Niebla Effusa
''Niebla effusa '' is a fruticose lichen that grows on gravelly soil along the foggy Pacific Coast of Baja California from near Punta Colonet south to near Punta Rosarito.Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot. Misc. 14 The epithet, ''effusa'' is in reference to the thallus spreading widely along the surface. Distinguishing features ''Niebla effusa'' is recognized by the thallus divided into a tangled mat of irregularly cylindrical-prismatic branches without a central connection at base–to as much as 1 meter in diameter, weighing more than 1 kg—and by the ultimate parts of the primary branches becoming hooked, dilated, and fringed from which there are many erect branchlets. Black dot-like pycnidia are usually infrequent and scattered along the branch margins and cortical ridges. A key lichen substance is salazinic acid, which may be accompanied by an unknown, possibly scabrosin derivative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fruticose Lichen
A fruticose lichen is a form of lichen fungi that is characterized by a coral-like shrubby or bushy growth structure. It is formed from a symbiotic relationship of a photobiont such as green algae or less commonly cyanobacteria and one, two or more mycobionts. Fruticose lichens are not a monophyletic and holophyletic lineage, but is a form encountered in many classes. Fruticose lichens have a complex vegetation structure, and are characterized by an ascending, bushy or pendulous appearance. As with other lichens, many fruticose lichens can endure high degrees of desiccation. They grow slowly and often occur in habitats such as on tree barks, on rock surfaces and on soils in the Arctic and mountain regions. Characteristics Fruticose lichens are lichens composed of a shrubby or bushy thallus and a holdfast. The thallus is the vegetative body of a lichen that does not have true leaves, stems, or roots. The thallus colour is affected by the algae in the lichen, compounds created by t ... [...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.

California Floristic Province
The California Floristic Province (CFP) is a floristic province with a Mediterranean-type climate located on the Pacific Coast of North America with a distinctive flora similar to other regions with a winter rainfall and summer drought climate like the Mediterranean Basin. This biodiversity hotspot is known for being the home of the Sierran giant sequoia tree and its close relative the coast redwood. In 1996, the Province was designated as a biodiversity hotspot allowing it to join ranks among 33 other areas in the world with many endemic species. To be named a biodiversity hotspot, an area has to contain species and plant life that cannot be found anywhere else in the world. The California Floristic Province is home to over 3,000 species of vascular plants, 60% of which are endemic to the province. The California Floristic Province belongs to the Madrean Region of the Holarctic (or Boreal) Floristic Kingdom. As part of the Madrean Region, it is bordered on its east by the Grea ...

Niebla Palmeri
''Niebla palmeri'' is a fruticose lichen that infrequently occurs on sandy beaches or gravelly soil along the Pacific Coast from San Diego, California to mesas just north of Punta Baja, about 15 miles southeast of El Rosario, Baja California.Spjut, R. W. 1996. ''Niebla'' and ''Vermilacinia'' (Ramalinaceae) from California and Baja California. Sida Bot.

Sekikaic Acid
Sekikaic acid is an organic compound in the structural class of chemicals known as depsides. It is found in some lichens. First isolated from '' Ramalina sekika'', it is a fairly common lichen product in ''Ramalina'' and ''Cladonia'', both genera of lichen-forming fungi. The species epithet of the powdery lichen '' Lepraria sekikaica'' refers to the presence of this substance—a rarity in genus ''Lepraria''. Properties In its purified form, sekikaic acid exists as colourless rectangular prisms or rhombic plates. Its molecular formula is C22H2608. It has a melting point of . An ethanolic solution of sekikaic acid reacts with iron(III) chloride to produce a violet colour. Its ultraviolet spectrum has three peaks of maximum absorption (λmax) at 219, 263, and 303 nm. Sekikaic acid has been demonstrated to have several biological activities in laboratory experiments. These include antioxidant activity, inhibition of the enzymes α-glucosidase and α-amylase, hypoglycemic ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Punta Colonet
Punta Colonet (Chuwílo Ksaay (''dry arroyo'') in the Kiliwa language) is a town located in Ensenada Municipality, Baja California, Mexico.
