Sulawesi forest turtle

Sulawesi forest turtle 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 Sulawesi forest turtle rather than just read about it. In short: The Sulawesi forest turtle (Leucocephalon yuwonoi) is a critically endangered species of turtle in the family Geoemydidae. The species is monotypic within the genus Leucocephalon.

Key takeaways

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

Reference excerpt

The Sulawesi forest turtle (Leucocephalon yuwonoi) is a critically endangered species of turtle in the family Geoemydidae. The species is monotypic within the genus Leucocephalon. It is endemic to Sulawesi in Indonesia. These turtles have a unique clutch size, which is 1 or 2 eggs per clutch, that is significantly less than an average turtle's clutch size.

Etymology The specific name, yuwonoi, is in honor of Indonesian herpetologist Frank Bambang Yuwono (born 1958).

Habitat The preferred natural habitats of L. yuwonoi are freshwater swamps and rivers. They also prefer a heavily covered area rather than a more open area. They like broadleaf canopy cover and deeper ground cover.

Conservation Conservation methods are very important with species, due to very low numbers in this species and with people destroying their habitats for agriculture purposes. As of 2016 The Riverview Zoo in Peterborough, Ontario, had managed to hatch two Sulawesi forest turtles. As of 2022, there are only a few captive populations where we have been able to gain an understanding of Sulawesi forest turtles.

Worked examples

Example 1 — a first encounter with Sulawesi forest turtle

Start with the simplest possible case. Write down what Sulawesi forest turtle 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 Sulawesi forest turtle 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 Sulawesi forest turtle 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 Sulawesi forest turtle

In research: Sulawesi forest turtle 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 Sulawesi forest turtle 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: Sulawesi forest turtle is common in secondary-school and first-year university syllabi. It links to neighbouring topics Fauna listed on CITES Appendix II, Geoemydidae, IUCN Red List critically endangered species, so understanding it makes those chapters shorter.
In everyday life: Look for Sulawesi forest turtle 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.
