“…Dense accumulations of the surf-zone diatom Asterionellopsis glacialis generally form dark-brown patches at the meso/supralittoral (Odebrecht et al 2013), representing an important food source for terrestrial coleopterans (Bledius spp.) and the talitrid amphipod Atlantorchestoidea brasiliensis, a scavenger/detritivore species (Gianuca 1983).…”

“…The extensive southern Brazilian coast is predominantly of the intermediate type and presents high microalgae biomass mainly granted by accumulations of the surf-zone diatom Asterionellopsis glacialis (Castracane) Round throughout the year (Odebrecht et al 2010(Odebrecht et al , 2013. During high A. glacialis concentrations (10 7 to 9 cells L -1 ), high primary production rates (6.4 mg C L -1 h -1 ) and chlorophyll a values (up to 4.7 mg L -1 ) can be registered (Odebrecht et al 1995.…”

“…Food webs at sandy environments are mainly based on marine sources like wrack and carrion (Colombini & Chelazzi 2003, Dugan et al 2003, microphytobenthos (Delgado 1989) and surf-zone diatoms (Odebrecht et al 2013) which support (i) an independent interstitial food web; (ii) a surf-zone microbial loop; and (iii) a macroscopic food web , Heymans & McLachlan 1996. The knowledge about the food web structure and trophic relationships on sandy shores has growing with the implementation of stable isotopes (SI) techniques (Colombini et al 2011) and recent studies have evidenced that the number of trophic pathways and food web complexity are strongly linked to morphodynamics, increasing significantly from reflective to dissipative environments (Lercari et al 2010, Bergamino et al 2011.…”

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.

“…The high rates of primary production (ANDRADES et al, 2014;ODEBRECHT et al, 2014) and turbidity (ALSINA; CÁCERES, 2011) associated to these coastal environments makes them essential habitats for several species of fish, providing food and protection from predators (LASIAK; MCLACHLAN, 1987;BLABER;BLABER, 1980;ESPOSITO et al, 2013;PATTRICK;STRYDOM, 2014;FAVERO;DIAS, 2015). Such shallow and turbulent environments favour, in most cases, the presence of fish in early stages of life (LAYMAN, 2000).…”

Gonzalez and Vaske Junior: Feeding of Atherinella blackburni in Brazil 346Feeding ecology of the beach silverside Atherinella blackburni (Atherinopsidae) in a tropical sandy beach, Southeastern Brazil A ecologia alimentar do peixe-rei (Atherinella blackburni) na zona de arrebentação de uma praia arenosa tropical, localizada no sudeste do Brasil, foi acessada a partir da análise do conteúdo alimentar de 198 peixes. Fatores como o tamanho, a estação do ano e o período do dia foram analisados para compreender como estes influenciam a dieta da espécie. Os resultados mostram que A. blackburni é um peixe nerítico costeiro com amplo nicho alimentar. As presas mais recorrentes foram os crustáceos zooplanctônicos, insetos e moluscos bentônicos, sendo os crustáceos da subclasse Copepoda o item dominante na dieta em ocorrência e abundância. A. blackburni aparenta possuir uma leve mudança ontogênica em sua dieta, variando de moluscos bentônicos para crustáceos e em seguida para insetos ao longo do seu ciclo de vida. A atividade diária também demonstrou ser um fator importante para a ecologia alimentar de A. blackburni. O predomínio de peixes pequenos durante o período da manhã, juntamente com as principais presas para esta classe de tamanho, sugere que indivíduos pequenos utilizem as áreas mais rasas para alimentação durante o período da manhã e, durante a noite, movem-se para águas mais profundas em busca de proteção contra predadores. A. blackburni appears to have a slight ontogenetic shift in its diet, changing from benthic molluscs to crustaceans and insects along its life cycle. The diel activity also reveals to be an important factor to the A. blackburni feeding ecology. The predominant occurrence of small fish during the morning, along with the main preys for this size class, suggests that small individuals use shallower waters as feeding grounds during the morning and, during the night, they move to deeper waters for protection against predators. Resumo AbstRActDescriptors: Diel activity, Diet, Ontogenetic shift, Resources partitioning, Surf zone, Zooplanktivorous.
