Projets de recherche

Ont été ou sont actifs dans le Vallon les projets suivants, menés en général autour des groupes de la FGSE et de la FBM, parfois autour de travaux de Master ou de thèse de doctorat ou en lien avec d’autres institutions universitaires romandes et alémaniques :

relevés météorologiques et monitoring, dynamique des sols, respiration des sols, flux de carbone, étude de l’hydrologie du Vallon, processus hydrologiques, géomorphologie de la végétation, dynamique évolutive des sols, dendrochronologie, mechanisms of calcium-mediated soil organic carbon stabilisation, traçage sédimentaire, réchauffement climatique, faune, inventaire faunistique, pédologie et micro-organismes, végétation, caractérisation hydrologique du Vallon, étude géophysique, projet crowd-water de médiation scientifique, biodiversity and biogeography of soil protists in continental and oceanic islands, …

Ces travaux donnent lieu à des publications dont voici quelques exemples :
