Tyrophagus Longior
''Tyrophagus longior'' is a mite in the family Acaridae. Description ''Tyrophagus longior'' is oval in shape and whitish to semitransparent in colour. It is covered dorsally in barbed setae. There are eight legs (six in larvae) that are light brown in colour. Adult females of ''T. longior'' can be distinguished from others of the genus by the following: prodorsal shield without pigmented eyespots; hysterosomal setae ''d1'' about 1.3–1.8× as long as ''c1'' and ''d2'', and the alveoli (bases) of ''d1'' situated approximately midway between those of ''c1'' and ''e1;'' and tarsi I and II with solenidia that are long and slender (not expanded at the tips). Adult males similarly lack pigmented eyespots and have long, slender solenidia. Males also have a large and slender aedeagus (male reproductive organ). Life cycle Like other species of ''Tyrophagus'', ''T. longior'' has a life cycle consisting of egg, larva, protonymph, tritonymph, and adult. Habitat These mites have bee ...

Mite
Mites are small arachnids (eight-legged arthropods) of two large orders, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari. However, most recent genetic analyses do not recover the two as each other's closest relative within Arachnida, rendering the group invalid as a clade. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others are Predation, predators or Parasitism, parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy Mites are not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird Nest
A bird nest is the spot in which a bird lays and Avian incubation, incubates its Bird egg, eggs and raises its young. Although the term popularly refers to a specific structures built by animals, structure made by the bird itself—such as the grassy cup nest of the American robin or Eurasian blackbird, or the elaborately woven hanging nest of the Montezuma oropendola or the village weaver—that is too restrictive a definition. For some species, a nest is simply a shallow depression made in sand; for others, it is the knot-hole left by a broken branch, a burrow dug into the ground, a chamber drilled into a tree, an enormous rotting pile of vegetation and earth, a shelf made of dried saliva or a mud dome with an entrance tunnel. The smallest bird nests are those of some hummingbirds, tiny cups which can be a mere across and high. At the other extreme, some nest mounds built by the dusky scrubfowl measure more than in diameter and stand nearly tall. The study of birds' nests ...

Phylogenetics
In biology, phylogenetics () is the study of the evolutionary history of life using observable characteristics of organisms (or genes), which is known as phylogenetic inference. It infers the relationship among organisms based on empirical data and observed heritable traits of DNA sequences, protein amino acid sequences, and morphology. The results are a phylogenetic tree—a diagram depicting the hypothetical relationships among the organisms, reflecting their inferred evolutionary history. The tips of a phylogenetic tree represent the observed entities, which can be living taxa or fossils. A phylogenetic diagram can be rooted or unrooted. A rooted tree diagram indicates the hypothetical common ancestor of the taxa represented on the tree. An unrooted tree diagram (a network) makes no assumption about directionality of character state transformation, and does not show the origin or "root" of the taxa in question. In addition to their use for inferring phylogenetic pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitochondrial DNA
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondrion, mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It als ...

Consolida Ajacis
''Consolida ajacis'' (doubtful knight's spur or rocket larkspur) is an Annual plant, annual flowering plant of the family Ranunculaceae native to Eurasia. It is widespread in other areas, including much of North America, where it is an introduced species. It is frequently grown in gardens as an Ornamental plant, ornamental for its spikes of blue, pink or white flowers. It may reach a meter in height. Since the aerial parts and seeds of ''C. ajacis'' have been found to contain diterpenoid alkaloids (see #Chemical constituents, chemical constituents below), including the highly toxic methyllycaconitineV. Venkateswarlu, S. K. Srivastava, B. S. Joshi, H. K. Desai and S. W. Pelletier (1995) ''J. Nat. Prod.'' 58 1527-1532., the plants should be considered as poisonous. Sowing In the UK, ''Consolida ajacis'' can be sowed under cover between February and April, or directly outdoors between April and May and/or late August and September.

Malva
''Malva'' is a genus of herbaceous annual, biennial, and perennial plants in the family Malvaceae. It is one of several closely related genera in the family to bear the common English name mallow. The genus is widespread throughout the temperate, subtropical and tropical regions of Africa, Asia and Europe. The leaves are alternate, palmately lobed. The flowers are from 0.5–5 cm diameter, with five pink, lilac, purple or white petals. Etymology The word "mallow" is derived from Old English "mealwe", which was imported from Latin "malva", cognate with Ancient Greek μαλάχη (malakhē) meaning "mallow", both perhaps reflecting a Mediterranean term. which has a purple colour; ultimately of Semitic origin. In 1859, the colour mauve was named after the French name for this plant. Uses Ornamental plant Several species are widely grown as garden flowers. Very easily grown, short-lived perennials are often grown as ornamental plants. Food Many species are edible as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Verbena
''Verbena'' (), also known as vervain or verveine, is a genus in the family Verbenaceae. It contains about 150 species of annual and perennial herbaceous or semi-woody flowering plants. The majority of the species are native to the Americas and Asia; however, '' Verbena officinalis'', the common vervain or common verbena, is the type species and native to Europe. Naming In English, the name ''Verbena'' is usually used in the United States and the United Kingdom; elsewhere, the terms ''verveine'' or ''vervain'' are in use. Description Verbena is a herbaceous flowering plant, belonging to the Verbenaceae family, and may be annual or perennial depending on the species. The leaves are usually opposite, simple, and in many species hairy, often densely so. The flowers are small, with five petals, and borne in dense spikes.

Oral Mite Anaphylaxis
Oral mite anaphylaxis (OMA), also known as pancake syndrome, is severe allergic reaction triggered by the ingestion of food contaminated with specific mites. The condition is associated with the consumption of wheat or maize flour that has been improperly stored in humid environments, leading to mite infestation. Symptoms can range from mild allergic reactions to severe anaphylaxis, often occurring shortly after ingestion of contaminated food. The disease name comes from reports of people becoming ill after eating pancakes made from contaminated wheat or corn (maize) flour. Signs and Symptoms Oral Mite Anaphylaxis (OMA) typically presents with acute allergic symptoms emerging within 10 to 240 minutes following the consumption of mite-contaminated flour. These symptoms affect multiple organ systems, often progressing rapidly. Respiratory manifestations are common and may include stridor, wheezing, sneezing, and nasal obstruction, which can worsen over time. Angioedema involving the ...

Mouse
A mouse (: mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (''Mus musculus''). Mice are also popular as pets. In some places, certain kinds of Apodemus, field mice are locally common. They are known to invade homes for food and shelter. Mice are typically distinguished from rats by their size. Generally, when a muroid rodent is discovered, its common name includes the term ''mouse'' if it is smaller, or ''rat'' if it is larger. The common terms ''rat'' and ''mouse'' are not Taxonomy (biology), taxonomically specific. Typical mice are classified in the genus ''Mus (genus), Mus'', but the term ''mouse'' is not confined to members of ''Mus'' and can also apply to species from other genera such as the deer mouse, deer mouse (''Peromyscus''). Fancy mouse, Domestic mice sold as pets often differ substantially in size f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honey
Honey is a sweet and viscous substance made by several species of bees, the best-known of which are honey bees. Honey is made and stored to nourish bee colonies. Bees produce honey by gathering and then refining the sugary secretions of plants (primarily floral nectar) or the secretions of other insects, like the honeydew of aphids. This refinement takes place both within individual bees, through regurgitation and enzymatic activity, and during storage in the hive, through water evaporation that concentrates the honey's sugars until it is thick and viscous. Honey bees stockpile honey in the hive. Within the hive is a structure made from wax called honeycomb. The honeycomb is made up of hundreds or thousands of hexagonal cells, into which the bees regurgitate honey for storage. Other honey-producing species of bee store the substance in different structures, such as the pots made of wax and resin used by the stingless bee. Honey for human consumption is collected ...

Cheese
Cheese is a type of dairy product produced in a range of flavors, textures, and forms by coagulation of the milk protein casein. It comprises proteins and fat from milk (usually the milk of cows, buffalo, goats or sheep). During production, milk is usually acidified and either the enzymes of rennet or bacterial enzymes with similar activity are added to cause the casein to coagulate. The solid curds are then separated from the liquid whey and pressed into finished cheese. Some cheeses have aromatic molds on the rind, the outer layer, or throughout. Over a thousand types of cheese exist, produced in various countries. Their styles, textures and flavors depend on the origin of the milk (including the animal's diet), whether they have been pasteurised, the butterfat content, the bacteria and mold, the processing, and how long they have been aged. Herbs, spices, or wood smoke may be used as flavoring agents. Other added ingredients may include black pepper, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
