Many questions need to be addressed, e.g. Confidence in these models is limited by a lack of knowledge on several fronts, including data to constrain the choice of physiological parameters that differentiate the functional groups and identify all the biotic and abiotic factors that control primary production and community structure. Current community structure and primary production are predicted typically using simplistic phytoplankton growth models based on nutrient uptake kinetics for a limited number of nutrients, usually some combination of nitrogen, phosphorus, silicon and iron, for a limited number of functional groups of phytoplankton defined using a combination of taxonomy, cell size and biogeochemical function coupled with even more simplistic descriptions of their zooplanktonic predators ( Moore et al., 2002 Moore et al., 2004 Hood et al., 2006 Follows et al., 2007). Model predictions of climate-induced changes in phytoplankton community composition and primary and export production are in their infancy ( Anderson, 2005).

To improve predictions of marine ecosystem responses to environmental and climate change, plankton physiologists and ecologists need to determine how to quantify and parameterize the key physiological responses of plankton that will in turn affect marine food webs and the carbon-climate system. In aggregate, these stressors will modify phytoplankton community structure and have cascading consequences on marine food web dynamics and elemental cycling ( Beardall and Raven, 2004 Beardall and Stojkovic, 2006). Ocean acidification ( Raven et al., 2005a), ozone depletion and associated changes in UV-B in the upper water column ( Beardall and Raven, 2004 Beardall and Stojkovic, 2006), coastal eutrophication and other forms of pollution ( Ryther and Dunstan, 1971 Fanning, 1989 Smith et al., 1999 Rabalais et al., 2002), along with fishing pressure ( Myers and Worm, 2003 Worm et al., 2005) superimpose additional stresses on marine ecosystems. Climate change over the next century is expected to modify ocean ice cover, temperature, precipitation, and circulation ( Meehl et al., 2007), altering the environmental conditions that influence phytoplankton standing stock and primary production ( Sarmiento et al., 2004 Irwin and Finkel, 2008). Phytoplankton are currently responsible for ∼50% of global primary production ( Falkowski and Raven, 2007).
In turn, these changes are expected to have further impacts on phytoplankton community structure through as yet poorly understood secondary processes associated with trophic dynamics. This suggests that cell size and elemental stoichiometry are promising ecophysiological traits for modelling and tracking changes in phytoplankton community structure in response to climate change. A review of current literature indicates cell size and elemental stoichiometry often respond predictably to abiotic conditions and follow biophysical rules that link environmental conditions to growth rates, and growth rates to food web interactions, and consequently to the biogeochemical cycling of elements.
Resulting changes in phytoplankton community structure are expected to have a cascading effect on primary and export production, food web dynamics and the structure of the marine food web as well the biogeochemical cycling of carbon and bio-limiting elements in the sea.
