... Water temperature stands as another pivotal factor influencing the distribution and abundance of mesozooplankton, given that all metabolic rates of mesozooplankton are temperature dependent (Heinle, 1969;Mauchline, 1998), primarily associated with seasonal variability. Thus, horizontal gradients of temperature also play a role in shaping the spatial partitioning of mesozooplankton within estuaries (Bollens et al., 2011;Wooldridge and Deyzel, 2012). ...

... The massive blooms of the two raphidophytes species Chattonella antiqua and Heterosigma akashiwo might offer extra evidence as effective biological elements in evaluating responses to eutrophication since close connection of H. akashiwo blooming was found with increased load of DIN and DIP in agreement with others [55]. The presentrecorded bloom periods of different species from different classes and of different magnitudes provided important indicators of degraded water quality [56]. The major part of Chl. a production occurred with the massive summer phytoplankton bloom representing a strong indicator of heavy eutrophication and trophic state [56]. ...
