It's official: the University of Namur joins the Réseau d'Échanges et de Liaisons entre Institutions d'Enseignement Supérieur Francophones (RELIEF). It thus becomes the fourth partner in this network, alongside the Université du Québec à Trois-Rivières (UQTR), the Université Savoie Mont Blanc and the Haute École Spécialisée de Suisse Occidentale (HES-SO).

Microplastics (MPs) are now ubiquitous in aquatic ecosystems, where their bioavailability to organisms and potential entry into the food web raise serious environmental and public health concerns. Substantial progress has been made in understanding MP toxicity, and their hazardous potential is now widely acknowledged. However, MP toxicity studies remain complex, as multiple particle characteristics, such as size, shape, polymer type, and sorbed contaminants might influence both bioavailabilityTo bridge this gap, the present thesis adopted a dual, complementary approach: (i) characterizing the environmental occurrence and bioavailability of MPs, and (ii) assessing the ecological relevance of using environmentally derived MPs in in vivo toxicity experiments.Overall, this thesis provides insights into the reproductive and transgenerational effects of environmentally relevant MPs while underscoring the importance of considering particle-pollutant interactions. By combining in situ field data with in vivo laboratory experiments, it demonstrates that the use of environmentally derived MPs represents a more realistic and ecologically meaningful approach to hazard characterization. Further studies should be carried out in this same perspective to generate robust, exploitable data and contribute to establishing a comprehensive MP risk characterization.

South America is a subcontinent rich in natural and cultural resources. Between biodiversity preservation and development cooperation, UNamur maintains valuable partnerships to address the challenges of biodiversity loss and understand current socio-economic transformations.

Semantic change, i.e. the evolution of word meanings over time, offers crucial information about historical, cultural and linguistic processes. Language acts as a mirror of societal change, reflecting evolving values, norms and technological advances. Understanding how the meaning of words evolves enables us to trace these transformations and gain a deeper understanding of our distant and recent past.This seminar explores how computational methods are revolutionizing our ability to analyze semantic change in historical texts, addressing a major challenge in the field of digital humanities. While advanced computational methods enable us to analyze vast datasets and uncover previously inaccessible patterns, few natural language processing algorithms fully take into account the dynamic nature of language, particularly semantics, which is essential for research in the humanities. As AI systems develop to better understand the historical context and dynamics of language, human annotation and interpretation remain essential to capture the nuances of language and its cultural context.In this presentation, I will show how computational and human-centered approaches can be effectively combined to examine semantic change and its links to cultural and technological developments. I will present examples illustrating how semantic change can be analyzed across temporal, cultural and textual dimensions."Methods "seminarsThe Methods Seminar is a series of seminars organized at the University of Namur with the aim of fostering interdisciplinary collaboration and knowledge exchange.

A team of American researchers, with the help of Frédérik De Laender, professor in the Department of Biology at UNamur, has just published in the prestigious journal Nature. Their study describes how changing stream temperatures and human introductions of fish can alter river biodiversity in the USA.

ILEE combines a broad range of basic, applied and social science skills that focus on three key areas of study, including historical perspectives and extensive partnerships with the global South.

The availability of natural resources for future generations can only be ensured through prudent use.

Through a variety of chemical, biological and physical factors, humans are modifying ecosystems, often with negative results. Environmental changes, in turn, affect the dynamics of human populations.

For four billion years, life on earth has been evolving and transforming in response to environmental change, resulting in fluctuating biological diversity. Ecosystems provide humanity with a wide range of free services that must be managed responsibly.

Since arriving on Earth, man has begun to influence and modify his environment.
