Edmund Russow
Edmund August Friedrich Russow (russian: Эдму́нд Фридрихович Ру́ссов, translit=Èdmúnd Fridrichovič Rússov; – ) was a Baltic German biologist. Academic career Son of a military engineer, Edmund Russow studied at the Universities of Dorpat (now Tartu, Tartu County, Estonia) and Berlin. In 1867 he became an associate professor at Dorpat, where from 1874 to 1897, he served as a full professor. In 1895-97 he was president of the Estonian Naturalists' Society. Russow was at the forefront of nature conservation in Estonia, and associated with the work of Hugo Conwentz (1865-1922), a founder of nature conservation efforts throughout Europe. Botanical work Russow was an authority on Sphagnaceae ( sphagnum mosses) and remembered for his research in plant anatomy and histology, in particular studies of the plant family Marsileaceae (aquatic and semi-aquatic ferns). The plant genus ''Russowia'' is named in his honor, as is ''Sphagnum russowii'' ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reval
Tallinn () is the most populous and capital city of Estonia. Situated on a bay in north Estonia, on the shore of the Gulf of Finland of the Baltic Sea, Tallinn has a population of 437,811 (as of 2022) and administratively lies in the Harju ''maakond'' (county). Tallinn is the main financial, industrial, and cultural centre of Estonia. It is located northwest of the country's second largest city Tartu, however only south of Helsinki, Finland, also west of Saint Petersburg, Russia, north of Riga, Latvia, and east of Stockholm, Sweden. From the 13th century until the first half of the 20th century, Tallinn was known in most of the world by variants of its other historical name Reval. Tallinn received Lübeck city rights in 1248,, however the earliest evidence of human population in the area dates back nearly 5,000 years. The medieval indigenous population of what is now Tallinn and northern Estonia was one of the last "pagan" civilisations in Europe to adopt Christianity fol ...

People From The Governorate Of Estonia
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

Fern
A fern (Polypodiopsida or Polypodiophyta ) is a member of a group of vascular plants (plants with xylem and phloem) that reproduce via spores and have neither seeds nor flowers. The polypodiophytes include all living pteridophytes except the lycopods, and differ from mosses and other bryophytes by being vascular, i.e., having specialized tissues that conduct water and nutrients and in having life cycles in which the branched sporophyte is the dominant phase. Ferns have complex leaves called megaphylls, that are more complex than the microphylls of clubmosses. Most ferns are leptosporangiate ferns. They produce coiled fiddleheads that uncoil and expand into fronds. The group includes about 10,560 known extant species. Ferns are defined here in the broad sense, being all of the Polypodiopsida, comprising both the leptosporangiate (Polypodiidae) and eusporangiate ferns, the latter group including horsetails, whisk ferns, marattioid ferns, and ophioglossoid ferns. Ferns first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marsileaceae
Marsileaceae () is a small family of heterosporous aquatic and semi-aquatic ferns, though at first sight they do not physically resemble other ferns. The group is commonly known as the "pepperwort family" or as the "water-clover family" because the leaves of the genus ''Marsilea'' superficially resemble the leaves of a four-leaf clover. In all, the family contains 3 genera and 50 to 80 species with most of those belonging to ''Marsilea''. Natural history Members of the Marsileaceae are aquatic or semi-aquatic. Plants often grow in dense clumps in mud along the shores of ponds or streams, or they may grow submerged in shallow water with some of the leaves extending to float on the water surface. They grow in seasonally wet habitats, but survive the winter or dry season by losing their leaves and producing hard, desiccation-resistant reproductive structures. There are only three living genera in the family Marsileaceae. The majority of species (about 45 to 70) belong to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
