Spatial and Temporal Variation in Copepod Community in the Helleh River Estuary – South Coast of Iran, Persian Gulf
Copepods are the main zooplankton assemblages in most tropical and semi-tropical estuaries. In this research, copepod population dynamics were investigated in Helleh River estuary, Persian Gulf during four seasons beginning from summer 2011 to spring 2012. Samples were taken using plankton net with mesh size of 140 µm and vertical towing from 5 fixed-stations in mid-season. Results showed that...
متن کاملBiochemical composition of wild copepods, Acartia spinicauda and Oithona similis, from Parangipettai coastal waters in relation to environmental parameters.
Percentage composition of protein, lipid, carbohydrate and amino acids of copepods, Acartia spinicauda and Oithona similis collected from Parangipettai coastal waters were estimated following standard methodologies. Of the principal biochemical constituents, protein formed the major component followed bylipid and carbohydrate. Biochemical composition analysis of wild copepods indicated their nu...
متن کاملMicrophagous ciliates in mesohaline Chesapeake Bay waters: Estimates of growth rates and consumption by copepods
Growth rates of microphagous ciliates (forms which feed primarily on picoplankton-sized prey) were estimated, along with rates of their consumption by copepods, in shipboard experiments conducted in the mesohaline portion of Chesapeake Bay, USA, under contrasting water column conditions in April, June, and August 1987. Estimates were based on temporal changes in cell densities in size-fractiona...

متن کاملDiel vertical migration and spatial overlap between fish larvae and zooplankton in two tropical lakes, Brazil.
The effect of fish larvae on the diel vertical migration of the zooplankton community was investigated in two tropical lakes, Finado Raimundo and Pintado lakes, Mato Grosso do Sul State, Brazil. Nocturnal and diurnal samplings were conducted in the limnetic region of each lake for 10 consecutive months from April 2008 to January 2009. The zooplankton community presented a wide range of response...
