Use of intertidal areas by shrimps (Decapoda) in a brazilian Amazon estuary
The present work investigated the occupation and the correlation of the shrimp abundance in relation to environmental variables in different habitats (mangroves, salt marshes and rocky outcrops) in an Amazon estuary.

The collections were made in August and November 2009, at low syzygy tide on Areuá Beach, situated in the Extractive Reserve of Mãe Grande de Curuçá, Pará, Brazil totaling 20 pools. In each environment, we recorded the physical-chemical factors (pH, salinity, and temperature) and measured the area (m²) and volume (m³) of every pool through bathymetry. The average pH, salinity, temperature, area and volume of tide pools were 8.75 (± 0.8 standard deviation), 35.45 (± 3), 29.49 °C (± 2.32), 27.41 m² (± 41.18), and 5.19 m³ (± 8.01), respectively. We caught a total of 4,871 shrimps, distributed in three families and four species: Farfantepenaeus subtilis (98.36%) (marine) followed by Alpheus pontederiae (0.76%) (estuarine), Macrobrachium surinamicum (0.45%) and Macrobrachium amazonicum (0.43%) predominantly freshwater. The species F. subtilis and A. pontederiae occurred in the three habitats, whereas M. surinamicum occurred in salt marsh and rocky outcrop and M. amazonicum only in marisma. Temperature and pH were the most important environmental descriptors that significantly affected the density and biomass of shrimps. O presente trabalho investigou a ocupação e a correlação da abundância de camarões em relação às variáveis ambientais nos diferentes habitats (manguezal, marisma e afloramento rochoso) em um estuário amazônico. As coletas foram realizadas em agosto e novembro de 2009, na maré baixa de sizígia na praia do Areuá, situada na RESEX Mãe Grande de Curuçá, Pará, totalizando 20 poças. Em cada ambiente foram registrados os fatores físicoquímicos (pH, salinidade e temperatura) e mensuradas a área (m²) e o volume (m³) de cada poça através da técnica de batimetria. A média do pH, salinidade, temperatura, área e volume das poças-de-maré foram 8,75 (± 0,8 desvio padrão) 35,45 (± 3), 29,49 °C (± 2,32), 27,41 m² (± 41,18) e 5,19 m³ (± 8,01), respectivamente. Foi capturado um total de 4.871 indivíduos, distribuídos em três famílias e quatro espécies: Farfantepenaeus subtilis (marinha) a mais frequente (98,36%), seguida de Alpheus pontederiae (0,76%) (estuarina), Macrobrachium surinamicum (0,45%) e Macrobrachium amazonicum (0,43%) predominantemente dulcícolas. As espécies F. subtilis e A. pontederiae ocorreram nos três habitats, enquanto que M. surinamicum ocorreu no afloramento rochoso e marisma e M. amazonicum somente no marisma. O pH e a temperatura foram os descritores ambientais mais importantes que afetaram significativamente a densidade e a biomassa dos camarões. 2015-04-10T16:07:49Z 2015-04-10T16:07:49Z 2014-03 Artigo de Periódico SAMPAIO, HEBERT A.; MARTINELLI-LEMOS, JUSSARA M.

The present work investigated the occupation and the correlation of the shrimp abundance in relation to environmental variables in different habitats (mangroves, salt marshes and rocky outcrops) in an Amazon estuary. The collections were made in August and November 2009, at low syzygy tide on Areuá Beach, situated in the Extractive Reserve of Mãe Grande de Curuçá, Pará, Brazil totaling 20 pools. In each environment, we recorded the physical-chemical factors (pH, salinity, and temperature) and measured the area (m²) and volume (m³) of every pool through bathymetry. The average pH, salinity, temperature, area and volume of tide pools were 8.75 (± 0.8 standard deviation), 35.45 (± 3), 29.49 °C (± 2.32), 27.41 m² (± 41.18), and 5.19 m³ (± 8.01), respectively. We caught a total of 4,871 shrimps, distributed in three families and four species: Farfantepenaeus subtilis (98.36%) (marine) followed by Alpheus pontederiae (0.76%) (estuarine), Macrobrachium surinamicum (0.45%) and Macrobrachium amazonicum (0.43%) predominantly freshwater. The species F. subtilis and A. pontederiae occurred in the three habitats, whereas M. surinamicum occurred in salt marsh and rocky outcrop and M. amazonicum only in marisma.
