Course Description

This 2-day course covers concepts, methods, and tools (i.e. R code) that can be used to analyse ecological network data using (but not limited to) the R package IGRAPH.

The course will review concepts on network construction and representation as well as their analysis. We will cover data manipulation and graph formats to represent data as networks. Additionally, we will cover structural analytical techniques commonly used to interrogate networks across different fields of applications. Finally, we will cover mathematical modelling of population dynamics on networks, using ordinary differential equations (ODEs). We will use some real-world empirical datasets to motivate analyses, such as describing network-level and node-level properties. We will complement this with simulated data from numerical simulations performed using the population dynamic models. We will emphasise visualisation and reproducible workflows as well as good programming practices. The modules will consist of introductory lectures, guided computer coding, and participant exercises. The course is intended for intermediate users of R who are interested in ecology, particularly in the areas of network analysis across ecosystem types. You are welcome to use your own data sets.

What You’ll Learn

During the course will cover the following:

  • Fundamentals of network construction and analysis.
  • Network metrics.
  • Methods to organise data in network format and prepare for analysis.
  • Network-level structural properties such as modularity, degree distributions and nestedness, and how to calculate them.
  • Node-level structural properties such as degree and centrality measures, and how to calculate them.
  • Dynamical ecological modelling using population dynamical equations.

Course Format

Interactive Learning Format

Each day features a well-balanced combination of lectures and hands-on practical exercises, with dedicated time for discussing participants’ own data, time permitting.

Global Accessibility

All live sessions are recorded and made available on the same day, ensuring accessibility for participants across different time zones.

Collaborative Discussions

Open discussion sessions provide an opportunity for participants to explore specific research questions and engage with instructors and peers.

Comprehensive Course Materials

All code, datasets, and presentation slides used during the course will be shared with participants by the instructor.

Personalized Data Engagement

Participants are encouraged to bring their own data for discussion and practical application during the course.

Post-Course Support

Participants will receive continued support via email for 30 days following the course, along with on-demand access to session recordings for the same period.

Who Should Attend / Intended Audiences

This course is designed for ecologists who are interested in learning the fundamentals of network analysis as applied to ecological communities and species interactions. A basic background in computer coding is assumed, with familiarity in R recommended to support smooth progression through the material. Participants should have a foundational understanding of quantitative concepts, including basic statistical properties of datasets, summary statistics, data distributions, and basic algebraic operations. While not essential, familiarity with calculus and differential equations will be helpful for understanding more advanced topics covered in the latter parts of the course.

Equipment and Software requirements

A laptop or desktop computer with a functioning installation of R and RStudio is required. Both R and RStudio are free, open-source programs compatible with Windows, macOS, and Linux systems.

A working webcam is recommended to support interactive elements of the course. We encourage participants to keep their cameras on during live Zoom sessions to foster a more engaging and collaborative environment.

While not essential, using a large monitor—or ideally a dual-monitor setup—can significantly enhance your learning experience by allowing you to view course materials and work in R simultaneously.

 

All necessary R packages will be introduced and installed during the workshop. A comprehensive list of required packages will also be shared with participants ahead of the course to allow for optional pre-installation.

Dr. Miguel Lurgi

Miguel is a computational ecologist and Associate Professor at Swansea University, UK, where he leads the Computational Ecology Lab. His research focuses on the ecological and evolutionary processes shaping complex species interaction networks across spatial scales and ecosystem types. He is particularly interested in how global change drivers impact the structure and function of ecological networks, from microbial communities to large-scale food webs.

 

Miguel earned his PhD in Terrestrial Ecology from the Autonomous University of Barcelona in 2014, conducting his doctoral research jointly at the Marine Sciences Institute (ICM-CSIC) and the Centre for Ecological Research and Forestry Applications (CREAF). He completed postdoctoral research at the University of Adelaide (Australia) and the Theoretical and Experimental Ecology Station of the CNRS (France) before joining Swansea University in 2019.

 

Education & Career

  • PhD in Terrestrial Ecology, Autonomous University of Barcelona (2014)
  • Postdoctoral Researcher, University of Adelaide, Australia (2014–2016)
  • Postdoctoral Researcher, CNRS – Theoretical and Experimental Ecology Station, France (2016–2019)
  • Associate Professor and Head of the Computational Ecology Lab, Swansea University, UK (since 2019)

 

Research Focus

Miguel’s work centres on understanding the mechanisms that drive the assembly and stability of ecological communities. He combines empirical data on species distributions and interactions with theoretical models that incorporate ecological and evolutionary dynamics, aiming to predict large-scale biodiversity patterns and their responses to environmental change.

 

Current Projects

  • Modelling the impact of global change on food web dynamics
  • Exploring microbial community structure through network theory
  • Theoretical frameworks for ecological community assembly across gradients

 

Professional Consultancy

Miguel contributes expert insight on network modelling and biodiversity responses to global change, collaborating with international partners on conservation planning and ecosystem management projects.

 

Teaching & Skills

  • Teaches courses in computational ecology, ecological networks, and biodiversity modelling
  • Skilled in R, Python, and network modelling frameworks
  • Strong advocate for reproducibility, open data, and mechanistic ecological understanding

Testimonials

PRStats offers a great lineup of courses on statistical and analytical methods that are super relevant for ecologists and biologists. My lab and I have taken several of their courses—like Bayesian mixing models, time series analysis, and machine/deep learning—and we've found them very informative and directly useful for our work. I often recommend PRStats to my students and colleagues as a great way to brush up on or learn new R-based statistical skills.
