Bachelor's degree

This course is a cross-disciplinary course in L2 SV aimed at providing biology students with a fundamental knowledge base on plant functioning, enabling them to understand current issues in plant agricultural sciences.

The following basic concepts of Plant Physiology/Functional Biology will be studied: 

Essential experimental approaches: plant transgenesis, forward and reverse genetics

basics of autotrophy

mechanisms underlying the major stages of angiosperm development: meristem function, floral transition, fertilization.

auxin, a major hormone for plant development and their response to the abiotic environment

The practical sessions will enable students to manipulate the regulation of plant water nutrition and analyze their mineral nutrition using various biochemical assays (flame photometry, spectrophotometry).

Description of the EU (max. 10 lines):

The aim of this EU is to explain how to measure variation in biology and how it can be represented. It is based on concrete examples from various disciplines of biology (ecology, developmental biology, evolution, genetics, physiology) and provides the statistical tools to measure this variation and the graphical methods to represent it. The statistical concepts of sampling, inference, distribution, central tendency, dispersion, distribution function, parameters, confidence interval, and dependence between variables for different types of variables (binomial, discrete, continuous) are explained using tutorials based on biological problems.

Skills targeted by the EU (see skills reference framework):

- Descriptive analytical tools in biology, introduction to biostatistics through the analysis of biological patterns

This course brings together three complementary and fundamental disciplines of Earth sciences: sedimentology, tectonics, and cartography. The different types of sedimentary rocks will be taught in detail in order to interpret their formation context and associated processes. The subjects of ductile and brittle tectonics will also be addressed at different scales in order to establish their formation context, particularly in terms of stress regimes. Practical work on samples will be carried out in parallel to enable students to develop their observation and drawing skills and to make use of the rich collections available in the department. Finally, an introduction to reading and working with geological maps (diagrams, cross-sections) will be provided, applying the concepts of sedimentology and tectonics previously acquired. This course unit should enable students to define the broad outlines of the geological history of a given region.

The EU is interested in describing the morpho-anatomical characteristics of the major organizational plans of metazoans found in current and past faunas, as well as explaining their origin and the dynamics of their appearance. It is thus developing a vision of organisms based on paleontology and zoology. It will mainly address the origin of metazoans and the main divisions, namely diploblasts and triploblasts, as well as basic concepts relating to the positioning and phylogenetic relationships between taxa (mono- and paraphyly, evolutionary convergence, etc.). It is traditionally divided into lectures, tutorials that mainly aim to illustrate and support aspects related to the biodiversity of taxa, and practical work in sessions aimed at acquiring skills, particularly and necessarily in dissection.

EUobjectives: Comparative study of major physiological functions in animals in relation to their environment. Study of structures and functions at various levels of integration, from the organism to the molecule.

Models discussed: mammals compared with other vertebrate models (teleosts, etc.) and invertebrate models (insects, crustaceans, mollusks, etc.).

Description: This course unit will cover certain major physiological functions (respiration, nutrition, excretion, and water and mineral regulation) as well as the basics of immunology and regulatory systems (nervous system and chemical communication). In addition to lectures, students will work in groups on various topics proposed by the instructors. They will present the topics in the form of presentations and summarize the key points to remember in a written summary. Practical work and tutorials will also be offered to illustrate the lectures.

The EU extends an EU from L2 S3 focusing on describing the morpho-anatomical characteristics of the major organizational plans of metazoans found in current and past faunas, as well as explaining their origin and dynamics of appearance through the acquisition of skills in paleontology and zoology. In S4, it will mainly explore the major subdivisions within protostome organisms, namely lophotrochozoans (annelids, mollusks, brachiopods, etc.) and ecdysozoans (arthropods, nematodes, etc.), while highlighting their phylogenetic relationships and their socio-economic importance or impact. The course is traditionally divided into lectures and tutorials, which will mainly aim to illustrate and support aspects related to the biodiversity of taxa, and practical work in sessions aimed at acquiring skills, in particular and necessarily through the performance of certain dissections.

The aim of this course is to introduce the concepts and tools used to observe and describe minerals and magmatic and metamorphic rocks and to understand their formation. The course will begin with an introduction to the concepts of mineralogy (crystallography, crystal chemistry) and the tools needed to identify the minerals that make up magmatic and metamorphic rocks. You will then study the structure and nature of the mantle and the processes involved from the formation of magmas to the eruption of magmatic rocks: partial melting, crystallization, crustal assimilation, and magmatic mixing. You will learn to distinguish between different magmatic series based on their chemical compositions and physical properties. The link between eruptive processes, hazards, and volcanic risks will also be discussed. In the third part, we will introduce the main variables (pressure, temperature, time) and the different geodynamic contexts of metamorphism. We will look at the different metamorphic facies, the structures and textures of metamorphic rocks, and you will learn to recognize mineral reactions and interpret them in terms of metamorphic evolution.

The combined study of magmatic and metamorphic rocks will provide the basis for understanding issues related to the geodynamics of the Earth's interior, geochemical cycles, mineral resources, etc.

The objective of this EU is to understand evolutionary processes at both the micro- and macro-evolutionary scales.

Using examples, manipulations, and accessible modeling, the lessons will aim to present in a concrete and quantitative manner the effects of the four evolutionary forces operating at the individual and population levels (mutation, migration, selection, and drift). The integration of these microevolutionary processes on larger time scales (e.g., differentiation between lineages, speciation) will then be addressed. Finally, the course will include an introduction to phylogenetics tools (reading and constructing trees) for studying macroevolutionary events (diversification, extinction) and tracing changes in character states, in particular by integrating fossil data.

This is a general education course that will cover many current topics related to human health. This course will address a wide variety of topics in the form of 1.5-hour mini-seminars, using both a pragmatic and critical approach. The numerous speakers in this course will contribute their expertise on topics such as immunity, molecular biology, cancer, nutrition, diagnosis, vaccination, bioethics, ecology, neuroscience, emerging diseases, and current and future therapeutic treatments. Each lecture will not only aim to provide cutting-edge knowledge and engage in critical analysis of their subjects, but also to guide students in researching and filtering scientific information in order to combat misinformation. On the major challenges of human health in the 21st century, we will address the real issues, the false controversies, and the solutions we can bring to them.

In this course, students will learn about the links between an individual's genetic heritage and the development of their morphology, physiology, and lifestyle. We will focus on understanding the links between the information carried by the genome and the life cycle of the organism in question, including the cellular characteristics corresponding to the expression of genetic information. This data will be placed in an evolutionary context and will shed light on some major evolutionary transitions, particularly in metazoans.

This course is a natural continuation of the course "Description of Variability" presented in S3. Its objective is to provide the concepts and methods on which modern biostatistics are based, namely the quantification of randomness, which is a ubiquitous issue in the life sciences. This course will serve as an introduction to inferential statistics: parametric and non-parametric tests, linear regression, and analysis of variance. Particular attention will be paid to the conditions for applying these methods, as well as to the concepts of type I and II errors, power, replication, and confidence intervals. Each concept will be illustrated with analyses of real and diverse biological data, contributing to the biostatistical culture that is useful for developing critical thinking with regard to scientific results. Practical work using R will provide training in this reference language and the statistical tools implemented in it, as well as an understanding of what has been seen in class through the application of the methods presented.

The EU addresses the different groups of plants ("algae," "cryptogams," spermatophytes), specifying for each of them their phylogenetic position and nature (monophyletic or paraphyletic group), their origin, and their specific characteristics in terms of morphology, anatomy, reproduction, and ecology.

Four grades present the different groups of plants: Grade 4, diversity of "algae"; Grade 5, biological cycles of "algae"; Grade 6, "cryptogams"; Grade 7, spermatophytes.

Six tutorials cover cross-disciplinary concepts based on oral and written exercises: Tutorial 1, Biological Cycles; Tutorial 2, Endosymbiosis; Tutorial 3, Interactions; Tutorial 4, Adaptation; Tutorial 5, Polyploidy; Tutorial 6, Phylogeny.

Six practical sessions illustrate the concepts covered in lectures and tutorials using living material: PS1, "algae"1; PS2, "algae"2; PS3, "bryophytes"; PS4, "pteridophytes"; PS5, Gymnosperms, vegetative system; PS6, Gymnosperms, reproduction.
