Réunion sheldgoose

Réunion sheldgoose 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 Réunion sheldgoose rather than just read about it. In short: The Réunion sheldgoose or Kervazo's Egyptian goose (Alopochen kervazoi) is an extinct species of sheldgoose from Réunion. It was a close relative of the Egyptian goose and was about the same size.

Key takeaways

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

Reference excerpt

The Réunion sheldgoose or Kervazo's Egyptian goose (Alopochen kervazoi) is an extinct species of sheldgoose from Réunion. It was a close relative of the Egyptian goose and was about the same size. There is only one description remaining, that of Dubois made in 1674. Apart from that, the species is only known from brief reports and subfossil bones, collected by British ornithologist Graham S. Cowles. Dubois' full account reads as follows:

Wild geese, slightly smaller than the European geese. They have the same feathering, but with the bill and feet red. They are very good [to eat].

Extinction Waterfowl on Réunion were overhunted. As early as 1667, François Martin complained of unsustainable hunting. The last record of the species is a 1709 listing of de la Merveille who stated that ducks and geese occurred "in quantity", but as Jean Feuilley had not listed waterfowl in his 1705 catalogue of Réunion's animals, de la Merveille's record is obviously based on obsolete hearsay information. Thus, the last record of the species appears to be the report of Père Bernardin in 1687. The species probably became extinct during the 1690s.

Worked examples

Example 1 — a first encounter with Réunion sheldgoose

Start with the simplest possible case. Write down what Réunion sheldgoose 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 Réunion sheldgoose 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 Réunion sheldgoose 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 Réunion sheldgoose

In research: Réunion sheldgoose 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 Réunion sheldgoose 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: Réunion sheldgoose is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alopochen, Anseriformes stubs, Bird extinctions since 1500, so understanding it makes those chapters shorter.
In everyday life: Look for Réunion sheldgoose 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.
