Monterey County, California
Monterey County ( ), officially the County of Monterey, is a county (United States), county located on the Pacific Ocean, Pacific coast in the U.S. state of California. As of the 2020 United States census, its population was 439,035. The county's largest city and county seat is Salinas, California, Salinas. Monterey County comprises the Salinas, California, Metropolitan Statistical Area. It borders on the southern part of Monterey Bay, after which it is named (northern half of the bay is in Santa Cruz County, California, Santa Cruz County). Monterey County is a member of the regional governmental agency: the Association of Monterey Bay Area Governments. Scenic features along the coastline - including Carmel-by-the-Sea, California, Carmel-by-the-Sea, Big Sur, California State Route 1, State Route 1, and the 17 Mile Drive on the Monterey Peninsula - have made the county famous around the world.

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Witch's Broom
Witch's broom or witches' broom is a deformity in a woody plant, typically a tree, where the natural structure of the plant is changed. A dense mass of shoots grows from a single point, with the resulting structure resembling a broom or a bird's nest. It is sometimes caused by pathogens. Diseases with symptoms of witches' broom, caused by phytoplasmas or basidiomycetes, are economically important in a number of crop plants, including the cocoa tree ''Theobroma cacao'', jujube (''Ziziphus jujuba'') and the timber tree '' Melia azedarach''. Causes A tree's characteristic shape, or habit, is in part the product of auxins, hormones which control the growth of secondary apices. The growth of an offshoot is limited by the auxin, while that of the parent branch is not. In cases of witch's broom, the normal hierarchy of buds is interrupted, and apices grow indiscriminately. This can be caused by cytokinin, a phytohormone which interferes with growth regulation. The phenomenon c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manzanita
Manzanita is a common name for many species of the genus '' Arctostaphylos''. They are evergreen shrubs or small trees present in the chaparral biome of western North America, where they occur from Southern British Columbia and Washington to Oregon, California, Utah, Arizona, New Mexico, and Texas in the United States, and throughout Mexico. Manzanitas can live in places with poor soil and little water. They are characterized by smooth orange or red bark and stiff, twisting branches. There are 107 species and subspecies of manzanita, 95 of which are found in the Mediterranean climate and colder mountainous regions of California, ranging from ground-hugging coastal and mountain species to small trees up to 20 feet (6m) tall. Manzanitas bloom from winter to early spring and carry berries in spring and summer. The berries and flowers of most species are edible. The word ''manzanita'' is the Spanish diminutive of ''manzana'' meaning "little apple". The name manzanita is also somet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Exobasidium Vaccinii
''Exobasidium vaccinii'', commonly known as “red leaf disease,” or “Azalea Gall,” is a biotrophic species of fungus that causes galls on ericaceous plant species, such as blueberry and azalea (''Vaccinium'' and ''Rhododendron'' spp.). ''Exobasidium vaccinii'' is considered the type species of the Exobasidium genus.Piątek, M., Lutz, M. & Welton, P. Exobasidium darwinii, a new Hawaiian species infecting endemic Vaccinium reticulatum in Haleakala National Park. Mycol Progress 11, 361–371 (2012). https://doi.org/10.1007/s11557-011-0751-4 As a member of the Ustilagomycota, it is a basidiomycete closely related to smut fungi. Karl Wilhelm Gottlieb Leopold Fuckel first described the species in 1861 under the basionym ''Fusidium vaccinii,'' but in 1867 Mikhail Stepanovich Voronin (often cited as “Woronin”) later placed it in the genus '' Exobasidium''. The type specimen is from Germany, and it is held in the Swedish Museum of Natural History. ''Exobasidium vaccinii'', in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungi Of North America
A fungus (: fungi , , , or ; or funguses) is any member of the group of eukaryotic organisms that includes microorganisms such as yeasts and molds, as well as the more familiar mushrooms. These organisms are classified as one of the traditional eukaryotic kingdoms, along with Animalia, Plantae, and either Protista or Protozoa and Chromista. A characteristic that places fungi in a different kingdom from plants, bacteria, and some protists is chitin in their cell walls. Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize. Growth is their means of mobility, except for spores (a few of which are flagellated), which may travel through the air or water. Fungi are the principal decomposers in ecological systems. These and other differences place fungi in a single group of related organisms, named the ''Eumycota'' (''true fungi'' or ''Eum ...

Ustilaginomycotina
The Ustilaginomycotina is a subdivision within the division Basidiomycota of the kingdom Fungi. It consists of the classes Ustilaginomycetes and Exobasidiomycetes, and in 2014 the subdivision was reclassified and the two additional classes Malasseziomycetes and Monilielliomycetes added. The name was first published by Doweld in 2001; Bauer and colleagues later published it in 2006 as an isonym. Ustilagomycotina and Agaricomycotina are considered to be sister groups, and they are in turn sister groups to the subdivision Pucciniomycotina. Ustilaginomycotina comprises 115 genera with more than 1700 species. The subdivision is mostly plant parasites on vascular plants, and the distribution of the subdivision is therefore restricted to the distribution of the host. The group is also called the true smut fungi because of the production of teliospores. The name smut is still used as a term since it circumscribes the organization and life cycle of Ustilaginomycotina, but it is not ...
