Steven Amstrup

Steven Amstrup is a astronomy 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 Steven Amstrup rather than just read about it. In short: Steven C. Amstrup (born February 4, 1950) is an American zoologist who studies bears, especially polar bears.

Key takeaways

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

Reference excerpt

Steven C. Amstrup (born February 4, 1950) is an American zoologist who studies bears, especially polar bears. He is the 2012 recipient of the Indianapolis Prize.

Early life Steven Amstrup was born in Fargo, North Dakota, where he took an interest in bears at an early age. He attended the University of Washington as an undergraduate, receiving his bachelor's degree in forestry in 1972. In 1975, he graduated from the University of Idaho with a master's degree in wildlife management. He studied black bears in central Idaho for his master's thesis. He earned his doctoral degree from the University of Alaska Fairbanks in 1995. In 1975, he began working for the United States Fish and Wildlife Service in Wyoming where he studied pronghorn antelope and sharp-tailed grouse. In 1980 he moved to Alaska where he took over the United States Fish and Wildlife Service's fledgling Polar Bear Research Project. In 1996 Amstrup's research position was transferred to the United States Geological Survey. During his 30-years in Alaska, he studied polar bear ecology, primarily in the Beaufort Sea. In 2007, Amstrup's team of scientists prepared nine reports leading to the 2008 listing, by United States Secretary of the Interior Dirk Kempthorne, of polar bears as a threatened species under the Endangered Species Act. In 2010, he published an article in Nature finding that even if climate change led to complete melting of the polar ice packs, the ice could return if global temperatures subsequently cooled. He has taught at the University of Wyoming as an adjunct professor since 2006. His contributions to polar bear conservation were honored in 2012, when the Indianapolis Zoo named him the winner of their biennial Indianapolis Prize. Later the same year, he was presented with an Our Earth Bambi Award in Düsseldorf.

Activism After retiring in 2010, Amstrup became the chief scientist for Polar Bears International. Having observed the effect of climate change on polar bears and their Arctic habitat during his career as a researcher, he now works as an advocate for polar bears and promotes climate change mitigation.

Personal life Amstrup is married. He and his wife are building an energy-efficient house in northeast Washington.

Worked examples

Example 1 — a first encounter with Steven Amstrup

Start with the simplest possible case. Write down what Steven Amstrup claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Steven Amstrup 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 Steven Amstrup 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 Steven Amstrup

In research: Steven Amstrup appears in astronomy 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 Steven Amstrup 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: Steven Amstrup is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1950 births, 21st-century American zoologists, American climate activists, so understanding it makes those chapters shorter.
In everyday life: Look for Steven Amstrup 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.
