Plant Ecology

Description

Natural abiotic (climatic and edaphic), biotic and anthropogenic factors of the environment of plants: molecular, individual and community level. Phytoindication of pollution. Interaction of plants with physical and biological environment. Distribution and abundance of plants. Population ecology. Community ecology. Ecosystems, Plant diversity and conservation. Laboratory work includes examination of morphological-physiological adjustments of plants to surrounding environment.

Aim of the course

The aim of this course is to get acquainted with the problems of plant ecology, research methods, environmental diversity, plant change in space and time, human impact on plants.

Prerequisites

Knowledge in General Biology, Embryophyte anatomy, morphology and systematics
