List of macroscelids

List of macroscelids 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 macroscelids rather than just read about it. In short: Macroscelidea is an order of small mammals. Members of this order are called macroscelids, or commonly as sengis or elephant shrews.

Key takeaways

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

Reference excerpt

Macroscelidea is an order of small mammals. Members of this order are called macroscelids, or commonly as sengis or elephant shrews. They are exclusively found in Africa, in a variety of biomes from forests to deserts. They range in size from the Etendeka round-eared sengi, at 8 cm (3 in) plus a 8 cm (3 in) tail, to the grey-faced sengi, at 32 cm (13 in) plus a 26 cm (10 in) tail, and generally eat insects, other invertebrates, and plants. The only macroscelid species with an International Union for Conservation of Nature (IUCN) population estimate is the golden-rumped sengi, listed as endangered with a population of around 13,000. The nineteen extant species of Macroscelidea are grouped into a single family, Macroscelididae, and are split between six genera. Dozens of extinct macroscelid 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 IUCN Red List of Threatened Species. Range maps are provided wherever possible; if a range map is not available, a description of the macroscelid's range is provided. Ranges are based on the IUCN Red List for that species unless otherwise noted. All extinct species or subspecies listed alongside extant species went extinct after 1500 CE, and are indicated by a dagger symbol "†".

Classification The order Macroscelidea consists of a single family, Macroscelididae, which contains twenty species divided into six genera. Many of these species are further subdivided into subspecies. This does not include hybrid species or extinct prehistoric species.

Macroscelids The following classification is based on the taxonomy described by Mammal Species of the World (2005), with augmentation by generally accepted proposals made since using molecular phylogenetic analysis.

Worked examples

Example 1 — a first encounter with List of macroscelids

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

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