Lucifer titi monkey

Lucifer 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 Lucifer titi monkey rather than just read about it. In short: The Lucifer titi monkey (Cheracebus lucifer) is a species of titi, a type of New World monkey, from South America. It is found in Brazil, Colombia, Ecuador, and Peru.

Key takeaways

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

Reference excerpt

The Lucifer titi monkey (Cheracebus lucifer) is a species of titi, a type of New World monkey, from South America. It is found in Brazil, Colombia, Ecuador, and Peru. It was described as Callicebus lucifer in 1914. The Lucifer titi has previously been treated as part of C. torquatus, the collared titi.

Distribution This species occurs near the interfluve north of the Solimões and Napo Rivers, and south of the Japurá River. The Lucifer titi is found in lowland Colombian Amazonia up to about 500 m (1,600 ft) of altitude in Putumayo and probably about the same in Caquetá. Outside of Colombia this species extends from the Napo River northward to the Ecuadorian Amazon.

Description The pelage of this species is basically blackish but intermixed with many hairs on the back (extending to the top of the crown) and flanks with many reddish brown hairs, giving the animal a definite reddish appearance in the sunlight.

Behavior

Reproduction Robinson et al. also report a birth season of December to January for the species in Peru at 4ºS. Why this specific birth season should be chosen by the species in such widely divergent places both north and south of the equator with different phenological cycles must remain for the moment an open question. The newborn quickly acclimates to being carried by the male, and usually goes to the female for nursing only.

Worked examples

Example 1 — a first encounter with Lucifer titi monkey

Start with the simplest possible case. Write down what Lucifer 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 Lucifer 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 Lucifer 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 Lucifer titi monkey

In research: Lucifer 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 Lucifer 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: Lucifer titi monkey is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arboreal mammals, Cheracebus, IUCN Red List least concern species, so understanding it makes those chapters shorter.
In everyday life: Look for Lucifer 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.
