The main conclusions of this study are that 1) there is a very tight coupling between air and water
temperatures in Dutch shallow lakes, irrespective of their size, resulting in highly similar patterns of lake temperature and a direct
translation of climate warming into lake warming; 2) on average water temperature has increased by 2 °C in the period 1961–2006; 3)
temperature patterns in the tidal inlet showed a surprising resemblance with the lake temperature patterns, the coastal marine system
essentially behaving like an extremely large lake; 4) there are, however, strong seasonal patterns in the extent of warming in a given
period of the year; 5) lake warming leads to ca. 3 weeks earlier onset of growth and 20mmlarger sizes in bream during 1971–2006 under
the assumption of temperature limited growth in these eutrophic ecosystems.
