Ingvar Kärnefelt
Jan Eric Ingvar Kärnefelt (born 1944) is a Swedish lichenologist. Early life and education Kärnefelt was born in Gothenburg, Sweden in 1944. His initial goal in his higher-level studies at University of Cologne in 1966–1967 was to become a dentist. He changed courses in 1968, turning instead to biology at the University of Gothenburg in 1968. Gunnar Degelius, his first teacher during undergraduate studies in botany in 1968, inspired him and others. After Degelius' retirement in 1969, Ingvar continued his studies at Lund University, where Hans Runemark held a position in systematic botany. In 1971 he met Ove Almborn, who became his supervisor. In 1979, he defended his thesis titled "The brown fruticose species of ''Cetraria''". The thesis was later awarded a prize for the best doctoral dissertation in botany at Lund University during a 5-year period by the Royal Physiographic Society in Lund. Career Kärnefelt became associate professor at the Department of Systematic Bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Caloplaca Kaernefeltii
''Caloplaca'' is a lichen genus comprising a number of distinct species. Members of the genus are commonly called firedot lichen, jewel lichen.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, gold lichens, "orange lichens", but they are not always orange, as in the case of '' C. albovariegata''. The distribution of this lichen genus is worldwide, extending from Antarctica to the high Arctic. It includes a portion of northern North America and the Russian High Arctic. There are about thirty species of ''Caloplaca'' in the flora of the British Isles. An example species in this genus is '' Caloplaca saxicola'', a lichen with worldwide distribution including the Antarctic continent, Europe and northern North America including the northern reaches of the Canadian boreal forests. A new species of ''Caloplaca'', '' C. obamae'', the first species to be named in honor of Barack Obama, was discovered in 2007 on Santa Rosa Island in California and ...

Kaernefia
''Kaernefia'' is a genus of crustose lichens in the family Teloschistaceae. It has three species, found in Australia or South Africa. Taxonomy ''Kaernefia'' was circumscribed in 2013 by Sergey Kondratyuk, John Elix, Arne Thell, and Jae-Seoun Hur, based on a molecular phylogenetic analysis of the family Teloschistaceae. They assigned '' Kaernefia kaernefeltii'' as the type species of the new genus. The generic name honours their colleague, Swedish lichenologist Ingvar Kärnefelt, for "his many contributions to lichenology, in particular lichens of the Teloschistaceae and Parmeliaceae". Description Species in ''Kaernefia'' have a poorly developed, indistinct thallus comprising tiny granules or granule-like isidia. It ranges in colour from yellow, to orange to greenish orange or brownish orange. It produces lecanorine apothecia with a thick margin. Lichen products reported from the genus include parietin and ''O''-methylvioxanthin as major compounds, and trace amounts of fallac ...

Kaernefeltia
''Kaernefeltia'' is a genus of lichenized fungi in the family Parmeliaceae. Taxonomy ''Kaernefeltia'' was circumscribed by lichenologists Arne Thell and Trevor Goward in 1996 to contain the western North American species formerly known as ''Cetraria californica'' (the type species) and ''C. merrillii''. The genus name honours Swedish lichenologist Ingvar Kärnefelt. In 2017, Divakar and colleagues used a recently developed "temporal phylogenetic" approach to identify temporal bands for specific taxonomic ranks in the family Parmeliaceae, suggesting that groups of species that diverged within the time window of 29.45–32.55 million years ago represent genera. They proposed to synonymize ''Kaernefeltia'' with ''Nephromopsis ''Nephromopsis'' is a genus of lichenized fungi within the Parmeliaceae The Parmeliaceae is a large and diverse family of Lecanoromycetes.

Ingvariella
''Ingvariella'' is a lichen genus in the family Stictidaceae. Circumscribed in 1997, the genus is monotypic, containing the single widespread lichen species ''Ingvariella bispora''. The species was originally named ''Urceolaria bispora'' by Italian lichenologist Francesco Baglietto in 1871. ''Ingvariella'' is named in honour of Swedish lichenologist Ingvar Kärnefelt Jan Eric Ingvar Kärnefelt (born 1944) is a Swedish lichenologist.

Ikaeria
''Ikaeria'' is a genus of two species of crustose lichens in the family Teloschistaceae. Both species grow on twig bark of shrubs and trees. It was circumscribed in 2017 by lichenologists Sergey Kondratyuk, Dalip Kumar Upreti, and Jae-Seoun Hur, with '' Ikaeria aurantiellina'' assigned as the type species. This lichen was previously placed in the genus ''Caloplaca'', but molecular phylogenetic analysis showed that it belonged in a lineage that was genetically distinct from that genus. '' Ikaeria serusiauxii'' was added to the genus in 2020. ''Ikaeria'' has a sister group relationship with genus ''Yoshimuria''; both are in the subfamily Caloplacoideae of the Teloschistaceae. ''Ikaeria'' is named in honour of Swedish lichenologist Ingvar Kärnefelt Jan Eric Ingvar Kärnefelt (born 1944) is a Swedish lichenologist.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
