BIODIVERSITY AND FUNCTIONS OF THE ECOSYSTEM
Learning outcomes of the course unit
This part of the course provides updated informations on hypotheses and models concerning the effects of the Global Change on mountain ecosystems.
Learnings of geobotany and climatology are requested..
Course contents summary
POTENTIAL IMPACT OF CLIMATE CHANGE ON VEGETATION: THE EFFECTS ON MOUNTAIN ECOSYSTEMS
a) Mountain systems as “hot spots” of plant diversity
b) Present and predicted climate changes on the mountains of the world
c) Potential responses of plant species to increasing temperatures: -1) persistence in situ (adaptation mechanisms); - 2) migration; - 3) Population fragmentation and extinction.
d) Potential responses of plant species to increasing CO2.
e) Potential responses of plant to increasing concentration of trpospheric ozone.
f) Potential responses of vegetation: -1) ecotonal shifts; - 2) changements in the floristic assessments; - 3) structural modifications.
g) The GLORIA project
h) Soil eutrophication in the mountain ecosystems - 1) different responses of bryophytes and vascular plants; - 2) compositional and structural modifications.
