Anotace
The course aims to enable students to understand the fundamental roles of plants in the context of the functioning of different ecosystems, biomes and the entire planet Earth. The course will give students an idea of the interaction of plants with their environment - abiotic and biotic factors, how plants respond to environmental factors and stress conditions, how the physiological functions of plants in ecosystems determine ecosystem functioning and what are the roles of plants in global processes, biogeochemical cycles, climate formation. In addition to physiological functions, different adaptations of plants to different environments will be discussed, whether adaptive, evolutionary, or acclimative within the plasticity of plant responses to environmental factors. Due to the interconnectedness of climate and vegetation, the interpretation will focus not only on the effects of climate on plants, but also on the impact of local, regional and global climate by plants. The lecture will also address the ongoing climate change and its impact on plants and how plants affect the planet's climate. Attention will also be paid to the interaction of plants with other organisms in ecosystems - plants, soil microorganisms. Attention will also be paid to plant monitoring using functional traits. Plant monitoring will be demonstrated primarily on functional features of plants, biochemical and biophysical indicators of physiological status and using spectral methods, especially reflectance.
The course is composed of lectures only and is lectured together with the course MB130P09 Plant Ecophysiology, which has in addition also practical training nad, thus, more credits.
