Vieira's titi monkey

Vieira's titi monkey 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 Vieira's titi monkey rather than just read about it. In short: Vieira's titi monkey (Plecturocebus vieirai) is a species of titi, a type of New World monkey, from central-northern Brazil. Taxonomy Vieira's titi belongs to the New World monkey family Pitheciidae, which contains the titis (Callicebus), saki monkeys (Pithecia), bearded sakis (Chiropotes), and uakaris (Cacajao).

Key takeaways

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

Reference excerpt

Vieira's titi monkey (Plecturocebus vieirai) is a species of titi, a type of New World monkey, from central-northern Brazil.

Taxonomy Vieira's titi belongs to the New World monkey family Pitheciidae, which contains the titis (Callicebus), saki monkeys (Pithecia), bearded sakis (Chiropotes), and uakaris (Cacajao).

Worked examples

Example 1 — a first encounter with Vieira's titi monkey

Start with the simplest possible case. Write down what Vieira's titi monkey 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 Vieira's titi monkey 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 Vieira's titi monkey 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 Vieira's titi monkey

In research: Vieira's titi monkey 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 Vieira's titi monkey 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: Vieira's titi monkey is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arboreal mammals, Endemic mammals of Brazil, IUCN Red List critically endangered species, so understanding it makes those chapters shorter.
In everyday life: Look for Vieira's titi monkey 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.
