“…O. longicauda, F. borealis, O. fusiformis, and O. rufescens were dominant in Toyama Bay, Japan (Tomita et al, 2003). O. dioica and O. cophocerca were found in the Macaé River estuary by Beltrão (2003 (Tundisi, 1970;Lopes et al, 1998;Esnal, 1999;Campos, 2000;Shiganova, 2005;Bonecker and Carvalho, 2006). The second species in terms of overall abundance was O. rufescens.…”

“…O. dioica was the most abundant species in the coastal stations. This species is highly adapted to the spatial gradient of salinity and variations in the concentration of particulate matter (Tundisi, 1970). In the estuary stations, O. rufescens reached its highest densities.…”

“…O. rufescens, O. dioica, and O. cophocerca showed their peaks of density in the dry season. O. rufescens was also more abundant in the dry season (Campos, 2000), but it was more abundant in the rainy season as well (Tundisi, 1970). O. dioica reached a peak of density between December and March in the rainy season (Esnal et al, 1985).…”

“…Appendicularians are numerically well represented, after the Copepoda, in coastal and estuarine environments. Studies on the distribution, specific composition, and abundance of appendicularians in oceanic regions of the southwest Atlantic have been carried out by several investigators, e.g., Lohmann (1896Lohmann ( , 1931, Lohmann and Buckmann (1926), Hentschell (1939), Fenaux (1967), Björnberg and Forneris (1956a, 1956b, 1958, Forneris (1965), Tundisi (1970), Esnal (1999), Campos (2000), and Bonecker and Carvalho (2006). Some studies have been carried out in coastal regions, where only species of the family Oikopleuridae (Bonecker et al, 1991;Vega-Pérez, 1993;Bonecker et al, 1998;Dias et al, 1999;Biancalana et al, 2005).…”

This study aimed to identify and assess the seasonal and spatial variations of the appendicularians in the CaravelasRiver estuary and the adjacent coastal area. Samples were taken during 12 campaigns over five years (2001 and 2003-2006). Ten species were identified; the most abundant were Oikopleura dioica, Oikopleura rufescens, and Oikopleura longicauda. These species represented more than 95% of the total numbers of appendicularians. The remaining species were less frequent and occurred in low densities. The mean density of appendicularians found at the coastal stations (804 ind.m -3. ) was higher than in the estuary (66 ind.m -3 ). However, the differences observed between the estuary and coastal stations were not significant (p=0.54). The samples taken during the dry season showed a higher mean density (587 ind.m -3 ) than in the rainy season (376 ind.m -3 ), and the differences between the seasons were statistically significant (p=0.004).

“…Nos ecossistemas estuarinos, o fitoplâncton é muito mais abundante que nas áreas costeiras e oceânicas, exatamente pelo fato de nos estuários o suprimento de nutrientes ser maior, em virtude da drenagem constante das águas dos rios e ciclagem dos resíduos orgânicos decorrente da decomposição da matéria orgânica (TUNDISI, 1970).…”

The present study aims to evaluate the environmental conditions of the Carrapicho River estuary (Itamaracá, PE, Brazil). Water samples were collected at three stations, monthly, from March/07 to February/08, using Niskin bottles on the surface at daytime low and high tide. The annual rainfall during the sampling period ranged from 25.6 to 390.8 mm; depth ranged from 2.6 to 25m; temperature ranged from 26 to 31°C; transparency ranged from 1.0 to 3.5 m; salinity ranged from 20.2 to 38.2; dissolved oxygen ranged from 2.2 to 6.2 ml/L; percentage of oxygen saturation ranged from 48.4 to 105.5%; pH ranged from 7.8 to 8.8; ammonia ranged from 0.01 to 0.16 µmol/L; nitrite ranged from 0.01 to 0.22 µmol/L; nitrate ranged from 0.06 to 12 04 µmol/L; phosphate ranged from 0.01 to 1.9 µmol/L; silicate ranged from 1.3 µmol/L to 47 µmol/L; suspended particulate matter ranged from 3 to 63 mg/L; A Chlorophyll ranged from 2.3 to 40 mg.m -3 . Carrapicho River was characterized as coastal plain, low sediment transport capacity. Its salinity regime varies from polyhaline to euhaline and still exempt from the process of eutrophication.Key words: estuarine zone, chlorophyll a, environmental variables. RESUMOO presente trabalho teve como objetivo principal avaliar as condições ambientais do estuário do rio Carrapicho (Itamaracá-Pernambuco-Brasil). As amostras de água foram coletadas em três estações, mensalmente, no período de março/07 a fevereiro/08, com garrafas de Niskin, na superfície, em baixa-mar e preamar diurnas. A pluviosidade anual durante o período amostrado variou de 25,6a 390,8mm; a profundidade de 2,6 a 25m; a temperatura variou de 26 a 31°C; a transparência de 1,0 a 3,5m; a salinidade de 20,2 a 38,2; o oxigênio dissolvido de 2,2 a 6,2 ml/L; o Palavras chave: zona estuarina, clorofila a, variáveis ambientais. INTRODUÇÃOOs ambientes estuarinos são regiões costeiras semi-fechadas nas desembocaduras dos rios, sujeitas aos aportes dos rios e do fluxo marinho. Os nutrientes transportados pelos rios e a rápida troca entre as águas de superfície e sedimentos contribuem para uma produtividade biológica extremamente alta, sendo considerado um dos ecossistemas mais produtivos da Terra. Essa alta produtividade resulta da regeneração rápida e local dos nutrientes bem como dos aportes destes pelos rios e marés. Sua importância se estende aos ecossistemas marinhos através da sua exportação líquida de matéria orgânica, organismos e detritos particulados e dissolvidos (RICKLEFS, 2003).
