Mendoza tuco-tuco

Mendoza 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 Mendoza tuco-tuco rather than just read about it. In short: The Mendoza tuco-tuco (Ctenomys mendocinus) is a species of rodent in the family Ctenomyidae. Taxonomy A 2021 phylogenetic study found that Azara's tuco-tuco (C. azarae) and Porteous's tuco-tuco (C. porteousi), which were both previously considered distinct species in Ctenomys, are synonymous with C. mendocinus.

Key takeaways

Mendoza 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 Mendoza tuco-tuco to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mendoza tuco-tuco from memory before moving on to harder problems.

Reference excerpt

The Mendoza tuco-tuco (Ctenomys mendocinus) is a species of rodent in the family Ctenomyidae.

Taxonomy A 2021 phylogenetic study found that Azara's tuco-tuco (C. azarae) and Porteous's tuco-tuco (C. porteousi), which were both previously considered distinct species in Ctenomys, are synonymous with C. mendocinus. The American Society of Mammalogists has followed this study's results. The former species was named after Spanish naturalist Félix de Azara, while the latter species was named after Lieutenant Colonel John James Porteous (1857–1948) and his nephew Don Cecil John Montague Porteous (1884– 1953), who owned land in Argentina.

Description Ctenomys mendocinus ranges from 230 to 280 mm (9.1 to 11.0 in) in body length, and tail length of 70–91 mm (2.8–3.6 in). Body mass ranges anywhere between 100 and 250 g (3.5 and 8.8 oz), with males typically larger than females. They have a stocky, robust body shape with short limbs and ears. Pelage is predominantly light-brown with subtle black and white coloration on its dorsal side, and a lightly colored tail. Forelimbs have long claws, necessary for burrowing.

Distribution The species is endemic to the northern and central regions of the Mendoza province in Argentina, at a range of elevation from 460 to 3,600 m (1,510 to 11,810 ft).

Behavior Members of this species engage in solitary burrowing behavior. Their foreleg claws are their primary method of digging tunnels through the ground, although the incisors may be used occasionally. They generally do not arise above the surface during the day time; however, they have a preference for above ground plant material and will surface to forage for food. Newborns are highly altricial: after a 3-month gestation period, pups are born half-naked and blind, weaning 56 days after birth and becoming independent after 80 days.

Diet The Mendoza tuco-tuco is an herbivore that feeds preferentially on grasses. Populations in the Andean Precordilla region of Mendoza display high selectivity for grasses and avoidance of shrubs with a preference for above ground plant material, despite a fossorial lifestyle and harsh environmental conditions that lower food availability.

Worked examples

Example 1 — a first encounter with Mendoza tuco-tuco

Start with the simplest possible case. Write down what Mendoza 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 Mendoza 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 Mendoza 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 Mendoza tuco-tuco

In research: Mendoza 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 Mendoza 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: Mendoza tuco-tuco is common in secondary-school and first-year university syllabi. It links to neighbouring topics Endemic rodentia species of Argentina, IUCN Red List least concern species, Mammals described in 1869, so understanding it makes those chapters shorter.
In everyday life: Look for Mendoza 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.
