Courses
Dieses Modul befasst sich mit Fragen des angewandten Naturschutzes in Zeiten des Globalen Wandels. An konkreten Beispielen in Natur- und Kulturlandschaften (z.B. Natura 2000 Habitate) werden naturschutzfachliche Daten erhoben, ausgewertet und gemeinsam diskutiert. Aspekte des Biotop- und Artenschutzes, der angewandten Landschaftsplanung und eines nachhaltigen Naturschutzmanagements werden unter Einbindung von externen Experten aus der Praxis erörtert.
Exercises are held biweekly with 4 hours per session. There are a total of 6 dates covering the following topics:
1. introduction to ecological experimentation, sampling and analysis of biotic parameters.
2. measurement and significance of physical environmental factors using the example of atmospheric pressure and the solubility of oxygen as a function of temperature.
3. basic operations in the chemical laboratory and introduction to experimental work
4. introductory experiments on soil ecology
Part 1: Importance of soil acidity and soil colors - determination of pH and color of soil horizons
Part 2: Significance of soil types - Granulometric analysis and field method.

Dieses Modul vermittelt die Grundlagen der organismischen Biologie und führt in zentrale Konzepte wie Phylogenie, Artbegriff, Systematik, Taxonomie und Ökosystemfunktionen ein. Es behandelt die Hauptgruppen der Lebewesen: Prokaryoten (Bakterien, Archaeen) sowie ausgewählte Gruppen der Eukaryoten, insbesondere Pilze, Pflanzen und Tiere (einschließlich der Wirbeltiere) sowie die Flechten.
Darüber hinaus werden evolutionäre Zusammenhänge, Zellaufbau und die Keimblätter (Ecto-, Endo- und Mesoderm) erläutert. Die Studierenden erhalten eine Einführung in die grundlegenden Baupläne, Morphologie und Anatomie von Pflanzen- und Tierkörpern und entwickeln ein Basisverständnis ihrer strukturellen Organisation.
Praktische Übungen zu Mikroskopie, Präparation und biologischem Zeichnen vertiefen das Verständnis, ebenso wie die Themen Zellstruktur, Zellteilung und Zelldifferenzierung. Das Modul fördert zudem methodische Kompetenzen in biologischen Arbeitsweisen, Beobachtungstechniken und wissenschaftlichem Arbeiten.
