Course description

Teaching program is provisional and may be subject to changes

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 exercitations (1 CFU, 12 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%).

We inform you that at the moment and until new dispositions the exam will be online, following the instructions included in the DR 197/2020. Students are kindly requested to be registered on the Microsoft Teams platform, according to the indications published on the page https://www.unisalento.it/lezioni-online (Documentation: Guide to Microsoft Teams for the student).
