Growth and abundance of Synechococcus sp. in a Mediterranean Bay: seasonality and relationship with temperature

In this study, we confirm the relationship between temperature and Synechococcus sp. experimental growth rates (r = 0.87, p 30%, of the total gross autotrophic production and >20% of the total autotroph~c blomass in summer Thus, Sj~nechococcus is an important source of organic C and nutrients for the coastal Mediterranean food web in the summer.
