“…Our results also support suggestions that stressful high temperatures may lead to decreases in cellular PIC / POC ratios and calcification (De Bodt et al, 2010;Feng et al, 2017;Gerecht et al, 2014;Krumhardt et al, 2017). The cellular PIC / POC ratio of E. huxleyi was much more plastic than the other ratios we measured, including TPC / PON and POC/PON.…”

“…Thermal variation treatments transiently but repeatedly experienced the extreme high temperature point (28 • C), leading to extremely low calcification rates and PIC contents and thus relatively low PIC / POC and Cal / Photo ratios. Previous E. huxleyi studies agree that high temperature decreases PIC content, PIC / POC ratios and Cal / Photo ratios (Feng et al, 2017;Gerecht et al, 2014). The two different patterns of responses to thermal variation we observed under low and high temperatures imply a seasonal pattern in the ways that thermal variations will affect the elemental stoichiometry of E. huxleyi .…”

“…The effect of temperature on E. huxleyi cellular PIC / POC ratio is, however, more complex. De Bodt et al 2010and Gerecht et al (2014) observed that higher cellular PIC / POC ratios were obtained at lower temperatures for both E. huxleyi and Coccolithus pelagicus. Sett et al (2014), however, found an opposite trend, whereby the PIC / POC ratio increased with temperature in another strain of E. huxleyi.…”

Abstract. Global warming will be combined with predicted increases in thermal variability in the future surface ocean, but how temperature dynamics will affect phytoplankton biology and biogeochemistry is largely unknown. Here, we examine the responses of the globally important marine coccolithophore Emiliania huxleyi to thermal variations at two frequencies (1 d and 2 d) at low (18.5 ∘C) and high (25.5 ∘C) mean temperatures. Elevated temperature and thermal variation decreased growth, calcification and physiological rates, both individually and interactively. The 1 d thermal variation frequencies were less inhibitory than 2 d variations under high temperatures, indicating that high-frequency thermal fluctuations may reduce heat-induced mortality and mitigate some impacts of extreme high-temperature events. Cellular elemental composition and calcification was significantly affected by both thermal variation treatments relative to each other and to the constant temperature controls. The negative effects of thermal variation on E. huxleyi growth rate and physiology are especially pronounced at high temperatures. These responses of the key marine calcifier E. huxleyi to warmer, more variable temperature regimes have potentially large implications for ocean productivity and marine biogeochemical cycles under a future changing climate.

“…Albright et al 2016a ; Mostofa et al 2016 ; Kroeker et al 2017 ). For example, Gao et al ( 2018 ) found that the interactive effects of OA and ocean warming on phytoplankton physiology could be synergistic, neutral, or antagonistic depending on species and prevailing environmental conditions. Equivalent responses have been reported at higher trophic levels (Harvey et al 2013 ).…”

Ocean temperatures are rising; species are shifting poleward, and pH is falling (ocean acidification, OA). We summarise current understanding of OA in the brackish Baltic-Skagerrak System, focussing on the direct, indirect and interactive effects of OA with other anthropogenic drivers on marine biogeochemistry, organisms and ecosystems. Substantial recent advances reveal a pattern of stronger responses (positive or negative) of species than ecosystems, more positive responses at lower trophic levels and strong indirect interactions in food-webs. Common emergent themes were as follows: OA drives planktonic systems toward the microbial loop, reducing energy transfer to zooplankton and fish; and nutrient/food availability ameliorates negative impacts of OA. We identify several key areas for further research, notably the need for OA-relevant biogeochemical and ecosystem models, and understanding the ecological and evolutionary capacity of Baltic-Skagerrak ecosystems to respond to OA and other anthropogenic drivers.

“…Globally, rising temperatures may result in losses of phytoplankton biodiversity in the tropics, but gains in the polar regions (Thomas et al, 2012). It is thought that ocean warming will lead to a poleward range expansion of warm-water species at the expense of cold-water species (Boyd et al, 2010;Gao et al, 2018;Hallegraeff, 2010;Thomas et al, 2012).…”
