“…Confined to a few favorable patches of habitat within a mosaic of natural physical drivers, many species disappear or become less abundant on beaches disturbed by human stressors (Costa et al 2022). On the other hand, mobile species are able to change their distribution and select habitats that have more favorable conditions and meet their specific demands for resources (Meager et al 2012, Rangel et al 2022.…”

Confined to a few favorable patches of habitat within a mosaic of physical drivers, many species disappear from human-disturbed beaches. However, mobile species may change their distribution and select more appropriate habitats as a response to disturbance. Ghost crabs are one of the few beach resident animals capable of moving over considerable distances, but usual habitat homogeneity of urban beaches theoretically prevents them from finding refuge. Here, I tested whether access walkways provide a habitat for ghost crabs on four beaches in southeastern Brazil. I counted and measured burrow opening diameter under walkways and in surrounding transects located at various distances from these structures between June 2020 and May 2021. Mean burrow density was three times higher in transects out of walkways than under the walkways. However, burrows were larger and positioned farther from the waterline under walkways. Walkways thus possibly provide protection for ghost crabs from trampling and vehicle traffic in urban beaches and could therefore be applied as an environmental enrichment tool in the management and conservation of sandy beach biodiversity.

“…Studies were also spatially restricted to supratidal and intertidal zones, with only a few studies sampling the subtidal or the whole across-shore gradient (e.g., Corte et al, 2019;Corte et al, 2020;Corte et al, 2022). Investigations mainly focused on macrobenthos, despite recent contributions to fish (Shah Esmaeili et al, 2022) and bird ecology (da Rosa Leal et al, 2013;Linhares et al, 2021;Rangel et al, 2022). There is incipient information on microorganisms and few studies assessed the ecology of meiofauna (reviewed in Maria et al, 2016).…”
