Sim-MANA: A Learning Game to Promote Integrated Flood Risk Management Using Nature-based Solutions
No full textInternational audienceBackground Recent research (projects, articles, etc.) has demonstrated the interest of Nature-based Solutions (NbS), which aim at harmonizing flood management and sustainable development. However, their practical implementation is confronted by different obstacles, in particular the lack of knowledge about these measures and their efficiency for flood management. Intervention To meet this need, we have developed a learning game entitled ‘Sim-MANA’, an assessment protocol and a workshop-building approach. The assessment protocol was implemented in five workshops with various groups, including local authority teams, the general public, and territorial administrators. Methods Sim-MANA combines a role-playing game, a computerized simulation based on an Agent based-model and a physical interface (a 3D model of the territory). The game is designed for groups of between 5 and 25 players, who assume the roles of local stakeholders and citizens (for example, members of the municipal team, the watershed syndicate, local businesses and contractors, and so on). In order to evaluate the efficacy of the tool in facilitating learning, a series of pre- and post-questionnaires, an in-game observation grid, associated with a debriefing protocol have been developed. Results In the period spanning 2023 and 2024, five distinct gaming sessions were conducted and subsequently evaluated. The workshop provides an opportunity to learn about flooding and NbS, reproduce tensions, and conduct negotiations around urban planning choices. The results demonstrate the effectiveness of the method in stimulating debate and serving as an arena for discussion, but the assessment of the learning generated is more nuanced and calls for more experiments. Conclusion The Sim-MANA game has already demonstrated its potential for raising awareness of flood management and NbS. However, this tool alone is not sufficient to meet the objectives of increasing the capacity of local stakeholders in integrated flood management
Mesophotic protected habitats as refugia for the most at-risk elasmobranch species
No full textInternational audienceCoastal areas experience among the highest cumulated human pressures across the world's oceans with severe consequences on some fish populations which become scarce and at risk of local extirpation. Marine protected areas (MPAs) are essential for conserving these threatened populations, but they often cover only the most superficial waters and are not three-dimensionally extensive enough, leaving most mobile species with a large home range like elasmobranchs vulnerable to human pressures. Here we explored the role of mesophotic and deep-water habitats as refuges for elasmobranchs and the most at-risk species in the Parc Naturel Marin du Cap Corse et de l'Agriate, a large MPA in the Mediterranean Sea. Using the metabarcoding of 200 environmental DNA samples of seawater filtered between 1 and 835 m depth we revealed that fish species diversity was the highest in the mesophotic habitat (30-149 m). We also found the highest number of endangered species, including Evolutionary Distinct and Globally Endangered (EDGE) species such as Rostroraja alba and Squatina squatina, in this key habitat. Species composition varied significantly with depth, revealing a stratification linked to human pressure and environmental conditions. Protecting both mesophotic and deeper habitats (below 150 m) thus appears crucial to preserving biodiversity, species with unique functional roles but also those with unique phylogenetic diversity, in order to ensure ecosystem resilience in the face of climate change and overexploitation. The full protection of deep-water refuges within the western Mediterranean basin is essential to ensure the preservation of the most at-risk species, with the possibility of rewilding by connectivity other depleted adjacents habitats
Global patterns and drivers of untracked industrial fishing in coastal marine protected areas
No full textPublisher: American Association for the Advancement of ScienceInternational audienceMarine protected areas (MPAs) are expanding worldwide, but industrial fishing within their boundaries remains poorly understood. By combining vessel Global Positioning System data with satellite imagery, we detected industrial fishing in 47% of coastal MPAs worldwide between 2022 and 2024, with two-thirds of vessel detections (67%) untracked by public monitoring. These untracked vessels were most prevalent (80%) in MPAs with the most restrictive management category, which aims to prohibit all extractive activities. The presence and density of fishing vessels were mainly driven by the size and remoteness of MPAs rather than their management category itself. Including untracked vessels increased estimated fishing effort within MPAs by 28%, to an average of 4 hours per square kilometer per year. These results highlight the continued presence of industrial fishing vessels in MPAs and an important gap in our understanding of fishing pressure on protected areas worldwide
Obstacles et leviers dans la compréhension de discours scolaires par les élèves allophones. L’exemple de la classe de mathématiques
No full textInternational audienceIn this research, we focus on interactions during mathematics lessons, in classes welcoming allophone students. This involves analyzing the obstacles students may encounter in understanding the discourse of teacher and classmates and intervening in these exchanges themselves. With this in mind, the analysis of class sessions, recorded in two UPE2A classes, leads us to characterize the discourse heard in a mathematics class and to highlight various sources of difficulties: the multiplicity of enunciators and recipients; the variety of registers that students are required to use to understand the statements and to provide the expected responses; the possible polysemy contained in the gestures used by the teacher, etc. These considerations then lead us to question the teaching practices likely to overcome these obstacles and facilitate access to mathematical discourse for allophone students.Dans cette recherche, nous nous intéressons aux interactions en cours de mathématiques, dans des classes accueillant des élèves allophones. Il s’agit d’analyser les obstacles auxquels peuvent se heurter ces élèves pour comprendre les discours de l’enseignant ou de leurs camarades et intervenir eux-mêmes dans ces échanges. Dans cette optique, l’analyse des séances, enregistrées dans deux classes d’UPE2A, nous amène à caractériser les discours entendus en classe de mathématiques et à mettre en évidence diverses sources de difficultés : la multiplicité des énonciateurs et des destinataires ; la variété des registres pour comprendre les énoncés et apporter des réponses ; l’éventuelle polysémie contenue dans les gestes employés par l’enseignant, etc. Ces considérations nous conduisent alors à nous interroger sur les pratiques enseignantes susceptibles de pallier ces obstacles et de faciliter l’accès aux discours mathématiques pour les élèves allophones

Testing the effect of host availability on endobiont diversity: proposing the single hotel hypothesis
No full textInternational audienceThis study investigates the determinants of endobionts diversity within habitat-forming organisms, employing concepts from Island Biogeographic Theory (IBT) as a prospective explanatory framework. Sponges have long been considered “living hotels” due to the great diversity and abundance of their associated fauna. Various factors have been proposed to influence the composition and diversity of sponge-associated fauna, often relating to individual sponge characteristics, such as volume and oscular diameter. However, studies frequently contradict when identifying the main determinant. Focusing on two common massive sponge species, Agelas oroides and Sarcotragus foetidus, we collected, dissected, and analyzed 18 sponge specimens of A. oroides and 12 of S. foetidus from three sites in Crete, Greece (Eastern Mediterranean Sea). The sponges hosted 943 macroinvertebrates belonging to 94 different taxa, half of which were polychaetes. Crustaceans were the most abundant group, with over 50% of the individuals. Contrary to IBT predictions, A. oroides from areas with lower sponge abundance (i.e., “single hotel in town”), exhibited higher endofauna densities and richness. Notably, S. foetidus, which hosted large numbers of snapping shrimps, presented a different pattern, highlighting the importance of species-specific interactions on endobiont communities. Additionally, the reproductive state of S. foetidus correlated with increased endobiont richness, suggesting a potentially overlooked aspect of sponge-endobiont interactions related to the sponge’s reproductive state. These results emphasize the importance of sponges as “living hotels” and sponge communities as sources of biodiversity and highlight the complex influence of habitat availability and species-specific interactions on sponge-associated fauna

No full textInternational audienceObjective To evaluate the effectiveness of multi-bipolar radiofrequency ablation compared to standard laparoscopic myomec-tomy in treating uterine fibroids, focusing on women’s quality of life.Design Retrospective observational cohort study.Setting La Conception Hospital, APHM—Marseille, France.Patients 50 women with symptomatic fibroids treated between December 2021 and December 2023.Intervention Laparoscopic radiofrequency ablation or conventional laparoscopic myomectomy.Measurements and main results After excluding patients who did not complete the preoperative quality-of-life question-naire, 34 underwent myomectomy and 16 radiofrequency ablation. At 3 months, no significant differences were observed inHRQOL improvement (9.2 ± 34.3 vs 24.2 ± 28.2, p = 0.14), SSS (− 27.5 ± 31.5 vs − 23.3 ± 33, p = 0.66), or FSFI (0.9 ± 14.7vs − 1.5 ± 10.8, p = 0.40). The 6-month outcomes also showed no significant difference. Baseline fibroid-specific quality oflife was significantly and negatively associated with improvement (p < 0.05).Conclusion Both procedures improved quality of life and reduced fibroid-related symptoms at 3 and 6 months, with nosignificant difference. Myolysis showed fewer peri- and postoperative complications, suggesting a better safety profile andpotential as a conservative treatment option
Récifs coralliens, joyaux de biodiversité
No full textColorés et d'une grande beauté, les récifs coralliens du parc naturel de la mer de Corail forment de véritables forêts sous-marines. Ces univers complexes, encore large-ment méconnus, abritent une biodiversité exceptionnelle, où chaque élément structurant et chaque communauté biologique joue un rôle fondamental dans l'équilibredes écosystèmes. Bien qu'éloignés de la plupart des activités humaines et bénéficiant d'une haute protection, ces récifs sont aujourd'hui menacés par le réchauffementclimatique et des épisodes successifs de blanchissement. Face à ces dangers, les scientifiques de divers horizons collaborent pour mieux comprendre ces écosystèmeset anticiper les transformations à venir. Quelles espèces peuplent ces récifs ? Existe-t-il des connexions entre les récifs éloignés ? Comment ces récifs réagissent-ils aux canicules marines ? Quels sont les impacts passés et actuels de l'humain sur ces récifs éloignés ? Quelles relations entretient-il avec ces récifs ? C'est à cesquestions que ce chapitre tente d'apporter des éléments de réponse en s'appuyant sur de nombreuses expéditions naturalistes et études scientifiques faisant appelà diverses disciplines
