Melanohalea Clairi
''Melanohalea clairi'' is a species of lichen in the family Parmeliaceae. It was described as a new species in 2016. It is known from only two locations in the United States. The type specimen was collected from the White River National Forest in Colorado, in juniper-oak mountainous shrubland. Here it was found growing on Gambel oak. It has also been collected from the Wasatch Front in central Utah, where it was recorded on bigtooth maple. The lichen is morphologically similar to ''Melanohalea subolivacea ''Melanohalea subolivacea'', commonly known as the brown-eyed camouflage lichen, is a species of foliose lichen in the family Parmeliaceae. Taxonomy The lichen was first documented by Finnish lichenologist William Nylander. The type specimen wa ...'', but is genetically distinct from that species.

Acer Grandidentatum
''Acer grandidentatum'', commonly called bigtooth maple, is a species of maple native to interior western North America. It occurs in scattered populations from western Montana to central Texas in the United States and south to Coahuila in northern Mexico. Description It is a small to medium-sized deciduous tree growing to tall and a trunk of diameter. The bark is dark brown to gray, with narrow fissures and flat ridges creating plate-like scales; it is thin and easily damaged. The leaves are opposite, simple, long and broad, with three to five deep, bluntly-pointed lobes, three of the lobes large and two small ones (not always present) at the leaf base; the three major lobes each have 3–5 small subsidiary lobules. The leaves turn golden yellow to red in autumn (less reliably in warmer areas). The flowers appear with the leaves in mid spring; they are produced in corymbs of 5–15 together, each flower yellow-green, about diameter, with no petals. The fruit is a pa ...

Taxa Named By Ana Crespo
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 system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichens Of North America
Irwin M. Brodo (born 1935) is an emeritus scientist at the Canadian Museum of Nature, in Ottawa, Ontario, Canada. He is an authority on the identification and biology of lichens. Irwin Brodo was honored in 1994 with an Acharius Medal presented to him by the International Association for Lichenology. Brodo did his undergraduate studies at Columbia University, and received a master's degree from Cornell University. He earned a Ph.D. in lichenology under the supervision of Henry Imshaug at Michigan State University. He later went on to teach at Université Laval and the University of Alaska, and he also supervised master's students at the University of Ottawa and Carleton University. Brodo's list of publications includes 75 research papers, 8 popular articles, 22 reviews and 6 editorials and obituaries. In 1993, Brodie was awarded the Mary E. Elliot Service Award for his meritorious service to the Canadian Botanical Association. One of Irwin Brodo's great achievements was the pu ...

Melanohalea
''Melanohalea'' is a genus of foliose lichens in the family Parmeliaceae. It contains 30 mostly Northern Hemisphere species that grow on bark or on wood. The genus is characterized by the presence of pseudocyphellae, usually on warts or on the tips of isidia, a non-pored and a medulla containing depsidones or lacking secondary compounds. ''Melanohalea'' was circumscribed in 2004 as a segregate of the morphologically similar genus ''Melanelia''. Taxonomy ''Melanohalea'' was circumscribed in 2004 by lichenologists Oscar Blanco, Ana Crespo, Pradeep K. Divakar, Theodore Esslinger, David L. Hawksworth and H. Thorsten Lumbsch. It is a segregate of ''Melanelia'', a genus created in 1978 to contain the brown '' Parmelia'' species. The circumscription of this genus was questioned later, especially after early molecular phylogenetics studies demonstrated that it was not monophyletic. Subsequently, two genera, '' Melanelixia'' and ''Melanohalea'', were created. ''Melanohalea'' or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melanohalea Subolivacea
''Melanohalea subolivacea'', commonly known as the brown-eyed camouflage lichen, is a species of foliose lichen in the family Parmeliaceae. Taxonomy The lichen was first documented by Finnish lichenologist William Nylander. The type specimen was found growing on rocks in the San Gabriel Mountains of Southern California, at an elevation of . The lichen was formally described in a publication by American lichenologist Hermann Edward Hasse in 1897, with authorship attributed to Nylander. Named for its resemblance to '' Parmelia olivacea'', it was distinguished from that species by its spore size, measuring 8–9 by 5 μm. It was transferred to the genus ''Melanelia'' by Ted Esslinger in 1978, and then to the newly circumscribed genus '' Melanohalea'' in 2004. ''Melanohalea subolivacea'' has been given the common name "brown-eyed camouflage lichen". Molecular phylogenetic studies of '' Melanohalea'' species show that ''Melanohalea subolivacea'' is closely related, but genetic ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance ( shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fr ...

Utah
Utah ( , ) is a state in the Mountain West subregion of the Western United States. Utah is a landlocked U.S. state bordered to its east by Colorado, to its northeast by Wyoming, to its north by Idaho, to its south by Arizona, and to its west by Nevada. Utah also touches a corner of New Mexico in the southeast. Of the fifty U.S. states, Utah is the 13th-largest by area; with a population over three million, it is the 30th-most-populous and 11th-least-densely populated. Urban development is mostly concentrated in two areas: the Wasatch Front in the north-central part of the state, which is home to roughly two-thirds of the population and includes the capital city, Salt Lake City; and Washington County in the southwest, with more than 180,000 residents. Most of the western half of Utah lies in the Great Basin. Utah has been inhabited for thousands of years by various indigenous groups such as the ancient Puebloans, Navajo and Ute. The Spanish were the first Europ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
