  abstract = {{A}noxygenic phototrophic bacteria have recently been recognized as a ubiquitous component of microbial communities in lakes and marine environments, but studies of the ecological factors that control their significance are scarce. {W}e conducted a manipulative field experiment using natural freshwater microcosms, the tank bromeliad ecosystem, to test the response of anoxygenic and oxygenic phototrophic microorganisms to an environmental gradient across the forest edge. {W}e assessed the biomass of these photosynthetic communities by their pigment content and used structural equation modeling to evaluate the importance of different habitat variables as ecological drivers. {W}e show that anoxygenic phototrophic bacteria are primarily driven by small detrital organic particles rather than directly by light. {I}n contrast, light and habitat size were the main factors controlling the biomass of oxygenic phototrophic microorganisms. {A}noxygenic phototrophic bacteria inhabiting the bromeliad ecosystem represent huge concentrations of bacteriochlorophyll a relative to large pelagic environments and form an essential and dominant part of photosynthetic biomass across a wide range of ecological conditions. {T}hese freshwater photoheterotrophs are likely to play a pivotal and unsuspected role in energy flow and nutrient cycling in neotropical forests.},
