Spatial and nycthemeral distribution of the zooneuston off Fernando de Noronha, Brazil

open access: yesBrazilian Journal of Oceanography, 2014
Island environments drastically modify the hydrodynamics of ocean currents and generate strong vertical turbulence. This leads to an upward transport of nutrient-rich waters, thus increasing the biomass of plankton in these oceanic marine environments ...

Horizontal and vertical distribution of mesozooplankton species richness and composition down to 2,300 m in the southwest Atlantic Ocean

open access: yesZoologia (Curitiba), 2014
We describe the species richness, distribution and composition of mesozooplankton over the continental shelf and slope, and in the water masses in the Campos Basin, southwest Atlantic Ocean. We analyzed the mesozooplankton from two oceanographic cruises (

The Chaetognatha of the Inshore Waters of North Carolina1 [PDF]

open access: yesLimnology and Oceanography, 1958
Plankton samples were taken along the coast and in the sounds of North Carolina to determine the inshore distribution of the Chaetognatha. Five species were found within ten miles of the coast. The large northern sounds with water of reduced salinity do not appear to support an appreciable chaetognath population. Sagitta hispida and S.

Studies on chaetognaths off Ubatuba region, Brazil: II. Feeding habits

open access: yesBrazilian Journal of Oceanography, 1995
The diet of chaetognath species were studied by examining the gut contents of 9466 specimens collected off Ubatuba region, São Paulo State. The greatest proportion of chaetognaths (7119 individuals) showed their gut contents empty. Copepods, mollusc eggs,

Pteropoda, Cladocera, and Chaetognatha associations as hydrological indicators in the southern Brazilian Shelf Asociaciones de Pteropoda, Cladocera y Chaetognatha como indicadores hidrológicos de la plataforma del extremo sur de Brasil

open access: yesLatin American Journal of Aquatic Research, 2008
Associations of pteropod, cladoceran, and chaetognath species were analyzed for the southern coast of Brazil in order to present a biological diagnosis of the oceanographic conditions in winter and summer. The density data from the different species were
