Preuss's red colobus

Preuss's red colobus 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 Preuss's red colobus rather than just read about it. In short: Preuss's red colobus (Piliocolobus preussi) is a red colobus primate species endemic to the Cross-Sanaga Rivers ecoregion. An important population occurs in Korup National Park, Southwest Province, Cameroon, but the species' distribution is localized (groups are frequently encountered near the main tourist camps).

Key takeaways

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

Reference excerpt

Preuss's red colobus (Piliocolobus preussi) is a red colobus primate species endemic to the Cross-Sanaga Rivers ecoregion. An important population occurs in Korup National Park, Southwest Province, Cameroon, but the species' distribution is localized (groups are frequently encountered near the main tourist camps). The species is considered present in adjacent Cross River National Park - Oban Division in Nigeria and hunter reports suggest that few groups remain in Nkwende Hills and Nta Ali Forest Reserve in the broader Korup region. A population is also present in Ebo forest, Littoral Province of Cameroon.

Conservation status Preuss's red colobus is critically endangered according to the IUCN Red List due to hunting pressure and the destruction of its habitat. A large portion of the remaining groups are included within protected areas (Korup National Park, Cross River National Park, and the proposed national park at Ebo).

Ecology Like other colobus monkeys, it is primarily a leaf eater.

Description Preuss's red colobus has a black head, a black back ticked with orange, and bright red tail, limbs and cheeks.

Taxonomy Preuss's red colobus has, in the past, been considered a subspecies of P. pennantii and P. badius.

Worked examples

Example 1 — a first encounter with Preuss's red colobus

Start with the simplest possible case. Write down what Preuss's red colobus 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 Preuss's red colobus 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 Preuss's red colobus 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 Preuss's red colobus

In research: Preuss's red colobus 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 Preuss's red colobus 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: Preuss's red colobus is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arboreal mammals, Critically endangered fauna of Africa, IUCN Red List critically endangered species, so understanding it makes those chapters shorter.
In everyday life: Look for Preuss's red colobus 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.
