Estuarine Relationships Between Zooplankton Community Structure And Trophic Gradients, Gyung Soo Park, Harold G. Marshall
Estuarine Relationships Between Zooplankton Community Structure And Trophic Gradients, Gyung Soo Park, Harold G. Marshall
Biological Sciences Faculty Publications
Zooplankton and water quality parameters were investigated at eight mesohaline stations in the lower Chesapeake Bay and Elizabeth River from January through December 1994 to identify the changes of zooplankton community structure with increased eutrophication. The total micro- and mesozooplankton biomass decreased with the increase of eutrophication. However, the relative proportion of microzooplankton increased with increased eutrophication. Within highly eutrophied waters, the small oligotrichs (m) and rotifers dominated the total zooplankton biomass (as carbon). However, tintinnids, copepod nauplii and mesozooplankton significantly decreased with the increase of eutrophication. These patterns were consistent throughout the seasons and had significant relationships statistically. These …

Short Term Secondary Production And Population Dynamics Of Crustacea Rotifera In Three Different Biotops Of Neusiedler See (Austria), Nuray Emi̇r Akbulut
Turkish Journal of Zoology
This paper describes the population dynamic parameters of the two crustaceans Diaphanosoma mongolianum, Arctodiaptomus spinosus and four rotifer species which are Filinia longiseta, Hexartra mira, Brachionus angularis and Polyarthra vulgaris.
Community Structure Of Zooplanktonic Organisms In Lake Akşehir, Nuray Emi̇r Akbulut
Community Structure Of Zooplanktonic Organisms In Lake Akşehir, Nuray Emi̇r Akbulut
Turkish Journal of Zoology
In this study, the abundance and seasonal distribution of rotifer and crustacean zooplankton were examined. A negative correlation beetween rotifers and crustaceans in terms of their abundancy rates was observed. Copepods were most abundant and comprised 43.3 %; rotifers comprised 34 % and cladocerans comprised 22.6% of the total zooplanktonic organisms. Copepods were abundant in autumn whereas rotifers were abundant in spring and autumn but cladocerans were abundant in summer periods. Some zooplanktonic organisms recorded in all samples throughout the study period were Filinia, Hexarthra, Brachionus, Asplanchna, Keratella, Arctodiaptomus spinosus and Diaphanosoma lacustris.

The Diel Vertical Distribution Of Zooplankton In The Southeast Black Sea, Funda Erkan, Ali̇ Cemal Gücü, Julia Zagorodnyaya
Turkish Journal of Zoology
The diel changes in the vertical distribution of zooplankton in the southeast Black Sea were described in this study. The zooplankton were sampled using two different sampling methods throughout one day in October 1996 and July 1997 at the same station. The zooplankton counts, the length measurements and biomass estimates showed that the zooplankton in the southeast Black Sea is dominated by small organisms, among which Noctiluca scintillans is the dominant species. In the vertical distribution of zooplankton, three groups were observed in different layers. Calanus euxinus and Pseudocalanus elongatus showed a clear vertical migration pattern. Conventional measurements (settling volume, …
