    Ecology

    Further topics include aspects of Sociobiolgy, constraints for plant growth and development (biogeography, biodiversity), the interactions of plants and animals with abiotic and biotic environmental factors, the interaction of individuals, social groups and large populations in complex and variable ecosystems.

    PROGRAMME OUTLINES

    Programme Profile: Ecology

    The multidisciplinary programme combines plant ecology, animal ecology, conservation biology and tropical biology. These topics include animal-plant interactions, plant ecophysiology, biodiversity research, climate-change ecology, and the evolutionary adaptations at the physiological and organismic level. Courses in socio-biology, neurogenetics and behaviour as well as ecological courses like forest ecology, chemical ecology, agroecology, soil ecology, remote sensing and ecological modelling can be chosen. Overall, the study program reaches from molecular biology of single species to all disciplines of organismic biology. Further topics include constraints for plant growth and development (biogeography, biodiversity), the interactions of plants and animals with abiotic and biotic environmental factors (e.g. plant-insect, plant-fungus interactions) including the evolutionary adaptations at the physiological and organismic level, aspects of neurogenetics and behaviour as well as the interaction of individuals, social groups and large populations in complex and variable ecosystems.  Using tropical biology with its specialties, unique and general principles in ecology are communicated. Both fundamentals and novel approaches based on molecular biology tools are discussed with respect to organismic biology. The two selected topics are composed of two theory modules as well as a practical course unit each. Further research training is provided in a selected field of interest, and the students are actively involved in ongoing research projects and learn to independently plan and perform both theoretical and experimental work and finally, to summarize and discuss the results obtained in the thesis.  

    Objectives and Learning Outcomes

    On the background of a bachelor degree in Biology/Life Sciences, the students learn various aspects, principles and experimental approaches in animal and plant ecology with a special focus on tropical ecosystems. With several bioinformatics tools, they become familiar how to use computer based approaches in order to address and resolve problems in these bioscientific fields. The students are enabled to address scientific questions with regard to organismic interactions, ecosystems, biodiversity, environmental protection. They know to approach scientific problems both theoretically and experimentally, and - based on the results obtained - to further develop scientific models and hypotheses.  

    STUDY PROGRAMME

    Modules - Theory

    Animal Ecology and Tropical Biology

    C: The course provides insights into basic principles in ecology with particular focus on the biology of tropical habitats including tropical biocenosis.  Special attention is given to the global importance of tropical systems (“ecosystem  goods” and “ecosystem  services”)  as well as to biological specialties and aspects of particular adaption in  these highly diverse biomes. 

    LO: The students become qualified to recognize the exceptional functional position of tropical habitats within the biosphere and to also explain their importance within our ecosystem.  They are able to evaluate the consequences of manipulating those tropical systems and can judge relevant issues on environmental protection. The students become familiar with a variety of aspects on the biological specialties and structural characteristics of tropical systems.

    In the seminar the students learn to perform problem based scientific literature research, to present recent publications and to critically discuss these new findings.  

    Plant Ecology

    C: The lecture will deal with the ecological and environmental constraints under which plants grow and develop (biogeography, biodiversity) and with the interactions of plants with abiotic and biotic environmental factors (e.g. plant-insect, plant-fungus interactions). Especially, the evolutionary adaptations on the physiological and organismic level will be emphasized (stress and defense reactions, carnivory, plant protection). Corresponding experimental approaches are illustrated. The seminar deepens the topics covered by the lecture based on selected examples from current research and is complemented by topic-related guided tours in the Botanical Garden of the University of Würzburg.

    Molecular Biology (Lecture Series)

    C: Molecular Biology of Procaryotic and Eucaryotic Cells. The lecture series introduces into the fields of cell biology, developmental biology, microbiology, biophysics, bioinformatics. Based on current concepts in molecular biology, the lectures elucidate these with respect to the particular disciplines. 

    Recommended literature: Alberts B, Bray D. et al. "Essential Cell Biology"; Garland Science, NY USA 

    In the course sessions on “Cell Biology“ (comprising 25% of the total) focuses on  the eucaryotic cell and illustrates both the fundamental principles of molecular cell biology and the huge structural and functional diversity of molecules, organelles and cells.

    The lectures on bioinformatics (25% of total) comprise many examples for application in order to demonstrate how to address problems in molecular biology with tools of bioinformatics. The lectures are in line with the textbook „Essential Cell Biology“, and include many examples covering the topics of all course sessions. Bioinformatics is presented as a computer based molecular biology tool allowing time saving experimental planning.   

    The third part of the lecture series is dealing with fundamental aspects of prokaryotes and microbiology in general. Special topics are the organization of the bacterial genome, the machinery and regulation of transcription and translation, the transport of cellular components, cell division and   cellular differentiation processes, bacterial mobility and chemotaxis, signal transduction and bacterial communication.       

    Recommended literature:

    (a) Allgemeine Mikrobiologie (Fuchs)  (b) Madigan MT, Martinko JM, Stahl DA Clark DP Brock Biology of Microorganisms. Pearson educ., USA

    LO: The students become familiar with theoretical aspects and principles in cell biology, developmental biology, microbiology, biophysics, bioinformatics. With several bioinformatics tools, they become familiar how to use computer based approaches to address and resolve problems in these bioscientific fields. 

    Neurobiology, Behavioural Physiology and Animal Ecology (Lecture series)

    C: "Timing matters":  Temporal organization in the animal kingdom

    Timing plays an important role in all living systems. Animals make use of endogenous clocks to predict and adapt to daily or seasonal changes in environmental parameters. To be at the right time at the right place is of great fitness relevance if -for example- a mating partner or enough food has to be found. Many mutualistic, antagonistic or social interactions can only take place if animals are at the same time at the same place and in the appropriate developmental stage.

    The lecture series give an introduction into the mechanisms underlying the temporal organization in the animal kingdom. Adopting an integrative approach, the lecture goes from timing mechanisms on the neuronal level to individual behaviour and then to interactions in social groups, populations or partners in complex and variable ecosystems.

    LO: The students get an overview in organismic biology including neurobiology, behavioral biology and ecology. They experience the complex interactions of living organisms including the importance of time and place to result in successful reproduction or synergy.
