BioMareau-II : Effet de l'envahissement des îles de Loire par l'érable négondo sur la diversité en bryophytes épiphytes

Abstract : The Box elder is an American invasive exotic tree currently spreading in the Loire watershed. This species have a negative impact on native vascular flora and in particular on riparian forest tree species regeneration of such as black poplar. But we do not know the invasion effects on epiphytic bryophyte communities. After a brief overview of the potential theoretical effects of this invasion, we let's show the preliminary results from inventories comparing the communities of epiphytic bryophytes on Box elder to those on Black poplar. We compare the species richness and abundance of species at the tree level (α) and globally at the scale of the whole study (γ), the level of scarcity of species encountered on each tree species and the effect of environmental and dendrometric variables.
