We are pleased to announce our forthcoming workshop on Structural Equation Modeling (SEM), scheduled to take place from April 8th to 10th, 2024, from 10 am – 1 pm PT / 1 pm – 4 pm ET. This course offers a comprehensive exploration of SEM, delving into its theoretical underpinnings and practical applications. Participants will gain a profound understanding of causal modelling, latent variables, and the nuances of covariance-based and Partial Least Squares (PLS) SEM methodologies. Through in-depth instruction, attendees will learn to leverage prominent software tools to conduct sophisticated analyses of complex datasets. Covering conventions, terminology, model specification, and evaluation, this course equips professionals and researchers with the essential skills to navigate SEM effectively.
The training will be conducted by our fellow Varina Crisfield, an awarded PhD candidate in Key Biodiversity Areas at the Université de Sherbrooke. The workshop will be hosted virtually, and access information will be sent out to registered participants one day before the event.

New Year, new project! In February, BIOS2 will offer two workshops to help you get started with your data projects: Project Set-Up and Data Wrangling. In a mix of best practices tips, tutorials and hand-holding activities, these very basic workshops are designed to make you think about your project and data organization before you start anything, but also to help you reshape your current ongoing projects to something more organized and reproducible. Registrations are open until two days before of the first day of each workshop, and seats are limited (max. 40 people each).
These workshops should be accessible to any graduate student, though prior experience in R is helpful. The workshop will be in English, with support in French, and it will be presented online. The link to access it will be communicated shortly before the workshop.
Learn and practice project organization, reproducibility tips, project maintenance, and more! Instructors: Andrew MacDonald and Gracielle Higino When: February 5, 6 and 7 @ 11 am PT / 2 pm ET Where: online
Learn the best practices on data tidying and follow along a tutorial on OpenRefine. Instructors: Simran Bains, Lukas Van Riel and Timothée Poisot When: February 13 and 15 @ 10 am PT / 1 pm ET Where: online
When it comes to designing a statistical model, a lot of uncertainty comes to mind. In December, BIOS2 will offer a workshop which will give you some helpful strategies for fitting and understanding your regression models. Led by Dr Andrew MacDonald, the workshop will happen during 3h in two days on December 12 and 14, 2023, with lots of time for questions and discussions of your own work. This workshop should be accessible to any graduate student, though prior experience in R is helpful. The workshop will be in English, with support in French.
To register, fill out the form linked at the end of this page by December 9th, 2023.
What’s zero? When and how to center a variable?
What are the units? Scaling a variable and why you should do it.
What does it mean? Making predictions.
Does it depend? Fitting and visualizing interactions.
What do you expect? Simulating datasets.
The secret weapon: fitting the same model multiple times.
When: 13h EST, Tuesday 12 Dec and Thursday 14 Dec, 2023.
Duration: 3h each day (total of 6 hours)
Where: Online - information to be sent one day before the workshop
Registration deadline: December 9th, 2023
Machine Learning is not a black box (unless we want to!). If you ever wondered what the results of a species distribution model actually mean, BIOS² is here to help you! On October 6, 2023, at 1pm – 3pm EDT, Professor Timothée Poisot will host a short and very participatory workshop on how to interpret machine learning models applied to SDMs.
In this workshop, participants will build a simple model to predict the distribution of the raccoon in the South of Québec based on observations. Rather than focus on “what is the prediction?”, we will ask questions about “why”. Specifically, by mixing the presentation of the results with mini group discussions, we will question how the model works, when it is acceptable to apply our best judgment and ignore some performance metrics, and how we can think about interpretable machine learning to improve model transparency. Attendees will get access to all the code and data at the end of the workshop.
The workshop will be hosted virtually, and information about access will be sent out to registered participants one day before the event.
The BIOS² training program offers an Introductory workshop to Python for R users. The workshop will be presented on May 15 and 16, 2023 by Vincent Beauregard, data specialist at Biodiversité Québec.
The course aims to provide the basics of Python and to familiarize participants with the tools and libraries relevant to computational ecology. Sessions will build on participants’ prior knowledge of the R language to facilitate learning. Topics will include data manipulation with Pandas, data visualization with Matplotlib, and data analysis with Numpy and Scipy. Students will also learn how to break their code into functions and work with classes in Python.
Vincent Beauregard is a technical coordinator, and a specialist in infrastructure, biodiversity data interfaces and spatial data from remote sensing at Biodiversité Québec. He is interested in the automation of data processing schemes.
What: Introductory workshop to Python When: May 15 and 16, 2023 @ 1 pm – 4 pm (your time here) Where: Online and at Université Laval Language: English (bilingual Q&A and discussion) Fees: free – offered only for participants of the Advanced Field School in Computational Ecology. Registration deadline: May 11, 2023 Registration link: https://forms.office.com/r/kWvCrdpbus
The BIOS² and Hydro-Québec have partnered up to offer a workshop on environmental impact assessment on May 4, 2023 at 1 pm EDT. This workshop is free and open to all and is part of the training offered to BIOS² fellows.
This session will be a guided tour of Hydro-Québec’s perspective on biologists’ involvement in major hydroelectric projects. The main milestones of the environmental impact assessment process will be illustrated using multiple examples of projects that favoured biodiversity and were inspired by the field of applied ecology.
This workshop is the first activity of a series that will be done in collaboration with Hydro-Québec. In the fall, BIOS2 will be organizing a working group whose objective will be to propose solutions for better integration of ecological knowledge and biodiversity data into Hydro-Quebec’s environmental impact studies. The working group will be carried out in consultation with relevant stakeholders and in collaboration with biologists working at Hydro-Quebec. Trainees who are interested in participating in this working group are strongly encouraged to attend the proposed workshop on May 4.
