  • Feeding and growth efficiency in a pelagic chaetognath, Zonosagitta nagae reared in the laboratory

    Otake, S., Takahashi, K. and Shimode, S.

    Chaetognaths are ubiquitous in the marine environment and are among the most abundant carnivorous plankton. Nevertheless, characterization of physiological parameters remains limited largely due to the difficulty in obtaining the data from pelagic chaetognaths in laboratory studies. This study therefore aimed to determine the feeding and growth rates of Zonosagitta nagae under laboratory rearing condition. A total of 54 field-collected chaetognaths with maturity Stage I and II ranging from 5 to 12 mm in body length collected in June, August and October were individually incubated at 20–22°C with excess copepod prey and growth parameters were obtained from 26 individuals that survived ~10–46 days. For Z. nagae, ingestion and growth rates increased with body dry weight, and both parameters were significantly related, indicating that gross growth efficiency was ~47%. Specific ingestion rates ranged from 0.03 to 0.43 d−1 and tended to decrease with an increase of size of the chaetognaths. Individual specific growth rate varied widely in small-sized individuals (~6 mm), ranging from −0.103 to 0.135, but became relatively constant (~0.032) with increasing size. Overall the study results suggest that Z. nagae is characterized by high gross growth efficiency, which is in striking contrast with previously studied inshore species.

  • Photochemical Production and Biological Consumption of CO in the SML of Temperate Coastal Waters and Their Implications for Air-sea CO Exchange.

    Sugai, Y., K. Tsuchiya, S. Shimode and T. Toda

    The sea surface microlayer (SML), less than 1,000‐μm uppermost layer of the ocean water column, is located at the air‐sea interface and plays critical roles in global biogeochemical cycles and climate change through air‐sea gas exchange. To clarify the significance of the dynamics of carbon monoxide (CO) in the SML, where active photochemical and biological processes are expected, in air‐sea CO exchange, the production and consumption of CO in the SML and its sea‐air emission were investigated in temperate coastal waters. In the SML, the light‐normalized photochemical CO production rate was relatively high from spring to autumn (median: 2.57 nM [kWh m−2]−1) when relatively high absorbance of chromophoric dissolved organic matter (0.55 m−1) was observed. Biological CO consumption rate constant in the SML showed relatively high values from spring to autumn (mean ± standard deviation: 0.060 ± 0.010 h−1) during the period of relatively high water temperature (22.3 ± 2.7 °C). The calculated sea‐air CO flux (F) varied similarly to CO concentration in the subsurface water. Comparison among the production, consumption, and sea‐air emission of CO in the SML suggests that biological consumption in the SML can be ignored in air‐sea CO exchange throughout the year whereas photochemical production in the SML enhances F during summer under intense light, active biological production, and weak wind conditions. Further, seawater warming experiments found the tendency of the stimulation of biological CO consumption by water temperature increase from spring to autumn, which suggests negative but insignificant feedback on global warming.

  • Incorporation characteristics of exogenous 15N-labeled thymidine, deoxyadenosine, deoxyguanosine and deoxycytidine into bacterial DNA

    Bacterial production has been often estimated from DNA synthesis rates by using tritium-labeled thymidine. Some bacteria species cannot incorporate extracellular thymidine into their DNA, suggesting their biomass production might be overlooked when using the conventional method. In the present study, to evaluate appropriateness of deoxyribonucleosides for evaluating bacterial production of natural bacterial communities from the viewpoint of DNA synthesis, incorporation rates of four deoxyribonucleosides (thymidine, deoxyadenosine, deoxyguanosine and deoxycytidine) labeled by nitrogen stable isotope (15N) into bacterial DNA were examined in both ocean (Sagami Bay) and freshwater (Lake Kasumigaura) ecosystems in July 2015 and January 2016. In most stations in Sagami Bay and Lake Kasumigaura, we found that incorporation rates of deoxyguanosine were the highest among those of the four deoxyribonucleosides, and the incorporation rate of deoxyguanosine was approximately 2.5 times higher than that of thymidine. Whereas, incorporation rates of deoxyadenosine and deoxycytidine were 0.9 and 0.2 times higher than that of thymidine. These results clearly suggest that the numbers of bacterial species which can incorporate exogenous deoxyguanosine into their DNA are relatively greater as compared to the other deoxyribonucleosides, and measurement of bacterial production using deoxyguanosine more likely reflects larger numbers of bacterial species productions.
