Sandy beaches are dynamic ecotones where beach-profile morphology, sediment properties, and allochthonous organic subsidies interact with intertidal benthic communities. We assessed seasonal variation in beach morphology, sediment granulometry, beach-cast macroalgal wrack, and associated macrofaunal assemblages at two tropical sandy beaches on the central Brazilian coast: Putiri Beach and Fifteen Beach. Both beaches were class...

Introduction Species sorting by environmental gradients is an important driver of benthic meiofaunal biodiversity in marine ecosystems, but there are few attempts to test these effects in coastal habitats. Methods In this study, we evaluated the importance of habitat filtering in shaping meiofaunal communities across rocky tide pools and nearby sandy beaches in the Eastern Brazilian Marine Ecoregion, SW Atlantic. We proposed t...
