Petra Deimer

Petra Deimer 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 Petra Deimer rather than just read about it. In short: Petra Deimer (9 March 1948, in Göttingen – 27 March 2024) was a German marine biologist, and nature conservationist who has been actively involved in the study and protection of marine mammals, particularly cetaceans, since the mid-1970s. Career Deimer gained her PhD in marine biology, with a particular focus on sperm whales, at the University of Hamburg.

Key takeaways

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

Reference excerpt

Petra Deimer (9 March 1948, in Göttingen – 27 March 2024) was a German marine biologist, and nature conservationist who has been actively involved in the study and protection of marine mammals, particularly cetaceans, since the mid-1970s.

Career Deimer gained her PhD in marine biology, with a particular focus on sperm whales, at the University of Hamburg. In the late 1970s many species of whale, including sperm whales, were in danger of extinction. As a result of Deimer's actions, the archipelago of Madeira was declared a protection zone for marine mammals, and commercial whaling around Madeira ceased in 1981. She contributed significantly to the decision of the International Whaling Commission (IWC) to ban commercial whaling in July 1982. In 1983 Deimer ensured that the trade in Minke whales was also banned. Deimer is the founder and president of the Society for the Conservation of Marine Mammals (Gesellschaft zum Schutz der Meeressäugetiere; GSM). She is a member of the International Whaling Commission's (IWC) Scientific Committee, a member of the German government's Species Conservation Advisory Committee, and an advisor to the International Fund for Animal Welfare (IFAW). In 2001, Deimer was awarded the Golden Ark for nature conservation by Prince Bernhard of the Netherlands. Deimer has written six books, and numerous articles on whales, dolphins, and seals, as well as on environmental conservation more generally. She has also written a book on parrots.

Worked examples

Example 1 — a first encounter with Petra Deimer

Start with the simplest possible case. Write down what Petra Deimer 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 Petra Deimer 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 Petra Deimer 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 Petra Deimer

In research: Petra Deimer 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 Petra Deimer 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: Petra Deimer is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1948 births, 2024 deaths, Cetologists, so understanding it makes those chapters shorter.
In everyday life: Look for Petra Deimer 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.
