Teaching description
basic knowledge of general physiology
The course analyzes the physiological responses of animals to the environmental variability. Moreover, it focuses the attention on the physiological responses to chemical pollution exposure and on their application in environmental biomonitoring
The objective of the course is to provide students the basic knowledge of the environmental physiology (physiological responses to the variability of the environmental factors), and to gain a sound background in the physiological responses of animals to environmental pollutants and in their application in the ecotoxicological monitoring.
Lectures (5 CFU, 40h) and practicals (1 CFU, 10 h)
The assessment ìs performed by oral examination. In particular, the examination consists of an oral presentation of 15 min (with a power point support) about one of arguments included in the first part of the course: omeostasis, acclimatization, osmoregulation, gas exchange, physiological responses to temperatue variations) followed by an oral test on the arguments included in the second part of the course (responses of the organisms to pollutiants).
The attribution of the final score will take into account: the level of theoretical and practical knowledge acquired (50%), the ability to apply the acquired knowledge (30%), autonomy of judgment (10%), of communication skills (10%).
