Reig's opossum

Reig's opossum 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 Reig's opossum rather than just read about it. In short: Reig's opossum (Monodelphis reigi) is a South American opossum species of the family Didelphidae, discovered in 2004. It is named after Argentine biologist Osvaldo Reig (1929–1992).

Key takeaways

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

Reference excerpt

Reig's opossum (Monodelphis reigi) is a South American opossum species of the family Didelphidae, discovered in 2004. It is named after Argentine biologist Osvaldo Reig (1929–1992). It was initially found in montane forest in Canaima National Park, Venezuela at an elevation of 1300 m in the Sierra de Lema. It is typically found between 1100 m and 2050 m on Mount Ayanganna.

Worked examples

Example 1 — a first encounter with Reig's opossum

Start with the simplest possible case. Write down what Reig's opossum 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 Reig's opossum 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 Reig's opossum 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 Reig's opossum

In research: Reig's opossum 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 Reig's opossum 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: Reig's opossum is common in secondary-school and first-year university syllabi. It links to neighbouring topics Endemic fauna of Venezuela, Guayana Highlands, IUCN Red List vulnerable species, so understanding it makes those chapters shorter.
In everyday life: Look for Reig's opossum 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.
