A urbanização nas zonas costeiras torna necessário avaliar o impacto antrópico sobre os ecossistemas associados. O objetivo deste trabalho foi analisar temporalmente a dinâmica de populações de macroalgas com potencial bioindicador, estabelecendo-as como ferramenta para avaliação da saúde ambiental. Foi amostrado o ambiente recifal intertidal da Praia de Formosa, no Município de Cabedelo, Estado da Paraíba, Nordeste do Brasil, durante intervalos trimestrais de agosto/2013 a novembro/2014. A variação temporal da frequência de ocorrência (F') das populações macrofitobênticas foi avaliada pela análise de variância (One-Way Anova) com teste Post-Hoc de Tukey. A influência das variáveis ambientais sobre F’ foi avaliada pela Correlação Linear de Pearson e pela PERMANOVA. A análise da qualidade ambiental e a proposta de biomonitoramento basearam-se no Grupo 1, formado por espécies perenes e/ou raras com maiores valores ao longo do Componente Principal 1 (CP1) da Análise de Componentes Principais (ACP), e Grupo 2, formado por espécies com comportamento errático com menores valores ao longo do CP1 da ACP. Foram encontradas 33 espécies macrofitobênticas. A frequência de ocorrência apresentou variação temporal, porém não influenciada pelo conjunto de variáveis ambientais. Phyllodictyon anastomosans, Gelidiella acerosa e Gelidium corneum compuseram o Grupo 1, com Dictyopteris delicatula, Canistrocarpus cervicornis e Hypnea spinella formando o Grupo 2. O Grupo 2 apresentou correlação positiva com a temperatura, alcançando as máximas frequências nos períodos mais quentes, mas esse fator isolado não é capaz de explicar a distribuição errática das espécies. A ocorrência de espécies bioindicadoras de eutrofização foi considerada natural, fato que, aliado à alta frequência de espécies bioindicadoras de qualidade ambiental, sugerem que o Recife de Formosa não sofre impactos antrópicos significativos. O desaparecimento de espécies perenes ou crescimento populacional significativo de espécie rara (Grupo 1), bem como a fuga do padrão temporal de frequência ou dominância do recife pelas espécies do Grupo 2, são indícios da ocorrência de impactos. Este trabalho fornece à gestão do Recife de Formosa uma eficiente ferramenta para avaliação do impacto urbano sobre a comunidade macrofitobêntica.

This paper reports on the defensive chemical properties of the marine tropical brown seaweed Canistrocarpus cervicornis against herbivory. A natural concentration of dichloromethane crude extract (DCE) obtained from this seaweed significantly inhibited feeding by the sea urchin Lytechinus variegatus. The major metabolite isolated from this active DCE extract was identified as the (4R,7R,14S)-4α,7α-diacetoxy-14-hydroxydolast-1(15),8-diene that strongly inhibited feeding by the same sea urchin. This result suggests that the dolastane diterpenes class may constitute the defensive system of C. cervicornis against herbivory, and probably also of that of other brown seaweeds endowed with a biosynthetic pathway capable of producing compounds of the dolastane-type, a typical skeleton found in Dyctioteae species worldwide. This is the first report showing this compound-type (dolastane diterpenes) as a chemical defense against herbivory in marine seaweeds. This study constitutes an additional report broadening the known spectrum of action and roles of secondary metabolites of the C. cervicornis and Dyctioteae species.

Feeding Grounds

Macroalgal beds are recognised for their role as nursery and feeding grounds for several marine species. This study was conducted in the Tamandaré reef complex within the limits of the Costa dos Corais Marine Protected Area (MPA), North-eastern Brazil. The macroalgal bed studied is subjected to several disturbances, especially from tourism. The reef fish were assessed with free dives during the day and night using visual censuses within transects (20 × 2 m) and random swims. The percentage algal cover was estimated using quadrats (40 cm2). The behavioural traits of the fish also provided an understanding of their habitat use. In total, 68 fish species were recorded. The most abundant species were representatives of the families Labridae, Pomacentridae, Acanthuridae and Haemulidae. Sargassum polyceratium, Dictyopteris delicatula and Canistrocarpus cervicornis were the most abundant macroalgae. Because the most abundant fish trophic guild included primarily mobile invertebrate feeders (41.8%) and carnivores (28.4%), it is suggested that the high-canopy macroalgae harbour epiphytic invertebrates, which these fish use for food. Thereby, the study area would act as important nursery and feeding grounds. Tourism activity (e.g. laying chairs, trampling and anchoring) may disrupt fish behaviour and life- history traits and result in damage that would require mitigation through environmental awareness and law enforcement in the most affected areas.
