Jacques Pucheran

Jacques Pucheran is a science 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 Jacques Pucheran rather than just read about it. In short: Jacques Pucheran (2 June 1817 – 13 January 1895) was a French zoologist born in Clairac. He was a grandnephew to physiologist Étienne Serres (1786-1868).

Key takeaways

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

Reference excerpt

Jacques Pucheran (2 June 1817 – 13 January 1895) was a French zoologist born in Clairac. He was a grandnephew to physiologist Étienne Serres (1786-1868). Pucheran accompanied the expedition on the Astrolabe between 1837 and 1840, under the command of Jules Dumont d'Urville, with fellow-naturalists Jacques Bernard Hombron and Honoré Jacquinot. On his return he contributed the ornithological section (with Jacquinot) of "Voyage au Pôle sud et dans l'Océanie sur les corvettes L'Astrolabe et La Zélée" (1841–1854). Pucheran worked as a zoologist and naturalist at the Muséum national d'histoire naturelle. He was the author of many works in the fields of ornithology, mammalogy, anthropology, etc. With Florent Prévost and Isidore Geoffroy Saint-Hilaire, he published a catalog involving species of mammals and birds kept in the collections at the museum, titled "Muséum d'histoire naturelle de Paris. Catalogue méthodique," etc. (1851). He was a member of the Société d'Agen académique, and a chevalier in the Légion d'honneur and the Ordre de la Conception de Portugal. He classified numerous zoological taxa, and the following are a few ornithological species that are named after him.

Black-cheeked woodpecker, Melanerpes pucherani (Malherbe 1849) Crested guineafowl, Guttera pucherani (Hartlaub 1861) Red-billed ground-cuckoo, Neomorphus pucheranii (Deville 1851).

Worked examples

Example 1 — a first encounter with Jacques Pucheran

Start with the simplest possible case. Write down what Jacques Pucheran claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Jacques Pucheran 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 Jacques Pucheran 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 Jacques Pucheran

In research: Jacques Pucheran appears in science 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 Jacques Pucheran 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: Jacques Pucheran is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1817 births, 1894 deaths, French ornithologists, so understanding it makes those chapters shorter.
In everyday life: Look for Jacques Pucheran 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.
