Gabriel Bibron
Gabriel Bibron (20 October 1805 – 27 March 1848) was a French zoologist and herpetologist. He was born in Paris. The son of an employee of the Museum national d'histoire naturelle, he had a good foundation in natural history and was hired to collect vertebrates in Italy and Sicily. Under the direction of Jean Baptiste Bory de Saint-Vincent (1778–1846), he took part in the Morea expedition to Peloponnese. He classified numerous reptile species with André Marie Constant Duméril (1774–1860), whom he had met in 1832. Duméril was interested mainly in the relations between genera, and he left to Bibron the task of describing the species. Working together they produced the ''Erpétologie Générale'', a comprehensive account of the reptiles, published in ten volumes from 1834 to 1854. Also, Bibron assisted Duméril with teaching duties at the museum and was an instructor at a primary school in Paris. Bibron contracted tuberculosis and retired in 1845 to Saint-A ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chondrodactylus Bibronii
''Chondrodactylus bibronii'', commonly known as Bibron's thick-toed gecko, Bibron's sand gecko, or simply Bibron's gecko, is a species of lizard in the family Gekkonidae. The species is native to southern Africa. ''C. bibronii'' has been used as an animal model in bioastronautic research examining the effects of spaceflight on the morphology and physiology of vertebrates.Gulimova VI et al. (2006"Effect of 16-Day Spaceflight on the Morphology of Thick-Toed Geckos (''Pachydactylus bibronii'' Smith, 1846)" ''Journal of Gravitational Physiology'' 13 (1): 197-200.

Boidae
The Boidae, commonly known as boas or boids, are a family of nonvenomous snakes primarily found in the Americas, as well as Africa, Europe, Asia, and some Pacific Islands. Boas include some of the world's largest snakes, with the green anaconda of South America being the heaviest and second-longest snake known; in general, adults are medium to large in size, with females usually larger than the males. Five subfamilies, comprising 12 genera and 49 species, are currently recognized. The Old Tupi name for such snakes was mbói, which figures in the etymology of names such as ''jibóia'' and ''boitatá'' (the Brazilian name for the mythical giant anaconda). Description Like the pythons, boas have elongated supratemporal bones. The quadrate bones are also elongated, but not as much, while both are capable of moving freely so when they swing sideways to their maximum extent, the distance between the hinges of the lower jaw is greatly increased.Parker HW, Grandison AGC. 1977.

Venomous Snake
Venomous snakes are Species (biology), species of the Suborder (biology), suborder Snake, Serpentes that are capable of producing Snake venom, venom, which they use for killing prey, for defense, and to assist with digestion of their prey. The venom is typically delivered by injection using hollow or grooved fangs, although some venomous snakes lack well-developed fangs. Common venomous snakes include the Family (biology), families Elapidae, Viperidae, Atractaspididae, and some of the Colubridae. The toxicity of venom is mainly indicated by murine , while multiple factors are considered to judge the potential danger to humans. Other important factors for risk assessment include the likelihood that a snake will bite, the quantity of venom delivered with the bite, the efficiency of the delivery mechanism, and the location of a bite on the body of the victim. Snake venom may have both neurotoxic and hemotoxic properties. There are about 600 venomous snake species in the world. Evolu ...

Scolecophidia
The Scolecophidia, commonly known as blind snakes or thread snakes, are an infraorder of snakes. They range in length from . All are fossorial (adapted for burrowing). Five families and 39 genera are recognized. The Scolecophidia infraorder is most likely paraphyletic. Taxonomy The infraorder name Scolecophidia derives from the two Ancient Greek words or σκώληκος (, genitive ), meaning "earthworm", and (), meaning "snake". It refers to their shape and fossorial lifestyle. Families Evolution Despite only having fossils as early as the Cretaceous, Scolecophidia itself likely originated in the Middle Jurassic, with Anomalepididae, Leptotyphlopidae, and Typhlopoidea diverging from one another during the Late Jurassic. Within Typhlopoidea, Gerrhopilidae likely diverged from the Xenotyphlopidae-Typhlopidae clade during the Early Cretaceous, and Xenotyphlopidae and Typhlopidae likely diverged from one another during the Late Cretaceous.

Tuberculosis
Tuberculosis (TB) is an infectious disease usually caused by '' Mycobacterium tuberculosis'' (MTB) bacteria. Tuberculosis generally affects the lungs, but it can also affect other parts of the body. Most infections show no symptoms, in which case it is known as latent tuberculosis. Around 10% of latent infections progress to active disease which, if left untreated, kill about half of those affected. Typical symptoms of active TB are chronic cough with blood-containing mucus, fever, night sweats, and weight loss. It was historically referred to as consumption due to the weight loss associated with the disease. Infection of other organs can cause a wide range of symptoms. Tuberculosis is spread from one person to the next through the air when people who have active TB in their lungs cough, spit, speak, or sneeze. People with Latent TB do not spread the disease. Active infection occurs more often in people with HIV/AIDS and in those who smoke. Diagnosis of active TB is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karl Patterson Schmidt
Karl Patterson Schmidt (June 19, 1890 – September 26, 1957) was an American herpetologist. Family Schmidt was the son of George W. Schmidt and Margaret Patterson Schmidt. George W. Schmidt was a German professor, who, at the time of Karl Schmidt's birth, was teaching in Lake Forest, Illinois. His family left the city in 1907 and settled in Wisconsin. They worked on a farm near Stanley, Wisconsin, where his mother and his younger brother died in a fire on August 7, 1935. The brother, Franklin J. W. Schmidt, had been prominent in the then-new field of wildlife management. Karl Schmidt married Margaret Wightman in 1919, and they had two sons, John and Robert. Education In 1913, Schmidt entered Cornell University to study biology and geology. In 1915, he discovered his preference for herpetology during a four-month training course at the Perdee Oil Company in Louisiana. In 1916, he received the degree of Bachelor of Arts and made his first geological expedition to Santo Do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
