Bombus Rufocinctus
''Bombus rufocinctus'' is a species of bumblebee known commonly as the "red-belted bumblebee."NatureServe. 2015''Bombus rufocinctus''.NatureServe Explorer Version 7.1. Accessed 10 March 2016. It is native to North America where it has a wide distribution across Canada and the western, midwestern, and northeastern United States. It may occur in Mexico. The queen is 1.6 to 1.8 centimeters long and just under a centimeter wide at the abdomen. It is black with scattered gray and yellowish hairs on the head. The abdomen has many bright yellow hairs and areas of reddish hairs. The worker is 1.1 to 1.2 centimeters long and half a centimeter wide at the abdomen. It is similar to the queen but it may have longer hairs. The male is 1.2 to 1.3 centimeters long and half a centimeter wide at the abdomen. It is mostly black with more yellow on the head and abdomen. This species displays four genetically controlled color polymorphisms: the second and third abdominal terga may have red or black ...

Bombus Rufocinctus F
A bumblebee (or bumble bee, bumble-bee, or humble-bee) is any of over 250 species in the genus ''Bombus'', part of Apidae, one of the bee families. This genus is the only extant group in the tribe Bombini, though a few extinct related genera (e.g., ''Calyptapis'') are known from fossils. They are found primarily in higher altitudes or latitudes in the Northern Hemisphere, although they are also found in South America, where a few lowland tropical species have been identified. European bumblebees have also been introduced to New Zealand and Tasmania. Female bumblebees can sting repeatedly, but generally ignore humans and other animals. Most bumblebees are social insects that form colonies with a single queen. The colonies are smaller than those of honey bees, growing to as few as 50 individuals in a nest. Cuckoo bumblebees are brood parasitic and do not make nests or form colonies; their queens aggressively invade the nests of other bumblebee species, kill the resident quee ...

North America
North America is a continent in the Northern Hemisphere and almost entirely within the Western Hemisphere. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the southeast by South America and the Caribbean Sea, and to the west and south by the Pacific Ocean. Because it is on the North American Plate, North American Tectonic Plate, Greenland is included as a part of North America geographically. North America covers an area of about , about 16.5% of Earth's land area and about 4.8% of its total surface. North America is the third-largest continent by area, following Asia and Africa, and the list of continents and continental subregions by population, fourth by population after Asia, Africa, and Europe. In 2013, its population was estimated at nearly 579 million people in List of sovereign states and dependent territories in North America, 23 independent states, or about 7.5% of the world's population.

Polymorphism (biology)
In biology, polymorphism is the occurrence of two or more clearly different morphs or forms, also referred to as alternative ''phenotypes'', in the population of a species. To be classified as such, morphs must occupy the same habitat at the same time and belong to a panmictic population (one with random mating). Ford E.B. 1965. ''Genetic polymorphism''. Faber & Faber, London. Put simply, polymorphism is when there are two or more possibilities of a trait on a gene. For example, there is more than one possible trait in terms of a jaguar's skin colouring; they can be light morph or dark morph. Due to having more than one possible variation for this gene, it is termed 'polymorphism'. However, if the jaguar has only one possible trait for that gene, it would be termed "monomorphic". For example, if there was only one possible skin colour that a jaguar could have, it would be termed monomorphic. The term polyphenism can be used to clarify that the different forms arise from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichorium
''Cichorium'' is a genus of plants in the tribe Cichorieae within the family Asteraceae. The genus includes two cultivated species commonly known as chicory or endive, plus several wild species. Common chicory (''Cichorium intybus'') is a bushy perennial herb with blue or lavender (or, rarely, white or pink) flowers. It grows as a wild plant on roadsides in its native Europe, and in North America, where it has become naturalized. It is grown for its leaves, when it is known as leaf chicory, endive, radicchio, Belgian endive, French endive, or witloof. Other varieties are grown for their roots, which are used as a coffee substitute, similar to dandelion coffee. True endive (''Cichorium endivia'') is a species grown and used as a salad green. It has a slightly bitter taste. Curly endive and the broad-leafed escarole are true endives. ''Cichorium'' is used as a food plant by the larvae of some Lepidoptera species including setaceous Hebrew character, turnip moth, and the g ...

Eupatorium
''Eupatorium'' is a genus of flowering plants in the family Asteraceae, containing from 36 to 60 species depending on the classification system. Most are herbaceous perennials growing to tall. A few are shrubs. The genus is native to temperate regions of the Northern Hemisphere. Most are commonly called bonesets, thoroughworts or snakeroots in North America. The genus is named for Mithridates Eupator, king of Pontus. Systematics and taxonomy ''Eupatorium'' has at times been held to contain as many as 800 species, but many of these have been moved (at least by some authors) to other genera, including '' Ageratina'', ''Chromolaena'', ''Condylidium'', ''Conoclinium'', ''Critonia'', '' Cronquistianthus'', '' Eutrochium'', ''Fleischmannia'', ''Flyriella'', ''Hebeclinium'', ''Koanophyllon'', ''Mikania'', and ''Tamaulipa''. The classification of the tribe Eupatorieae, including species placed in ''Eupatorium'' in the present or past, is an area of ongoing research, so further chang ...

Fragaria
''Fragaria'' () is a genus of flowering plants in the rose family, Rosaceae, commonly known as strawberries for their edible fruits. There are more than 20 described species and many hybrids and cultivars. The most common strawberries grown commercially are cultivars of the garden strawberry, a hybrid known as ''Fragaria'' × ''ananassa''. Strawberries have a taste that varies by cultivar, and ranges from quite sweet to rather tart. Strawberries are an important commercial fruit crop, widely grown in all temperate regions of the world. Description Strawberries are not berries in the botanical sense.Esau, K. 1977. ''Anatomy of seed plants''. John Wiley and Sons, New York. The fleshy and edible part of the "fruit" is a receptacle, and the parts that are sometimes mistakenly called "seeds" are achenes and therefore the true botanical fruits. Etymology The genus name derives from ("strawberry") and , a suffix used to create feminine nouns and plant names. The Latin name is tho ...

Grindelia
''Grindelia'' (gumweed) is a genus of plants native to the Americas belonging to the family Asteraceae. The genus was named for Latvian botanist David Hieronymus Grindel, 1776–1836. They are herbaceous plants or subshrubs with annual, biennial, or perennial life cycles. The flowerheads are composed of numerous yellow disc florets (usually between 100–200) and from zero to sixty or more yellow or orange ray florets. ''Grindelia squarrosa'', a plant with bright yellow flowers indigenous to much of the United States, is commonly called curlycup gumweed. ''Grindelia robusta'', found in the western states, is a coastal scrub bush that is reputed to have several medicinal uses. Hairy gumweed, '' Grindelia cuneifolia'', occurs in brackish coastal marshes of western North America, such as in some portions of the San Francisco Bay perimeter. The genus is native to South America, Mexico, and western North America, though some species have been introduced and naturalized in eastern North ...

Helianthus
''Helianthus'' () is a genus comprising about 70 species of annual and perennial flowering plants in the daisy family Asteraceae commonly known as sunflowers. Except for three South American species, the species of ''Helianthus'' are native to North America and Central America. The best-known species is the common sunflower (''Helianthus annuus''), whose round flower heads in combination with the ligules look like the Sun. This and other species, notably Jerusalem artichoke (''H. tuberosus''), are cultivated in temperate regions and some tropical regions, as food crops for humans, cattle, and poultry, and as ornamental plants. The species ''H. annuus'' typically grows during the summer and into early fall, with the peak growth season being mid-summer. Several perennial ''Helianthus'' species are grown in gardens, but have a tendency to spread rapidly and can become aggressive. On the other hand, the whorled sunflower, ''Helianthus verticillatus'', was listed as an endangere ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goldenrod
Goldenrod is a common name for many species of flowering plants in the sunflower family, Asteraceae, commonly in reference to the genus '' Solidago''. Several genera, such as '' Euthamia'', were formerly included in a broader concept of the genus ''Solidago''. Some authors treat ''Oligoneuron'', the flat-topped goldenrods, as a separate genus than ''Solidago'', while others consider it a section: ''Solidago'' sect. ''Ptarmicoidei''. Goldenrods can be used as a sustainable method to enrich soil with nitrogen. With an increase of nitrogen levels, there can then be an increase of vegetative growth. Plants known as goldenrods include: *'' Bigelowia'' spp., rayless goldenrods, 2 species native to the Southeastern United States *'' Cuniculotinus gramineus'', Panamint rock goldenrod *'' Euthamia'' spp., flat-topped goldenrods or grass-leaved goldenrods, 5 species native to North America *'' Gundlachia triantha'', Trans-Pecos desert goldenrod *''Lorandersonia microcephala'', smal ...

Clover
Clover or trefoil are common names for plants of the genus ''Trifolium'' (from Latin ''tres'' 'three' + ''folium'' 'leaf'), consisting of about 300 species of flowering plants in the legume or pea family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to 30 cm tall. The leaves are trifoliate (rarely quatrefoiled; see four-leaf clover), monofoil, bifoil, cinquefoil, hexafoil, septfoil, etcetera, with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include '' Melilotus'' (sweet clover) and ''Medicago'' ( alfalfa or Calvar ...
