Vätsäri Wilderness Area
The Vätsäri Wilderness Area (, ) is located along the northeastern shore of Lake Inari in Inari, northern Finland, stretching all the way to the Finland–Norway border. The landscape is dominated by taiga forests of Scots pine, bog and bodies of water. The northeastern part rises as a treeless fell ridge. Vätsäri is one of twelve wilderness areas in Lapland and covers an area of . The wilderness has one marked trail and a few cabins. The reserve is under the management of Metsähallitus (Administration of Forests) and was established with the other wilderness reserves in 1991. It is part of Pasvik–Inari Trilateral Park along with Øvre Pasvik National Park and Øvre Pasvik Landscape Protection Area in Norway, and the joint Norwegian–Russian Pasvik Nature Reserve. The area has a short growing season, cold winters, little precipitation and poor soil quality created by the gneiss bedrock. Lake Inari has been affected by acid rain and loss of fish from the Paatsjoki Riv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lapland (Finland)
Lapland is the largest and northernmost region of Finland. The 21 municipalities in the region cooperate in a Regional Council. Lapland borders the Finnish region of North Ostrobothnia in the south. It also borders the Gulf of Bothnia, Norrbotten County in Sweden, Finnmark County and Troms County in Norway, and Murmansk Oblast and the Republic of Karelia in Russia. The topography of Lapland varies from vast mires and forests in the south to fells in the north. The Arctic Circle crosses Lapland, so polar phenomena such as the midnight sun and polar night can be viewed in this region. Lapland's cold and wintry climate, coupled with its relative abundance of conifer trees such as pines and spruces, means that it has become associated with Christmas in some countries, most notably the United Kingdom, and holidays to Lapland are common towards the end of the year. However, the Lapland region has developed its infrastructure for year-round tourism. For example, in 2019, tour ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acid Rain
Acid rain is rain or any other form of Precipitation (meteorology), precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH). Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average. The more acidic the acid rain is, the lower its pH is. Acid rain can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the Properties of water, water molecules in the atmosphere to produce acids. Acid rain has been shown to have adverse impacts on forests, Fresh water, freshwaters, soils, microbes, insects and aquatic life-forms. In ecosystems, persistent acid rain reduces tree bark durability, leaving flora more susceptible to environmental stressors such as drought, heat/cold and pest infestation. Acid rain is also capable of detriment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Rock
Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "pyroclastics," and these are also technically sedimentary rocks. Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated that volcanic rocks cover about 8% of the Earth's current land surface. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slate
Slate is a fine-grained, foliated, homogeneous, metamorphic rock derived from an original shale-type sedimentary rock composed of clay or volcanic ash through low-grade, regional metamorphism. It is the finest-grained foliated metamorphic rock. Foliation may not correspond to the original sedimentary layering, but instead is in planes perpendicular to the direction of metamorphic compression. The foliation in slate, called " slaty cleavage", is caused by strong compression in which fine-grained clay forms flakes to regrow in planes perpendicular to the compression. When expertly "cut" by striking parallel to the foliation with a specialized tool in the quarry, many slates display a property called fissility, forming smooth, flat sheets of stone which have long been used for roofing, floor tiles, and other purposes. Slate is frequently grey in color, especially when seen ''en masse'' covering roofs. However, slate occurs in a variety of colors even from a single locality; for ...

Pasvik River
The Paatsjoki River (, , , , , , ''Paz or Patsoyoki'') is a river that flows through Finland, Norway, and Russia. Since 1826, the river has marked parts of the Norway–Russia border, except from 1920 to 1944 when it was along the Finland–Norway border. The river is the outlet from the large Lake Inari in Finland and flows through Norway and Russia to discharge into the Bøkfjorden (which later flows into the Varangerfjorden and then the Barents Sea), not far from the town of Kirkenes. The river has a watershed of , and is long. A series of hydroelectric stations, known as the Paatsjoki River Hydroelectric Plants, are along the river. Five of those sevenhttps://www.dagsavisen.no/nyheter/2023/12/03/samarbeid-med-russland-lagt-pa-is-et-tap/. Dagsavisen.no. Retrieved 2023-12-04 power stations, are Russian.

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coregonus Albula
''Coregonus albula'', known as the vendace or as the European cisco, is a species of freshwater whitefish in the family Salmonidae. It is found in lakes in northern Europe, especially Finland, Latvia, Lithuania, Sweden, Russia and Estonia, and in some lakes of Norway, the United Kingdom, northern Germany, and Poland. It is also found in diluted brackish water in the Gulfs of Finland and Bothnia, both of which are in the Baltic Sea. The length of an adult is normally about . The maximum age is about ten years. The vendace is traditionally the most important target of freshwater fisheries in parts of Fennoscandia and Russia. Vendace roe is considered a delicacy, which has been granted a PDO status in the Swedish Bothnian Bay archipelago ( Kalix löjrom). Description The vendace is a slim and streamlined fish with an adipose fin - an additional small fin on the back between the dorsal fin and the tail (caudal fin) which is typical in the salmon family. Its lower jaw is longer t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coregonus Lavaretus
''Coregonus lavaretus'' is a species of freshwater whitefish, in the family Salmonidae. It is the type species of its genus '' Coregonus''. There are widely different concepts about the delimitation of the species ''Coregonus lavaretus'' and about the number of species in the genus ''Coregonus'' in general. Lavaret In a narrow sense, ''Coregonus lavaretus'', or the lavaret, is considered to be endemic to Lake Bourget and Lake d'Aiguebelette in the Rhône river basin in France, whereas it formerly also occurred in Lake Geneva. According to this view there is a great number of distinct whitefish species in lakes, rivers and brackish waters of Central and Northern Europe. European whitefish (common whitefish) In the broad sense, ''Coregonus lavaretus'', in English referred to as the common whitefish or European whitefish, is widespread from central and northwest Europe to Siberia. Often called the ''C. lavaretus'' complex and considered as a superspecies, it encompasses many o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reindeer Husbandry
Reindeer herding is when reindeer are herded by people in a limited area. Currently, reindeer are the only semi-domesticated animal which naturally belong to the North. Reindeer herding is conducted in nine countries: Norway, Finland, Sweden, Russia, Greenland, The United States (Alaska), Mongolia, China and Canada. A small herd is also maintained in Scotland's Cairngorms National Park. Reindeer herding is conducted by individuals within some kind of cooperation, in forms such as families, districts, Sámi and Yakut villages and sovkhozy (collective farms). A person who conducts reindeer herding is called a reindeer herder and approximately 100,000 people are engaged in reindeer herding today around the circumpolar North. Domestication The domestication of the reindeer does not lend itself to a simple explanation. There is no doubt that when the glaciers retreated at the end of the last Ice Age, people followed reindeer to the North, using traps during the reindeer hunt. Modern ...
