Mitered langur

Mitered langur 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 Mitered langur rather than just read about it. In short: The mitered langur (Presbytis mitrata) is a species of monkey in the family Cercopithecidae. It was formerly considered a subspecies of the Sumatran surili, Presbytis melalophos (as Presbytis melalophos mitrata) but genetic analysis revealed that these are separate species.

Key takeaways

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

Reference excerpt

The mitered langur (Presbytis mitrata) is a species of monkey in the family Cercopithecidae. It was formerly considered a subspecies of the Sumatran surili, Presbytis melalophos (as Presbytis melalophos mitrata) but genetic analysis revealed that these are separate species. The mitered langur is native to the island of Sumatra in Indonesia. It is listed as vulnerable by the IUCN due primarily to deforestation, and also due to animals taken for pets. The mitered langur has gray or brown fur on its back, which is darker than on its belly, and the arms, legs and tail are even darker. Its face is gray, with white ruffs on its cheeks and a white crown surrounded by a black arch on the top of its head. The head and body length is between 42 centimetres (17 in) and 57 centimetres (22 in) and the tail is between 62 centimetres (24 in) and 82 centimetres (32 in) long. It weighs up to about 5.9 kilograms (13 lb). The mitered langur is diurnal and arboreal. Its diet consists of leaves, unripe fruits, flowers and seeds.

Worked examples

Example 1 — a first encounter with Mitered langur

Start with the simplest possible case. Write down what Mitered langur 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 Mitered langur 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 Mitered langur 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 Mitered langur

In research: Mitered langur 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 Mitered langur 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: Mitered langur is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arboreal mammals, Endangered fauna of Asia, Endemic fauna of Sumatra, so understanding it makes those chapters shorter.
In everyday life: Look for Mitered langur 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.
