701-0034-12LIntegrated Practical: Plant Ecology: From Theory to Practice Restricted registration - show details 3 credits3PJ. Hille Ris Lambers, J.  Alexander
AbstractIn this practical class, students investigate how the plant species composition of grasslands depends on management and soil conditions. They learn how to survey the composition of plant communities and how to plan, realise and analyse field experiments. They will understand how the traits of grassland species determine their response to management, and how this knowledge is applied in practice.
ObjectiveStudents will be able to:
- Identify grassland plant species.
- Recognize grassland types from their structure and species composition, and explain how they depend on soil conditions, microclimate and management.
- Describe and explain changes in grassland composition after establishment and implications for grassland use.
- Survey plant species composition and vegetation structure with established methods.
- Carry out a field survey or a field experiment with a correct design; analyse the resulting data.
ContentWir führen Untersuchungen an der ETH Hönggerberg und in der Umgebung durch, um die Funktionsweise und Nutzung von Wiesen (Grünland) zu verstehen.
Wir vergleichen verschieden genutze Gründlandtypen miteinander: wie können wir sie schnell erkennen und ökologisch einordnen?
Für das Praktikum nutzen wir Versuchsflächen die eine unterschiedliche Bodenzusammensetzung aufweisen. Wir führen dort Vegetationsaufnahmen durch und analysieren den Einfluss des Bodens auf die Artzusammensetzungen und deren Verlauf mit der Zeit. Die Daten werden ausgewertet und diskutiert.
Lecture notesHandouts will be supplied in class.
LiteratureSpecialized literature will be available during classes
Prerequisites / NoticeBei den Felduntersuchungen sind gute Kleidung und Schuhe, Sonnen- und Regenschutz, sowie Massnahmen gegen Zeckenkrankheiten notwendig; die TeilnehmerInnen sind hierfür selbst verantwortlich.

Enrolment ONLY for MSc students with a decree declaring this course unit as an additional admission requirement.

Any other students (e.g. incoming exchange students, doctoral students) CANNOT enrol for this course unit.
3 credits6RJ.  Alexander
AbstractThis course assigns reading for students needing further background for understanding ecological processes. Central problems in ecology, including population growth and regulation, the dynamics of species interactions, the influence of spatial structure, the controls over species invasions, and community responses to environmental change will be explored from basic and applied perspectives.
ObjectiveStudents will understand how ecological processes operate in natural communities. They will appreciate how mathematical theory, field experimentation, and observational studies combine to generate a predictive science of ecological processes.

Upon completing the course, students will be able to:

Understand the factors determining the outcome of species interactions in communities, and how this information informs management.

Apply theoretical knowledge on species interactions to predict the potential outcomes of novel species introductions.

Understanding the role of spatial structure in mediating population dynamics and persistence, species interactions, and patterns of species diversity.

Use population and community models to predict the stability of interactions between predators and prey and between different competitors.

Understand the conceptual basis of predictions concerning how ecological communities will respond to climate change.
ContentReadings from a text book will focus on understanding central processes in community ecology. Topics will include demographic and spatial structure, consumer resource interactions, food webs, competition, invasion, and the maintenance of species diversity. Each of these more conceptual topics will be discussed in concert with their applications to the conservation and management of species and communities in a changing world.
701-0323-00LPlant Ecology3 credits2VJ.  Alexander
AbstractThis class focuses on ecological processes involved with plant life, mechanisms of plant adaptation, plant-animal and plant-soil interactions, plant strategies and implications for the structure and function of plant communities. The discussion of original research examples familiarises students with research questions and methods, and how to evaluate results and interpretations.
ObjectiveAfter attending this course, you will be able to:
1. Use your understanding of plant ecological theory to interpret primary data (tables, graphs) from ecological studies.
2. Critically evaluate evidence and conclusions presented in ecological studies based on your understanding of plant ecological processes.
3. Apply your knowledge of plant ecology to make general predictions about major responses of plant communities to biotic and environmental perturbations.
4. Evaluate the main methodological approaches used to study ecological processes in plants, and decide when they should be applied to address a research question.
ContentPlant communities can be spectacularly diverse, which has long puzzled ecologists since all plants compete for the same few limiting resources. Plants also represent the matrix of ecological communities, and the structure and dynamics of plant populations drives the functioning of terrestrial ecosystems. This course provides insight into these broad themes by providing an introduction to the essential ecological processes involved with plant life. We use original research examples to discuss how ecological questions are studied and how results are interpreted. Specific topics include:

- Plant functional traits (e.g. leaf economics, phenology), and how they determine interactions between plants and their physical environment.
- Plant life-history, and the different ecological strategies plants have developed to grow, survive and reproduce.
- Intra- and interspecific competition as regulators of plant population dynamics and multispecies coexistence.
- Interactions between plants and their friends (e.g. symbiotic fungi, pollinators) and enemies (e.g. herbivores, pathogens) above- and below-ground.
- Plant functional types and rules in the assembly of plant communities.
Lecture notesHandouts and further reading will be available electronically through the course Moodle at the beginning of the semester.
Prerequisites / NoticePrerequisites
- General knowledge of plant biology
- Basic knowledge of plant sytematics
- General ecological concepts
701-1410-01LQuantitative Approaches to Plant Population and Community Ecology2 credits2VJ.  Alexander, T. Walker
AbstractThis course presents leading problems in plant population, community and ecosystem ecology and modern tools to address them. Topics include parameterising models of plant population dynamics, using biological networks to investigate species coexistence, exploring the physiological and functional basis of plant life history strategies and quantifying how plants influence ecosystem functioning.
ObjectiveStudents will attain deep insight into topics at the cutting edge of plant ecological research, whilst developing specific skills that can later be applied to basic and applied ecological problems.

AbstractThe organization and functioning of academic research as well as academic publishing are introduced and applied: students critically review two term papers written by their student colleagues. Based on the reviews, the authors of the papers write reply letters and revise their own term papers. They finally present their topic during an in-house "mini-conference" with a talk.
Objective• Students become familiar with the academic peer-review and publishing process
• They learn to evaluate the quality of a manuscript and formulate constructive criticism
• They learn to deal with criticism of their own work (by their student peers)
• They practise oral presentations and discussions in English
