Prerequisites

There are no official prerequisites, but it is assumed that the student has previously acquired enough solid knowledge on subjects like: Biostatistics, Botany, Zoology, Extension of Zoology and Genetics

Objectives

This is a general subject that introduces the student to concepts and basic methodologies of Ecology. The subject also includes an approach to most current topics around this science.

This subject provides the basic contents and methodologies for the study of the structure and dynamics of natural systems in three basic levels of organization:

   1. Populations: studding the concept of population and introducing students in techniques of sampling abundance of organisms, in demography ecology and in population dynamics.
   2. Communities: teaching the student to evaluate the structure of the communities, the interactions between species and their manifestations at community level (food webs)
    3. Ecosystems: Introducing the student in the exchange of matter and energy in food webs, as a preliminary step to the study of biogeochemical cycles wihich will be studied mainly in the Biosphere Sciences subject

The training activities are organized into three main blocks: theoretical expository classes, seminars on various topics of ecology prepared by the students themselves and practices.

Theoretical classes

The theoretical classes are developed through expository master classes by the professors. To follow the classes the student will have a complementary material that will facilitate the monitoring of the class. This material will be previously available in the moddle classroom of the subject. Interposed between the theoretical classes, which will be organized approximately in three blocks, there are between three and five theory sessions where the students discuss with the teacher the answer of a series of short questions about the content given in the expository classes and that the students have previously available.

Debate sessions

At the beginning of the course a series of discussion topics on ecology issues are proposed that can be discussed from 2 points of view. The students are organized in groups and each group is assigned a topic and one of the possible approaches. Each group must document and try to argue the convenience of their approach or point of view on the subject. The result is shown in an oral presentation to classmates and the teacher where the students of the group must defend their point of view in contrast to the other point.

Practices

The practices are carried out in a group and consist of a field trip of a whole day in which data is collected directly in the field by the students. From thedata taken by the students themselves, a small work must be done in the format of a scientific article. In order to make data processing, students will also have a computer practice session with the teacher.

 

 

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
Presentation of the debate session 15 1 0.04 CM25, CM26
Partial or final exams 60 6 0.24 CM26, KM41, KM42
Written document about a debate session of another group 5 0 0 CM25
Practices document 20 0 0 SM39, SM40

The evaluation will be done in three blocks: the theoretical part, the debate sessions and the practices.

Theoretical part (60% of the final grade, individual grade)

A first partial written exam approximately midway through the semester. Represents 30% of the final qualification.

A second partial written exam at the end of the theoretical part. Represents 30% of the final qualification.

In case the joint note of the two partial exams is equal to or greater than 4 out of 10, the average can be calculated for the overall score. If the mark of the two partials does not reach 4, it will be necessary to go necessarily to the final exam if the student wants to pass the subject.

Final exam, an exam that includes the contents examined in the two partials (60% of the final qualification). This exam can be done by all students who want to improve their qualification. In the case that students who have passed the partial exams but want to improve the note are presented, they should not renounce to the partial marks so that they will always be average with the highest mark, either partials or this final exam. To be able to make average with the rest of the qualifications, the student has to reach a minimum of 4 out of 10 for this final exam.

Debate sessions (20% of the final grade)

The evaluation of this content consists of two parts: an oral presentation to the classmates and the teacher where the groups must defend their point of view (15% of final qualification, individual note) and a written text explaining the main arguments and justifying the degree of rigor of the two positions of one of the other debates (5% of the final qualification, group qualification).

Practices (20% of the final qualification, groupqualification

The teacher assessment of the work in form of a scientiic article, the instruccions for its writting are provided by the teacher. Students who wish may submit a nev corrected version of this work, the grade will be reevaluted and can increase the qualifciaton to a mxim of three points more than previous version

To pass the global subject, a minimun of 4 out of 10 must be achieved in the practices qualification

General evaluation rules

Students must take a minimun of 5 points out of 10 to pass the course.

To participate in the recovery exam, students must have been previously evaluated in a set of avaluation activites which weight as minimum two thirds parts of the total grade of total subject.

The students will obtain the \"Not valuable\" qualification when the evaluation activiteis carried out have a weight lower tahn 67% in the final qualification

Attendance to the practical sessions and field trips is mandatory. The students will obtain the \"Not Valuable\" qualification when their absence is higher than 20% of the time of the scheduled sessions


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

Criteria for use of Artificial Intelligence in the written document

For this subject, the use of Artificial Intelligence (AI) technologies is permitted exclusively in support tasks, such as bibliographic or information searches, text correction or translations, or others at the discretion of the teaching staff.

The student must clearly identify which parts have been generated with this technology, specify the tools used and include a critical reflection on how these have influenced the process and the final result of the activity. The lack of transparency in the use of AI in this evaluable activity will be considered a lack of academic honesty and may lead to a partial or total penalty in the grade of the activity, or greater sanctions in serious cases.

Single assessment

Students who request asingle theory assessment will take both partial exams in one day, coinciding with the date of the second partial and the grade obtained will represent 60% of the final grade. If the grade is equal to or higher than 4 out of 10, the average can be used to calculate the overall grade. If the grade is lower than 4, it will be necessary to take the final exam. To be able to make an average with the rest of the grades, you must achieve at least a 4 out of 10 in this final exam.

In the case of practical work, as it is a group work and it is delivered on-line, no single evaluation mechanism can be applied.

In the case of the evaluation of the debate sessions, as it is a group oral presentation, no single evaluation mechanism can be applied.
