Iraq is located between geographic coordinates 33 00 N, 44 00 E, and occupies a total area of 437,072 square kilometers. Land forms 432,162 square kilometers while water forms 4,910 square kilometers of the total area. Iraq is bordered by Turkey from the north. Iran from the east, Syria and Syria from the west, and Saudi Arabia and Kuwait from the south. Iraq can be divided according to the nature of the land terrain into 4 regions (Mountain Region, Plateau and Hills Regions, The Mesopotamian plain and Jazera and Western Plateau). The climate is mainly of continental, subtropical semi-arid type. The mountain region is of Mediterranean climate. In general, rainfall occurs from December to February or November to April in the mountain region. During winter the average daily temperature is about 16oC dropping at night to 2oC with possibility of frost. In summer however, it is very hot with an average temperature of over 45oC during July and August dropping to 25oC at night. Keywords: Topography, Climate, Iraq.

Tables have been prepared of the average temperature at the Ben Nevis and Fort-William Observatories on each day of the year, using the records of the twenty years 1884 to 1903 inclusive. Table I. gives the average daily temperature at Ben Nevis, Table II. that at Fort-William, and Table III. the differences between them. These tables have been prepared as follows :—Ben Nevis Observatory.—In summer the dry- and wet-bulb thermometers were exposed in an ordinary Stevenson screen 4 feet above ground, and in winter in a smaller-sized double-louvred screen, placed on a ladder-like stand, and moved up or down so as to be always about 4 feet above the surface of the snow. These thermometers were read hourly, and the average of the dry-bulb readings for the 24 hours of each day is taken as the temperature of that day. Table I. is the arithmetical mean of the values so computed on each day of the year.

On the western end of the north coast of Honduras, the outstanding river is the Ulúa, whose basin is formed by the plain of Sula. In the south, the gradually descending steps of the Cordilleras with the open avenues of the Ulúa on the west and her tributaries, the Lindo due south and the Comayagua at the east, bring contact to the wet valley of Sula from the semi-arid interior. Eastward lies the low margin of coast and the lagoons and river systems of the Pijol range. West and southwest is mountain land with an important river valley, the Chamelicon, which merges into the Sula plain. At the north is the open sea, bringing to this region varied influences from many and distant places.

Independent of latitude, scattered populations all over the world need specially designed health and social services with much higher per capita costs than in densely populated parts of the world. This is particularly true of the Arctic region with its harsh environmental conditions and constraints apply. Indeed, it is even more important to establish the nature of numerical highly individual native cultures. In spite of its northerly position, Svalbard (77–80°N) has a relatively mild climate which offers an environment less inhospitable than might be expected at this latitude. The climate, especially on the main island, Spitsbergen, is influenced by an extreme tail of the North Atlantic Drift which keeps the waters of the west and north coasts open for half the year. Extreme Arctic temperatures are rare. Spitsbergen's temperature fluctuates by about 20°C, whereas in castern Siberia the range can be three times as great. The annual average temperature on the west coast is −5°C, seldom falling below −30°C. July is usually around +5°C with an occasional maximum of +20°C. Therefore, the health problems often associated with extremely cold climates are not common in Svalbard.

Climate change and related changes in natural ecosystems are the most important international issues of the twenty-first century. In this regard, modeling the dynamics of plant and animal habitats based on the analysis of their relationships with climate parameters and environmental characteristics becomes an urgent task. Modeling the geographical distribution of species is not possible without geoinformation analysis, which allows you to identify both the boundaries of factors that affect the distribution of the species, and the features of its range. The paper presents the author’s addition to the existing method of ecological and geographical modeling based on GIS technologies that allow to visualize the dynamics of areas in a certain period of time and in connection with changes in bioclimatic parameters. Modeling the spatial distribution of two marker species of ground beetles makes it possible to extrapolate fragmentary data on specific locations over large territories. The created geoinformation models of the predicted areas revealed their changes for different climate scenarios for 2050 and 2070. Based on ecological and geoinformation modeling, it was found that the formation of the modern range of Zabrus tenebrioides is significantly influenced by the average daily temperature amplitude for each month, the maximum temperature of the warmest month and the minimum temperature of the coldest month. The distribution of Pterostichus oblongopunctatus is influenced by the average annual temperature, the average daily temperature amplitude for each month, and the average temperature of the driest quarter; the average temperature of the warmest quarter of the year and the amount of precipitation in the driest month of the year. The geoinformation analysis made it possible to identify the dependence of the number of points of species finds and the values of bioclimatic factors. Maps and graphs of the range of species comfort were created. The main trends of changes in the range of Pterostichus oblongopunctatus under changing climate conditions in the “soft” and “hard” scenarios are revealed. Under the influence of climate change, the area of habitats is reduced and their structure is changed.

The European rabbit (Oryctolagus cuniculus) introduced into New Zealand in the 183Os, has consistently flourished in Central Otago, the upper Waitaki, and inland Marlborough, all areas of mediterranean climate. It has proved difficult to manage in these habitats. The 'rabbit problem' is largely confined to 105,000 ha of low producing land mostly in semi arid areas of Central Otago. No field scale modifications of the natural habitat have been successful in limiting rabbit numbers. The costs of control exceed the revenue from the land and continued public funding for control operations appears necessary. A system for classifying land according to the degree of rabbit proneness is described. Soil survey and land classification information for Central Otago is related to the distribution and density of rabbits. This intormation can be used as a basis for defining rabbit carrying capacity and consequent land use constraints and management needs. It is concluded that the natural rabbit carrying capacity of land can be defined by reference to soil survey information and cultural modification to the natural vegetation. Classification of land according to rabbit proneness is proposed as a means of identifying the need for, and allocation of, public funding tor rabbit management. Keywords: Rabbit habitat, rabbit proneness, use of rabbit prone land.

Organized crime is spreading like a global virus as mobs take advantage of open borders to establish local franchises at will. That at least is the fear, inspired by stories of Russian mobsters in New York, Chinese triads in London, and Italian mafias throughout the West. As this book explains, the truth is more complicated. The author has spent years researching mafia groups in Italy, Russia, the United States, and China, and argues that mafiosi often find themselves abroad against their will, rather than through a strategic plan to colonize new territories. Once there, they do not always succeed in establishing themselves. The book spells out the conditions that lead to their long-term success, namely sudden market expansion that is neither exploited by local rivals nor blocked by authorities. Ultimately the inability of the state to govern economic transformations gives mafias their opportunity. In a series of matched comparisons, the book charts the attempts of the Calabrese 'Ndrangheta to move to the north of Italy, and shows how the Sicilian mafia expanded to early twentieth-century New York, but failed around the same time to find a niche in Argentina. The book explains why the Russian mafia failed to penetrate Rome but succeeded in Hungary. A pioneering chapter on China examines the challenges that triads from Taiwan and Hong Kong find in branching out to the mainland. This book is both a compelling read and a sober assessment of the risks posed by globalization and immigration for the spread of mafias.
