Aegopodium Podagraria
''Aegopodium podagraria'', commonly called ground elder, is a species of flowering plant in the carrot family Apiaceae that grows in shady places. The name "ground elder" comes from the superficial similarity of its leaves and flowers to those of elder (''Sambucus''), which is not closely related. Other common names include herb gerard, bishop's weed, goutweed, gout wort, snow-in-the-mountain, English masterwort and wild masterwort. It is the type species of the genus '' Aegopodium''. It is native to Europe and Asia, but has been introduced around the world as an ornamental plant, where it occasionally poses an ecological threat as an invasive exotic plant. Description This herbaceous perennial grows to a height of from underground rhizomes. The stems are erect, hollow, and grooved. The upper leaves are ternate, broad and toothed. It flowers in spring and early summer. Numerous flowers are grouped together in an umbrella-shaped flowerhead known as a compound umbel. The main umb ...

Soil Seed Bank
The soil seed bank is the natural storage of seeds, often dormant, within the soil of most ecosystems. The study of soil seed banks started in 1859 when Charles Darwin observed the emergence of seedlings using soil samples from the bottom of a lake. The first scientific paper on the subject was published in 1882 and reported on the occurrence of seeds at different soil depths. Weed seed banks have been studied intensely in agricultural science because of their important economic impacts; other fields interested in soil seed banks include forest regeneration and restoration ecology. Background Many taxa have been classified according to the longevity of their seeds in the soil seed bank. Seeds of ''transient'' species remain viable in the soil seed bank only to the next opportunity to germinate, while seeds of ''persistent'' species can survive longer than the next opportunity—often much longer than one year. Species with seeds that remain viable in the soil longer than ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dot Moth
The dot moth (''Melanchra persicariae'') is a moth of the family Noctuidae. The species was first described by Carl Linnaeus in 1761. It is a very distinctive species with very dark brown, almost black, forewings marked with a large white stigma from which the species gets its common name. The hindwings are grey with a dark band at the termen. The wingspan is 38–50 mm. It flies at night in July and August and is attracted to light, sugar and flowers. Distribution The distribution area ranges from Spain in the west to Korea and Japan. It is found throughout Europe apart from the south-east. To the north it is found in Scotland and southern Fennoscandia, east through southern Russia, the Russian Far East and Siberia and Central Asia to the Kamchatka Peninsula. Then northern China to Korea and Japan. The southern boundary runs through northern Spain, Italy (except for Sicily), Macedonia, Bulgaria, Asia Minor, the southern Caucasus, northern Iran. In the Alps it rises up to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidoptera
Lepidoptera ( ) is an order of insects that includes butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most speciose orders, along with the Hymenoptera, Diptera, and Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scales that cover the bodies, wings, and a proboscis. 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 mem ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The 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. 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 larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are ...

Ornamental Plant
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Glyphosate
Glyphosate (IUPAC name: ''N''-(phosphonomethyl)glycine) is a broad-spectrum systemic herbicide and crop desiccant. It is an organophosphorus compound, specifically a phosphonate, which acts by inhibiting the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase. It is used to kill weeds, especially annual broadleaf weeds and grasses that compete with crops. Its herbicidal effectiveness was discovered by Monsanto chemist John E. Franz in 1970. Monsanto brought it to market for agricultural use in 1974 under the trade name Roundup. Monsanto's last commercially relevant United States patent expired in 2000. Farmers quickly adopted glyphosate for agricultural weed control, especially after Monsanto introduced glyphosate-resistant Roundup Ready crops, enabling farmers to kill weeds without killing their crops. In 2007, glyphosate was the most used herbicide in the United States' agricultural sector and the second-most used (after 2,4-D) in home and garden, government and ...

Wild Type
The wild type (WT) is the phenotype of the typical form of a species as it occurs in nature. Originally, the wild type was conceptualized as a product of the standard "normal" allele at a locus, in contrast to that produced by a non-standard, "mutant" allele. "Mutant" alleles can vary to a great extent, and even become the wild type if a genetic shift occurs within the population. Continued advancements in genetic mapping technologies have created a better understanding of how mutations occur and interact with other genes to alter phenotype. It is now appreciated that most or all gene loci exist in a variety of allelic forms, which vary in frequency throughout the geographic range of a species, and that a uniform wild type does not exist. In general, however, the most prevalent allele – i.e., the one with the highest gene frequency – is the one deemed wild type. The concept of wild type is useful in some experimental organisms such as fruit flies ''Drosophila melanogaster'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aegopodium Podagraria-(dkrb)-1
''Aegopodium'' is a plant genus of the family Apiaceae native to Europe and western Asia. It is represented by about seven species, all are perennial herbs. Flowers are compounded, umbels appearing in spring-summer and are visited by many types of insect pollinators. Fruit consists of two-winged or ribbed nuts that separate on ripening. The most well-known member is the ''Aegopodium podagraria'', the ground elder also known as snow-on-the-mountain, Bishop's weed, goutweed, native to Europe and Asia. It is variegated green and white that sometimes reverts to solid green within a patch. Small, white, five-petal flowers are held about three feet high, above the leaves, in flat topped clusters. Underground are long white branching rhizomes that vaguely resemble quackgrass. Regarded as an ecological threat, goutweed is aggressive, invasive and forms dense patches reducing species diversity in the ground layer. On the other hand, because of this, it is often used as a low maintenance gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
