Investigating river-sea system sediment connectivity: from Source to Sea

On a global scale, the flux of particles from rivers to the sea is estimated at 20 billion tonnes of sediments per year, with huge implications both from a geomorphological and ecological point of view. Indeed, though a natural component of all water bodies, the sediment itself is often considered a physical and chemical pollutant of water bodies. However, even if riverine transport is the primary direct impact of human activities on coastal environments, coastal management plans often lack systematic processes to assess land-based impacts. In such a context, the concept of the River-Sea continuum, which entails the assessment of sediment connectivity of the river basins and their deltaic systems, plays a fundamental role. Collecting sufficient data to quantitatively determine system connectivity is, however, extremely time and resource expensive. Satellite Earth Observation (EO) systems provide a powerful tool to define a holistic approach for efficient integrated coastal management plans. During this seminar, an overview of the main approaches employed for the assessment of River-Sea system sediment connectivity and the potential of the EO systems in this context will be presented.

Al largo dei Campi Flegrei una nuova caldera e una frana sottomarina

Uno studio di INGV e CNR-ISMAR ha individuato strutture geologiche sottomarine finora sconosciute a ovest dell’isola di Ischia. Intervistato Salvatore Passaro, ricercatore del Cnr-Ismar.

“Un’antica struttura vulcanica e un’ampia frana sommerse sono state individuate in Campania. Si trovano rispettivamente poco a ovest e a sud di Ischia e le hanno rilevate i ricercatori dell’Istituto Nazionale di Geofisica e Vulcanologia (Ingv) e dell’Istituto di Scienze Marine del Consiglio Nazionale delle Ricerche (Cnr-Ismar). Una scoperta che apre uno spaccato sulla storia evolutiva del settore marino prossimo alla più nota area vulcanica dei Campi Flegrei, sotto osservazione per i frequenti fenomeni di bradisismo <>”

Gian Marco Palamara, CNR-ISMAR-Roma
“Integrated Modelling for Integrative Ecology”

ABSTRACT: Ecology is a discipline with flexible boundaries, where characterizing species interactions and ecosystem responses often requires accounting for the complexity, nonlinearity, and stochastic nature of biological and environmental processes.
In this talk, I will present different ecological case studies combining experimental and theoretical approaches to explore population and community dynamics under environmental stress and spatial heterogeneity. In the first part of the talk, we analyse long-term experiments on Daphnia galeata exposed to sublethal pesticide concentrations using a stochastic, age-structured population model. Bayesian inference reveals significant treatment effects — particularly for the insecticide Diazinon — on mortality and fertility, with clone-specific responses reflecting potential adaptation. The model also accounts for strong demographic stochasticity, supporting more reliable interpretation of ecotoxicological data. In a second case study, we develop stochastic models for multi-species systems, including food webs and metacommunities. Using continuous-time Markov processes, we revisit functional response theory, predator prey equations, and finally explore biodiversity dynamics in dynamic landscapes modelled as time-varying random geometric graphs with neutral dynamics. Among other things, our findings show that fluctuating connectivity can enhance both local and regional species richness, offering new theoretical insights into spatiotemporal drivers of biodiversity.
Together, these studies demonstrate how stochastic models can reveal hidden mechanisms in ecological systems — from controlled experiments to complex landscapes.

Gian Marco Palamara was born in Rome and trained as a physicist. For over a decade, he has worked internationally at the intersection of theoretical ecology and ecological modelling, collaborating closely with empiricists to develop robust theoretical frameworks for understanding the drivers of biological diversity. More recently, Gian Marco has been exploring integrative approaches to ecology that bridge disciplinary boundaries, drawing together insights from the mathematical, natural, and social sciences.
