Lesula

Lesula 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 Lesula rather than just read about it. In short: The lesula (Cercopithecus lomamiensis) is a species of Old World monkey in the guenon genus Cercopithecus, found in the Lomami Basin of the Congo. Though known to locals, it was unknown to the international scientific community until it was discovered in 2007 and confirmed in a 2012 publication.

Key takeaways

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

Reference excerpt

The lesula (Cercopithecus lomamiensis) is a species of Old World monkey in the guenon genus Cercopithecus, found in the Lomami Basin of the Congo. Though known to locals, it was unknown to the international scientific community until it was discovered in 2007 and confirmed in a 2012 publication. The lesula is the second new species of African monkey to be discovered since 1984. This monkey is described to have human looking eyes and a blue bottom "...and adult males have a huge bare patch of skin in the buttocks, testicles and perianal area," said John A. Hart, the researcher who described the monkey. "It's a brilliant blue, really pretty spectacular." The species was listed among the Top 10 New Species 2013 discovered in 2012 as selected by the International Institute for Species Exploration at Arizona State University out of more than 140 nominated species. Its distinctiveness is its human-like eyes, genital area and booming dawn chorus. The selection was declared on 22 May 2013.

Distribution

The lesula lives in rainforests in the Democratic Republic of Congo, with the 2007 specimen found in captivity in the village of Opala. Since that sighting, it has also been seen in the wild. Its range is between the Lomami and Tshuapa rivers in the central part of the country.

Status The lesula is vulnerable to hunting for bushmeat. Protecting the species could be challenging, as species with such a small range can go from vulnerable to seriously endangered in a few years. The lesula's range is within the Tshuapa–Lomami–Lualaba Conservation Landscape, and the Lomami National Park was created to protect this and other species in the region.

Behavior The lesula are generally described by researchers as quiet and shy. They also tend to usually live in small family groups of around five members or less. The Lesula's days consist of leisurely activities such as foraging for fruits and vegetation, grooming, and resting.

Worked examples

Example 1 — a first encounter with Lesula

Start with the simplest possible case. Write down what Lesula 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 Lesula 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 Lesula 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 Lesula

In research: Lesula 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 Lesula 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: Lesula is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arboreal mammals, Endemic fauna of the Democratic Republic of the Congo, Fauna of Central Africa, so understanding it makes those chapters shorter.
In everyday life: Look for Lesula 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.

Frequently asked questions

What is Lesula in simple terms?

Why does Lesula matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Lesula?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
