Cryptogramma Crispa
''Cryptogramma crispa'', the parsley fern, is an Arctic–alpine species of fern. It produces separate sterile and fertile fronds, up to tall, and is a pioneer species on acidic screes. Description The fronds of ''C. crispa'' are long and appear in two distinct forms. Sterile leaves are 2–3-pinnate with the pinnules long by wide, while fertile leaves are 3–4-pinnate, and with narrower pinnules. The fertile leaves have sori scattered along the veins, each with a strongly enrolled false indusium. The sporangia are yellow and mature around midsummer. Distribution and ecology ''Cryptogramma crispa'' grows among acidic rocks in areas where snow lies until late in the year. It is a pioneer species on stable scree slopes and also occurs on cliffs and dry stone walls. In Europe, ''C. crispa'' has an Arctic–alpine distribution, growing in the mountains of Central and Southern Europe, as well as in the north of the continent, including Scandinavia and higher ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dry Stone
Dry stone, sometimes called drystack or, in Scotland, drystane, is a building method by which structures are constructed from stones without any mortar to bind them together. Dry stone structures are stable because of their construction method, which is characterized by the presence of a load-bearing façade of carefully selected interlocking stones. Dry stone construction is best known in the context of stone walls, traditionally used for the boundaries of fields and churchyards, or as retaining walls for terracing, but dry stone sculptures, buildings, bridges, and other structures also exist. The term tends not to be used for the many historic styles which used precisely-shaped stone, but did not use mortar, for example the Greek temple and Inca architecture. The art of dry stone walling was inscribed in 2018 on the UNESCO representative list of the intangible cultural heritage of humanity, for dry stone walls in countries such as France, Greece, Italy, Slovenia, Cr ...

Eric Hultén
Oskar Eric Gunnar Hultén (18 March 1894 – 1 February 1981) was a Swedish botanist, plant geographer and 20th century explorer of The Arctic. He was born in Halla in Södermanland. He took his licentiate exam 1931 at Stockholm University and obtained his doctorate degree in botany at Lund University in 1937. In his thesis, he coined the term ''Beringia'' for the ice-age land bridge between Eurasia and North America. From 1945 to 1961, he was a professor and head of the Botany Section at the Swedish Museum of Natural History. In 1953, he was elected to the Royal Swedish Academy of Sciences as member number 977. Hultén travelled extensively in the Scandes Mountains and Siberia, Kamchatka (1920–22 together with his spouse Elsie Hultén, Sten Bergman and René Malaise), the Aleutian Islands and Alaska (1932). He published extensive accounts on the flora of several of these regions and distribution maps of thousands of species. He was the father of the professor of art history ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

East Asia
East Asia is the eastern region of Asia, which is defined in both geographical and ethno-cultural terms. The modern states of East Asia include China, Japan, Mongolia, North Korea, South Korea, and Taiwan. China, North Korea, South Korea and Taiwan are all unrecognised by at least one other East Asian state due to severe ongoing political tensions in the region, specifically the division of Korea and the political status of Taiwan. Hong Kong and Macau, two small coastal quasi-dependent territories located in the south of China, are officially highly autonomous but are under Chinese sovereignty. Japan, Taiwan, South Korea, Mainland China, Hong Kong, and Macau are among the world's largest and most prosperous economies. East Asia borders Siberia and the Russian Far East to the north, Southeast Asia to the south, South Asia to the southwest, and Central Asia to the west. To the east is the Pacific Ocean and to the southeast is Micronesia (a Pacific Ocean island group, classifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harry Godwin
Sir Harry Godwin, FRS (9 May 1901 – 12 August 1985) was a prominent English botanist and ecologist of the 20th century. He is considered to be an influential peatland scientist, who coined the phrase "peat archives" in 1981. He had a long association with Clare College, Cambridge. Early life Godwin was born in Yorkshire and soon after moved to Long Eaton, Derbyshire. He had a successful school career and gained a scholarship to Clare College, Cambridge in 1918, gaining his PhD in 1926. He was to be closely involved with Clare College for the rest of his life. It was at this time that he first made friends with the ecologist Arthur Tansley who was to be an important influence on Godwin for many years. Work In the early 1930s Harry and his wife Margaret were "dynamic botanists" who, together with the archaeologist Grahame Clark, led a small group of young academics at the University of Cambridge which aimed to gain a deeper understanding of the environment of past societies by ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Atlas Florae Europaeae
An atlas is a collection of maps; it is typically a bundle of maps of Earth or of a region of Earth. Atlases have traditionally been bound into book form, but today many atlases are in multimedia formats. In addition to presenting geographic features and political boundaries, many atlases often feature geopolitical, social, religious and economic statistics. They also have information about the map and places in it. Etymology The use of the word "atlas" in a geographical context dates from 1595 when the German-Flemish geographer Gerardus Mercator published ("Atlas or cosmographical meditations upon the creation of the universe and the universe as created"). This title provides Mercator's definition of the word as a description of the creation and form of the whole universe, not simply as a collection of maps. The volume that was published posthumously one year after his death is a wide-ranging text but, as the editions evolved, it became simply a collection of maps and i ...

British Isles
The British Isles are a group of islands in the North Atlantic Ocean off the north-western coast of continental Europe, consisting of the islands of Great Britain, Ireland, the Isle of Man, the Inner and Outer Hebrides, the Northern Isles, and over six thousand smaller islands."British Isles", ''Encyclopædia Britannica''. They have a total area of and a combined population of almost 72 million, and include two sovereign states, the Republic of Ireland (which covers roughly five-sixths of Ireland), and the United Kingdom of Great Britain and Northern Ireland. The Channel Islands, off the north coast of France, are normally taken to be part of the British Isles, even though they do not form part of the archipelago. The oldest rocks are 2.7 billion years old and are found in Ireland, Wales and the northwest of Scotland. During the Silurian period, the north-western regions collided with the south-east, which had been part of a separate continental landmass. The ...

Scandinavia
Scandinavia; Sámi languages: /. ( ) is a subregion#Europe, subregion in Northern Europe, with strong historical, cultural, and linguistic ties between its constituent peoples. In English usage, ''Scandinavia'' most commonly refers to Denmark, Norway, and Sweden. It can sometimes also refer more narrowly to the Scandinavian Peninsula (which excludes Denmark but includes part of Finland), or more broadly to include all of Finland, Iceland, and the Faroe Islands.
