  abstract = {{I}n the tropics, human disturbance continuously challenges initiatives for habitat conservation. {I}n these regions, as economical budgets for conservation shrink, conservation planning requires precise information on when and how different kinds of disturbance may affect natural populations, but also on adequate experimental designs to monitor them. {D}ue to their high diversity, ecological role, stable taxonomy and facilities to sample, dung beetles are used in biodiversity surveys for conservation purposes worldwide. {H}ere we studied the short-term effects of dung beetle communities to an important and widespread ecological disturbance due to road construction in the {A}mazon basin. {W}e surveyed the dung-beetle community in a spatio-temporal context, i.e. in transects located at 10, 50 and 100-m from a newly constructed, 10-m wide, paved road. {T}he sampling periods took place 1, 3 and 6 months after the construction. {D}uring the survey, we collected 4895 specimens that belong to 69 species in 19 dung beetles genera. {S}ix dung beetles species ({C}anthon aequinoctialis, {C}. luteicolis, {D}ichotomius fortestriatus, {E}urysternus caribaeus, {E}. con fusus and {O}nthophagus haematopus) accounted for 55% of all individuals collected. {B}oth species diversity and abundance tended to decrease during the 6 months after the opening of the road, but not with distance from the road. {A}ccordingly, an {NMDS} analysis revealed clear differences in dung beetle community composition and biomass among the three sampling periods, but not with respect to transect location. {H}owever, the number of rare species tended to increase toward the forest interior. {A} detailed analysis of dung beetle species among transects revealed that 5 species ({S}ylvicanthon bridarollii {C}anthidium sp. 2, {C}. sp. 6, {C}. sp. 7 and {O}ntherus diabolicus) were more abundant when getting further from the road. {O}n the contrary 6 species ({E}urysternus hamaticollis, {E}. velutinus, {E}. con fusus, {E}. caribaeus, {D}eltochilum oberbengeri and {D}. orbiculare) increased in abundance in the transect next to the road. {O}ur study therefore confirmed that while overall community metrics did not respond to road construction, several rare dung beetle species did, within an incredibly rapid time frame. {W}hile pattern based descriptions of dung beetle responses to anthropogenic activities are common in the literature, our findings suggest that effect of roads is certainly under emphasized.},
