751-3801-00LExperimental Design and Applied Statistics in Agroecosystem ScienceW3 credits2GA. Hund, W. Eugster, C. Grieder, R. Kölliker
AbstractDifferent experimental designs will be discussed and various statistical tools will be applied to research questions in agroecosystem sciences. Statistical methods range from simple analysis of variance to mixed-models and multivariate statistics. Surveys and manipulative field and laboratory experiments are addressed and students learn to analyse data using a hands-on approach.
Learning objectiveStudents will know various statistical analyses and their application to science problems in their study area as well as a wide range of experimental design options used in environmental and agricultural sciences. They will practice to use statistical software packages (R), understand pros and cons of various designs and statistics, and be able to statistically evaluate their own results as well as those of published studies.
ContentThe course program uses a learning-by-doing approach ("hands-on minds-on"). The topics are introduced as short lectures, but most of the work is done on the computer using different packages of R – a software for statistical computing and graphics. In addition to contact hours exercises must be finalized and handed in for grading. The credit points will be given based on successful assessments of selected exercises.

The tentative schedule contains the following topics:
Introduction to experimental design and applied statistics in R
Data handling and data exploration with tidyverse
Designs of field and growth chamber experiments theory
Design creation with DiGGer
Fitting linear mixed-effects models with lme4
Marginal means estimation and post-hoc tests with emmeans
Nonlinear regression fits
Statistical learning techniques
Principle component analysis, canonical correpondence analysis (CCA), cluster analysis
Random forest

This course does not provide the mathematical background that students are expected to bring along when signing up to this course. Alternatively, students can consider some aspects of this course as a first exposure to solutions in experimental design and applied statistics and then deepen their understanding in follow-up statistical courses.
Lecture notesHandouts will be available (in English)
LiteratureA selection of suggested additional literature, especially for German speaking students will be presented in the introductory lecture.
Prerequisites / NoticeThis course is based on the course Mathematik IV: Statistik, passed in the 2nd year and the Bachelor's course "Wissenschaftliche Datenauswertung und Datenpräsentation" (751-0441-00L)

751-6127-00LPractical Course in Microscopy of Functional Histology
Does not take place this semester.
W+3 credits6Pnot available
AbstractDie "Funktionelle Histologie" beschreibt die histologischen und zytologischen Strukturen mit ihren jeweiligen Aufgaben und Wechselwirkungen innerhalb ausgewählter Organsysteme. Die endokrinologisch relevanten Organe und deren Präparation werden am Beispiel des Rindes kennengelernt.
Learning objectiveGrundlagen der Histologie; Gewebedünnschnitte (Gefrier- und Paraffinschnitte) und deren Übersichtsfärbungen und Immunhistochemie; Fortgeschrittene Mikroskopie von Gewebedünnschnitten; Kritische Bewertung von Physiologie/Pathologie aufgrund morphologisch/histologischer Kriterien
ContentJeder/m Studierenden wird ein Organ zugeteilt, mit welchem sie/er sich intensiv theoretisch und praktisch auseinandersetzt. Anhand dieses Organes als rotem Faden, welches vom Schlachthof bereitgestellt und von den Studierenden selber seziert, eingebettet, geschnitten, gefärbt und mikroskopiert wird, werden die Lernziele erreicht.
Die theoretischen Grundlagen werden in der Vorbereitung zum Kurs selbstständig erarbeitet. Zur Vorbereitung dient ein ausführliches Skript über die Herstellung mikroskopischer Präparate, zu Übersichtsfärbungen und zu den Prinzipien der Immunohistologie sowie zu den mikroskopischen Techniken und originäre Literatur über die Funktion des Organs in Zusammenhang mit agrarwissenschaftlichem Kontext. Die Theorie wird im Kurs im Detail vertieft und diskutiert.
Im Praktikum werden das Erstellen von Gewebedünnschnitten (Kryo- und Paraffinschnitte) und das Mikroskopieren von gefärbten und ungefärbten Gewebeschnitten selbstständig durchgeführt. Die Techniken der Übersichtsfärbungen werden angewandt und durch den Nachweis spezifischer Proteine mittels Immunhistochemie ergänzt. Die Darstellung und Erkennung von Einzelstrukturen ermöglicht ein Verständnis für das jeweils übergeordnete endokrine System, in dessen Zusammenhang das Organ steht. Pathologische Veränderungen werden Präparationsartefakten gegenübergestellt und somit eine kritische Bewertung von Beurteilungen aufgrund morphologischer Kriterien vorgenommen.

Aktivitäten: 5 Tage Praktischer Kurs mit theoretischen Einheiten, Vorbereitung der theoretischen Grundlagen im Selbststudium im Vorfeld, eine mündliche Präsentation der erhaltenen Ergebnisse und eine schriftliche Zusammenfassung (Arbeitsbericht) nach Abschluss des Kurses.
Prerequisites / NoticeIn Form eines Vortrags werden den anderen TeilnehmerInnen das zugeteilte Organ bzw Gewebe bezüglich der Morphologie, Histologie und funktioneller Gesichtspunkte vorgestellt.
In der Nachbereitung zum Praktikum wird ein Bericht angefertigt, in dem die Vorgehensweise (Verfahrensprotokoll), die Befunde (Ergebnisprotokoll) und die kritische Auseinandersetzung mit den Inhalten des Praktikums (kritische Beurteilung) dokumentiert werden.

AbstractThis forum is a platform for the critical reflection of relevant topics of livestock in the frame of the world food system comprising issues from basic knowledge to acceptance in society. The exchange is operated by scientific writing and presentation.
Learning objectiveIn the Forum "Livestock in the World Food System", a topic of significance for livestock agriculture is selected by the students and subsequently dealt with from various angles (from scientific basis to production systems, environmental aspects and to the acceptance by society). The students learn to present a scientific subject in writing and orally to an audience and to defend the presentation in a discussion.
ContentThe Forum "Livestock in the World Food System" will take place in blocks of 2 hours each. Once the general topic has been selected, it comprises two elements:

Element 1. Oral presentation: The students form small groups and are lecturers. There are chair persons (moderators) from outside of these small groups and they also head the discussion. The remaining students and lecturer are the audience.

Element 2. Scientific writing:
1. preparation of a short scientific type of paper from a result table offered by the lecturers
2. writing of a critical review of a chosen topic.

There will be a discussion in small groups at several choosable dates.

Introductions to both forms of presentation will be offered by the lecturer.
The preparation of the oral and written presentations takes place to a small part during the 2-h blocks and mainly outside of this time.
