Macrobenthic surf zone communities of temperate sandy beaches: spatial and temporal patterns

Abstract: The spatial and temporal patterns within the surf zone epibenthic assemblages were studied in a coastal fringe of Argentina to determine whether assemblage compositions, abundance, species richness and diversity vary spatially and temporarily. Sampling was conducted seasonally in two sandy beaches over 2 years with a benthic sledge used to collect the fauna in the upper centimeters of soft bottom sediments and the epifauna on the sediment surface. Physical variables were measured in the same coastal sites wher… Show more

“…Regarding sandy beaches, the use of such an approach is still emerging (Veloso & Cardoso 2001, Carcedo et al 2014). The limited number of studies assessing how the combination of several factors structures benthic macrofaunal assemblages may be explained by the complexity of analysing multivariate data accounting for effects of time, space, and other environmental variables simultaneously.…”

“…In relation to these alterations, Brown & McLachlan (2002), commented on the importance of storms in influencing the molding stage of beaches and in the definition of these ecosystems. When the greatest movement of sand occurs, large quantities of sediment can be removed from the upper margin and deposited in the surf zone (Carcedo et al, 2014), increasing wave energy (Masselink & Short, 1993). Furthermore, waves are capable of moving sediment from the sublittoral zone, depositing it in the intertidal zones.…”

“…Another important factor is marine currents. Carcedo et al (2014), after performing studies along the Argentinian coast, commented on the influence of these currents on the exportation of warm water, which is a process that not only results in increased temperatures in the surf zone but also elevates suspended sediment loads, allowing for the occurrence of some non-resident invertebrates typical of other ecosystems, such as some cnidarians and crustaceans typical of estuaries (Gibbins et al, 2007;Elías et al, 2007;Hoffmeyer & Mianzan, 2007).…”

“…In addition, M. acherusicum differs from M. insidiosum by the following features (those of M. insidiosum in parentheses): antenna 1 of males, peduncle article 1 without process (ventromedial margin with a short and blunt proximal process); antenna 2 of males, peduncle article 5 with proximal process on ventromedial margin (without proximal process); gnathopod 1, dactyl extending well beyond the palmar angle (barely extending); gnathopod 2, dactyl with 2 teeth on posterior margin (with 3 teeth); pereopod 3 and 4, anterior margin of basis without long setae (moderately to strongly setose); uropod 2, outer margin of inner ramus with robust setae (lacking setae) (see Bousfield and Hoover 1997;LeCroy 2004). In the Argentine Sea, M. insidiosum has been recorded from the coast of Buenos Aires Province (Ieno and Bastida 1998), including Mar del Plata port (Rivero et al 2005;Lopez Gappa et al 2006;Albano et al 2013;Carcedo et al 2015), as well as other ports of Patagonia: San Antonio Este, Puerto Madryn, Puerto Deseado, San Julián and Ushuaia (Sueiro et al 2012;Schwindt et al 2014;Martin et al 2015).…”
