Article Reference Biodiversity in mountain groundwater: the Mercantour National Park as a European hotspot
Abstract Mercantour National Park (France) is recognized as a highly heterogeneous region with extremely varied geology, geomorphology and climatology, resulting in an exceptional biodiversity. From a hydrogeological point of view, it is also an area organized of small and discontinuous aquifers, their obligate groundwater fauna remaining absolutely unknown. This work explores the species richness of groundwaters in Mercantour National Park, using a sampling design at the catchment (six major valleys) and aquifer scales (aquifers in consolidated rocks and unconsolidated sediments). A major finding of this study is the discovery of 44 species restricted to groundwater, from which 43 are new to the Park and 10 are new to Science. Although a relatively small number of sites were sampled (53), the area may be considered as a new hotspot of groundwater biodiversity at the European level. The particular structure of the groundwater network, the high environmental heterogeneity of the region, and its Mediterranean position may explain such a high biodiversity. Species rarefaction curve showed that many species have yet to be discovered in groundwater of the Mercantour National Park. With more than 78% of species collected in the hyporheic zone, this study also highlights the importance of porous aquifers in sustaining groundwater biodiversity of mountainous regions. Key words: groundwater invertebrates, stygobionts, biodiversity hotspot, Mercantour National Park, hyporheic zone, spring. Résumé Biodiversité dans les eaux souterraines de montagne. Le Parc National du Mercantour: un ‘hotspot’ européen. Le Parc National du Mercantour est une région physiquement très hétérogène, avec des faciès géologiques, géomorphologiques et climatologiques extrêmement variés, à l’origine d’une biodiversité exceptionnelle. D'un point de vue hydrogéologique, son réseau souterrain est organisé en aquifères discontinus et de petite taille, dont la faune aquatique (stygobie) est aujourd’hui inconnue. Ce travail explore la richesse spécifique des eaux souterraines du Parc National du Mercantour, après la mise en œuvre d'un plan d'échantillonnage prenant en compte l'hétérogénéité environnementale à l’échelle du bassin versant (six vallées majeures) et de l'aquifère (aquifère fissuré ou poreux). Le premier fait marquant est la récolte de 44 espèces stygobies, 43 étant nouvelles pour le parc et 10 nouvelles pour la Science. Sur la base d’un nombre relativement faible de sites (53), cette zone peut être considérée comme un nouveau ‘hotspot’ de biodiversité des eaux souterraines à l'échelle européenne. La structure particulière du réseau hydrogéologique, l'hétérogénéité environnementale élevée, et la position méditerranéenne de cette région, pourraient expliquer une telle biodiversité. La courbe de raréfaction des espèces montre que nos connaissances sur le Mercantour sont néanmoins loin d'être complètes et que de nombreuses espèces restent encore à découvrir. Avec plus de 78 % des espèces récoltées dans la zone hyporhéique, ce travail souligne également le rôle des aquifères poreux, dans le maintien de la biodiversité des eaux souterraines de montagne. Mots-clés: invertébrés souterrains, stygobies, ‘hotspot’ de biodiversité, Parc National du Mercantour, zone hyporhéique, source.

Article Reference Biofluorescence in Morelia, Malayopython and Python: first reports for the Pythonidae
Ultraviolet (UV) induced biofluorescence in snakes has been underexplored compared to lizards. This study reports for the first time UV fluorescence in several Pythonidae species, including Morelia viridis, Malayopython reticulatus, and Python regius. Specimens were examined under both white and UV light, revealing that UV fluorescence in these snakes is likely skin-based, induced by chemical compounds rather than bone-based as seen in other reptiles. Notably, Morelia viridis and M. azurea exhibited a golden mustard yellow fluorescence, while Malayopython reticulatus displayed a complex pattern with intense yellow fluorescence. The study also found that UV fluorescence is absent in ethanol-preserved specimens, suggesting the degradation of fluorescent compounds during preservation. These findings contribute to the understanding of UV fluorescence in snakes and highlight the need for further research on its functional significance and the specific molecules involved.
