Paleoflora Of The Eocene Okanagan Highlands
The paleoflora of the Eocene Okanagan Highlands includes all plant and fungi fossils preserved in the Eocene Okanagan Highlands ''Lagerstätten''. The highlands are a series of Early Eocene geological formations which span an transect of British Columbia, Canada and Washington state, United States and are known for the diverse and detailed plant fossils which represent an upland temperate ecosystem immediately after the Paleocene-Eocene thermal maximum, and before the increased cooling of the middle and late Eocene to Oligocene. The fossiliferous deposits of the region were noted as early as 1873, with small amounts of systematic work happening in the 1880-90s on British Columbian sites, and 1920-30s for Washington sites. A returned focus and more detailed descriptive work on the Okanagan Highlands sites revived in the 1970's. The noted richness of agricultural plant families in Republic and Princeton floras resulted in the term "Eocene orchards" being used for the paleofloras. ...

Cherries
A cherry is the fruit of many plants of the genus ''Prunus'', and is a fleshy drupe (stone fruit). Commercial cherries are obtained from cultivars of several species, such as the sweet ''Prunus avium'' and the sour ''Prunus cerasus''. The name 'cherry' also refers to the cherry tree and its wood, and is sometimes applied to almonds and visually similar flowering trees in the genus ''Prunus'', as in " ornamental cherry" or "cherry blossom". Wild cherry may refer to any of the cherry species growing outside cultivation, although ''Prunus avium'' is often referred to specifically by the name "wild cherry" in the British Isles. Botany True cherries ''Prunus'' subg. ''Cerasus'' contains species that are typically called cherries. They are known as true cherries and distinguished by having a single winter bud per axil, by having the flowers in small corymbs or umbels of several together (occasionally solitary, e.g. ''P. serrula''; some species with short racemes, e.g. '' P. ...

Horsefly, British Columbia
Horsefly is an unincorporated community on the northwest shore of the Horsefly River, in the Cariboo region of central British Columbia. The location, via BC Highway 97, Likely Rd, and Horsefly Rd, is about northeast of Williams Lake, and by road south of Quesnel Lake. Mining Peter Dunlevey's party of prospectors is credited with the first discovery of gold in the Cariboo Gold Rush near the site of the present village. However, evidence indicates H.O. Bowe's party arrived weeks earlier to the Horsefly River in the summer of 1859. That year, at least four separate groups found gold. During the following years, small placer operations existed. In 1884, Thaddeus Harper obtained sizable mining leases, but his operations from 1886 to 1888 were unsuccessful. In 1891, R.T. Ward, who had bought or leased the Harper claims, found paying ground. Called the Horsefly Gold Mining Co., activities continued until 1902. From 1891, the Miocene Gravel Mining Co undertook underground hard-rock mi ...

Horsefly Shales
Horse-flies or horseflies are true flies in the family Tabanidae in the insect order Diptera. They are often large and agile in flight, and only the female horseflies bite animals, including humans, to obtain blood. They prefer to fly in sunlight, avoiding dark and shady areas, and are inactive at night. They are found all over the world except for some islands and the polar regions (Hawaii, Greenland, Iceland). Both horse-flies and botflies (Oestridae) are sometimes referred to as gadflies. Adult horse-flies feed on nectar and plant exudates; the males have weak mouthparts and only the females bite animals to obtain enough protein from blood to produce eggs. The mouthparts of females are formed into a stout stabbing organ with two pairs of sharp cutting blades, and a spongelike part used to lap up the blood that flows from the wound. The larvae are predaceous and grow in semiaquatic habitats. Female horse-flies can transfer blood-borne diseases from one animal to another ...

Quesnel, British Columbia
Quesnel (Kee-nel in French) is a city located in the Cariboo Regional District of British Columbia, Canada. Located nearly evenly between the cities of Prince George and Williams Lake, it is on the main route to northern British Columbia and the Yukon. Quesnel is located at the confluence of the Fraser River and Quesnel River. Quesnel's metropolitan area has a population of 23,146 making it the largest urban center between Prince George and Kamloops. Quesnel is a sister city to Shiraoi, Japan. Quesnel hosted the 2000 British Columbia Winter Games, a biennial provincial amateur sports competition. To the east of Quesnel is Wells, Barkerville, and Bowron Lake Provincial Park, a popular canoeing destination in the Cariboo Mountains. History Long before the arrival of prospectors during the Cariboo Gold Rush of 1862, the Southern Carrier (Dakelh) people lived off the land around Quesnel, occupying the area from the Bowron Lakes in the east to the upper Blackwater River and Dean ...

Smithers, British Columbia
Smithers is a town in northwestern British Columbia, approximately halfway between Prince George and Prince Rupert. With a population of 5,351 in 2016, Smithers provides service coverage for most of the Bulkley Valley. History Region First Nations settlements existed thousands of years prior to European presence. Railway The planned Grand Trunk Pacific Railway (GTP) required two major divisional points in BC, where additional staff and facilities would be located. After Prince George, various central points on the Prince Rupert leg were considered in the vicinity of Aldermere. A prime choice was Hubert, east of Telkwa, initially called Bulkley by the developers, who had amassed the surrounding land. These speculators promoted a future new city, and later a trade centre of the Bulkley Valley, both fallacious claims, since Smithers had already been selected as the divisional point. The Interior News of Aldermere had earlier adopted a policy of refusing advertising from such unsc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Driftwood Canyon Provincial Park
Driftwood Canyon Provincial Park is a provincial park in British Columbia, Canada. Driftwood Canyon Provincial Park covers 23 ha of the Bulkley River Valley, on the east side of Driftwood Creek, a tributary of the Bulkley River, 10 km northeast of the town of Smithers. The park is accessible from Driftwood Road from Provincial Highway 16. It was created in 1967 by the donation of the land by the late Gordon Harvey (1913–1976) to protect fossil beds on the east side of Driftwood Creek. The beds were discovered around the beginning of the 20th century. The park lands are part of the asserted traditional territory of the Wet'suwet'en First Nation.Ludvigsen, R. 2001.

Compression Fossil
A compression fossil is a fossil preserved in sedimentary rock that has undergone physical compression. While it is uncommon to find animals preserved as good compression fossils, it is very common to find plants preserved this way. The reason for this is that physical compression of the rock often leads to distortion of the fossil. The best fossils of leaves are found preserved in fine layers of sediment that have been compressed in a direction perpendicular to the plane of the deposited sediment. Since leaves are basically flat, the resulting distortion is minimal. Plant stems and other three-dimensional plant structures do not preserve as well under compression. Typically, only the basic outline and surface features are preserved in compression fossils; internal anatomy is not preserved. These fossils may be studied while still partially entombed in the sedimentary rock matrix where they are preserved, or once lifted out of the matrix by a peel or transfer technique. Compr ...

Hybridization (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show Heterosis, hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductive isolation, reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhus
Sumac ( or ), also spelled sumach, is any of about 35 species of flowering plants in the genus ''Rhus'' and related genera in the cashew family (Anacardiaceae). Sumacs grow in subtropical and temperate regions throughout the world, including East Asia, Africa, and North America. Sumac is used as a spice, as a dye, and in medicine. Description Sumacs are dioecious shrubs and small trees in the family Anacardiaceae that can reach a height of . The leaves are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes long, each flower very small, greenish, creamy white or red, with five petals. The fruits are reddish, thin-fleshed drupes covered in varying levels of hairs at maturity and form dense clusters at branch tips, sometimes called sumac bobs. Sumacs propagate both by seed (spread by birds and other animals through their droppings), and by new shoots from rhizomes, forming large clonal colonies. Taxonomy ...
