Theodor Marsson
Theodor Friedrich Marsson (8 November 1816 – 5 February 1892) was a German pharmacist and botanist. Marsson was born in Wolgast, Prussian Pomerania, just a year after the Swedish Empire had de-occupied the city, which had been under Swedish control since the Thirty Years' War. He was father-in-law to physiologist Leonard Landois (1837–1902). The son of a pharmacist, he studied chemistry under Justus von Liebig (1803–1873) at the University of Giessen. After completing his studies he took charge of the pharmacy in his hometown of Wolgast. In 1840 he provided necessary information towards the publication of Wilhelm Ludwig Ewald Schmidt's ''Flora von Pommern und Rügen'' (Flora of Pomerania and Rügen). In 1856 he was awarded an honorary PhD from the University of Greifswald. In 1869 he published a botanical study on Neuvorpommern and the islands of Usedom and Rügen titled ''Flora von Neuvorpommern und den Inseln Usedom und Rügen''. Around 1870 he sold the pharmacy in Wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Usedom
Usedom ( , ) is a Baltic Sea island in Pomerania, divided between Germany and Poland. It is the second largest Pomeranian island after Rügen, and the most populous island in the Baltic Sea. It lies north of the Szczecin Lagoon estuary of the Oder river. About 80% of the island belongs to the German district of Vorpommern-Greifswald in the state of Mecklenburg-Vorpommern. The eastern part and the largest city on the island, Świnoujście, are part of the Polish West Pomeranian Voivodeship. The island's total area is – in the German part and in the Polish part. Its population is 76,500 (German part 31,500; Polish part 45,000). With an annual average of 1,906 hours of sunshine, Usedom is the sunniest region of both Germany and Poland, and it is also one of the sunniest islands in the Baltic Sea, hence its nickname "Sun Island" (, ). The island has been a tourist destination since the Gründerzeit in the 19th century, and features resort architecture. Seaside resorts inc ...

Ascomycota
Ascomycota is a phylum of the kingdom Fungi that, together with the Basidiomycota, forms the subkingdom Dikarya. Its members are commonly known as the sac fungi or ascomycetes. It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the "ascus" (), a microscopic sexual reproduction, sexual structure in which nonmotile spores, called ascospores, are formed. However, some species of Ascomycota are Asexual reproduction, asexual and thus do not form asci or ascospores. Familiar examples of sac fungi include morels, truffles, yeast#Beer, brewers' and bakers' yeast, Xylaria, dead man's fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed "ascolichens") such as ''Cladonia'' belong to the Ascomycota. Ascomycota is a monophyletic group (containing all of the descendants of a common ancestor). Previously placed in the Basidiomycota along with asexual species from other fungal taxa, asexual (or Teleomorph, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and mold (fungus), molds, as well as the more familiar mushrooms. These organisms are classified as one of the kingdom (biology)#Six kingdoms (1998), traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of motility, mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mycology
Mycology is the branch of biology concerned with the study of fungus, fungi, including their Taxonomy (biology), taxonomy, genetics, biochemistry, biochemical properties, and ethnomycology, use by humans. Fungi can be a source of tinder, Edible mushroom, food, traditional medicine, as well as entheogens, poison, and fungal infection, infection. Yeasts are among the most heavily utilized members of the fungus kingdom, particularly in food manufacturing. Mycology branches into the field of phytopathology, the study of plant diseases. The two disciplines are closely related, because the vast majority of plant pathogens are fungi. A biologist specializing in mycology is called a mycologist. Overview The word ''mycology'' comes from the Greek language, Ancient Greek: wikt:μύκης, μύκης (''mukēs''), meaning "fungus" and the suffix (''-logia''), meaning "study." Pioneer mycologists included Elias Magnus Fries, Christiaan Hendrik Persoon, Heinrich Anton de Bary, Elizabeth E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diatoms
A diatom (Neo-Latin ''diatoma'') is any member of a large group comprising several Genus, genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of Earth's Biomass (ecology), biomass. They generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion tonnes of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The Protist shell, shells of dead diatoms are a significant component of marine sediment, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of fresh-water lakes. Diatoms are unicellular organisms: they occur either as solitary cells or in Colony (biology), colonies, which can take the shape of ribb ...

Bryozoa
Bryozoa (also known as the Polyzoa, Ectoprocta or commonly as moss animals) are a phylum of simple, aquatic animal, aquatic invertebrate animals, nearly all living in sedentary Colony (biology), colonies. Typically about long, they have a special feeding structure called a lophophore, a "crown" of tentacles used for filter feeder, filter feeding. Most Marine (ocean), marine bryozoans live in tropical waters, but a few are found in oceanic trenches and polar waters. The bryozoans are classified as the Stenolaemata, marine bryozoans (Stenolaemata), Phylactolaemata, freshwater bryozoans (Phylactolaemata), and Gymnolaemata, mostly-marine bryozoans (Gymnolaemata), a few members of which prefer brackish water. 5,869living species are known. Originally all of the crown group Bryozoa were colonial, but as an adaptation to a mesopsammal (interstitial spaces in marine sand) life or to deep-sea habitats, secondarily solitary forms have since evolved. Solitary species have been described i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirripede
Barnacles are arthropods of the subclass Cirripedia in the subphylum Crustacea. They are related to crabs and lobsters, with similar nauplius larvae. Barnacles are exclusively marine invertebrates; many species live in shallow and tidal waters. Some 2,100 species have been described. Barnacle adults are sessile; most are suspension feeders with hard calcareous shells, but the Rhizocephala are specialized parasites of other crustaceans, with reduced bodies. Barnacles have existed since at least the mid-Carboniferous, some 325 million years ago. In folklore, barnacle geese were once held to emerge fully formed from goose barnacles. Both goose barnacles and the Chilean giant barnacle are fished and eaten. Barnacles are economically significant as biofouling on ships, where they cause hydrodynamic drag, reducing efficiency. Etymology The word "barnacle" is attested in the early 13th century as Middle English "bernekke" or "bernake", close to Old French "bernaque" and med ...

Ostracod
Ostracods, or ostracodes, are a Class (biology), class of the crustacean, Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 33,000 species (only 13,000 of which are extant taxon, extant) have been identified,Brandão, S.N.; Antonietto, L.S; Nery, D.G.; Santos, S.G.; Karanovic, I. (2023). World Ostracoda Database. Accessed at https://www.marinespecies.org/ostracoda on 2023-09-12. grouped into 7 valid orders. They are small crustaceans, typically around in size, but varying from , the latter in the case of the marine ''Gigantocypris.'' The largest known freshwater species is ''Megalocypris princeps'', which reach 8 mm in length. In most cases, their bodies are flattened from side to side and protected by a bivalve-like valve or "shell" made of chitin, and often calcium carbonate. The family Entocytheridae and many planktonic forms do not have calcium carbonate. The hinge of the two valves is in the upper (dorsal) region of the body. Ostracods are grouped toget ...

Foraminifera
Foraminifera ( ; Latin for "hole bearers"; informally called "forams") are unicellular organism, single-celled organisms, members of a phylum or class (biology), class of Rhizarian protists characterized by streaming granular Ectoplasm (cell biology), ectoplasm for catching food and other uses; and commonly an external shell (called a "Test (biology), test") of diverse forms and materials. Tests of chitin (found in some simple genera, and ''Textularia'' in particular) are believed to be the most primitive type. Most foraminifera are marine, the majority of which live on or within the seafloor sediment (i.e., are benthos, benthic, with different sized species playing a role within the macrobenthos, meiobenthos, and Benthos, microbenthos), while a smaller number float in the water column at various depths (i.e., are planktonic), which belong to the suborder Globigerinina. Fewer are known from freshwater or brackish conditions, and some very few (nonaquatic) soil species have been id ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
