Chittem Ram Mohan Reddy
''Frangula purshiana'' (cascara, cascara buckthorn, cascara sagrada, bearberry, and in the Chinook Jargon, chittem stick and chitticum stick; syn. ''Rhamnus purshiana'') is a species of plant in the family Rhamnaceae. It is native to western North America from southern British Columbia south to central California, and eastward to northwestern Montana. The dried bark of cascara was used as a laxative in folk medicine by the indigenous peoples of the Pacific Northwest, and later worldwide in conventional medicines until 2002. Description Cascara is a large shrub or small tree tall, with a trunk in diameter. The buds have no scales, unique for the northwest region. The thin bark is brownish to silver-gray with light splotching (often, in part, from lichens); the inner bark is smooth and yellowish (turning dark brown with age and/or exposure to sunlight). Cascara bark has an intensely bitter flavor that will remain in the mouth for hours, overpowering and even numbing the taste ...

Chinook Jargon
Chinook Jargon (' or ', also known simply as ''Chinook'' or ''Jargon'') is a language originating as a pidgin language, pidgin trade language in the Pacific Northwest. It spread during the 19th century from the lower Columbia River, first to other areas in modern Oregon and Washington (state), Washington, then to British Columbia and parts of Alaska, Northern California, Idaho and Montana. It sometimes took on the characteristics of a creole language. The contact language Chinook Jargon should not be confused with the Indigenous language Chinookan languages, Chinook. Reflecting its origins in early trade transactions, approximately 15 percent of its lexicon is French. It also makes use of English loan words and those of other language systems. Its entire written form is in the Duployan shorthand developed by French priest Émile Duployé. Many words from Chinook Jargon remain in common use in the Western United States and British Columbia. It has been described as part of a multi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drupe
In botany, a drupe (or stone fruit) is a type of fruit in which an outer fleshy part (exocarp, or skin, and mesocarp, or flesh) surrounds a single shell (the ''pip'' (UK), ''pit'' (US), ''stone'', or ''pyrena'') of hardened endocarp with a seed (''kernel'') inside. Drupes do not split open to release the seed, i.e., they are dehiscence (botany), indehiscent. These fruits usually develop from a single carpel, and mostly from flowers with Superior ovary, superior ovaries (polypyrenous drupes are exceptions). The definitive characteristic of a drupe is that the hard, woody (lignified) stone is derived from the Ovary (botany), ovary wall of the flower. In an aggregate fruit, which is composed of small, individual drupes (such as a raspberry), each individual is termed a drupelet, and may together form an aggregate fruit. Such fruits are often termed ''berries'', although botanists use a Berry (botany), different definition of ''berry''. Other fleshy fruits may have a stony enclosur ...

Fire Regime
A fire regime is the pattern, frequency, and intensity of the bushfires and wildfires that prevail in an area over long periods of time. It is an integral part of fire ecology, and renewal for certain types of ecosystems. A fire regime describes the spatial and temporal patterns and ecosystem impacts of fire on the landscape, and provides an integrative approach to identifying the impacts of fire at an ecosystem or landscape level.Morgan, Penelope; Hardy; Swetnam; Rollins; Long (1999)"Mapping fire regimes across time and space: Understanding coarse and fine-scale fire patterns"(PDF). '' International Journal of Wildland Fire''. 10: 329–342 – via Google Scholar. If fires are too frequent, plants may be killed before they have matured, or before they have set sufficient seed to ensure population recovery. If fires are too infrequent, plants may mature, senesce, and die without ever releasing their seed. Fire regimes can change with the spatial and temporal variations in topograph ...

Shade Tolerant
In ecology, shade tolerance is a plant's ability to tolerate low light levels. The term is also used in horticulture and landscaping, although in this context its use is sometimes imprecise, especially in labeling of plants for sale in nursery (horticulture), commercial nurseries. Shade tolerance is a complex, multi-faceted property of plants. Different plant species exhibit different adaptations to shade (shadow), shade, and a particular plant can exhibit varying degrees of shade tolerance, or even of requirement for light, depending on its history or stage of development. Basic concepts Except for some parasitic plants, all land plants need sunlight to survive. However, in general, more sunlight does not always make it easier for plants to survive. In direct sunlight, plants face desiccation and exposure to UV rays, and must expend energy producing pigments to block UV light, and waxy coatings to prevent water loss. Plants adapted to shade have the ability to use far-red light ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ring-tailed Cat
The ringtail (''Bassariscus astutus'') is a mammal of the raccoon family native to arid regions of North America. It is widely distributed and well-adapted to its distributed areas. It has been legally trapped for its fur. Globally, it is listed as Least Concern on the IUCN Red List but is a Conservation Strategy Species in Oregon and Fully Protected in California The species is known by a variety of names, such as ring-tailed cat, miner's cat, civet cat, and cacomistle (or cacomixtle), though the last of these can refer to '' B. sumichrasti''. The ringtail is the state mammal of Arizona. Description The ringtail is black to dark brown in color with pale underparts. The animal has a pointed muzzle with long whiskers, similar to that of a fox (its Latin name means 'clever little fox') and its body resembles that of a cat. The ringtail's face resembles a mask as dark brown and black hair surround its eyes. These animals are characterized by a long black and white "ringed" ta ...

Raccoon
The raccoon ( or , ''Procyon lotor''), sometimes called the North American, northern or common raccoon (also spelled racoon) to distinguish it from Procyonina, other species of raccoon, is a mammal native to North America. It is the largest of the procyonid family, having a body length of , and a body weight of . Its grayish coat mostly consists of dense underfur, which insulates it against cold weather. The animal's most distinctive features include its extremely dexterous front paws, its facial mask, and its ringed tail, which are common themes in the mythologies of the Indigenous peoples of the Americas surrounding the species. The raccoon is noted for its animal cognition, intelligence, and studies show that it can remember the solution to tasks for at least three years. It is usually nocturnal and omnivorous, eating about 40% invertebrates, 33% plants, and 27% vertebrates. The original habitats of the raccoon are deciduous and temperate broadleaf and mixed forests, mixed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gray Fox
The gray fox (''Urocyon cinereoargenteus''), or grey fox, is an omnivorous mammal of the family Canidae, widespread throughout North America and Central America. This species and its only congener (biology), congener, the diminutive island fox (''Urocyon littoralis'') of the California Channel Islands of California, Channel Islands, are the only living members of the genus ''Urocyon'', which is considered to be genetically Sister group, sister to all other living canids. Its Specific name (zoology), species name ''cinereoargenteus'' means ":wikt:cinereus, ashen silver". It was once the most common fox in the eastern United States, and though still found there, human advancement and deforestation allowed the red fox to become the predominant Canidae, fox-like canid. Despite this post-colonial competition, the gray fox has been able to thrive in urban and suburban environments, one of the best examples being South Florida, southern Florida.

Olympic Black Bear
The American black bear (''Ursus americanus''), or simply black bear, is a species of medium-sized bear which is Endemism, endemic to North America. It is the continent's smallest and most widely distributed bear species. It is an omnivore, with a diet varying greatly depending on season and location. It typically lives in largely forested areas; it will leave forests in search of food and is sometimes attracted to human communities due to the immediate availability of food. The International Union for Conservation of Nature (IUCN) lists the American black bear as a least-concern species because of its widespread distribution and a large population, estimated to be twice that of all other bear species combined. Along with the brown bear (''Ursus arctos''), it is one of the two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution The American black bear is not closely related to the brown bear or polar bear, though all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
