Franz Xaver Von Wulfen
Franz Xaver Freiherr von Wulfen (5 November 1728 – 17 March 1805) was an Austrian botanist, zoologist, mineralogist, alpinist, and Jesuit priest. He is credited with discovering the flowering plants '' Wulfenia carinthiaca'', ''Saxifraga moschata'', and '' Stellaria bulbosa''. In 1845 the lead molybdate mineral wulfenite was named in his honor by Wilhelm Karl von Haidinger. Life Wulfen was born in Belgrade. His father, Christian Friedrich von Wulfen, was a high-ranking lieutenant in the Austrian Army of Swedish descent. His mother, née Mariassy, was a Hungarian countess. Franz's education took place at Kaschau Gymnasium in present-day Košice, Slovakia. When he was 17, he joined a Jesuit school in Vienna. Following his graduation, he became a school instructor (chiefly of mathematics and physics) in Vienna, Graz, Neusohl, Gorz, Laibach (Ljubljana), and from 1764 Klagenfurt. After the Suppression of the Society of Jesus in the 1760s, he remained in Klagenfurt until hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Abramo Bartolommeo Massalongo
Abramo Bartolommeo Massalongo (13 May 1824 – 25 May 1860) was an Italian paleobotanist and lichenologist. He was born in Tregnago in the Province of Verona and took a great interest in botany as a young man. Massalongo joined the faculty of medicine at the University of Padua in 1844.Cappelletii, Maurizia Alippi (2008)"Abramo Bartolomeo Massalongo"(in Italian). ''Dizionario Biografico degli Italiani, Volume 71''. Retrieved 7 October 2012. Along with Gustav Wilhelm Körber, he founded the "Italian-Silesian" school of lichenology. He also collaborated with Martino Anzi. He was the husband of Maria Colognato and the father of hepaticologist Caro Benigno Massalongo. He also worked in the scientific field of herpetology. In 1859 his ''Catalogo dei rettili delle province venete'' was published in Venice. Massalongo died in Verona in 1860. He was honoured in 1855, when German lichenologist Gustav Wilhelm Körber circumscribed ''Massalongia'' which is a genus of lichen-forming fung ...

Stictic Acid
Stictic acid is an aromatic organic compound, a product of secondary metabolism in some species of lichens. Stictic acid is the subject of preliminary biomedical research. Stictic acid has cytotoxic and apoptotic effects ''in vitro''. Computational studies suggest stictic acid may also stimulate p53 p53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers.

Rhizocarpon
''Rhizocarpon'' is a genus of crustose lichen, crustose, saxicolous lichen, saxicolous (or sometimes lichenicolous fungus, lichenicolous), lichens in the family Rhizocarpaceae. The genus is common in arctic-alpine environments, but also occurs throughout temperate, subtropical, and even tropical regions. They are commonly known as map lichens because of the prothallus#In lichens, prothallus forming border-like bands between colonies in some species, like the common map lichen (''Rhizocarpon geographicum''). Taxonomy and phylogeny Together with three small genera (''Catolechia'', ''Poeltinula'' and ''Epilichen''), ''Rhizocarpon'' constitutes the family Rhizocarpaceae. Historically, ca 389 names have been used. However, many species concepts are ill-defined, many names have been synonymized and new species are regularly being described, so true number of species is not entirely clear as of now, but is estimated to be around 200. In molecular work, the genus has also been shown to b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
