Prerequisites

The knowledge areas involved in this subject are Physiology, Cell Biology, Biochemistry and Molecular Biology, Genetics, Immunology and Zoology. It is convenient for the student to have a basic knowledge and competences on the structure, organization and function of organisms, as well as general concepts of ecology and evolution.

Objectives

The learning of Comparative Animal Physiology is necessarily systemic. The study of complex physiological processes, such as acclimatation to extreme environments or the acquisition of new behavioral patterns in response to selective pressures, should be evaluated through the interaction between different levels of organization: from the phenotypic expression of the genome to the functional responses of populations in a changing ecological context. This integrative approach is achieved through the exercise of biological analysis, once the students have assimilated the essential concepts for the physiological evaluation.

The subject Compared and Environmental Animal Physiology is programmed during the fourth year of the degree in Biology and increases the knowledge of the functioning of the organisms in relation to the environment and adaptations. The acquisition of the basic competences of this subject will complete the view that students have of the animal physiology throughout the previous courses, giving a global and integrated environmental vision, by means of the understanding and the study of the mechanisms that have been chosen evolutionarily in the different animal groups..

The general training objectives of the subject are:

  • To acquire a comprehensive and integrated view of the interrelations of the different physiological systems of the organism respect to the environment in which they live.
  • To integrate the knowledge of Physiology with those acquired in other basic subjects in order to achieve a global vision of the functioning of the animal body and the mechanisms that allow the colonization of different niches.
  • To apply all the physiology knowledge in deducing the consequences of pathological alterations of the organism, and of the changes in the ecosystems and the consequences that they may have in the life cycle of the organisms.
  • Acquire the practical skills needed to carry out functional studies.

Learning activities and methodology

Title Hours ECTS Learning outcomes
Master classes 58 2.32 11, 12, 13
Autonomous study 40 1.6 1, 2, 11, 12, 13
Laboratory course 12 0.48 1, 2, 11, 12, 13
Service-Learning 46 1.84 1, 5, 11, 12, 13

The methodology used in this subject to achieve the learning process is based on the work of the student based on the information that is make available to him. The teacher's task is to give him the information or tell him where he can get it and help him in the learning process. In order to achieve the objective, teaching is based on the following activities:

Master classes:

With these classes the student acquires the basic theoretical knowledge of the subject that he / she will have to complement with the individual study of the explained subjects

Practical classes:

Practices are reinforced, through experimentation in the laboratory, those aspects that in theoretical classes usually have a special difficulty. On the other hand, in practice, the student's critical spirit, his ability to observe and the skills of analysis and evaluation of problems in the experimentation in comparative physiology are stimulated.

The service learning experience (ApS) has the following objectives:

(1) to transfer, compare and contrast the acquired knowledge when studying the concepts and processes of physiology based on murine / human / clinical models to the rest of animals present in the natural environment;

(2) to discriminate and critically select the information obtained from primary sources (articles, monographs ...) and secondary (articles of generalist journals, dissemination blogs, audiovisuals ...), for the purpose of

(3) to integrate the genomic, phenotypic, ecological and evolutionary information in the different levels of physiological analysis that facilitate the global understanding of physiological processes, close (current interactions between different organisms) and last ones (evolutionary conditioning and emergence of adaptations specific in the different lineages), finally,

(4) to be able to communicate effectively the results of the learning, in a formal and non-formal field, identifying the quality criteria of the information that is provided.

Supervised activities will be carried out in which the student must apply the knowledge and reasoning studied from the theoretical classes, solving a specific problem or explaining the results of their analysis and finding information in the class a specific physiological topic.

Annotation: within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

Continuous assessment activities

Title Weight Hours ECTS Learning outcomes
Service-Learning 40% 5 0.2 1, 2, 3, 4, 5, 7, 8, 9, 11
Theory exams 50% 3 0.12 1, 6, 11, 12, 13
Lab course 10% 1 0.04 2, 7, 10, 11

Assessment of the theoretical part: the corresponding part of the subject will be assessed individually, the students who do not pass the partial exam can recover it in the final exam. This evaluation has a global weight of 50% of the final mark, the minimum mark to pass it 5. To participate in the recovery, the students must have previously been evaluated in a set of activities the weight of the which is equivalent to a minimum of two thirds of the total grade of the subject or module. Therefore, students will obtain the \"Non-Valuable\" qualification when the assessment activities carried out have a weighting of less than 67% in the final grade.

Evaluation of the lab course: the lab course is mandatory and will be evaluated by submitting a group report once the course has been completed. This evaluation has a weight of 10% of the final mark.

Evaluation of service learning (ApS): The pedagogical and technical materials developed will be evaluated, as well as their dissemination and interaction with the counterparts.This evaluation has a weight of 40% of the final mark.

The lab course and the active learning activities can not be recovered.

Not submitted: it will be considered that a student will obtain the qualification of not presented if at least 50% of the assessment activities are not presented.

Single assessment: in the case of those students who request a single assessment, the lab course is mandatory (delivery of a practice report) and accounts for 10% of the final mark, the theoretical exam will account for 50% of the final mark and the delivery of works/activities related to PBLs will account for 40% of the final mark. The same recovery system will be applied as for the continuous assessment. The review of the final qualification follows the same procedure as for the continuous assessment.


For this course, the use of Artificial Intelligence (AI) is permitted exclusively for support tasks, such as bibliographic or information searches, text correction, or translations. The student must clearly identify which parts have been generated using this technology, specify the tools used, and include a critical reflection on how these tools have influenced the process and the final outcome of the activity. Lack of transparency in the use of AI in this graded activity will be considered a breach of academic honesty and may result in a partial or total penalty in the grade for the activity, or more severe sanctions in serious cases.


Any irregularity committed during an assessment activity (academic misconduct, plagiarism, or improper use of AI, unless such use is expressly authorized in the course syllabus) that may lead to a significant alteration of the grade will result in that activity being graded as 0. If the course syllabus stipulates that obtaining a minimum mark in this assessment is an essential requirement to pass the course, or if multiple irregularities occur in the assessment activities of the same course, the final grade for the course will be 0. Furthermore, disciplinary proceedings may be initiated against any student who incurs any of these irregularities.
