Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné 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". 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 the 1750s and 1760s, he continued to collect an ...

Entomophily
Entomophily or insect pollination is a form of pollination whereby pollen of plants, especially but not only of flowering plants, is distributed by insects. Flowers pollinated by insects typically advertise themselves with bright colours, sometimes with conspicuous patterns (honey guides) leading to rewards of pollen and nectar; they may also have an attractive scent which in some cases mimics insect pheromones. Insect pollinators such as bees have adaptations for their role, such as lapping or sucking mouthparts to take in nectar, and in some species also pollen baskets on their hind legs. This required the coevolution of insects and flowering plants in the development of pollination behaviour by the insects and pollination mechanisms by the flowers, benefiting both groups. Coevolution History The early spermatophytes (seed plants) were largely dependent on the wind to carry their pollen from one plant to another. Prior to the appearance of flowering plants some gymnospe ...

Herbalism
Herbal medicine (also herbalism) is the study of pharmacognosy and the use of medicinal plants, which are a basis of traditional medicine. With worldwide research into pharmacology, some herbal medicines have been translated into modern remedies, such as the anti-malarial group of drugs called artemisinin isolated from '' Artemisia annua'', a herb that was known in Chinese medicine to treat fever. There is limited scientific evidence for the safety and efficacy of plants used in 21st century herbalism, which generally does not provide standards for purity or dosage. The scope of herbal medicine commonly includes fungal and bee products, as well as minerals, shells and certain animal parts. Herbal medicine is also called phytomedicine or phytotherapy. Paraherbalism describes alternative and pseudoscientific practices of using unrefined plant or animal extracts as unproven medicines or health-promoting agents. Paraherbalism relies on the belief that preserving various ...

Butts And Bounds
Butts and bounds, shortened form for "abuttals and boundaries" of a property, are the boundary lines delineated between plots of land, usually those which define the end of an estate, as used in legal deeds, titles, etc. These are usually descriptive features in the property, such as trees, outcroppings of stone, or riverine brooks, etc., and are signified in the legal deed for purposes of identification. Historical uses The practice of signifying butts and bounds in the sale of real estate and in legal deeds and contracts is an ancient practice, having attestation in the Hebrew Bible. In the episode of Abraham who purchased the field of Ephron in , and where it describes the cave and the trees in the outermost bounds of the property, the Sages of Israel learnt thereby that he that sells his field must write in the deed its landmarks and boundaries. According to rabbinic tradition, Joshua, when dividing the Land of Canaan among the twelve tribes of Israel, planted Sea squill ( ...

Fellah
A fellah ( ar, فَلَّاح ; feminine ; plural ''fellaheen'' or ''fellahin'', , ) is a peasant, usually a farmer or agricultural laborer in the Middle East and North Africa. The word derives from the Arabic word for "ploughman" or "tiller". Due to a continuity in beliefs and lifestyle with that of the Ancient Egyptians, the fellahin of Egypt have been described as the "true Egyptians". A fellah could be seen wearing a simple Egyptian cotton robe called ''galabieh'' (''jellabiya''). The word ''galabieh'' originated around 1715–25 and derived from the Egyptian slang word ''gallabīyah''. Origins and usage "Fellahin," throughout the Middle East in the Islamic periods referred to native villagers and farmers. It is translated as "peasants" or " farmers". Fellahin were distinguished from the ''effendi'' (land-owning class), although the fellahin in this region might be tenant farmers, smallholders, or live in a village that owned the land communally. Others applied the ...

Palestine (region)
Palestine ( el, Παλαιστίνη, ; la, Palaestina; ar, فلسطين, , , ; he, פלשתינה, ) is a geographic region in Western Asia. It is usually considered to include Israel and the State of Palestine (i.e. West Bank and Gaza Strip), though some definitions also include part of northwestern Jordan. The first written records to attest the name of the region were those of the Twentieth dynasty of Egypt, which used the term "Peleset" in reference to the neighboring people or land. In the 8th century, Assyrian inscriptions refer to the region of "Palashtu" or "Pilistu". In the Hellenistic period, these names were carried over into Greek, appearing in the Histories of Herodotus in the more recognizable form of "Palaistine". The Roman Empire initially used other terms for the region, such as Judaea, but renamed the region Syria Palaestina after the Bar Kokhba revolt. During the Byzantine period, the region was split into the provinces of Palaestina Prima, Palaestin ...

Bufadienolide
Bufadienolide is a chemical compound with steroid structure. Its derivatives are collectively known as bufadienolides, including many in the form of bufadienolide glycosides (bufadienolides that contain structural groups derived from sugars). These are a type of cardiac glycoside, the other being the cardenolide glycosides. Both bufadienolides and their glycosides are toxic; specifically, they can cause an atrioventricular block, bradycardia (slow heartbeat), ventricular tachycardia (a type of rapid heartbeat), and possibly lethal cardiac arrest. Etymology The term derives from the toad genus ''Bufo'' that contains bufadienolide glycosides, the suffix ''-adien-'' that refers to the two double bonds in the lactone ring, and the ending ''-olide'' that denotes the lactone structure. Consequently, related structures with only one double bond are called ''bufenolides'', and the saturated equivalent is ''bufanolide''. Classification According to MeSH, bufadienolides and bufanolides ...

Cardiac Glycoside
Cardiac glycosides are a class of organic compounds that increase the output force of the heart and decrease its rate of contractions by inhibiting the cellular sodium-potassium ATPase pump. Their beneficial medical uses are as treatments for congestive heart failure and cardiac arrhythmias; however, their relative toxicity prevents them from being widely used. Most commonly found as secondary metabolites in several plants such as foxglove plants, these compounds nevertheless have a diverse range of biochemical effects regarding cardiac cell function and have also been suggested for use in cancer treatment. Classification General structure The general structure of a cardiac glycoside consists of a steroid molecule attached to a sugar (glycoside) and an R group. The steroid nucleus consists of four fused rings to which other functional groups such as methyl, hydroxyl, and aldehyde groups can be attached to influence the overall molecule's biological activity. Cardiac glycosi ...

Polistes Gallicus
''Polistes gallicus'' is a species of paper wasp found in various parts of Europe, excluding England, Denmark, and Scandinavia, from warmer climates to cooler regions north of the Alps. Nests of these social insects are created in these various conditions. The ''Polistes'' species use an oral secretion to construct their nests, which consist of a combination of saliva and chewed plant fibers. This structural mixture physically protects the nest from various harsh elements and from weathering over time. Description and identification ''P. gallicus'', like other members of the subgenus ''Polistes (Polistes)'', has recognizable, bright yellow and black markings. They have smaller bodies than many of its allies that overlap in range, and their bodies are largely hairless. The species may be separated from allies through the following traits. Females are identified by having 12 antennal segments and 6 abdominal segments. The antennae are orange and paler on the ventral surface than i ...

Paper Wasp
Paper wasps are Vespidae, vespid wasps that gather fibers from dead wood and plant stems, which they mix with saliva, and use to construct nests made of gray or brown papery material. Some types of paper wasps are also sometimes called umbrella wasps, due to the distinctive design of their nests."Paper Wasp"
Microsoft Encarta Online Encyclopedia 2006.


Species

The name "paper wasps" typically refers to members of the Vespidae, vespid subfamily Polistinae, though it often colloquially includes members of the subfamilies Vespinae (hornets and yellowjackets) and Stenogastrinae, which also make nests out of paper. Twenty-two species of ''Polistes'' paper wasps have been identified in North America and approximately 300 species have been identified worldwide. The most common ...
