Some aquatic insects have strategies thatimprove the permanence (resistance), while others use strategies that favor recoloni-zation (resilience). Therefore, we carried out a manipulative experiment to understandthe influence of functional characteristics of aquatic insects in their permanence andrecolonization against hydrological disturbances in streams in the biodiversity hot-spot of the Cerrado of Brazil. We placed 200 artificial substrates in five streams andsubmitted them to changing water flow regimes that differed both in frequency andintensity, and we observed the response of the aquatic community for 39 days. Weused a hierarchical Bayesian approach to estimate the probabilities of permanenceand recolonization of each life strategy group (nine groups). We observed that themost intense changes in the water flow tended to affect the permanence of almostall groups, but the intensity of this effect reduced over time. On the other hand, lessfrequent disturbances, regardless of intensity, tended to reduce the permanence ofmost groups of aquatic insects over time. The different effects of disturbance inten-sity may have been related to a greater recolonization capacity of some groups. Theresults we present are worrisome in a scenario of reduced riparian vegetation aroundstreams and with the expectation of precipitation becoming more concentrated inshorter periods of time due to climate change in the Cerrado hotspot, reducing theoccurrence of many groups of aquatic insects in their habitat, particularly those withtraits associated with resistance against hydrological disturbance.engAcesso Abertohttp://creativecommons.org/licenses/by-nc-nd/4.0/Bayesian inferenceCerrado streamsFunctional traitHierarchical modelResistance–resilience axisSpace-state designArtigo10.1002/ece3.8749
