“…The macrofauna associated to those meadows is dominated by the gastropod Tricolia affinis (Alves, 1991). Beyond the reefs, calcareous green algae (Halimeda sp) are abundant, originating a calcareous gravel bottom (Kempf, 1970). …”

Palavras chave: Copepoda, alimentação, peixes, teia trófica, estuário ABSTRACTMany economical and ecological important estuarine fishes are common in the artisan fisheries at the Santa Cruz Channel (Itamaracá -Brazil). Studies about fishes feeding emphasized the Copepoda as they are important to assess the throphic web interactions. Samples were monthly collected along Santa Cruz Channel with a seine net, from 1995 to 1998, besides data published since 1979. Fishes stomach content were analysed under a compound microscope and stereomicroscope. The fishes species that Copepoda were registered in the stomach content were: Opisthonema oglinum (Oithona spp. -40%), Citharichthys spilopterus (Parvocalanus crassisrostris -18%; Oithona spp. -5%; Calanopia americana -8%), Symphurus plagusia (Parvocalanus crassisrostris -20%, Euterpina acutifrons -5% and Acartia lilljeborgi -5%, Oithona spp. -5%); Eugerres brasilianus and Diapterus auratus (Macrosetella gracilis -6%, Farranula gracilis -3%, Acartia lilljeborgi -10%, Euterpina acutifrons -3% and Oncaea sp.-3%). Copepoda nauplii, eggs and carapace from non identified copepod species were also commonly registered. It was observed that planktonic Copepoda was a frequent food item to many fish species in the Santa Cruz Channel.

Este trabalho representa o início do levantamento sistemático das espécies de hidróides que ocorrem na Costa do Estado de Pernambuco, Brasil. São 11 espécies coletadas na plataforma continental, por uma Expedição realizada pela Superintendência de Desenvolvimento do Nordeste (SUDENE), em colaboração com o Laboratório de Ciências do Mar (LACIMAR), da Universidade Federal de Pernambuco.

“…Along the coast of Paraíba, Pernambuco and Alagoas, H. wrightii meadows are found from the intertidal zone to a depth of 10 m and are established mainly in areas protected by beach rocks or coral reefs on both soft and hard substrates (KEMPF, 1970;LABOREL-DEGUEN, 1963;FRANÇA et al, 2014). H. decipiens is generally found in association with H. wrightii, but in calm and protected areas with muddy sediment between 30 cm and 40 m depth (KEMPF, 1970;LABOREL-DEGUEN, 1963). H. baillonis occurs together with H. wrightii and H. decipiens in areas protected by reefs with strong turbidity and up to 3 m depth (MAGALHÃES et al, 2015).…”

Seagrass and Submerged Aquatic Vegetation (VAS) Habitats off the Coast of Brazil: state of knowledge, conservation and main threats

et al. 2016

Financial Support: This study was supported by the Brazilian Network for Coastal Benthic Studies -ReBentos (Programa SISBIOTA), Rede CLIMA and INCT for Climate Changes; sponsored by CNPq and FAPESP. Seagrass meadows are among the most threatened ecosystems on earth, raising concerns about the equilibrium of coastal ecosystems and the sustainability of local fisheries. The present review evaluated the current status of the research on seagrasses and submerged aquatic vegetation (SAV) habitats off the coast of Brazil in terms of plant responses to environmental conditions, changes in distribution and abundance, and the possible role of climate change and variability. Despite an increase in the number of studies, the communication of the results is still relatively limited and is mainly addressed to a national or regional public; thus, South American seagrasses are rarely included or cited in global reviews and models. The scarcity of large-scale and long-term studies allowing the detection of changes in the structure, abundance and composition of seagrass habitats and associated species still hinders the investigation of such communities with respect to the potential effects of climate change. Seagrass meadows and SAV occur all along the Brazilian coast, with species distribution and abundance being strongly influenced by regional oceanography, coastal water masses, river runoff and coastal geomorphology. Based on these geomorphological, hydrological and ecological features, we characterised the distribution of seagrass habitats and abundances within the major coastal compartments. The current conservation AbstrActPradarias de gramas marinhas e vegetação aquática submersa (VAS) estão entre os ecossistemas mais ameaçados do planeta, gerando preocupação sobre o equilíbrio dos ecossistemas costeiros e a sustentabilidade das pescarias. A presente revisão avaliou o estado do conhecimento sobre as pradarias marinhas e VAS do Brasil, considerando as respostas das plantas às condições ambientais, e o possível papel da geomorfologia costeira e variabilidade climática sobre a distribuição e abundância das populações. Apesar do crescente aumento no número de publicações, a comunicação dos resultados ainda é relativamente limitada e destina-se principalmente ao público nacional ou regional. Como resultado, as pradarias de gramas marinhas da América do Sul raramente são incluídas ou citadas em revisões e modelos globais. A escassez de estudos em larga escala e de longo prazo, permitindo a detecção de mudanças na estrutura, abundância e composição dos habitats e espécies associadas, limita a investigação das comunidades no que diz respeito aos efeitos potenciais das mudanças climáticas. Pradarias marinhas e VAS ocorrem ao longo de toda a costa brasileira, mas a distribuição e abundância das espécies são influenciadas pela oceanografia regional, massas de água costeiras, descarga de rios e geomorfologia costeira. Com base nas características oceanográficas, geomorfológicas, hidrológicas e ecológicas, o estudo discutiu a distr...
