"The overall objective is to strengthen students’ foundational knowledge of evolutionary biology by addressing both (i) macroevolutionary phenomena and the general methods used to analyze them, and (ii) microevolutionary processes, with an emphasis on the population genetics approach. This course unit aims both to provide a solid common foundation of knowledge in evolutionary biology and to illustrate the discipline’s applications to the students’ future fields of specialization. The course includes: 1) lectures on evolutionary concepts; 2) laboratory sessions in two main formats: 2a. sessions focused on the use of analytical tools (phylogenetics) and on the mathematical formalization of evolutionary processes (population genetics), as well as 2b: sessions structured around group work, allowing students—based on their academic background and career goals—to explore a specific topic in greater depth (a fundamental question or an application of evolutionary biology)."

The objective of this course unit is to provide the necessary foundation in statistics to follow the more advanced modules in the curriculum; it is therefore a general refresher course. Descriptive statistics are reviewed (quantiles, cumulative frequency polygons, sample-based estimators); simple tests are introduced; essential graphs for univariate and multivariate data are presented; and the general principles of statistical testing, hypothesis testing, the concept of the p-value, and Type I and Type II errors are covered. In lab sessions, students also receive training in the R environment.

The M1 individual internship lasts approximately three months and, depending on the student’s program track, must be completed in a research laboratory or a non-academic organization. It allows students to gain professional experience in the fields of biodiversity, evolution, or ecology. It may be carried out at a local, national, or international organization, on a topic approved by the faculty to ensure it aligns with the specific objectives of the student’s program.

Assessment: Preparation for the internship is a graded assignment based on a written document and a presentation of the internship proposal. The internship work is assessed during a public presentation before a panel, during which the content of the report and the quality of the student’s responses to the panel’s questions are evaluated. The student’s conduct and initiative during the internship are assessed by the internship supervisor.

Mediation (whether scientific or not) increasingly relies on digital tools for disseminating information, which make it possible to reach a wide audience very quickly. These tools are numerous and diverse, and it is difficult to provide a simple overview of them. Nevertheless, the vast majority of job and internship postings in the field of mediation require knowledge of how to use these digital mediation tools.

The course unit proposed here will therefore aim to introduce students pursuing a career in science communication to the main tools of digital communication and provide them with an introduction to using them. The course unit will also provide an opportunity to discuss the importance of citing sources for published data and verifying that data at a time when misinformation and even outright lies are becoming increasingly prevalent.

The first part of the course will take the form of tutorials and lab sessions designed to introduce students to the main digital tools used in science communication. Examples posted online by various science communication organizations will be analyzed to identify their strengths and weaknesses.

The second part of the course will focus on practical application. Students will be required to visit science communication organizations (whether temporary or permanent) and submit reports on their visits using digital science communication tools. In particular, one of the reports will focus on the scientific activities of the Biology and Ecology Department and will be posted on the department’s website.

A course designed to link theoretical ecology, its practical application, and regional challenges as perceived by stakeholders in society. Built around a format that combines theoretical lectures covering the fundamentals necessary for understanding on-the-ground issues (ecosystem dynamics, anthropogenic impacts, socio-ecosystem resilience, in situ conservation, etc.), this course unit includes several field components (each consisting of a preparatory tutorial and an “active” field trip). Visits to these areas will provide opportunities to meet stakeholders (managers, elected officials, nonprofit organizations, shepherds, etc.) whose perspectives help students understand how ecological issues shape their actions and, in turn, how those actions impact biodiversity, its dynamics, and its distribution.

How is biodiversity distributed across the Earth? What ecological, evolutionary, and historical factors determine these patterns of biodiversity distribution? What changes have human activities brought about in the global distribution of biodiversity? In this course unit, we will study the role of spatiotemporal variations in the environment on a global scale on the dynamics of biodiversity. In particular, we will examine the influence of long-term climate cycles on both past and present organism diversity. We will also address the impact of human activities and global changes on biodiversity on a global scale.

The objectives of this EU initiative are twofold. On the one hand, it aims to trace all the major milestones in the history of organisms on Earth since the planet’s formation. Thus, topics such as the origin of life, the colonization of the continents, the emergence of angiosperms, glacial and interglacial cycles, and the domestication of plants will be addressed. Second, the course aims to demonstrate how paleoecology is relevant to the modern world, whether through methodological advancements (geochemistry, optical microscopy, electron microscopy, X-ray microscopy, etc.), models for predicting climate change, ecosystem management in the context of global change, or developments in biotechnology.  The course will primarily consist of lecture-style sessions (TD), each led by a specialist in the relevant topic.

"The objective of this course is to strengthen students' foundations in ecology and/or evolution by encouraging them to identify a research topic and question(s), formulate well-reasoned and relevant hypotheses, and justify a strategy for collecting and analyzing data to test those hypotheses.

Summary of the learning unit:

- Supervised independent work: identifying a relevant scientific question; conducting a literature review to assess the state of the art and justify scientific hypotheses; proposing and justifying a methodological approach (materials and methods) to test the proposed hypotheses.

Topic types:

Topics may address any issue identified by the students (in groups of 3 or 4) and approved by the teaching staff, and may draw on various approaches to align with the learning objectives of the different programs. For example, students may propose a field sampling or experimental strategy, a meta-analysis of data from the literature, an analysis of sequences retrieved from GenBank, an analysis of occurrence data retrieved from GBIF, etc.

In all cases, projects must include a concrete data collection strategy—identified, justified, and described by the students in the “Materials and Methods” section required for the M1S2 course—along with a projected timeline for the project’s progress and a breakdown of the tasks each student will perform within each group as part of the project’s implementation during the M2S3 course. Projects must also be financially realistic and include a projected budget, and they must be capable of being completed within the time available during the M2S3 semester.

Assessment Procedures:

"The course is based on a problem-based learning approach; students are evaluated on their progress in developing their methodology (40% of the grade), as well as on their ability to present and defend their project during a final oral presentation (60% of the overall grade)."

The objective of this course unit is to facilitate the implementation of the projects defined as part of the M1S2 course unit.

Summary of the learning unit:

- Independent work supervised by student groups: readjustment of project objectives and methodology as needed; data collection; ecological and/or evolutionary analyses and interpretations in accordance with the tentative schedule established in M1S2; presentation of results at a joint symposium for the various tracks.

Assessment Procedures:

As with the M1 course, this course is based on a problem-based learning approach. Students are therefore assessed on an ongoing basis based on their progress in completing their project (40% of the grade), and then at the end of the semester on their ability to present and discuss their project results during an oral presentation at a general project presentation session (60% of the overall grade).

"Instruction takes the form of an interdisciplinary project (biology, ecology, geology) that combines fieldwork, literature reviews, meetings with professionals or subject matter experts, and science outreach. The goal is to produce a comprehensive scientific study of a specific region, linking the area’s bio-ecological and geological characteristics to its economic, social, historical, and/or cultural heritage features. Students work in small groups (usually 2; 3 at most), under the supervision of a tutor. They must produce a written thesis (in the style of a science outreach publication) and organize a one-day field session, which is tested with a group of students and faculty members."

The course takes the form of a project based primarily on a bibliographic approach. It involves a study of the epistemology and history of science focusing on the work of a scientist in the fields of Life Sciences or Earth and Space Sciences. Students must highlight the key aspects of the scientist’s work by situating them within the scientific, historical, and political context of their era, emphasizing the advances and controversies, contributions to science, and implications for science communication. Upon completion of this work, carried out under the supervision of an advisor, students will produce a written thesis, a poster, and an oral presentation.
