Seal's sportive lemur

Seal's sportive 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 Seal's sportive lemur rather than just read about it. In short: Seal's sportive lemur (Lepilemur seali), or the Anjanaharibe-Sud sportive lemur, is a sportive lemur endemic to Madagascar. Previous to a 2006 genetic analysis showing the species to be distinct, it was thought to be a population of weasel sportive lemur (Lepilemur mustelinus).

Reference excerpt

Seal's sportive lemur (Lepilemur seali), or the Anjanaharibe-Sud sportive lemur, is a sportive lemur endemic to Madagascar. Previous to a 2006 genetic analysis showing the species to be distinct, it was thought to be a population of weasel sportive lemur (Lepilemur mustelinus). Like all members of its genus, it is nocturnal and largely folivorous. It is threatened by habitat loss, hunting, and climate change.

Evolution Seal's sportive lemur is a sister species to Holland's sportive lemur (Lepilemur hollandorum), having diverged approximately 2.1 million years ago. These two species further fall into a northeastern Lepilemur clade with Scott's sportive lemur (Lepilemur scottorum) that originated approximately 2.68 million years ago.

Description Seal's sportive lemur has long, thick fur that is uniformly light chocolate-brown to reddish-brown above and lighter brownish grey below with cream-tipped hairs on the sides of the belly. The face is light brownish grey, with a yellow to white collar on the neck. The hands and feet are light, greyish brown. The tail is brownish grey, and sometimes possesses white-tipped hairs. It is a medium-sized Lepilemur, with a total length of 53 cm (21 in), of which 27 cm (11 in) is the body and 26 cm (10 in) is the tail. It weighs approximately 950 g (34 oz).

Distribution and habitat Seal's sportive lemur is found in northeastern Madagascar, where it is known at least as far south as the Fananehana River and no farther north than the Bernarivo River. However, the exact boundaries of the species' range are not clear. Within its distribution, Seal's Sportive Lemur occupies mid to high altitude humid rainforests, preferring undisturbed low-canopy forests that have good availability of sleeping holes in old trees.

Threats and conservation The main threats facing Seal's sportive lemur are habitat loss, hunting and climate change. The rainforests in which the species inhabit are under direct threat due to forest clearing for shifting agriculture. Additionally, hunting of the species is unsustainable, with local households on average hunting 0.15 Seal's sportive lemurs per year, among 1,155 households in the surveyed region. The species' distribution is also expected to shrink by 8% by 2080 due to climate change alone. Seal's sportive lemur occurs in some protected areas such as the Anjanaharibe-Sud Special Reserve and Makira Natural Park.

Worked examples

Example 1 — a first encounter with Seal's sportive lemur

Start with the simplest possible case. Write down what Seal's sportive 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 Seal's sportive 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 Seal's sportive 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 Seal's sportive lemur

In research: Seal's sportive 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 Seal's sportive 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: Seal's sportive 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 Seal's sportive 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.
