Invasive species of New Zealand origin

Invasive species of New Zealand origin 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 Invasive species of New Zealand origin rather than just read about it. In short: Some species endemic to New Zealand are causing problems in other countries, similar to the way introduced species in New Zealand cause problems for agriculture and indigenous biodiversity. Animals The New Zealand mud snail (Potamopyrgus antipodarum) is an invasive species in many countries and has been present in Europe since 1859.

Key takeaways

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

Reference excerpt

Some species endemic to New Zealand are causing problems in other countries, similar to the way introduced species in New Zealand cause problems for agriculture and indigenous biodiversity.

Animals The New Zealand mud snail (Potamopyrgus antipodarum) is an invasive species in many countries and has been present in Europe since 1859. The New Zealand flatworm (Arthurdendyus triangulatus) is an invasive species in Europe where it preys on earthworms and degrades soil quality. Weka (Gallirallus australis) were introduced to several islands south of New Zealand, including Macquarie Island in the 1870s, where the weka was utilized as a food source. However, despite their survivability against other predators to islands it is not native to, the weka became a pest by outcompeting prey against native birds, and is claimed to have contributed to the extinction of the Macquarie parakeet and a native species of land rail. The weka population in Macquarie Island declined in the 1980s and was fully eradicated in 1988.

Plants Taupata (Coprosma repens), also known as mirror bush, looking-glass bush, New Zealand laurel or shiny leaf, is a weed in Australia, Norfolk Island, South Africa and the U.S. (California and Hawaii). Pōhutukawa (Metrosideros excelsa), sometimes called the New Zealand Christmas tree, is an invasive species in South Africa. The biddy biddy (Acaena novae-zelandiae) is declared a noxious weed in the American states of Hawaii, California and Oregon. It is also a problem plant in Northumberland. New Zealand flax or harakeke (Phormium tenax) is an invasive species in St Helena, some Pacific islands and in Australia. Pohuehue (Muehlenbeckia complexa), also called wire vine, mattress vine and several other common names, is naturalised in Western Australia. Although it is a valued garden plant, it can become a pest in suitable climates (e.g. San Francisco's Golden Gate National Recreation Area) if not contained. Mānuka (Leptospermum scoparium) and kānuka (Kunzea ericoides) were planted in Hawaii during the early 20th century and have infested several islands. Ngaio (Myoporum laetum) forms dense thickets in coastal areas of Southern California and Mexico and is therefore a serious weed.

Worked examples

Example 1 — a first encounter with Invasive species of New Zealand origin

Start with the simplest possible case. Write down what Invasive species of New Zealand origin 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 Invasive species of New Zealand origin 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 Invasive species of New Zealand origin 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 Invasive species of New Zealand origin

In research: Invasive species of New Zealand origin 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 Invasive species of New Zealand origin 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: Invasive species of New Zealand origin is common in secondary-school and first-year university syllabi. It links to neighbouring topics Biota of New Zealand, Invasive species, so understanding it makes those chapters shorter.
In everyday life: Look for Invasive species of New Zealand origin 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.
