Science Communication
Oral presentations, workshops, conferences and symposiums
Presentations I have given or am about to give, and workshops, conferences and symposiums I have organised or taken part in during my academic career, most recent first. Slides, posters and course materials are shared openly whenever I am free to do so.
Presentation: Regime Shifts in Plankton Dynamics: What Drives Them and Can We Predict Them?
Talk at the Ecomeets at Eawag series on abrupt changes in lake plankton communities, based on four decades of monthly monitoring of Lake Constance within the SeeWandel-Klima project.
Since this presentation contains sensitive data that are under a disclosure agreement, please write me an email to get open access to it.
Presentation: The Beaver as an Ecosystem Engineer – Effects on Water Quality and Freshwater Ecosystems
See the programme and register by 15 October (page in German).
Presentation: AQUASCOPE: Integrating high resolution monitoring and trait-based modelling to understand and predict phytoplankton dynamics
Talk at the FOREMA StatisticsLab Colloquium “Understanding Change Between Observations”.
Poster: Propagation and predictability of regime shifts in lakes
Poster presenting the SeeWandel-Klima project’s central question — can we detect, explain, and predict abrupt shifts in lake plankton communities? — using four decades of monthly monitoring on Lake Constance. With Luis J. Gilarranz, Stefanie Eyring, Stephan B. Munch, Tanya L. Rogers and Francesco Pomati.
Workshop: Advanced time series analysis using empirical dynamic modelling (EDM)
A three-day workshop I co-organised, bringing together participants interested in detecting causal relationships between variables without assuming a fixed model structure, and in forecasting how populations, communities and interactions respond to change over time. Participants were expected to arrive with a basic familiarity with dynamical systems, nonparametric regression, multivariable calculus and linear algebra.
Dr. Steve Munch and Dr. Tanya Rogers (NOAA Fisheries and University of California, Santa Cruz) were invited to give the workshop.
Organised jointly by the Pomati lab and the Machine Learning & Complex Systems group of Marco Baity-Jesi at Eawag, with the support and funding of the Biodiversity Center WSL–Eawag.
If you are interested in the course materials, please send me an email and I would be happy to share them under specific disclosure agreement.
Flash talk: Microbial plankton uptake enhances the degradation of a biodegradable microplastic
Main results on how marine microbial plankton interact with PLGA (poly lactic-co-glycolic acid), a biodegradable microplastic: to what extent and in which size ranges ciliate and nanoflagellate communities take the particles up, and whether their grazing accelerates the polymer’s degradation in seawater. Work carried out under the AQUACOSM-plus umbrella, in collaboration with Dr. Luca Schenone and Ulises Lora.
Published as Schenone et al. 2025, Microbial plankton uptake enhances the degradation of a biodegradable microplastic (Environmental Pollution) — code and data on Zenodo.
Presentation: Beavers influence stream dissolved organic carbon by coupling terrestrial–aquatic ecosystems
Talk on whether beaver ponds act as a source or a sink of dissolved organic carbon in Swiss streams, based on 16 sites sampled in 2021–2022. I present the causal hypothesis as a directed acyclic graph, the upstream–downstream sampling design behind the delta-DOC outcome, and the roles of aquatic primary production, terrestrial inputs, and pond age.
Guest lecture: Aquecimento do mar e o Atol das Rocas
Guest lecture on how ocean warming and marine heatwaves affect the food web of the Rocas Atoll, covering the thermal niches of the species involved, the long-term monitoring behind the work (PELD ILOC), and the modelling results and methods.
The presentation is in Portuguese.
