Roosevelt's muntjac

Roosevelt's muntjac 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 Roosevelt's muntjac rather than just read about it. In short: A single specimen of the Roosevelt's muntjac or Roosevelt's barking deer (Muntiacus rooseveltorum) was presented to the Field Museum in 1929 following the Kelley-Roosevelts expedition organized by Theodore (Jnr) and Kermit Roosevelt. The specimen is slightly smaller than the common muntjac and DNA testing has shown it to be distinct from recently discovered muntjac species.

Key takeaways

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

Reference excerpt

A single specimen of the Roosevelt's muntjac or Roosevelt's barking deer (Muntiacus rooseveltorum) was presented to the Field Museum in 1929 following the Kelley-Roosevelts expedition organized by Theodore (Jnr) and Kermit Roosevelt. The specimen is slightly smaller than the common muntjac and DNA testing has shown it to be distinct from recently discovered muntjac species. It is a subspecies of Fea's muntjac, whose home range is mountains further northwest separated by lower land. However, without further evidence, the exact position of Roosevelt's muntjac cannot be stated. Berlin Zoo supposedly held this species between 1961 and 1972 (following an import from Northern Vietnam) but it could have been an Indian muntjac, subspecies annamensis. Roosevelt's muntjac was believed to have been extinct since 1929. However, there have been several recent claims to have rediscovered the species, from evidence including skulls owned by villagers in the Truong Son (Annamite) mountains of northern Laos and far northwestern Vietnam. More recently, photographs from a camera trap at Xuan Lien Nature Reserve in Vietnam appear to have identified two individuals.

Worked examples

Example 1 — a first encounter with Roosevelt's muntjac

Start with the simplest possible case. Write down what Roosevelt's muntjac 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 Roosevelt's muntjac 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 Roosevelt's muntjac 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 Roosevelt's muntjac

In research: Roosevelt's muntjac 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 Roosevelt's muntjac 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: Roosevelt's muntjac is common in secondary-school and first-year university syllabi. It links to neighbouring topics Artiodactyla stubs, IUCN Red List data deficient species, Mammals described in 1932, so understanding it makes those chapters shorter.
In everyday life: Look for Roosevelt's muntjac 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.
