Rubus Pubescens
''Rubus pubescens'' (dwarf red blackberry, dwarf red raspberry, dewberry) is a herbaceous perennial widespread across much of Canada and the northern United States, from Alaska to Newfoundland, south as far as Oregon, Colorado, and West Virginia. Description Dewberry is known as a subshrub or herbaceous perennial (Kartesz 2011). The trailing stems ( stolons) are in length, and the upright petioles are usually less than 20 cm (8 inches) tall. They differ from larger shrubby species in the genus in that the only upright part is herbaceous and only lightly speckled with fine hairs (hence the specific epithet ''pubescens''), as opposed to the woody stems and larger prickles that cover many other species of ''Rubus'' Leaves are compound with three more or less sessile (stalk-less), diamond-shaped leaflets. The middle leaflet is the largest, and most symmetrical, while the two side leaflets are wider below the midrib; all leaflets have toothed margins. With the exception ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, Rosa'' and ''Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly colored tepals. Sinc ...

Red Raspberry
''Rubus idaeus'' (raspberry, also called red raspberry or occasionally European red raspberry to distinguish it from other raspberry species) is a red-fruited species of ''Rubus'' native to Europe and northern Asia and commonly cultivated in other temperate regions. Taxonomy A closely related plant in North America, sometimes regarded as the variety ''Rubus idaeus'' var. ''strigosus'', is more commonly treated as a distinct species, ''Rubus strigosus'' (American red raspberry), as is done here. Red-fruited cultivated raspberries, even in North America, are generally ''Rubus idaeus'' or horticultural derivatives of hybrids of ''R. idaeus'' and ''R. strigosus;'' these plants are all addressed in the present article. Description Plants of ''Rubus idaeus'' are generally perennials, which bear biennial stems ("canes") from a perennial root system. In its first year, a new, unbranched stem (" primocane") grows vigorously to its full height of 1.5–2.5 m (5.0–8.3 feet), bearing large ...

Insect-pollinated
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar; they may also have an attractive scent which in some cases mimics insect pheromones. Insect pollinators such as bees have adaptations for their role, such as lapping or sucking mouthparts to take in nectar, and in some species also pollen baskets on their hind legs. This required the coevolution of insects and flowering plants in the development of pollination behaviour by the insects and pollination mechanisms by the flowers, benefiting both groups. Coevolution History The early spermatophytes (seed plants) were largely dependent on the wind to carry their pollen from one plant to another. Prior to the appearance of flowering plants some gymnospe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grouse
Grouse are a group of birds from the order Galliformes, in the family Phasianidae. Grouse are presently assigned to the tribe Tetraonini (formerly the subfamily Tetraoninae and the family Tetraonidae), a classification supported by mitochondrial DNA sequence studies, and applied by the American Ornithologists' Union, ITIS, International Ornithological Congress, and others. Grouse inhabit temperate and subarctic regions of the Northern Hemisphere, from pine forests to moorland and mountainside, from 83°N (rock ptarmigan in northern Greenland) to 28°N (Attwater's prairie chicken in Texas). Turkeys are closely related to grouse and are also classified in the tribe Tetraonini. The koklass pheasant is also closely allied with them. Description Grouse are heavily built like other Galliformes, such as chickens. They range in length from , and in weight from . Males are larger than females—twice as heavy in the western capercaillie, the largest member of the family. Grouse ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...

Grizzly Bear
The grizzly bear (''Ursus arctos horribilis''), also known as the North American brown bear or simply grizzly, is a population or subspecies of the brown bear inhabiting North America. In addition to the mainland grizzly (''Ursus arctos horribilis''), other morphological forms of brown bear in North America are sometimes identified as grizzly bears. These include three living populations—the Kodiak bear (''U. a. middendorffi''), the Kamchatka bear (''U. a. beringianus''), and the peninsular grizzly (''U. a. gyas'')—as well as the extinct California grizzly (''U. a. californicus''†), Mexican grizzly (formerly ''U. a. nelsoni''†), and Ungava-Labrador grizzly (formerly ''U. a. ungavaesis''†). On average, grizzly bears near the coast tend to be larger while inland grizzlies tend to be smaller. The Ussuri brown bear (''U. a. lasiotus''), inhabiting Russia, Northern China, Japan, and Korea, is sometimes referred to as the "black grizzly", although it is no more closely ...

American Black Bear
The American black bear (''Ursus americanus''), also called simply a black bear or sometimes a baribal, is a medium-sized bear endemic to North America. It is the continent's smallest and most widely distributed bear species. American black bears are omnivores, with their diets varying greatly depending on season and location. They typically live in largely forested areas, but will leave forests in search of food, and are 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, due to 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 only two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution Despite living in North America, American black bears are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coptis Trifolia
''Coptis trifolia'', commonly known as the threeleaf goldthread or savoyane, is a perennial plant in the genus ''Coptis'', a member of the family Ranunculaceae. Distribution It is native to North America and Asia across the subarctic region. Its range is divided into three broad groups. The first is from southern Greenland and Labrador that extends to Manitoba to the west and to the mountains of North Carolina to the south. The second is in Alaska and adjacent areas of British Columbia, extending towards eastern Siberia and into Japan and Manchuria. It is also found in Norway and central Russia. The disrupted and wide range of the species suggests that the three populations have been isolated from each other for significant periods of time. Goldthread seems to prefer coniferous or mixed canopies dominated by Eastern hemlock, but it has also been found in deciduous canopies in moist, acidic soils. Description Goldthread has at least one small, deeply three-lobed, evergree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maianthemum Canadensis
''Maianthemum'' includes the former genus ''Smilacina'' and is a genus of perennial herbaceous flowering plants with fleshy, persistent rhizomes. It is widespread across much of North America, Europe and Asia, and may be terrestrial, aquatic or epiphytic. It is characterized by simple, unbranched stems that are upright, leaning or hanging down and have 2–17 foliage leaves. Leaves are simple and may clasp the stem or be short-petiolate. The inflorescence is terminal and either a panicle or a raceme with few to many pedicelate flowers. Most species have 6 tepals and 6 stamens; a few have parts in 4s. Tepals are distinct in most species and all of similar size. Flowers are spreading, cup-shaped or bell-shaped and usually white, but lavender to red or green in some species. Fruits are rounded to lobed berries containing few to several seeds. Vegetative ; Rhizomes and roots Rhizomes are persistent and have scale leaves. They can be sympodial; spreading and thread-like, or cylindr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornus Canadensis
''Cornus canadensis'' is a species of flowering plant in the dogwood family Cornaceae, native to eastern Asia and North America. Common names include Canadian dwarf cornel, Canadian bunchberry, quatre-temps, crackerberry, and creeping dogwood. Unlike its relatives, which are for the most part substantial trees and shrubs, ''C. canadensis'' is a creeping, rhizomatous perennial growing to about tall. Description ''Cornus canadensis'' is a slow-growing herbaceous perennial growing tall, generally forming a carpet-like mat. The above-ground shoots rise from slender creeping rhizomes that are placed deep in the soil, and form clonal colonies under trees. The vertically produced above-ground stems are slender and unbranched. Produced near the terminal node, the leaves are shiny dark green and arranged oppositely on the stem, clustered with six leaves that often seem to be in a whorl because the internodes are compressed. The leaves consist of two types: two larger and four smal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blackberry
The blackberry is an edible fruit produced by many species in the genus ''Rubus'' in the family Rosaceae, hybrids among these species within the subgenus ''Rubus'', and hybrids between the subgenera ''Rubus'' and ''Idaeobatus''. The taxonomy of blackberries has historically been confused because of hybridization and apomixis, so that species have often been grouped together and called species aggregates. For example, the entire subgenus ''Rubus'' has been called the ''Rubus fruticosus'' aggregate, although the species ''R. fruticosus'' is considered a synonym of '' R. plicatus''. ''Rubus armeniacus'' ("Himalayan" blackberry) is considered a noxious weed and invasive species in many regions of the Pacific Northwest of Canada and the United States, where it grows out of control in urban and suburban parks and woodlands. Description What distinguishes the blackberry from its raspberry relatives is whether or not the torus ( receptacle or stem) "picks with" (i.e., stays with) th ...
