Micro- and mesozooplankton were studied in the Sergipe estuary, northeastern Brazil, in order to assess the temporal variability in abundance and biodiversity under stressed conditions (urban pollution). Zooplankton samples and abiotic data were collected at one station during a full tidal cycle in July 2001 and in February 2002, corresponding to the rainy and dry seasons, respectively. The salinity regime was euhaline-polyhaline. Phosphate and dissolved oxygen were higher in July 2001, and…

Short-term variation of plankton spatial distribution at a subtropical mixed estuarine system.
The results demonstrate how variable the estuarine plankton horizontal structure can be over short time-scales even in mixedEstuarine systems under relatively homogeneous conditions, highlighting the importance to consider such temporal scales for a more accurate understanding of the dynamics of these communities.
5 years of monitoring of zooplankton community dynamics in a newly impounded sub-tropical reservoir in Southeast Asia (Nam Theun 2, Lao PDR)
The zooplanktonic community of the Nam Theun 2 Reservoir, newly impounded, located in Lao PDR was monitored from 2009 to 2013. Five sampling stations distributed on the surface of the reservoir were
Zooplankton Fluctuations in the Surface Waters of the Estuary of a Large Subtropical Urban River
The Danshuei River has a third largest catchment area and third longest in Taiwan. It flows through the capital, Taipei, and more than six million people live within its catchment area. Its estuary
The impact of sewage on environmental quality and the mesozooplankton community in a highly eutrophic estuary in Argentina
Eutrophication caused by human sewage is a growing phenomenon along coasts. Mesozooplankton abundance, community structure, and environmental quality were compared at two sites in the inner Bahia
Copepod Assemblage Dynamics in a Snowmelt-Dominated Estuary
What limits secondary production in the estuaries of snowmelt-dominated basins? Due to substantial differences in their annual hydrographs, zooplankton dynamics in these estuaries are expected to

Comparison of zooplankton community structure between impacted and non-impacted areas of Paranaguá Bay Estuarine Complex, south Brazil
We analysed the seasonal distribution of the zooplankton community in an anthropogenically impacted area (Paranaguá Bay) and a non-impacted area (Laranjeiras Bay) of the Paranaguá Bay Estuarine
Change and recovery of coastal mesozooplankton community structure during the Deepwater Horizon oil spill
The response of mesozooplankton community structure to the Deepwater Horizon oil spill in the northern Gulf of Mexico was investigated using data from a long-term plankton survey off the coast of


Diel and seasonal changes in the macrozooplankton community of a tropical estuary in Northeastern Brazil
There was a large stochastic variation between samples, and a regular temporal zooplankton cycle was not observed, so the rainy season presented greater numerical abundance.
Mesozooplankton of an Impacted Bay in North Eastern Brazil
As a whole, Suape Bay has been under severe environmental stress and it seemed reasonable to assume that the recent modifications of the basin have resulted in changes in species composition and trophic structure, with an increase in marine influence.
Zooplankton Distribution in the Guaraú River Estuary (South-eastern Brazil)
Abstract The structure and seasonal variability of zooplanktonic associations were analysed over a 1-year period in the Guarau River Estuary (south-east Brazil). The spatial segregation of the
Geographical and seasonal variations in taxonomic composition, abundance and biomass of microzooplankton across a brackish-water lagoonal system of Japan
The taxonomic composition, abundance and biomass of microzooplankton were studied at eight stations in Lake Shinji-Ohashi River-Lake Nakaumi brackish-water system, Japan, monthly from April 1998 to March 1999, with marked seasonal variations, being higher in spring and summer than in the remaining seasons.
Spatial and temporal distribution in density and biomass of two Pseudodiaptomus species (Copepoda: Calanoida) in the Caeté river estuary (Amazon region--North of Brazil).
The results showed that the contribution of P. richardi for the secondary production in the Caeté River Estuary is more important in the limnetic zone than in other zones where euhaline-polyhaline regimes were predominant.
Micro- and mesozooplankton response to enhanced nutrient input – a mesocosm study
It is concluded that enhanced nutrient input affected both biomass and the relative species composition of the zooplankton community.
The planktonic food web structure of a temperate zone estuary, and its alteration due to eutrophication
Results indicated that although current nitrogen and other nutrient loadings into the estuary are much higher than past inputs, the average concentration of dissolved inorganic nutrients is similar (though slightly higher) to past values, and relative proportioning among chemical species does vary from west to east.
Short-term changes in the mesozooplanktonic community in the Seine ROFI (Region of Freshwater Influence)(eastern English Channel)
Discrete-depth, hourly mesozooplankton samples were collected over a 92 h period in May 1992 at an anchor station within the Seine Region of Freshwater Influence (ROFI) (English Channel). The
Tintinnids and other microzooplankton — seasonal distributions and relationships to resources and hydrography in a Maine estuary
Species composition and abundance of tintinnids and other microzooplankton were studied in the Damariscotta River estuary, Maine, USA during the period March 1981 to May 1982 and Spearman rank correlation coeffi- cients indicated that temperature, nanoplankon chlorophyll and phaeopigments passing a 20 jun filter were important factors correlating with total tintinnid density.
Mesozooplankton grazing under conditions of extreme eutrophication in Guanabara Bay, Brazil
The results suggest that grazing was not a controlling process for the nano- and microplankton community in the study area, and dinoflagellates were an important group for mesozooplankton nutrition, being ingested in significant amounts during all experiments.
