Ulf Hohmann

Ulf Hohmann 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 Ulf Hohmann rather than just read about it. In short: Ulf Hohmann (born 9 July 1963, in Stuttgart) is a German ethologist, whose studies about the raccoon have played a significant role in the understanding of its social behavior and its distribution in Germany. Biography Studying at the universities University of Tübingen and University of Kiel, Ulf Hohmann completed his diploma of Biology in 1992.

Key takeaways

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

Reference excerpt

Biography Studying at the universities University of Tübingen and University of Kiel, Ulf Hohmann completed his diploma of Biology in 1992. After the submission of his dissertation to Antal Festetics at the forestal faculty of the University of Göttingen in 1998, he was the chairperson of the Gesellschaft für Wildökologie und Naturschutz e.V. (Society for wildlife ecology and conservation e.V.). In this role, he appeared in the media as expert for the increasing urbanisation of animals. At the moment (July 2008), he works for the Forschungsanstalt für Waldökologie und Forstwirtschaft Rheinland-Pfalz (Research institute for forest ecology and forestry Rhineland-Palatinate) located in Trippstadt.

Research Within the scope of his dissertation, Ulf Hohmann and several scientific assistants carried out the first systematic study of the German raccoon population from 1992 to 1998. The telemetric measurement of the movement patterns of the raccoons living in the Lower Saxony low mountain range Solling yielded the result that the social behavior of raccoons is gender-specific and that they often live together in small, loose groups instead of being loners like previously thought. Stanley D. Gehrt arrived at the same conclusion in his study done in Texas in 1994 one year after Hohmann's initial query to Gehrt's doctoral adviser and raccoon expert Erik Fritzell about his discoveries. (→ Social behavior of raccoons) The study was supplemented with the observation of the behavior of several raised and subsequently released raccoon kits. This work, started by the graduand Franziska Kalz in 1995, was accompanied by the wildlife photographer Ingo Bartussek since spring 1996. Beginning in 1999, after the submission of his dissertation, Ulf Hohmann carried out the first study of urban raccoons outside of North America in the Hessian small town Bad Karlshafen. In 2001, Ulf Hohmann published the monograph Der Waschbär (The raccoon), giving a thorough overview of appearance and behavior of the species and the results of his studies in it. Besides numerous photos of Ingo Bartussek, the book also contains a chapter about raising raccoon kits written by the veterinarian Bernhard Böer. Working now for the Forschungsanstalt für Waldökologie und Forstwirtschaft Rheinland-Pfalz, Ulf Hohmann has recently concentrated on the research of boars, mainly of those living in the Palatinate Forest. His research on raccoons has been continued by Frank-Uwe Michler, who first worked together with Hohmann for his diploma in a study of urban raccoons in Kassel from 2001 to 2002. Since March 2006, Frank-Uwe Michler is the leader of the first study of the range and behavior of the raccoons living in the eastern parts of Germany in the Müritz National Park.

Worked examples

Example 1 — a first encounter with Ulf Hohmann

Start with the simplest possible case. Write down what Ulf Hohmann 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 Ulf Hohmann 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 Ulf Hohmann 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 Ulf Hohmann

In research: Ulf Hohmann 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 Ulf Hohmann 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: Ulf Hohmann is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1963 births, 20th-century German zoologists, 21st-century German zoologists, so understanding it makes those chapters shorter.
In everyday life: Look for Ulf Hohmann 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.
