“…According to theory, small cells increase metabolic performance at high temperatures by providing sufficient surface area to transport substrates (Atkinson et al, 2006;Czarnoleski et al, 2013). Many ectotherms-including bacteria (Sjostedt et al, 2012), protists (Butler and Rogerson, 1996;Atkinson et al, 2003), rotifers (Stelzer, 2002, planarians (Romero and Baguna, 1991), nematodes (vanVoorhies, 1996), fish (vanVoorhies, 1996, lizards (Goodman and Heah, 2010), and flies (Partridge et al, 1994;Blanckenhorn and Llaurens, 2005)-develop smaller cells in warm constant environments. In such environments, demands for resources are high but supplies of oxygen are low (Woods, 1999;Atkinson et al, 2006).…”

Changes in cell size might be an important component of adaptation to thermal heterogeneity. Although Drosophila melanogaster develops smaller cells at fluctuating temperatures, we do not know whether this response depends on the frequency or amplitude of thermal change. In a laboratory experiment, we exposed flies to either frequent or infrequent fluctuations between 17 and 27 °C, while controlling the total exposure to each temperature. Flies emerged from these treatments with similar body sizes, but flies at more frequent fluctuations emerged earlier and had smaller epidermal cells for a given body size. Tissue built from small cells has more nuclei for transcription, shorter distances between cell compartments, and a larger surface area for transport across membranes. Therefore, we hypothesize that physiological effects of small cells reduce lags in metabolic activity and enhance performance of flies during warming. For plasticity of cell size to confer a fitness advantage, this hypothetical benefit must outweigh the cost of maintaining a greater area of plasma membrane.

“…The relatively large volumes found by us can in part be explained by the method of sample preparation; volumes determined by X‐ray microanalysis have been found to be 40% larger than those determined for fixed cells by fluorescence microscopy, as formaldehyde can cause shrinkage of bacterial cells (Fagerbakke et al ., ). In addition, the low in situ and incubation temperatures of the sediments used in this study may have led to larger than average cell volumes, as bacterial cell volume and temperature have been found to be negatively correlated (Sjöstedt et al ., ).…”

The stoichiometry of prokaryotes (Bacteria and Archaea) can control benthic phosphorus (P) fluxes relative to carbon (C) and nitrogen (N) during organic matter remineralization. This paper presents the first experimental data on benthic microbial stoichiometry. We used X-ray microanalysis to determine C : N : P ratios of individual prokaryotes from C-limited Baltic Sea sediments incubated under oxic or anoxic conditions. At approximately 400:1, C : P ratios of prokaryotes from both oxic and anoxic incubations were higher than the Redfield ratio for marine organic matter (106:1), whereas prokaryotic C : N ratios (6.4:1) were close to the Redfield ratio. We conclude that high microbial C : P ratios contribute to the enhanced remineralization of P from organic matter relative to C and N observed in many low oxygen marine settings.

“…Bacterial abundance and growth rate were positively correlated with increasing temperature in an earlier study (Shiah & Ducklow, ). Other reports also showed the effect of temperature on bacterial abundance, growth, and community structure (Crump & Hobbie, ; Hewson et al., ; Lee & Fuhrman, ; Pinhassi & Hagström, ; Pomeroy & Wiebe, ; Robinson, ; Sjöstedt et al., ). Sato‐Takabe et al.…”

“…Bacterial growth and respiratory rates show temperature dependence (Pomeroy & Wiebe, ; Robinson, ). In addition to biochemical responses, community structure also changes with temperature (Crump & Hobbie, ; Hewson, Steele, Capone, & Fuhrman, ; Lee & Fuhrman, ; Pinhassi & Hagström, ; Sjöstedt, Hagström, & Zweifel, ). Previous studies have shown that environmental conditions have varied effects on the population abundance of specific bacterial groups (Crump & Hobbie, ; Pinhassi & Hagström, ).…”

High temperature accelerates growth of aerobic anoxygenic phototrophic bacteria in seawater

Temperature is an important controlling factor in the growth activity of all microorganisms. Aerobic anoxygenic phototrophic (AAP) bacteria actively grow in the ocean and are known as one of the main driving forces in organic matter cycling in surface seawater environments. Whether temperature change affects AAP bacteria activity from an ecological viewpoint remains an open question. To date, no known studies have reported the effect of temperature change on AAP bacteria growth in the ocean. We here show that the growth rate of AAP bacteria exceeded that of other bacterial types at high water temperatures in the absence of grazers. The slope of the regression line of the net growth rate of AAP bacteria as a function of water temperature was the same as that for non-AAP bacteria at all temperatures (10, 20, and 30°C); however, when grazers were eliminated, it was 4.7 times higher than that of non-AAP bacteria. This result suggests that AAP bacteria are more responsive to water temperature increases than other bacteria and that AAP bacteria might become more dominant than other bacteria under elevated water temperatures.
