All datasets in this project can be viewed from the "Dataset Collections" of the project page&nbsp;https://www.bco-dmo.org/project/712799</p> Methods and Sampling: <p>We collected <em>Pisaster ochraceus </em>along the coastline of Carmet Beach, California &nbsp;(38.372172 N, 123.076438 W) in spring of 2018, and <em>Nucella lamellosa</em> at Washington Park in Anacortes, Washington (48.502190 N, -122.691865 W) in July 2018.</p>
<p>We placed 20 <em>Nucella</em> in each of ten containers (33cm x 20cm x 11.5cm) for a total of 200 individuals (25.9mm +/- 2.4mm in length). Half of the containers were supplied with seawater flowing from a chamber above them that held one <em>Pisaster</em> (96.7mm +/- 8.5mm from madreporite to longest arm). This set of containers resulted in morphologically induced snails, where individuals retracted their bodies farther into their shells, potentially from an elongation of shell length (Bourdeau 2009). The other five containers were supplied from a chamber with just seawater (no sea star cue) flowing from it, resulting in non-induced snails. All the <em>Nucella</em> during the experiment were fed <em>ad libitum</em> with <em>Balanus</em> barnacle prey.</p>
<p>We measured various <em>Nucella </em>morphometrics at multiple time points of the experiment. The morphometrics include <em>Nucella </em>weight, the length of the shell from the apex to the notch, the height of the shell from the base of the aperture to the top of the shell, and the retraction capability of <em>Nucella</em>. Retraction into the shell is our focal metric and is defined as the distance from the base of the snail’s aperture by the columella to its operculum when the individual is fully retracted. The induction (or non-induction) period lasted from July 2, 2018 to November 14, 2018.&nbsp;&nbsp;Further morphometric data were collected in February 2019 but were not used in the analysis.</p>
<p>To test the effect of predator cue on <em>Nucella</em> morphology, we analyzed whether there was an effect of <em>Pisaster</em> cue on retractability both at the start and end of the induction period. Both containers and individual <em>Nucella</em> were included as random effects.<br />

Trophic consequences of ocean acidification: Intertidal sea star predators and their grazer prey

Trophic consequences of ocean acidification: Intertidal sea star predators and their grazer prey
<p><em>NSF Award Abstract:</em><br />
The absorption of human-produced carbon dioxide into the world's oceans is altering the chemistry of seawater, including decreasing its pH. Such changes, collectively called "ocean acidification", are expected to influence numerous types of sea creatures. This project examines how shifts in ocean pH affect animal behavior and thus interactions among species. It uses a case study system that involves sea star predators, snail grazers that they eat, and seaweeds consumed by the latter. The rocky-shore habitats where these organisms live have a long history of attention, and new findings from this work will further extend an already-large body of marine ecological knowledge. The project provides support for graduate and undergraduate students, including underrepresented students from a nearby community college. The project underpins the development of a new educational module for local K-12 schools. Findings will moreover be communicated to the public through the use of short film documentaries, as well as through established relationships with policy, management, and industry groups, and contacts with the media.</p>
<p>Ocean acidification is a global-scale perturbation. Most research on the topic, however, has examined effects on single species operating in isolation, leaving interactions among species underexplored. This project confronts this knowledge gap by considering how ocean acidification may shift predator-prey relationships through altered behavior. It targets as a model system sea stars, their gastropod grazer prey, and macoalgae consumed by the latter, via four lines of inquiry. 1) The project examines the functional response of the focal taxa to altered seawater chemistry, using experiments that target up to 16 discrete levels of pH. This experimental design is essential for identifying nonlinearities and tipping points. 2) The project addresses both consumptive and non-consumptive components of direct and indirect species interactions. The capacity of ocean acidification to influence such links is poorly known, and better understanding of this issue is a recognized priority. 3) The project combines controlled laboratory experiments with field trials that exploit tide pools and their unique pH signatures as natural mesocosms. Field tests of ocean acidification effects are relatively rare and are sorely needed. 4) A final research phase expands upon the above three components to address effects of ocean acidification on multiple additional taxa that interact in rocky intertidal systems, to provide a broad database that may have utility for future experiments or modeling.</p>
