Pristidactylus valeriae

Pristidactylus valeriae 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 Pristidactylus valeriae rather than just read about it. In short: Pristidactylus valeriae is a species of lizard in the family Leiosauridae. The species is endemic to Chile where it is found in the Chilean matorral.

Key takeaways

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

Reference excerpt

Pristidactylus valeriae is a species of lizard in the family Leiosauridae. The species is endemic to Chile where it is found in the Chilean matorral.

Etymology The specific name, valeriae, is in honor of Donoso-Barros' fourth daughter, Valeria.

Habitat The preferred natural habitats of P. vaeriae are forest and shrubland at altitudes of 170–2,280 m (560–7,480 ft).

Reproduction P. valeriae is oviparous.

Worked examples

Example 1 — a first encounter with Pristidactylus valeriae

Start with the simplest possible case. Write down what Pristidactylus valeriae 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 Pristidactylus valeriae 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 Pristidactylus valeriae 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 Pristidactylus valeriae

In research: Pristidactylus valeriae 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 Pristidactylus valeriae 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: Pristidactylus valeriae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Endemic reptiles of Chile, Fauna of the Chilean Matorral, IUCN Red List endangered species, so understanding it makes those chapters shorter.
In everyday life: Look for Pristidactylus valeriae 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.
