Josef Hafellner
Josef Hafellner (1951– ) is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus '' Karschia''. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work ''Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae'' has been described as "probably the single most influential publication in lichen systematics in t ...

Karl-Franzens-Universität
The University of Graz (german: link=no, Karl-Franzens-Universität Graz, ), located in Graz, Austria, is the largest and oldest university in Styria, as well as the second-largest and second-oldest university in Austria. History The university was founded in 1585 by Archduke Charles II of Austria. The bull of 1 January 1586, published on 15 April 1586, was approved by Pope Sixtus V. For most of its existence it was controlled by the Catholic Church, and was closed in 1782 by Emperor Joseph II in an attempt to gain state control over educational institutions. Joseph II transformed it into a ''lyceum'', where civil servants and medical personnel were trained. In 1827 it was re-instituted as a university by Emperor Francis I, thus gaining the name ''Karl-Franzens-Universität'', meaning ''Charles Francis University''. Over 30,000 students are currently enrolled at the university. Academics The university is divided into six faculties, the two largest are the Faculty of ...

Classification (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, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biologica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthonia Pepei
''Arthonia'' is a genus of lichens in the family Arthoniaceae. It was circumscribed by Swedish botanist Erik Acharius in 1806.

Hafellnera
''Schaereria'' is a genus of lichen-forming fungi. It is the sole genus in the family Schaereriaceae, which itself is the only family in the Schaereriales, an order in the subclass Ostropomycetidae of the class Lecanoromycetes. Taxonomy The genus name of ''Schaereria'' is in honour of Ludwig Emanuel Schaerer (1785–1853), who was a Swiss pastor and lichenologist. Genus ''Schaereria'' was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855, with '' Schaereria lugubris'' assigned as the type species. The genus was accepted a few years later by Theodor Magnus Fries. It subsequently fell into disuse as William Nylander placed it in synonymy with ''Lecidea''. Josef Poelt and Antonín Vězda resurrected the genus in 1977, and included '' S. cinereorufa''. ''Schaereria'' is one of several dozen genera whose species were previously included in the large genus ''Lecidea''. However, ''Lecidea'' has a different ascus structure than ''Schaereria''. The family S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxon
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Publication
: ''For a broader class of literature, see Academic publishing.'' Scientific literature comprises scholarly publications that report original empirical and theoretical work in the natural and social sciences. Within an academic field, scientific literature is often referred to as the literature. Academic publishing is the process of contributing the results of one's research into the literature, which often requires a peer-review process. Original scientific research published for the first time in scientific journals is called the primary literature. Patents and technical reports, for minor research results and engineering and design work (including computer software), can also be considered primary literature. Secondary sources include review articles (which summarize the findings of published studies to highlight advances and new lines of research) and books (for large projects or broad arguments, including compilations of articles). Tertiary sources might include encycl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific Collection
A scientific collection is a collection of items that are preserved, catalogued, and managed for the purpose of scientific study. Scientific collections dealing specifically with organisms plants, fungi, animals, insects and their remains, may also be called natural history collections or biological collections. The latter may contain either living stocks or preserved repositories of biodiversity specimens and materials. Scientific collections hold a tangible portion of the cumulative evidence base in such fields as biology (especially taxonomy and evolutionary biology), geology, and archaeology. They may be stored and managed by governments, educational institutions (e.g. colleges and universities), private organizations (including museums), or individuals. Prominent uses of scientific collections include the systematic description and identification of biological species, the study and prediction of long-term historical trends (including impacts of climate change), the dating ...

European Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French–Italian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
