Description
Tropical alpine ecosystems exhibit outstanding plant diversity and endemism while being particularly sensitive to the impacts of climate change. Although understanding spatiotemporal changes in plant species composition, richness and community structure along tropical alpine altitudinal gradients is of primary importance, both the functional and historical/biogeographic dimensions of vegetation diversity remain largely unexplored. We used Generalized Linear Models and multivariate analyses to assess changes in species, growth forms, and biogeographic groups richness and abundance, in response to habitat variables along an elevation gradient in seven summits (3800 to 4600 m asl) in the Venezuelan Andes, studied using the standardized approach of the GLORIA-Andes monitoring network.
