“…v=79RvGRUdnwE). Stable isotope evidence from this and other studies also indicates that fucoid macroalgae are a significant source of nutrition to P. vulgata; the limpets are not only ingesting macroalgal foods, but they are also assimilating them into their tissues (Campbell 2004, Riera et al 2009, Schaal et al 2010.…”

“…obs.). Lorenzen (2007) also recorded P. vulgata feeding on stranded macroalgae during periods of emersion, and the results of stable isotope analyses from several sources provide strong evidence to suggest that macroalgae may be a more significant source of organic carbon to P. vulgata than previously appreciated (Campbell 2004, Riera et al 2009, Schaal et al 2010, Notman 2011.…”

“…Laminaria digitata and Palmaria palmata, have relatively high δ 13 C values of −15 ‰ (Schaal et al 2010). Similarly as with δ (Schaal et al 2010). Lower quality of bottom SPM was evident from lipid distributions having lower quantities of labile PUFAs and phytoplankton biomarkers (Table 6, Fig.…”

“…Studies of food webs in hard-bottom ecosystems have described several possible and variable trophic pathways for phytoplankton and reef-associated algae. For example, algae growing on hard structures contribute to the diet of nearby nonreef-dwelling consumers (Kang et al 2003;Behringer and Butler 2006;Doi et al 2008;Fukumori et al 2008), and phytoplankton or epiphytes may be important basal resources to consumers inside dense macroalgal beds (Kang et al 2008;Golléty et al 2010;Schaal et al 2010). However, the relative importance of phytoplankton and endemic micro-and macroalgae to platform-based food webs has not been investigated.…”

What Is the Relative Importance of Phytoplankton and Attached Macroalgae and Epiphytes to Food Webs on Offshore Oil Platforms?

Offshore oil platforms function as artificial reefs, but little is known about the food webs that fuel platform‐dwelling biota. Here, we use carbon and nitrogen isotopes in tissues of biota from two offshore oil platforms to estimate the importance of phytoplankton and platform‐associated macroalgae and epiphytic microalgae to the diets of platform‐dwelling consumers. Although the consumption of macroalgae was indicated for small, mobile consumers including crabs, amphipods, and harpacticoid copepods, both a Bayesian mixing model and temporal changes in isotope composition identified phytoplankton as the most important basal resource for these consumers. Sessile suspension‐feeding barnacles and oysters consumed phytoplankton and epiphytes, and probably redirected large amounts of pelagic production to other consumers. Secondary consumers including syllid polychaetes and the blennies, Molly Miller Scartella cristata and Tessellated Blenny Hypsoblennius invemar, exhibited a distinct contribution from epiphytes although large ranges in all potential basal resources were observed. Elemental and isotope analysis of the gut contents of individuals indicated that the nektonic Gray Triggerfish Balistes capriscus was omnivorous, directly consuming reef‐derived macroalgae and epiphytes as well as animal tissue. Although we found that reef‐derived resources entered benthic and nektonic food webs surrounding platforms, phytoplankton was the dominant basal resource fueling platform‐dwelling communities at the time of our study, and no consumer studied specialized on a diet of red macroalgae. If these findings are generally representative, platform‐derived benthic algae would not be integral to food‐web function on artificial reefs, and reef function should be similar in areas both favorable to and unfavorable to in situ algal growth.
