Plant Taxonomy and Biosistematics: taxonomic and biological species; infraspecific variability. Natural plant populations. Hybridization and recognition of hybrids . Origin of the species: gradual and abrupt speciation. Modern methods to study the natural populations: Morphological information; information from breeding systems; caryological and chemical information
Plant environment: Flora. Vegetation, Cartography.

Learning Objectives
Knolewdge acquired
How to study the plant biodiversity in the field (morphology, cariology, reproductive systems).Patterns of speciation. Identification of shrubs and trees.
Competence acquired:
Ability to point out the natural plant diversity and to place it in the taxonomic classification system.
Skills acquired (at the end of the course):
Capability to acknowledge the plant biodiversity in the field.
Capability to interpret the role of the plants in the ecosystems in function of their bio-ecological characters and the relations with the other species; capability to read a vegetation map.

Course program
Plant Taxonomy and Systematics. The species concepts: taxonomic and biological species. The natural populations and their variability: Hybrids and introgression.
Origin of the species: gradual and abrupt speciation.
Autogamic, heterogamic and apomictic wild plant populations.
Morphological, reproductive and caryological characters used in plant classification-
Chromosomal information; chromosome number and structure of the karyotype.
Chemical information: value of chemotaxonomy; secondary metabolites, proteins, DNA, RNA.
Flora: number of the Italian taxa, methods to make a “flora”. Regional and national floras
Plant communities in space and in time. Physiognomy and structure of the vegetation.
Plant communities and their interpretation; Phytosociology; sampling methods of plant communities; maps of flora and vegetation.
Identification of the most common shubs and trees of the Italian flora
