Maria Tonelli-Rondelli
Maria Tonelli-Rondelli (1899 – 1970) was an Italian entomologist who studied the taxonomy and identification of ticks (Ixodidae), especially South American species. Early life and education She was born in Turin in 1899, the daughter of Alipio Rondelli and Maria Pia (Marina) Zanetti. She studied at University of Turin, graduating in natural sciences in 1921 and then geography in 1923. After graduating she worked at the university. She married the mathematician Leonida Tonelli in 1927. He died in 1946. Career She began her career by translating into Italian volumes of ''Zoology'' by Rémy Perrier. This was published with a preface by the Italian zoologist Umberto Pierantoni. However the focus of her career was on ticks. She examined specimens in the collections at Milan and Turin museums and specimens from scientific expeditions. In 1928 she described a new species, ''Ixodes nivalis'' from specimens obtained in the Gran Paradiso National Park in Italy. She worked especially ...

Turin
Turin ( , Piedmontese: ; it, Torino ) is a city and an important business and cultural centre in Northern Italy. It is the capital city of Piedmont and of the Metropolitan City of Turin, and was the first Italian capital from 1861 to 1865. The city is mainly on the western bank of the Po River, below its Susa Valley, and is surrounded by the western Alpine arch and Superga Hill. The population of the city proper is 847,287 (31 January 2022) while the population of the urban area is estimated by Eurostat to be 1.7 million inhabitants. The Turin metropolitan area is estimated by the OECD to have a population of 2.2 million. The city used to be a major European political centre. From 1563, it was the capital of the Duchy of Savoy, then of the Kingdom of Sardinia ruled by the House of Savoy, and the first capital of the Kingdom of Italy from 1861 to 1865. Turin is sometimes called "the cradle of Italian liberty" for having been the political and intellectual centre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Turin
The University of Turin ( Italian: ''Università degli Studi di Torino'', UNITO) is a public research university in the city of Turin, in the Piedmont region of Italy. It is one of the oldest universities in Europe and continues to play an important role in research and training. It is steadily ranked among the top 5 Italian universities and it is ranked third for research activities in Italy, according to the latest data by ANVUR. History Overview The University of Turin was founded as a ''studium'' in 1404, under the initiative of Prince Ludovico di Savoia. From 1427 to 1436 the seat of the university was transferred to Chieri and Savigliano. It was closed in 1536 and reestablished by Duke Emmanuel Philibert thirty years later. It started to gain its modern shape following the model of the University of Bologna, although significant development did not occur until the reforms made by Victor Amadeus II, who also created the Collegio delle Province for students not na ...

Rémy Perrier
Rémy Perrier (14 June 1861, Tulle – 27 June 1936, Chaunac) was a French zoologist. He was the younger brother of zoologist Edmond Perrier (1844-1921) who directed the French National Museum of Natural History from 1900 to 1919 and founded the Friends of the Natural History Museum society in 1907. Rémy Perrier studied natural sciences at the École normale supérieure, afterwards teaching classes in Poitiers. From 1926 to 1931 he was a professor of zoology at the faculty des sciences in Paris. He was a member of the ''Société des lettres, sciences et arts de la Corrèze''. Perrier specialized in research on the Prosobranchia (a subclass of snails). He is also remembered for his study of sea cucumbers, being credited with creation of the taxonomic genus '' Gastrothuria''. Publications Beginning in 1923, Perrier released "''La Faune de la France en tableaux synoptiques illustrés''", a work on zoology published in ten installments by Librairie Delagrave. * 1A.

Tick
Ticks (order Ixodida) are parasitic arachnids that are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, species, and "fullness". Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families, the Ixodidae or hard ticks, and the Argasidae, or soft ticks. '' Nuttalliella,'' a genus of tick from southern Africa is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalothorax and abdomen are completely fused. In ad ...

Gran Paradiso National Park
Gran Paradiso National Park (Italian: ''Parco nazionale del Gran Paradiso''; ), is an Italian national park in the Graian Alps, between the Aosta Valley and Piedmont regions. The park is named after Gran Paradiso mountain, which is located in the park; it is contiguous with the French Vanoise National Park. The land the park encompasses was initially protected in order to protect the Alpine ibex from poachers, as it was a personal hunting ground for King Victor Emmanuel II, but now also protects other species. History In the early 19th century, due to hunting, the Alpine ibex survived in the Gran Paradiso and Vanoise area. Approximately 60 individual ibex survived, here. Ibex were intensively hunted, partly for sport, but also because their body parts were thought to have therapeutic properties: talismans were made from a small cross-shaped bone near the ibex's heart in order to protect against violent death. Due to the alarming decrease in the ibex population, Victor Emmanuel, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amblyomma
''Amblyomma'' is a genus of hard ticks. Some are disease vectors, for example the Rocky Mountain spotted fever in Brazil or ehrlichiosis in the United States. This genus is the third largest in the family Ixodidae, with its species primarily occupying the torrid zones of all the continents. The centre of species diversity is on the American continent, where half of all the species occur. On this continent, ''Amblyomma'' species reach far beyond the torrid zone, up to the 40th parallel in the Northern Hemisphere, to the 50th parallel in the Southern Hemisphere, and even reaches the alpine zone of the Andes. They also occur in Eurasia, Africa and Australia. G. V.

Disease Vector
In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen to another living organism; agents regarded as vectors are organisms, such as parasites or microbes. The first major discovery of a disease vector came from Ronald Ross in 1897, who discovered the malaria pathogen when he dissected a mosquito. Arthropods Arthropods form a major group of pathogen vectors with mosquitoes, flies, sand flies, lice, fleas, ticks, and mites transmitting a huge number of pathogens. Many such vectors are haematophagous, which feed on blood at some or all stages of their lives. When the insects feed on blood, the pathogen enters the blood stream of the host. This can happen in different ways. The ''Anopheles'' mosquito, a vector for malaria, filariasis, and various arthropod-borne-viruses (arboviruses), inserts its delicate mouthpart under the skin and feeds on its host's blood. The parasites the mosquito carries are usually located in its salivary ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Ludwig Koch
Carl Ludwig Koch (21 September 1778 – 23 August 1857) was a German entomologist and arachnologist. He was responsible for classifying a great number of spiders, including the Brazilian whiteknee tarantula and common house spider. He was born in Kusel, Germany, and died in Nuremberg, Germany. Carl Ludwig Koch was an inspector of water and forests. His principal work ''Die Arachniden'' (1831–1848) (16 volumes) was commenced by Carl Wilhelm Hahn Carl Wilhelm Hahn (Lat. ''Carolus Guilielmus Hahn'', 16 December 1786 – 7 November 1835) was a German zoologist and author of the first German monograph on spiders. C. W. Hahn was an all-round natural scientist – not at all unusual for his t ... (1786–1836). Koch was responsible for the last 12 volumes. He also finished the chapter on spiders in ''Faunae insectorum germanicae initia oder Deutschlands Insecten'' lements of the insect fauna of Germanya work by Georg Wolfgang Franz Panzer (1755–1829). He also co-authored ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance ( shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Fr ...

Amblyomma Cajennense
''Amblyomma cajennense'' or Cayenne tick is a species of tick found in a range from the southern part of the United States to northern Argentina, through Central America and some of the Caribbean. As a consequence the species has adapted to a wide range of environmental conditions. There are also major geographic barriers such as large rivers and the Andes mountain range. There has been debate over whether ''A. cajennense'' is a single species or whether it is a complex of species. In the 1930s, Maria Tonelli-Rondelli proposed that the morphological variation within the species indicated that it was a complex, while in the 1950s this variation was proposed to be due to normal variation between individuals of one species. Molecular biological analyses have indicated that ''A. cajennense'' is a complex of species. A 2014 studySantiago Nava, Lorenza Beati, Marcelo B. Labruna, Abraham G. Cáceres, Atilio J.

Rocky Mountain Spotted Fever
Rocky Mountain spotted fever (RMSF) is a bacterial disease spread by ticks. It typically begins with a fever and headache, which is followed a few days later with the development of a rash. The rash is generally made up of small spots of bleeding and starts on the wrists and ankles. Other symptoms may include muscle pains and vomiting. Long-term complications following recovery may include hearing loss or loss of part of an arm or leg. The disease is caused by ''Rickettsia rickettsii'', a type of bacterium that is primarily spread to humans by American dog ticks, Rocky Mountain wood ticks, and brown dog ticks. Rarely the disease is spread by blood transfusions. Diagnosis in the early stages is difficult. A number of laboratory tests can confirm the diagnosis but treatment should be begun based on symptoms. It is within a group known as spotted fever rickettsiosis, together with ''Rickettsia parkeri'' rickettsiosis, Pacific Coast tick fever, and rickettsialpox. Treatment ...
