Lunch break

Practicing anatomical techniques, field work, excursions


Participants give short presentations about their research
Friday ~16:00-18:00
Participants present their micro sections in a special session
Saturday, 02. Dec


- 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.

Image analysis

Practical work:

Practicing anatomical techniques

- storing and preparation of material for microscopic inspection
- handling 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.
