“…Species-specific effects were not considered in our study, as we used communities consisting of various crustose coralline species in our experiments. Different CCA species affected macroalgal growth differently in a Brazilian coastal system (Villas Boas & Figueiredo 2004), and are known to have species-specific effects on coral recruitment (Harrington et al 2004). Furthermore, CCA species have potentially beneficial effects on macroalgal growth in some ecological situations (Diaz-Pulido & McCook 2004).…”

“…Some calcareous red algae (family Corallinaceae) are known to defend themselves against epibionts throughout a physical antifouling mechanism of epithallus sloughing (e.g., LITTLER; LITTLER, 1999; VILLAS-BÔAS; FIGUEIREDO, 2004), however, without the release of chemical compounds with antifouling activity.…”

Antifouling activity of seaweed extracts from Guarujá, São Paulo, Brazil

A B S T R A C TMarine biofouling historically constitutes one of the major constraints faced by mankind in its oceanic activities. The search for alternatives to TBT-based antifouling paints has led several researchers to focus efforts in the development of environmentally friendly natural compounds. This work has contributed with this search, testing the antifouling potential of crude organic extracts from four seaweed species collected at Praia Branca, Guarujá district, São Paulo, Brazil. Throughout laboratory antifouling assays in which the attachment of a common fouling organism, the brown mussel Perna perna, was employed, antifouling activity (p < 0.05) was detected in natural concentrations of the extracts of Jania rubens (Rhodophyta, Cryptonemiales) and Bryothamnion seaforthii (Rhodophyta, Ceramiales), while Dictyopteris delicatula (Phaeophyta, Dictyotales) and Heterosiphonia gibbesii (Rhodophyta, Ceramiales) did not exhibit fouling inhibition. From the algae that exhibited antifouling activity, J. rubens presented best performance when compared to that of B. seaforthii. Future field studies would be necessary to obtain results that can better reflect natural conditions, as well as to assess the activity spectrum of the antifouling activity presently recorded. Further bioassay-guided purification of the active extracts can lead to new alternatives to the metalbased antifouling paints currently in use. R E S U M OA incrustação biológica constitui, historicamente, um dos maiores problemas encontrados pelo homem em suas atividades no mar. A busca por alternativas a tintas antiincrustantes contendo tributilestanho (TBT) tem levado diversos pesquisadores a concentrar esforços no desenvolvimento de substâncias naturais menos danosas à biota marinha. Este trabalho procurou contribuir com essa busca, testando o potencial antiincrustante de quatro diferentes espécies de macroalgas da Praia Branca, município de Guarujá, SP. Através de testes antiincrustantes em laboratório utilizando a fixação de um organismo incrustante comum, o mexilhão Perna perna, foi constatado que os extratos de Jania rubens (Rhodophyta, Cryptonemiales) e Bryothamnion seaforthii (Rhodophyta, Ceramiales), à concentração natural, apresentaram atividade antiincrustante significativa (p < 0,05), enquanto Dictyopteris delicatula (Phaeophyta, Dictyotales) e Heterosiphonia gibbesii (Rhodophyta, Ceramiales) não demonstraram eficiência na inibição da fixação de bissos do molusco. Das algas que indicaram potencial atividade contra a incrustação, J. rubens apresentou melhor desempenho em relação a B. seaforthii. Futuras investigações em campo serão necessárias para a obtenção de resultados que possam refletir melhor as condições naturais, bem como avaliar o espectro de ação da atividade antiincrustante observada. A purificação guiada por bioensaios dos extratos ativos poderá levar a novas alternativas para os antiincrustantes metálicos atualmente em uso.

“…Interestingly, GPP, R, and chlorophyll a content of dead maerl were of the same magnitude as for living maerl. Although live algae prevent bio-fouling by shedding their surface layers (Keats et al, 1997;Villas Bôas and Figueiredo, 2004), post-mortem colonisation by photosynthetic endolithic assemblages may occur within dead crusts (Diaz-Pulido et al, 2012). Moreover, dead thalli may represent a substrate for the settlement of crustose coralline algae (CCA) that cover small parts of some thalli.…”

Species interactions can shift the response of a maerl bed community to ocean acidification and warming

Abstract. Predicted ocean acidification and warming are likely to have major implications for marine organisms, especially marine calcifiers. However, little information is available on the response of marine benthic communities as a whole to predicted changes. Here, we experimentally examined the combined effects of temperature and partial pressure of carbon dioxide (pCO 2 ) increases on the response of maerl bed assemblages, composed of living and dead thalli of the free-living coralline alga Lithothamnion corallioides, epiphytic fleshy algae, and grazer species. Two 3-month experiments were performed in the winter and summer seasons in mesocosms with four different combinations of pCO 2 (ambient and high pCO 2 ) and temperature (ambient and +3 • C). The response of maerl assemblages was assessed using metabolic measurements at the species and assemblage scales. This study suggests that seasonal variability represents an important driver influencing the magnitude and the direction of species and community response to climate change. Gross primary production and respiration of assemblages was enhanced by high pCO 2 conditions in the summer. This positive effect was attributed to the increase in epiphyte biomass, which benefited from higher CO 2 concentrations for growth and primary production. Conversely, high pCO 2 drastically decreased the calcification rates in assemblages. This response can be attributed to the decline in calcification rates of living L. corallioides due to acidification and increased dissolution of dead L. corallioides. Future changes in pCO 2 and temperature are likely to promote the development of non-calcifying algae to the detriment of the engineer species L. corallioides. The development of fleshy algae may be modulated by the ability of grazers to regulate epiphyte growth. However, our results suggest that predicted changes will negatively affect the metabolism of grazers and potentially their ability to control epiphyte abundance. We show here that the effects of pCO 2 and temperature on maerl bed communities were weakened when these factors were combined. This underlines the importance of examining multifactorial approaches and community-level processes, which integrate species interactions, to better understand the impact of global change on marine ecosystems.
