Abstract The photosynthetic activities of benthic diatoms in response to temperature changes were assessed by measuring chlorophyll
fluorescence kinetics. Small benthic diatom species with large surface area to volume (SA/V) ratios responded to increasing temperature differently from large diatoms, since larger ratios caused lower photosynthetic
activity under high-temperature conditions. The small SA/V ratios of large cells may be advantageous in benthic environments under adverse conditions such as high temperature and/or
strong light. A size-dependent differential response of benthic diatoms to changes in environmental factors such as temperature
may result in an altered distribution of the different diatom communities.
