Abstract I. rugosum is a C4 grass species widely cultivated and naturalized in moist, tropical habitats around the world (Clayton et al., 2015; USDA-ARS, 2015). It is an opportunistic and effective colonizer of open and disturbed areas, swamps, and along roadsides. It is a serious weed in many crops, especially in paddy fields and sugarcane plantations (Holm et al., 1977; Baki and Manidool, 1992). I. rugosum is a highly invasive grass which can produce up to 4,000 seeds per plant and has the potential to grow even in shaded areas (Holm et al., 1977; PROTA, 2015). I. rugosum is listed as invasive in Costa Rica, Cuba, the Dominican Republic and Fiji (Kairo et al., 2003; Chacon and Saborio, 2012; Oviedo Prieto et al., 2012; PIER, 2015). In the USA, the Department of Agriculture considers it a noxious weed; plants found growing within the continental USA should be promptly reported to that agency (Barkworth et al., 2003).

Abstract Producing large quantities of seeds, D. aegyptium is a pioneer grass that quickly colonizes disturbed areas with light sandy soils, often near to coasts or where water accumulates. It is a common component of weed floras throughout the tropics but is rarely reported as an aggressive weed on its own. It is not on federal or state noxious weed lists in the USA and is not recorded on the ISSG database but is recorded by PIER (2016) as invasive on a number of Pacific and American islands including French Polynesia Islands, Micronesia, the Northern Mariana Islands and Hawaii. It is also listed as invasive on islands in the Mediterranean, the USA, Mexico, Costa Rica, Puerto Rico, Virgin Islands and the Lesser Antilles (Vibrans, 2009; Florida Exotic Pest Plant Council, 2011;Chacón and Saborío, 2012; Burg et al., 2012; Rojas-Sandoval and Acevedo-Rodríguez, 2015; DAISIE, 2016; USDA-NRCS, 2016).

Abstract H. verticillata is a submerged fast-growing aquatic herb. It has a highly effective survival strategy that makes it one of the most troublesome aquatic weeds of water bodies in the world. It has the potential to alter fishery populations, cause shifts in zooplankton communities and affect water chemistry. It forms dense masses, outcompeting native plants and interfering with many uses of waterways. It is readily dispersed by movement of plant fragments and can produce up to 6,000 tubers per m2. Tubers can remain viable for several days out of water or for over 4 years in undisturbed sediment. They are not impacted by most management activities, and a small percentage can sprout throughout the year making the species very difficult to manage or eradicate. It can be spread by water flow, waterfowl and recreational activities and is sold as an aquarium plant. Currently, this species is considered as one of the most aggressive invasive species in aquatic habitats. In the USA it has been listed as a Federal Noxious Weed since 1976, and is regarded as one of the worst invasive aquatic weed problems in Florida and much of the country. Its import is prohibited in Western Australia and Tasmania, and it is on the EPPO alert list.

Abstract Lupinus plattensis is a fast-growing, perennial herb native to the USA. It can be weedy or invasive primarily in disturbed and ruderal areas, within and outside its native distribution range. The species spreads both by seed and vegetatively by rootstocks, and has the potential to rapidly colonize disturbed areas. Currently, it is listed as invasive only in the Dominican Republic, although no specific impacts have been recorded.

Abstract E. ophiuroides is a perennial grass that has been intentionally introduced into tropical and warm temperate areas to be used as a lawn grass (USDA-ARS, 2016). In the United States it has become a common lawn grass principally in the southeastern states (Brosnan and Deputy, 2008; Duble, 2016). However, in the USA, it also behaves as a weed principally in disturbed sites and along roadsides (Coile, 1993; USDA-NRCS, 2016) and Miller et al. (2010) recently reported that it is invading natural and disturbed areas across the southern states. It is also listed as an invasive grass in Puerto Rico (Rojas-Sandoval and Acevedo-Rodríguez, 2015). E. ophiuroides spreads easily by seeds and by stolons and grows forming dense mats of prostrate, low-growing stems and leaves (Brosnan and Deputy, 2008). Plants also recover quickly after fire (Walsh, 1994).

The number of classical banks in the world has reduced. In the majority of countries the number of banks does not exceed 200. The uniqueness of the Russian banking sector is that in this respect it takes the third place in the world after the USA and Germany. The paper reviews the conclusions of the economic theory about the optimum structure of the banking market. The empirical analysis shows that the number of banks in a country is influenced by the size of its territory, population number and GDP per capita. Our econometric estimate is that the equilibrium number of banks in Russia should be in a range of 180-220 units.

The authors point out that the local market crisis - on the USA substandard loan market - has led to the uncertainty of the world financial market. It has caused the growing demand for liquidity in the framework of the world financial system. The Russian banking sector seems to be more stable under negative changes than banking systems of other emerging markets. At the same time one can assume that the crisis will become the factor of qualitative shift in the character of the Russian banking sector development - the shift from impetuous to more balanced growth.

Authors from the Christian Right in the USA situate the September 11 attack on New York and Washington within God's intentions to bring America into the divine schedule for the end of the world. This is true of Pat Robertson and Jerry Falwell, and other leading figures in the ‘Christian Coalition’. This article analyses how Christian fundamentalists assess the roles of the USA, the State of Israel, Islam, Iraq, the European Union and Russia within what they perceive to be the divine plan for the future of the world, especially against the background of ‘9/11’. It argues that the ideas of the Christian Right and of President George W. Bush coalesce to a high degree. Whereas before 9/11 many American mega-church preachers had aspirations to direct political life, after the events of that day the President assumes some of the roles of a mega-religious leader.

Sandra Ramos (b. 1969) is one of the few artists to reflect critically on both sides of the Cuban di-lemma, fully embodying the etymological origins of the word in ancient Greek: di-, meaning twice, and lemma, denoting a form of argument involving a choice between equally unfavorable alternatives. Throughout her works she shines a light on the dilemmas faced by Cubans whether in Cuba or the United States, underlining the bad personal and political choices people face in both countries. During the hard 1990s, while still in Havana, the artist focused on the traumatic one-way journey into exile by thousands, as well as the experience of profound abandonment experienced by those who were left behind on the island. Today she lives in Miami and operates a studio there as well as one in Havana. Her initial disorientation in the USA has morphed into an acerbic representation and critique of the current administration and a deep concern with the environmental collapse we face. A buffoonlike Trumpito has joined el Bobo de Abela and Liborio in her gallery of comic characters derived from the rich Cuban graphic arts tradition where she was formed. While Cuba is now represented as a rotten cake with menacing flies hovering over it ready to pounce, a bombastic Trumpito marches across the world stage, trampling everything underfoot, a dollar sign for a face.

The paper summarizes information on chromosome numbers (CNs) of the Grass species (Poaceae) in the flora of Russian Federation, obtained on the original material, most part - from the Russian Far East (RFE). In some species the CNs are known in Russia or in the world only from RFE, in some – from one locality or few, or from one subregion of RFE. The grass species in RFE often occur in mountain regions and near seacoasts; some species are endemics, some were studied near the limits of their geographical distribution areas. The diversity of CNs, the special features of the CNs distribution in some grass groups are discussed. The alien species are abundant in RFE, and their CNs are also involved in the study. For karyologically polymorphous species further studies are needed.
