List of courses

Refresher courses (Biology, Computer Science and Mathematics)

These refresher courses are optional, but highly recommended so as to ensure that participants have the prerequisites necessary to follow the obligatory modules. During the second week there will be a conference intended for all EvoGEM participants (Sorbonne University Campus – see Bio0 for more information).

General schedule

There is some overlap between the refresher courses. Below is the global schedule of the two weeks dedicated to these courses:

Stochastic Models in Ecology and Evolution (MAEE)

Course coordinators

Stéphane ROBIN (stephane.robin@sorbonne-universite.fr), Gabriel LANG (gabriel.lang@agroparistech.fr)

Goals

At the end of the module, the student will be able to:

  • Define classical probabilistic dynamical models (random walks, birth-and-death processes, coalescent, Brownian motion);
  • Deduce Markov chain characteristics (ergodicity, stationarity, periodicity) in discrete time and space from its transition law;
  • Numerically implement a simulation code (exact or approximate) of a Markov process to study its properties empirically;

Contents

Introduction to classical probabilistic dynamic models in ecology and evolution, i.e. Markov processes:

  • in discrete time and space (Markov chains);
  • in continuous time and discrete space (Poisson processes, birth and death);
  • in discrete time and continuous space (Gaussian random walk);
  • in discrete time and continuous space (Brownian motion and stochastic differential equations);

Prerequisites

A student enrolling in the course should know:

  • what a matrix is and the elementary operations that apply to it (multiplication, diagonalization, inversion);
  • what a discrete and continuous random variable is, and the related concepts (law, density, distribution function, expectation, variance);

Knowledge of deterministic models of evolution, notably based on ordinary differential equations, is a plus.
For those who are interested in the course but for whom these notions are unknown or remote, don’t panic: you can acquire this knowledge by first taking the Math0 module.

Location

This module will be given at the Sorbonne Université, Campus Pierre et Marie Curie, 4 place Jussieu Paris 5ème. The exact rooms are given in the schedule below.
So as to understand where each room is situated, use the following example: Room 14.24.203 is located in the corridor connecting tower 14 and tower 24, on the 2nd floor.

Genomes Populations Species (GPS)

Course coordinators

Guillaume Achaz (guillaume.achaz@mnhn.fr), Pierre Gérard (pierre.gerard@agroparistech.fr)

Goals

This course will address the fundamental processes that are at work in evolution through the lens of molecular evolution and population genetics. It will devote time to statistical inferences based on the patterns of polymorphisms in sequence data. The intended participants are students motivated by the understanding of evolutionary processes and not entirely reluctant to theoretical models.

Themes

Wright-Fisher model in prospective (drift) and retrospective (coalescence)
Mode of crossing (panmixing, consanguinity, self-fertilisation)
Mutations and molecular diversity (nucleotide diversity, frequency spectrum, neutrality tests)
Recombination and demography
Structuring, Isolation and Speciation (migration)
Natural selection (in haploids and diploids)
Selection-drive-mutation interaction (in finite populations)
Molecular Clock and Phylogeny
The complex notion of “Effective Size”

Prerequisites

Biology/genetics & mathematics fundamentals.

Location

The whole module will take place at the Ecole Normale Supérieure (46, rue d’Ulm Paris 05) in room 321. Wednesday mornings are reserved for the MMAGE module, which will deal with two mathematical results related to the module (Ewens’ sampling formula and Diffusion) taught by Amaury Lambert.

Schedule

This module spans two weeks, but will be interrupted by one week of vacation. Week 1 will be October 2-6 and week 2 October 16-20, 2023.

Assessment

Home report on a particular concept in evolutionary genetics (1-2 months delay for writing after the end of the teaching unit)

Quantitative genetics (QG)

Course coordinators

Henrique Teotonio (teotonio@bio.ens.psl.eu), Diala Abu Awad (diala.abu-awad@universite-paris-saclay.fr) and Pierre de Villemereuil (pierre.devillemereuil@ephe.psl.eu)

Goals

The course will build on the biological, mathematical and genetic foundations of quantitative genetics (the study of the genetics of complex traits, coded by a large number of genes) to lead to a thorough and advanced study of the field. Students will learn the basics of quantitative genetic models and the partitioning of phenotypic variance (notably the notion of heritability), as well as the statistical study of these variance components on the one hand (animal models), and of selection and response to selection on the other hand (Price-Robertson identity). The course will cover a number of more advanced topics, such as genomic selection, genome-wide association, multivariate evolution (G-matrix, M-matrix, adaptive landscape). Finally, the course will present the modern uses of quantitative genetic tools to interpret experimental evolutionary results and the empirical study of adaptation in natural populations, especially with respect to global changes. A large part of the second week will be devoted to mathematical and computer modelling of the evolution of quantitative traits with the help of tutored projects.

Themes

  • Quantitative genetics, heritability, relatedness,
  • Components of genetic and phenotypic variance, animal model, selection gradients and intensity, response to selection,
  • G matrix, M matrix,
  • Genomic selection, genome-wide association, experimental selection, natural population.

Prerequisites

To be able to follow this course, there must be a basic understanding of population genetics. Familiarity with R, Python, and general ease with computer programs is highly recommended.

Location

The courses will take place on the campus of the University Paris-Saclay at the Institut Diversité, Ecologie, Evolution du Vivant:

IDEEV, 12 Route 128, Gif-sur-Yvette
B. McClintock room (Groundfloor)
How to get here:
RER B to Massy-Palaiseau then Bus 91.06 – bus stop Jolio-Curie
RER B to Le Guichet then Bus 09 – bus stop Jolio-Curie

Schedule

This module lasts two weeks and will take place from the 13th to the 24th of November 2023

Assessment

The students will be divided into groups of two to do the “Simulating phenotypic evolution” project which will then be presented with supporting slides to the faculty and other students, for 15-20 min at the end of the semester. This presentation will account for 40% of the final grade. 40% of the final grade will be based on written answers to questions that will be given to the students in the last day of the course. Students are expected to send their answers to H. Teotónio (teotonio@bio.ens.psl.edu) before the end of the semester (date to be decided). The remaining 20% of the final grade will be based on discussions during the Journal Clubs.
