Guajira–Barranquilla xeric scrub is a science 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 Guajira–Barranquilla xeric scrub rather than just read about it. In short: The Guajira–Barranquilla xeric scrub is a xeric shrubland ecoregion in Colombia, Venezuela, and the ABC Islands (Leeward Antilles), covering an estimated area of 150,000 km2 (58,000 sq mi). Rainfall varies from 125 to 600 mm (4.9 to 23.6 in), and the median temperature is 26 °C (79 °F).

Reference excerpt

The Guajira–Barranquilla xeric scrub is a xeric shrubland ecoregion in Colombia, Venezuela, and the ABC Islands (Leeward Antilles), covering an estimated area of 150,000 km2 (58,000 sq mi). Rainfall varies from 125 to 600 mm (4.9 to 23.6 in), and the median temperature is 26 °C (79 °F).

Location

The ecoregion occupies the Guajira Peninsula, the valley of the Rancheria river and Guajira Department, covering parts of the northeastern coast of Venezuela to the ABC Islands (Leeward Antilles). The valleys lie in the rain shadow of the surrounding Serranía de Macuira, which reaches an elevation of 900 m (3,000 ft) over sea level. These mountains trap some of the trade winds, causing mist. An important tourist destination in the area is Cabo de la Vela, and Klein Curaçao.

Ecology

Flora

The ecoregion is dominated by thorny trees and succulents. Common species include Acacia glomerosa, Bourreria cumanensis, Bulnesia arborea, Caesalpinia coriaria, Copaifera venezolana, Croton sp., Gyrocarpus americanus, Hyptis sp., Jacquinia pungens, Malpighia glabra, Myrospermum frutescens, Opuntia caribaea, Pereskia guamacho, Piptadenia flava, Prosopis juliflora, and Stenocereus griseus.

Forests dominated by Lonchocarpus punctatus are often accompanied by Bunchosia odorata and Ayenia magna. Other forests exist in which Prosopis juliflora, Erythrina velutina and Clerodendron ternifolium are dominant. A variety of plant communities occur where two plant species are dominant. Examples include Astronium graveolens – Handroanthus billbergii, Haematoxylum brasiletto – Melochia tomentosa, Caesalpinia coriaria – Cordia curassavica, Bursera glabra – Castela erecta, Vitex cymosa – Libidibia coraria, Mimosa cabrera – Cordia curassavica, Bursera tomentosa – Bursera graveolens and Castela erecta – Parkinsonia praecox.

Fauna

The ecoregion is notable for being the habitat of a large community of Caribbean flamingo (Phoenicopterus ruber), besides a diversity of birds and bats.

Conservation Most of the Serranía de Macuira lies within National Natural Park of Macuira. Nearby is the 80 km2 (31 sq mi) Los Flamencos Sanctuary, which is a center of plant diversity for species of Hechtia, Salvia, and cactus. Of the 2700 species found within, approximately 30% are endemic.

Worked examples

Example 1 — a first encounter with Guajira–Barranquilla xeric scrub

Start with the simplest possible case. Write down what Guajira–Barranquilla xeric scrub claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Guajira–Barranquilla xeric scrub 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 Guajira–Barranquilla xeric scrub 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 Guajira–Barranquilla xeric scrub

In research: Guajira–Barranquilla xeric scrub appears in science 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 Guajira–Barranquilla xeric scrub 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: Guajira–Barranquilla xeric scrub is common in secondary-school and first-year university syllabi. It links to neighbouring topics Deserts and xeric shrublands, Deserts of Colombia, Deserts of Venezuela, so understanding it makes those chapters shorter.
In everyday life: Look for Guajira–Barranquilla xeric scrub 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.
