Diurnal variation of zooplankton biochemical composition and biomass in plankton production tanks
The nutritional value of zooplankton (lipid and phosphorus contents) was analyzed in outdoor, plankton-culture tanks, to monitor the effects of diurnal variation and fertilization. Total lipid contents were significantly ...
Decadal change in zooplankton seasonal succession in the Bahía Blanca estuary, Argentina, following introduction of two zooplankton species
(Oxford University Press, 2004-12)
Seasonal zooplankton succession (mainly of the mesozooplankton) in the inner zone of Bahı ́a Blanca estuary during the period 1990–1991 was compared to that from the period 1979–1980 in order to detect changes having taken ...
Diurnal changes in zooplankton respiration rates and the phytoplankton activity in two Chilean lakes
(Kluwer Academic Publishers, 1989)
Respiration rates of natural zooplankton communities were measured for diel cycles in two lakes. Distinct diurnal cycles were observed in Embalse Rapel with high respiratory rates for the spring cladoceran dominated ...
Zooplankton community and tributary effects in free-flowing section downstream a large tropical reservoir
This study aimed to evaluate the zooplankton structures and environmental conditions in the interface reservoir-downstream river and tributaries. Zooplankton structure and environmental variables were analyzed in the ...
Zooplankton abundance variability in Magdalena Bay, Baja California Sur, Mexico (1997-2001)
(Latin American Journal of Aquatic Research, 2010)
Zooplankton ware studied from 16 oceanographic surveys carried out in Magdalena Bay, Baja California Sur, Mexico, between August 1997 and March 2001. Twenty-six taxonomic groups were identified, the most abundant and ...
