“…These organisms have few planktonic prey in the water and have to derive most of their carbon from the symbiotic dinoflagellates (Muscatine, McCloskey, & Marian, 1981). The δ 13 C values of the coral tissue are similar to those of the symbionts, and any heterotrophic input from the host will be masked by the large autotrophic input from the symbionts Leal, Rocha, Anaya-Rojas, Cruz, & Ferrier-Pagès, 2017;Nahon et al, 2013;Reynaud et al, 2002). Finally, in autotrophic symbioses, the δ 13 C signature of the symbiotic association also largely varies according to the photosynthetic rates of the symbionts, which is primarily associated with light irradiance: Carbon fractionation increases with decreasing irradiance, which leads to a lower δ 13 C signature under low light (Heikoop et al, 2000).…”

Stable isotopes as tracers of trophic interactions in marine mutualistic symbioses

Mutualistic nutritional symbioses are widespread in marine ecosystems. They involve the association of a host organism (algae, protists, or marine invertebrates) with symbiotic microorganisms, such as bacteria, cyanobacteria, or dinoflagellates. Nutritional interactions between the partners are difficult to identify in symbioses because they only occur in intact associations. Stable isotope analysis (SIA) has proven to be a useful tool to highlight original nutrient sources and to trace nutrients acquired by and exchanged between the different partners of the association. However, although SIA has been extensively applied to study different marine symbiotic associations, there is no review taking into account of the different types of symbiotic associations, how they have been studied via SIA, methodological issues common among symbiotic associations, and solutions that can be transferred from one type of association with another. The present review aims to fill such gaps in the scientific literature by summarizing the current knowledge of how isotopes have been applied to key marine symbioses to unravel nutrient exchanges between partners, and by describing the difficulties in interpreting the isotopic signal. This review also focuses on the use of compound‐specific stable isotope analysis and on statistical advances to analyze stable isotope data. It also highlights the knowledge gaps that would benefit from future research.

“…Weak to absent seasonal dynamics were found for Porpitidae, which depicted more stable numbers throughout the year and between years, but with markedly rapid fluctuations ( Figure 4B). Taxa within the family Porpitidae contain symbiotic cells (Bouillon and Boero, 2000;Chowdhury et al, 2016), which can provide a food source (e.g., Pitt et al, 2005;Leal et al, 2017) and thus may make them less responsive to seasonal prey availability. Consequently, Porpitidae occurrence patterns in this study were better described by rapid fluctuations and the lack of a seasonal pattern, which corresponds to previous findings of occurrence dynamics of the symbiotic Cassiopea sp.…”

Gelatinous Zooplankton in the Surface Layers of the Coastal Central Red Sea

Characterizations of gelatinous zooplankton communities are necessary for an improved understanding of the ecological and temporal dynamics of such communities and their composing taxa. Yet, studies on gelatinous zooplankton communities are scarce in the Red Sea, which is characterized by extreme temperature, high salinity and oligotrophic conditions. Here, we analyzed the occurrence of gelatinous zooplankton taxa in a timeseries of epipelagic samples taken from September 2016 to May 2018 in the central Red Sea to deliver the first complete characterization of gelatinous zooplankton in the Red Sea. General seasonal dynamics were found over the year, where higher gelatinous zooplankton abundances were relate to mostly with lower temperatures, lower salinity and to a lesser extent, with chlorophyll a, cross-shelf and along-shelf Ekman transport. Tunicates and siphonophores presented seasonal patterns, whereby total biovolume values were 10 3-10 5 higher in winter-early spring than in summer, and numbers > 100 higher in the bloom event of 2017/2018 than in 2016/2017. Ulmaridae (Aurelia sp.) peaked after the main bloom event of siphonophores and tunicates, and dominated total biovolume when present. Porpitidae was consistently present and showed no clear seasonality. Our results suggest that there is a noticeable seasonal trend in gelatinous zooplankton, marked by high occurrences in winter-early spring, very low occurrences over summer, and mostly dominated by Salpidae and Dyphidae. Porpitidae was a dominating group with non-seasonal occurrence, and Ulmaridae was also dominating but with very short and few occurrences. In addition, low abundance and biovolume (max. 8 ind m −3 and max. 10 3-10 6 mm 3 m −3) suggest that oligotrophic conditions may be limiting the productivity of gelatinous zooplankton communities in the Red Sea.

“…Bioindicators were selected based on their presence in long-term benthic composition data and their use in previous nutrient enrichment and bioindicator studies (Risk et al, 2001;Fichez et al, 2005;Cooper et al, 2009;Fabricius et al, 2012). Bioindicators included whole fronds of mature foliose brown macroalgae with the apical tips (Sargassum sp., Littler et al, 1991;Schaffelke, 1999), filamentous green macroalgae (Chlorodesmis sp., Schaffelke, 1999), cyanobacteria (Ford et al, 2018), soft corals (Sarcophyton sp., Fleury et al, 2000, turf algal matrix (Graham et al, 2018), sponges (Demospongaie: Ward-Paige et al, 2005;Lamb et al, 2012), and zoanthids (Palythoa sp., Leal et al, 2017). For turf algae, branches of dead Acropora spp.…”

“…1a; Zanden & Rasmussen, 2001;Fox et al, 2018). There has been little research into zoanthids as potential indicators of nutrient runoff (Leal et al, 2017), but Costa Jr. et al (2008 found that phosphorus and silica water concentrations had positive effects on both algal and zoanthid growth, and negative effects on coral cover. However, unlike primary producers, zoanthids have to balance autoand heterotrophic processes for acquiring sources of C and N (Smit, 2001;Leal et al, 2017) because, like scleractinian corals, they have photosynthetic symbionts in their tissues (Hoegh-Guldberg et al, 2004;Fox et al, 2018).…”
