“…Compared with the number of zooplankton species found in other tropical Brazilian reservoirs, the number of species recorded here is close to that observed in studies based on a few samples (Almeida et al, 2006;Leitão et al, 2006;Eskinazi-Sant'Anna et al, 2007;Melo Júnior et al, 2007). In such studies, sampling generally occurred a few times during the year, and long time intervals separated the samples.…”

“…In the Caatinga biome in particular, the semi-arid climate and the predominance of intermittent rivers and lakes could indicate low diversity among the aquatic biota, with few endemic species and a predominance of generalist, widespread species. However, the few studies available on the plankton of inland waters of the semi-arid region in other northeastern states show that this biome is not poor in species (e.g., Melo Júnior et al, 2007;Almeida et al, 2010;Moura et al, 2010).…”

The plankton fauna of the state of Piauí, Northeastern Brazil, especially in the Parnaíba basin, is still poorly known; the results of most studies of the subject have not been published and can only be found in grey literature (unpublished scientific works), such as course completion work and consulting reports. Thus, this paper presents data from samples taken recently from different water bodies in Piauí and represents the second study to be published on the region's zooplankton since the pioneering work of Spandl (1926). A total of 38 species were recorded, including 23 new occurrences of rotifers, 10 of cladocerans and 2 of copepods for the state of Piauí. The greatest richness was observed for the rotifers, of which the genus Brachionus must be highlighted, especially at the Joana reservoir. Among the crustaceans, the greatest richness was observed at the Bezerra reservoir, where cladocerans of the genus Bosmina were prominent. The rotifers Brachionus havanaensis Rousselet, 1911 and Filinia longiseta (Ehrenberg, 1834); the cladocerans Diaphanosoma spinulosum Herbst, 1967 and Moina micrura Kurz, 1874; and the copepods Notodiaptomus cearensis Wright, 1936 and Thermocyclops decipiens Kiefer, 1927 occurred in all or in most environments in which the respective groups were studied. The results presented here expand the taxonomic list of zooplankton for the state of Piauí, including a total fauna of 30 species of rotifers, 15 of cladocerans and 3 of copepods. The zooplankton richness was considered low in the studied reservoirs compared to other freshwater ecosystems from Northeastern Brazil; however, the few studies developed in the Parnaíba basin suggest that the diversity for these organisms should be higher.

“…The high number of detected taxa is even more intriguing, since the period examined in this study was inferior than most of surveys conducted at the Brazilian coast. This richness could be even greater if we consider that the pump suction is not one of the most widely used sampling equipments for qualitative analysis of zooplankton, even this technique being adequate for quantitative data at exactly depths (Melo Júnior et al, 2015). For example, a study using simultaneous plankton net (300 µm) at the same area (Schwamborn, R. unpublished data), recorded two genera of the complex Penaeus (Litopenaeus sp.…”

ABSTRACT. Composition changes of decapod larvae in a neotropical estuarine inlet (Catuama inlet, northeast Brazilian coast) were studied in a complete tidal cycle in August 2001. Sampling was performed at three stations at two or three depth levels that were located along a transect across the inlet. The collections were performed in 3 h intervals under a neap tide regime. Samples were taken with a pump and the water was filtered through 300 μm plankton net. 27 planktonic decapod taxa were identified, which included the first larval stages of the coastal and oceanic shrimps Lucifer faxoni and Acetes americanus, besides larvae of the estuarine and coastal decapods Pinnixa spp., Uca spp., Petrolisthes armatus, Upogebia spp. and Alpheidae, which were the most frequent taxa. All of the planktonic larval stages were observed for most of the decapods, suggesting that the probable exportation from the estuary is to the inner adjacent shelf area, instead of the outer oceanic area. Keywords: decapod larvae, meroplankton, tidal changes, neotropical estuary, northeastern Brazil.Composición de larvas de decápodos en la desembocadura de un estuario del noreste brasileño durante un ciclo completo de marea RESUMEN. Se analizaron los cambios en la composición de las larvas de decápodos en la desembocadura de un estuario neotropical durante un ciclo completo de marea en agosto de 2001. Las colectas se realizaron en 3 estaciones, en dos o tres profundidades, localizadas en una transecta interior. Los muestreos se realizaron a intervalos de 3 h durante la marea de cuadratura. Las muestras se colectaron con una bomba y se filtraron a través de una red de plancton (300 μm). Se identificaron 27 taxa de larvas de decápodos, incluyendo el primer estadio larval de los camarones costeros y oceánicos Lucifer faxoni y Acetes americanus, seguidos de las larvas de los decápodos estuarinos y costeros Pinnixa spp., Uca spp., Petrolisthes armatus, Upogebia spp. y Alpheidae, que fueron los taxa más frecuentes. Se observaron todos de los estadios larvales de la mayoría de los decápodos, lo que sugiere que probablemente la exportación del estuario es hacia el área interior de la plataforma adyacente, en vez de hacia el área oceánica exterior. Palabras clave: larvas de decápodos, meroplancton, cambios de marea, estuario neotropical, noreste de Brasil.
