Roosmalen's dwarf porcupine

Roosmalen's dwarf porcupine 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 Roosmalen's dwarf porcupine rather than just read about it. In short: Roosmalen's dwarf porcupine (Coendou roosmalenorum) is a porcupine species from the New World porcupine family likely endemic to northern Brazil. Only three specimens were known at the time, and only one had a collection locality.

Key takeaways

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

Reference excerpt

Roosmalen's dwarf porcupine (Coendou roosmalenorum) is a porcupine species from the New World porcupine family likely endemic to northern Brazil. Only three specimens were known at the time, and only one had a collection locality. It is named for Marc van Roosmalen and his son Tomas, whose collections from the middle Madeira included the first known specimens. It was soon assigned to the genus Sphiggurus, although this genus was not recognized by the authors. Genetic studies in 2013 have since showed Sphiggurus to be polyphyletic (this taxon was omitted from the study). Nonetheless, it is commonly classified as Sphiggurus roosmalenorum. Coendou roosmalenorum may be misspelled due to a conflicting basionym combination.

Worked examples

Example 1 — a first encounter with Roosmalen's dwarf porcupine

Start with the simplest possible case. Write down what Roosmalen's dwarf porcupine 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 Roosmalen's dwarf porcupine 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 Roosmalen's dwarf porcupine 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 Roosmalen's dwarf porcupine

In research: Roosmalen's dwarf porcupine 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 Roosmalen's dwarf porcupine 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: Roosmalen's dwarf porcupine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Coendou, Endemic mammals of Brazil, IUCN Red List data deficient species, so understanding it makes those chapters shorter.
In everyday life: Look for Roosmalen's dwarf porcupine 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.
