Shepherdia Weaveri
''Shepherdia'', commonly called buffaloberry or bullberry, is a genus of small shrubs in the Elaeagnaceae family. The plants are native to northern and western North America. They are non-legume nitrogen fixers. ''Shepherdia'' is dioecious, with male and female flowers produced on separate plants. Species The genus has three living species: *''Shepherdia argentea'' - silver buffaloberry *''Shepherdia canadensis'' - Canada buffaloberry *'' Shepherdia rotundifolia'' - roundleaf buffaloberry, endemic to southern Utah and northern Arizona An additional extinct species is also placed in the genus: *†'' Shepherdia weaveri'' - Paleocene/Eocene Kachemak Bay, Alaska Fruit The berry is recognizable by being a dark shade of red, with little white dots on them. They are rough to the touch, and are found on both trees and shrubs. Wildlife The plants have rather bitter-tasting berries. The fruit are often eaten by bears, which by legend, prefer the berries to maintain fat stores durin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an English botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near Settle in the West Riding of Yorkshire and spent some years as an apprentice printer in England. Soon after going to the United States he met professor Benjamin Smith Barton in Philadelphia. Barton encouraged his strong interest in natural history. Early explorations in the United States In 1810 he travelled to the Great Lakes and in 1811 travelled on the Astor Expedition led by William Price Hunt on behalf of John Jacob Astor up the Missouri River. Nuttall was accompanied by the English botanist John Bradbury, who was collecting plants on behalf of Liverpool botanical gardens. Nuttall and Bradbury left the party at the trading post with the Arikara Indians in South Dakota, and continued farther upriver with Ramsay Crooks. In August they returned to the Arikara post and jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Society Of America
The Geological Society of America (GSA) is a nonprofit organization dedicated to the advancement of the geosciences. History The society was founded in Ithaca, New York, in 1888 by Alexander Winchell, John J. Stevenson, Charles H. Hitchcock, John R. Procter and Edward Orton and has been headquartered at 3300 Penrose Place, Boulder, Colorado, US, since 1967. GSA began with 100 members under its first president, James Hall. In 1889 Mary Emilie Holmes became its first female member. It grew slowly but steadily to 600 members until 1931, when a nearly $4 million endowment from 1930 president R. A. F. Penrose Jr. jumpstarted GSA's growth. As of December 2017, GSA had more than 25,000 members in over 100 countries. The society has six regional sections in North America, three interdisciplinary interest groups, and eighteen specialty divisions. Activities The stated mission of GSA is "to advance geoscience research and discovery, service to society, stewardship of Ear ...

Flora Of Northern America
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Dioecious Plants
Dioecy ( ; ; adj. dioecious, ) is a characteristic of certain species that have distinct unisexual individuals, each producing either male or female gametes, either directly (in animals) or indirectly (in seed plants). Dioecious reproduction is biparental reproduction. Dioecy has costs, since only the female part of the population directly produces offspring. It is one method for excluding self-fertilization and promoting allogamy (outcrossing), and thus tends to reduce the expression of recessive deleterious mutations present in a population. Plants have several other methods of preventing self-fertilization including, for example, dichogamy, herkogamy, and self-incompatibility. In zoology In zoology, dioecy means that an animal is either male or female, in which case the synonym gonochory is more often used. Most animal species are gonochoric, almost all vertebrate species are gonochoric, and all bird and mammal species are gonochoric. Dioecy may also describe colonies ...

Rosales Genera
Rosales (, ) are an order of flowering plants. Peter F. Stevens (2001 onwards). "Rosales". At: Trees At: Angiosperm Phylogeny Website. At: Missouri Botanical Garden Website. (see ''External links'' below) Well-known members of Rosales include: roses, strawberries, blackberries and raspberries, apples and pears, plums, peaches and apricots, almonds, rowan and hawthorn, jujube, elms, banyans, figs, mulberries, breadfruit, nettles, hops, and cannabis. Rosales contain about 7,700 species, distributed into nine families and about 260 genera. Their type family is the rose family, Rosaceae. The largest families are Rosaceae (91/4828) and Urticaceae (53/2625). Taxonomy The order Rosales is strongly supported as monophyletic in phylogenetic analyses of DNA sequences, such as those carried out by members of the Angiosperm Phylogeny Group.Walter S. Judd, Christopher S. Campbell, Elizabeth A. Kellogg, Peter F. Stevens, and Michael J. Donoghue. 2008. ''Plant Systematics: A Phylogenetic ...

Cranberry Sauce
Cranberry sauce or cranberry jam is a sauce or relish made out of cranberries, commonly served as a condiment or a side dish with Thanksgiving dinner in North America and Christmas dinner in the United Kingdom and Canada. There are differences in flavor depending on the geography of where the sauce is made: in Europe it is generally slightly sour-tasting, while in North America it is typically more heavily sweetened. History The recipe for cranberry sauce appears in the 1796 edition of '' American Cookery'' by Amelia Simmons, the first known cookbook authored by an American. In 1606, the Mi'kmaq people introduced the French settlers in Port-Royal, Nova Scotia, to cranberries. They would have been sweetened with maple sugar and served at the settlers first Thanksgiving in North America that year. The settlers described eating what they called "small red apples" in letters sent back to France. Port-Royal reports contained menus describing cranberries. They are still called , ...

Ectropis Crepuscularia
The engrailed and small engrailed (''Ectropis crepuscularia'') are moths of the family Geometridae found from the British Isles through central and eastern Europe to the Russian Far East and Kazakhstan. The western Mediterranean and Asia Minor and the Caucasus represent the southern limit of the distribution (with the Balkan countries). In the north, the distribution area ends at the Arctic Circle. It also occurs in North America. Debate exists as to whether they make up one species, or whether ''E. crepuscularia'' actually refers only to the small engrailed, with the engrailed proper being separable as ''E. bistortata''. The ground colour of the wings is buff or grey, variably marked with darker fascia and a pale postdiscal crossline. The darker markings are not usually as strong as in the rather similar willow beauty. Melanic forms occur fairly frequently. The wingspan is . One or two broods are produced each year. In the British Isles, the adults can be seen at any time be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidoptera
Lepidoptera ( ) or lepidopterans is an order (biology), order of winged insects which includes butterflies and moths. About 180,000 species of the Lepidoptera have been described, representing 10% of the total described species of living organisms, making it the second largest insect order (behind Coleoptera) with 126 family (biology), families and 46 Taxonomic rank, superfamilies, and one of the most widespread and widely recognizable insect orders in the world. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, large triangular Insect wing, wings, and a proboscis for siphoning nectars. The scales are modified, flattened "hairs", and give butterflies and moths their wide variety of colors and patterns. Almost all species have some form of membranous wings, except for a few that have reduced wings or are wingless. Mating and the laying of eggs is normally performe ...

Larva
A larva (; : larvae ) is a distinct juvenile form many animals undergo before metamorphosis into their next life stage. Animals with indirect development such as insects, some arachnids, amphibians, or cnidarians typically have a larval phase of their life cycle. A larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. In the case of smaller primitive arachnids, the larval stage differs by having three instead of four pairs of legs. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the lar ...
