetuates secrecy and mistrust. If Temple Terrace's recent initiative toward historic status is to succeed, there must be support from the community. Scholars and community members of Temple Terrace must acknowledge the continual re-production and re-presentation of the past with a more inclusive narrative. This study demonstrates that the application of critical cultural theory has relevant application today in its ability to diffuse current conflict and aid in historic preservation. Inclusive narratives of the past can help produce safer and more beautiful more beautiful communities for the future.

Commercial navigation in the Greek and Roman world

Davis, Danny Lee 16 October 2012 (has links)
The economic development of Greece and Rome hinged directly on the ability of commercial vessels to transport large volumes of goods across the Mediterranean and Black Sea. Archaeology has revealed the sizes, construction methods and cargos of these ships, but the navigational techniques that were employed to direct them from port to port remain unclear and elusive. In ancient literature, the oft-repeated themes of storm, shipwreck and death at sea led to the popular assumption among scholars that seafarers developed habits to minimize their exposure to this hostile element--hugging the shore to avoid the open sea, putting in at night, sailing only in summer, and using 'seafaring manuals' to help guide their way. While several recent studies have made some strides in overturning this overly simplistic view by highlighting aspects of navigation in certain areas and in certain periods, the 'standard model' lingers in both scholarly and popular imagination. This study offers a comprehensive review of the scattered textual and archaeological evidence pertaining to ancient seafaring and navigation, and a major reinterpretation of ancient commercial navigation in both periods. Chapters 2-3 explore the parameters of the maritime environment (coasts, winds, currents and visibility) and the human responses to them in the form of ships, seasonal rhythms and maritime corridors. Chapters 4 and 5 discuss the ways in which Greek and Roman sailing masters accounted for the fundamental requirements of navigation--the determination of direction, position, speed and distance--using wind roses as a 'compass' and various stars and star groups at night. Chapter 6 treats the question of whether seafarers used written guides or experience, or both, to help determine their position. Chapter 7 explores the historical figure of the sailing master himself and integrates a wide range of evidence to reconstruct the navigational routines of the crews of Alexandrian grain ships during the Roman imperial era. My research concludes that both coastal and open-sea sailing were matters of routine in the commercial sector, that commercial seafarers did indeed sail at night and employ the stars to deduce navigational information, that winter sailing was a widespread practice, and that crews employed navigational strategies to weather storms, usually successfully. / text

Encountering the monstrous masculine : an exploration of monstrous bodies, behaviour and subjectivity in Greek and Roman literature and art

Rae, Heather January 2013 (has links)
This study develops the interpretation of hybrid and human-esque male monsters by examining ambiguous presentations of these figures in Greek and Roman literature and art, putting a fresh perspective on the hero/monster encounter and showing that monsters are developed characters rather than simple heroic attributes, as they are frequently interpreted in modern scholarship. Additional strands running through the thesis are consideration of the hero’s ambiguity through visual similarity to monsters and through shared characteristics; the relationship between monstrous body and monstrous behaviour; the subjectivity of monsters; how masculinity relates to monstrosity; and how monsters operate within the Other/self discourse as ways of exploring human behaviour and relationships in the two monster tale types of heroic encounter and love story. As well as looking at how media and genre affect characterisation, where relevant, the political and social contexts of Greece and Rome will form a background to considering how monsters are presented. This thesis explores the full range of the male monster’s ambiguity (humanised through gestures, clothing, or body; placed into a social context by humanising, or by relationships with humans; given subjectivity) and monstrosity (they explore excessive human behaviour and masculinity), and how the monster is a character in its own right.

The Mediterranean in the English Empire of Trade, 1660-1748

Stein, Tristan 10 September 2014 (has links)
This dissertation reintegrates the Mediterranean into the history of the development of the early modern British Empire. During the seventeenth century, the Mediterranean emerged as a distinct political, legal and commercial space within the wider currents of English expansion. The political and legal regimes of the sea shaped the evolution of the English presence there and the rulers of the Ottoman Empire, the North African regencies, and Italian states such as Tuscany and Genoa limited the expansion of English sovereignty. As a result, the sea offers a different perspective on the history of English expansion than that found in imperial histories set in the Atlantic and Indian Oceans. The development of the English presence in the Mediterranean highlights the relative weakness of the early modern English state and the extent to which other polities limited the expansion of its sovereign authority. However, this dissertation also aims to move beyond an imperial historiography that distinguishes the wider development of English trade and navigation from the growth of English empire. Through the latter half of the seventeenth century and first half of the eighteenth, the Crown's claims to jurisdiction over its subjects and their ships projected English authority into the Mediterranean. This dissertation examines how the English state extended its authority within a pluralistic maritime environment that lay largely beyond the reach of its claims to empire. By studying the jurisdictional contests that arose when the Crown’s claims to authority over its subjects and their ships collided with the sovereignty of Mediterranean polities, it shows how the intersection of diverse sovereign and legal authorities defined the organization of English trade and navigation. Moreover, as the English state extended its authority overseas during the early modern period, it called into question the location of sovereignty and jurisdictional authority in Mediterranean waters as well as in the Atlantic and Indian Oceans. English expansion in the Mediterranean and the political evolution of the sea were part of a global process whereby states and empires sought to establish their authority over oceanic space and networks of trade. / History
