  abstract = {1. {E}cosystems are being stressed by climate change, but few studies have tested food web responses to changes in precipitation patterns and the consequences to ecosystem function. {F}ewer still have considered whether results from one geographic region can be applied to other regions, given the degree of community change over large biogeographic gradients. 2. {W}e assembled, in one field site, three types of macroinvertebrate communities within water-filled bromeliads. {T}wo represented food webs containing both a fast filter feeder-microbial and slow detritivore energy channels found in {C}osta {R}ica and {P}uerto {R}ico, and one represented the structurally simpler food webs in {F}rench {G}uiana, which only contained the fast filter feeder-microbial channel. {W}e manipulated the amount and distribution of rain entering bromeliads and examined how food web structure mediated ecosystem responses to changes in the quantity and temporal distribution of precipitation. 3. {F}ood web structure affected the survival of functional groups in general and ecosystem functions such as decomposition and the production of fine particulate organic matter. {E}cosystem processes were more affected by decreased precipitation than were the abundance of micro-organisms and metazoans. {I}n our experiments, the sensitivity of the ecosystem to precipitation change was primarily revealed in the food web dominated by the single filter feeder-microbial channel because other top-down and bottom-up processes were weak or absent. 4. {O}ur results show stronger effects of food web structure than precipitation change per se on the functioning of bromeliad ecosystems. {C}onsequently, we predict that ecosystem function in bromeliads throughout the {A}mericas will be more sensitive to changes in the distribution of species, rather than to the direct effects caused by changes in precipitation.},
