Lecture by Thierry DUTOIT, Ecologist and CNRS Research Director (IMBE) and Emma LEONE, PhD student in Ecology (IMBE)
On Wednesday 24 September at 7.00 pm, a conference will be held by Thierry Dutoit, Ecologist, CNRS Research Director at IMBE and Emma Leone, doctoral student in ecology at IMBE entitled
"Bad military memories in natural areas. How to clean up and renaturalise? ".
As always, this event will be accessible in person at the Endoume marine station in Marseille as well as live from 7pm:
Summary of the conference: The contamination of ecosystems by persistent substances from military munitions is a very worrying phenomenon, particularly as a result of the expansion of conflict zones around the world, but also in areas where there have been conflicts in the past or where there are military training, manufacturing or destruction sites for munitions.
This is particularly true of the Crau plain in the Bouches-du-Rhône region, a remarkable natural area that is now protected but has been heavily impacted by military activities since the end of the 19th century. Could nature-based solutions help to clean up and renaturalise this ecosystem while limiting the impact on its exceptional flora and fauna?
We look forward to seeing you in person or by videoconference!
Notice of defence of the thesis of Sabrina CESARIN, doctoral student in the Biological Engineering Department of the IUT of Avignon University
Sabrina defended her joint thesis with the University of the State of Sao Paulo (UNESP Brazil) on Thursday 4 September 2025.
This former doctoral student worked in the Biological Engineering department of the Avignon University IUT, where she carried out her work from October 2023 to September 2024.
New scientific evidence on the ineffectiveness and injustice of climate policies
Planting trees alone will not solve the problem of climate change, and there is no miracle solution for truly inclusive ecosystem restoration.
A new study, published on 31 July 2025 in the journal Nature Geoscienceshows that restoring our natural habitats can only offset a small proportion of the carbon we release into the atmosphere. It is therefore crucial to reduce emissions rapidly, while ensuring that restoration initiatives are equitable, focused on biodiversity and adaptation to climate change.

Emma Leone, a first-year PhD student in the EECAR team, wins a prize!
Emma Léonea doctoral student in the first year of her thesis in the EECAR to theUMR IMBE-IUT d'Avignon University won the prize for best oral paper at the de la French Society for Fundamental and Applied Ecotoxicology which took place in La Roche-Sur-Yon from 1 to 4 July 2025.
His paper looked at the very long-term effects of soil contamination following the burning of munitions in a protected natural area, the Crau plain in the Bouches-du-Rhône département.
Half of his research is supported by the Sud-PACA region via the "Emplois Jeunes Doctorants" scheme and the company RSK-France.
His work is also the fruit of collaboration between three UMR, LCE, LPED and IMBE and should lead to the implementation of operations to rehabilitate and ecologically restore polluted sites.
Our heartfelt congratulations go to Emma on winning this award for her first oral presentation at a conference!
A new biodiversity reserve: La Crau du Piboulon
Thanks in part to the work of Thierry Dutoit, director of research at CNRS at IMBE, La Crau du Piboulon, located between Alleins and Mallemort, has become the first biodiversity reserve in the Aix-Provence-Marseille Metropolitan Area.
Thierry and his colleagues (Hervé Ramone, Daniel Pavon, Elise Buisson, Anouk Courtial) discovered over 90 plant species in an area of 100 m², and counted a dozen orchid species, including Anacamptis coriophora subsp. fragransand two protected species, Serapias parviflora and Ophrys provincialis.
A fine example of how avoidance in advance is better than compensation and restoration in retrospect to conserve exceptional natural areas!
Ants: tiny and fascinating!

Léo ROCHER's thesis defence: Wednesday 10 April 2024 at 2:30 pm - amphitheatre of the Avignon University Institute of Technology (IUT)
After 3 years of work on the influence of grassing between vine rows on auxiliary arthropodswe are delighted to invite you to the thesis defence from Léo ROCHERentitled : "Identification of vegetation parameters favouring beneficial arthropods and associated ecological functions in viticulture: a correlative and experimental approach", which go to will take place on Wednesday 10 April at 2.30pm, within the IUT amphitheatre.
Summary of thesis:
The decline in biodiversity in agro-ecosystems is largely attributed to the rise of modern agriculture. The main causes are the destruction of semi-natural structures, the extension of the size of agricultural plots and the intensive use of inputs. Arthropods play an important role in enhancing essential ecosystem services such as pest regulation and pollination. Vegetation is a key factor in encouraging their presence. Plants provide crucial food resources and habitats for arthropods. To encourage these organisms in agro-ecosystems and restore the associated ecological functions, practices such as the introduction of semi-natural structures are relevant. In permanent crops such as vineyards, such structures can be set up within the plots. In the Mediterranean region, vineyard inter-row management often involves eliminating uncultivated vegetation for reasons of water competition and to control plant species considered harmful.
The aim of this thesis work is to gain a better understanding of how inter-row vegetation can encourage the presence of beneficial arthropods and the predation function, while limiting the proliferation of harmful plant species in Mediterranean vineyards (Luberon, France). Three main research questions were posed: (1) Does the presence of grass cover and its floristic composition influence the presence of ants, important players in the predation function in vines? (2) Which functional groups in the vegetation are linked to the abundance of predatory and pollinating arthropods and the predation function? (3) Does diversified and local grass cover increase the presence of beneficial arthropods, improve the predation function and limit the establishment of problem plant species?
In the first chapter we studied the response of ants to grass cover in 23 vineyards. Ants play a crucial role in predation in Mediterranean vineyards (Luberon, France). We tested the effect of three vegetation management methods on the diversity and frequency of ants: inter-row grassing, partial grassing and no grassing. We showed that the partially grassed vineyards had a greater diversity of ants than the non-grassed vineyards. Grass cover and the presence of perennial plants positively influenced ant richness, suggesting the importance of taking these factors into account in vegetation management. In the second chapter, we examined which characteristics of spontaneous vegetation influence beneficial arthropods and predation function in 37 vineyards. We found that nectariferous flower cover and plant species richness favoured most groups of beneficial arthropods, as well as the predation function. These results highlight the importance of floral resources and plant diversity in favouring the presence of the arthropods studied. Finally, the last chapter is devoted to a sowing experiment and its monitoring over two years. Three types of grassing were compared: high-diversity sowing, spontaneous vegetation and inter-rows without vegetation. In line with the second chapter, our results highlight the positive effects of plant richness and flower cover on weed control, the abundance of beneficial arthropods and the predation function. All the results of this thesis work converge and highlight the importance of considering different vegetation parameters to favour beneficial arthropods in viticulture.

lecture by Clémentine Mutillod entitled "Is the grass always greener elsewhere? The effects of the return of wild horses (Equus ferus przewalski) to the Mongolian steppe".
Thursday 11 April 2024, from 1pm to 2pm, as part of the Midisciences organised by Avignon Universityour colleague Clémentine Mutillod (IMBE doctoral student - IUT d'Avignon) will give a talk entitled "Is the grass always greener elsewhere? The effects of the return of wild horses (Equus ferus przewalski) on the Mongolian steppe".
"In 2004 and 2005, Przewalski's horses - considered to be the last wild horse in the world - were reintroduced into their original area, the steppes of Mongolia, in an enclosed reserve covering 14,000 ha. Following an initial monitoring of the flora inside and outside this reserve in 2010, a second field campaign was carried out in 2023, as part of the thesis of Clémentine Mutillod thanks to Avignon University, the Société Française d'Écologie et d'Évolution, the Khomyn Talyn Takhi association and the Takh Association.
A look back at the two months spent on site, between scientific surveys and natural and cultural discoveries.

The wild horses of the Causse Méjean at the service of biodiversity by Clémentine MUTILLOD
Article from the newspaper "la Marseillaise
Ecology researcher Clémentine MUTILLOD (IMBE IUT Avignon UNIVERSITY)
"... rewilding is nonetheless a complementary approach to ecological restoration".
GoodPlanetMagRestoring ecosystems or rewilding: what is the best approach for restoring an ecosystem disturbed by human activities?
The issue is the subject of much debate among scientists and environmentalists.
A recent study published in the journal Biological Conservation in February 2024 provides some answers.
In particular, the scientists compared the impact on grassland ecosystems in France. They compared the repercussions for the environment of the introduction of a wild herbivorous mammal, in this case Przewalski's horse with those of domesticated mammals such as sheep and horses.
In this interview, the doctoral student at IMBE (IUT Avignon) Clémentine Mutillod explains this research.
The IUT d'Avignon Université congratulates Clémentine Mutillod on this brilliant achievement.
