Bloodlands
Bloodlands: Europe Between Hitler and Stalin is a book by Yale historian Timothy D. Snyder that was first published by Basic Books on October 28, 2010. In the book, Snyder examines the political, cultural and ideological context tied to a specific region of Central and Eastern Europe, where Joseph Stalin 's Soviet Union and Adolf Hitler's Nazi Germany committed mass killings of an estimated 14 million noncombatants between 1933 and 1945, the majority outside the death camps of the Holocaust. Snyder's thesis is that the "bloodlands", a region that is now Poland , Belarus , Ukraine , the Baltic states (Estonia, Latvia, and Lithuania), northeastern Romania, and the westernmost fringes of Russia , is the area that the regimes of Stalin and Hitler, despite their conflicting goals, interacted to increase suffering and bloodshed many times worse than any seen in western history. Snyder notes similarities between the two totalitarian regimes and also the enabling interactions that reinforced the destruction and the suffering that were brought to bear on noncombatants. Making use of many new primary and secondary sources from Central and Eastern Europe, Snyder brings scholarship to many forgotten, misunderstood, or incorrectly-remembered parts of the history, and he particularly notes that most of the victims were killed outside the concentration camps of the respective regimes. The book earned many positive reviews and has been called "revisionist history of the best kind". It was awarded numerous prizes, including the 2013 Hannah Arendt Prize for Political Thought.

Maritime Southeast Asia
Maritime Southeast Asia comprises the countries of Brunei, East Timor, Indonesia, Malaysia, the Philippines and Singapore. Maritime Southeast Asia is sometimes also referred to as Island Southeast Asia, Insular Southeast Asia or Oceanic Southeast Asia. The 16th-century term "East Indies" and the later 19th-century term "Malay Archipelago" are also used to refer to Maritime Southeast Asia. In Indonesia and Malaysia, the Old Javanese term "Nusantara" is also used as a synonym for Maritime Southeast Asia. The term, however, is nationalistic and has shifting boundaries. It usually only encompasses the Malay Peninsula, the Sunda Islands, Maluku, and often Western New Guinea and excludes the Philippines . Stretching for several thousand kilometres, the area features a very large number of islands and boasts some of the richest marine, flora and fauna biodiversity on Earth. The main demographic difference that sets Maritime Southeast Asia apart from modern Mainland Southeast Asia is that its population predominantly belongs to Austronesian groups. The region contains some of the world's most highly urbanized areas—Greater Jakarta, Greater Kuala Lumpur, Metro Manila, and Singapore—and yet a majority of islands in this vast region remain uninhabited by humans.

Reindeer Distribution
The reindeer is a widespread and numerous species in the northern Holarctic, being present in both tundra and taiga (boreal forest). Originally, the reindeer was found in Scandinavia, eastern Europe, Russia , Mongolia, and northern China north of the 50th latitude. In North America, it was found in Canada , Alaska (United States ), and the northern contiguous USA from Washington to Maine. In the 19th century, it was apparently still present in southern Idaho. It also occurred naturally on Sakhalin, Greenland, and probably even in historical times in Ireland. During the late Pleistocene era, reindeer were found further south, such as at Nevada, Tennessee , and Alabama in North America and Spain in Europe. Today, wild reindeer have disappeared from many areas within this large historical range, especially from the southern parts, where it vanished almost everywhere. Populations of wild reindeer are still found in Norway , Finland , Siberia, Greenland, Alaska, and Canada . Domesticated reindeer are mostly found in northern Fennoscandia and Russia, with a herd of approximately 150–170 semi-domesticated reindeer living around the Cairngorms region in Scotland. The last remaining wild tundra reindeer in Europe are found in portions of southern Norway . A few reindeer from Norway were introduced to the South Atlantic island of South Georgia in the beginning of the 20th century. The South Georgian reindeer totaled some estimated 2600 animals in two distinct herds separated by glaciers. Although the flag and the coat of arms of the territory contain an image of a reindeer, they were eradicated from 2013 to 2017 because of the environmental damage they caused. Around 4000 reindeer have been introduced into the French sub-Antarctic archipelago of Kerguelen Islands. East Iceland has a small herd of about 2500–3000 animals. Caribou and reindeer numbers have fluctuated historically, but many herds are in decline across their range. This global decline is linked to climate change for northern, migratory caribou and reindeer herds and industrial disturbance of caribou habitat for sedentary, non-migratory herds.

Ecological Effects of Biodiversity
The diversity of species and genes in ecological communities affects the functioning of these communities. These ecological effects of biodiversity in turn are affected by both climate change through enhanced greenhouse gases, aerosols and loss of land cover, and biological diversity, causing a rapid loss of biodiversity and extinctions of species and local populations. The current rate of extinction is sometimes considered a mass extinction, with current species extinction rates on the order of 100 to 1000 times as high as in the past. The two main areas where the effect of biodiversity on ecosystem function have been studied are the relationship between diversity and productivity, and the relationship between diversity and community stability. More biologically diverse communities appear to be more productive (in terms of biomass production) than are less diverse communities, and they appear to be more stable in the face of perturbations. Also animals that inhabit an area may alter the surviving conditions by factors assimilated by climate.

Black Sea Climate and Ecology
Short-term climatic variation in the Black Sea region is significantly influenced by the operation of the North Atlantic oscillation, the climatic mechanisms resulting from the interaction between the north Atlantic and mid-latitude air masses. While the exact mechanisms causing the North Atlantic Oscillation remain unclear, it is thought the climate conditions established in western Europe mediate the heat and precipitation fluxes reaching Central Europe and Eurasia, regulating the formation of winter cyclones, which are largely responsible for regional precipitation inputs and influence Mediterranean Sea surface temperatures (SST's). The relative strength of these systems also limits the amount of cold air arriving from northern regions during winter. Other influencing factors include the regional topography, as depressions and storms systems arriving from the Mediterranean are funneled through the low land around the Bosporus, Pontic and Caucasus mountain ranges acting as waveguides, limiting the speed and paths of cyclones passing through the region.

Restrictions on Geographic Data in China
Due to national security concerns, the use of geographic information in China is restricted to entities that obtain a special authorization from the administrative department for surveying and mapping under the State Council. Consequences of the restriction include fines for unauthorized surveys, lack of geotagging information on many cameras when the GPS chip detects a location within China, incorrect alignment of street maps with satellite maps in various applications, and seeming unlawfulness of crowdsourced mapping efforts such as OpenStreetMap.

Mekong
The Mekong, or Mekong River, is a trans-boundary river in East Asia and Southeast Asia. It is the world's twelfth longest river and the sixth longest in Asia. Its estimated length is 4,909 km (3,050 mi), and it drains an area of 795,000 km2 (307,000 sq mi), discharging 475 km3 (114 cu mi) of water annually. From the Tibetan Plateau the river runs through China , Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia.

Canopy
In biology, the canopy is the aboveground portion of a plant cropping or crop, formed by the collection of individual plant crowns. In forest ecology, canopy also refers to the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, resilience, and functioning. Sometimes the term canopy is used to refer to the extent of the outer layer of leaves of an individual tree or group of trees. Shade trees normally have a dense canopy that blocks light from lower growing plants.

Mobile Local Search
Mobile local search is a technology that lets people search for local things using mobile equipment such as mobile phones, PDAs, and other mobile devices. Mobile local search satisfies the need to offer a mobile subscriber spontaneous access to near-position services and information such as businesses, products, events, restaurant, movie theatre or other local information. Mobile local search is the search and discovery of persons, places, and things within an identifiable space defined by distinct parameters. These parameters are evolving. Today they include social networks, individuals, cities, neighborhoods, landmarks, and actions that are relevant to the searcher's past, current, and future location. These parameters provide structure to vertically deep and horizontally broad data categories that can stand-alone or are combined to comprise searchable directories. Mobile local search is usually based on organized directories accessed through specialized search tools, rather than the web, although mobile local search often provides links to mobile (WAP) web sites. It is also an application of a location-based service.
