Heinrich Sandstede
Johann Heinrich Sandstede (10 March 1859 – 5 March 1951) was a German lichenologist and local historian who contributed to the study of lichens, particularly the genus ''Cladonia''. Born in Bad Zwischenahn, Oldenburg, Sandstede initially worked as a baker before dedicating his career to botany and lichenology. He published extensive research on the lichen funga of Northwest Germany and the Frisian Islands, including a notable work on ''Cladonia'' in the ''Rabenhorst'' series. Sandstede's contributions to lichenology earned him recognition from scientific societies and an honorary doctorate from the University of Münster. Beyond his scientific work, he was active in preserving local history and folklore, contributing to the founding of the Freiland Museum and publishing on regional customs. Sandstede's dual interests in lichenology and local culture made him a significant figure in both scientific and cultural spheres of early 20th-century Germany. Early life and education ...

Bad Zwischenahn
Bad Zwischenahn (; ) is a town and a municipality in the low-lying Ammerland district, in Lower Saxony, Germany. It is on Zwischenahner Meer, approximately 15 km northwest of Oldenburg and about 70 km south of the North Sea coast. History The first written evidence of Zwischenahn dates back to 1124 in connection with the founding of St. John's Church by Count Egilmar of Oldenburg. During the Nazi era, Bad Zwischenahn was one of the Nazi strongholds in Ammerland and the whole of Emsland. During World War II Bad Zwischenahn was home to the largest Luftwaffe airbase in northern Germany, the 'Adlerhorst' military airport in Rostrup (Bad Zwischenahn). From here, Luftwaffe pilots flew their attacks on the Netherlands and Great Britain from May 10, 1940. Since 1943, the airport was home of the Erprobungskommando 16 service-test unit, then Jagdgeschwader 400 each in their turn operating the Messerschmitt Me 163 Komet rocket fighter from the base. The airbase was heavily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liverworts
Liverworts are a group of non-vascular plant, non-vascular embryophyte, land plants forming the division Marchantiophyta (). They may also be referred to as hepatics. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. The division name was derived from the genus name ''Marchantia'', named after his father by French botanist Jean Marchant. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (botany), costa (present in many mosses) and may bear marginal cilia (botany), cilia (very rare i ...

Exsiccata
Exsiccata (Latin, ''gen.'' -ae, ''plur.'' -ae) is a work with "published, uniform, numbered set[s] of preserved specimens distributed with printed labels". Typically, exsiccatae are numbered collections of dried herbarium Biological specimen, specimens or preserved biological sample (material), samples published in several duplicate sets with a common theme or title, such as ''Lichenes Helvetici exsiccati'' (see figure). Exsiccatae are regarded as scientific contributions of the editor(s) with characteristics from the library world (published booklets of scientific literature, with authors/ editing, editors, titles, often published in Serial (publishing), serial publications like journals and magazines and in Serial_(literature), serial formats with fascicles) and features from the herbarium world (uniform and numbered collections of duplicate herbarium specimens). Exsiccatae works represent a special method of scholarly communication. The text in the printed matters/published book ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edvard August Vainio
Edvard August Vainio (born Edvard Lang; 5 August 185314 May 1929) was a Finnish lichenology, lichenologist. His early works on the lichens of Lapland (Finland), Lapland, his three-volume monograph on the lichen genus ''Cladonia'', and, in particular, his study of the taxonomy (biology), classification and morphology (biology), form and structure of lichens in Brazil, made Vainio renowned internationally in the field of lichenology. Young Vainio's friendship with university student Johan Petter Norrlin, who was nearly eleven years older, helped him develop an impressive knowledge of the local cryptogams (ferns, mosses, algae, and fungi, including lichens) and afforded him ample opportunity to hone his collection and identification (biology), identification techniques at an early age. It was through this association that Vainio met Norrlin's teacher, the prominent lichenologist William Nylander (botanist), William Nylander, who supported his early botanical efforts. Vainio's earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the science, scientific study of naming, defining (Circumscription (taxonomy), circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxon, taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain (biology), domain, kingdom (biology), kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class (biology), class, order (biology), order, family (biology), family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transfo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Von Handel-Mazzetti
Heinrich Raphael Eduard Freiherr von Handel-Mazzetti (19 February 1882 in Vienna – 1 February 1940) was an Austrian botanist best known for his monograph of dandelions, many publications on the flora of China, and botanical explorations of that country. He was the cousin of novelist Enrica von Handel-Mazzetti (1871–1955). Life He studied botany at the University of Vienna, obtaining his doctorate in 1907. From 1905 he served as an assistant at the botanical institute in Vienna. In 1925 he was appointed curator to the Natural History Museum. In 1907 he published a world monograph of the genus ''Taraxacum'' (dandelions). Even if taxonomy of this genus has changed significantly. Handel-Mazzetti's book remains useful, especially because it is the only work of such scope until now. His earlier research involved scientific excursions to Switzerland (1906), Bosnia and Herzegovina (1909), followed by an expedition to Mesopotamia and Kurdistan (1910). On behalf of the Austrian Acade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hubert Winkler
Hubert Winkler (13 February 1875 in Prenzlau – 10 June 1941 in Breslau) was a German botanist, who specialized in tropical flora research. From 1895 he studied theology and botany at the University of Breslau, where in 1901/02 he worked as an assistant at the botanical garden. Afterwards, he worked at the Botanical Museum in Berlin and at the botanic garden in Victoria, Kamerun. In 1921 he became an associate professor of phytogeography at the University of Breslau, where in 1927 he attained a full professorship. In 1905, botanist Adolf Engler published '' Winklerella'', which is a genus of flowering plants from Cameroon, belonging to the family Podostemaceae. It was named in Hubert Winkler's honor. In 1908 he conducted botanical studies in the Malay Peninsula and the Dutch East Indies, where he also collected rattan plants and seed for importation to German colonies. In 1910 he carried out botanical investigations in East Africa. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cladoniaceae
The Cladoniaceae are a family of lichen-forming fungi in the order Lecanorales, comprising about 560 species distributed amongst 18 genera. This family is one of the largest among lichen-forming fungi and is globally distributed, from Arctic tundra to tropical rainforests, favouring humid environments while being intolerant of arid conditions. Molecular phylogenetics has significantly advanced the understanding of their complex taxonomic history, revealing intricate evolutionary relationships and leading to a refined classification. Notable members include reindeer moss and cup lichens of the genus '' Cladonia'', which consist of about 500 species and forms a significant part of the diet for large mammals in taiga and tundra ecosystems. A distinctive feature of many Cladoniaceae species is their dimorphic thallus: a scaly or crust-like form and a (shrub-like) secondary form known as a podetium or . These lichens typically grow on soil, decaying wood, or tree trunks, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phytogeography
Phytogeography (from Greek φυτόν, ''phytón'' = "plant" and γεωγραφία, ''geographía'' = "geography" meaning also distribution) or botanical geography is the branch of biogeography that is concerned with the geographic distribution of plant species and their influence on the earth's surface. Phytogeography is concerned with all aspects of plant distribution, from the controls on the distribution of individual species ranges (at both large and small scales, see species distribution) to the factors that govern the composition of entire communities and floras. Geobotany, by contrast, focuses on the geographic space's influence on plants. Fields Phytogeography is part of a more general science known as biogeography. Phytogeographers are concerned with patterns and process in plant distribution. Most of the major questions and kinds of approaches taken to answer such questions are held in common between phyto- and zoogeographers. Phytogeography in wider sense (or geobo ...

Heligoland
Heligoland (; , ; Heligolandic Frisian: , , Mooring Frisian: , ) is a small archipelago in the North Sea. The islands were historically possessions of Denmark, then became possessions of the United Kingdom from 1807 to 1890. Since 1890, they have been part of the German state of Schleswig-Holstein, although they were managed by the United Kingdom as a war prize from 1945 to 1952. The islands are located in the Heligoland Bight (part of the German Bight) in the southeastern corner of the North Sea and had a population of 1,127 at the end of 2016. They are the only German islands not in the vicinity of the mainland. They lie approximately by sea from Cuxhaven at the mouth of the River Elbe. In addition to German, the local population, who are ethnic Frisians, speak the Heligolandic dialect of the North Frisian language called . During a visit to the islands in 1841, August Heinrich Hoffmann von Fallersleben wrote the lyrics to the "", which became the national anthem o ...

Rügen
Rügen (; Rani: ''Rȯjana'', ''Rāna''; , ) is Germany's largest island. It is located off the Pomeranian coast in the Baltic Sea and belongs to the state of Mecklenburg-Western Pomerania. The "gateway" to Rügen island is the Hanseatic city of Stralsund, where it is linked to the mainland by road and railway via the Rügen Bridge and Causeway, two routes crossing the two-kilometre-wide Strelasund, a sound of the Baltic Sea. Rügen has a maximum length of (from north to south), a maximum width of in the south and an area of . The coast is characterised by numerous sandy beaches, lagoons () and open bays (), as well as peninsulas and headlands. In June 2011, UNESCO awarded the status of a World Heritage Site to the Jasmund National Park, characterised by vast stands of beeches and chalk cliffs like King's Chair, the main landmark of Rügen island. The island of Rügen is part of the district of Vorpommern-Rügen, with its county seat in Stralsund. The towns on Rüg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
