Goodfellow's tuco-tuco

Goodfellow's tuco-tuco 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 Goodfellow's tuco-tuco rather than just read about it. In short: Goodfellow's tuco-tuco (Ctenomys goodfellowi) is a species of rodent in the family Ctenomyidae. It is endemic to Bolivia, where it is found in the Chiquitano dry forest ecoregion, bordering on the cerrado.

Key takeaways

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

Reference excerpt

Goodfellow's tuco-tuco (Ctenomys goodfellowi) is a species of rodent in the family Ctenomyidae. It is endemic to Bolivia, where it is found in the Chiquitano dry forest ecoregion, bordering on the cerrado. Its karyotype has 2n = 46 and FN = 68. The species is named after British collector Walter Goodfellow.

Worked examples

Example 1 — a first encounter with Goodfellow's tuco-tuco

Start with the simplest possible case. Write down what Goodfellow's tuco-tuco 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 Goodfellow's tuco-tuco 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 Goodfellow's tuco-tuco 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 Goodfellow's tuco-tuco

In research: Goodfellow's tuco-tuco 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 Goodfellow's tuco-tuco 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: Goodfellow's tuco-tuco is common in secondary-school and first-year university syllabi. It links to neighbouring topics Endemic fauna of Bolivia, IUCN Red List least concern species, Mammals described in 1921, so understanding it makes those chapters shorter.
In everyday life: Look for Goodfellow's tuco-tuco 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.
