“…Greater wedge clam total biomass and larger body sizes prevailed on oceanic reflective beaches. This capacity of an intertidal species to prosper in harsh environments with coarse sediments, a turbulent swash climate and low food availability is favored by morphological, behavioral and trophic adaptations (Nel et al 2001), which in the case of the wedge clam are given by the following: (1) changing the trophic niche according to local conditions (Bergamino et al 2016); (2) an efficient and fast burrowing capacity to cope with short swash periods ; and (3) a more streamlined shape (wedgeshaped) with higher density, which is a function of shell thickness .…”

“…The wide surf zones of dissipative beaches could harbor ordersof-magnitude higher concentrations of surf zone diatoms (i.e. primary nutrition source for the wedge clam; Bergamino et al 2016) and dense larval settlement in the intertidal because of the presence of rip currents, which tend to be absent in the narrow surf zones of reflective beaches (Shanks et al 2010, Morgan et al 2018, Salant & Shanks 2018. The much higher recruitment of intertidal species in dissipative beaches has been widely ascribed to the nearshore hydrodynamics of their extended surf zones, which retain a high abundance of larvae and phytoplankton, forming semi-closed ecosystems (reviewed in McLachlan & Defeo 2018).…”

“…Se analizaron los cambios en los nichos tróficos isotópicos de las especies de la macrofauna bentónica de dos playas ubicadas en la costa atlántica de Uruguay en el departamento de Rocha caracterizadas por una morfodinámica contrastante (Bergamino, et al, 2016). Específicamente, para este estudio se consideró la fauna residente en una playa disipativa (Barra del Chuy: grano fino y pendiente suave) y otra reflectiva (Arachania: grano grueso y pendiente pronunciada).…”

“…Bergamino, Tudurí, Bueno, Brugnoli, Valenzuela, Martínez, Perez Becoña, Scarabino, García-Rodríguez tomea A. guyunusae durante un evento de acumulación en la playa disipativa de Barra del Chuy, con un filtro de fibra de vidrio Whatman GF/C. Las muestras de A guyunusae no fueron colectadas en la playa reflectiva, ya que acumulaciones de esta especie solo ocurren en la playa disipativa (Bergamino, et al, 2016).…”
