Reinhardt Kristensen

Reinhardt Kristensen 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 Reinhardt Kristensen rather than just read about it. In short: Reinhardt Møbjerg Kristensen (born 1948) is a Danish invertebrate biologist, noted for the discovery of three new phyla of microscopic animals: the Loricifera in 1983, the Cycliophora in 1995, and the Micrognathozoa in 2000. He is also considered one of the world's leading experts on tardigrades.

Key takeaways

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

Reference excerpt

Reinhardt Møbjerg Kristensen (born 1948) is a Danish invertebrate biologist, noted for the discovery of three new phyla of microscopic animals: the Loricifera in 1983, the Cycliophora in 1995, and the Micrognathozoa in 2000. He is also considered one of the world's leading experts on tardigrades. His recent field of work revolves mostly around arctic biology. He is also known for documenting Dendrogramma, an invertebrate genus that was later classified as Siphonophorae of the family Rhodaliidae.

Loricifera

Kristensen collected the first members of the Loricifera phylum in Roscoff, France, in 1970, but did not describe it until 1983.

Cycliophora Kristensen and Peter Funch described Symbion pandora, on the mouth-parts of Norwegian lobsters, in 1995; other species were later found on other types of lobsters.

Micrognathozoa Kristensen described Limnognathia maerski, the first (and so far only) known species in the group, in a cold spring on Disko Island in 2000.

Worked examples

Example 1 — a first encounter with Reinhardt Kristensen

Start with the simplest possible case. Write down what Reinhardt Kristensen 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 Reinhardt Kristensen 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 Reinhardt Kristensen 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 Reinhardt Kristensen

In research: Reinhardt Kristensen 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 Reinhardt Kristensen 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: Reinhardt Kristensen is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 births, Danish scientist stubs, Danish zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Reinhardt Kristensen 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.
