  abstract = {{A} large part of freshwater microorganism biodiversity is contained in the bromeliad ecosystem of the {N}eotropics, which form a multitude of small islands in a terrestrial matrix. {W}hile aquatic communities of bromeliads and their food-web organisation are relatively well documented, processes that shape diversity in such small water bodies remain largely understudied. {B}ased on 217 bromeliad ecosystems from six sites located in {F}rench {G}uiana, we determined the factors that shape the diversity pattern of algal communities. {W}e considered a broad range of environmental and ecological variables, including canopy openness, habitat characteristics, and invertebrate biomass, to identify the main drivers of algal community structure and biodiversity across bromeliads in a c. 25,000 km(2) region. {W}e found no evidence of random distribution or spatial structuring of algal communities. {A}lgal biomass was mainly influenced by habitat size and complexity, particulate organic matter content, and light energy, while algal richness was primarily controlled by habitat size. {C}hange in community structure as habitat size increases was driven by species turnover with increasing proportion of filamentous taxa. {O}ur results indicate that, due to the large diversity of aquatic habitats they provide at a small spatial scale, bromeliads are critical ecosystems sustaining freshwater microorganism biodiversity.},
