| Sumario: | Seabirds usually need productive waters and respond differently to environmental changesaccording to the oceanographic domain where they occur. The Arvoredo Marine Biological Reserve protectspart of an important ecological region in Brazil and shelters substantial marine biodiversity. Here we studiedseabird richness and abundance at this protected area to verify what kind of monitoring and managingprotocols are needed for future conservation actions. We surveyed the Reserve's islands and surroundingsea from the autumn 2010 to the autumn 2012. We also considered historical data from literature on seabirdcolonies to access specific issues related to management actions. Most of 14 surveyed species were migratory,rare, and recorded during winter. The Kelp Gull (Larus dominicanus) was dominant and its abundancepattern alternated with those of the other species along seasons. Deserta Island is an important breeding siteand Galé Islets is an important stopover site at the Reserve. Few places along the Brazilian coastline supportbreeding colonies such as the ones in the Arvoredo Marine Biological Reserve. However, the Reserve needsseabird active management to fulfill its purpose of protecting marine biodiversity. Breeding success must beconsidered as an indicator for intervention and control of predators in the Reserve. The effects of climatechanges and overfishing near the Reserve affect the seabirds therefore managers should join a large-scaleintegrated coastal management and marine spatial planning. A long-term monitoring protocol at-sea and inthe colonies using new technologies also can help in this process |
