Dispersion des graines par le cerf élaphe (Cervus elaphus) pendant la saison de chasse : mise en place d’une expérimentation dans le Domaine national de Chambord

Abstract : Populations of wild herbivores have significantly increased in the last decades in the Northern hemisphere due to changes in farming practises and environmental management plans. This expansion has caused over- grazing, disruption of the physical properties of soil arising from animals stamping and standing and damage to bark and buds of target species. These animals also contribute to the functioning of forest ecosystems by dispersing plants and redistributing nutrients throughout their range. Epizoochory, the external transportation of seeds attached to skin appendages of animals (e.g., fur, feathers) is one of the main vehicles for seed dispersal. In this study, we examined the transportation of Xanthium strumarium L. diaspores with hook appendages by red deer (Cervus elaphus) on a hunting estate. The experimentation relies on the analysis of location data for hinds that have been captured and equipped with GPS collars and then released again in the National Estate of Chambord.
