Course objectives
Lichen biology and determination:
The aim is to obtain knowledge about the terrestial lichens, with the main focus on genus Cladonia.
TLC methods used to proof the acids will be also part of the lectures.
Lichen physiology:
To obtain knowledge of physiological processes in lichen thalli, with special regard to stress physiology in extreme conditions.
Learning outcomes
The students should be able:
- to understand the principles of lichem symbiosis and formation of lichen thallus;
- to determine specimens into the main groups of genus Cladonia following macroscopical and microscopical methods;
- to understand the physiological processes, which enable lichens to survive in unfavourable conditions;
- to explain their application in nature (based on case studies in selected regions).
Syllabus
  • Introduction to lichen biology, ecology and determination (A. Košuthová)
    1. Introduction, lichen symbiosis
    2. Terrestrial lichens in vegetation, impact of the ecological factors
    3. Red-fruited lichens of genus Cladonia, ecology, phylogeography, determination (tradional methods)
    4. Brown-fruited lichens of genus Cladonia, ecology, phylogeography, determination (tradional methods)
    5. Others modern genetical and chemical determination methods
    Half-day practice: sampling in campus surroundings and subsequent identification of lichens.

    Lichen physiology (J. Hájek)
    Lectures:
    1. Anatomic and morphological characteristics of lichens in relation to their habitats
    2. Mechanisms of lichen resistance to cold and freeze
    3. High temeprature effects on ecophysiological chracteristics of lichens
    4. Functional groups of lichens in relation to hydric characteristics of ecosystem
    5. Mechanisms of lichen resistance to desiccation: Scaling from subcellular to individual level
    6. Secondary metabolites in lichens
    Practice:
    1. Anatomical structure of lichens with fruticose and foliose thallus morphology
    2. Lichen sensitivity to low and sub zero temperature: Linear cooling method
    3. Thallus dehydration effect on primary photosynthetic processes 1: OJIP method
    4. Thallus dehydration effect on primary photosynthetic processes 2: Kautsky kinetics method
    5. Lichen sensitivity to controlled photoinhibition in hydrated state: Chlorophyll fluorescence imaging
    6. Spectral and optical properties of lichen thalli
