Gilberto Righi

Gilberto Righi is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Gilberto Righi rather than just read about it. In short: Gilberto Righi (1937–1999) was an important earthworm taxonomist from São Paulo, Brazil, who helped define the magnitude of his country's diverse soil fauna. During more than 40 highly productive years as professor and researcher at the University of São Paulo, Righi published over 100 scientific papers, 85 of which treat earthworm taxonomy, 5 treat earthworm physiology, 5 treat earthworm ecology, and 3 treat earthw…

Key takeaways

Gilberto Righi belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Gilberto Righi to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Gilberto Righi from memory before moving on to harder problems.

Reference excerpt

Gilberto Righi (1937–1999) was an important earthworm taxonomist from São Paulo, Brazil, who helped define the magnitude of his country's diverse soil fauna. During more than 40 highly productive years as professor and researcher at the University of São Paulo, Righi published over 100 scientific papers, 85 of which treat earthworm taxonomy, 5 treat earthworm physiology, 5 treat earthworm ecology, and 3 treat earthworm biogeography. Besides these, he issued 16 papers on microdrile oligochaetes and 17 on other invertebrate groups, mainly on crustaceans and molluscs. Most of Righi's taxonomic work was on Brazilian earthworms, but he also studied species from other Neotropical countries, including Peruvian earthworms. Righi was the author of one new family, 25 new genera, and 224 new species of earthworms, mostly from Brazil (Fragoso, Brown & Feijoo, 2003). Righi's vast collection of earthworms, in over 1600 spirit containers, is deposited in the Oligochaeta collection of the Museu de Zoologia of the University of São Paulo (Moreno & Mischis, 2003). In addition, his Amazonian material can be found at both the Instituto Nacional de Pesquisas da Amazônia, in Manaus, and the Museu Paraense Emílio Goeldi, in Belém. A complete bibliography of Righi's publications on earthworms can be found in Mischis & Reynolds (1999). In the words of Dr. Mischis, Righi's student and co-worker: "Professor Gilberto Righi was a man of science who over and above his achievements in the scientific field was a teacher and most of all a man of goodness" (Moreno & Mischis, 2003).

Worked examples

Example 1 — a first encounter with Gilberto Righi

Start with the simplest possible case. Write down what Gilberto Righi 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 Gilberto Righi 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 Gilberto Righi 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 Gilberto Righi

In research: Gilberto Righi 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 Gilberto Righi 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: Gilberto Righi is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1937 births, 1999 deaths, 20th-century Brazilian zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Gilberto Righi 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.
