Summary:The objective of this study is to provide information about a harbour-fouling community dominated by Metri dium senile in southern Patagonia. Several steel tubes from the wharf of Puerto San Julián were extracted to perform repair tasks, allowing the attached benthic community to be studied. Sampling was conducted at three levels: lower intertidal, 3-4 m depth and 6-7 m depth. In the lower intertidal, M. senile had a relative abundance of 43%, the most abundant accompanying species being Perumytilus purpuratus, Mytilus edulis platensis and Aulacomya atra atra. At subtidal level, the anemone showed relative abundances of 64% and 65%, and was accompanied by Monocorophium insidiosum at 3-4 m depth and by polychaetes of families Sabellidae and Syllidae at 6-7 m at depth. In the lower intertidal, epibiosis was more frequent on P. purpuratus, A. atra atra and M. edulis platensis, while in the subtidal, the richness of substrate-organisms increased significantly and the anemone was fixed to A. atra atra, M. edulis platensis, Paramolgula gregaria, Crepipatella dilatata, Austromegabalanus psittacus, Hiatella arctica, Polyzoa opuntia, Pyura sp. and Sabellidae tubes. The ability of M. senile to settle on many different organisms, along with other strategies, makes it a colonizer able to displace other species that could compete with it for substratum. Given the cosmopolitan nature of M. senile, the fact that this species has not been previously reported in the coastal zone of the region, and the results of our study, we discuss the possibility that this sea anemone is an invasive alien species in southern Patagonia, or at least a cryptogenic species.Keywords: biofouling; benthic communities; Actiniaria; Metridiidae; epibiosis; exotic species; southern Patagonia.

Varios pilotes de acero del muelle de Puerto San Julián fueron extraídos para efectuar tareas de reparación, permitiendo realizar un estudio de la comunidad bentónica adherida a ellos. El muestreo fue realizado en tres niveles: intermareal inferior, submareal a 3-4 m y submareal a 6-7 m de profundidad. En el intermareal inferior, M. senile presentó una abundancia relativa del 43%, encontrándose acompañada por Perumytilus purpuratus, Mytilus edulis platensis y Aulacomya atra atra entre las especies más abundantes. En los niveles submareales presentó abundancias de 63 y 65%, encontrándose acompañada por el anfípodo Monocorophium insidiosum en el nivel de 3-4 m y por poliquetos de las familias Syllidae y Sabellidae en el nivel de 6-7 m de profundidad. En el intermareal inferior, la epibiosis tuvo mayor frecuencia sobre P. purpuratus, A. atra atra y M. edulis platensis, mientras que en los niveles submareales la diversidad de organismos sustrato se incrementó significativamente, observándose fijación sobre A. atra atra, M. edulis platensis, Paramolgula grega ria, Crepipatella dilatata, Austromegabalanus p...

PINOTTI, R.M., MINASI, D.M., COLLING, L.A., BEMVENUTI, C.E. A review on macrobenthic trophic relationships along subtropical sandy shores in southernmost Brazil.http://dx.doi.org/10.1590/1676-06032014006914Abstract: Main trophic relationships that occur along the exposed sandy shores in southernmost Brazil (,336 S) are established taking into account several biological compartments operating at morphodynamically distinct environments. Beaches are predominantly of the intermediate type but some stretches of coastline are truly dissipative (Cassino Beach) or tending-to-reflective (Concheiros Beach), presenting thus diverse biological compartments and inhabitant macrobenthic assemblages. Dense concentrations of the surf-zone diatom Asterionellopsis glacialis are responsible -at least for the intermediate shorelines -for the most year-round primary production, sustaining several consumers up to tertiary level. Among them, bivalves Amarilladesma mactroides, Donax hanleyanus and the hippid crab Emerita brasiliensis can account for more than 95% of all the surf-zone secondary production, in addition to the elevated biomass of the suspension-feeder polychaete Spio gaucha and the scavenger isopod Excirolana armata. Crabs, whelks, carnivorous polychaetes, seabirds and surf-zone fishes may also be present and occupy superior trophic levels depending on the beach morphodynamics. Based on the high species richness, abundance and the role of macrobenthic fauna in transferring matter and energy to seabirds and the surf-zone fish assemblages, we address this important issue on the Southwestern Atlantic ecology. Conservation efforts should be implemented for the southernmost Brazilian sandy shores, at least for those non urbanized areas.

“…Through competitive exclusion, habitat alteration, facilitation and predation (Race 1982;Crooks 1998;Grosholz et al 2000;Ruiz et al 1999), invasive species are able to modify the environment where they are introduced causing drastic changes in the native faunal and floral assemblages and leading to the homogenization of the global biodiversity (Carlton 1989). Although the Argentinean coastline was long considered pristine, it is now severely affected by biological invasions (Orensanz et al 2002;Bortolus and Schwindt 2007). Among the most emblematic exotic species in this region is the acorn barnacle Balanus glandula Darwin (1854); which was introduced during the early 1970's and first reported from Mar del Plata Harbor (38°S; Spivak and L'Hoste 1976).…”

“…Nowadays, almost 40 years later, B. glandula is well established on most rocky shores and in ports along the coast of Argentina from San Clemente del Tuyú (36°21 0 S 56°43 0 W) to Río Grande (53°50 0 S 67°33 0 W, Schwindt 2007). This barnacle is native to the Pacific coast of North America, ranging from the Bering Sea to Baja California (Newman and Ross 1976) and it has been introduced only to Japan and Argentina (Kado 2003).…”

Balanus glandula, an east Pacific acorn barnacle from rocky shores, was introduced to Mar del Plata, Argentina more than 40 years ago and has spread over 17 latitudinal degrees southward. Here we report the first record of this species living in a softbottom environment colonizing the salt marsh plant species Limonium brasiliense, Spartina densiflora, S. alterniflora and Sarcocornia perennis. In addition, we describe the size frequency distribution, density and spatial distribution of the barnacles colonizing the different plant species. The size frequency distribution of Balanus showed a bimodal pattern in all plants. Barnacles were mostly large in S. densiflora, but small in S. alterniflora, with more balanced distributions of small and large barnacles on S. perennis and L. brasiliense. The highest density of barnacles was observed on S. perennis (x = 35.8 ind/cm 2 , SD = 40.5) and S. alterniflora (x = 33.8 ind/cm 2 , SD = 23), while the lowest on L. brasiliense (x = 1.5 ind/cm 2 , SD = 1.18) and S. densiflora (x = 0.17 ind/cm 2 , SD = 0.09). More than 90% of the barnacles on any given plant were found living. While barnacles colonized only the first few centimeters above the soil surface level in S. alterniflora and L. brasiliense, they reached their highest point on S. perennis. The finding of a rocky shore species successfully colonizing softbottom marshes within an invaded region brings new perspectives to discussions in biological invasion ecology, and raises additional considerations for coastal environmental management.
