The changes already evident in the Arctic, such as the cyclonic shift in the distribution of Atlantic and Pacific water masses, atmospheric pressure and winds, as well as the thinning and retreat of the sea ice, will be felt first and most dramatically around the circum-Arctic shelves, which comprise nearly 50% of the area of the Arctic Ocean. The Scandinavian ice sheet, the centre of which is situated in the Scandinavian mountain range, covered Finland and the northwestern Russian Plain several times during the Quaternary cold is not known precisely how many times Finland and adjacent areas were covered by ice during the Quaternary. This is because the area is situated close to the glaciation centre, and the ice-advances.
the present-day distribution of cold environments; Cold Environments in the past. About years ago, much of the Northern Hemisphere was plunged into an ice age. In the UK, only southern Britain escaped being covered by ice. Scientists believe that this was one of as many as 20 glacial periods – each one separated by a warmerinter-glacial. Finland's total area is , km 2 (, sq mi). Of this area 10% is water, 69% forest, 8% cultivated land and 13% other. Finland is the eighth largest country in Europe after Russia, France, Ukraine, Spain, Sweden, Norway and Germany. As a whole, the shape of Finland's boundaries resembles a figure of a one-armed human.
Glacial landform - Glacial landform - Glacial deposition: Debris in the glacial environment may be deposited directly by the ice (till) or, after reworking, by meltwater streams (outwash). The resulting deposits are termed glacial drift. As the ice in a valley glacier moves from the area of accumulation to that of ablation, it acts like a conveyor belt, transporting debris located beneath.

The Karelian ASSR lies adjacent to the border of Finland and includes 2 concentric ice margin belts in addition to many other glacial features arranged in a broadly radial : Risto Väinölä.

Societas Scientiarum Fennica (Commentationes. Abstract Saduria entomon (Linnaeus, ) is a glacial relict with a distribution restricted to the Baltic Sea and several lakes in the Scandinavian region. It is also mentioned in arctic shallow.
This species which has a wide circumpolar distribution occurs as a glacial relict in the Baltic Sea. In contrast with P. affinis, it does not tolerate strong dilution of the water (limit at about 6 %o) and in the Baltic is absent, therefore, from large parts of the Gulf of Bothnia and the Gulf of Finland, as well as from the upper, less saline Cited by: Distribution and hotspot of Cenozoic relict plants.
Figure 3 shows the number of Cenozoic relict genera present in each county. The counties with high numbers of relict genera are situated mainly at the border of Chongqing and Hubei, those of Hunan, Guangxi and Guangdong provinces, and the Tibetan margin of Sichuan (Fig.
3a).The county with the highest number of relict genera is Nanchuan in Cited by: Cenozoic plant relicts are those groups that were once widespread in the Northern Hemisphere but are now restricted to some small isolated areas as a. Distribution of Cenozoic plant relicts in China explained by drought in dry season and adjacent areas remain poorly understood.

The acanthocephalan parasites of seals, Corynosoma strumosum (Rud.) and C. semerne (Forssell) were found in one mink farm in the south western archipelago of Finland, where the minks suffered from a bloody and often fatal diarrhoeal anaemia.
strumosum was found in the two victims of the disease examined, whereas C. semerne occurred in 753 per cent of the surviving minks. Challenging the generally accepted view of the fourhorn sculpin Triglopsis quadricornis as a cold-stenothermal and true benthic species, novel findings of juveniles in the pelagic habitat of Lake Vättern, Sweden, have been examined and critically evaluated.
Young-of-the-year and small-sized, sexually mature individuals, ranging 27–45 and 82– mm in total length, were recorded in. of the last glaciation, glacial landforms and relicts are rather well preserved in the high mountains of subtropical Taiwan.
Cirque glaciers and rectilinear trough valleys are distinctive glacial landforms in the Hseuhshan (m) and the Nanhutashan (m) area, respectively, in north-central Taiwan. The geology of Finland is made up of a mix of geologically very young and very old materials. Common rock types are orthogneiss, granite, metavolcanics and metasedimentary rocks.
On top of these lies is a widespread thin layer of unconsolidated deposits formed in connection to the Quaternary ice ages, for example eskers, till and marine topographic relief is rather subdued because.
Mysid crustaceans of the Mysis relictaspecies group are widespread throughout the northern Holarctic and play an important role in many fresh- and brackish-water ecosystems. Earlier molecular and. taxa are largely glacial relicts from the last glacial times.
Most of endemics and semi-endemics derive from European species, are differentiated at the species level and should be linked to older immigration waves induced by former glacial times.
There is a strong difference in the representation of the Afrotropical and European fauna from a. Glacial relicts have been regionally more common in glacial than in recent times.
A rigorous assessment of which species are indeed glacial relicts is extremely difficult because direct evidence is untraceable or equivocal for many species. We aimed to identify species of the Western Carpathian flora (vascular plants, bryophytes and terrestrial lichens) that display apparent biogeographical.
Two glacial relicts, Saxifraga paniculata Mill. and Draba aizoides L., were quantitatively surveyed on 28 cliffs in to investigate their occurrence compared to former surveys and to analyse.
The identification of climatic relicts is seldom straightforward. These species are threatened owing to current climatic trends, which underlines the importance of carrying out ecological and biogeographic investigations of them.
Here we introduce a novel approach to improve the identification of climatic relicts. We are focusing on thermophilic relict plants of the Pannonian biogeographic. The History of Finland begins around 9, BC during the end of the last glacial period.
Stone Age cultures were Kunda, Comb Ceramic, Corded Ware, Kiukainen, and Pöljä cultures. The Finnish Bronze Age started in approximately 1, BC and the Iron Age started in BC and lasted until 1, AD. Finnish Iron Age cultures can be separated into Finnish proper, Tavastian, and Karelian cultures.
All of Finland was covered by ice during the Saalian Stage glaciation (e.g. Svendsen et al., ) although little is known about the Saalian glacial history of Finland. However, there are a number of sites, particularly in Lapland and central western Finland, where till or glaciofluvial deposits underlie Eemian organic sediments (cf.

Eutrophication, habitat modification and alien species are in the list of the main threats to the ecological integrity of the coastal ecosystems worldwide and in the Baltic Sea, in particular (Cloern,Schernewski and Schiewer,UNEP, ).The Neva Estuary situated in the eastern part of the Gulf of Finland (), is one of the largest estuaries of the Baltic Sea.However some birds remained finding suitable conditions in mountainous areas such as the Carpathians, Alps and others.
These populations soon became rather fragmented, with some such as on Mount Olympos in Greece, becoming highly isolated. Thus, southern populations of Three-toed Woodpeckers are glacial relicts.C. Pérez-Rodrigo, J. Aranceta, in Encyclopedia of Food and Health, Olive Cultivation and Varieties.
Wild olive tree is known as ‘acebuche’ (Olea sylvestris).It was one of the first varieties of olive trees in the Mediterranean area and after several crosses and upgrades originated the existing variety Olea europaea.
Olive trees are grown in warm, dry climates and olive harvest is.
