Leaf consumption by invertebrate aquatic shredders in the Amazon: effects of climate change and microbial conditioning
We grew leaves of Montrichardia arborescens in four microcosm chambers with different temperatures and CO2 concentrations simulating the scenarios of expected climate change. These leaves were used to feed shredders (Phylloicus) and to assess the effects of changes in leaf quality on their consumpti...
