Abstract: Salt marshes are intertidal coastal ecosystems flooded irregularly by salt water. Ants (Hymenoptera: Formicidae) are important predators of invertebrates in most ecosystems and are prominent herbivores in many Neotropical communities, including salt marshes. The aims of this study are to quantify the feeding preference of ant communities and to estimate the diversity and similarity along the Lagoa dos Patos Estuary salt marshes. We chose three salt marshes in Lagoa dos Patos Estuary along a salinity gradient: Low Estuary (32°10’65†S; 052°08’52†W), Middle Estuary (32°02’01’’S; 052°10’45†W) and Upper Estuary (31°53’33†S; 052°14’33†W). We used transections with protein and glucose baits. We found 25 ant species. Most of them was attracted by the two types of bait, being considered omnivores. We recorded the largest catch at the closest point to the sea, the Low Estuary, on both baits. We did the smallest catches in the Upper Estuary (K = 5.204; df = 2; P
