Data and Code for: Biogeographic variation in mussel shell thickness and drilling predation on rocky shores
<p><strong><u><span>Abstract: </span></u></strong></p> <p><span>Predator and prey species are often distributed over broad geographic ranges where reciprocal selection can shape the interactions between them. However, few studies have addressed how environmentally-driven variation in prey traits might create a landscape of selection that shapes the evolution of predator traits. We investigated whether variation in the drilling capacity of a predatory snail (the channeled dogwhelk, <em>Nucella canaliculata</em>) is associated with variation in prey defenses (mussel shell thickness) over ~1,000 km of coastline in the northeast Pacific. To test this hypothesis, we first hatched and raised snails from 6 populations under common laboratory conditions for a year. We then challenged these naïve snails with a series of mussels (<em>Mytilus californianus</em>) of increasing shell thickness to quantify their maximum drilling capabilities. Dogwhelks from California drilled mussels that were up to 3.4 times thicker than those handled by dogwhelks from Oregon. To quantify the spatial mosaic of mussel shell thickness, we analyzed <em>M. californianus</em> shells collected from the same six sites during three time periods (2000-2001, 2008-2009 and 2019). In the two earlier sampling periods, mussels from the central Oregon coast were consistently and substantially thicker than those from California. Thus, our findings are consistent with the hypothesis that prey defenses vary across the overlapping geographic ranges of these species, with the potential for strong prey-driven selection on the predator in California, and a co-evolutionary cold spot on the Oregon coast. However, relative to prior decades, mussel shells appear to be thinning, particularly on the Oregon coast. These changes are consistent with recent ocean acidification research in the northeast Pacific and may signal shifts in the selective landscape that has shaped the evolution of this dogwhelk-mussel interaction. Given the rapid pace of global environmental change, our study highlights the importance of studying species interactions within an explicit geographic context of shifting selection pressures. </span></p>

Dataset: Stable oxygen and carbon isotopes in freshwater pearl mussels from ultrastructurally distinct shell portions
<p>Oxygen isotopes in stream water can serve as natural tracers of watershed dynamics. Freshwater pearl mussels provide δ<sup>18</sup>O<sub>water</sub> estimates that overcome temporal and spatial limitations of instrumental records. The reliability of shell‑based δ<sup>18</sup>O<sub>water</sub> reconstructions depends on understanding which shell layer biomineralizes closer to oxygen isotopic equilibrium with ambient water<em>.</em></p> <p>This dataset contains isotope data obtained from freshwater pearl mussel shells<em>,</em> as discussed in the article titled "Biologically driven isotope fractionation in ultrastructurally different shell portions of freshwater pearl mussels <em>(Margaritifera margaritifera):</em> Implications for stream water δ<sup>18</sup>O reconstructions".</p> <p>The dataset includes δ<sup>18</sup>O and δ<sup>13</sup>C values from field-collected and tank-reared bivalve shells, complemented by <em>in-situ</em> δ<sup>18</sup>O<sub>water</sub> measurements from the tanks and shell growth rates of the tank-reared specimens.</p>
