List of ctenomyids

List of ctenomyids 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 List of ctenomyids rather than just read about it. In short: Ctenomyidae is a family of fossorial mammals in the order Rodentia and part of the Caviomorpha parvorder. Members of this family are called ctenomyids or tuco-tucos.

Key takeaways

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

Reference excerpt

Ctenomyidae is a family of fossorial mammals in the order Rodentia and part of the Caviomorpha parvorder. Members of this family are called ctenomyids or tuco-tucos. They are found in southern South America, primarily in shrublands and grasslands, though some species can be found in forests, savannas, deserts, wetlands, and coastal areas. They range in size from the white-toothed tuco-tuco, at 11 cm (4 in) plus a 7 cm (3 in) tail, to Conover's tuco-tuco, at 33 cm (13 in) plus a 11 cm (4 in) tail. Ctenomyids are herbivores and eat a wide variety of vegetation. No ctenomyids have population estimates, but ten species are categorized as an endangered species, and four—the Peruvian tuco-tuco, Reig's tuco-tuco, Roig's tuco-tuco, and the social tuco-tuco—are categorized as critically endangered. The 59 extant species of Ctenomyidae are all contained in a single genus, Ctenomys. A few extinct prehistoric ctenomyid species have been discovered, though due to ongoing research and discoveries, the exact number and categorization is not fixed.

Conventions

The author citation for the species or genus is given after the scientific name; parentheses around the author citation indicate that this was not the original taxonomic placement. Conservation status codes listed follow the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the ctenomyid's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted.

Classification Ctenomyidae is a family consisting of 59 extant species in a single genus, Ctenomys. This does not include hybrid species or extinct prehistoric species.

Ctenomyids The following classification is based on the taxonomy described by the reference work Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis, as supported by both the IUCN and the American Society of Mammalogists.

Worked examples

Example 1 — a first encounter with List of ctenomyids

Start with the simplest possible case. Write down what List of ctenomyids 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 List of ctenomyids 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 List of ctenomyids 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 List of ctenomyids

In research: List of ctenomyids 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 List of ctenomyids 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: List of ctenomyids is common in secondary-school and first-year university syllabi. It links to neighbouring topics Lists of animal species, Lists of rodents, Tuco-tucos, so understanding it makes those chapters shorter.
In everyday life: Look for List of ctenomyids 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.
