Obsah předmětu
Content of lectures Non-homeostatic biogenic elements, biochemical evolution & composition of biomolecules; growth rate hypothesis; homeostasis of producers, invertebrate consumers, and vertebrates; conservation of mass holds for each element; nutrient availability controls population growth & dynamics; nutrient use efficiencies determine (species) competitiveness; resources' imbalance controls nutrient regeneration rates; resource stoichiometry determines biotic interactions; stoichiometry determines structure of food webs and controls biodiversity; synthesis of production ecology and population ecology, integration of ecological stoichiometry and the metabolic theory of ecology. Each student will prepare an individual journal club, using a case study from current literature focused on ecological stoichiometry in his/her PhD topic.

Výstupy z učení
Ecological stoichiometry is a new concept that describes the biology of elements (C, N, P) from biomolecules to the biosphere. While a classical view in ecology is based on energetics, ecological stoichiometry unifies it with a complementary view based on matter. Following the law of conservation of matter, ecological stoichiometry is an essential advance in unifying ecology across levels of organisation. It examines fundamental chemical constrains of ecological phenomena such as growth, reproduction, competition, herbivory, symbiosis, energy flow in food webs, and organic matter sequestration. Understanding of the biochemical deployment of elements in organisms provides the key to making sense of both aquatic and terrestrial ecosystems.
