“…The most significant changes observed are in the Sr and Sr/Ca records, suggesting the vital effect of Sr uptake by the species (Findlater et al . ). The lack of comparable patterns in other elements (differences in Ca content at Ortel Królewski, Ossówka and Hrud II; Fe at Ortel Królewski; Mn at Hrud; and Mg at Roskosz) may result from local habitats in the lakes, characteristics of the analysed shell material (no replicate analyses available for V. piscinalis ), and/or differences in the life span of species.…”

The elemental shell chemistry of two freshwater snails, Viviparus diluvianus (Kunth) and Valvata piscinalis (Müller) was studied for palaeoenvironmental purposes. The shells were collected from lake sediments from five Holsteinian (Marine Isotope Stage 11) sites in eastern Poland (Ossówka, Hrud II, Roskosz, Ortel Królewski and Szymanowo) and analysed for Ca, Mg, Sr, Mn and Fe. The Fe/Mn molar ratio was used as a redox indicator, with lower values (and high Mn concentrations) pointing to suboxic conditions. These occurred in the beginning of the Taxus zone and during the transition between the Taxus and Pinus‐Larix zones at Ortel Królewski, and in the Holsteinian thermal maximum (Carpinus‐Abies zone) at Roskosz Lake. Strongly reducing conditions, indicated by increased Fe and Fe/Mn values, prevailed at Ortel Królewski palaeolake in the middle of the Taxus zone, in the Pinus‐Larix zone and in the upper part of the Roskosz sequence. Indicators of anoxia correlate with eutrophic conditions, enhanced productivity and oxygen consumption due to organic matter decay. The most distinct environmental changes in the records are comparable to other central and northern European records and to the main climatic oscillations during the Holsteinian, inferred from palynological, malacological and isotopic data.

“…; Findlater et al . ) as the elemental compositions of the shells depend on the water chemistry, which is affected by the local environment and catchment geology, climate, water temperature, salinity, shell mineralogy, growth rate, and vital properties of the species (Rosenthal & Katz ; Wanamaker et al . ; Boulanger & Glascock ).…”

“…Hence the effect of temperature on Na incorporation is negligible (Ishikawa and Ichikuni, 1984;Delaney et al, 1985;Lea et al, 1999;Zeebe and Wolf-Gladrow, 2001). Findlater et al (2014) found a clear relationship between Na concentration and inferred salinity in fossil and modern bivalve shells. It still remains to be tested whether Na incorporation is species-specific, whether the same relationship between Na and salinity occurs in both aragonite and calcite, and how sensitive the potential salinity proxy is.…”

Assessments of the impact of construction, operation, and removal of large infrastructures and other human activities on the marine environment are limited because they do not fully quantify the background baseline conditions and relevant scales of natural variability. Baselines as defined in Environmental Impact Assessments typically reflect the status of the environment and its variability drawn from published literature and augmented with some short term site specific characterization. Consequently, it can be difficult to determine whether a change in the environment subsequent to industrial activity is within or outside the range of natural background variability representative of an area over decades or centuries. An innovative approach that shows some promise in overcoming the limitations of traditional baseline monitoring methodology involves the analysis of shell material (sclerochronology) from molluscs living upon or within the seabed in potentially affected areas. Bivalves especially can be effective biomonitors of their environment over a wide range of spatial and temporal scales. A rapidly expanding body of research has established that numerous characteristics of the environment can be reflected in morphological and geochemical properties of the carbonate material in bivalve shells, as well as in functional responses such as growth rates. In addition, the annual banding pattern in shells can provide an absolute chronometer of environmental variability and/or industrial effects. Further, some species of very long-lived bivalves can be crossdated back in time, like trees, by comparing these annual banding patterns in their shells. It is therefore feasible to develop extended timeseries of certain marine environmental variables that can provide important insights into long temporal scales of baseline variability. We review recent innovative work on the shell structure, morphology, and geochemistry of bivalves and conclude that they have substantial potential for use as monitors of environmental variability and the effects of pollutants and disturbance.

“…Calcium carbonates, such as aragonite, the principal component of recent shells, contain strontium (Findlater et al, 2014;Vonhof et al, 1998). The abundance of shell sherds and the coastal location of the Jabuti and Da Mata sites reinforce the relationship with this environment.…”
