Russia is the largest country in the world in area. Its almost 6.6 million square miles (17 million sq. km) are spread across two continents—Europe and Asia. As you can imagine, such a large country faces equally large challenges. In 1991 Russia emerged from the Soviet Union as an independent country. Since then it has been struggling to unite its many ethnic groups, set up a demo- cratic government, and build a stable economy. ▼ Siberian tiger in a forest NGS ONLINE in eastern Russia www.nationalgeographic.com/education 225 392-401 U5 CH14 RA TWIP-860976 3/15/04 5:28 AM Page 392 REGIONAL ATLAS Focus on: Russia and the Eurasian Republics THIS REGION spans the continents of Europe and Asia. It includes Russia—the world’s largest country—and the neigh- boring independent republics of Armenia, Georgia, Azerbaijan, Kazakhstan, Uzbekistan, Turkmenistan, Kyrgyzstan, and Tajikistan. Russia and the Eurasian republics cover about 8 million square miles (20.7 million sq. km). This is greater than the size of Canada, the United States, and Mexico combined.

Siberia and the Russian Far East in the 21St Century: Scenarios of the Future
Journal of Siberian Federal University. Humanities & Social Sciences 11 (2017 10) 1669-1686 ~ ~ ~ УДК 332.1:338.1(571) Siberia and the Russian Far East in the 21st Century: Scenarios of the Future Valerii S. Efimov and Alla V. Laptevа* Siberian Federal University 79 Svobodny, Krasnoyarsk, 660041, Russia Received 07.09.2017, received in revised form 07.11.2017, accepted 14.11.2017 The article presents a study of variants of possible future for Siberia and Russian Far East up until 2050. The authors consider the global trends that are likely to determine the situation of Russia and the Siberian macro-region in the long term. It is shown that the demand for natural resources of Siberia and Russian Far East will be determined by the economic development of Asian countries, the processes of urbanization and the growth of urban “middle class”. When determining possible scenarios, the authors use a method of conceptual scenario planning that was developed under the framework of foresight technology. Three groups of scenario factors became the basis for determining scenarios: external constant conditions, external variable factors, internal variable factors. Combinations of scenario factors set the field for the possible variants of the future of Siberia and Russian East. The article describes four key scenarios: “Broad international cooperation”, “Exclusive partnership”, “Optimization of the country”, “Retention of territory”. For each of them the authors provide “the image of the future” (including the main features of international cooperation, economic and social development), as well as the quantitative estimation of population and GDP dynamics: • “Broad international cooperation” – the population of Russia will increase by 15.7 % from 146.5 million in 2015 to 169.5 million in 2050; Russia’s GDP will grow by 3.4 times – from 3.8 trillion dollars (PPP) in 2015 to 12.8 trillion dollars in 2050. -

Archaeology Resources
Archaeology Resources Page Intentionally Left Blank Archaeological Resources Background Archaeological Resources are defined as “any prehistoric or historic district, site, building, structure, or object [including shipwrecks]…Such term includes artifacts, records, and remains which are related to such a district, site, building, structure, or object” (National Historic Preservation Act, Sec. 301 (5) as amended, 16 USC 470w(5)). Archaeological resources are either historic or prehistoric and generally include properties that are 50 years old or older and are any of the following: • Associated with events that have made a significant contribution to the broad patterns of our history • Associated with the lives of persons significant in the past • Embody the distinctive characteristics of a type, period, or method of construction • Represent the work of a master • Possess high artistic values • Present a significant and distinguishable entity whose components may lack individual distinction • Have yielded, or may be likely to yield, information important in history These resources represent the material culture of past generations of a region’s prehistoric and historic inhabitants, and are basic to our understanding of the knowledge, beliefs, art, customs, property systems, and other aspects of the nonmaterial culture. Further, they are subject to National Historic Preservation Act (NHPA) review if they are historic properties, meaning those that are on, or eligible for placement on, the National Register of Historic Places (NRHP). These sites are referred to as historic properties. Section 106 requires agencies to make a reasonable and good faith efforts to identify historic properties. Archaeological resources may be found in the Proposed Project Area both offshore and onshore. -

In: Kahanpää J, Salmela J (Eds) Checklist of the Diptera of Finland. ZooKeys 441: 63–90. doi: 10.3897/zookeys.441.7461 Abstract A checklist of the family Chironomidae (Diptera) recorded from Finland is presented. Keywords Finland, Chironomidae, species list, biodiversity, faunistics Introduction There are supposedly at least 15 000 species of chironomid midges in the world (Armitage et al. 1995, but see Pape et al. 2011) making it the largest family among the aquatic insects. The European chironomid fauna consists of 1262 species (Sæther and Spies 2013). In Finland, 780 species can be found, of which 37 are still undescribed (Paasivirta 2012). The species checklist written by B. Lindeberg on 23.10.1979 (Hackman 1980) included 409 chironomid species. Twenty of those species have been removed from the checklist due to various reasons. The total number of species increased in the 1980s to 570, mainly due to the identification work by me and J. Tuiskunen (Bergman and Jansson 1983, Tuiskunen and Lindeberg 1986). -

The United States has imposed sanctions on Russia mainly in response to Russia’s 2014 invasion of Cory Welt, Coordinator Ukraine, to reverse and deter further Russian aggression in Ukraine, and to deter Russian Specialist in European aggression against other countries. The United States also has imposed sanctions on Russia in Affairs response to (and to deter) election interference and other malicious cyber-enabled activities, human rights abuses, the use of a chemical weapon, weapons proliferation, illicit trade with North Korea, and support to Syria and Venezuela. Most Members of Congress support a robust Kristin Archick Specialist in European use of sanctions amid concerns about Russia’s international behavior and geostrategic intentions. Affairs Sanctions related to Russia’s invasion of Ukraine are based mainly on four executive orders (EOs) that President Obama issued in 2014. That year, Congress also passed and President Rebecca M.

Radar Observations of Arctic Bird Migration in the Beringia Region A
ARCTIC VOL. 62, NO. 1 (MARCH 2009) P. 25–37 Radar Observations of Arctic Bird Migration in the Beringia Region A. HEDENSTRÖM,1 T. ALERSTam,2 J. BÄCKmaN,2 G.A. GUDMUNDSSON,3 S. HENNINGSSON,2 H. KarLSSON,2 M. ROSÉN2 and R. STraNDBErg2 (Received 17 August 2007; accepted in revised form 17 April 2008) ABSTRACT. Bird migration was recorded by tracking radar and visual observations in the Beringia region. The data were subdivided into seven areas extending from north of Wrangel Island southeastward toward the Bering Strait and then northwestward off the coast of Alaska to Point Barrow. The studies, which took place during a ship-based expedition between 30 July and 19 August 2005, recorded a total of 557 tracks (average duration 120 seconds) of bird flocks or individuals on post-breeding migration. The dominant eastward-flying flocks were likely composed of shorebirds on their way from breeding areas in central or eastern Siberia to intermediate stopovers and final destinations inN orth and South America. The courses were more southerly into the Bering Strait, possibly because of topographical influence. At two areas, the Chukchi Sea and Koluch- inskaya Bay, there was also a westward component of migrants. At the Chukchi Sea these were almost certainly passerine birds migrating from Alaska to wintering areas in Asia and Africa, while at Koluchinskaya Bay, king eiders on molt migration could represent an important part of the westward component. The overall mean altitude of flights was 1157 m, and flight altitude was positively correlated with latitude. The mean ground speed was 15.9 m/s and the mean airspeed was 14.1 m/s, indicating that on average the birds were experiencing a small tail wind component. -
