Data archive: Trophic structure of cold-water coral communities revealed from the analysis of tissue isotopes and fatty acid composition
<p>Data belonging to the paper: </p> <p>Dick van Oevelen, Gerard C. A. Duineveld, Marc S. S. Lavaleye, Tina Kutti and Karline Soetaert (2017) Trophic structure of cold-water coral communities revealed from the analysis of 55 tissue isotopes and fatty acid composition. Marine Biology Research, DOI: https://doi.org/10.1080/17451000.2017.1398404</p> <p>Abstract:</p> <p>The trophic structure of cold-water coral reef communities at two contrasting locations, the 800-<br> m deep Belgica Mounds (Irish margin) and 300-m deep Træna reefs (Norwegian Shelf), was<br> investigated using stable isotope (δ13C and δ15N) and fatty-acid composition analysis. A<br> broad range of specimens, with emphasis on (commercial) fish species, and organic matter<br> sources were sampled using a variety of tools. Irrespective of the environmental and<br> geographical setting, the δ15N values indicated that the food web encompasses roughly 1.5<br> to 3 trophic levels. Mobile echinoderms, i.e. sea urchins and sea stars, had highest δ15N<br> values, indicative of a high trophic position in the food web. The fraction of bacterial fatty<br> acids in reef fauna was generally low (<5%), indicating that enhanced bacterial production in<br> the water column through seafloor seepage of nutrients (‘hydraulic theory’) does not form a<br> significant energy pathway into the food web. The high fraction of algal and essential fatty<br> acids in reef fauna and fish at both locations indicates a close coupling with surface<br> productivity, but the transport mechanism depends on the hydrographic setting. At Træna,<br> Calanus copepods and euphausiids form an additional link between primary production and<br> fish, which is largely absent at Belgica Mounds. At Belgica Mounds, the reef community is<br> primarily supported by phytodetritus, as evidenced by the high contribution of algal fatty<br> acids in faunal tissue and seasonal chlorophyll a deposition and marine snow at the reef. The<br> environmental setting of cold-water coral reefs influences the structure of the associated<br> food web.</p>
Figure 2. The structures of the two tables from the Dex Online database-ADX – Agent for Morphologic Analysis of Lexical Entries in a Dictionary
<p>Dex Online is a project initiated and coordinated by Catalin Francu [3]. He intended to<br> realise an online database for all the words in the Romanian language, using the main explanatory<br> dictionaries, dictionaries of synonyms, neologisms, published by the Romanian Academy and other<br> scientific forums.<br> The database was completed by volunteers, similarly to the Wikipedia system. They actually<br> transcribed the information from different important dictionaries, but many words have been<br> electronically entered by two companies (Siveco and Litera International Publishing House).</p>

Fig. 39 in Taxonomic analysis of the genital plates and associated structures in Ophiuroidea (Echinodermata)
Fig. 39. Bayesian phylogenetic tree, inferred from the same matrix as in figure 37, but with all genital plate characters removed. Numbers at nodes represent posterior probabilities. Extinct species are marked with a cross. The overall structure is more comb-shaped, and most clades are no longer recovered.
Fig. 38 in Taxonomic analysis of the genital plates and associated structures in Ophiuroidea (Echinodermata)
Fig. 38. Same tree as in Fig. 37, clades collapsed into families. Coloured ellipses mark clades that are paraphyletic, compared to the molecular phylogeny in O'Hara et al. (2017). Ophiopsilina Matsumoto, 1915 is nested inside Gnathophiurina Matsumoto, 1915, instead of being a sister clade. Ophioleucida Matsumoto, 1915 is in Ophiacanthida O'Hara, Hugall, Thuy, Stöhr & Martynov, 2017 instead of being a sister clade to Amphilepidida O'Hara, Hugall, Thuy, Stöhr & Martynov, 2017. Ophioscolecida O'Hara, Hugall, Thuy, Stöhr & Martynov, 2017 may be a sister clade to Ophiacanthida, but the relationships in this group of clades are unclear. Ophienigma Stöhr & Segonzac, 2005 and Ophiopus Ljungman, 1867 may constitute a new family. The relationships of Ophiomusaidae O'Hara, Stöhr, Hugall, Thuy & Martynov, 2018 could not be resolved.
