This 18th international course on "Wood Anatomy and Tree-Ring Ecology" will be held in Klosters, Switzerland.
Date: November 25th to December 1st, 2018
Teachers: Holger Gärtner, Fritz H. Schweingruber & Alan Crivellaro
The aim of the course is to submit basic theoretical information about the anatomy of woody plants and especially ecological wood anatomy.
This will be done by demonstrating "the reality" (anatomical features) on the base of more than 370 micro sections which are prepared for each participant.
A very important part of the course is the additional teaching of different anatomical preparation techniques.

You will find a lecture room equipped with 20 microscopes for theoretical lessons based on more than 370 micro slides, two microscopes equiped with cameras and computers, cell analysis software "Image J", a fully equipped laboratory with different types of microtomes (GSL1 and WSL-Lab-microtomes), and a set of chemicals.
The lecture room is equipped with a PowerPoint-projector. We also provide a new script for the course, presenting all micro sections discussed during the lessons.
Bring with you, if possible:
- interesting material: cores, discs
- very pointed tweezers (Pinzette)
- microscope slides (Objektträger), cover glasses (Deckgläser) and razor blades. (We will also provide some)
- you can bring your own computer

- Lectures are based on more than 370 prepared microscopic slides to be discussed during the lessons.
- Specific features are discussed using microscopes
Basic anatomical cell and tissue types
- Construction of different stem types: without secondary growth, succesive cambia, bilateral working cambia.
- Introduction to taxonomic wood and bark anatomy
- Seasonal growth: cell production, lignification
- Construction of twig, branch, stem and root
- Different growth forms as herbs, dwarf shrubs, shrubs, trees, liana, e.g., monocotyledones, dicotyledones: conifers, angiosperms
- Intra-annual tree-ring features.
- Influence of physiological disturbances to wood structure, e.g., in extreme cold and hot climates in deserts and cold timberlines, frost and drought events, extreme light shortage.
- Influence of defoliation by insects mistletoes and human activities
- Influence of mechanical stress e.g., by avalanches, rock fall, floods, erosion, animals, forestry.
Practicing anatomical techniques
- storing and preparation of material for microscopic inspectionhandling microtomes
- using different staining procedures
- making permanent microslides
- observation in different optical instruments
- microscopic photography
- There are several sliding microtomes, chemicals and microscopes available for each participant
- Discussion of specific technical and scientific problems.
You work on your own material. We also offer material showing characteristic features.
