Phoenix atlantica

Phoenix atlantica 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 Phoenix atlantica rather than just read about it. In short: Phoenix atlantica (common name Cape Verde Island date palm, local name: tamareira) is an endangered species in the palm family Arecaceae, in the genus Phoenix. It is endemic to the Cape Verde Islands.

Key takeaways

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

Reference excerpt

Phoenix atlantica (common name Cape Verde Island date palm, local name: tamareira) is an endangered species in the palm family Arecaceae, in the genus Phoenix. It is endemic to the Cape Verde Islands.

Overview

Phoenix atlantica is a relative of Phoenix dactylifera, the cultivated date palm. P. atlantica is clearly distinct from its close relatives and that its closest relative is likely to be its nearest geographical neighbour, P. dactylifera. The Cape Verde palm, is endemic to the Cape Verde Islands, and was erroneously characterized as a feral Phoenix dactylifera. Three species of the genus Phoenix are recorded from the Cape Verde Islands, P. dactylifera L., P. canariensis Chabaud and P. atlantica A. Chev. While human activity has almost certainly introduced the former two species, the latter is endemic to the islands. Genetic isolation of Cape Verde Island P. atlantica was revealed by microsatellite markers and one chloroplast minisatellite marker to individuals of Phoenix from the Cape Verde Islands, P. dactylifera, P. canariensis and P. sylvestris, in order to assess the taxonomic position of P. atlantica within the genus. The DNA analysis by S. A. Henderson, N. Billotte and J.-C. Pintaud, demonstrated Genetic isolation of Phoenix atlantica. Phoenix atlantica was first described in 1935 by the French botanist Auguste Chevalier. Its appearance is very similar to Phoenix dactylifera, being more similar in form to P. dactylifera than to Phoenix canariensis, and possessing characters of both. Tamareira is a clustering palm with 2 to 6 trunks, 5–15 m (16–49 ft) in height with dark green leaves 2–3 m (6.6–9.8 ft) in length. P. atlantica can be distinguished easily from P. canariensis by its clustering growth form and its shorter, straighter leaves. The Canary Island date palm is adapted to a wetter climate and cooler temperatures, down to −8 °C (18 °F). Other distinctions between P. atlantica and P. dactylifera include acuminate petals in the male flowers according to Chevalier in 1935, Greuter in 1967, and Brochmann et al. in 1997. The fruit is an oval, pink drupe 2 cm long and 1 cm diameter and containing a single large seed, the fruit pulp is edible but scarce.

Worked examples

Example 1 — a first encounter with Phoenix atlantica

Start with the simplest possible case. Write down what Phoenix atlantica 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 Phoenix atlantica 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 Phoenix atlantica 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 Phoenix atlantica

In research: Phoenix atlantica 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 Phoenix atlantica 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: Phoenix atlantica is common in secondary-school and first-year university syllabi. It links to neighbouring topics Drought-tolerant trees, Edible plants, Endemic flora of Cape Verde, so understanding it makes those chapters shorter.
In everyday life: Look for Phoenix atlantica 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.
