Abstract The dwarf seagrass Zostera noltii is an
important primary producer in Atlantic coastal eco-
systems from Mauritania to southern Norway and the
Mediterranean Sea. Sessile intertidal organisms exist-
ing at the interface between marine and terrestrial
environments may be particularly vulnerable to
environmental change. In this study, we asked how
near to thermal tolerance limits natural populations of
Z. noltii are in the Ria Formosa coastal lagoon system
in southern Portugal. We recorded the maximum
temperatures in the Ria Formosa during the 2007
summer, and conducted experiments to determine the
