  abstract = {{C}rustacean communities are shaped by a series of ecological processes, but the degree to which different spatial and environmental dimensions affect them in surrounding estuarine-coastal gradients remains unclear. {H}ere we analyzed decapod community data (crabs and shrimps) from the {D}oce {R}iver estuary and its adjacent marine coast, to test and quantify the effects that spatial and environmental factors have had on these communities three years after the {F}undao mining dam failure of {N}ovember 2015. {W}e sampled communities monthly from {O}ctober 2018 to {S}eptember 2019 in 18 sampling sites distributed in three zones (estuary, nearshore, and offshore), resulting in 216 samples and 29 recorded taxa. {S}patial eigenvector-based methods and variation partitioning approaches were used to test and quantify the pure and joint effects of spatial and environmental processes on the communities over different seasons. {T}he spatial structures of the community composition presented differences among the four studied seasons, being driven by environmental heterogeneity as well as spatial processes unrelated to our measured variables (temperature, salinity, depth, turbidity, dissolved oxygen and p{H}). {S}pecifically, the species composition and species richness responded the most to turbidity, p{H}, and depth during the rainy seasons, as well as salinity during the dry seasons. {T}he variability of decapod composition surrounding the {D}oce {R}iver mouth is seasonally affected by a different set of environmental and spatial factors, with low intrusions of saltwater in the estuarine sector impacting the distribution of stenohaline marine species. {O}ur results both partly uncover and emphasize the complexity resulting from environmental heterogeneity and anthropic pressures, stressing the need for further studies on local spatio-temporal dynamics of decapod fauna and other organisms to inform conservation and management actions.},
