Papilio Demoleus

We review the continuing and extensive spread of Papilio demoleus in south-eastern Turkey and in regions of Turkey and Syria adjacent to the north-eastern Mediterranean. Since the authors documented the arrival of this attractive but potentially destructive papilionid species at coastal areas of Syria in 2019, regular monitoring has confirmed successful overwintering there, as well as in Turkey. As previously indicated, P. demoleus is widely recognized as an invasive pest species in Citrus-growing areas of the world and hence its arrival is of potential economic importance to a region in which citrus is widely grown.

Turbulence Parameters

AbstractWe present long term site testing statistics based on DIMM and GSM data obtained at Dome C, Antarctica. These data have been collected on the bright star Canopus since the end of 2003. We give values of the integrated turbulence parameters in the visible (wavelength 500 nm). The median value we obtained for the seeing are 1.2 arcsec, 2.0 arcsec and 0.8 arcsec at respective elevations of 8m, 3m and 20m above the ground. The isoplanatic angle median value is 4.0 arcsec and the median outer scale is 7.5m. We found that both the seeing and the isoplanatic angle exhibit a strong dependence with the season (the seeing is larger in winter while the isoplanatic angle is smaller).

The Prestige

The chapter considers the geographical literature of early Seleucid writers. It is argued that the first generation of Seleucid geographers appropriated the eastern regions of the Seleucid Empire with their works, often prioritizing useful political narratives over geographical accuracy. As literature, these works seem inexorably linked to the ambition of the early Seleucid court, especially its desire to assert its dominance over vast and previously unchartered territories. Patrocles, for instance, wrote a description of the coastal regions of the Caspian Sea and the Asian river system, parts of which appear to be pure invention. However, his puzzling claims evoked the image of a world empire stretching as far as the edge of the Ocean, bolstering the prestige of the Seleucids. Another work on the north-eastern regions of the empire, by Demodamas, establishes an image of transcendental rule, an image which he anchors in a specifically Hellenistic view of the succession of empires. Thirdly, Megasthenes used his Indica to convey the idea of imperial domination through knowledge, expressed in a colonial key and backed up by targeted cultural reimaginations and precise measurements. The chapter concludes with a discussion of the challenge to Seleucid geography from Alexandria in the form of Eratosthenes, who overturned the Seleucid knowledge of Asia and India while reflecting a distinctly Ptolemaic view of the world.

St. Augustinegrass (Stenotaphrum secundatum [Walt.] Kuntze) is widely adapted to the warm, humid (subtropical) regions of the world. It is believed to be native to the coastal regions of both the Gulf of Mexico and the Mediterranean. St. Augustinegrass is the most commonly used lawn grass in Florida (Figure 1). This publication is intended for homeowners and turfgrass managers that manage St. Augustinegrass in the state of Florida.

This chapter describes the discovery of coastal dead zones, such as the Gulf of Mexico and Chesapeake Bay in North America and the Baltic and Black Seas in Europe. Gene Turner sailed out of Pascagoula, Mississippi, in the spring of 1975, on the first of seven cruises that led to the discovery of the Gulf of Mexico dead zone. In the Chesapeake Bay, an unlikely environmentalist, Charles Officer, sounded the alarm in 1984. The biggest dead zone, however, is the Baltic Sea. Even as early as 1969, ecologists feared hypoxia was turning the Baltic into a “biological desert.” The northwest shelf of the Black Sea turned hypoxic in the 1970s, which killed bottom-dwelling fish like goby and flounder. Many coastal regions around the world have low oxygen waters that devastate marine life and habitats. The early studies emphasized one or two of three ingredients—sewage, fresh water, and plant nutrients—thought to be essential in creating a dead zone. This chapter and Chapter 3 discuss these ingredients before revealing which is most important.

Potential Impact

Seaweeds are considered as a functional food across many regions of the world and has an increasing consumption trend due to its health benefits. However, there is a concern regarding the amount of heavy metals and metalloids present in seaweeds. Therefore, the study aimed to assess the levels of metals present in specific seaweeds and its potential impact on consumption. Considered metal ions were Arsenic (As), Copper (Cu) Chromium (Cr), Nickel (Ni), Cadmium (Cd), Lead (Pb) and Mercury (Hg). At the assessment done at four different sites in the coastal regions of Sri Lanka for chlorophytes, rhodophytes and phaeophytes. Concentration of metals were analyzed using the ICPOES. According to the arrived results, concentration of metals varies as Cr > Ni > Cd > Cu > As > Pb = Hg with having zero concentration for Hg and Pb for all varieties and all sites. It was also found that the least amounts of metals were present at Jaffna site in phaeophytes (Sargassum sp.) and chlorophytes (Ulva sp.) When considering the Hazardous Index of the varieties, least was found in Sargassum sp. in Jaffna site. Studies were repeated for 2 seasons and there are significant differences (p < 0.05) between the dry season and wet season in the concentration of heavy metals present. However, since the seaweeds are grown for commercial purposes only in Jaffna area, it is evident that the chlorophyte and phaeophyte varieties claim very low health risk for potential heavy metals and are suitable for consumption purposes.

Coastal urban phenomenon in the form of high population growth, rapid economic development and inadequate control of the sea, resulting in the use of the sea and coastal regions become more intensive in the last few years. This development led to the expansion of the city was further intensified by the coastal reclamation. Reclamation has been performed in many cities of the world and also in Indonesia, but many constraints. Research on model of sustainable Reclamation is still rare. The purpose of this paper is to formulate a model that could be applied on a coastal reclamation area using an index of sustainability. This research began with literature study of previous researches of developing sustainability index that not focusing yet on coastal reclamation area with the analytic hierarchy process (AHP) and expert choices. Reclamation sustainability index is used to as a tool to develop a sustainable reclamation model. This model will help project of reclamation activities and its relationship with suitable measures to manage the implementation of a sustainable reclamation. Formulation of the model is done by analysis of Structural Equatian Model (SEM) on the Makassar coastal zone and then tested the feasibility to found the appropriate reclamation model.

The cruise industry is one of the most important growth sectors in the entire tourism market. The number of cruise passengers has been increasing in the last 9 years. The market is still growing, despite the global economic instability. North America is the primary market for cruise activities. There is still enormous potential to be found in the worldwide cruise market. The European cruise sector is number two and it is a growing market. The biggest European country is Great Britain. Various interest groups are trying to increase familiarity with the cruise product to grow the market. The fact the cruise market displays strong growth even under difficult circumstances (in times of instability) breeds confidence for the future. The cruise industry can make a huge positive contribution to tourism destinations and generate economic benefits, which makes it a very interesting market for coastal regions. The chapter studies the status of the cruise industry in the world and the future foreseeable evolution of this industry.
