    Abstract Two species of Amphistegina were cultured under four variable DIC concentrations (2340–2570 μM). The variability of trace elements within the foraminiferal shells was measured in the knob area of three individuals for each DIC treatment using LA-ICPMS. In individuals that showed significant growth (identified via 135Ba-enriched seawater), B, Na, and Sr showed an increase with DIC, while K and Mg were slightly lower or unchanged. Sharp transition zones between natural 135Ba and the ∼10-fold increased 135Ba in the shells represent one quarter of a new additional chamber, which occurs roughly once a week. The shape of the transition zone is best described by a logistic equation for population growth. We propose that this reflects the dynamics of seawater vacuoles that serve the biomineralization process and provide Ca and DIC for calcification of Amphistegina as described in previous publications (e.g., Bentov et al., 2009). LA-ICPMS profiles in the central knob (∼70 μm depth) also revealed previously described cyclical changes in concentration of Mg, each apparently representing a growth of a new chamber. Additional elements such as K, Na and U showed similar cycles with the same frequency and phase as the Mg cycles. Sr showed variability with similar frequency but not in-phase to those of the Mg. These multi-element cycles were found both in the newly grown calcite (elevated-135Ba) and in the natural skeleton regardless of the DIC treatments. These high Mg and multi-element cycles seem to be an essential part of the calcification process. They may originate from the interaction with the organic matrix resulting in elevated Mg and other elements in primary calcite while secondary calcite of the lamination process shows lower concentrations. It is also possible that primary calcite is enriched in trace elements if an Amorphous CaCO3 (ACC) or vaterite precursors are involved. In addition, Rayleigh fractionation from a semi-closed reservoir, the presence of high Mg in the lattice or any combination of the previous ...

    Abstract Abstract Background Quantitative data reports are widely produced to inform health policy decisions. Policymakers are expected to critically assess provided information in order to incorporate the best available evidence into the decision-making process. Many other factors are known to influence this process, but little is known about how quantitative data reports are actually read. We explored the reading behavior of (future) health policy decision-makers, using innovative methods. Methods We conducted a computer-assisted laboratory study, involving starting and advanced students in medicine and health sciences, and professionals as participants. They read a quantitative data report to inform a decision on the use of resources for long-term care in dementia in a hypothetical decision scenario. Data were collected through eye-tracking, questionnaires, and a brief interview. Eye-tracking data were used to generate ‘heatmaps’ and five measures of reading behavior. The questionnaires provided participants’ perceptions of understandability and helpfulness as well as individual characteristics. Interviews documented reasons for attention to specific report sections. The quantitative analysis was largely descriptive, complemented by Pearson correlations. Interviews were analyzed by qualitative content analysis. Results In total, 46 individuals participated [students (85%), professionals (15%)]. Eye-tracking observations showed that the participants spent equal time and attention for most parts of the presented report, but were less focused when reading the methods section. The qualitative content analysis identified 29 reasons for attention to a report section related to four topics. Eye-tracking measures were largely unrelated to participants’ perceptions of understandability and helpfulness of the report. Conclusions Eye-tracking data added information on reading behaviors that were not captured by questionnaires or interviews with health decision-makers.

    Abstract Recent advances in spatially-resolved in-situ geochemical analysis enabled recognizing daily variability in B, Mg, Sr and Ba within bivalve shells of the genus Tridacna (e.g. Sano et al., 2012; Warter and Müller, 2017). However, the causes for such daily chemical variations are not fully understood. We carried out laboratory culture experiments to investigate the effect of varying temperatures and light levels on organism physiology and shell geochemistry of the giant clam Tridacna crocea at daily time-resolution. We find that both temperature and light strongly influence shell growth rates. Besides demonstrating light enhanced calcification, we also observe growth inhibition during culture in continuous darkness. ‘Ultra-high resolution’ LA-ICP-MS analysis (Warter and Müller, 2017) in tandem with 135Ba-labelling allows both to identify newly secreted, cultured aragonite and investigate its trace elemental composition at (sub)daily resolution (B/Ca, Mg/Ca, Sr/Ca, Ba/Ca). Overall, average Element/Calcium (El/Ca) ratios reveal an inverse relation with temperature and light. Strikingly, an increasing trend in all El/Ca ratios is observed in the direction of shell growth, which is interpreted to be metabolically-controlled, possibly related to organism ‘stress’. Daily, cyclic trace element variability can be clearly resolved at ~5–15μm in relatively fast growing shells, which experienced a diurnal light cycle but constant temperatures. We conclude that light (but not temperature) is the primary controlling factor responsible for daily trace element variability. We further demonstrate that high El/Ca ratios correspond to growth during night time, i.e. low light intensities, corroborating field observations by Sano et al. (2012). Yet, because light levels were kept constant during night and day, respectively, light intensity cannot account for the entire range of the El/Ca variability. We hypothesize that Tridacna physiology and biochemistry is controlled by a circadian rhythm, initiated by the external factor light, but endogenously mediated by the giant clam and/or its photosynthetic symbionts.
