Gunnar Marklund (5 June 1892 in Helsinki – 23 July 1964 also in Helsinki) was a Finnish botanist (taraxacologist and ranunculologist). Biography Between 1920 and 1941 he worked as a teacher. In 1937 he received his Ph.D. From 1941 to 1959 he was the curator of the Botanical Museum of the University of Helsinki. In 1963, on the occasion of his seventieth birthday, the 38th volume of the ''Memoranda Societatis pro Fauna et Flora Fennica'' was dedicated to him. Scientific work Overview Gunnar Marklund specialised in two difficult apomictic groups, the genus ''Taraxacum'' ( dandelions) and the ''Ranunculus auricomus'' group ( goldilock buttercups). He published four monographs, in which he described about two hundred new species, among them for example ''Ranunculus mendax'' (Markl.) Ericsson, as well as several smaller papers.

University Of Helsinki
The University of Helsinki ( fi, Helsingin yliopisto, sv, Helsingfors universitet, abbreviated UH) is a public research university located in Helsinki, Finland since 1829, but founded in the city of Turku (in Swedish ''Ã…bo'') in 1640 as the Royal Academy of Ã…bo, at that time part of the Swedish Empire. It is the oldest and largest university in Finland with the widest range of disciplines available. In 2020, around 31,600 students were enrolled in the degree programs of the university spread across 11 faculties and 11 research institutes. As of 1 August 2005, the university complies with the harmonized structure of the Europe-wide Bologna Process and offers bachelor, master, licenciate, and doctoral degrees. Admission to degree programmes is usually determined by entrance examinations, in the case of bachelor's degrees, and by prior degree results, in the case of master and postgraduate degrees. Entrance is particularly selective (circa 15% of the yearly applicants are admi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taraxacum
''Taraxacum'' () is a large genus of flowering plants in the family Asteraceae, which consists of species commonly known as dandelions. The scientific and hobby study of the genus is known as taraxacology. The genus is native to Eurasia and North America, but the two most commonplace species worldwide, '' T. officinale'' (the common dandelion) and '' T. erythrospermum'' (the red-seeded dandelion), were introduced from Europe into North America, where they now propagate as wildflowers. Both species are edible in their entirety. The common name ''dandelion'' ( , from French , meaning 'lion's tooth') is also given to specific members of the genus. Like other members of the family Asteraceae, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a ''floret''. In part due to their abundance, along with being a generalist species, dandelions are one of the most vital early spring nectar sources for a wide host ...

Ranunculus Auricomus
''Ranunculus auricomus'', known as goldilocks buttercup or Greenland buttercup, is a perennial species of buttercup native to Eurasia. It is a calcicole typically found in moist woods and at the margins of woods. It is apomictic, and several hundred agamospecies have been recognised. Description ''Ranunculus auricomus'' is a short and slightly hairy perennial herb with bright yellow flowers. It can reach a height between 30–, and have as many as 10 palmately-lobed basal leaves. Its upper stem leaves are deeply divided into 3-5 narrow segments giving the plant a filiform appearance. Its flowers are frequently imperfect or missing, making it difficult to identify ''Ranunculus auricomus'' by flowers alone. Distribution ''Ranunculus auricomus'' is native to northern Europe and western Asia, approximately from latitudes 43 to 71 degrees and from western Ireland to the Ural Mountains. In Britain it is generally a lowland species but has been recorded at on Aonach Beag. It is common ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ã…land Islands
Åland ( fi, Ahvenanmaa: ; ; ) is an autonomous and demilitarised region of Finland since 1920 by a decision of the League of Nations. It is the smallest region of Finland by area and population, with a size of 1,580 km2, and a population of 30,129, constituting 0.51% of its land area and 0.54% of its population. Its only official language is Swedish and the capital city is Mariehamn. Åland is situated in an archipelago, called the Åland Islands, at the entrance to the Gulf of Bothnia in the Baltic Sea belonging to Finland. It comprises Fasta Åland on which 90% of the population resides and about 6,500 skerries and islands to its east. Of Åland's thousands of islands, about 60–80 are inhabited. Fasta Åland is separated from the coast of Roslagen in Sweden by of open water to the west. In the east, the Åland archipelago is contiguous with the Finnish archipelago. Åland's only land border is located on the uninhabited skerry of Märket, which it shares with Swe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1892 Births
Year 189 ( CLXXXIX) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar.
