Northern giant mouse lemur

Northern giant mouse lemur 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 Northern giant mouse lemur rather than just read about it. In short: The northern giant mouse lemur (Mirza zaza), or northern dwarf lemur, is a species of lemur discovered in 2005. They are part of the primate order, and classified in the family Cheirogaleidae.

Key takeaways

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

Reference excerpt

The northern giant mouse lemur (Mirza zaza), or northern dwarf lemur, is a species of lemur discovered in 2005. They are part of the primate order, and classified in the family Cheirogaleidae. Previously, both populations of giant mouse lemurs were believed to belong to one species. The northern giant mouse lemurs are small nocturnal lemurs endemic to Madagascar. They weigh about 300 grams (11 oz), and have long, bushy tails and relatively small ears. Their large testicles are an indication of their promiscuous copulation system. These lemurs have been found to use communal sleeping nests including multiple males, which is an uncommon behaviour in lemurs.

Etymology The word zaza means child in Malagasy. The name was chosen because the northern giant mouse lemur is the smaller of the two giant mouse lemur species, and because of a wish to emphasize the responsibility of the current generation of Malagasy children for the conservation of Malagasy animals for future generations.

Description The northern giant mouse lemur is relatively small, with juveniles weighing 150–199 g (5.3–7.0 oz), subadults 200–249 g (7.1–8.8 oz), and fully grown adults 250–300 g (8.8–10.6 oz). This species has large testes, among the largest relative testes to body size in the Primate order.

Distribution M. zaza are found in a strictly limited region in the north-western part of Madagascar, the Ampasindava peninsula. The habitat is split by two rivers, the Mahavavy River to the north and the Maevarano River to the south. In some areas it is further separated by the Sambirano River. This area in Madagascar has a dry and cool season from May to October, and a wet and hot season from November to April. The species can be found in a transition zone which goes to the Sambirano evergreen rainforest that extends to the north. Home ranges cover 0.52– 2.34 ha. There is no substantial overlap in home ranges among individuals. An estimated 385–1,086 individuals per km2 are present throughout the region.

Behavior The species has a polygynandrous mating system, likely based on the large size of the testes, which engenders strong sperm competition. Breeding is aseasonal. The northern mouse lemur is nocturnal, feeding predominantly during the second half of the night. On average, individuals stay approximately 7 metres (23 ft) up in the canopy. During the day they sleep in group-exclusive tree holes. Nesting groups are 2–8 individuals in size, made up of both sexes and any age class, and include unrelated males.

Conservation The species is classified as vulnerable by the IUCN primarily due to loss of habitat. The deciduous forests that they live in are being logged, fragmented, and degraded. The species is listed in CITES Appendix I.

Worked examples

Example 1 — a first encounter with Northern giant mouse lemur

Start with the simplest possible case. Write down what Northern giant mouse lemur 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 Northern giant mouse lemur 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 Northern giant mouse lemur 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 Northern giant mouse lemur

In research: Northern giant mouse lemur 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 Northern giant mouse lemur 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: Northern giant mouse lemur is common in secondary-school and first-year university syllabi. It links to neighbouring topics Arboreal mammals, Fauna listed on CITES Appendix I, IUCN Red List vulnerable species, so understanding it makes those chapters shorter.
In everyday life: Look for Northern giant mouse lemur 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.
