  abstract = {{T}he intensification of dry seasons is a major threat to freshwater biodiversity in {N}eotropical regions. {L}ittle is known about resistance to drying stress and the underpinning traits in {N}eotropical freshwater species, so we don't know whether desiccation resistance allows to anticipate shifts in biological diversity under future climate scenarios. {H}ere, we used the aquatic invertebrates that live in the rainwater-filled leaves of tank bromeliads, to examine the extent to which desiccation resistance of species measured in the laboratory predicts community response to drought intensification in nature. {W}e measured desiccation resistance in 17 invertebrate species (> 90% of the biomass usually found in bromeliads of {F}rench {G}uiana) by recording the median lethal time ({LT}50) of experimental populations exposed to controlled conditions of residual moisture. {I}n the field, we placed rainshelters above tank bromeliads to emulate drought scenarios ranging from the ambient norm to {IPCC} scenarios and extreme events, and we recorded the response of functional community structure. {LT}50 ranged from 4.18 to 19.06 days, and was related to cuticle content and dry body mass. {A}mong other functional indicators that represent strategies to optimize resource use under stressful conditions (e.g., habitat use, trophic specialization), {LT}50 was the best predictor of community structure responses along a gradient of emulated drought intensities. {T}herefore, species' {LT}5{O}s measured under laboratory conditions can be used to forecast aquatic community response to drying stress in nature. {A}nticipating how species will cope with drought has never been more important for environmental managers to support climate change adaptation. {W}e show that desiccation resistance in freshwater invertebrates is a key indicator of potential population size and local-global range shifts, and this could be especially true in the {N}eotropics where species have narrow physiological tolerances for climatic variation.},
