Juniperus drupacea

Juniperus drupacea 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 Juniperus drupacea rather than just read about it. In short: Juniperus drupacea, the Syrian juniper, is a species of juniper native to the eastern Mediterranean region from southern Greece (mount Parnon in the Peloponnese), southern Turkey, western Syria, Lebanon, and northern Israel, growing on rocky sites from 800–1,700 metres (2,600–5,600 feet) in altitude. The species is the sole member of Juniperus sect.

Key takeaways

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

Reference excerpt

Juniperus drupacea, the Syrian juniper, is a species of juniper native to the eastern Mediterranean region from southern Greece (mount Parnon in the Peloponnese), southern Turkey, western Syria, Lebanon, and northern Israel, growing on rocky sites from 800–1,700 metres (2,600–5,600 feet) in altitude. The species is the sole member of Juniperus sect. Caryocedrus., which is sometimes recognised as genus Arceuthos.

Description Juniperus drupacea is the tallest species of juniper, forming a conical tree 10–25 metres (33–82 feet) tall, exceptionally up to 40 m (130 ft), and with a trunk up to 1–2 m (3+1⁄2–6+1⁄2 ft) thick. It has needle-like leaves in whorls of three; the leaves are green, 5–25 millimetres (1⁄4–1 in) long and 2–3 mm broad, with a double white stomatal band (split by a green midrib) on the inner surface. It is usually dioecious, with separate male and female plants. The seed cones are the largest of any juniper, berry-like but hard and dry, green ripening in about 25 months to dark purple-brown with a pale blue waxy coating; they are ovoid to spherical, 20–27 mm (3⁄4–1 in) long and 20–25 mm diameter, and have six or nine fused scales in 2–3 whorls, each scale with a slightly raised apex. The three apical scales each bear a single seed, but with the three seeds fused together into a single nut-like shell. The male cones are produced in clusters (unlike any other juniper) of 5–20 cones together, yellow, 3–4 mm long, and fall soon after shedding their pollen in early spring.

Taxonomy Because of its distinct cones with the seeds fused three together and the clustered male cones, it has sometimes been treated in a distinct genus of its own as Arceuthos drupacea (Labill.) Antoine & Kotschy, but genetic studies have shown it is fairly closely related to J. macrocarpa and J. oxycedrus.

Culinary and Medicinal Uses In Southeastern Turkey, on mountainsides of Enekli Tepe, the fruit is boiled into an edible concentrate, to be preserved, and then consumed. This solution is called pekmez, and in addition to being nutritious, and promoting energy, is seen as an aphrodisiac. It is also used to treat asthma. Additional time-honoured medicinal uses for the tree in Turkey include treatment of haemorrhoids, stomach ailments, urinary infections, gout, wounds, diarrhoea, cough, and ordinary cold symptoms.

Worked examples

Example 1 — a first encounter with Juniperus drupacea

Start with the simplest possible case. Write down what Juniperus drupacea 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 Juniperus drupacea 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 Juniperus drupacea 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 Juniperus drupacea

In research
Juniperus drupacea 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 Juniperus drupacea 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
Juniperus drupacea is common in secondary-school and first-year university syllabi. It links to neighbouring topics Dioecious plants, IUCN Red List least concern species, Juniperus, so understanding it makes those chapters shorter.
In everyday life
Look for Juniperus drupacea 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.
