| Zusammenfassung |
| Four strains of the coccolithophore E. huxleyi (RCC1212, RCC1216, RCC1238, RCC1256)
were grown in dilute batch culture at four CO2 levels ranging from
~200 μatm to ~1200 μatm. Growth rate, particulate
organic carbon content, and particulate inorganic carbon content were
measured, and organic and inorganic carbon production calculated. The four
strains did not show a uniform response to carbonate chemistry changes in
any of the analysed parameters and none of the four strains displayed a
response pattern previously described for this species. We conclude that the
sensitivity of different strains of E. huxleyi to acidification differs substantially
and that this likely has a genetic basis. We propose that this can explain
apparently contradictory results reported in the literature. |
