Warming of aquatic ecosystems disrupts aquatic–terrestrial linkages in the tropics
Using tank‐bromeliads, the authors experimentally investigated for the first time how aquatic–terrestrial linkages are affected by warming in the tropics. In contrast to temperate regions, warming is predicted to cause strong declines in tropical aquatic insect emergence into terrestrial ecosystems, while variably affecting terrestrial detritus ...

Fisheries management influences phytoplankton biomass of Amazonian floodplain lakes
Tropical freshwaters fisheries typically assume that fish biomass is controlled by bottom‐up mechanisms, so that overexploitation of large predators would not affect overall ecosystem productivity. Our results, however, show that top‐down forces are important drivers of primary productivity in tropical lakes, above and beyond the effects of bottom‐up ...

Turbulence and Gas Transfer Velocities in Sheltered Flooded Forests of the Amazon Basin
Abstract Seasonally flooded forests along tropical rivers cover extensive areas, yet the processes driving air‐water exchanges of radiatively active gases are uncertain. To quantify the controls on gas transfer velocities, we combined measurements of water‐column temperature, meteorology in the forest and adjacent open water, turbulence with an ...
