Aspects ofthe ecology oforganisms that utilize this habitat can, in certain cases, be used as indicators of ocean conditions. In this study, diet ofthe Leach's storm-petrel (Oceanodroma leucorhoa) is examined to determine ifevidence ofchanging ocean conditions can be found in the diet. Regurgitations were collected from the birds in order to describe diet. Euphausiids and fish composed 80 - 90% ofthe diet in both years, with composition of each diametrically different between years. Other items found in samples included . hyperiid and gammariid amphipods, cephalopods, plastic pieces and a new species of Cirolanid isopod. -

In the Laboratory with an ample supply of running sea water, many of these animals lived for several days and I was able to observe their feeding preferences and rates. On the basis of these obervations and the reports of other workers it is possible to construct a preliminary diagram of the neuston food web. Ianthina prolongata Of the three species of Ianthina washed ashore, I. janthina forma balteata, I. umbilicata, and I. prolongata, I. prolongata was most abundant. I was able to collect more than 160 of them in less than an hour. -

These included the purple snail, Ianthina, the nudibranchs, Glaucus and Fiona, the crab, Planes, the barnacle, Lepas, the siphonophore, Physalia, and the chondrophore Velella. This stranding provided an opportunity to close some of the gaps in our understanding of the neuston food web. The food and feeding habits of the Portuguese man-of-war, Physalia, are well known. In an earlier paper (BIERI, 1961) I reported some studies of the food of Velella, but I could find no reports of the food of Parpita. As with Velella in the 1961 study, individual porpitas were collected alive from the sea surface, divided into four size groups, and preserved in formalin about one half hour after collection. In the laboratory the porpitas were measured and all the digestive appendages ("gonozoids" and the "oral chamber") were removed from each specimen. -

Trophic Interactions Between Two Neustonic Organisms: Insights from Bayesian Stable Isotope Data Analysis Tools
Belg. J. Zool., 146 (2) : 123–133 July 2016 Trophic interactions between two neustonic organisms: insights from Bayesian stable isotope data analysis tools Gilles Lepoint 1,*, Laurent Bernard 1, Sylvie Gobert 1 & Loïc N. Michel 1 1 Laboratory of Oceanology, FOCUS centre, University of Liège. * Corresponding Author: [email protected] ABSTRACT. The by-the-wind sailor Velella velella (Linnaeus, 1758) and its predator, the violet snail Janthina globosa (Swainson, 1822) are both floating neustonic organisms. Despite their global oceanic distribution and widespread blooms of V. velella in recent years, many gaps remain in our understanding about prey/predator interactions between these two taxa. Using stable isotope ratios of carbon and nitrogen, we aimed to study the trophic relationship between V. velella and J. globosa and investigate diet variation of V. velella and J. globosa in relation to individuals’ size. Bayesian approaches were used to calculate isotopic niche metrics and the contribution of V. velella to the J. globosa diet. Our data showed that the isotopic niche of V. velella differed markedly from that of J. globosa. It was larger and did not overlap that of the J. globosa, indicating a more variable diet but at a lower trophic level than J. globosa. The isotopic niche of V. velella also varied according to the size class of the individual. Small individuals showed a larger isotopic niche than larger animals and low overlap with those of the larger individuals. J. globosa displayed very low isotopic variability and very small isotopic niches. In contrast, there were no isotopic composition nor isotopic niche differences between J. -
