Giovanni Battista De Toni
Giovanni Battista de Toni (2 January 1864, Venice – 31 July 1924, Modena) was an Italian botanist, mycologist and phycologist. In 1885 he graduated from the University of Padua, where he studied natural sciences and chemistry with Pier Andrea Saccardo (1845-1920) and Francesco Filippuzzi (1824-1886). For several years, he worked as a librarian in the museum of Padua, afterwards teaching botany at the University of Camerino (1900). Following duties as a professor of botany in Sassari, he relocated to Modena, where from 1903, he served as a professor of botany and as associate director of the botanical garden. During his career, he took numerous scientific trips throughout Europe — travels where he met and studied with scientists that included Jacob Georg Agardh (1813-1901), Alfred Mathieu Giard (1846-1908), Louis Mangin (1852-1937) and Narcisse Théophile Patouillard (1854-1926). His earlier work dealt mainly with plant systematics, his later research involved studies i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Venice
Venice ( ; it, Venezia ; vec, Venesia or ) is a city in northeastern Italy and the capital of the Veneto Regions of Italy, region. It is built on a group of 118 small islands that are separated by canals and linked by over 400 bridges. The islands are in the shallow Venetian Lagoon, an enclosed bay lying between the mouths of the Po River, Po and the Piave River, Piave rivers (more exactly between the Brenta (river), Brenta and the Sile (river), Sile). In 2020, around 258,685 people resided in greater Venice or the ''Comune di Venezia'', of whom around 55,000 live in the historical island city of Venice (''centro storico'') and the rest on the mainland (''terraferma''). Together with the cities of Padua, Italy, Padua and Treviso, Italy, Treviso, Venice is included in the Padua-Treviso-Venice Metropolitan Area (PATREVE), which is considered a statistical metropolitan area, with a total population of 2.6 million. The name is derived from the ancient Adri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Narcisse Théophile Patouillard
Narcisse Théophile Patouillard (2 July 1854 – 30 March 1926) was a French pharmacist and mycologist. He was born in Macornay, a town in the department of Jura (department), Jura. He studied in Besançon, then furthered his education at the École Supérieure de Pharmacie in Paris, where in 1884 he earned a diploma with a doctoral thesis involving the structure and classification of Hymenomycetes called "''Des Hyménomycètes au point de vue de leur structure et de leur classification''". Des Hyménomycètes au point de vue de leur structure et leur classification Patouillard was a practicing pharmacist for more than forty years, first in Poligny, Jura, Poligny (1881–84), and later in Fontenay-sous-Bois (1884–85), Paris (1886–1898) and Neuilly-sur-Seine (beginning in 1 ...

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johannesbaptistia
''Johannesbaptistia'' is a genus of brackish–freshwater cyanobacteria which has a very characteristic morphology. It is the only member of the family Cyanothrichaceae. When the name was changed from ''Cyanothrix'' to ''Johannesbaptistia'' (due to the rules of priority in the International Code of Nomenclature for algae, fungi, and plants), the family name was not changed. The genus name of ''Johannesbaptistia'' is in honour of Giovanni Battista de Toni Giovanni Battista de Toni (2 January 1864, Venice – 31 July 1924, Modena) was an Italian botanist, mycologist and phycologist.

Thalassiosiraceae
Thalassiosiraceae is a family of diatoms in the order Thalassiosirales. The family of Thalassiosiraceae have the unique quality of having a flat valve face. These diatoms are common in brackish, nearshore, and open-ocean habitats, with approximately the same number of freshwater and marine species. Thalassiosiraceae are a centric diatom full of fultoportula. These can often be mistaken for Areola. These belong to many diatom families and can be found in different forms such as the different Areolae that can be found on ''Navicula or Gomphoneis known as lineolate and punctate.'' Unlike naviculaceae who are symmetrical in shape some Thalassiosiraceae take on being tangentially undulate. The species ''Thalassiosira pseudonana'' was chosen as the first eukaryotic marine phytoplankton for whole genome sequencing. ''T. pseudonana'' was selected for this study because it is a model for diatom physiology studies, belongs to a genus widely distributed throughout the world's oceans, a ...

Diatom
A diatom (Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, 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 ...

Leonardo Da Vinci
Leonardo di ser Piero da Vinci (15 April 14522 May 1519) was an Italian polymath of the High Renaissance who was active as a painter, Drawing, draughtsman, engineer, scientist, theorist, sculptor, and architect. While his fame initially rested on his achievements as a painter, he also became known for #Journals and notes, his notebooks, in which he made drawings and notes on a variety of subjects, including anatomy, astronomy, botany, cartography, painting, and paleontology. Leonardo is widely regarded to have been a genius who epitomized the Renaissance humanism, Renaissance humanist ideal, and his List of works by Leonardo da Vinci, collective works comprise a contribution to later generations of artists matched only by that of his younger contemporary, Michelangelo. Born Legitimacy (family law), out of wedlock to a successful Civil law notary, notary and a lower-class woman in, or near, Vinci, Tuscany, Vinci, he was educated in Florence by the Italian painter and sculptor ...

Fungi
A fungus ( : fungi or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as a kingdom, separately from the other eukaryotic kingdoms, which by one traditional classification include Plantae, Animalia, 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 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 organisms, named the ''Eumycota'' (''t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...
