In this article, the authors examined the relationship between zooplankton community dynamic and important biotic factors, such as predation and food availability, in Jakarta bay, from July to November 2009.Abstract:
The dynamics in zooplankton abundance were regulated by changes in water physical-chemical parameters and interaction with biotic factors. In this research we examined the relationship between zooplankton community dynamic and important biotic factors, such as predation and food availability, in Jakarta bay. Plankton samplings were done in 10 sampling stations in Jakarta bay, from July to November 2009. Zooplankton samples were collected using horizontal towing method with NORPAC plankton net (mesh size 300 μm). Salinity, water depth, water temperature, and water transparency were measured. Phytoplankton samples were also collected with the same method as zooplankton, using Kitahara plankton net (mesh size 80 μm). Zooplankton taxas were grouped into two groups, the prey and predatory zooplankton. The results showed that there were two different patterns in zooplankton groups dynamic i.e., the single and double peak. The abundance peak in most zooplankton groups, such as copepods, cirripeds, luciferids, and tunicates, were induced by the high food availability during the phytoplankton bloom in August. The high abundance of prey zooplankton groups in August was responded by the predatory zooplankton groups, resulting in high abundance of predatory zooplankton in adjacent month. The high abundance of ctenophores and chordates (fish larvae) were suggested as the main factor for the low abundance of other zooplankton in September. Physical and chemical factors were not the regulating factors due to the stability of those factors during this research period. Thus we concluded that food availability and predator-prey interaction were the main factors which regulate zooplankton community dynamics in Jakarta bay.

The Seasonal Distribution of the Zooplankton off Chicken Key in Biscayne Bay, Florida
TL;DR: This investigation was undertaken to determine the nature and seasonal distribution of the zooplankton community at a single station off Chicken Key in Biscayne Bay, Florida, and seasonal data on the water temperature, salinity and rainfall were obtained.

Changes in plankton community structure and function in response to variable freshwater flow in two tributaries of the Chesapeake Bay
TL;DR: In this paper, the potential for copepod control of microzooplankton biomass in the dry and wet years was evaluated by comparing the estimated grazing rates of micro-plankton by the dominant copepOD species (Acartia spp. and Eurytemora affinis) to micro-phytoplankton growth rates and by calculating the percent of daily micro-zooplanton standing stock removed through copepoder grazing.

TL;DR: The logistic regression proved to be a useful approach for predicting the occurrence of species under varying environmental conditions at a local scale and can be considered of reasonable application (and should be tested in other estuarine systems) due to its ability to predict the occurrences of individual zooplanktonic species associated with habitat changes.
