Pokeweed
''Phytolacca americana'', also known as American pokeweed, pokeweed, poke sallet, dragonberries, and inkberry, is a poisonous, herbaceous perennial plant in the pokeweed family Phytolaccaceae. This pokeweed grows . It has simple leaves on green to red or purplish stems and a large white taproot. The flowers are green to white, followed by berries which ripen through red to purple to almost black which are a food source for songbirds such as gray catbird, northern mockingbird, northern cardinal, and brown thrasher, as well as other birds and some small non-avian animals (i.e., for species that are unaffected by its mammalian toxins). Pokeweed is native to eastern North America, the Midwest, and the South, with more scattered populations in the far West. It is also naturalized in parts of Europe and Asia. It is considered a pest species by farmers. Pokeweed is poisonous to humans, dogs, and livestock. In spring and early summer, shoots and leaves (not the root) are edible with pr ...

Pokeweed Mitogen
Pokeweed mitogen is a mitogen derived from the roots of ''Phytolacca americana''. It functions as a lectin and a mitotic stimulus for the division of lymphocytes. Biological Functions This lectin specifically induces the proliferation of B cells, plasma cells and T cells. This lectin contains Toll-like receptor 4 (TLR4) proteins which signals for the B-cell for a proliferative response. B cells are shown to have no response to pure PWM without the Toll-like receptor suggesting that PWM inducing ability relies on TLR4 protein's presence for the signaling of B-cells and the response. Research PWM can contribute to B-cell assay or other lymphocytes for testing. The amplified number of proliferated cells makes it easier to test different lymphocyte functions, biological mechanisms, and response to different stimuli. Pokeweed mitogen is also used in research studies to stimulate different lymphocytes and observe change. When looking at deficiency of CD26 in knockout mice, afte ...

List Of Poisonous Plants
Plants that produce toxins are referred to as poisonous plants. Plants that cause irritation on contact are also described as "poisonous". The toxins in poisonous plants affect herbivores, and deter them from consuming the plants. Plants cannot move to escape their predators, so they must have other means of protecting themselves from herbivorous animals. Some plants have physical defenses such as thorns, spines and prickles, but by far the most common type of protection is chemical. Over millennia, through the process of natural selection, plants have evolution of plants, evolved the means to produce a vast and complicated array of chemical compounds to deter herbivores. Tannin, for example, is a defensive compound that emerged relatively early in the evolutionary history of plants, while more complex molecules such as polyyne, polyacetylenes are found in younger groups of plants such as the Asterales. Many of the known Plant defense against herbivory, plant defense compounds pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berries
A berry is a small, pulpy, and often edible fruit. Typically, berries are juicy, rounded, brightly colored, sweet, sour or tart, and do not have a stone or pit, although many pips or seeds may be present. Common examples are strawberries, raspberries, blueberries, blackberries, red currants, white currants and blackcurrants. In Britain, soft fruit is a horticultural term for such fruits. In common usage, the term "berry" differs from the scientific or botanical definition of a fruit produced from the ovary of a single flower in which the outer layer of the ovary wall develops into an edible fleshy portion (pericarp). The botanical definition includes many fruits that are not commonly known or referred to as berries, such as grapes, tomatoes, cucumbers, eggplants, bananas, and chili peppers. Fruits commonly considered berries but excluded by the botanical definition include strawberries, raspberries, and blackberries, which are aggregate fruits and mulberries, which ...

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his Nobility#Ennoblement, ennoblement in 1761 as Carl von Linné#Blunt, Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In ...

Algonquin Peoples
The Algonquin people are an Indigenous people who now live in Eastern Canada. They speak the Algonquin language, which is part of the Algonquian language family. Culturally and linguistically, they are closely related to the Odawa, Potawatomi, Ojibwe (including Oji-Cree), Mississauga and Nipissing, with whom they form the larger Anicinàpe (Anishinaabeg). Algonquins call themselves Omàmiwinini (plural: Omàmiwininiwak) or the more generalised name of Anicinàpe. Though known by several names in the past, such as ''Algoumequin'', the most common term "Algonquin" has been suggested to derive from the Maliseet word (): "they are our relatives/allies." The much larger heterogeneous group of Algonquian-speaking peoples, who, according to Brian Conwell, stretch from Virginia to the Rocky Mountains and north to Hudson Bay, was named after the tribe. Most Algonquins live in Quebec. The nine recognized status Algonquin bands in that province and one in Ontario have a combin ...

Fencerow
In agriculture, fences are used to keep animals in or out of an area. They can be made from a wide variety of materials, depending on terrain, location and animals to be confined. Most agricultural fencing averages about high, and in some places, the height and construction of fences designed to hold livestock is mandated by law. A is the strip of land by a fence that is left uncultivated. It may be a hedgerow or a shelterbelt (windbreak) or a refugee for native plants. If not too narrow, it acts as a habitat corridor. History Historically throughout most of the world, domesticated livestock would roam freely and were fenced out of areas, such as gardens or fields of crops, where they were unwanted. Over time, especially where crop agriculture became dominant and population density of both humans and animals was significant, livestock owners were made to fence their animals in. The earliest fences were made of available materials, usually stone or wood, and these materials ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Edge Habitat
In ecology, edge effects are changes in population or community structures that occur at the boundary of two or more habitats. Areas with small habitat fragments exhibit especially pronounced edge effects that may extend throughout the range. As the edge effects increase, the boundary habitat allows for greater biodiversity. Urbanization is causing humans to continuously fragment landscapes and thus increase the edge effect. This change in landscape ecology is proving to have consequences. Generalist species, especially invasive ones, have been seen to benefit from this landscape change whilst specialist species are suffering. For example, the alpha diversity of edge-intolerant birds in Lacandona rainforest, Mexico, is decreasing as edge effects increase. Types * Inherent – Natural features stabilize the border location. * Induced – Transient natural disturbances (e.g., fire or flood) or human related activities, subject borders to successional changes over ...

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to ...

Pasture
Pasture (from the Latin ''pastus'', past participle of ''pascere'', "to feed") is land used for grazing. Pasture lands in the narrow sense are enclosed tracts of farmland, grazed by domesticated livestock, such as horses, cattle, sheep, or swine. The vegetation of tended pasture, forage, consists mainly of grasses, with an interspersion of legumes and other forbs (non-grass herbaceous plants). Pasture is typically grazed throughout the summer, in contrast to meadow which is ungrazed or used for grazing only after being mown to make hay for animal fodder. Pasture in a wider sense additionally includes rangelands, other unenclosed pastoral systems, and land types used by wild animals for grazing or browsing. Pasture lands in the narrow sense are distinguished from rangelands by being managed through more intensive agricultural practices of seeding, irrigation, and the use of fertilizers, while rangelands grow primarily native vegetation, managed with extensive pract ...

Biomedical Research
Medical research (or biomedical research), also known as experimental medicine, encompasses a wide array of research, extending from " basic research" (also called ''bench science'' or ''bench research''), – involving fundamental scientific principles that may apply to a ''preclinical'' understanding – to clinical research, which involves studies of people who may be subjects in clinical trials. Within this spectrum is applied research, or translational research, conducted to expand knowledge in the field of medicine. Both clinical and preclinical research phases exist in the pharmaceutical industry's drug development pipelines, where the clinical phase is denoted by the term ''clinical trial''. However, only part of the clinical or preclinical research is oriented towards a specific pharmaceutical purpose. The need for fundamental and mechanism-based understanding, diagnostics, medical devices, and non-pharmaceutical therapies means that pharmaceutical research ...
