Cornelis Gijsbert Gerrit Jan Van Steenis
Cornelis Gijsbert Gerrit Jan van Steenis (31 October 1901 – 14 May 1986) was a Dutch botanist. Van Steenis wrote many publications on the flora of the Maritime Southeast Asia region, among others about taxonomy and plant geography. Besides his expeditions in the Malay region, he also traveled in Australia and New Zealand. Biography Van Steenis attended high school in Utrecht from 1915 to 1920. He obtained his masters and PhD at the University of Utrecht in 1925 and 1927, respectively. From 1927 to 1946, Van Steenis was botanist at the herbarium of 's Lands Plantentuin at Buitenzorg (now Bogor). From 1935 to 1942, he was co-editor of ''De Tropische Natuur'', the magazine of the Dutch East Indian Natural History Society. From 1946 to 1949 he was active in the Netherlands. In 1948 and 1950, he took up Heinrich Zollinger's 1857 recognition of Malesia as a floristic region in the Paleotropical kingdom, and expanded it. Van Steenis suggested and then organized '' Flora Males ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central Range Montane Rain Forests
The Central Range montane rain forests is a tropical moist forest ecoregion on the island of New Guinea. The ecoregion covers the Central Range of the New Guinea Highlands, which extends along the spine of the island. The montane rain forests of the ecoregion are distinct from the surrounding lowland forests, and are home to many endemic plants and animals. Geography The ecoregion includes the montane rain forests of the Central Range, or Central Cordillera, between 1000 and 3000 metres elevation. The Central Range extends east and west across New Guinea, with the western portion of the range in Indonesia and the eastern portion in Papua New Guinea. The Central Range includes the Weyland Mountains at its western end, the Snow Mountains in Indonesia's Papua Province, the Star Mountains which span the Indonesia–Papua New Guinea border, and the Central and Eastern Highlands of Papua New Guinea. The Bird's Neck Isthmus is at the western end of the Central Range. The isthmus' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1972
Plants are the eukaryotes that form the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts, mosses, lycophytes, ferns, conifers and other gymnosperm ...

Flora Of The Central Range Montane Rain Forests
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) was ...

Endemic Flora Of Papua New Guinea
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Hypoglycemic Shock
Hypoglycemia (American English), also spelled hypoglycaemia or hypoglycæmia (British English), sometimes called low blood sugar, is a fall in blood sugar to levels below normal, typically below 70 mg/dL (3.9 mmol/L). Whipple's triad is used to properly identify hypoglycemic episodes. It is defined as blood glucose below 70 mg/dL (3.9 mmol/L), symptoms associated with hypoglycemia, and resolution of symptoms when blood sugar returns to normal. Hypoglycemia may result in headache, tiredness, clumsiness, trouble talking, confusion, fast heart rate, sweating, shakiness, nervousness, hunger, loss of consciousness, seizures, or death. Symptoms typically come on quickly. Symptoms can remain even soon after raised blood level. The most common cause of hypoglycemia is medications used to treat diabetes such as insulin, sulfonylureas, and biguanides. Risk is greater in diabetics who have eaten less than usual, recently exercised, or consumed alcohol. Other causes o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants Of The World Online
Plants of the World Online (POWO) is an online taxonomic database published by the Royal Botanic Gardens, Kew. History Following the Convention on Biological Diversity, the Royal Botanic Gardens in Kew launched Plants of the World Online in March 2017 with the goal of creating an exhaustive online database of all seed-bearing plants worldwide. (Govaerts wrongly speaks of "Convention for Botanical Diversity (CBD)). The initial focus was on tropical African flora, particularly flora ''Zambesiaca'', flora of West and East Tropical Africa. Since March 2024, the website has displayed AI-generated predictions of the extinction risk for each plant. Description The database uses the same taxonomical source as the International Plant Names Index, which is the World Checklist of Vascular Plants (WCVP). The database contains information on the world's flora gathered from 250 years of botanical research. It aims to make available data from projects that no longer have an online ...

Tauri River
The Tauri (; in Ancient Greek), or Taurians, also Scythotauri, Tauri Scythae, Tauroscythae ( Pliny, ''H. N.'' 4.85) were an ancient people settled on the southern coast of the Crimea peninsula, inhabiting the Crimean Mountains in the 1st millennium BC and the narrow strip of land between the mountains and the Black Sea. According to the sources, the Tauri were the first inhabitants of the Crimean peninsula and never abandoned its borders. They gave their name to the peninsula, which was known in ancient times as ''Taurica'', ''Taurida'' and ''Tauris''. Assimilation Taurians intermixed with the Scythians starting from the end of 3rd century BC, and were mentioned as Tauroscythians and Scythotaurians in the works of ancient Greek writers. The Taurians underwent the rule of the Bosporan Kingdom from the 5th century BC. As a result of Roman occupations, Taurians were romanized in the first century AD. Later the Taurians were subsumed by the Alans and Goths, and existed till the 4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
