Marine Ecology, Volume 47, Issue 3, May/June 2026.ABSTRACT The introduction of exotic species is one of the main drivers of biodiversity loss in aquatic ecosystems. The Harris mud crab Rhithropanopeus harrisii, native to the Atlantic coast of North America, was recorded in the Patos Lagoon estuary (southern Brazil) in the 1980s, likely introduced via ballast water. However, the effects of this invader

Sediment budget of a cuspate shoreline and its influence on spit development—Lagoa dos Patos, Brazil
Geo-Marine Letters, 2022 The coastal sediment budget is an essential tool to understand erosion/accretion patterns along coastlines and to predict future changes. This work is one of the first approaches of a coastal sediment budget study in a cuspate shoreline covering the whole embayment-spit system.

The role of cuspate spits on wave attenuation and energy redistribution in a coastal lagoon, Lagoa dos Patos, Brazil [PDF]
Geo-Marine Letters, 2020 This research uses a process-based model (Delft3D), validated with measured wave data, to investigate the controls that a cuspate shoreline and its associated submerged morphology have on wave generation, propagation, and attenuation within a large elongated lagoon (Lagoa dos Patos, Brazil).
