Thick-spined porcupine

Thick-spined 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 Thick-spined porcupine rather than just read about it. In short: The thick-spined porcupine (Hystrix crassispinis) is a species of rodent in the family Hystricidae. It is endemic to the island of Borneo and found in Brunei, Indonesia, and Malaysia.

Key takeaways

Thick-spined 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 Thick-spined porcupine to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Thick-spined porcupine from memory before moving on to harder problems.

Reference excerpt

The thick-spined porcupine (Hystrix crassispinis) is a species of rodent in the family Hystricidae. It is endemic to the island of Borneo and found in Brunei, Indonesia, and Malaysia.

History In 1996, the species was considered Near Threatened, but in 2008, this was lowered to Least Concern.

Distribution It is found in a wide variety of habitats ranging from natural forest to agricultural areas, with an elevation distribution of sea level to at least 1,200 m (3,900 ft).

Threats Although this porcupine is hunted for food, it is not a concern due to its wide distribution and high tolerance for habitat changes.

Worked examples

Example 1 — a first encounter with Thick-spined porcupine

Start with the simplest possible case. Write down what Thick-spined 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 Thick-spined 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 Thick-spined 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 Thick-spined porcupine

In research: Thick-spined 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 Thick-spined 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: Thick-spined porcupine is common in secondary-school and first-year university syllabi. It links to neighbouring topics Endemic fauna of Borneo, Hystrix (mammal), IUCN Red List least concern species, so understanding it makes those chapters shorter.
In everyday life: Look for Thick-spined 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.
