Reference excerpt

Raúl Adolfo Ringuelet Ph.D. (1914 – 1982) was an Argentine zoologist. Ringuelet published more than 100 scientific papers on the ecology, limnology, biogeography, and conservation of South American freshwaters, and was a mentor to a whole generation of Argentine biologists. Ringuelet's research interests were exceptionally broad, including numerous studies of leeches (Hirudinea), harvestmen spiders (Opiliones), crustaceans, chironomid flies and Neotropical fishes. The UNLP is named in his honor. Ringuelet was born in La Plata, September 10, 1914. He graduated in 1939 with a Doctor of Natural Sciences at the Institute of Museum, Universidad Nacional de La Plata (UNLP). Ringuelet published his first scientific work in 1936. Ringuelet went on to publish 17 works of Arachnology, with one relating to the Order Scorpiones and the others to the Order Opiliones, 44 papers on the Hirudinea leeches, 24 on various crustaceans, and 14 specifically on Biogeography. Ringuelet held several professorships at the Universidad Nacional de La Plata: Adjunct professor of general Zoology (1944–1948), Acting Professor (1946–1947) and Head (1947–1955) Invertebrate Zoology, Professor Acting Zoogeography (1958), Vertebrate Zoology Professor (1957–1966), Professor of Ecology and Zoogeography (1960, per vitam in 1972) and Professor of Limnology (1969–1978). He was also Professor of Systematic Zoology in the Faculty of Natural Sciences, University of Buenos Aires (1956–1964). In recognition of his career, the National University of La Plata was appointed Extraordinary Professor Emeritus degree (1980). From 1978 until his death Ringuelet was a Senior Researcher at the National Research Council (CONICET).

Worked examples

Example 1 — a first encounter with Raúl Adolfo Ringuelet

Start with the simplest possible case. Write down what Raúl Adolfo Ringuelet claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Raúl Adolfo Ringuelet before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Raúl Adolfo Ringuelet ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Raúl Adolfo Ringuelet

In research: Raúl Adolfo Ringuelet appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Raúl Adolfo Ringuelet in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Raúl Adolfo Ringuelet is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1914 births, 1982 deaths, 20th-century Argentine zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Raúl Adolfo Ringuelet outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
