Bryoria Kockiana
''Bryoria kockiana'' (Kock's horsehair lichen) is a species of horsehair lichen in the family Parmeliaceae. It is found in North America, where it grows from the branches of conifer trees. Taxonomy The lichen was described as a new species in 2013 by Saara Velmala, Leena Myllys, and Trevor Goward. The type specimen was collected in Fairbanks, Alaska in July 2011. The specific epithet ''kockiana'' honours Henry Kock, a horticulturalist from Ontario whose widow won an environmental fund-raising auction to purchase the right to name the species. It had previously been assigned to ''Bryoria implexa'', but genetic analysis showed that this species is restricted in distribution to Europe and Asia, and its North America counterpart represented a different species. A later DNA study corroborated the validity of the species. Description The thallus of ''Bryoria kockiana'', which hangs from branches, can grow up to . It is greyish brown or pale brown to brown in colour, which branches 0.1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horsehair Lichen
''Bryoria'' is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens. The genus has a widespread distribution, especially in boreal and cool temperate areas. Taxonomy ''Bryoria'' was circumscribed in 1977 by lichenologists Irwin Brodo and David Hawksworth, with ''Bryoria trichodes'' as the type species. Description ''Bryoria'' species are fruticose, slender and hair-like, tending to grow hanging (pendent) or like a small bush. They range in colour from dark brown to pale greyish brown to grey in some species. Ascospores are colourless, ellipsoid, numbering eight per ascus. Other hair-like lichens that may be confused with ''Bryoria'' include dark brown species of '' Bryocaulon'', '' Nodobryoria'', ''Pseudephebe'', '' Alectoria'', or ''Cetraria''. Habitat and distribution Found almost exclusively on conifers, or on tundra soil, ''Bryoria'' collectively has a widespread distribution, especially in boreal and cool tempe ...

Pseudocyphella
Pseudocyphellae (singular ''pseudocyphella'') are structures in lichens that appear as tiny pores on the outer surface (the cortex of the lichen. They are caused when there is a break in the cortex of the lichen, and the medullary hyphae extend to the surface. Pseudocyphellae are the same colour as the medulla of the lichen, which is generally white, but can be yellow in some species of ''Pseudocyphellaria'' and in ''Bryoria fremontii''. The presence/absence, abundance, colour, and shape of pseudocyphellae can all be diagnostic features used to identify different species. They facilitate gas exchange through the surface of the lichen, and may provide an adaptive advantage in temperate In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout t ... environments. References *Brodo, I. M., S. D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Secondary Metabolite
Secondary metabolites, also called specialised metabolites, toxins, secondary products, or natural products, are organic compounds produced by any lifeform, e.g. bacteria, fungi, animals, or plants, which are not directly involved in the normal growth, development, or reproduction of the organism. Instead, they generally mediate ecological interactions, which may produce a selective advantage for the organism by increasing its survivability or fecundity. Specific secondary metabolites are often restricted to a narrow set of species within a phylogenetic group. Secondary metabolites often play an important role in plant defense against herbivory and other interspecies defenses. Humans use secondary metabolites as medicines, flavourings, pigments, and recreational drugs. The term secondary metabolite was first coined by Albrecht Kossel, a 1910 Nobel Prize laureate for medicine and physiology in 1910. 30 years later a Polish botanist Friedrich Czapek described secondary metabolit ...
