Learning objectives
At the end of the training activity, the student should have acquired knowledge and skills related to the mechanisms that regulate the ecological processes at different levels of complexity (organism, population, community and ecosystem). The course also aims to provide the first rudiments to apply some methods and techniques of ecological investigation.
In particular, the student should be able to:
D1. Understanding and understanding the structure, and adaptations of the main groups of animals and plants, the fundamental functions of living beings and their interactions at increasing levels of complexity, the relationships between organisms and the environment and between organisms at different levels of organization biological, the emerging properties of populations, communities and ecosystems and the main issues related to environmental sustainability. (Knowledge and understanding).
D2. To use the specific language of the Ecology. To apply the basic mathematical, statistical and informatics methods for the analysis and processing of information, experimental data on biological systems and phenomena and apply the main techniques of ecological analysis (Applying knowledge and understanding)
D3. Being able to expose the results of biological / ecological studies even to an untrained public. (Communication skills)
D4. To evaluate and interpret experimental data. Critically use data from scientific literature. To evaluate the computational and experimental methodologies that allow the optimal resolution of a biological / ecological problems. Evaluate the teaching. (Making judgments)
D5. To link the different topics dealt with each other and with the basic and related disciplines. To update by consulting the scientific publications of Ecology. To attend seminars and training study days. Acquire a methodology of study that allows the continuation of university education. Reach the skills required for inclusion in professional activities at the end of the three-year course. (Learning skills)

Teaching methods
Frontal lessons with interacts with soliciting comments and questions from the students. During the exercises in the classroom the teacher requires individual or collective collaboration of students in the solution of the questions proposed.
Assessment methods and criteria
Learning objectives were verified by ongoing audits, in the form of questions put to the audience of students during the lesson and random testing of proper conduct of exercises. The final exam is written, within one week of the end of the course, or oral, by appointment, during the year.
The written test, two hours lasting, includes 25 open questions and 5 exercises. The final vote derives from the sum of the scores obtained for question (maximum 1 point) and for exercise (from 2 to 5 points). The results of examination are published on Esse3 within a week from the test. Students can view the exam by appointment with the teacher. The oral exam is at least 3 questions referred, at least one is the contextualization and carrying out an exercise. The final vote is defined as percentage of: correctness of foreground (50%), and reasoning (30%), communication skills and synthesis (10%), language property (10%).
