“…3) resulted in negative SFG and net growth efficiency. A similar case was also reported for the bivalve D. vittatus (Ansell and Sivadas, 1973). In contrast, our result differs from those for other bivalves such as O. edulis and Geukensia demissa, among which an increase in filtration rate can compensate for the increased metabolic cost at warm temperatures (Buxton et al, 1981;Newell and Branch, 1980;Wilbur and Hilbish, 1989).…”

“…Accordingly, differences between the elevations of the oxygen consumption-DW regressions revealed that the metabolic energy expenditure of S. clava increased, particularly at high temperatures (20-25°C), suggesting its limited adjustment of metabolic rate to thermal acclimation. Some mollusks can adjust their metabolic rates almost completely in response to long-term changes in temperature (e.g., Crepidula fornicata and Patella vulgata, Davies, 1966;Newell and Kofoed, 1977), whereas some others are incapable of any acclimatory adjustment to rising temperature (e.g., Ostrea edulis and Donax vittatus, Ansell and Sivadas, 1973;Buxton et al, 1981). As a result, the metabolic characteristics of S. clava are compatible with the latter case, with metabolic losses increasing with temperature.…”

In this study, the energy budget of the Manila clam, Ruditapes philippinarum, was evaluated after one-week acclimation periods at 5, 10, 15, 20, and 25°C. Small clams (151 ± 12 mg DW) and large clams (353 ± 16 mg DW) were fed with the microalgae, Isochrysis galbana. Filtration rate, ingestion rate, assimilation efficiency, oxygenconsumption rate, and ammonia excretion rate were measured. Both filtration rate and ingestion rate of small and large clams were found to be related to temperature. The highest Q 10 values were measured in the range 15-20°C for both small and large clams. Assimilation efficiency of both small and large clams was not significantly influenced by temperature, although the maximum mean values were detected at 20°C. Oxygen consumption rate and ammonia excretion rate of small and large clams were found to be related directly to temperature over the entire range, with a maximum being detected at 25°C. The highest Q 10 value was estimated in the range 10-15°C with regard to oxygen consumption rate, and in the range of 15-20°C with regard to ammonia excretion rate. Scope for growth (SFG) was positive at all temperatures, achieving a maximum value at 20°C in both small and large clams, primarily as a consequence of the enhanced ingestion rate which offset the concomitant elevation in the metabolic rate. In this study we have estimated the thermal optimum for this species at 20°C.

“…Both the grazing rates of the macrofauna and the growth rates of the microorganisms are affected by temperature. However, while components of the metazoan macrofauna living in moderate climates often decrease their activity at high temperatures (Ansell and Sivadas 1973;Aldridge et al 1995), communities of microorganisms are often very productive at such temperatures unless they experience resource limitation (Montagnes and Franklin 2001;Weisse et al 2002;Charlier and Droogmans 2005). A community of microorganisms can change rapidly towards well-adapted species with changing conditions due to the low generation times, while changes in a macrofaunal community occur on a much larger time scale.…”

Control of microbial communities by the macrofauna: a sensitive interaction in the context of extreme summer temperatures?

Climate models predict an increasing frequency of extremely hot summer events in the northern hemisphere for the near future. We hypothesised that microbial grazing by the metazoan macrofauna is an interaction that becomes unbalanced at high temperatures due to the different development of the grazing rates of the metazoans and the growth rates of the microbial community with increasing temperature. In order to test this hypothesis, we performed grazing experiments in which we measured the impact of increasing temperatures on the development of the grazing rates of riverine mussels in relation to the growth rates of a unicellular prey community (a natural heterotrophic flagellate community from a large river). In a first experimental series using Corbicula fluminea as a grazer and under the addition of a carbon source (yeast extract), the increase of the prey's growth rates was considerably stronger than that of the predator's grazing rates when temperatures were increased from 19 to over 25 degrees C. This was also the outcome when the mussels had been acclimatized to warm temperatures. Hereafter, specific experiments with natural river water at temperatures of 25 and 30 degrees C were performed. Again, a strong decrease of the mussels' grazing rates in relation to the flagellate growth rates with increasing temperature occurred for two mussel species (C. fluminea and Dreissena polymorpha). When performing the same experiment using a benthic microbial predator community (biofilms dominated by ciliates) instead of the benthic mussels, an increase of the grazing rates relative to the growth rates with temperature could be observed. Our data suggest that predator-prey interactions (between metazoans and microbes) that are balanced at moderate temperatures could become unbalanced at high temperatures. This could have significant effects on the structure and function of microbial communities in light of the predicted increasing frequency of summer heat waves.
